Post date: November 27, 2006, 02:11 Category: Network Views: 7440 Comments
Tutorial quote: The tutorial is about firewalls and related functions, with examples from real life with the OpenBSD project's PF (Packet Filter). PF offers firewalling, NAT, traffic control and bandwidth management in a single, flexible and sysadmin friendly system. Targeted at the seasoned or aspiring network administrator, this half day tutorial manuscript will give you some ideas about how to control your network traffic the way you want - keeping some things outside your network, directing traffic to specified hosts or services, and of course, giving spammers a hard time.

You may ask yourself: "But I can use vmbuilder to do this, why do I need virt-install?" The difference between virt-install and vmbuilder is that vmbuilder is for creating Ubuntu-based guests, whereas virt-install lets you install all kinds of operating systems (e.g. Linux, Windows, Solaris, FreeBSD, OpenBSD) and distributions in a guest, just like virt-manager.

Using MySQL to benchmark OS performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3507 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

OpenOffice 2.0: Creating database forms

Post date: December 13, 2005, 12:12 Category: Software Views: 2898 Comments
Tutorial quote: ather than having a shallow affair with OpenOffice 2.0, we can use it to get a little more intimate with the data. We can even badger it into forming relations. Why force your database tables into a marriage with OpenOffice? Because, as with human relations, life -- and data -- are pretty meaningless without tight connections.

This tip on creating forms is part of a series I'm writing on OpenOffice.org 2.0 Base. So far, I've discussed making a plain database from scratch, creating tables, entering data using the table editor and a simple form and creating a view of a table or tables.

Let's start off with a description of what table relations are anyway, then discuss how to create a data entry form like this one, which has data from two related tables.
