It's the Linux way to capture frames at the link layer and inject frames into the link layer, directly bypassing all the intermediate protocol layers. As such, it cannot receive or transmit anything unless you bind one or more real devices to it. Your editor had been told that O'Reilly had a book on the networking stack - a sort of companion to Understanding The Linux Kernel - in the works. Contribute to nikita-b/awesome-linux-internals development by creating an account on GitHub. (Almost all Linux machines do implement networking, even stand-alone machines, if only to use the loopback device.) When the kernel finishes loading itself, it runs a set of common but system specific utility programs and reads configuration files, several of which establish the computer's networking capabilities.

In principle, each protocol provides a function to get a reference to the header of that protocol within a received packet. From Understanding Linux Network Internals: In Linux, a bridge is a virtual device. As such, it cannot receive or transmit anything unless you bind one or more real devices to it. After reading last article, somebody asked me, since a bridge is a L2 device, why we see an IP address with it when we run ifconfig br0? If youve ever wondered how Linux carries out the complicated tasks assigned to it by the IP protocols or if you just want to learn about modern networking through real-life examples Understanding Linux Network Internals is for you.
