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.

I am trying to build a socket to retrieve the ethernet packets from ecu. When i run my code on windows there is no problem and the code runs correctly. But when i run my code on Linux it gets stuck at s.recv(65565). I have already set static ip in /etc/network/interfaces as follows: iface eth0 inet static address 220.127.116.11 netmask 255.255.255.0 gateway 18.104.22.168
I tried a simple code of socket on raspberry pi. but it still gets stuck at s.recv(65565). I also tried to implement the program using multicast. but the problem is that when i create a socket for icmp protocols then I could see the data from the ECU after using command "ping -I echo 22.214.171.124" in another terminal. (where 126.96.36.199 is the multicast address) But when I change the socket protocol type to udp, tcp or raw then it again gets stuck at s.recv().
Imp: When i run the "netstat -s" command in terminal then i could see that there are 0 messages received for udp and tcp. But in Wireshark i could see the udp messages from ECU. Is linux killing all the udp and tcp packets ? How should i solve this ?
(complete setup is connected as: ECU ---> Media converter ---> Raspberry Pi. There is no LAN, no firewall, no internet)
