I think, I should change my question. I was reading a document regarding
troubleshooting a distributed application. Their recommendation was to setup
side by side traces or simply, 2 sniffer on both ends, 1 on the client side
and the other 1 on the server side. Assuming I have done this, what is my
next step to figure out bottlenecks in WAN or application?
Thanks,
Neil

Ethernet uses a CRC,

Hey guys,
I'm looking for a way for finding crc errors in TCP header just like how
it was mentioned here,
http://www.networkuptime.com/tips/crc_in_tcp/index.html
Unfortunately, it is not for Ethereal. So how do we search CRC problems
in Ethereal? Can someone walk me through please?
Are you looking for Ethernet checksum information or TCP crc info?
Unless you have a) a hub based network or b) Cabletron switches, you will
not be able to capture Ethernet checksum issues. All the switches that I
worked with will not pass along damaged Ethernet frames. Cabletron was
the exception.
