cfengine – practical examples

In a sea of inadequete cfengine examples, one stands out: http://www.sysadmin.hep.ac.uk/wiki/Cfengine. I’m in the early stages of developing an administration strategy for a jail server I’m setting up. It will run regression tests for Bacula. I’ve already found ezjail, which will help me create the jails. What I needed was tool for administering the jails. I don’t want to ssh to 10 different systems just to update a script on each one. I

OSCON 2007 – the details, the people

I was at OSCON 2007 this week. I was there to present my Nobody Ever Regretted Making a Backup talk: In the past few years, Bacula has been gaining ground on more established solutions, both open source and proprietary. This talk will introduce you to Bacula, show you the main components, give you an outline of how it works, and illustrate why Bacula is becoming so widespread. My talk was scheduled for the

Good bye IPsec. Hello OpenVPN.

I’ve been playing with OpenVPN since mid December. I like it. I like it better than IPsec. Why? Because OpenVPN can give me direct access to all my systems wherever I am. I can cvsup from my cvsup server at home from a hotel in Toledo (if I’m ever there). IPsec can do that. But it is much more complex to set up. OpenVPN is pretty simple. At present, my wireless gateway is

Bacula – restoring to Windows

Today, as I was writing up an invoice, I accidentally saved it over another. No worries!  Bacula to the rescue.  I managed to get the original files back from tape. One hint: include your pathnames in “quotes” so they are correctly parsed.  Like this: $ dir ———- 0 root wheel 0 1969-12-31 19:00:00 c:/ $ cd “c:/Documents and Settings/Dan Langille/My Documents/Technologies” cwd is: c:/Documents and Settings/Dan Langille/My Documents/Technologies/ $ dir -rwxrwxrwx 1 root wheel 63655 2006-10-05 14:32:49 c:/Documents and Settings/Dan Langille/My

Burst and Google make a good team

Just about everyone has been putting ads on their websites. I’ve been with BurstMedia since early 1999. They are very reliable. Their cheques have always arrived on time and I have never had reason to question their results. Then Google AdSense arrived. I started using AdSense in April 2006. I was still using Burst, but added AdSense as a personal campaign. That is, if Burst could not fill a particular ad slot, AdSense
