Can you load it in your ethereal binary ? Also, can you remind me of the issue we're tracking here :-) (Sorry, I'm concurrently tracking a lot of stuff, and context in an email helps).

Ok, after a quick crash course in ethereal including compiling and installing it, Here is the capture, This log has been filtered by time before and after where the drop out occured as well as source and dest IP's (frame.time_relative >= 343 && frame.time_relative <= 347.2) && (ip.src == 10.0.0.224 || ip.dst == 10.0.0.224) Then saved (this info here for making sure I didnt screw up the logs) The error occures @ time 2 seconds after beginning of capture attachment available upon request, the list wont let me post it and I dont have a reliable space to throw it up on the net Andrew -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba

This will help to debug the problem. Thanks, Jeremy. -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba

What NICs? What HUBs? Are you running in duplex mode? What error rates on the ethernet interfaces? What collision activity on the HUBs? This does not sound like a Samba problem. - John T. -- John H Terpstra Email: [EMAIL PROTECTED] -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
