Hi everyone I have two machine connected with a crossover cable, I am looking for a C program to collect the data in the reciever machine. I think such these programs are ready and free on the net but I failed to get them. If anybody knows a specific program to do that, please provide me. thanks a lot
Code: tcpdump is a standard line oriented packet sniffer/dumper, or you could use Wireshark (both Linux and Windows version) if you want nice graphical representation and filtering. tcpdump has a lot of filtering options too. See Code: man tcpdump
but that program is not open source code, it is closed. I found out tcpdump.8.gz and tcpslice.gz are located in /usr/share/man/man8. I can decompress any of them if I would get the source in C, but tar command does not work correctly here, may be because the file is 8.gz not tar.gz !!
Both programs are open source and they are included in Debian/Ubuntu distributions. Maybe they are in restricted, but they are certainly freely available. the /usr/share/man/man8/tcpdump.8.gz is part of the man pages. You cannot use that. 1st install the programs with Code: apt-get install tcpdump and then try Code: man tcpdump .
