I’ve ordered my first Moo cards today! I chose to upload my own photos and I used 8 photos from my world tour. I hope they turn out good, although I’m sure that they will – here are the photos I used:

I did some work recently for a client at work who were having issues with their Trixbox system. This involved going on site and deciphering the problem with their network and figuring out exactly what was going wrong. It turned out that all the problems were related to a Trixbox misconfiguration in the sip_nat.conf file where localnet was set to 127.0.0.1/255.255.255.0 and thus Trixbox was trying to do NAT when talking to any phone. This was putting extreme strain on the ADSL router at the edge of the network and causing no end of problems.

It’s unsure where the misconfiguration came in, but all has been resolved now. The client has blogged about it and it has even gained some press from ZDNet.

Anyway, the way we solved the problem was by testing the network from a baseline which we knew *must* work. This led us to trap the problem between the Trixbox server and the ADSL router, which in this setup, shouldn’t have needed to talk to each other. That led us to check the NAT setup which is how we found the problem. I planned the work we carried out the day before and it just goes to show that prior planning leads to a successful days work.
