[Wylug-help] Can't ping NIC

[Nik Jewell]

Peter

If you run the following command:

cat /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts

and it comes back as "1" rather than "0" then your box is configured to
ignore ping requests (this sort of thing is usually set up with a line
in /etc/sysclt.conf).

I don't if this is the cause or not, but it's worth checking.
