I'm using Samba and windbindd on my linux boxes. Without a firewall up on the linux box I have no trouble resolving LAN machine names:
user@laptop-linux:~$ ping desktop
PING desktop (192.168.1.100) 56(84) bytes of data.
64 bytes from 192.168.1.100: icmp_seq=1 ttl=128 time=0.878 ms
when I start the firewall I get:
user@laptop-linux:~$ ping desktop
ping: unknown host desktop
I have opened up the Samba ports (137-139 445) as well as the mDNS port 5353 with no effect. WINS has been enabled in nsswitch.conf and I've also tried removing the mdns4 entries for host lookup. I can see the DNS query going out regular DNS with my ISP domain suffix attached which is not what I want. I want to use wins / NetBIOS to do the work. Do I have allow some form of broadcast port? Can this be done while maintaining security? I want to have a firewall running on my laptop because I access open hotspots on a regular basis. Thanks
