Hi Jerry,

cmd looks like:
/var/www/localhost/cgi-bin/PingGPSsource.py 192.168.103.75 169.254.0.1

Yes, it is set to be world executable, I chmod-ed it to 777

Well it actually seems as if the script would run but as if php
wouldn't let it execute all the way. I put a print in the first line
and that is what i'm getting back but nothing else...
The python script executes a ping on the remote host and thus takes a
second to execute...
