I have been sitting on a half post for a while now on setting up Asterisk on EC2 and then this past week someone else came out with a post on how to install Asterisk from scratch on EC2. I figured I would wrap up what I have since I take the path of installing Asterisk on VirtualBox first then converting that disk image to an AMI as I outlined a few weeks ago when I got serious about testing out the Asterisk on EC2 concept.
Reading over the comments on the Voxilla post you will see some concern about how cost effective putting Asterisk on EC2 would be. Even if the cost is an issue for normal use I think Asterisk on EC2 could work for bursts of outgoing calls or even temporary conferencing systems. Part of what I wanted to do was find the least resistant path to getting started so I went with Trixbox since it has a lot of tools pre-installed and support for Gizmo5 that was very easy to set up. The key with Gizmo5 is that it is cheap, works with Asterisk via SIP and you can have incoming calls for free from a land line so it is easy to test cheaply.

I've been using S3 to store semi-transient information like log files from EC2 nodes in the past but recently decided to give Amazon's Elastic Block Store (EBS) a try instead. I quickly realized a downside to using EBS in that there is no mechanism for auto-attach and mounting volumes when an AMI is launched. This is probably something Amazon will fix at some point and allow you to launch a given AMI with an attached EBS volume but until then you need some way of doing it yourself. The following is a simple way of using ruby to make it happen.

Fedora 10 is out and once again it is time to upgrade. The upgrade from Fedora 9 to Fedora 10 is almost exactly like the upgrade from Fedora 8 to Fedora 9. Here are the steps you need to do the upgrade from Fedora 9 to Fedora 10.

I recently needed to find a RADIUS server for use in a project where I could stick profile data into Oracle. I remembered seeing FreeRADIUS a while back so I checked to see if it was active and supported Oracle. Sure enough it did. It was a little tricky to set up because some of the documentation is out of sync with the latest version so here is what you need to know to get it working.

I recently got a new work PC and was worried that stuck somewhere in the 40G hard drive of the old PC was something I would one day need. The new PC had 300G of space so I figured I would just copy the entire drive over and keep it forever. This isn't the most difficult task in the world and I actually started out using ssh to transfer the image.
