Amahi Home Server - Making Home Networking Simple The 9 Best Low-Cost RADIUS Servers Need a Remote Authentication Dial-In User Service (RADIUS) server for your authentication, authorization and accounting (AAA) needs? You can spend thousands on RADIUS solutions, but there are also a number of lower-cost alternatives. These solutions are especially useful for smaller organizations that may only be using it for a single purpose, such as to implement enterprise Wi-Fi security with 802.1X authentication. Many, however, can also be used for other AAA purposes. If you're running a Windows Server, keep in mind you already have RADIUS capability. For those without a Windows Server, or those whom require more functionality and customization, consider these solutions: 1. This free and open source software is one of the most popular RADIUS servers in the world. 2. FreeRADIUS.netis a free Windows distribution of FreeRADIUS, designed to work on Windows XP. 3. TekRADIUSruns on Windows and offers a GUI. 4. 5. 6. ZeroShell is another router OS, but it is open source and completely free.

Building Your Own Super Computer Building Your Own Super - Building a Linux Cluster ( 4 ) Linux clusters are generally more common, robust, efficient and cost effective than Windows clusters. We will now look at the steps involved in building up a Linux cluster. For more information go here . Step 1 Install a Linux distribution (I am using Red Hat 7.1 and working with two Linux boxes) on each computer in your cluster. Usually, one node is designated as the master node (where you'll control the cluster, write and run programs, etc.) with all the other nodes used as computational slaves. Our cluster is private, so theoretically we could assign any valid IP address to our nodes as long as each has a unique value. If you already have Linux installed on each node in your cluster, then you don't have to make changes to your IP addresses or hostnames unless you want to. Finally, create identical user on each node. Step 2 We now need to configure rsh on each node in our cluster. Master DevArticle Slave DevArticle
