I was getting "Permission denied" error messages when I ran ping, even
as root.
Although ping was still suid, its owner had accidentally been changed
from root to some random user. So even when run by root, it ran with
the privileges of the normal user. I have chowned it back to root and
now everything is back to normal.
Thanks to Andy Walden for putting me on the right track.

Here is the original message:
> Lately ping has stopped working on one of our Digital Unix 4.0

> # ping blizzard
> ping: socket: Permission denied

> The error occurs regardless of which machine is pinged, or which user
> runs ping (normal user or root). Pinging the problematic machine from
> elsewhere works normally, as does ping from our other
> similarly-configured machines. The problem was not fixed by
> rebooting.
