LDAP Authentication In Linux
This howto will show you howto store your users in LDAP and authenticate some of the services against it. I will not show howto install particular packages, as it is distribution/system dependant. I will focus on “pure” configuration of all componenets needed to have LDAP authentication/storage of users. The howto assumes somehow, that you are migrating from a regular passwd/shadow authentication, but it is also suitable for people who do it from scratch.

m0n0wall
m0n0wall is a project aimed at creating a complete, embedded firewall software package that, when used together with an embedded PC, provides all the important features of commercial firewall boxes (including ease of use) at a fraction of the price (free software).
m0n0wall is based on a bare-bones version of FreeBSD, along with a web server, PHP and a few other utilities. The entire system configuration is stored in one single XML text file to keep things transparent.
m0n0wall is probably the first UNIX system that has its boot-time configuration done with PHP, rather than the usual shell scripts, and that has the entire system configuration stored in XML format.

Setting up a server for PXE network booting
Remote Network Boot via PXE
Let’s say you’re responsible for a network of 100 computers shared by students. What do you do if one of those computers starts acting funny? If you’re like me, you’ll just do a clean install of the operating system. But that’s a lot of work, especially if you have to do it several times a week. Fortunately, most PCs sold since 2001 follow the PC99 guidelines from Intel and Microsoft, which among other things says that new computers with Ethernet interfaces must implement two useful features: wake-on-LAN and network boot.
Public key authentication with ssh
Introduction
This LinuxAnswer describes how to set up public key authentication with ssh{1}.
It will include all sub components like scp too.
I will refer to the client machine{2} as the “client” and the server machine{3} as “server”

Ez-12 Parabolic Reflector Template
Note: If printed at the download size you will see about 9 dBi of gain. If you double the size of the image before you print it you will see about 12 dBi of gain. If you place two reflectors on an AP with two antennas you will see an additional increase in performance.

Data Center Fabric Architectures
This article describes five classes of fabric architectures based on how they use management, control and data (forwarding) plane. Throughout the article we’ll use the generic term switch to describe a forwarding device that can forward either Ethernet frames (layer 2 switch) or IP datagrams (layer 3 switch).
