Gentoo

Enterprise Volume Management System Mini How-To

Post date: April 13, 2005, 20:04 Category: System Views: 4427 Comments
Tutorial quote: Here is a rough write-up on how I installed Gentoo 1.4_rc1 on EVMS, with the exception of the root partition. If you choose so, see the EVMS Howto for instructions on how to mount your root file system on an EVMS volume. I felt the hassle of dealing with a EVMS (or LVM, for that matter) root outweighs its advantages.

This is a very basic setup I used for my laptop. I only needed it so I don't have to worry about getting the partition sizes right from the beginning and to be able to adjust them with ease in the future. I've been using LVM with success but I couldn't find a way to resize the volume group itself. This, the fact that afaik there is no support for LVM in kernel 2.5.x and a new laptop needing a fresh installation made me try EVMS.

Mastering the Enterprise Volume Management System

Post date: April 13, 2005, 19:04 Category: System Views: 3332 Comments
Tutorial quote: The Enterprise Volume Management System, or EVMS, is a disk, partition, and file system manager for Linux that claims to be a comprehensive tool for all disk management tasks. I ran across EVMS and found the idea appealing, so I decided to try it out. I've been working with it for a couple of weeks now, and this article describes what I found.
Mepis

Mepis + apt = Working On Easy Street

Post date: April 13, 2005, 19:04 Category: System Views: 6897 Comments
Tutorial quote: My reasoning for combining the traditional Debian apt command with Mepis was speed and efficiency. Also, in the fine tradition of open source, I could choose to use the command line instead of the Kpackage or Mepis System Center package management screen. This is a good way to learn about Debian systems that builds confidence for new users right off the bat.

Let's see how apt works with Mepis.

Keeping Fedora Up to Date with Yum

Post date: April 13, 2005, 01:04 Category: System Views: 5138 Comments
Tutorial quote: Yum is an automatic updater and package management tool for rpm based systems. Yum automatically computes dependencies and figures out what steps need to occur in order to install packages. It makes it much easier to maintain groups of machines without having to manually update each one using rpm.

Using a jail as a virtual machine

Post date: April 12, 2005, 18:04 Category: System Views: 4371 Comments
Tutorial quote: This article shows you how I created a jail for the OSW website. It runs in a jail on the same system as this website. I originally did this install back in November 2003 and the notes from that session form the basis of this article. I have need to recreate the jail now as we recently had an HDD failure.

A jail is useful for many purposes. In my case, I wanted to give the OSW project a place to run their websites, mailing lists, etc, but at the same time keep them isolated from the rest of the machine. In short, it gives them a virtual machine, and it gives me peace of mind knowing that I have less to worry about with respect to the rest of the machine.

Debian Kernel Compile Howto (Kernel 2.6)

Post date: April 12, 2005, 18:04 Category: System Views: 4138 Comments
Tutorial quote: In some cases you might want to compile your own kernel that suits your needs better than the standard kernel that comes with your distribution. I will describe how to do this on a Debian machine. Please note that this tutorial is for kernel 2.6 only!

Setting the Clock on Linux

Post date: April 12, 2005, 17:04 Category: System Views: 2928 Comments
Tutorial quote: There are 3 protocols dealing with time: NTP (port 123), Time (port 37), and Daytime (port 13). If you're connecting to the Internet periodically, then synchronizing your clock when you dial up or from crontab is good enough. This applies also to most Linux machines at home or at work, even if they are connected all the time. Here is a short tutorial on how to set your clock using these 3 protocols.
Debian

An apt-get primer

Post date: April 12, 2005, 17:04 Category: System Views: 3399 Comments
Tutorial quote: If any single program defines the Debian Linux project, that program is apt-get. apt-get is Debian's main tool for installing and removing software. Working with the .deb package format, apt-get offers sophisticated package management that few Red Hat Package Manager RPM-based distributions can match.

Besides the convenience, an advantage of apt-get is that it reduces the chances of falling into dependency hell, that limbo where software installation fails for lack of another piece of software, whose installation fails for lack of another piece of software, and so on. If you know how Debian's archive system works, and how to choose the sources that apt-get uses, and use a few precautions in your upgrades, then the chances are that dependency problems will never bedevil you. Should you descend into dependency hell anyway, apt-get offers useful tools for climbing out of it.
