Linux virtual server on Debian Sarge

Post date: November 29, 2005, 21:11 Category: System Views: 4002 Comments
Tutorial quote: Linux-VServer allows you to create virtual private servers and security contexts which operate like a normal Linux server, but allow many independent servers to be run simultaneously in one box at full speed. All services, such as ssh, mail, Web, and databases, can be started on such a VPS, without modification, just like on any real server. Each virtual server has its own user account database and root password and doesn't interfere with other virtual servers.

Upgrading FreeBSD

Post date: April 1, 2006, 05:04 Category: System Views: 4348 Comments
Tutorial quote: This document started as a follow up to The Ultimate Multimedia Server Guide and how to go about keeping your server up to date and patched with the latest O/S patches and security patches. The other reason for this document was to try and create an easy to follow update guide for the not so Unix savvy users that visit my website from time to time. My first time trying to upgrade FreeBSD from sources went well but trying to understand and piece together all the other documentation was more of a daunting task than actually upgrading.

Delete Qmail Server messages Queue

Post date: January 12, 2007, 18:01 Category: Software Views: 3395 Comments
Tutorial quote: qmail is a mail transfer agent that runs on Unix. It was more secure replacement for the popular Sendmail program. The author offered a $500 prize for the first person to publish a verifiable security hole in the latest version of the software.

This is a useful thing to do in a number of situations. For instance, if you are hit with a spamming attack, you can temporarily instate a second Qmail installation (once the spam run is finished), allow it to take over mail receipt,and then use this tool to clean the offending mails out of the queue before switching over to the main Qmail installation once again.
