• [run2tech] Linux System Administration: First Tasks | Linux Journal #
  Linux system administration has a place of its own in the hierarchy of information technology specializations. Some people excel in special areas of free software technology but haven't needed to learn system administration. For example, you may specialize in configuring e-mail or writing applications using Apache and MySQL. You may focus only on Domain Names Services and know esoteric ways of setting up servers on provider lines that frequently change IP addresses. But if I asked you to babysit a busy server or servers, you might not have the temperament or have learned the plethora of skills required to do so.

  'This is probably the first thing you want to know. When a distribution is packaged and delivered to clients, it is designed to be fully compatible with most of the computers available in the market. This is a very heterogeneous set of hardware (hard disks, video cards, network cards, etc.). So distribution vendors like Red Hat, SuSe, Mandriva and the rest of them choose some conservative configuration options to assure a successful installation.
  
• [MySQL &PostgreSQL] Linux Today - HowtoForge: How To Set Up A Load-Balanced MySQL Cluster #
  'This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster). 'In this document I use Debian Sarge for all nodes. Therefore the setup might differ a bit for other distributions. The MySQL version I use in this setup is 5.0.19. If you do not want to use MySQL 5, you can use MySQL 4.1 as well, although I haven't tested it...'
  
• [Unix&Linux Platforms] About Mono - Mono #
  Mono, the open source development platform based on the .NET framework, allows developers to build Linux and cross-platform applications with improved developer productivity. Mono's .NET implementation is based on the ECMA standards for C# (http://www.ecma-international.org/publications/standards/Ecma-334.htm) and the Common Language Infrastructure (http://www.ecma-international.org/publications/standards/Ecma-335.htm).
  
• [run2tech] Linux.com | Running .Net applications on Linux with Mono #
  Mono is an open source project (sponsored by Novell) that allows you to run .Net applications on Linux (as well as Unix, Mac OS X, Solaris and even Windows). To obtain it, go to the Mono download page and find the version you need for your distro.
  
• [run2tech] Linux.com | How to configure a low-cost load-balanced LAMP cluster #
  A LAMP cluster is not the Beowulf kind of cluster that uses specialized message-passing software to tackle a computation-intensive task. It does not cover high availability features, such as automatic failover. Rather, it is a load-sharing cluster that distributes Web requests among multiple Web and database servers while appearing to be a single server.

• [IIS and Web Administration] Always set the 'applicationName' property when configuring ASP.NET 2.0 Membership and other Providers #
  You develop an ASP.NET 2.0 application locally using the new ASP.NET 2.0 Membership, Roles or Profile features. You create several new users and everything works fine. You then copy the application to a remote server (or even another directory on your local server) and run the application. For some reason it appears that you are able to connect to your membership database just fine – but when you try to login it doesn’t let you. It doesn’t throw a connection error, but rather when you attempt to login you get an error message that says something like: “Login attempt unsuccessful, please try again.”
