Log on as 'root'. Run: 'iptables -L -vn'
This will tell you if you have any iptables rules in place.

To find which start-up script starts a firewall on your system:
	cd /etc/rc.d/init.d
	grep iptables *

If the script is called 'firewall' you can turn it off by:
	/etc/rc.d/init.d/firewall stop

Also, be aware that your tcp_wrappers may be part of the problem too. So
check the contents of:
	/etc/hosts.allow
	/etc/hosts.deny

How much documentation on samba could there be before people will just
stop reading ti altogether? It is difficult enough to get folks to read
what is there now. :)

The above might help.
