Mercurial: GPG Sign Tags
Oct 5th
I recently needed to write a pretxnchangegroup hook that would check if any new tags had been pushed, and if so, if they were GPG signed. I had the requirement that the changeset with the tag be signed, not the changeset that added the tag. I’m not a python coder, so I opted to go for a simple bash script to accomplish the task. The only option the script has is whether or not the hook can fail if a changeset does not have a valid signature. If the option is disabled, it will only throw an error, but the hook will still pass. More >
L2TP/IPSec in Ubuntu 10.04 et al.
Apr 1st
I’ve spent the last week looking through the web at everything I could possibly find in an effort to find some shred of information that made some sort of sense and didn’t take a rocket scientist to configure. I found plenty of instructions on manually installing Openswan, xl2tp and modifying their configuration files and entering a pre-shared key here, or putting a certificate there, blah, blah blah, blah blah. After many failed attempts, I was pretty much ready to give up. More >

DDoS-Deflate Revisited
Feb 18th
I recently had the task at work of setting up a simple DoS protection for our public web server. After poking around some bit, I settled on using DDoS-Deflate. We use Ubuntu 10.04 on our server and unfortunately, the script seems to have been last updated over 5 years ago and I needed some modifications to make it work in our environment. I also didn’t like the idea of the install script needing to download files from some web server and have packaged it up all in one (linked at the end of this post).
