Cannot browse linux SAMBA servers

Hi,

This is a recent problem for me, at one point I had everything working ok.

I have a small local area network. There is one XP server, and three Linux workstations. Each workstation connects to the network through a wireless router. They communicate via subnet 192.168.0.

Each smb.conf file allows this subnet. None is claiming to be master. Each workstation has its own unique workstation name. They are configured with DHCP, so each are assigned a unique address, presumably from the router.

The XP system has the firewall disabled at the moment. I have had it working with the firewall turned on.

I can ping each workstation. To the best of my knowledge, I have no firewall active, but I don't know how to test the ipbtables to see for sure.

I cannot mount any drives on any of the Linux hosts anymore. When I use smbclient -L XP, I can look at my XP server from any other workstation, but cannot go peer-to-peer.

Can someone recommend some debugging steps I might follow to figure out what's going on?

Again, this was working at one point. I've "upgraded" a couple of the linux systems, but the smb.conf files stayed the same, except on the new PC I added.

Something else that seems confusing. If I smbclient into the local workstation, it shows the workgroup correctly, and always shows the local workstation as master. I cannot see any other workstations in the group.

I was following some instructions from a wiki about inspecting a local area network. I haven't solved my problem yet. Here is some more to ponder.

I ran

Code:

nmap -sT 192.168.0.*

and this found all workstations on the lan. I am interested in one, in particular for example. It showed this output:

Interesting ports on 192.168.0.3:
(The 1660 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
139/tcp open netbios-ssn
445/tcp open microsoft-ds
631/tcp open ipp
MAC Address: 00:xx:xx:xx:xx:xx (Netgear)

I further executed

Code:

nmblookup -A 192.168.0.3

and it returned

Looking up status of 192.168.0.3
yadayada <00> - B <ACTIVE>
yadayada <03> - B <ACTIVE>
yadayada <20> - B <ACTIVE>
..__MSBROWSE__. <01> - <GROUP> B <ACTIVE>
yadagroup <00> - <GROUP> B <ACTIVE>
yadagroup <1d> - B <ACTIVE>
yadagroup <1e> - <GROUP> B <ACTIVE>

MAC Address = 00-00-00-00-00-00

I assume this is all good. The yadayada workstation name is correct, as is the yadagroup.

Executing any of the following (all seemed to work at one point)

Code:

smbclient -L \\yadayada
smbclient -L yadayada

it returns a failure, connection to yadayada failed.

Does this give anyone else an idea?
