Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

tanmoy:/home/tanmoy/Desktop/tdas # gcc appdev.c -lpcap
appdev.c: In function ‘main’:
appdev.c:63: warning: passing argument 3 of ‘pcap_loop’ from incompatible pointer type
tanmoy:/home/tanmoy/Desktop/tdas # ./a.out
Device is opened.
Filter is compiled.
first of all I didn't gave u any solution. so definitely, the problem will persist. The purpose why I posted is to have a look at the output. some times, the buffer won't get flushed and the output won't get displayed. Because of that reason, I asked you to keep the \n there so that the output will be get displayed on the screen.
can you please tell me what the output you got from that printf?
then I shall try some thing.....
