Re: [PLUG] Tracking a Dynamic IP address...

If you wanted to go the DIY route, you could always do something like:
curl http://whatismyip.org/ | mail -s "Current IP Address"
root@example.com
Then use procmail on the client machine to pass that IP to a shell script
that will update the hosts file, or dns or whatever
