I have a Linux box sitting behind a Linksys router. I want to create a script that will find the external WAN address the router is presenting, and update a remote file if that information has changed. Most of it is relatively simple, but I was wondering if there is a script already out there, or easily creatable that does this? There are Windows apps like IPPoster (http://www.omconsults.com/ipposter.htm) that do this, but I'm looking for one on Linux. Thanks, Chris Evans chris at fuseware.com http://www.fuseware.com
