dns lookup broken on laptop install
Last modified: 2007-04-18 12:31:46 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.0 i686)
I can ping by IP address but nslookup/dig/host does not resolve names at
Steps to Reproduce:
1. Install beta
2. upgrade to 2.4.2 to get PCMCIA working so I have networking
3. setup /etc/resolv.conf identical to my 7.0 machine or my 6.2 machine
on the same network
4. try using nslookup, dig, or host to resolve names
Actual Results: DNS timeout, no resolution
Expected Results: DNS resolution
Tested at same time on several machines.
Could you check your firewall rules, please ?
Either ipchains -l or iptables -L should give you the rules.
My guess is that you selected high or medium security during installation.
I did select high or medium security. I'll check the rules. After posting and
reporting a bug, I thought that might be the issue. I'll check tonight when I
get back to that laptop! Thanks!
Is the installation manual draft online and does it cover these issues?
Assuming this was caused by the firewall settings because you didn't supply any further information.
