Enhanced DUC is a dynamic DNS update client and daemon. Primarily it's written for use with the DNS services that NoIP provide. However: the protocol "is in an open format used by other service providers". I began working on the project in November 2015. The goal is to create a better update client for UNIX by using modern C coding practices.
To clone the repository use Git.
$ git clone https://github.com/uhlin/enhanced-duc.git
Enhanced DUC depends on the OpenSSL
toolkit. Which means that on, for example, a Debian GNU/Linux system
you need to install a package with name
libssl-dev before building:
# apt install libssl-dev
Building and installing
$ cd /path/to/source
If your system comes with
strlcat() please edit
$ make $ sudo make install
-h Print help -c Create a config file by asking the user for input. The user will be given the opportunity to choose a location for the config file, i.e. where to create it. -x <path> Start the DUC with the config file specified by path -D Turn on debug mode -o Don't cycle, i.e. don't periodically check for IP changes. Only update the hostname(s) once. -B Run in the background and act as a daemon
Good to know
- If the program isn't running as a daemon it can be terminated with CTRL+C.
- If port 443 is specified TLS/SSL will be enabled.
- Valid ports are 80, 443 and 8245.
- Building for GNU/Linux was broken in v1.2 - v1.3.1.
- Please read the system log, possibly
/var/log/daemon(depending on your UNIX variant).
