Kerry Garrison - Building your own PBX
Building Your Own PBX with Asterisk
Kerry Garrison
What would it mean to you to have your own full-featured PBX system at your home or small office? What would it mean to you if you could build an entire PBX system (minus the phones) on hardware you probably have laying around, AND that it can probably also save you money on your phone bill? Sounds too hard to believe doesn’t it, but using old hardware and some open source software, you really can build a commercial quality phone system that would normally cost thousands of dollars.

The Hardware
As I mentioned in the opening, we are going to build our PBX system from equipment that we have laying around the house. After cannibalizing three spare systems, what was left was a PII 450, 386mb RAM, 12gb HD, 48x CDROM drive, and an Intel Pro 10/100 network card. This is all you “need” to get going as long as you are going to get VOIP dial tone service from a company like BroadVoice (more on this later). If you want to use regular analog phone lines you will need modem card. Not every card will work properly, however, the most recommended card is the Digium Wildcard X100P FXO card which can be purchased brand new on eBay for $6.95 each. So far, total out of pocket expense for the card plus shipping: $12.90.

BURLINGAME, Calif. — The key to the speed and reliability of Google (Quote, Chart) search is cutting up data into chunks, its top engineer said.

Urs Hoelzle, Google vice president of operations and vice president of engineering, offered a rare behind-the-scenes tour of Google’s architecture on Wednesday. Hoelzle spoke here at EclipseCon 2005, a conference on the open source, extensible platform for software tools.

Here is an article on Filesystem integrety checkers. There are several filesystem integrity checker applications, both commercial and open source. I chose to deploy afick, because it is written in Perl, which makes it lightweight and easily portable between different operating systems. Though by nature designed for the command line, afick also has an optional Webmin module and a graphical interface written in perl-Tk.

RTG: Real Traffic Grabber
RTG is a flexible, scalable, high-performance SNMP statistics monitoring system. It is designed for enterprises and service providers who need to collect time-series SNMP data from a large number of targets quickly. All collected data is inserted into a relational database that provides a common interface for applications to generate complex queries and reports. RTG includes utilities that generate configuration and target files, traffic reports, 95th percentile reports and graphical data plots. These utilities may be used to produce a web-based interface to the data.

First off I always recommend a complete format for any machine that has been infected with any virus, worm or trojan. Basically if your computer has been compromised then treat it as so and start over to be safe. That being said you probably want your data off your computer prior to formating it. Now don’t just go copying data off the infected windows computer to another windows computer. You are likely to just spread the infection. So here is an excellent article on how to clean the data using Knoppix prior to moving it to another computer.

Making the Jump to Subversion


11 Aug 2004: “If you haven’t checked out Subversion, you should. It’s a free, open source, powerful revision control system that was built to be a better CVS. It was created with clear design goals and built on top of robust, time-tested technologies. If you’ve been waiting for a better CVS and are ready to roll up your sleeves, skip directly to the Installing Subversion section of this article. However, instead, you may be saying, “But c’mon, I’m a busy programmer, this sounds like extra work to me.
