This is a program which will compare the address of an interface with the address of a remote host and send an http request if they differ. It is especially good for updating your dynamic dns with services like afraid.org, who offer a direct url for updating.
Usage: ./rgddnsupdate ifN myhost.com remotehost.com port url
Hope you like it, Matt
