+SOCKET_WRAPPER
+==============
+
+This is a modification of initial socket_wrapper (https://cwrap.org/socket_wrapper.html) library.
+Essence : functionally both libraries are equal. But here implemented some minor changes intended
+to ensure the possibility of using arbitrary IP addresses instead of private-range IP addresses.
+
+DESCRIPTION
+-----------
+
+More details can be found in the manpage:
+
+ man -l ./doc/socket_wrapper.1
+
+or the raw text version:
+
+ less ./doc/socket_wrapper.1.txt
+
+For installation instructions please take a look at the README.install file.

+Obtaining the sources
+=====================
+
+Source tarballs for socket_wrapper can be downloaded from
+
+ https://ftp.samba.org/pub/cwrap/
+
+The source code repository for socket wrapper is located under
+
+ git://git.samba.org/socket_wrapper.git
+
+To create a local copy, run
+
+ $ git clone git://git.samba.org/socket_wrapper.git
+ $ cd socket_wrapper
+
+Building from sources
+=====================
+
+socket_wrapper uses cmake (www.cmake.org) as its build system.
+
+In an unpacked sources base directory, create a directory to
+contain the build results, e.g.
+
+ $ mkdir obj
+ $ cd obj
+
+Note that "obj" is just an example. The directory can
+be named arbitrarily.
+
+Next, run cmake to configure the build, e.g.
+
+ $ cmake -DCMAKE_INSTALL_PREFIX=<prefix> ..
+
+or on a 64 bit red hat system:
+
+ $ cmake -DCMAKE_INSTALL_PREFIX=<prefix> -DLIB_SUFFIX=64 ..
+
+The "<prefix>" should be replaced by the intended installation
+target prefix directory, typically /usr or /usr/local.
+
+Note that the target directory does not have to be a direct
+or indirect subdirectory of the source base directory: It can
+be an arbitrary directory in the system. In the general case,
+".." has to be replaced by a relative or absolute path of the
+source base directory in the "cmake" command line.
+
+One can control the build type with "-DCMAKE_BUILD_TYPE=<mode>"
+where <mode> can be one of Debug, Release, RelWithDebInfo, and
+some more (see cmake.org). The default is "RelWithDebInfo".
+
+After configuring with cmake, run the build with
+
+ $ make
+
+Unit testing
+============
+
+In order to support running the test suite after building,
+the cmocka unit test framework needs to be installed (cmocka.org),
+and you need to specify
+
+ -DUNIT_TESTING=ON
+
+in the cmake run. After running "make",
+
+ $ make test
+
+runs the test suite.
+
+Installing
+==========
+
+socket_wrapper is installed into the prefix directory
+after running "cmake" and "make" with
+
+ $ make install
+

+TODO
+=====
+
+This is the TODO list of this project. It should give you some hints of things
+which need to be implemented. If you can spend some time on this project, then
+look at the list below.
+
+
+Library:
+---------
+
+Goals:
+* Thread safety
+* The proposed way ==> - fd-passing for tcp sockets (for free)
+ Approach:
+ - tdb "in small". So a "db file".
+ - for each socket an entry in the db file
+ (file, mmap, robust mutex. e.g. one file per local ip addr)
+ - socket_info : structure in db. protected by pthread robust mutexes
+ - socket_info_fd : --> pointer into mmap area of db
+ - free-list
+ - fd-passing: pass index in array
+ - the last element we pass is not a fd but the index number in the
+ mmaped file
+* Use realpath() in socket_wrapper_dir().
+
+Testing:
+---------
+* Add a test to make sure detect stale file descriptors.
+* Add a test for sento() to broadcast 255.255.255.255.
+* Add a test to check that read/readv/send/ only work on connected sockets.
+* Add unit tests for conversion functions like convert_in_un_remote().
+* Add threaded tests.

+=================
+:revdate: 2015-08-11
+
+NAME
+----
+
+socket_wrapper - A library passing all socket communications through unix sockets.
+
+SYNOPSIS
+--------
+
+LD_PRELOAD=libsocket_wrapper.so SOCKET_WRAPPER_DIR=/tmp/tmp.bQRELqDrhM SOCKET_WRAPPER_DEFAULT_IFACE=10 *./myapplication*
+
+DESCRIPTION
+-----------
+
+socket_wrapper aims to help client/server software development teams willing to
+gain full functional test coverage. It makes possible to run several instances
+of the full software stack on the same machine and perform locally functional
+testing of complex network configurations.
+
+- Redirects all network communication to happen over unix sockets.
+- Support for IPv4 and IPv6 socket and addressing emulation.
+- Ablility to capture network traffic in pcap format.
+
+ENVIRONMENT VARIABLES
+---------------------
+
+*SOCKET_WRAPPER_DIR*::
+
+The user defines a directory where to put all the unix sockets using the
+envionment variable "SOCKET_WRAPPER_DIR=/path/to/socket_dir". When a server
+opens a port or a client wants to connect, socket_wrapper will translate IP
+addresses to a special socket_wrapper name and look for the relevant unix
+socket in the SOCKET_WRAPPER_DIR.
+
+*SOCKET_WRAPPER_DEFAULT_IFACE*::
+
+Additionally, the default interface to be used by an application is defined
+with "SOCKET_WRAPPER_DEFAULT_IFACE=<ID>" where <ID> is between 2 and 254. This
+is analogous to use the IPv4 addresses "127.0.0.<ID>" or IPv6 addresses
+"fd00::5357:5f<IDx>" (where <IDx> is a hexadecimal presentation of <ID>). You
+should always set the default interface. If you listen on INADDR_ANY then it
+will use the default interface to listen on.
+
+*SOCKET_WRAPPER_PCAP_FILE*::
+
+When debugging, it is often interesting to investigate the network traffic
+between the client and server within your application. If you define
+SOCKET_WRAPPER_PCAP_FILE=/path/to/file.pcap, socket_wrapper will dump all your
+network traffic to the specified file. After the test has been finished you're
+able to open the file for example with Wireshark.
+
+*SOCKET_WRAPPER_MTU*::
+
+With this variable you can change the MTU size. However we do not recomment to
+do that as the default size of 1500 byte is best for formatting PCAP files.
+
+The minimum value you can set is 512 and the maximum 32768.
+
+*SOCKET_WRAPPER_DEBUGLEVEL*::
+
+If you need to see what is going on in socket_wrapper itself or try to find a
+bug, you can enable logging support in socket_wrapper if you built it with
+debug symbols.
+
+- 0 = ERROR
+- 1 = WARNING

+
+EXAMPLE
+-------
+
+ # Open a console and create a directory for the unix sockets.
+ $ mktemp -d
+ /tmp/tmp.bQRELqDrhM
+
+ # Then start nc to listen for network traffic using the temporary directory.
+ $ LD_PRELOAD=libsocket_wrapper.so \
+ SOCKET_WRAPPER_DIR=/tmp/tmp.bQRELqDrhM \
+ SOCKET_WRAPPER_DEFAULT_IFACE=10 nc -v -l 127.0.0.10 7
+
+ # (If nc, listens on 0.0.0.0 then listener will be open on 127.0.0.10 because
+ # it is the default interface)
+
+ # Now open another console and start 'nc' as a client to connect to the server:
+ $ LD_PRELOAD=libsocket_wrapper.so \
+ SOCKET_WRAPPER_DIR=/tmp/tmp.bQRELqDrhM \
+ SOCKET_WRAPPER_DEFAULT_IFACE=100 nc -v 127.0.0.10 7
+
+ # (The client will use the address 127.0.0.100 when connecting to the server)
+ # Now you can type 'Hello!' which will be sent to the server and should appear
+ # in the console output of the server.
