greetings,

if all you really want is to implement 'ping' with python, this page:
http://the-tech.mit.edu/~jeremy/python/

has an implementation which I have used and I know works if run as root. in
fact, since it's kind of old (pre-1.5), it would be a good excercise to
reimplement using the 'struct' module (as the page suggests).

hope that helps...

regards,
J
