icmp Operation not permitted message on ping

[don fisher]

Sorry to be back again. My mail and browser work, and I can ping as 
root. When I try to ping as a user I get:

ping: icmp open socket: Operation not permitted

There is probably a group that I need to add to my profile, but it was 
not obvious to me. Suggestions welcome. Is there a way to add groups to 
my account without using system-config-users?

Where are these things documented?

Thanks,
Don
