[olug] Expect script help...

[unfie at cox.net]

If you have some web space (free or not), why not upload a text file upon connecting to the 'net that contains your ip, then have your .profile/whatever script download (wget or curl?) that file and export DISPLAY=`cat myip.txt` or something similar?

Although this kills some anominity, it has uses for other problems that might require knowing your IP.
