Samba problems (major!)

FirebarUK · 13 Apr 2006 at 23:43

Hi,

Just set up my Samba file server. Its a little PIII 866, 256MB Ram etc etc. Its running CentOS 4.3.

Configured it for 2 users on my home network, works a treat. Limiting ip's from 192.168.0. n all that.

The 2 clients are both Windows machines. I've only got access to 1 at the moment, but whenever I try to write a file onto the samba share, the transfer rate chugs along and it starts copying, then about 2 seconds later progress stops. Monitoring using scp (via ssh utils) shows the transfer rate just peetering out slow. Eventually, whatever app it is, crashes be it iTunes or Explorer.exe. Thing is, read performance is fabulous and there are no problems there. Anyone have any ideas why its doing this?

Thanks.

Would be helpful if you posted up your samba logs

Yes that would help wouldn't it

Code:

There we go

Seems to just connect then disconnect. Looking at the top part of this snippet it shows something like this;

Code:

[2006/04/13 23:28:13, 0] lib/util_sock.c:send_smb(647)
  Error writing 5 bytes to client. -1. (Connection reset by peer)

So XP isn't letting the Linux box chat back to it perhaps? Don't know how to rectify this..

Just checked from my Laptop running Gentoo. Can access and write stuff to the share no problems.

FirebarUK · 14 Apr 2006 at 08:47

Ok another worrying thing

I copied over a CD iso from my windows machine and as usual it crashed shortly after transfer started. I left it there for a while, 10 mins or so seeing if it would recover. I've just checked the shared folder and the CD ISO is there, downloaded it onto my Gentoo laptop and ran a checksum - its all there!

I'm mighty confused now :S

thats "normal" on win2k or above you could close port 445 and should see these errors go.

Which version of linux is samba running on? quite an old version of samba.

will see what else i can find out.

Thank for your help.

Yeah I've looked into closing that port, as you said those errors are normal. Lazy Windows connection management stuff I guess.

I'm using CentOS 4.3, I've also tried Ubuntu 5.10 grabbing samba from the standard repos.

FirebarUK · 17 Apr 2006 at 10:11

Well I've just installed Windows 2000 pro and that does the same thing. It must be some form of hardware issue.

Hi

have a look see whats in /var/log/messages also have you tried over at the centos forums?

cheers

Hey,

Yeah I've asked, but no reply.

Just on my W2k machine I seem to have it working. Seem being the word there...

I just added the name and IP of the machine to the hosts file on my XP box.... dun dun duuuun.
