Using MySQL to benchmark OS performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3460 Comments
Tutorial quote: It seems to be an exciting time for *nix operating systems, with a number of them recently releasing new versions that bring the addition of expanded features and claims of improved performance. If you're using GNU/Linux, OpenBSD, NetBSD, FreeBSD, or Solaris as a database server, you've probably recently considered an upgrade or switch to another OS in that list due to marketing hype and hearsay. This article will show you how to benchmark operating system performance using MySQL on these OSes so you can find out for yourself if you're missing out. While this may not necessarily be indicative of overall system performance or overall database application performance, it will tell you specifically how well MySQL performs on your platform.

The following operating systems were used for the comparison testing:
- FreeBSD 4.11
- FreeBSD 5.3
- NetBSD 2.0
- Linux 2.6
- Linux 2.4
- Solaris 10 x86 (build 69)
- OpenBSD 3.6

Linux stateful firewall design

Post date: April 12, 2005, 17:04 Category: Network Views: 2387 Comments
Tutorial quote: This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.

Running ISPConfig On Port 80 Using Apache's Reverse Proxy Feature (Debian Etch)

Post date: May 23, 2007, 22:05 Category: System Views: 4531 Comments
Tutorial quote: This article shows how you can configure a Debian Etch system that has the webhosting control panel ISPConfig installed so that ISPConfig can be accessed on port 80. By default ISPConfig uses port 81 which is a non-standard port and is blocked by some firewalls and ISPs. By using Apache's mod_proxy module, we can avoid this problem. It lets us create a reverse proxy that can fetch the pages from ISPConfig on port 81.
