Building a Virtual Cluster with Xen

Post date: September 28, 2006, 04:09 Category: Emulation Views: 7445 Comments
Tutorial quote: It is a common practice to have development and test servers for each production server, so that you can experiment with changes without the fear of breaking anything important, but this is usually not feasible with clusters. So how do you try that new version of your favorite program before committing it to the production cluster? A cheap and convenient possibility is to build a virtual cluster.

Thanks to the Xen virtual machine monitor, you can create a number of virtual machines, all running simultaneously in your computer, install different operating systems in them, or just different configurations, and connect them via (virtual) network cards. Xen is a terrific tool for building virtual Beowulf clusters. It can prove useful when learning or teaching about clusters or for testing new features/software without the fear of causing major damage to an existing cluster.

Backing Up and Restoring Using the cpio Command in Linux and Unix

Post date: May 26, 2006, 18:05 Category: System Views: 2696 Comments
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.

Connecting to a Wireless LAN with Linux, Part 1

Post date: April 13, 2005, 19:04 Category: Hardware Views: 3575 Comments
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.

Building an LDAP Server on Linux, Part 2

Post date: April 15, 2005, 17:04 Category: Network Views: 3601 Comments
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.
