I have a user w/ puzzling error. We have not been able to get a tcpdump or

this. I did find some older posts that point to possible
client issues.
We're running samba 3.0.25b on RHEL4.
The user reports:
I am getting an error whenever I want to make a copy of a MS Excel file on
my shared network drive:
(From windows explorer) I was trying to create a copy, and when I do the
paste I get the error.
Cannot copy _filename_: The specified network name is no longer
available."
And then the file that is created is corrupt. The original file is about
240K.
Now for the timing part. If she executes the copy command, and waits
(count 1,2,3,4 seconds) then it seems like it works.
Seems to be a common problem that no one has been able to address yet. When
it does it to me, it creates a zero-length file. Repeating the operation at
any time up to about 2-3 minutes delay causes winders to ask if I want to
overwrite the file. If I say Yes, I get a good copy.
I see it mostly when copying video files to a Samba share.
One possible explanation is that WinXP tries both the low port (139 ?) and
the high port (445 ?) at about the same time, and continues the transaction
with which ever port answers first, leaving the other one to die. Some sort
of collision results. I added a line to smb.conf:
smb ports = 139
This is supposed to help if you see this in the logs:
get peername failed; endpoint not connected
Using port 445 or 443 (I forget which) is supposed to be better but
Win95/98/ME clients don't support that, and I don't know if Win2k does, but
I suspect it does.
The bad news: I still get the "Network name not available" error from time
to time. But it's better.
I just make very sure not to do any file moves, I copy and delete.
Sometimes I have to perform a copy or save a second time and overwrite the
zero-length file. But that gets me where I'm going.
