File transfer speed issue

Hi all,

I have aproblem with Samba copying (unfortunatly I'm new to samba so my
skills are fairly limited).

I have a sun box (solaris 8) with samba 2.2.2.

Copying from sun to a nt server is fast (as good as you would expect)
however, copying from the nt server to the sun box is slow (files copy
normally, then slow to a complete halt then copy very slowly).

We cannot see anything on a network sniff nor a snoop (packets seem to
just stop transferring).

Has anybody else had this problem or am I the only one?

Any help would be greatly appreciated as I am completly stuck on this
one.

I've attached my smb.conf as I hope this will help.

Thanks in advance,

Colin.

File transfer speed issue

Colin:

    Search the list archives on this issue. I remember this issue being
tracked down to what was called a "rabbit pellet fragmentation"
problem, but I
don't recall the fix. I think there was a M$ patch for win95, etc. that
helped. I have seen this problem as well and posted it a number of times. It
only happens to me intermittently and right now on 2.09 everything is fine.

File transfer speed issue

David,

Thanks for the info but I cannot find anything in my search. I have
searched for rabbit pellet fragmentation and variations.

Any chance you can let me know the url for this problem/soloution?

If not then do you think it's worth me downgrading from 2.2.2 to 2.09?

Thanks for you help,

Colin.

Hi Kohei,

We are running with service pack 6a.

Is there a patch that we need to add?

Regards,

Colin.

Not that I'm aware of.  Umm...  Did you try to transfer files via ftp
etc. to see if it's not the network connection itself?

Yep, ftp is fine so it's not the network or hardware.

File transfer speed issue

Well, comparing your smb.conf to mine, the only differences that I see
pertinent is that I use

keepalive = 30
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=16384 \
SO_RCVBUF=16384 SO_KEEPALIVE

But I honestly think this shouldn't make a performance gain or loss
significant enough to stop data transfer altogether.

The only thing I can say to you at this point is to follow the
DIAGNOSIS.txt that you find in the samba tarball under
"docs/textdocs".
This should help you narrow down where the problem is.  If the problem
is reproducible, then turn on your logging facility and check the log to
see if there is any kind of error messages there.

Sorry I couldn't be of much help.

Kohei,

Thanks for your help so far.

I am going through the DIAGNOSIS.txt but on test 7 it is failiing with
BAD PASSWORD.

Do you know whether the compiled Samba 2.2.2 from Sunfreeware has
shadow password support?

Thanks,

Colin.
