You folks are all probably dead on, exactly right, but I recall once, about 18
months ago, that my permissions on one machine went haywire, and it lost the
setuid bit in the permissions.  On some machines, this'd sure enough hurt
things.   Maybe this here (below) could help?

TCSH-april:chuck:~:#103-15:18>ls -l `which ping`

If those good suggestions regarding the firewall turn out not to work, maybe
this could be experimented with?
