SAMBA digest 1690

[Dave Cottle]

Hi all,

the local unix guru & myself (the neophyte) have been samba'ing 
merrily away, but run into two problems, which I can't seem to 
resolve (help wanted, reply directly preferred to keep list volume 
down :-). Any help or pointers (rtfm etc) appreciated.

(I've enclosed the smb.conf at the end of the msg)

1.
Browsing - I need to use two NT servers for browse functionality & I 
can't get the samba server to appear. The end of the line is to get 
the samba server to use NT's domain authentication instead of its own 
unix end.

2. 
guest connections _without_ having to enter a pwd under Win95, or NT. 
Should just be able to "net use" to the samba server (had to use an 
lmhosts entry to get around the non-browsing problem).
3.
most stuff works just fine, but one of the jobs we do frequently is 
update files from a core which exists on a Novell server. I use 
robocopy v.171 (NT 4.0 reskit update 2) to do this. It causes a 
problem when copying to/from a samba server:

robocopy to a non-existent dir works OK. 
subsequent robocopy to update this dir fails at the first 
sub-directory. The smbd process then dies, and is recreated shortly 
afterwards (when the next copy is tried).
each subsequent robocopy to update this dir fails at the 
_next_ sub-directory.

Our UNIX guru supplied the following info:

If you're going to post a message to the samba mailing list, there is 
a consistency to the problem. I've tried the robocopy a number of 
times. Each time the copy stops at the directory after the one it 
hung on the previous time. There is a timeout period of approximately 
73 seconds. I timed it several times.  That's quite a strange number 
if you ask me. Below are a couple of traces, one being the network 
traffic the other a truss. The network traffic shows the PC sending a 
message to cantua, but no response from it. That's the 
cctrxc.canterbury.ac.nz -> cantua_fddi line of the network trace.

The truss shows that the smbd process sent a message to the PC but
received no reply. Its shows a write, then it polls but doesn't
receive anything so never does a read.

I've tried it on both the FDDI and ethernet interfaces
and it makes no difference. The smbd process does not exit
until the end of the 73 second time out period.

It appears to me that somehow the smbd process is not getting
the last message from the PC, but I have no idea where it's getting
lost.
