Today is August 2nd, 2011 or 8/02/11. Written another way… 802.11 which you might recognize as the wireless standard, e.g. 802.11a/b/g/n. As someone who uses wireless at home, work, and while traveling, I am happy to offer a day of celebration to the wireless standard which has been so helpful to me, both personally and [...]

Weekend Server Overhaul
In early 2010 I signed up and migrated to Linode.com for my server needs. At that point in time, the latest version of Ubuntu that was offered was 9.10; the only useful colo location was Dallas; and IPv6 was unheard of (well, not exactly unheard of, but having a server with IPv6 was). We’ve had [...]
Goodbye AT&T, Hello Sonic.net
The alternate title for this post is “Internet usage caps can kiss my ass” because that’s what prompted this post, but first a little backstory. Many people have had issues with big teleco (and specifically AT&T) provided internet and would assume that I loathe them for the same reasons, but I do not. I’ve had [...]
Setting up PowerDNS Server with PowerDNS Recursor
I needed an open source DNS solution at work recently, preferably anything but Bind, and it was suggested I use PowerDNS. I had no experience with it, but I was told it was a good product and fairly easy to setup. On top of the DNS Server itself, I need a local DNS caching agent. [...]
Samba and LDAP DO NOT MIX
Recently I was tasked with helping a company implement a centralized authentication system, and they wanted to go all open source. This isn’t unreasonable in my book, though it is a little unusual. Of course the words “Open Source Authentication” directly translates to LDAP, the only question is which LDAP software you’re going to use. [...]
Erase the configuration on Cisco 2600/3600 Routers
A bit back I decided that I should investigate following the Cisco Certification path. The lower levels aren’t hard, but all things considered, you really need to have a “test lab” of equipment to play with. So a few weeks ago I was offered a pair of old Cisco 2600 series routers on the cheap, [...]
Dial-Peers on Cisco 3600
When I setup the Cisco 3600 in the office to work with asterisk as our FXO ports, I needed incoming and outgoing capabilities. In was easy enough, but out was more tricky because you need to setup specific dial-peer plans. Well for the longest time I had 3 different sets of rules per port (911, [...]
When working with Cisco
If your making changes you want latter – Suggestion: Always write the configuration to memory. We haven’t been using our old voip router recently (newer gear for cooler stuff), so I was playing with it a while back (you may remember FXSs are a go! ) – Except I forgot to save my changes to [...]
FXS’s are a go!
Well its amazingly difficult to find documentation about how to make FXS’s work with Asterisk. I happen to have 4 FXS ports on the Cisco 3640, the same one that has four FXO ports. Below I’m including my configuration for use by others. The FXS port is configured as extension 600 (the Asterisk side configuration [...]
Yea for PBX’s
So several months ago I moved our small office over from a Windows 2000 box running some Microsoft built-in IP telephony software, to an Asterisk PBX. Now I’ll admit I knew almost nothing about Asterisk, or Cisco hardware. Since then I’ve made major strides. Yesterdays project was to see if I could get a Cisco [...]
