I installed bastille and ran the configuration program and proceeded to reboot my linode as it explains to do so. I then installed TITAN in an attempt to further lockdown the linode. After my reboot i had restarted my IRCd and been able to connect to IRC using irssi without any difficulties.

I realised that i was unable to connect to rsync.gentoo.org when i tried to 'emerge sync'

I then proceeded to try pinging the domain but had no luck. It seems i can ping IP addresses fine and connect to IP addresses fine but that the DNS is playing up and not resolving hostnames to IP addresses.

I expect i should point out that TITAN made a backup when i used it and i restored the backup successfully with no error messages. I have looked through the bastille configuration script again and dont believe i made any changes that would affect DNS.

Run these commands, and see if that fixes it:

Code:
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -P PREROUTING ACCEPT
iptables -t nat -P POSTROUTING ACCEPT
iptables -t nat -P OUTPUT ACCEPT
iptables -t mangle -P PREROUTING ACCEPT
iptables -t mangle -P OUTPUT ACCEPT
iptables -F
iptables -t nat -F
iptables -t mangle -F
iptables -X
iptables -t nat -X
iptables -t mangle -X

No. What is the output of "cat /etc/resolv.conf"?

cat /etc/nsswitch.conf
passwd: files
shadow: files
group: files
hosts: files dns
networks: files dns
services: db files
protocols: db files
rpc: db files
ethers: db files
netmasks: files
netgroup: files
bootparams: files
automount: files
aliases: files

Somehow this file got fsked up. Ive added dns to the networks line and it works fine :)

Anyway, thanks for your help, much appreciated.
