This section lists a few useful sources of information where you can find additional information about the Linux network architecture.
Magazines
The Linux Magazine (http://www.Linux-mag.com) is probably the best-known Linux magazine. It features articles about all issues that are of interest when you deal with Linux. Of special interest is the Kernel Corner column, which regularly publishes articles about the architecture and implementation of components of the Linux kernel most of them by developers themselves.
Linux Focus (http://www.linuxfocus.org) is an online magazine publishing articles in many different languages. It also includes a Kernel Corner.
The Linux Gazette (http://www.linuxgazette.com) is another online magazine dedicated to Linux.

Other Information
Howtos include a lot of information about different Linux issues. Most deal with the configuration and installation of various Linux functionalities. Especially for the Linux kernel, there are also a few howto documents for example, how to use locks in the kernel [Russ00b], and general information on hacking in the Linux kernel [Russ00c]. Of course, we should not forget to mention the networking howto, which includes a wealth of tips and information about configuring the network functionality in Linux [Drak00].
The source code of the current kernels is found at ftp.kernel.org. There are also mirrors of this FTP server, a list of which can be found at http://www.kernel.org/mirrors/.
Information about components and drivers of the Linux kernel are also included directly in the source code of a kernel version, in the Documentation subdirectory. In addition, the file Documentation/kernel-docs.txt includes a list of current information about the Linux kernel for example, documentation, links, and books. (It's worth taking a look at this file!)
