Scenario:
WINS server looses election irregular in a heterogeneous network
Dear Samba-Users,
I have to administer a Samba WINS Server in a heterogenous network. It's a
student hostel with about 200 mixed (Windows, Linux, Mac OS X) computers. We
have a DHCP, which delivers the WINS-Server address to the clients. I don't
have access to the clients.
The problem is, that the WINS-Server (Samba 3.0.27) looses the
Master-Browser election irregulary. I can't configure Samba a way, that
it keeps the MSB.
Example from the log.nmbd:
===
[2008/06/09 22:15:45, 0]
nmbd/nmbd_incomingdgrams.c:process_local_master_announce(309)
process_local_master_announce: Server GUERO at IP 10.0.80.221 is announcing
itself as a local master browser for workgroup WODANLAN and we think we are
master. Forcing election.

Samba name server SHODAN has stopped being a local master browser for
workgroup WODANLAN on subnet 10.0.80.5
*****
===
SHODAN is the name of the server. Today it's GUERO, who is winning the
election. Yesterday, it was another computer.
When I restart the smbd/nmdb it wins the election and the network browsing
operates normally. Is there any way to be sure, that SHODAN keeps the MSB?
At the moment I have a cron, which restarts the smb-server every 30 minutes,
so that it wins the election and becomes the MSB, but that's really a nasty
thing.
This is my configuration:
smb.conf:
===
[global]
workgroup = WODANLAN
netbios name = Shodan
server string = Wodanlan Master Browser
hosts allow = 10.0.80.
log level = 2
domain master = yes
local master = yes
preferred master = yes
enhanced browsing = Yes
os level = 255
wins support = yes
dns proxy = no
===
Can you help me?
Thank you very much

Have you tried setting your "announce version" instead of just
manipulating OS level?
announce version = 4.9 is the default, which is less than XP for example.
Perhaps an "announce version = 5.3" would solve your problem, I dunno.

Dear Charlie,
thank you for the tip of setting "announce version" to keep Master Browser.
But it just keeps Master Browser for 6 hours. This is the nmb-log:

Do you have any other ideas? I don't understand why the election is won when
the server is restarted, but why it is lost, when it keeps a few hours
online.
Best regards,
Timo

Same issue.
I put the following in cron:
#!/bin/sh
PATH=/usr/bin:/usr/sbin:/bin:/sbin
nmblookup -M -- - 2>&1 | grep "IP address of my samba server" >/dev/null 2>&1
if [ $? != 0 ]; then
nmblookup -M -- -|mail -s "Force master browser election" "my email"
/usr/bin/smbcontrol nmbd force-election
fi
The smbcontrol command has the same effect as restarting samba
(election is won).
Then I tell the person using the PC I see in the email to turn off the
"browser" service in his/her XP to avoid the same issue in the future.

Dear Giulio,
thank you for the script. I will use it to "solve" my problem. I
searched for a command, which restarts an election.
Although it's not really a good solution, it is much better than my
cron-samba-restart.
Best regards,
Timo
