  • Update deprecated build dependency for dh-systemd

Fixes

  • Issue #174: gnutls.c missing stdint.h, fix for ArchLinux
  • Issue #179: Update easyDNS plugin to new API, by Nicholas Alipaz

v2.2 - 2017-08-09

Changes

  • Use HTTP by default for DYN.com checkip server, used by many DDNS providers that do not have their own. This change is far more user friendly since you no longer have to explicitly set checkip-ssl = false for the most common use-case.
  • Some DDNS providers have multiple IP addresses registered for the same service, as of this release Inadyn immediately tries to connect to the next listed addresses on connection problems.
  • Issue #153: Support for custom HTTP User Agent. Useful with providers that require using a specific brower. Set to, e.g. "Mozilla/4.0", or rely on the default "inadyn/VERSION" user agent.
  • Support for the %% format specifier in custom server URL's, as mentioned in issue #152.
  • Add support for a .conf syntax checker: inadyn --check-config
  • Add support for logging to stderr when running in foreground or without syslog enabled
  • Simplified provider name lookup in .conf file. Now substring match is used, resulting in support for provider Dyn { ... }.
  • Remove libite dependency by importing all its used files into inadyn. This should ease adoption by distributions and end users. All code is under free licenses: BSD, ISC.
  • Import Timur's Debian packaging, adding debconf support

Fixes

  • Issue #152: Do not attempt to create PID file in oneshot mode (-1)
  • Issue #152: Must URL encode custom server URL's
  • Issue #170: Use configured --prefix not hard coded /etc/inadyn.conf
  • Issue #172: Use separate variable for --iface command line option and .conf file option

v2.1 - 2016-12-04

Changes

  • Use HTTPS instead of HTTP by default
  • Support for disabling HTTPS for checkip-server, per provider. Idea from Valery Frolov
  • Add -I,--ident=NAME option for syslog+pidfile name
  • Deprecate --pidfile=NAME option in favor of --ident=NAME

Fixes

  • Issue #150: Custom update URL parser fixes
  • Issue #151: Support for detecting OpenSSL v1.1
  • Issue #144: Clarify use of public vs private IP. It is possible to register private IP addresses in a public DNS
  • Clarify --foreground option in man page
  • Document minimum required versions of libite and libConfuse
  • Portability fixes, replace __progname with a small function, replace %m with %s and strerror(errno).

v2.0 - 2016-09-12

New configuration file format, changed command line options, improved HTTPS support using GnuTLS and Open/LibreSSL. Inadyn now comes with certificate validation enabled by default.

Changes

  • New configuration file format using libConfuse

  • Radically simplified command line, a .conf file is now required

  • Reorganized SSL code, split ssl.c into openssl.c and gnutls.c

  • Strict HTTPS certificate validation is now default. To disable this use strict-ssl = false in the .conf file.

  • Certificate validation uses trusted CA certificates from the system with fall-backs to certain known locations. To override this default handling a ca-trust-file = FILE setting in inadyn.conf can be used to provide the path to another CA cert bundle, in PEM format.

  • Massive overhaul of inadyn(8) and inadyn.conf(5) man pages

  • Support for reading address from interface, including IPv6 addresses

  • Support for calling an external script to get the IP address

  • Support for multiple users @ same provider, idea from Valery Frolov:

      provider [email protected]:1 {
      username    = ian
      password    = secret
      alias       = flemming.no-ip.com
  }

  provider [email protected]:2 {
      username    = james
      password    = bond
      alias       = spectre.no-ip.com
  }

  • Support for ddnss.de and dynv6.com, contributed by Sven Hoefer

  • Support for spdyn.de, on request from Frank Röhm

  • Support for strato.com, contributed by Duncan Overbruck

  • Support for disabling IP address validation: verify-address = false

  • Refactored memory handling and privilige separation to simplify code

  • Refactored logging and backgrounding to simplify code

  • Removed old compatibility symlinks and other required GNU specific files, we now distribute and install README.md and ChangeLog.md

Fixes

  • Fix issue #61: Add HTTPS certificate validation for OpenSSL/LibreSSL
  • Fix issue #67: Use GnuTLS native API for HTTPS
  • Fix DuckDNS: now requires 'www.' prefix in server URL. By Frank Aurich
  • Fix issue #110: Poodle SSL_MODE_SEND_FALLBACK_SCSV not needed

  • Fix issue #102: Relocate cache files /var/run/inadyn to /var/cache/inadyn
  • Fix issue #113: --drop-privs does not work
  • Add actual permissions check to os_check_perms()

  • Fix issue #134: Support wildcard cert with GnuTLS backend

1.99.15 - 2015-09-09

Minor bugfix release.

Changes

  • Support for new API at https://tunnelbroker.net, fixes issue #83. Use [email protected] to use the DYN.com API to update the IPv4 address for your IPv6-in-IPv4 tunnel. Thanks goes to Horst Venzke @hvenzke for reporting this problem!
  • The old API for the IPv6-in-IPv4 system [email protected] is now deprecated. Users should migrate to [email protected]
  • Files generated by the GNU Configure & Build System is now no longer stored in GIT. Instead, users that rely on GIT must run the new ./autogen.sh script to generate the necessary files (configure).

Fixes

  • Fix issue #100: regression from 1.99.13 pidfile is no longer created. Inadyn 1.x semantics incompatible with OpenBSD pidfile() that replaced local version in 1.99.14. Problem found by David Schury @daersc.
  • Fix issue #107: If an IP address update fails, e.g. due to temporary connectivity, HTTP transmission problems, etc. then Inadyn now forces an update in the next IP check cycle. (This is the configurable period interval in inadyn.conf.) Reported by Oliver Graute @redbrain17 and audited by @BulldozerBSG, thanks!
  • Fix issue #108: Update README with correct alias syntax for Namecheap, issue reported by @quazar0

1.99.14 - 2015-07-14

Improved support for configuring custom DDNS providers and support for running in Windows, using Cygwin!

Changes

  • New setting append-myip which, instead of appending your hostname alias, appends the current IP to the server GET update URL. See README or the man pages for more details.
  • Prevent Inadyn from bugging out if it cannot write a cache file when the -o, --once flag is given.
  • Inadyn now defaults to a silent build, use V=1 (like Linux) to get a verbose build. Useful for auto-builders etc.
  • Migrate to libite for functions like pidfile(), strlcpy() etc.
  • Add support for http://GiraDNS.com, thanks to Thorsten Mühlfelder!
  • Add support for https://www.duiadns.net, thanks to Ionut Slaveanu!
  • Add Cygwin support for running Inadyn in Windows, thanks to Scott Mann!

Fixes
