Modern Linux distributions use udev which automount partitions to the system. This is most notably seen with usb device that are the predominant hot swappable media. Internal hard drives, particularly drives that are used to boot the system, have their mount points defined in the fstab file. Fstab is automatically generated during the Debian/Ubuntu installation [...]

If you run out of space on a particular partition, but you have excess space on another partition you can relocate your data. Lets say you have 100 Megabytes left on /dev/hda1 but your have 10 gigs left on /dev/hda2. Lets say you have a folder on /dev/hda1 /home/user/backup that is over 2 gigs. Lets [...]

Mod security has features that go above and beyond a standard firewall. It will help to prevent denial of service attacks, and also can be used to block traffic based on realtime blackhole lists issued by Spamhaus and others. Mod security is apparently in the Debian repositories as well as Ubuntu. In the Ubuntu repos [...]

Server side includes allow for external html documents to be injected into a page prior to it rendering on the client web browser. The benifit of this is eliminating the need to repetitiously repeat code over and over again. If you include the same scripts, on each of your website pages, you can create an [...]

Apache2 implements a structured method of organizing and enabling/disabling modules and sites. The default apache2 host is automatically turned on in /etc/apache2/sites-enabled/, and it includes the virtual hosting option. Therefore, by default, virtual hosting is enabled. Create your virtual host containers in /etc/apache2/sites-available, and then enable them by issuing the command:
sudo a2ensite xxxxx.com
VirtualHost containers are [...]

I’m using LTSP to manage a server remotely in a local facility. I setup an LTSP server on the host machine, and will place it in an air-conditioned room to preserve longevity. I configured a machine, of much lower power, to PXE boot from the server. There are several nuances to setting up an LTSP [...]

You should have backups of all your files all the time. For a desktop machine always have a backup of your entire /home partition. Use a cronjob and rsync. Mount a usb drive to the /media directory. Use a cronjob as follows:
1 1 0 0 0 rsync -r /home/user /media/backup/user
The above rsync will recursively transfer [...]

The first thing to do it get lighttpd installed with php and mysql working smoothly. Rather than reiterating the same content here is a convenient post:

Interesting options and various configuration for lighttpd can be found here:

One insteresting, built in, option is throttling. Use connection.kbytes-per-second and you can effectivly limit users to particular data transmission rates. [...]
