Hey All,


I am trying to solve a networking problem between my Windows Desktop and 
a 32 bit Ubuntu 10.04 Server.  I believe that somewhere in the network 
stack traffic is being modified in a hard to detect manner.

The problem I noticed came from when I tried to do a packet capture on 
both Linux (using tcpdump) and on Windows (using Wireshark).  I 
attempted to download a file from an Apache server running on the linux 
box to the Windows box.  Recording the traffic from linux seemed to show 
that the transit worked, however from the Windows side Wireshark 
reported a number of Dup Acks and many smaller packets with slightly 
different data in them.


I have flushed all my iptables rules on the linux box so I am not sure 
what could cause the discrepancy.  I can include the pcap files if needed.

Any help is appreciated,
Bill
