Linux VMware and Xen Management with BixData
Post date: November 16, 2006, 14:11 Category: System Views: 1022 Comments: 0
Tutorial quote: BixData is a system, application, and network monitoring tool which allows you to easily monitor nearly every aspect of your servers. The newly released version 2.6 is the only application that has the ability to control both Xen and VMware virtual machines. You can control both VM Hosts (the computer that's running the VM software) and VM Guests (the virtual machines running on the hosts).
Linux Backing Up and Restoring Using the cpio Command in Linux and Unix
Post date: May 26, 2006, 13:05 Category: System Views: 938 Comments: 0
Tutorial quote: The cpio command is one of the most commonly used Linux back up tools.

The cpio command has two unusual features

Unlike tar , in which the files to back up are typed in as part of the command, cpio reads the files to work with from the standard input (in other words, the screen).

This feature means that cpio must be used as part of a multiple command or with a redirection pipe. Examples of this usage are shown in the tables below.

cpio must always be used with one of three flags. Flags are options that set the mode in which the command runs. Only one flag can be used at a time, and it must come before any other options. In addition, the choice of flags limits the options that can be used. Each flag also has a gnu option that can used in its place. The gnu option gives a convenient name for each flag: extract, create, and pass- through.
Linux Xen: How to Convert An Image-Based Guest To An LVM-Based Guest
Post date: April 19, 2009, 05:04 Category: Miscellaneous Views: 731 Comments: 0
Tutorial quote: This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it is often better to use LVM. Also, LVM-based guests are easier to back up (using LVM snapshots).
Linux Connecting to a Wireless LAN with Linux, Part 1
Post date: April 13, 2005, 14:04 Category: Hardware Views: 1190 Comments: 0
Tutorial quote: Wireless hardware for Linux is a moving target. The wireless network adapter that worked fine with Linux yesterday may be released with an unsupported radio chipset today, and with no indication of the change. So buyer beware--always confirm the chipset before you buy. The good news is a lot of wireless adapters have native Linux support, and for those that don't, the NdisWrapper utility lets you use the Windows drivers on your Linux box.
Linux Building an LDAP Server on Linux, Part 2
Post date: April 15, 2005, 12:04 Category: Network Views: 1112 Comments: 0
Tutorial quote: Welcome back! In Part 1 we learned basic concepts of LDAP and the uses for an LDAP server. Today we'll install and configure an OpenLDAP directory.

A quick note before we get started: this is LDAP 101. We are not installing any kind of encryption or strong authentication; we'll get to that in part 3. In my experience, learning LDAP in small chunks works best. (Then again, perhaps I'm just a bit dim.) So sit back, strap in, and keep your fingers away from the training wheels.

"The wise sysadmin will consult the documentation for their distro; it's quite possible that OpenLDAP will be packaged and ready to go in a pleasing manner (or ready to go in an odd manner--you never know). I'm all for easy--if your particular distribution provides an easy way, use it. RPMs can also be obtained from rpmfind.net, which thoughtfully lists all the required additional packages.

"Debian of course goes its own merry way. apt-get does the job just fine; the tricky bit is finding out the package names. Debian users want ldap-utils; slapd, which is OpenLDAP; and libdb4.1, to get the Sleepycat DB. These three components are enough to get you up and running. apt-get will walk you through a minimal configuration and will automatically start up slapd, the LDAP server daemon.

Ubuntu Load-Balanced High-Availability Web Cluster With 2 Xen Servers On Ubuntu 8.04
Post date: October 12, 2008, 07:10 Category: Installing Views: 962 Comments: 0
Tutorial quote: In this howto we will build a load-balanced and high-availability web cluster on 2 real servers with Xen, hearbeat and ldirectord. The cluster will do http, mail, DNS, MySQL database and will be completely monitored. This is currently used on a production server with a couple of websites. The goal of this tutorial is to achieve load balancing & high availability with as few real servers as possible and of course, with open-source software. More servers means more hardware & hosting cost.
