+**SECURITY**
+* Fix for CVE-2014-2913
+* Added function to clean the environment before forking. (John Frickson)
+
+**ENHANCEMENTS**
+* Added support for optional config file to check_nrpe. With the new SSL
+  parameters, the line was getting long. The config file is specified with
+  --config-file=<path> or -f <path> parameters. The config file must look
+  like command line options, but the options can be on separate lines. It
+  MUST NOT include --config-file (-f), --command (-c) or --args (-a). If any
+  options are in both the config file and on the command line, the command line
+  options are used.

+* Added "nrpe-uninstall" script to the same directory nrpe get installed to (John Frickson)
+* Updated code so configure && make will work on AIX, HP-UX, Solaris, OS X.
+  There should be no errors or warnings. Let me know if any errors or
+  warning appear (John Frickson)
+* Added command-line option to prevent forking, since some of the init
+  replacements (such as systemd, etc.) don't want daemons to fork (John Frickson)
+* Added autoconf macros and additional files to better support multi-platform
+  config and compile. The default will still set up to install to
+  /usr/local/nagios but I added a new configure option:
+  '--enable-install-method=<method>'. If <method> is 'opt', everything will
+  install to '/opt/nagios'. If <method> is 'os', installation will be to O/S-
+  and distribution-specific locations, such as /usr/sbin, /usr/lib/nagios,
+  /etc/nagios, and so on.
+* Added additional init and inetd config files to support more systems,
+  including SuSE, Debian, Slackware, Gentoo, *BSD, AIX, HP-UX, Solaris, OS X.
+* Added listen_queue_size as configuration option (Vadim Antipov, Kaspersky Lab)
+* Reworked SSL/TLS. See the README.SSL.md file for full info. (John Frickson)
+* Added support for version 3 variable sized packets up to 64KB. nrpe will
+  accept either version from check_nrpe. check_nrpe will try to send a
+  version 3 packet first, and fall back to version 2. check_nrpe can be forced
+  to only send version 2 packets if the switch `-2` is used. (John Frickson)
+* Added extended timeout syntax in the -t <secs>:<status> format. (ABrist)
+
+**FIXES**
+* Fixed configure to check more places for SSL headers/libs. (John Frickson)
+* Added ifdefs for complete_SSL_shutdown to compile without SSL. (Matthew L. Daniel)

+* NRPE should not start if cannot write pid file (John Frickson)
+* Fixed out-of-bounds error (return code 255) for some failures (John Frickson)
+* Connection Timeout and Connection Refused messages need a new line (Andrew Widdersheim)
+* allowed_hosts doesn't work, if one of the hostnames can't be resolved by dns (John Frickson)
+* allowed_hosts doesn't work with a hostname resolving to an IPv6 address (John Frickson)
+* Return UNKNOWN when issues occur (Andrew Widdersheim)
+* NRPE returns OK if check can't be executed (Andrew Widdersheim)
+* nrpe 2.15 [regression in Added SRC support on AIX - 2.14] (frphoebus)

+# Contributing
+
+Thank you for considering contributing your time and effort to this Nagios project.
+This document serves as our guidelines for contribution. Keep in mind that these 
+are simply *guidelines* - nothing here is set in stone.
+
+## Questions
+
+If you have a question, you don't need to file an Issue. You can simply connect
+with the Nagios Support Team via the 
+[Nagios Support Forum](https://support.nagios.com/forum/).
+
+Not to say that you **can't** open an Issue - but you'll likely get a much faster
+response by posting it on the forum.
+
+## Ideas
+
+If you have an idea your best bet is to open an Issue. This gets it on the radar much
+quicker than any other method.
+
+First, let's define what an "Idea" really is. An Idea is simply an 
+[Enhancement](#enhancements) request in its infancy. 
+There's really nothing to it!
+
+Something as simple as "I think that this project should somehow connect with a 
+widget" is a valid Idea.
+
+These are unrefined and raw. That's why you open an issue - so everyone gets a chance
+to chime in and come up with a plan!
+
+## Feedback
+
+Feedback can be given via several methods. The *easiest* method is by opening an Issue.
+You're more than welcome to leave feedback on the 
+[Nagios Support Forum](https://support.nagios.com/forum/) as well.
+
+By opening an Issue, however, you're insuring that the maintainers and reviewers are
+the first ones to see the feedback. In most cases, this is likely ideal.
+
+## Bugs
+
+Here's where it starts to get serious. 
+
+Following the guidelines outlined in this section allows the maintainers, developers, and
+community to understand and reproduce your bug report.
+
+Make sure to search existing open and closed [Issues](https://guides.github.com/features/issues/)
+before opening a bug report. If you find a closed Issue that seems like it's the same 
+thing that you're experiencing, open a new Issue and include a link to the original Issue 
+in the body of the new one.
+
+**If you have a bug, you *NEED* to open an Issue.**
+
+Not only that, but when you open the Issue, this is what we ***absolutely require***:
+
+* Use a clear and concise title for the Issue to identify the problem accurately
+
+* Describe the bug with as much detail as you can
+
+* Include the version of the project containing the bug you're reporting
+
+* Include your operating system information (`uname -a`)
+
+* Include a list of third party modules that are installed and/or loaded
+
+* Explain the behavior you expected to see (and why) vs. what actually happened
+
+Once you've got that covered - there's still more to include if you want to
+make a ***killer*** report:
+
+* Describe the ***exact steps*** that reproduce the problem
+
+* Provide **specific** examples to demonstrate those steps
+ 
+* If your bug is from an older version, make sure test against the latest (and/or the `maint` branch)
+
+* Include any screenshots that can help explain the issue
+
+* Include a file containing `strace` and/or `valgrind` output
+
+* Explain when the problem started happening: was it after an upgrade? or was it always present?
+
+* Define how reliably you can reproduce the bug
+
+* Any other information that you decide is relevant is also welcome
+
+## Enhancements
+
+An enhancement is either a completely new feature or an improvement to existing 
+functionality. We consider it to be a bit different than idea - based solely
+on the fact that it's more detailed than an idea would be.
+
+So you've got an idea for an ehancement? Great!
+
+Following the guidelines outlined in this section allows maintainers, developers, and
+the community to understand your enhancement and determine whether or not it's worth 
+doing and/or what's involved in carrying it out.
+
+Make sure to search open and closed Issues and Pull Requests to determine if
+someone has either submitted the enhancement. If you feel like your enhancement
+is similar to one found, make sure to link the original in your request.
+
+Enhancements are submitted by opening an Issue.
+
+Unlike an [Idea](#idea), when you decide to submit your enhancement and open 
+the Issue, we require at least the following information:
+
+* Use a clear and descriptive title to illustrate the enhancement you're requesting
+
+* Describe the current behavior (if it exists) and what changes you think should be made
+
+* Explain the enhancement in detail - make sure it makes sense and is easily understandable
+
+* Specify why the enhancement would be useful and who it would be useful to
+
+* If there is some other project or program where this enhancement already exists, make sure
+to link to it
+
+Beyond that, there are a few more things you can do to make sure you **really** get your
+point across:
+
+* Create a mockup of the enhancement (if applicable) and attach whatever files you can
+
+* Provide a step-by-step description of the suggested enhancement
+
+* Generate a fully dressed use-case for the enhancement request
+
+* Create a specification for the preferred implementation of the enhancement
+
+* Include a timeline regarding development expectations towards the request
+
+## Submitting Code
+
+Everything else in this document has lead up to this moment - how can ***you*** submit 
+code to the **project**.
+
+We allow code submissions via [Pull Requests](https://help.github.com/articles/about-pull-requests/).
+These let you (and us) discuss and review any changes to code in any repository you've made.
+
+How to create and manage Pull Requests is outside of the scope of this document, but make
+sure to check out GitHub's official documentation ([link here](https://help.github.com/))
+to get a handle on it.
+
+While you're forking the repository to create a patch or an enhancement, create a *new 
+branch* to make the change - it will be easier to submit a pull request using a new
+branch in your forked repository!
+
+When you submit a Pull Request, make sure you follow the guidelines:
+
+* Make sure you're submitting to the proper branch. Branch `maint` is used for the 
+**next** bugfix release. The next enhancement release branch will vary.
+
+* ***NEVER*** submit a Pull Request to `master` branch.
+
+* Keep commit messages as concise as possible.
+* Update the appropriate files in regards to your changes:
+
+  * `CHANGES`
+
+  * `THANKS`
+
+* End all committed files with a newline.
+
+* Test your changes and include the results as a comment.

+The GNU General Public License, Version 2, June 1991 (GPLv2)
+============================================================
+
+> Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+> 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+
+Preamble
+--------
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to most
+of the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software is
+covered by the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom to
+distribute copies of free software (and charge for this service if you wish),
+that you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs; and that you know you can
+do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to deny
+you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of the
+software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for a
+fee, you must give the recipients all the rights that you have. You must make
+sure that they, too, receive or can get the source code. And you must show them
+these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2) offer
+you this license which gives you legal permission to copy, distribute and/or
+modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients to
+know that what they have is not the original, so that any problems introduced by
+others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We wish
+to avoid the danger that redistributors of a free program will individually
+obtain patent licenses, in effect making the program proprietary. To prevent
+this, we have made it clear that any patent must be licensed for everyone's free
+use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+
+Terms And Conditions For Copying, Distribution And Modification
+---------------------------------------------------------------
+
+**0.** This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms of
+this General Public License. The "Program", below, refers to any such program or
+work, and a "work based on the Program" means either the Program or any
+derivative work under copyright law: that is to say, a work containing the
+Program or a portion of it, either verbatim or with modifications and/or
+translated into another language. (Hereinafter, translation is included without
+limitation in the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered by
+this License; they are outside its scope. The act of running the Program is not
+restricted, and the output from the Program is covered only if its contents
+constitute a work based on the Program (independent of having been made by
+running the Program). Whether that is true depends on what the Program does.
+
+**1.** You may copy and distribute verbatim copies of the Program's source code
+as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this License
+and to the absence of any warranty; and give any other recipients of the Program
+a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you may at
+your option offer warranty protection in exchange for a fee.
+
+**2.** You may modify your copy or copies of the Program or any portion of it,
+thus forming a work based on the Program, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that you also
+meet all of these conditions:
+
+*   **a)** You must cause the modified files to carry prominent notices stating
+    that you changed the files and the date of any change.
+
+*   **b)** You must cause any work that you distribute or publish, that in whole
+    or in part contains or is derived from the Program or any part thereof, to
+    be licensed as a whole at no charge to all third parties under the terms of
+    this License.
+
+*   **c)** If the modified program normally reads commands interactively when
+    run, you must cause it, when started running for such interactive use in the
+    most ordinary way, to print or display an announcement including an
+    appropriate copyright notice and a notice that there is no warranty (or
+    else, saying that you provide a warranty) and that users may redistribute
+    the program under these conditions, and telling the user how to view a copy
+    of this License. (Exception: if the Program itself is interactive but does
+    not normally print such an announcement, your work based on the Program is
+    not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be reasonably
+considered independent and separate works in themselves, then this License, and
+its terms, do not apply to those sections when you distribute them as separate
+works. But when you distribute the same sections as part of a whole which is a
+work based on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the entire whole,
+and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise the
+right to control the distribution of derivative or collective works based on the
+Program.
+
+In addition, mere aggregation of another work not based on the Program with the
+Program (or with a work based on the Program) on a volume of a storage or
+distribution medium does not bring the other work under the scope of this
+License.
+
+**3.** You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1 and 2
+above provided that you also do one of the following:
+
+*   **a)** Accompany it with the complete corresponding machine-readable source
+    code, which must be distributed under the terms of Sections 1 and 2 above on
+    a medium customarily used for software interchange; or,
+
+*   **b)** Accompany it with a written offer, valid for at least three years, to
+    give any third party, for a charge no more than your cost of physically
+    performing source distribution, a complete machine-readable copy of the
+    corresponding source code, to be distributed under the terms of Sections 1
+    and 2 above on a medium customarily used for software interchange; or,
+
+*   **c)** Accompany it with the information you received as to the offer to
+    distribute corresponding source code. (This alternative is allowed only for
+    noncommercial distribution and only if you received the program in object
+    code or executable form with such an offer, in accord with Subsection b
+    above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all the
+source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and installation
+of the executable. However, as a special exception, the source code distributed
+need not include anything that is normally distributed (in either source or
+binary form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component itself
+accompanies the executable.
+
+If distribution of executable or object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the source code
+from the same place counts as distribution of the source code, even though third
+parties are not compelled to copy the source along with the object code.
+
+**4.** You may not copy, modify, sublicense, or distribute the Program except as
+expressly provided under this License. Any attempt otherwise to copy, modify,
+sublicense or distribute the Program is void, and will automatically terminate
+your rights under this License. However, parties who have received copies, or
+rights, from you under this License will not have their licenses terminated so
+long as such parties remain in full compliance.
+
+**5.** You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Program or its derivative works. These actions are prohibited by law if you do
+not accept this License. Therefore, by modifying or distributing the Program (or
+any work based on the Program), you indicate your acceptance of this License to
+do so, and all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+**6.** Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these terms and
+conditions. You may not impose any further restrictions on the recipients'
+exercise of the rights granted herein. You are not responsible for enforcing
+compliance by third parties to this License.
+
+**7.** If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues), conditions
+are imposed on you (whether by court order, agreement or otherwise) that
+contradict the conditions of this License, they do not excuse you from the
+conditions of this License. If you cannot distribute so as to satisfy
+simultaneously your obligations under this License and any other pertinent
+obligations, then as a consequence you may not distribute the Program at all.
+For example, if a patent license would not permit royalty-free redistribution of
+the Program by all those who receive copies directly or indirectly through you,
+then the only way you could satisfy both it and this License would be to refrain
+entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply and the
+section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or
+other property right claims or to contest validity of any such claims; this
+section has the sole purpose of protecting the integrity of the free software
+distribution system, which is implemented by public license practices. Many
+people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose that
+choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+**8.** If the distribution and/or use of the Program is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Program under this License may add an explicit
+geographical distribution limitation excluding those countries, so that
+distribution is permitted only in or among countries not thus excluded. In such
+case, this License incorporates the limitation as if written in the body of this
+License.
+
+**9.** The Free Software Foundation may publish revised and/or new versions of
+the General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that version
+or of any later version published by the Free Software Foundation. If the
+Program does not specify a version number of this License, you may choose any
+version ever published by the Free Software Foundation.
+
+**10.** If you wish to incorporate parts of the Program into other free programs
+whose distribution conditions are different, write to the author to ask for
+permission. For software which is copyrighted by the Free Software Foundation,
+write to the Free Software Foundation; we sometimes make exceptions for this.
+Our decision will be guided by the two goals of preserving the free status of
+all derivatives of our free software and of promoting the sharing and reuse of
+software generally.
+
+
+No Warranty
+-----------
+
+**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
+"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
+PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+**12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
+BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
+OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

+NRPE With SSL/TLS
+=================
+
+This document covers the different methods of SSL transport
+that NRPE allows for. 
+
+If there was a TL;DR here, it is these:
+
+### Don't use NRPE without encryption
+
+and
+
+### Use Public Key Encryption
+
+Contents

+

+2. [NRPE Changes](#nrpe-changes)
+3. [check_nrpe Changes](#check_nrpe-changes)
+4. [Certificate Generation Example](#certificate-generation-example)
+
+
+Introduction
+------------
+
+NRPE has had basic support for SSL/TLS for some time now, but it was
+severely lacking. It only allowed anonymous Diffie Hellman (ADH) key
+exchange, it used a fixed 512-bit key (generated at `./configure`
+time and extremely insecure) and originally allowed SSLv2. In 2004,
+SSLv2 and SSLv3 support was disabled.
+
+`nrpe` and `check_nrpe` have been updated to offer much more secure
+encryption and more options. And the updates are done in a backward-
+compatible way, allowing you to migrate to the newer versions
+without having to do it all at once, and possibly miss updating some
+machines, causing lost reporting.
+
+
+
+NRPE Changes
+------------
+
+Running `./configure` will now create a 2048-bit DH key instead
+of the old 512-bit key. The most current versions of openSSL will
+still not allow it. In my testing, openSSL 1.0.1e allowed DH keys
+of 512 bits, and 1.0.1k would not allow 2048 bit keys. In addition
+we now call `SSL_CTX_set_options(ctx, SSL_OP_SINGLE_DH_USE)` so a
+new key is generated on each connection, based on the 2048-bit
+key generated.
+
+The NRPE configuration file has added new SSL/TLS options. The
+defaults currently will allow old check_nrpe plugins to continue to
+connect to the nrpe daemon, but can report on "old style"
+connections, or enforce more secure communication as your migration
+progresses. The new options are in the "SSL/TLS OPTIONS" section of
+nrpe.cfg, about two-thirds of the way down.
+
+If you are upgrading NRPE from a prior version, you can run the
+`update-cfg.pl` script to add the new parameters to your nrpe.cfg.
+
+The `ssl_version` directive lets you set which versions of SSL/TLS
+you want to allow. SSLv2, SSLv3, TLSv1, TLSv1.1 and TLSv1.2 are
+allowed, or those litereals with a `+` after them (as in TLSv1.1+).
+Without the `+`, *that version only* will be used. With the `+`,
+that *version or above* will be used. openSSL will always negotiate
+the highest available allowed version available on both ends. This
+directive currently defaults to `TLSv1+`.
+
+The `ssl_use_adh` directive is **DEPRECATED**, even though it is new.
+Possible values are `0` to not allow ADH at all, `1` to allow ADH,
+and `2` to require ADH. The `2` should never be required, but it's
+there just in case it's needed, for whatever reason. `1` is currently
+the default, which allows older `check_nrpe` plugins to connect using
+ADH. When all the plugins are migrated to the newer version, it
+should be set to `0`. In an upcoming version of NRPE, ADH will no
+longer be allowed at all. Note that if you use a `2` here, NRPE will
+override any `ssl_cipher_list` entries (below) to *only* allow ADH.
+
+The `ssl_cipher_list` directive lets you specify which ciphers you
+want to allow. It currently defaults to `ALL:!MD5:@STRENGTH` but can
+take any value allowed by openSSL. In an upcoming version of NRPE, it
+will be changed to something more secure, something like
+`ALL:!aNULL:!eNULL:!SSLv2:!LOW:!EXP:!RC4:!MD5:@STRENGTH`. Note that
+if you have `ssl_use_adh=2`, this string will be overridden with
+`ADH` which only only allow ADH.
+
+The `ssl_cacert_file`, `ssl_cert_file` and `ssl_privatekey_file`
+directives are used to specify which *.pem files are to be used for
+Public-Key Encryption (PKE). Setting these will allow clients to use
+PKE to communicate with the server, similar to how the HTTPS
+protocol works.
+
+The `ssl_client_certs` directive specifies whether or not a client
+certificate will be requested when a client tries to connect. A value
+of `0` means the nrpe daemon will not ask for or require a client
+certificate. A `1` will cause it to ask for a client certificate, but
+not require one. A `2` will require the client to present a valid
+certificate. This currently defaults to `0`. If you want to use
+client certificates and are upgrading the clients over time, you can
+set this to `1` once many have been upgraded, then set to `2` to
+force the use of client certs. Note that the client certs _must_ be
+signed by the CA cert specified in the `ssl_cacert_file` directive.
+
+The `ssl_logging` directive allows you to log some additional data
+to syslog. OR (or add) values together to have more than one option
+enabled. Values are `0` for no additional logging (the default),
+`1` to log startup SSL/TLS parameters from the nrpe.cfg file, `2` to
+log the SSL/TLS version of connections, `4` to log which cipher is
+being used for the connection, `8` to log if the plugin has a cert, and
+`16` to log details of plugin's certificate. `-1` will enable all.
+This can be especially helpful during plugin migration, so you can
+tell which plugins have certificates, what SSL/TLS version is being
+used, and which ciphers are being used.
+
+
+check_nrpe Changes
+------------------
+
+The `check_nrpe` plugin has also been updated to provide more secure
+encryption and allow the use of client certificates. The command line
+has several new options, which are outlined below. Both the long and
+short arguments are presented.
+
+`--no-adh` or `-d` will disable the use of ADH. This option is
+**DEPRECATED**, even though it's new. It will be removed in a
+future version.
+
+`--ssl-version=<ver>` or `-S <ver>` specifies minimum SSL/TLS version
+to use. See the `ssl_version` directive above for possible values.
+
+`--cipher-list=<value.` or `-L <value>` determines which ciphers will
+and won't be allowed. See the `ssl_cipher_list` directive above.
+
+`--client-cert=<path>` or `-C <path>` specifies an optional client
+certificate to use. If this value is entered, the next one below is
+required.
+
+`--key-file=<path>` or `-K <path>` specifies the client certificate
+key file to use. This goes along with `--client-cert` above.
+
+`--ca-cert-file=<path>` or `-A <path>` specifies the CA certificate
+to use in order to validate the nrpe daemon's public key.
+
+`--no-adh` or `-d` is **DEPRECATED**
+
+`--use-adh` or `-d [num]` is **DEPRECATED**, even though it is new.
+If you use `-d` or `-d 0` it acts the same way as as the old `-d`.
+Otherwise, use `1` to allow ADH, and `2` to require ADH.
+
+`--ssl-logging=<num>` or `-s <num>` allows you to log some additional
+data to syslog. OR (or add) values together to have more than one
+option enabled. See the description of the `ssl_logging` directive
+from NRPE above.
+
+
+
+Certificate Generation Example
+------------------------------
+
+**Note** _The following example does not follow best practice for
+creating and running a CA or creating certificates. It is for testing
+or possibly for use in a small environment. Sloppy security is as bad
+as no security._
+
+In this example, we are going to put everything in the
+`/usr/local/nagios/etc/ssl` directory. You may want to use the more
+common `/etc/ssl` directory, or somewhere else entirely.
+
+We are going to assume your company name is Foo Widgets, LLC; the
+server running the nagios process (and thus the check_nrpe program)
+is called `nag_serv`; and there are two Linux machines that will
+run the nrpe daemon: `db_server` and `bobs_workstation`.
+
+
+#### Set up the directories
+
+As root, do the following:
+
+        mkdir -p -m 750 /usr/local/nagios/etc/ssl
+        chown root:nagios /usr/local/nagios/etc/ssl
+        cd /usr/local/nagios/etc/ssl
+        mkdir -m 750 ca
+        chown root:root ca
+        mkdir -m 750 server_certs
+        chown root:nagios server_certs
+        mkdir -m 750 client_certs
+        chown root:nagios client_certs
+
+
+#### Create Certificate Authority
+
+If you want to validate client or server certificates, you will need
+to create a Certificate Authority (CA) that will sign all client and
+server certificates. If your organization already has a CA, you can
+use that.
+
+As root, do the following:
+
+        cd /usr/local/nagios/etc/ssl/ca
+        openssl req -x509 -newkey rsa:4096 -keyout ca_key.pem \
+           -out ca_cert.pem -utf8 -days 3650
+
+When asked, enter a passphrase. Then follow the prompts. You will
+probably want to include `CA` or `Certificate Authority` in for
+`Organizational Unit Name` and `Common Name`. For example:
+
+        Organization Name (eg, company) []:Foo Widgets LLC
+        Organizational Unit Name (eg, section) []:Foo Certificate Authority
+        Common Name (e.g. server FQDN or YOUR name) []:Foo Nagios CA
+
+
+#### Create NRPE Server Certificate Requests
+
+For each of the hosts that will be running the nrpe daemon, you will
+need a server certificate. You can create a key, and the CSR
+(Certificate Signing Request) separately, but the following commands
+will do both with one command. As root, do the following:
+
+        cd /usr/local/nagios/etc/ssl/server_certs
+        openssl req -new -newkey rsa:2048 -keyout db_server.key \
+           -out db_server.csr -nodes
+        openssl req -new -newkey rsa:2048 -keyout bobs_workstation.key \
+           -out bobs_workstation.csr -nodes
+
+Follow the prompts. The `-nodes` at the end of the lines tells
+openssl to generate the key without a passphrase. Leave it off if you
+want someone to enter a passphrase whenever the machine boots.
+
+Now you need to sign the CSRs with your CA key.
+
+If you have the default `/etc/openssl.cnf`, either change it, or as root, do:
+
+        cd /usr/local/nagios/etc/ssl
+        mkdir demoCA
+        mkdir demoCA/newcerts
+        touch demoCA/index.txt
+        echo "01" > demoCA/serial
+        chown -R root:root demoCA
+        chmod 700 demoCA
+        chmod 700 demoCA/newcerts
+        chmod 600 demoCA/serial
+        chmod 600 demoCA/index.txt
+
+Now, sign the CSRs. As root, do the following:
+
+        cd /usr/local/nagios/etc/ssl
+        openssl ca -days 365 -notext -md sha256 \
+           -keyfile ca/ca_key.pem -cert ca/ca_cert.pem \
+           -in server_certs/db_server.csr \
+           -out server_certs/db_server.pem
+        chown root:nagios server_certs/db_server.pem
+        chmod 440 server_certs/db_server.pem
+        openssl ca -days 365 -notext -md sha256 \
+           -keyfile ca/ca_key.pem -cert ca/ca_cert.pem \
+           -in server_certs/bobs_workstation.csr \
+           -out server_certs/bobs_workstation.pem
+        chown root:nagios server_certs/bobs_workstation.pem
+        chmod 440 server_certs/bobs_workstation.pem
+
+Now, copy the `db_server.pem` and `db_server.key` files to the
+db_server machine, and the `bobs_workstation.pem` and
+`bobs_workstation.key` files to bobs_workstation. Copy the
+`ca/ca_cert.pem` file to both machines.
+
+
+#### Create NRPE Client Certificate Requests
+
+Now you need to do the same thing for the machine that will be
+running the check_nrpe program.
+
+        cd /usr/local/nagios/etc/ssl/client_certs
+        openssl req -new -newkey rsa:2048 -keyout nag_serv.key \
+           -out nag_serv.csr -nodes
+
+        cd /usr/local/nagios/etc/ssl
+        openssl ca -extensions usr_cert -days 365 -notext -md sha256 \
+           -keyfile ca/ca_key.pem -cert ca/ca_cert.pem \
+           -in client_certs/nag_serv.csr \
+           -out client_certs/nag_serv.pem
+        chown root:nagios client_certs/nag_serv.pem
+        chmod 440 client_certs/nag_serv.pem
+
+Now, copy the `nag_serv.pem`, `nag_serv.key` and `ca/ca_cert.pem`
+files to the nag_serv machine, if you did the above on a different
+computer.
+
+Put the location of each computers' three files in the `nrpe.cfg`
+file or in the check_nrpe command line. You should now have
+encryption and, if desired, key validation.

+Nagios Remote Plugin Executor (NRPE)
+====================================
+
+For installation instructions and information on the design overview
+of the NRPE addon, please read the PDF documentation that is found in
+this directory: `docs/NRPE.pdf`.
+
+If you are upgrading from a previous version, you'll want to
+check the [Changelog](CHANGELOG.md) and then run `./update-cfg.pl` to
+add the new SSL parameters to your config file.
+
+TL;DR: You can jump straight to [Compiling](#compiling) and
+[Installing](#installing)
+
+You'll want to read up on the [Security](SECURITY.md) document
+regarding NRPE, no doubt.
+
+And make sure to check out the [SSL Readme](README.SSL.md) as well,
+if you plan on using encryption methods to transmit `nrpe` data.
+
+
+Purpose
+-------
+The purpose of this addon is to allow you to execute Nagios
+plugins on a remote host in as transparent a manner as possible.
+
+
+Contents
+--------
+
+There are two pieces to this addon:
+
+1. `nrpe`
+
+   This program runs as a background process on the
+   remote host and processes command execution requests
+   from the check_nrpe plugin on the Nagios host.
+   Upon receiving a plugin request from an authorized
+   host, it will execute the command line associated
+   with the command name it received and send the
+   program output and return code back to the
+   check_nrpe plugin
+
+2. `check_nrpe` 
+
+   This is a plugin that is run on the Nagios host
+   and is used to contact the NRPE process on remote
+   hosts.  The plugin requests that a plugin be
+   executed on the remote host and wait for the NRPE
+   process to execute the plugin and return the result.
+   The plugin then uses the output and return code
+   from the plugin execution on the remote host for
+   its own output and return code.
+
+
+Compiling
+---------
+
+If you are having any problems compiling on your system, 
+please let us know (preferrably with fixes). Most users 
+should be able to compile `nrpe` and the `check_nrpe` 
+plugin with the following commands...
+
+    ./configure
+    make all
+
+***HINT:*** `./configure --help`
+
+**NOTE:** If you're cloning from GitHub, you'll need to run
+`autoconf` first.
+
+**NOTE:** Since the check_nrpe plugin and nrpe daemon run 
+on different machines (the plugin runs on the Nagios host and 
+the daemon runs on the remote host), you will have to compile 
+the nrpe daemon on the target machine.
+
+
+Installing
+----------
+
+You have a few options here. The binaries created from `make all` 
+were placed in your `src/` directory. You can either copy these 
+where they need to be, or you can run any of the following 
+`make install` options:
+
+* `make install-groups-users`
+
+   Add the users and groups sepcified during `./configure`. Defaults
+   to nagios and nagios, respectively. You can override these with the
+   `./configure --with-nrpe-user=USER --with-nrpe-group=GROUP`.
+
+* `make install`
+
+   This will run both `install-plugin` and `install-daemon`.
+
+* `make install-plugin`
+
+   This will install the plugin by default in 
+   `/usr/local/nagios/libexec`. You can override this 
+   behavior by using the `--with-pluginsdir=DIR` flag during
+   `./configure`.
+
+* `make install-daemon`
+
+   This will install the plugin by default in 
+   `/usr/local/nagios/bin`. You can override this 
+   behavior by using the `--prefix=DIR` or 
+   `--bindir=DIR` flags during `./configure`.
+
+* `make install-config`
+
+   This will install the sample config by default in 
+   `/usr/local/nagios/etc`. You can override this 
+   behavior by using the `--with-pkgsysconfdir=DIR` 
+   flag during `./configure`.
+
+* `make install-inetd`
+
+   `./configure` attempts to determine your inetd type.
+   If it finds it, it will install the appropriate inetd 
+   script in the proper location. You can help it out with
+   `./configure --with-inetd-type=TYPE` where `TYPE` can be
+   one of: `inetd`, `xinetd`, `systemd`, `launchd`, 
+   `smf10`, `smf11`.
+
+* `make install-init`
+
+   `./configure` attempts to determine the appropriate
+   init type. If it figures it out, will install the
+   required startup script. You can help it out with
+   `./configure --with-init-type=TYPE` where TYPE can be
+   one of: `bsd`, `sysv`, `systemd`, `launchd`, `smf10`, 
+   `smf11`, `upstart`, `openrc`.
+
+If you used all the necessary `./configure` flags, you shouldn't
+need to tweak your config file any at this point, and a simple
+`service nrpe start` or `systemctl start nrpe.service` should
+work just fine.
+
+Configuring
+-----------
+
+A sample config file for the NRPE daemon are located in the
+`sample-config/` subdirectory.
+
+If you used the proper flags during `./configure`, this file
+should contain all of the appropriate information as a starting
+point.
+
+
+Running Under `inetd` or `xinetd`
+---------------------------------
+
+If you plan on running nrpe under inetd or xinetd and making use
+of TCP wrappers, you need to add a line to your `/etc/services`
+file as follows (modify the port number as you see fit)
+
+    nrpe            5666/tcp    # NRPE
+
+The run `make install-inetd` to copy the appropriate file, or
+add the appropriate line to your `/etc/inetd.conf`.
+
+**NOTE:** If you run nrpe under inetd or xinetd, the server_port
+and allowed_hosts variables in the nrpe configuration file are
+ignored.
+
+
+* `inetd`
+
+   After running `make install-inetd`, your `/etc/inetd.conf` file will
+   contain lines similar to the following:
+
+       # Enable the following entry to enable the nrpe daemon
+       #nrpe stream tcp nowait nagios /usr/local/nagios/bin/nrpe nrpe -c /usr/local/nagios/etc/nr
+       # Enable the following entry if the nrpe daemon didn't link with libwrap
+       #nrpe stream tcp nowait nagios /usr/sbin/tcpd /usr/local/nagios/bin/nrpe -c /usr/local/nag
+
+   Un-comment the appropriate line, then Restart inetd:
+
+      /etc/rc.d/init.d/inet restart
+
+   OpenBSD users can use the following command to restart inetd:
+
+      kill -HUP `cat /var/run/inet.pid`
+
+   Then add entries to your `/etc/hosts.allow` and `/etc/hosts.deny`
+   file to enable TCP wrapper protection for the nrpe service.
+   This is optional, although highly recommended.
+
+
+* `xinetd`
+
+   If your system uses xinetd instead of inetd, `make install-inetd`
+   will create a file called `nrpe` in your `/etc/xinetd.d`

+   * Replace the `127.0.0.1` field with the IP addresses of hosts which
+     are allowed to connect to the NRPE daemon.  This only works if xinetd was
+     compiled with support for tcpwrappers.
+   * Add entries to your `/etc/hosts.allow` and `/etc/hosts.deny`
+     file to enable TCP wrapper protection for the nrpe service.
+     This is optional, although highly recommended.
+
+   * Restart xinetd:
+
+         /etc/rc.d/init.d/xinetd restart
+
+
+Configuring Things On The Nagios Host
+---------------------------------------
+
+Examples for configuring the nrpe daemon are found in the sample
+`nrpe.cfg` file included in this distribution.  That config file
+resides on the remote host(s) along with the nrpe daemon.  The
+check_nrpe plugin gets installed on the Nagios host.  In order
+to use the check_nrpe plugin from within Nagios, you will have
+to define a few things in the host config file.  An example
+command definition for the check_nrpe plugin would look like this:
+
+    define command{
+        command_name           check_nrpe
+        command_line           /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
+        }
+
+In any service definitions that use the nrpe plugin/daemon to
+get their results, you would set the service check command portion
+of the definition to something like this (sample service definition
+is simplified for this example):
+
+    define service{
+        host_name              someremotehost
+        service_description    someremoteservice
+        check_command          check_nrpe!yourcommand
+        ... etc ...
+        }
+
+where `yourcommand` is a name of a command that you define in
+your `nrpe.cfg` file on the remote host (see the docs in the
+sample nrpe.cfg file for more information).

+NRPE SECURITY README
+====================
+
+TCP Wrapper Support
+-------------------
+
+NRPE 2.x includes native support for TCP wrappers. Once you
+compile NRPE you can check to see if it has wrapper support
+built in by running the daemon from the command line without
+any arguments like this:
+
+    ./nrpe --help
+
+
+Command Arguments
+-----------------
+
+NRPE 2.0 includes the ability for clients to supply arguments to
+commands which should be run.  Please note that this feature
+should be considered a security risk, and you should only use
+it if you know what you're doing!
+
+
+Bash Command Substitution
+-------------------------
+
+Even with the metacharacter restrictions below, if command arguments 
+are enabled, it is still possible to send bash command substitutions 
+in the form `$(...)` as an argument. This is explicitly disabled by 
+default, but can be enabled by a configure-time option and a
+configuration file option. Enabling this option is **VERY RISKY**
+and its use is **HIGHLY DISCOURAGED**.
+
+
+Enabling Arguments
+------------------
+
+To enable support for command argument in the daemon, you must
+do two things:
+
+   1.  Run the configure script with the `--enable-command-args`
+       option
+
+   2.  Set the `dont_blame_nrpe` directive in the NRPE config
+       file to `1`.
+
+
+Enabling Bash Command Substitution
+----------------------------------
+
+To enable support for arguments containing bash command substitutions, 
+you must do two things:
+
+   1.  Enable arguments as described above
+
+   2.  Include the `--enable-bash-command-substitution` configure
+       option when running the configure script
+
+   3.  Set the `allow_bash_command_substitutions` directive in the 
+       NRPE config file to `1`.
+
+
+Nasty Metacharacters
+--------------------
+
+To help prevent some nasty things from being done by evil 
+clients, the following metacharacters are not allowed
+in client command arguments:
+
+    | ` & > < ' \ [ ] { } ; ! \r \n
+
+You can override these defaults by adjusting the `nasty_metachars`
+flag in the config file.
+
+Any client request which contains the above mentioned metachars
+is discarded.
+
+
+User/Group Restrictions
+-----------------------
+
+The NRPE daemon cannot be run with (effective) root user/group
+privileges.  You must run the daemon with an account that does
+not have superuser rights.  Use the `--with-nrpe-user` and 
+`--with-nrpe-group` flags during `./configure`, or the `nrpe_user`
+and `nrpe_group` config file options to specify which user/group 
+the daemon should run as.
+
+
+Encryption
+----------
+
+If you do enable support for command arguments in the NRPE daemon,
+make sure that you encrypt communications either by using:
+
+   1.  Stunnel (see http://www.stunnel.org for more info)
+   2.  Native SSL support (See the [SSL Readme](README.SSL.md) file for more info)
+
+Do **NOT** assume that just because the daemon is behind a firewall
+that you are safe! ***Always encrypt NRPE traffic!***
+
+
+Using Arguments
+---------------
+
+How do you use command arguments?  Well, lets say you define a
+command in the NRPE config file that looks like this:
+
+    command[check_users]=/usr/local/nagios/libexec/check_users -w $ARG1$ -c $ARG2$
+
+You could then call the check_nrpe plugin like this:
+
+    ./check_nrpe -H <host> -c check_users -a 5 10
+
+The arguments '5' and '10' get substituted into the appropriate
+`$ARGx$` macros in the command (`$ARG1$` and `$ARG2$`, respectively).
+The command that would be executed by the NRPE daemon would look
+like this:
+
+    /usr/local/nagios/libexec/check_users -w 5 -c 10
+
+You can supply up to 16 arguments to be passed to the command
+for substitution in `$ARG$` macros (`$ARG1$` - `$ARG16$`).

+            [this package]) to adapt to many kinds of systems.
+
+Usage: $[0] [[OPTION]]... [[VAR=VALUE]]...
+
+[To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'

+\`configure' configures nrpe newdate to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [/usr/local/nagios]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`/usr/local/nagios/bin', \`/usr/local/nagios/lib' etc.  You can specify
+an installation prefix other than \`/usr/local/nagios' using \`--prefix',
+for instance \`--prefix=$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR        plugins, brokers, CGI [EPREFIX/libexec]
+  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           r/o arch.-independent data [DATAROOTDIR/PKG_NAME]
+  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]

+Optional Features:

+  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
+  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]

+                          default) will install to /usr/local/nagios, 'os'
+                          will try to determine which method to use based on
+                          OS type and distribution. Fine tuning using the
+                          '--bindir', etc. overrides above will still work
+  --enable-showdirs-only=yes
+                          This option will cause 'configure' to stop after
+                          determining the install locations based on
+                          '--enable-install-method', so you can see the
+                          destinations before a full './configure', 'make',
+                          'make install' process.
+  --disable-tcpd          disables support for tcpd even if present
+  --disable-ssl           disables native SSL support [default=check]
+  --enable-command-args   allows clients to specify command arguments. ***
+                          THIS IS A SECURITY RISK! *** Read the SECURITY file
+                          before using this option!
+  --enable-bash-command-substitution
+                          allows clients to pass bash command substitutions of
+                          the form $(command). *** THIS IS A HIGH SECURITY
+                          RISK! *** Read the SECURITY file before using this

+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
+  --with-opsys=OS         specify operating system (linux, osx, bsd, solaris,

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+NOTES:
+------
+
+The service definition below assumes you have a command called "check_tcp" already setup
+in your config files.
+
+The command definition below assumes that the $USER1$ macro is used to define the location
+of your Nagios plugins (i.e. "/usr/local/nagios/libexec") and that the nrpe_check_control
+service is located in that directory.
+
+
+
+SAMPLE CONFIG FILE SNIPPETS:
+----------------------------
+
+define service {
+	host_name	<host name goes here>
+	description	NRPE
+	...
+	event_handler	nrpe_check_control
+	check_command	check_tcp!-p 5666
+        }
+
+define command {
+	command_name	nrpe_check_control
+	command_line	$USER1$/nrpe_check_control $SERVICESTATE$ $SERVICESTATETYPE$ $SERVICEATTEMPT$ "$HOSTNAME$"
+	}
+
+
+
+
+ORIGINAL EMAIL SNIPPET: 
+-----------------------
+
+Date sent:      	Fri, 30 Mar 2001 18:51:48 -0500
+From:           	adam.bowen@<>
+Subject:        	Event Handler
+To:             	[nagios@nagios.org]
+
+I am attaching the source code for an event handler I wrote to 
+control checks using nrpe.  I add the following check to all remote hosts
+using nrpe:
+
+<see example above>
+
+I added this line to the commands.cfg file:
+
+<see example above>
+
+When the NRPE service check listed above has 3 failed connection
+attempts, it will run the nrpe_check_control which will search the
+services file for all services for $HOSTNAME$ that use the check_nrpe.
+
+It will then request that all these services be disabled.  When the
+NRPE check returns to the OK state, it will request that all services
+using check_nrpe be re-enabled. This will prevent unnecessary e-mail
+when there is a problem with the NRPE daemon.  This does require 
+that external commands be enabled.
+
+(See attached file: nrpe_check_control.c)
+
+I thought some other [Nagios] users might find this useful.
+

+The GNU General Public License, Version 2, June 1991 (GPLv2)
+============================================================
+
+> Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+> 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+
+Preamble
+--------
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to most
+of the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software is
+covered by the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom to
+distribute copies of free software (and charge for this service if you wish),
+that you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs; and that you know you can
+do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to deny
+you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of the
+software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for a
+fee, you must give the recipients all the rights that you have. You must make
+sure that they, too, receive or can get the source code. And you must show them
+these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2) offer
+you this license which gives you legal permission to copy, distribute and/or
+modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients to
+know that what they have is not the original, so that any problems introduced by
+others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We wish
+to avoid the danger that redistributors of a free program will individually
+obtain patent licenses, in effect making the program proprietary. To prevent
+this, we have made it clear that any patent must be licensed for everyone's free
+use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+
+Terms And Conditions For Copying, Distribution And Modification
+---------------------------------------------------------------
+
+**0.** This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms of
+this General Public License. The "Program", below, refers to any such program or
+work, and a "work based on the Program" means either the Program or any
+derivative work under copyright law: that is to say, a work containing the
+Program or a portion of it, either verbatim or with modifications and/or
+translated into another language. (Hereinafter, translation is included without
+limitation in the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered by
+this License; they are outside its scope. The act of running the Program is not
+restricted, and the output from the Program is covered only if its contents
+constitute a work based on the Program (independent of having been made by
+running the Program). Whether that is true depends on what the Program does.
+
+**1.** You may copy and distribute verbatim copies of the Program's source code
+as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this License
+and to the absence of any warranty; and give any other recipients of the Program
+a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you may at
+your option offer warranty protection in exchange for a fee.
+
+**2.** You may modify your copy or copies of the Program or any portion of it,
+thus forming a work based on the Program, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that you also
+meet all of these conditions:
+
+*   **a)** You must cause the modified files to carry prominent notices stating
+    that you changed the files and the date of any change.
+
+*   **b)** You must cause any work that you distribute or publish, that in whole
+    or in part contains or is derived from the Program or any part thereof, to
+    be licensed as a whole at no charge to all third parties under the terms of
+    this License.
+
+*   **c)** If the modified program normally reads commands interactively when
+    run, you must cause it, when started running for such interactive use in the
+    most ordinary way, to print or display an announcement including an
+    appropriate copyright notice and a notice that there is no warranty (or
+    else, saying that you provide a warranty) and that users may redistribute
+    the program under these conditions, and telling the user how to view a copy
+    of this License. (Exception: if the Program itself is interactive but does
+    not normally print such an announcement, your work based on the Program is
+    not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be reasonably
+considered independent and separate works in themselves, then this License, and
+its terms, do not apply to those sections when you distribute them as separate
+works. But when you distribute the same sections as part of a whole which is a
+work based on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the entire whole,
+and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise the
+right to control the distribution of derivative or collective works based on the
+Program.
+
+In addition, mere aggregation of another work not based on the Program with the
+Program (or with a work based on the Program) on a volume of a storage or
+distribution medium does not bring the other work under the scope of this
+License.
+
+**3.** You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1 and 2
+above provided that you also do one of the following:
+
+*   **a)** Accompany it with the complete corresponding machine-readable source
+    code, which must be distributed under the terms of Sections 1 and 2 above on
+    a medium customarily used for software interchange; or,
+
+*   **b)** Accompany it with a written offer, valid for at least three years, to
+    give any third party, for a charge no more than your cost of physically
+    performing source distribution, a complete machine-readable copy of the
+    corresponding source code, to be distributed under the terms of Sections 1
+    and 2 above on a medium customarily used for software interchange; or,
+
+*   **c)** Accompany it with the information you received as to the offer to
+    distribute corresponding source code. (This alternative is allowed only for
+    noncommercial distribution and only if you received the program in object
+    code or executable form with such an offer, in accord with Subsection b
+    above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all the
+source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and installation
+of the executable. However, as a special exception, the source code distributed
+need not include anything that is normally distributed (in either source or
+binary form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component itself
+accompanies the executable.
+
+If distribution of executable or object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the source code
+from the same place counts as distribution of the source code, even though third
+parties are not compelled to copy the source along with the object code.
+
+**4.** You may not copy, modify, sublicense, or distribute the Program except as
+expressly provided under this License. Any attempt otherwise to copy, modify,
+sublicense or distribute the Program is void, and will automatically terminate
+your rights under this License. However, parties who have received copies, or
+rights, from you under this License will not have their licenses terminated so
+long as such parties remain in full compliance.
+
+**5.** You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Program or its derivative works. These actions are prohibited by law if you do
+not accept this License. Therefore, by modifying or distributing the Program (or
+any work based on the Program), you indicate your acceptance of this License to
+do so, and all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+**6.** Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these terms and
+conditions. You may not impose any further restrictions on the recipients'
+exercise of the rights granted herein. You are not responsible for enforcing
+compliance by third parties to this License.
+
+**7.** If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues), conditions
+are imposed on you (whether by court order, agreement or otherwise) that
+contradict the conditions of this License, they do not excuse you from the
+conditions of this License. If you cannot distribute so as to satisfy
+simultaneously your obligations under this License and any other pertinent
+obligations, then as a consequence you may not distribute the Program at all.
+For example, if a patent license would not permit royalty-free redistribution of
+the Program by all those who receive copies directly or indirectly through you,
+then the only way you could satisfy both it and this License would be to refrain
+entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply and the
+section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or
+other property right claims or to contest validity of any such claims; this
+section has the sole purpose of protecting the integrity of the free software
+distribution system, which is implemented by public license practices. Many
+people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose that
+choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+**8.** If the distribution and/or use of the Program is restricted in certain
+countries either by patents or by copyrighted interfaces, the original copyright
+holder who places the Program under this License may add an explicit
+geographical distribution limitation excluding those countries, so that
+distribution is permitted only in or among countries not thus excluded. In such
+case, this License incorporates the limitation as if written in the body of this
+License.
+
+**9.** The Free Software Foundation may publish revised and/or new versions of
+the General Public License from time to time. Such new versions will be similar
+in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies
+a version number of this License which applies to it and "any later version",
+you have the option of following the terms and conditions either of that version
+or of any later version published by the Free Software Foundation. If the
+Program does not specify a version number of this License, you may choose any
+version ever published by the Free Software Foundation.
+
+**10.** If you wish to incorporate parts of the Program into other free programs
+whose distribution conditions are different, write to the author to ask for
+permission. For software which is copyrighted by the Free Software Foundation,
+write to the Free Software Foundation; we sometimes make exceptions for this.
+Our decision will be guided by the two goals of preserving the free status of
+all derivatives of our free software and of promoting the sharing and reuse of
+software generally.
+
+
+No Warranty
+-----------
+
+**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
+"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
+PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+**12.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR

+autoconf-macros
+===============
+
+The purpose of Nagios autoconf-macros is to have a central place for
+autoconf macros that can be maintained in one place, but be used by any
+of the Nagios software. It is intended to be used as a git subtree.
+See the [Usage](#usage) and [References](#references) sections below.
+
+Since this project will be included in several parent projects, any
+changes must be as project-neutral as possible.
+
+Make sure to check out the [CHANGELOG](CHANGELOG.md) for relevant 
+information, as well.
+
+
+Contents
+--------
+
+The collection consists of the following macros:
+
+### AX_NAGIOS_GET_OS alias AC_NAGIOS_GET_OS
+
+> Output Variable : `opsys`
+
+This macro detects the operating system, and transforms it into a generic
+label. The most common OS's that use Nagios software are recognized and
+used in subsequent macros.
+
+### AX_NAGIOS_GET_DISTRIB_TYPE alias AC_NAGIOS_GET_DISTRIB_TYPE
+
+> Output Variables : `dist_type`, `dist_ver`
+
+This macro detects the distribution type. For Linux, this would be rh
+(for Red Hat and derivitives), suse (OpenSUSE, SLES, derivitives), gentoo
+(Gentoo and derivitives), debian (Debian and derivitives), and so on.
+For BSD, this would be openbsd, netbsd, freebsd, dragonfly, etc. It can
+also be aix, solaris, osx, and so on for Unix operating systems.
+
+### AX_NAGIOS_GET_INIT alias AC_NAGIOS_GET_INIT
+
+> Output Variable : `init_type`
+
+This macro detects what software is used to start daemons on bootup
+or on request, generally knows as the "init system". The init_type
+will generally be one of sysv (many), bsd (Slackware), newbsd (*BSD),
+launchd (OS X), smf10 or smf11 (Solaris), systemd (newer Linux),
+gentoo (older Gentoo), upstart (several), or unknown.
+
+### AX_NAGIOS_GET_INETD alias AC_NAGIOS_GET_INETD
+
+> Output Variable : `inetd_type`
+
+This macro detects what software is used to start daemons or services
+on demand, which historically has been "inetd". The inetd_type
+will generally be one of inetd, xinetd, launchd (OS X), smf10 or smf11
+(Solaris), systemd (newer Linux), upstart (several), or unknown.
+
+### AX_NAGIOS_GET_PATHS alias AC_NAGIOS_GET_PATHS
+
+> Output Variables : **many!**
+
+This macro determines the installation paths for binaries, config files,
+PID files, and so on. For a "standard" install of Nagios, NRPE, NDO Utils,
+etc., most will be in the /usr/local/nagios hierarchy with startup files
+located in /etc. For distributions or software repositories, the
+"--enable-install-method=os" option can be used. This will determine the
+O/S dependant directories, such as /usr/bin, /usr/sbin, /var/lib/nagios,
+/usr/lib/nagios, etc. or for OS X, /Library/LaunchDaemons.
+
+### AX_NAGIOS_GET_FILES alias AC_NAGIOS_GET_FILES
+
+> Output Variables : `src_init`, `src_inetd`, `src_tmpfile`
+
+Each Nagios project will have a top-level directory named "/startup/".
+In that directory will be "*.in" files for the various "init_type" and
+"inetd_type" systems. This macro will determine which file(s) from
+that directory will be needed.
+
+### AX_NAGIOS_GET_SSL alias AC_NAGIOS_GET_SSL
+
+> Output Variables : `HAVE_KRB5_H`, `HAVE_SSL`, `SSL_INC_DIR`, `SSL_LIB_DIR`, `CFLAGS`, `LDFLAGS`, `LIBS`
+
+This macro checks various directories for SSL libraries and header files.
+The searches are based on known install locations on various operating
+systems and distributions, for openssl, gnutls-openssl, and nss_compat_ossl.
+If it finds the headers and libraries, it will then do an `AC_LINK_IFELSE`
+on a simple program to make sure a compile and link will work correctly.
+
+
+Usage
+-----
+
+This repo is intended to be used as a git subtree, so changes will
+automatically propogate, and still be reasonably easy to use.
+
+* First, Create, checkout, clone, or branch your project. If you do an
+`ls -AF` it might look something like this:
+
+           .git/      .gitignore    ChangeLog   LICENSE   Makefile.in
+           README     configure.ac  include/    src/
+
+* Then make a reference to _this_ project inside your project.
+
+           git remote add autoconf-macros git@github.com:NagiosEnterprises/autoconf-macros
+           git subtree add --prefix=macros/ autoconf-macros master
+
+* After executing the above two commands, if you do an `ls -AF` now,
+it should look like this:
+
+           .git/      .gitignore    ChangeLog   LICENSE   Makefile.in
+           README     configure.ac  include/    macros/   src/
+
+* The `macros/` directory has been added.
+
+* Now do a `git push` to save everything.
+
+* If you make any changes to autoconf-macros, commit them separately
+from any parent-project changes to keep from polluting the commit
+history with unrelated comments.
+
+* To submit your changes to autoconf-macros:
+
+           git subtree push --prefix=macros autoconf-macros peters-updates
+This will create a new branch called `peters-updates`. You then need to
+create a _pull request_ to get your changes merged into autoconf-macros
+master.
+
+* To get the latest version of `autoconf-macros` into your parent project:
+
+           git subtgree pull --squash --prefix=macros autoconf-macros master
+
+
+References
+----------
+
+Now that autoconf-macros is available to your project, you will need to
+reference it.
+
+* Create (or add these lines to) file `YourProject/aclocal.m4`
+
+           m4_include([macros/ax_nagios_get_os])
+           m4_include([macros/ax_nagios_get_distrib])
+           m4_include([macros/ax_nagios_get_init])
+           m4_include([macros/ax_nagios_get_inetd])
+           m4_include([macros/ax_nagios_get_paths])
+           m4_include([macros/ax_nagios_get_files])
+           m4_include([macros/ax_nagios_get_ssl])
+
+* In your `YourProject/configure.ac` add the following lines. A good place
+to put them would be right after any `AC_PROG_*` entries:
+
+           AC_NAGIOS_GET_OS
+           AC_NAGIOS_GET_DISTRIB_TYPE
+           AC_NAGIOS_GET_INIT
+           AC_NAGIOS_GET_INETD
+           AC_NAGIOS_GET_PATHS
+           AC_NAGIOS_GET_FILES
+
+* If you need SSL functionality, add the following to `YourProject/configure.ac`
+where you want to check for SSL:
+
+           AC_NAGIOS_GET_SSL
+
+* You will now be able to reference any of the variables in `config.h.in`
+and any files listed in the `AC_CONFIG_FILES` macro in `configure.ac`.

+#
+# nagios          ALL=(ALL) NOPASSWD: /usr/lib/nagios/plugins/
+#
+# This lets the nagios user run all commands in that directory (and only them)

+# WEAK RANDOM SEED OPTION
+# This directive allows you to use SSL even if your system does not have

+# If an "or above" version is used, the best will be negotiated. So if both

+# If you are using openssl 1.1.0 or above, the SSLv2 options are not available.
+
+#ssl_version=SSLv2+

+# it will execute the command specified by the <command_line> argument.
+#
+# Unlike Nagios, the command line cannot contain macros - it must be
+# typed exactly as it should be executed.
+#
+# Note: Any plugins that are used in the command lines must reside
+# on the machine that this daemon is running on!  The examples below
+# assume that you have plugins installed in a /usr/local/nagios/libexec
+# directory.  Also note that you will have to modify the definitions below
+# to match the argument format the plugins expect.  Remember, these are
+# examples only!
+
+
+# The following examples use hardcoded command arguments...
+# This is by far the most secure method of using NRPE
+

+# command arguments *AND* the dont_blame_nrpe directive in this
+# config file is set to '1'.  This poses a potential security risk, so
+# make sure you read the SECURITY file before doing this.

+/**************************************************************
+ * Original:
+ * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
+ * A bombproof version of doprnt (dopr) included.
+ * Sigh.  This sort of thing is always nasty do deal with.  Note that
+ * the version here does not include floating point...
+ *
+ * snprintf() is used instead of sprintf() as it does limit checks
+ * for string length.  This covers a nasty loophole.
+ *
+ * The other functions are there to prevent NULL pointers from
+ * causing nast effects.
+ *
+ * More Recently:
+ *  Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
+ *  This was ugly.  It is still ugly.  I opted out of floating point
+ *  numbers, but the formatter understands just about everything
+ *  from the normal C string format, at least as far as I can tell from
+ *  the Solaris 2.5 printf(3S) man page.
+ *
+ *  Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
+ *    Ok, added some minimal floating point support, which means this
+ *    probably requires libm on most operating systems.  Don't yet
+ *    support the exponent (e,E) and sigfig (g,G).  Also, fmtint()
+ *    was pretty badly broken, it just wasn't being exercised in ways
+ *    which showed it, so that's been fixed.  Also, formated the code
+ *    to mutt conventions, and removed dead code left over from the
+ *    original.  Also, there is now a builtin-test, just compile with:
+ *           gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
+ *    and run snprintf for results.
+ * 
+ *  Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
+ *    The PGP code was using unsigned hexadecimal formats. 
+ *    Unfortunately, unsigned formats simply didn't work.
+ *
+ *  Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
+ *    The original code assumed that both snprintf() and vsnprintf() were
+ *    missing.  Some systems only have snprintf() but not vsnprintf(), so
+ *    the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ *  Andrew Tridgell (tridge@samba.org) Oct 1998
+ *    fixed handling of %.0f
+ *    added test for HAVE_LONG_DOUBLE
+ *
+ * tridge@samba.org, idra@samba.org, April 2001
+ *    got rid of fcvt code (twas buggy and made testing harder)
+ *    added C99 semantics
+ *
+ * date: 2002/12/19 19:56:31;  author: herb;  state: Exp;  lines: +2 -0
+ * actually print args for %g and %e
+ * 
+ * date: 2002/06/03 13:37:52;  author: jmcd;  state: Exp;  lines: +8 -0
+ * Since includes.h isn't included here, VA_COPY has to be defined here.  I don't
+ * see any include file that is guaranteed to be here, so I'm defining it
+ * locally.  Fixes AIX and Solaris builds.
+ * 
+ * date: 2002/06/03 03:07:24;  author: tridge;  state: Exp;  lines: +5 -13
+ * put the ifdef for HAVE_VA_COPY in one place rather than in lots of
+ * functions
+ * 
+ * date: 2002/05/17 14:51:22;  author: jmcd;  state: Exp;  lines: +21 -4
+ * Fix usage of va_list passed as an arg.  Use __va_copy before using it
+ * when it exists.
+ * 
+ * date: 2002/04/16 22:38:04;  author: idra;  state: Exp;  lines: +20 -14
+ * Fix incorrect zpadlen handling in fmtfp.
+ * Thanks to Ollie Oldham <ollie.oldham@metro-optix.com> for spotting it.
+ * few mods to make it easier to compile the tests.
+ * added the "Ollie" test to the floating point ones.
+ *
+ * Martin Pool (mbp@samba.org) April 2003
+ *    Remove NO_CONFIG_H so that the test case can be built within a source
+ *    tree with less trouble.
+ *    Remove unnecessary SAFE_FREE() definition.
+ *
+ * Martin Pool (mbp@samba.org) May 2003
+ *    Put in a prototype for dummy_snprintf() to quiet compiler warnings.
+ *
+ *    Move #endif to make sure VA_COPY, LDOUBLE, etc are defined even
+ *    if the C library has some snprintf functions already.
+ *
+ * Darren Tucker (dtucker@zip.com.au) 2005
+ *    Fix bug allowing read overruns of the source string with "%.*s"
+ *    Usually harmless unless the read runs outside the process' allocation
+ *    (eg if your malloc does guard pages) in which case it will segfault.
+ *    From OpenSSH.  Also added test for same.
+ *
+ * Simo Sorce (idra@samba.org) Jan 2006
+ * 
+ *    Add support for position independent parameters 
+ *    fix fmtstr now it conforms to sprintf wrt min.max
