I chased this elusive problem for a year. I'm still running 3.09-2.3 but I
see it on other versions.
Tell me, do you get this problem when you drag/n/drop a file into a folder
on the samba share? And can you prevent this problem from occurring by the
Click in the target window on the samba machine (this is on the XP
desktop). Press F5 to refresh the view. Wait about a second. Immediately
start your copy. When I do this, the errors, previously reported to the
desktop and to my server log, don't occur.
I've been told that it's a WinXP only issue, that it attempts to connect on
ports 445 and 139 nearly simultaneously, and then proceeds to talk over
whichever one answers first. I'm told that Win2k clients won't have this
problem, and Win98 clients don't use port 445 so it doesn't arise there.
Anyone have evidence to the contrary (so far)?
My thinking is that WinXP improperly responds to an attempt to open a
conversation on a different port than the one Samba expects. Maybe the TCP
stack on SuSE is more rigorous and respects the sequence numbers and
considers a connection... ...a connection. Dunno. Need to get busy with
First thing I tried: In smb.com, add a line reading
smb ports = 139
which I hoped would tell it just don't reply on port 445 at all. This did
Next thing I tried, rather a kludge,
iptables -I INPUT 1 -p tcp --dport 445 -j DROP
Hey guess what? I haven't had a single incidence of the error since.
My explanation, as near as I can figure out, of what the rule does:
iptables ; firewall / packet filter
-I INPUT 1 ; Insert into chain "INPUT" as rule #1
-p tcp --dport 445 ; a rule for packets whose protocol is tcp AND
destination port is 445
-j DROP ; if matches rule, Jump to target "DROP"
The predefined target DROP is not another chain but actually means throw
the packet away.
I'm allowing port 139 through (by default) instead of 445 because I still
have the odd Win98 machine laying about.
That's my story, and I'm sticking to it.
