Code: [root@Omega ~]# host www.google.com *** www.google.com does not exist (Authoritative answer) for some reason it is dns querying: PTR 255.255.255.255.in-addr.arpa and predictably my dns server replies with not found, any ideas?

Code:

# Generated by dhcpcd for interface eth0
search hsd1.ca.comcast.net.
nameserver 68.87.76.178
nameserver 68.87.78.130

seems normal.. those are my isp's nameservers.

while were at it heres /etc/hosts

Code:

#
# /etc/hosts: static lookup table for host names
#

#<ip-address>   <hostname.domain.org>   <hostname>
127.0.0.1       localhost
127.0.0.1       Omega.schreknet.net     Omega

# End of file

Code: 127.0.0.1 Omega.schreknet.net Omega You want that to apply to your external interface, right? e.g.: Code: 10.0.0.80 Omega.schreknet.net Omega I'm not sure if that may be related to the problem.
