This is a small home LAN - two boxes running Mandriva 2005LE, four assorted 
windows boxes and one box running Mandrake 10.0,  with samba giving file 
and print services to the rest.  The box called 'david' is the samba client 
that is my workhorse, and on which I am seeing the problem (although it is 
present on the other Mandriva box too).  The server runs samba 3.0.10 and 
client is running samba 3.0.13, though I have tried installing 3.1 without 
seeing any difference.  I have reverted to 3.0.13.

I am seeing huge delays when transferring files direct from an application.  
Small gnumeric files save instantly on the local filesystem, but take 1.5 
minutes over the lan.  OOCalc has been unable to save the same spreadsheet 
at all, saying that access is denied.  Printing from OOWriter is 
exceptionally slow, though this is never as bad from any other application.

Always possible.  My main problem, though, is in saving files across the 
lan, direct from apps like gnumeric.

Shorewall is not installed on this (the client) box, and windows boxes can 
save correctly, indicating that shorewall on the server is working 
correctly.

Normally the shared directories are 770, but I have already tested them with 
777.

I now have further information.  With the help of a more proficient user I 
have managed to collect the following evidence from ethereal running on the 
server:

1170 38.414157   192.168.0.70          192.168.0.30          SMB      Trans2 
Request, SET_PATH_INFO, Path: \Documents\Spreadsheets\.gsf-save-vkxojF
   1171 38.414318   192.168.0.30          192.168.0.70          SMB      
Trans2 Response, SET_PATH_INFO
   1297 68.409645   192.168.0.70          192.168.0.30          SMB      
Trans2 Request, QUERY_PATH_INFO, Query File Unix Basic, Path: 
\Documents\Spreadsheets\.gsf-save-vkxojF
   1298 68.410110   192.168.0.30          192.168.0.70          SMB      
Trans2 Response, QUERY_PATH_INFO
 
This clearly shows the 30-second delay.  The save ends with a Close Response 
at 68.538988 yet it is 90 seconds from the start before I get control back.

I'll gladly run any more tests required, but as a newbie to ethereal I shall 
need very specific instructions.
