[SOLVED] Resolving HOSTNAME with ufw firewall

fettouhi · 2012-02-18 16:18:29

I've been having this issue with my firewall for ages now since I switched away from firestarter to now ufw. My problem with the firewall is that I can't get it to resolve the HOSTNAME of my server and windows machines when it is turned on. I can only get to them via their ip addresses. But hen I turn off my firewall then I can resolve the hostname and view them in Dolphin for example under network --> samba shares. I came across this post on the ubuntu forums

http://ubuntuforums.org/showthread.php?p=11501082

but that doesn't seem to work for me either. Can anyone tell how to set up a firewall (doesn't have to be ufw) with support for hostname resolving?

I don't have any experience with ufw, but you could just use iptables and explicitly allow netbios traffic.

Try this:

sudo ufw allow 53
sudo ufw allow 137
sudo ufw allow 138
sudo ufw allow 139

Yes that helped, now I can browse my other machines via Dolphin without turning of the firewall. I had already 137, 138 and 139 loaded but not 53. Many thanks for all the suggestions!

Just for clarification's sake, ufw is a frontend for iptables.

ufw allow from 192.168.1.0/24 to any app CIFS

works fine for me

Edit/ nm already had a rule for my dns on 53, but I use appnames as found in /etc/ufw/applications.d, so for DNS it would simply be

ufw allow from 192.168.1.0/24 to any app DNS
