Nameserver update for inwx (nsupdate)

Update nameserver entrys at inwx with the current WAN IP (DynDNS)

nsbackup is a shell script that uses curl and the inwx API to update nameserver entrys at inwx with the current WAN IP. It supports IPv4 and IPv6.

Place your config files in the nsupdate.d folder.

Requirements

In order to run you need to have curl and awk installed, as well as drill or nslookup.

At least one config file needs to exist ending with .config. A "sample.config.dist" is provided.
