Network Packet Capturing Over Linux 2.4

Hello,

I am a beginer at network programing. I have done Kernel Module
Programing before. i wanted to enquire about that how a network packet
can be captured on Linux 2.4 System? How can the packet be stored
temporarily somewhere and its information can be accessed like source
address, destination address etc? Currently I am reading Computer
Networks By Tenenbaum and some CCNA Meterial.
Please guide me from the scratch. Also suggest reading material.

"libpcap is a system-independent interface for user-level packet
capture. libpcap provides a portable framework for low-level network
monitoring. Applications include network statistics collection,
security monitoring, network debugging, etc."

application. which I am unable to execute. I have checked file
permissions. So how to use the library?? Or else where to find it in a
better form?? I downloaded it from www.tcpdump.org

Please help me with Installation and usage of libpcap library?

I saw the program on the above site
it needs to be compiled as gcc ldev.c -lpcap
but the libcap is not installed as it reports on the consoleBut when I
try to install it via an RPM it reports that it is already installed.

Please help me with Installation and usage of libpcap library?
