[plug] Smb Network Probs. MTU???

[Tim White]

When attempting to transfer files over smb the packets slow down to a halt 
with the time between packets doubling each time. The MTU of eth0 is 1500 
and when set to 100 smb finally works (as much as I can see.)
This slow down doesn't occur for Internet traffic only for smb. Both net 
and smb traffic are from the windows gateway to my workstation. Last time 
this was a problem it also effected FTP. NFS traffic between my debian 
server and my workstation is fine.
The workstation is Knoppix 3.2 (C'T)
If anybody knows a fix for this other than MTU then please tell me. Does a 
lower MTU slow down other traffic? Also how can I set the MTU to be 
permanently 100.
This slow down also occurs using smbclient to copy files. In a normal 
smbmount|smbclient session I can cd to the directory and then i can 
possibly copy a few bytes before traffic halts. Looking at the output of 
ifconfig and observing the network graph in gnome the packets get further 
and further apart and ifconfig logs an error each time a line shows on the 
graph (showing activity)
Looking the the logs (under /var/log) i can't see any error messages that 
are associated with it and using ethereal i can't work out what's happening 
(lots of lovely non descriptive fragmented smb talk) this may be due to the 
fact that it is knoppix as i can't find an errors log like i can on my 
debian server (3r1)

p.s. Why can't Eudora get a dictionary with all the nice linux words??? 
smb, ifconfig, debian, var, NFS, mtu ...
