In the 1st part of the IP Routing series, we learned the fundamentals of Linux IP Routing. Route command is used to show/manipulate the IP routing table. It is primarily used to setup static routes to specific host or networks via an interface. In this article we will see how to manipulate the routing tables [...]
Proc file system reflects the current state of Linux kernel. The current state of kernel could represent various information like the processes running on it, the hardware information, the network information etc. So this system is designed in a way that all this information can easily be accessed by the user level processes. We also [...]

Probably you know how to check the existing routes (or even add/modify routes) on Linux using route or netstat command. You migh’ve done that without understanding much about how IP routing works. This article will help you understand the principles behind the IP routing and how it works. This is the 1st part in the [...]
In the part I of the Linux Threads series, we discussed various aspects related to threads in Linux. In this article we will focus on how a thread is created and identified.
