installing libcap

I faced lot of problem in installing libcap (library for sniffing packet). You can easily install it in ubuntu by installing the package libpcap0.8-dev.

#sudo apt-get install libpcap0.8-dev

and during compilation of any program using pcap.h
 compile it

#gcc prog.c -lpcap -o prog
