Automatic And Up-To-Date Fedora 9 Installations With Kickstart And Novi

Post date: October 30, 2008, 12:10 Category: Miscellaneous Views: 3879 Comments
Tutorial quote: Kickstart allows you to do automatic Fedora/RedHat/CentOS installations. This is useful and time-saving if you have to deploy tens or hundreds of similar systems (e.g. workstations). Kickstart reads the installation settings from a Kickstart configuration file. The problem with Kickstart is that it usually uses the distribution's packages from the time the distribution was released, i.e., it does not consider updates which means you would have to update each system manually after the Kickstart installation. This guide explains how you can do up-to-date Kickstart installations with the help of a tool called novi.

A much easier way to install Ubuntu on a USB device (Stick or Hard Disk)!

Post date: June 1, 2008, 21:06 Category: Software Views: 4890 Comments
Tutorial quote: This tutorial will explain A much easier way to install Ubuntu on a USB device (Stick or Hard Disk).I was reading How to install Ubuntu Linux from USB Stick posted a while ago, and found it to be quite some work to get Ubuntu working on a USB stick. Besides, having to prepare your USB device, creating a separate partition on it which will be more or less “useless” after the installation, giving up 750MB of space?

NFS over CIPE-VPN tunnels

Post date: May 23, 2005, 16:05 Category: Network Views: 3440 Comments
Tutorial quote: The Network File System (NFS) is a standard protocol for sharing file services with Linux and Unix computers. It is a distributed file system that enables local access to remote disks and file systems and is based on the client\server architecture. Although easy to configure, it is typically used only to transfer data over an intranet or LAN because of its transparency and security potholes when exposed to the risks of the Internet. However, it still can be employed -- without compromising security -- to share files over the Internet by configuring it to run on a Virtual Private Network (VPN) connection. This article will show you how to set up NFS to run over a CIPE-VPN connection between two Linux systems.

How To Install Qmailtoaster (CentOS 5.3)

Post date: June 19, 2009, 10:06 Category: Installing Views: 8210 Comments
Tutorial quote: Qmailtoaster is a project that aims to make the installation of Qmail onto RPM based systems a snap. All of the packages are distributed in source RPMs so building the packages for your particular distro and architecture is as easy as running a script or a simple command for each package. The RPMs have all of the needed and commonly asked for patches included so you can have a mail server up and running in about an hour. When it's all complete, you'll have a full Qmail mail server installation ready for just about anything. I personally run Qmailtoaster servers for other companies and ISPs who have tens of thousands of users on their systems.

Storing Files/Directories In Memory With tmpfs

Post date: December 9, 2008, 12:12 Category: Miscellaneous Views: 3598 Comments
Tutorial quote: You probably know that reading from RAM is a lot of faster than reading files from the hard drive, and reduces your disk I/O. This article shows how you can store files and directories in memory instead of on the hard drive with the help of tmpfs (a file system for creating memory devices). This is ideal for file caches and other temporary data (such as PHP's session files if you are using session.save_handler = files) because the data is lost when you power down or reboot the system.

High-Availability Storage With GlusterFS On Debian Lenny

Post date: June 9, 2009, 11:06 Category: Installing Views: 4511 Comments
Tutorial quote: This tutorial shows how to set up a high-availability storage with two storage servers (Debian Lenny) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Debian Lenny as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 servers with SATA-II RAID and Infiniband HBA.
