Additionally to a global TSIG to be used for all record updates, separate TSIGs can individually be specified per record, per zone, and per nameserver. + +Proper removal of TXT records +----------------------------- + +dehydrated-nsupdate removes records after succesfull verification. + +bind9-dnsutils and knot-dnsutils support +---------------------------------------- + +dehydrated-nsupdate works with both nsupdate (bind9) and knsupdate (knot). + +IDN handling +------------ + +dehydrated-nsupdate works with IDN domains by not expanding the punycode to update the correct records. + +Usage +===== + +dehydrated-hook(1) is a prerequisite for dehydrated-nsupdate. + +Installation +------------ + +| sudo echo CHALLENGETYPE="dns-01" > /etc/dehydrated/conf.d/zz-challengetype.sh +| sudo ln -s /usr/bin/dehydrated-nsupdate /etc/dehydrated/hook.d/deploy_challenge.nsupdate +| sudo ln -s /usr/bin/dehydrated-nsupdate /etc/dehydrated/hook.d/clean_challenge.nsupdate + +Removal +------- + +| sudo rm -f /etc/dehydrated/conf.d/zz-challengetype.sh +| sudo rm -f /etc/dehydrated/hook.d/deploy_challenge.nsupdate +| sudo rm -f /etc/dehydrated/hook.d/clean_challenge.nsupdate + +Configuration +============= + +Depending on the nameserver requirements, dehydrated-nsupdate can send record updates either unauthenticated or using a TSIG (recommended). + +A TSIG file consists of one single line containing the key (nsupdate/knsupdate do not allow comments), e.g.: + +| +| hmac-sha512:example:/LXPy6U8HAWA+QmvulZWm0owsQgNf8qJ5MNLTvirzvVtDb+PzLKoBmVHjnL6TUffkvRYa7Do448dSIrAuJ1G/A== + +Instead of using a global TSIG for all record update, specific TSIGs can be used individually per record, zone, and nameserver. + +The lookup hierarchy is the following (first match wins): + +| +| /etc/dehydrated/tsig/${record}.key +| /etc/dehydrated/tsig/${zone}.key +| /etc/dehydrated/tsig/${nameserver}.key +| /etc/dehydrated/tsig.key +| +| TSIG_KEYFILE variable in /etc/default/dehydrated-nsupdate/* +| TSIG_KEYFILE variable in /etc/default/dehydrated-nsupdate + +In order to explicitly not use a TSIG for a specific record, zone, or nameserver, an empty keyfile or a keyfile with only comments can be used, e.g.: + +| +| echo "# disabled" > /etc/dehydrated/tsig/ns1.example.org.key + +Files +===== + +The following files are used: + +/etc/dehydrated/tsig.key: + default location for global TSIG key to be used. + +/etc/dehydrated/tsig/${record}.key, /etc/dehydrated/tsig/${zone}.key, /etc/dehydrated/tsig/${nameserver}.key: + default locations for specific TSIG keys to be used individually per record, zone, or nameserver. + +/etc/default/dehydrated-nsupdate, /etc/default/dehydrated-nsupdate.d/\*: + configuration file, currently only used for TSIG_KEYFILE variable pointing to the location of the global TSIG key to be used (default: /etc/dehydrated/tsig.key). + +See also +======== + +| dehydrated(1), +| dehydrated-cron(1), +| dehydrated-hook(1). + +Homepage +======== + +More information about service-tools and the Open Infrastructure project can be found on the homepage (https://open-infrastructure.net). + +Contact +======= + +Bug reports, feature requests, help, patches, support and everything else are welcome on the Open Infrastructure Software Mailing List <software@lists.open-infrastructure.net>. + +Debian specific bugs can also be reported in the Debian Bug Tracking System (https://bugs.debian.org). + +Authors +======= + +service-tools were written by Daniel Baumann <daniel.baumann@open-infrastructure.net> and others. diff --git a/dehydrated/share/man/man.in b/dehydrated/share/man/man.in new file mode 100644 index 0000000..bcc6362 --- /dev/null +++ b/dehydrated/share/man/man.in @@ -0,0 +1,19 @@ +.\" Open Infrastructure: service-tools +.\" +.\" Copyright (C) 2014-2023 Daniel Baumann <daniel.baumann@open-infrastructure.net> +.\" +.\" SPDX-License-Identifier: GPL-3.0+ +.\" +.\" This program is free software: you can redistribute it and/or modify +.\" it under the terms of the GNU General Public License as published by +.\" the Free Software Foundation, either version 3 of the License, or +.\" (at your option) any later version. +.\" +.\" This program is distributed in the hope that it will be useful, +.\" but WITHOUT ANY WARRANTY; without even the implied warranty of +.\" MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
