The default firewall rules on a Red Hat 7.X install do not permit NMB
(i.e. Samba)
You can go and configure this with the GUI, but you need to add something
like this to /etc/sysconfig/ipchains:
-A input -s 0/0 -d 0/0 137:139 -p udp -i eth0 -j ACCEPT
-A input -s 0/0 -d 0/0 137:139 -p tcp -i eth0 -j ACCEPT
I could be slightly off on the exact syntax. This is from memory. It
should, however, provide a starting point.
Good Luck!
Bob.
