Projects / Dudders


Dudders spells "Dynamically Updating DNS Duly Embracing RSA SIG(0)" (with some poetic license). It points a domain name to a given IP address using the DNS UPDATE protocol and a SIG(0) signature. It is designed with embedded systems in mind and is especially useful as a dynamic DNS solution for a home modem/router with a dynamic IP.

Recent releases

    Release Notes: The update message can be sent over TCP with the -T option.

    •  13 Jul 2008 23:52

      Release Notes: The crypto plugins should no longer export unresolved symbols. The authority can now be overidden with the -m and -z options. This circumvents the search for the master and zone using the local resolver. The manual page is now in section 8, and has been renamed accordingly. The private key parsing is more strict, which prevents some potential segfaults (e.g. when trying to use a dnssec-keygen .key file instead of the .private file).

        Release Notes: Dudders now supports multiple crypto packages at the same time, using dlopen, on supported POSIX platforms. This is enabled by default. Parsing of DNS responses is a little stricter, which prevents some potential segfaults.
