Building a DUL on demand

Wednesday, July 16th, 2008

A DUL or a Dial-Up-List is a DNS list that gives an A record (usually in the 127.0.0.0/24 range) for IPs that’s dynamically assigned, such as dial-up users, or various DSL services. Basically, any technology where an IP is not assigned to a specific person (3G, iBurst, ADSL, sentech, dial-ups).

Ultimate Linux Solutions blog

Friday, July 11th, 2008

Under the influence of Quintin van Rooyen (blog.g33q.co.za) I decided it’s time to get this set up. So here it is, the official Ultimate Linux Solutions blog. Hopefully I’ll be finding time to write a little about what we’re up to, the challenges we’re working on and hopefully some of the cool things we manage to achieve.

For now though, it’s a Friday evening, and I believe it’s time to grab a bit of rest for the weekend, although, I’m pretty sure some Voice-over-IP experimentation will manage to sneak in at some point tomorrow.
