Well there are many ways that you can format data, including tcpdump data. If you are looking for some thing quick and dirty you can simply run the output manually through grep to sort out the basic lines you want and play with cut, awk & sed to break it down to the details. But I gather that you are likely looking for something a bit more polished to play around with. One of the best options to work with tcpdump info is ethereal.

http://www.ethereal.com/

The good news is that it is available for free and runs on Linux, Unix and Windows... Hard to beleive that so few can have so much fun.

hello sir
we first used ethereal , when we transfer large file size the system gets loged off, i don't what is the reason, that's why we used tcpdump, but now we are finding it difficult to calculate the time required to transfer each packet, that's why we need something else like ethereal,
if any idea please do inform us

thanks

I am sorry I am not excatlly sure that I am on the same page with you at the moment. I gather that you have attempted to use ethereal but it is crashing on you while you are attempting to perform file transfers? Are you working on a network segment that has a lot of traffic going across it? Or are you working with a system that is very low in resources such as RAM?

Or are you simply not seeing the type of data that you are hoping to see when using ethereal?

Actually we testing our Router by sending data with large file size
that's why it is logging off when we are using ethereal and we opted for tcpdump
but we are finding it difficult to collect the details
