Inadyn is a small and simple DDNS client used in many open source routers and gateways. It automates the task of keeping a DNS record up to date with a user’s dynamic IP address. It is the continuation of the original INADYN by Narcis Ilisei. The goal of this project is to entirely focus on *BSD, UN*X, and various embedded Linux platforms.
ddserver.pl is a simple, small Perl script that acts as a DynDNS-compatible and ZoneEdit-compatible dynamic DNS server. It also provides an HTML Web interface, operating as a CGI script, and has been tested within Apache and lighttpd Web servers. It creates and maintains bind9 named.conf(5) zone files. Simple zone-specific templates and username/password ACLs are supported.
