Hi,
we had upgraded our SAMBA PDC from 3.0.14 to 3.0.22 on a Gentoo system.
Now we have problems with peculiar spwaning of too many "nmbd"
processes.
In smb.conf WINS support is activated, so I would expect two nmb
processes. But as you can see in the process list, during SAMBA is running
after some minutes another nmbd child is spawned. I tracked down the
problem to one example:
We have one primary domain ITCAMPUS, our PDC is BAIKONUR. PIONEER is an
ubuntu host running samba 3.0.22, WINS server disabled. As you can see
from the following snippet of nmbd.log nmbd on BAIKONUR tries to resolve
PIONEER, first per WINS then via DNS lookup and dies.
Afterwards I added PIONEER to our LDAP backend (serves to SAMBA+DNS+DHCP)
and spawning ends. We have several windows hosts in our network, not every
guest host is resolvable via DNS. So every time a foreign WINDOWS host
with its own WORKGROUP is joining our network I expect new nmbd spawning.
We never had such problems with samba 3.0.14, any ideas are appreciated?
thx (Hint: Process list and nmbd.log are taken from different days.)
greetings,
Martin
P.S.
another question: What causes this? (also in bigger nmbd.log snippet
below) BAIKONUR as WINS server don't recognises itself?
