Watching Hard Drive Activity With iotop On Ubuntu 8.10 And Debian Lenny

Watching Hard Drive Activity With iotop On Ubuntu 8.10 And Debian Lenny

This article shows how you can watch your hard drive activity with iotop on Ubuntu 8.10 and Debian Lenny. iotop watches I/O usage information output by the Linux kernel and displays a table of current I/O usage by processes or threads on the system. iotop displays columns for the I/O bandwidth read and written by each process/thread during the sampling period. It also displays the percentage of time the thread/process spent while swapping in and while waiting on I/O. In addition the total I/O bandwidth read and written during the sampling period is displayed at the top of the interface.

The Perfect Desktop - Debian Lenny

The Perfect Desktop - Debian Lenny

This tutorial shows how you can set up a Debian Lenny desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

Desktop Search In Ubuntu Intrepid (And Debian) In KDE 4.2

Desktop Search In Ubuntu Intrepid (And Debian) In KDE 4.2

Ubuntu Intrepid 8.10 features an inbuilt desktop search. Unfortunately I never managed to get it to work right and I tried a lot of things. So I finally went on irc.freenode.org into the #strigi channel and asked for help. Lucky me Phreedom in there gave me a helping hand. Why Nepomuk doesn't work by default is still a mystery. I think this is related to Redland instead of Soprano. Unfortunately, as Phreedom told me, the Ubuntu and Debian maintainers don't supply Soprano with the current builds. Also his recommendation is to use KDE 4.2 (Kubuntu 8.10 comes with KDE 4.1).

The Perfect Server - Debian Lenny (Debian 5.0) [ISPConfig 2]

The Perfect Server - Debian Lenny (Debian 5.0) [ISPConfig 2]

This tutorial shows how to set up a Debian Lenny (Debian 5.0) server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. In the end you should have a system that works reliably, and if you like you can install the free webhosting control panel ISPConfig 2 (i.e., ISPConfig runs on it out of the box).

Virtualization With Xen 3.3.1 On Debian Etch

Virtualization With Xen 3.3.1 On Debian Etch

This tutorial provides step-by-step instructions on how to install Xen on a Debian Etch (4.0) system. Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

How To Set Up Apache2 With mod_fcgid And PHP5 On Debian Etch

How To Set Up Apache2 With mod_fcgid And PHP5 On Debian Etch

This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on Debian Etch. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.

Caching With Apache's mod_cache On Debian Etch

Caching With Apache's mod_cache On Debian Etch

This article explains how you can cache your web site contents with Apache's mod_cache on Debian Etch. If you have a high-traffic dynamic web site that generates lots of database queries on each request, you can decrease the server load dramatically by caching your content for a few minutes or more (that depends on how often you update your content).
