Unable to find the Domain Master Browser error in samba

vrillusions · 08-21-2005, 03:40 AM

As many threads I've seen about this, couldn't find an answer, maybe I'm just missing something.

I have a firewall that has a few different subnets (a wireless, lan, and dmz) and I want all of them to be able to see computers on each other's networks to browse network shares (I'm working on a seperate file server for the dmz for security, but I only have so much money

). Right now I have the firewall set as the wins server, all computers are set to use it for the wins server. After a very long time, the network browser in windows won't show any computer, but I can connect to them using //machine/ (which doesn't work without the wins server), it will then show up in the list of computers on the network once I try to connect to it.

This is the error that's coming up in the error logs:

Code:

Aug 21 02:56:33 localhost nmbd[12883]:   Unable to sync browse lists in this workgroup.

(it shows up three times whenever I try to run it)

my smb.conf file is as follows:

Code:

[global]
        dns proxy = no 
        load printers = no 
        server string = WINS server
        socket options = TCP_NODELAY
        workgroup = VRILLUSIONS
        netbios name = alev
        os level = 75
        prefered master = yes
        local master = yes
        domain master = no
        interfaces = eth2 eth3 eth4
        security = user
        keepalive = 60
        max log size = 50
        wins support = true

eth2, eth3, and eth4 are the interfaces that the local subnets are on. eth0, which I leave out of there for security, is the internet.

I have tried both yes and no for domain master as well as prefered master and the results are always the same. I made sure all other linux server have the os level lower and the prefered master and domain master = no.

Also, there is no PDC or domain controller set anywhere.

Running nmblookup -U 127.0.0.1 -R '*' from the firewall:

Code:

querying * on 127.0.0.1
D.D.D.1 *<00>
L.L.L.1 *<00>
W.W.W.1 *<00>

where D.D.D.1 is the ip of the dmz interface, L.L.L.1 is the ip of the LAN interface, and W.W.W.1 is the ip of the wireless interface.

Running nmblookup -U 127.0.0.1 -R 'sofiya' (a server on the dmz) from the firewall

Code:

querying sofiya on 127.0.0.1
D.D.D.20 sofiya<00>

So it appears that lookups are working fine, it's just not able to list all of them in network neighborhood, and I keep getting that error in the logs. It appears to be mostly harmless, but I still don't want to keep getting those errors messages to me from logcheck, and if it wasn't in one of the default samba rules to ignore, it must be a important one. Thanks for any help on this.

(edit)
btw, this is on Debian 3.1 if that is any help

The error messages refer to the fact that there is NO PDC in the network, which is quite correct..

Change the firewall os level to 20
Don't let it become the Preferred Master Browser, just a wins server..

In each other linux server, at least one per subnet, make sure they use the firewall wins server..
Make their os level 99, make them Preferred Master Browser add the wins server line to smb.conf
wins server = firewall subnet ip number
Obviously each subnet will use a different ip number..
change each /etc/nsswitch to include wins as an option

This way each subnet is in charge of it's browse list, and uses the firewall for wins..
Make sure everyone who uses cross-subnet browsing uses the wins server.

This is a good chance to use dhcp to it's best to make sure everyone gets all the necessary settings..
