Simple Linux DHCP / DNS Server

I’ve just completed the first DNS and DHCP server that I’ve built for a while. This was using Ubuntu Linux 8.04.

The nice thing about the process this time around as opposed to when I set one up a couple of years ago is that I was a little more au fait with the process. The DHCP successfully updated the DNS records, and everything ticked along nicely.

It’s going into production tomorrow, so I’m hopeful that it will fix a number of network problems that a client has been having with the RM DHCP Server service that runs in Windows XP.

If it would be easy to tie the upcoming Samba 4 into the mix, then I think that you have the perfect open source server! I have another server to put together soon, so I plan to write a ‘howto’ and post it here.

BlackBerry Update

Well, the BlackBerry is coming along nicely. I’m gradually getting it to work the way I want it to work.

So far, the cool bits are:

  • Google Maps uses either GPRS or GPS (you can connect a GPS receiver with Bluetooth)
  • Yahoo! Messenger works off the bat and can stay connected at all times. Never miss an IM again.
  • Google Sync syncs up with phone with my online calendar – finally a computer-less way to do this!
  • Impressive battery life. Even though I have been caning the phone with online and Bluetooth as well as loads of phone calls – it breezes through the day without any problems.
  • The Pearl is noticeably smaller than the N80 and the Razr. This goes against my reputation of having a brick-like phone.

There are some other neat things as well. I had some trouble transferring contact data from my N80 to the BlackBerry, but after some experimentation I found a way to do it that didn’t require a computer. It was somewhat tedious having over 100 contacts though.

I still want to get an IM program installed that will use MSN, as some of my business contacts use this. This will tie in with Yahoo! and Google Talk nicely and round it all off.

The built-in browser is a bit useless, so I’ve installed Opera Mini which can render pages properly when the browser gets stuck. I often find myself flitting between the two though, as Opera doesn’t seem to handle downloads properly.

The only downer is that the BB Pearl doesn’t seem to connect to Ubuntu properly through USB – and the Bluetooth connection is a real pain in the arse. This is probably going to make any kind of synchronisation very difficult – to nigh on impossible. There are the Linux Barry tools in development, which have some way of backing up data and things – but I haven’t had the chance to have a play with these yet.

All in all – the experience is going well, and I’m hoping that I can import my MSN contacts into Google Talk soon. Unfortunately to do that, I need to update our company domain SRV records which is opening another can of worms…
