<title>Tell me about Trust Relationships using Samba</title>

<para>
|

Like many, I administer multiple LANs connected together using NT trust
|
||||
relationships. This was implemented about 4 years ago. I now have the
|
||||
occasion to consider performing this same task again, but this time, I
|
||||
would like to implement it solely through samba - no Microsoft PDCs
|
||||
anywhere.

I have read documentation on samba.org regarding NT-style trust

relationships and am now wondering, can I do what I want to? I already
|

have successfully implemented 2 samba servers, but they are not PDCs.
|
||||
They merely act as file servers. I seem to remember, and it appears to
|
||||
be true (according to samba.org) that trust relationships are a
|
||||
challenge.

<title>Samba performance problem due changing kernel (2.4.20 Linux kernel)</title>
|

|

<para>
|
||||
Hi everyone. I am running Gentoo on my server and samba 2.2.8a. Recently
|
||||
I changed kernel version from linux-2.4.19-gentoo-r10 to
|
||||
linux-2.4.20-wolk4.0s. And now I have performance issue with samba. Ok
|
||||
many of you will probably say that move to vanilla sources...well I ried
|
||||
it too and it didn't work. I have 100mb LAN and two computers (linux +
|
||||
Windows2000). Linux server shares directory with DivX files, client
|
||||
(windows2000) plays them via LAN. Before when I was running 2.4.19 kernel
|
||||
everything was fine, but now movies freezes and stops...I tried moving
|
||||
files between server and Windows and it's trerribly slow.
|
||||

|
||||
Grab mii-tool and check the duplex settings on the NIC.
|
||||
My guess is that it is a link layer issue, not an application
|
||||
layer problem. Also run ifconfig and verify that the framing
|
||||
error, collisions, etc... look normal for ethernet.

<title>Corrupt tdb Files</title>

Well today it happend.... our first major troubles using samba. This is
|
||||
no complaints but just some questions :-)
|
||||
Our samba PDC server has been hosting 3 TB of data to our 500+ users
|
||||
[Windows NT/XP] for the last 3 years using samba, no problem.
|
||||
But today all shares went SLOW; very slow. Also the main smbd kept
|
||||
spawning new processes so we had 1600+ running smbd's.... ( while
|
||||
normally we avg. 250 ).
|
||||
It crashed the SUN E3500 cluster twice. After alot of searching I
|
||||
decided to rm ./var/locks/*.tbl and YES I was happy again.
|
||||
|
||||
Q1) Is there any method of keeping the *.tbl files in top condition or
|
||||
how to early detect corruption?
|
||||
|
||||
Q2) What I also would like to mention is that the service latency seems
|
||||
alot lower then before the locks cleanup, any ideas on keeping it top notch?
