I could not find any way to see how you could add an IP address as a ‘white list’ for our Postini installation. Mails coming from our mailing list manager kept getting caught in the Postini spam interface (which is probably a whole other issue, which I will need to address later). To get Postini to white list an IP address, you need to go into the Batch editing mode and issue this command: addallowedip organization name,domain.com:10.0.0.0 Full Postini Batch Reference See page 30 for ‘addallowedip’ syntax and more information.

As previously written on this blog, I have set up a display in our lobby at work to display the day’s current events and meetings using Ubuntu and a tiny PC. Since this is a display which is on all day, the screensaver and monitor blanking (and other Energy Star features) are all turned off. Under the auspice of wanting to save energy and also extending the life of a new monitor, someone suggested that we turn off the monitor at night using an electrical timer. A lightbulb went off in my head, that there must be a better way to do this via command line and then run it in the cron. It turns out the solution is very simple. The xset command is the X server preferences command. It has a simple command to turn off the monitor: 1$ xset dpms force off and to turn the monitor….
