Default ping problem

fc16 with latest updates.

Pinging my gateway:
$ ping 192.168.42.129
ping: icmp open socket: Operation not permitted

Now as root:

# ping 192.168.42.129
PING 192.168.42.129 (192.168.42.129) 56(84) bytes of data.
64 bytes from 192.168.42.129: icmp_req=1 ttl=64 time=3.53 ms
64 bytes from 192.168.42.129: icmp_req=2 ttl=64 time=2.65 ms
64 bytes from 192.168.42.129: icmp_req=3 ttl=64 time=2.83 ms

When was this change put in place?

It hasn't...... I say this since everything works just fine for me on my fully
updated f16 system.

Assuming you have the default LS_COLORS defined when you do "ls /bin/ping" you should
see it listed in black on a red background.

If not, something has *been* changed.

Now /bin/mount is in white on a red background which indicates the suid bit is set.
I forget what black on a red background means.

I suppose the easiest way to fix the issue would be to....

yum reinstall iputils

This sounds like you have iptables blocking icmp. Check your firewall rules.
