Unable to access Samba share on CentOS 5.4 from windows XP or Vista
 

I can't be the first one with this problem. What am I missing?

I have setup Samba servers in the past, just none under SELinux. The last one I configured was a couple years ago, so I wouldn't doubt I'm a bit rusty.


---- Environment summary:
Clean server install of CentOS 5.4 includes SELinux
- lets call this 'server'
- updated samba to 3.0.33-3.15.el5_4.1

Client1 - Windows XP sp4 - WINS configuration uses 'server' noted above
Client2 - Windows Vista - WINS configuration uses 'server' noted above

---- What works / what doesn't ------
Clients can see the server (XP and vista) in network neighborhood.
The following does not work from windows (xp or vista)
net view
net view \\server
net view \\server-ip
net view \\server\share

This does work on the server
smbclient -L \\server
smbclient -L \\server --user validuser
smbclient -L \\client1 --user validuser


---- What I have configured and tried (config/output below) --------
firewall ports for samba are open
SELinux enforcing or permissive
file context is set on share
samba booleans are set

***firewall
-A RH-Firewall-1-INPUT -s 192.168.0.0/24 -m state --state NEW -m tcp -p tcp --dport 445 -j ACCEPT

You don't mention what version of XP and Vista. Are they the home version?
If so, that is most likely the problem.

Sorry forgot that part.
XP is Pro SP4
Vista is Home.

Also as a new note.... I disabled the firewall and can get through now. What rules do I need then to get Samba working? I vaguely remember doing this about 11 years ago. Now if I can only dust off the system which is sitting in my basement with the server running samba, Apache and a router..... Now if I can only remember the root password....

Somewhat on topic. I have noticed errors in the XP pro systems log indicating an error when the CentOS server attempts to become the browse master for the workgroup.

--- names changed to protect the innocent ----
The master browser has received a server announcement from the computer SERVER that believes that it is the master browser for the domain on transport NetBT_Tcpip_{AAAABBBB-EEEE-EEEE-. The master browser is stopping or an election is being forced.

Here is an update...
I disabled the firewall and everything started to work. It turns out I added the firewall rules in iptables after the -DENY rule. Once I moved the Samba rules before the DENY rule, everything worked fine. Silly mistake on my part. I know better than that. Thanks for the help.
