Notes taken from another blog post on installing xen 3.2 on Lenny.

Some of you might know Nagios, some of you might not. Nagios is a network and server monitoring system. It’s open source and widely used (at least that’s my impression). I now use Nagios to monitor all of my network, and my server it self.

My daily duties as a sys admin today included installation and configuration of SuPHP. SuPHP is an apache dynamic module for executing PHP scripts with the permissions of their owners.

At my place of employment, we just finished our debian upgrades. Overall I have huge respect for debian and the apt package tool. Overall the migration from etch to lenny across several servers was easy, except for one back.

I’ve been trying this already several times over the last three months, but always failed to build the latest Valgrind from sources on my Debian box. At last I had success.

This should be an easy to follow guide about how to install Xen on Debian 5. You should be able to copy/paste most parts of on your shell. Please run this only on a clean and up-to-date Debian system.

Currently there is no package for the Haskell-Platform in Debian stable. However, the source of this platform and GHC is available for download at ghc and platform.

Yesterday I played with QEMU in order to run a Debian Lenny distro on a virtualized ARM arch. The Debian installation was easy thanks to this post of Chris Dew. I just wanted to point out what I did to get the virtual machine running after installing the distro.

Debian Etch is soon to be unsupported by the Debian team, there for all Debian Linux Servers need to be upgraded to Debian Lenny, I work for Netzen (an IT Support company) and have upgraded many Linux servers to Debian Lenny over the past month, So I am providing this guide on how to upgrade [...]

When Debian issues a point release, as it just did with the current Stable distribution Lenny going from the 5.0.3 to 5.0.4, it’s no big deal. They happen. But you don’t need to throw out your Lenny install CDs or do any kind of reinstallation.

During much of the time I was running Ubuntu, I told myself that I’d be running Debian instead, if only I could get everything working.

The Debian project is pleased to announce the fourth update of its stable distribution Debian GNU/Linux 5.0 (codename “lenny”). This update mainly adds corrections for security problems to the stable release, along with a few adjustments for serious problems.

mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM’s snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again.

Finch is a powerful text user interface instant messaging client based on libpurple, and it comes included in the Pidgin source, the popular GNOME IM client.

This short tutorial describes how to configure JBoss Application Server (Jboss GA 5.1.0) on a debian linux (Debian GNU/Linux 5.x “Lenny” ).

module-assistant is a tool for building Debian kernel modules from source, without having to rebuild the whole kernel. It fetches module-source packages that have been prepared for the Debian distribution via apt and produces .deb packages.

This tutorial will show how to compile and install the latest VLC from source in Debian Lenny in several steps. The current version at the time of writing is VLC 1.0.1, so the tutorial should work successfully for it.

After compiling MPlayer on Debian 3.1 Sarge, I looked for a decent frontend to MPlayer. I found two frontends, SMplayer and Gnome-Mplayer. I chose to try Gnome-MPlayer because I am a GNOME person

After having a bit of a nightmare getting any kind of live-system to boot on any mac in my flat (usb, cd etc), I realised that little sluggy which my brand new PC Engines board is due to, well not replace (particularly in my heart), but help out a little bit, was still faithfully sitting [...]

FreeSWITCH is an open-source telephony platform designed to facilitate the creation of voice and chat driven products scaling from a soft-phone up to a soft-switch.

This is for some who face difficulty in reading NTFS partitions in Debian.

The NTP service that uses network-time servers to keep your computer’s clock from drifting is another thing that Ubuntu includes by default but must be added to Debian if you want to use it.

Because we have several servers that was upgrade from Debian Etch and the to Debian Lenny via the “apt-get dist-upgrade” path , I need to upgrade older instance postgresql 8.1 to postgresql 8.3 as smoothly as possible.

I want to use the Ext4 filesystem on Xen DomUs. The reason for this is that the problem of fsck times on ext4 (as described in my previous post about Ext4 [1]) is compounded if you have multiple DomUs running fsck at the same time.

This post shows you how to install the Adobe Flash Player, formerly known as the Macromedia Flash Player, on Debian systems

Sure, Debian Stable is boring. There’s no fanfare every six months about the next release (and if I wanted newer everything, I could upgrade to Testing, currently Debian Squeeze).

OK, let’s just get right to it. We both know why you’re here and you’re probably raring to get JACK and some client apps running in RT mode with low latencies as quickly as possible.

This brief tuto­r­ial is about installing a per­fect server with the new Debian 5.0 (code­named Lenny) Linux Oper­at­ing Sys­tem. At a later date, we will test drive some of the added fea­tures and how it can be used as a solid busi­ness solu­tion to run crit­i­cal busi­ness applications.

The reason I am writing this post is because I tried many howto’s which didn’t work and I eventually ended up combining some to get both rtorrent and wtorrent to install and run on my Debian 5 Lenny VPN (thanks to Costin for the VPN).
