I’m an awful sysadmin. Running services permanently isn’t really my forte, I tend to lean more on the “I’ll get this proof of concept all working, prove that it works or doesn’t, then roll it on for polishing by someone else” kinda guy. That final 15% is something I’m constantly working to refine and better myself at accomplishing. I’m decent at debugging network services, and can be handy in a “oh crap, it’s down!” scamerio,…

I’ve been looking at iMessage from time to time as my schedule permits, for some reason that I can’t really explain I’m fixated on it. So, just like I did with FaceTime, I started doing network sniffing to see just what it’s doing. The results were not terribly unexpected.
I have recently enabled Duo Security for many of my personal services, and I can’t recommend them enough. Personal two factor authentication is very useful and really powerful. It works on my iPhone and I have yet to run into any real issues….except for one. I can’t use automation to scp or sftp anything anymore and keep my two factor auth working in a way I’m comfortable with.
It’s no secret or ground breaking area to do black hole routing.
Google has introduced a very powerful set of python based command line (CLI) tools called GoogleCL. This post was made using GoogleCL from my Mac. I highly recommend checking it out if you like to automate or script stuff.
I’ve recently decided that even though I love the BSD style MacPorts system, it can be too clunky to maintain and doesn’t handle dependancies as well as I’d like (much like the actual BSD ports collection). So, in doing a little looking I found that Fink is still out of date, but Homebrew is very simple and also really elegant comparatively speaking.
I’m not a fan of IPv6 privacy addressing. I understand the logic behind it, I really doo, obfuscate the LLADDR (MAC address) of the host in question, but I really dont’t see the realistic purpose. If someone wanted to use my mac address, what good would that really get them, unless they’re on the same layer 2 segment? More importantly, if they;re on the same layer 2 segment, they have my MAC address anyway.
Privacy addresses cause more heartburn than they cure. How do I track…
It looks like MacOS 10.7 (Lion) has fully functioning DHCPv6. It’s about time.
I did some minor tweaking to the Alcatel Lucent RANCID scripts and some modifications to make RANCID work under my pfsense environment (originally m0n0rancid code from John Skopis). Since I don’t really do much dev work and am not interested in maintaing a box do be an SVN server for the public, I threw it up onto google code.
I’ll be adding a brief how-to on making RANCID work with pfSense as soon as I get some time.
I’ve been a *BSD user since around 1997, when I installed NetBSD on a Mac SE 30 that I got for free. I was always intrigued with alternative operating systems like BeOS, *BSD, Plan9 and Linux so it made sense that I’d poke around with different systems.
