right! but I in fact do execute a ping after creating an ssh handle
but i don't believe the problem is there.
I included some debug prints into my script that get tthrough to php
until we're at a certain position, which is weird...
it's like this:

***script start***
[a few global variable definitions]
print "PingGPSsource.py - start"
[reading command line arguments]
print "PingGPSsource.py - Got arguments"
print "prgIP:"+prgIP
print "avlIP:"+avlIP
print "prgPass:"+prgPass
print "this is before the writelog() implementation"
[writelog() function implementation which is fairly small]
print "and this is after"

print "start script" - this is not printing anymore and the script
appears to be terminated!
That's weird. isn't it?
Any clues there? :o
Thanbks a lot! And I'm sorry if ppl tell want to redirect me to a
python group, i'm aware f the fact that this maybe a python issue but
the script seems to work well when executed from the shell directly...
