Hi everyone,

I'm fairly new to socket programming and I'm trying to make a program
that will sniff packets on a LAN network and display them graphically.
I've heard of a packet capture library called 'libcap'. I would like to
know if the functions in this library are those described in many FAQ's
as socket() and bind() etc., or are they something different. I'm
running SuSE Linux 6.4 and there no man page for it and I can't find any
documentation on the web. Can anyone tell me where to get documentation
for libcap, or any other library that performs similar functions.

Thx

P.S Would libnet (www.packetfactory.net/libnet) help?

You probably want libpcap and tcpdump. See http://www.tcpdump.org

They're something different. Socket(), bind(), are the functions used for
normal network communications.

See the Raw Sockets FAQ, which can be found at www.faqs.org.

Thanks guys, I think I'm a little clearer on what I need to do now.
