Description Brian Goetz 2004-11-16 13:06:07 UTC
Client system: Windows XP SP2
Server system: RHEL WS 3 (Taroon update 3) with Samba 3.0.7-1.3E1
Network: no windows domain -- ad-hoc network with 4-5 nodes, one server, 
several clients.  

Problem: When accessing a Samba volume from the affected client system, there 
are _long_ delays in opening any folder that has not been recently opened.  

An ethereal dump reveals that every time this XP client sends an 
NTLMSSP_NEGOTIATE request, there is a 10s delay before the server responds.  As 
there can be one or more of these requests in opening a folder, it can take 10, 
20, or more seconds to open a folder the first time.  Dump attached.  

Problem exists whether using NetBT or straight TCP.  

Problem exists on 3.0.7 and 3.0.0 (RPM), and presumably intermediate releases.  
Problem does _not_ exist on 2.2.9 (built from source.)  

Problem does not exist with Win2K client against 3.0.x servers.  

The performance is such that the file server is effectively unusable.  

Packet dump attached -- let me know what more information / experiments are 
needed.  In the dump, the server is, and the client is .101.

Problem confirmed on build of 3.0.8 from source; not introduced by RedHat when 
building RPM.

We really need to see server-side logfiles, at a level of detail (including
timestamps) that shows which part is stalling.
