RE: [Samba] Slow file transfers from server to XP clients

2006-06-04 Thread Scott R. Burns
I had a similar problem in the past and the problem was I locked the NIC and
I think the switch (HP Procurve 4000M I think) at 100Mb/full. Seemed like a
good idea at the time. Changing the ifconfig to auto-config and the hub as
well resolved the issue.

This is a known documented issue with the link negotiation architecture from
what I remember. There was a HP whitepaper on it.

Subject: [Samba] Slow file transfers from server to XP clients

Hey everyone, I'm sure this topic has been discussed, but I've looked
through history and done google searches and just haven't found a resolution
yet so I'm hoping the experts can help me.

Running Fedora Core 5 and Samba ???  Not sure the version off-hand.
Clients are XP Professional

The problem is miserably slow file transfers from the server to the XP
clients (and it's primary purpose is a file server) and I mean along the
lines of 4.5 to 5 hours for a 5 gig directory.  This is over a 100mb
switched network with a really good HP managed switch.

Transferring the same directory from client to client takes less than 45
minutes.

Transferring data to a Win 98 client on the other hand moves much faster,
not as fast as win to win but acceptably fast.

I have had the same exact problem through about six generations of
Linux/samba from RedHat 9 and each version of Fedora.  Each time I have done
a complete format/re-install and same problem.

I have also tried switching the Nic in the server with a working pull from a
client and no change.  I even forced the Nic to 100 full in dos before
placing in the Linux box.

Really at an end of my knowledge which was limited in the first place, just
not sure why this isn't working and really trying to avoid putting 2k3 on
there.  Any Help would be greatly appreciated, or if the topic has been
discussed ad-nauseam then if you could post some links or point me in the
right direction that would be helpful.

[Samba] Problem with MS Visual SourceSafe and samba V3.0.14anb1

2005-10-13 Thread Scott R. Burns
I have upgraded my samba on a NetBSD/i386 V2.0.2. I was previously at
V3.0.10nb2 and I am now at: V3.0.14anb1. My developers are starting to
report problems when checking source code in and out of VisualSource Safe.
Most users are W2K SP4 or WXP SP1a or SP2. Problem has been reported by both
XP and W2K users.

The problems reported in the samba log file are thousands of:

[2005/10/11 16:07:05, 0] lib/util.c:Realloc(971)
  Memory allocation error: failed to expand to 4896 bytes
[2005/10/11 16:07:05, 0] lib/util.c:Realloc(971)
  Memory allocation error: failed to expand to 4896 bytes
[2005/10/11 16:07:05, 0] lib/util.c:Realloc(971)
  Memory allocation error: failed to expand to 4896 bytes


The 4896 value is quite common, but it does vary to other values in the 4K
range.

I have observed a couple of other reports about Realloc() failing on the net
but nothing specific. Does anyone know if a specific release fixes this
before I attempt to revert backwards ?

Thanks

Scott...
