[CentOS] NIS/YP revelation (I think)

[Scott Ehrlich]

I did discover tcpdump produces an ICMP host <hostname> unreachable error 
during ypbind, but does NOT do so when ypbind is not running.

I also was reminded the firewall on the server is running, but I had these 
exact problems when the firewall was disabled.

Trying to track down the problem via google, and am open to any responses 
people have here...

Thanks.
