Hi list,
once again looking for some good advice. I apologize for the long email and for
the mistakes I could have done.
I'm running Samba 3.0.2-6.3E on White box linux 3.0 kernel 2.4.21-4.EL
(clone of Red Hat EL 3.0), the environment is a Win 2k ADS domain. Users log
into the shares (just common folders - no home dir) using winbind. Everything
works fine for days, but a couple time the server froze and I was unable to even
log in from console. Last time it happened, I could have a look at processes
running on the box cause I had an already opened shell, and I found winbindd was
using 149M memory. I couldn't ping from or to the box (1 ping success on 6
circa) and restarting winbindd and network solved the problem. Now everything is
working fine, the server has not been restarted.
I had a look at the logs, and this is what I think is more important:
log.smbd
a lot of:
[2004/05/05 14:54:54, 0] lib/util_sock.c:get_peer_addr(952)
getpeername failed. Error was Transport endpoint is not connected
I read that this means a broken connection, but then how can it be that just
restarting network services all goes back working fine? Couldn't it be that
in any way samba interacting with network produced a network collapse?

Is it ok that SID for domain is FBCMEDIA.COM S-0-0 ?? If I do net getlocalsid
fbcmedia I get S-1-5-21-735.....and so on.
All net commands and groupmappings are working, wbinfo ok.

What does it mean connection denied from 0.0.0.0? I have logs 0.0.0.0.log in the
log dir, what does it mean?
I have been looking in the mailing list and googling in the last two days, but I
couldn't find a final answer. It looks like it can be related to network
problems (but restarting service network wouldn't fix it I think) or
iptables, but it looks and manifest like a random issue. It has been working
fine for many days, and nothing has been changed lately.
If you're still there, thanks for reading. Any idea is really welcome, and
much more welcome if possible, would be a hint on how to monitor the linux box
(for ex how can I understand what froze the network?) , which tools to use (I
can figure out myself how to use them, not asking for a tutorial), so that I can
be much more useful to the list than just ask for help ;-)
Thanks for you time
Simone
