How to run packer sniffer while transfer data using TCP

Hi,

Can you help in urgent basis...

Pls tell how to run the packet sniffer while transfer data using TCP...

Can u tell me in details Plssssssssss.......

nnbnbHuh? Try reading this en.wikipedia.org/wiki/Packet_sniffer . It has some links to various open source and commercial sniffers. It also has links to FAQ's and How-To's.

Also, if your looking for good caputuring software, check out Ethereal and tcpdump. Both are excellent programs.

Try out ethereal... Its a free software with the largest number of protocols supported...

This will answer your requirement and in addition will open the door for greater network understanding

Do remember to install winpCap before installing ethereal..

Thanks
Paul

Hi,

If u r using linux or fedora, go for the man page of tcpdump options available. From that options u can filter the packets you are looking for.

For ex. basic cli is


host#] : tcpdump -i eth1

here i - interface. If u setup to flow the packets through eth1 you can use this command to filter packets in eth1 interface.
