One of the challenges with running my own server now, is making sure everything is properly patched. With the big stink around the new Heartbleed vulnerability, it made me look into it a bit.
Turns out, in order to fix you can run the following:
sudo apt-get update sudo apt-get install -y libssl1.0.0 openssl # Confirm Build Date is at least Aril 7th 2014 openssl version -a # Restart all services listed by this command: sudo lsof -n | grep ssl | grep DEL
With the move of my domains to Azure instead of Dreamhost (oh, did I not mention that?), one of the things I needed to do was setup some SPF records to keep email from going into junk folders.
Now, there is a great article on creating SPF records, but those that know me know I’m not a big reader when there is a lot of text. Pictures FTW!
Anyways, as MS is a big proponent of utilizing SPF, they have created an excellent tool to create the record’s text. Yay team!
I’ve finally migrated my email from google apps to outlook.com. The key item that caused some issues was using domains.live.com. I had added the MX record that proved I owned it (and email was flowing correctly).
However, it was always set to “pending” and never switched to “active”. The problem is that the Hotmail.com MX record is the only MX record you can have. I had some of the old gmail records listed still, but at a much lower priority (higher number). Removing them immediately made it switch to active.
Grr.
In the last few releases, Synology has added L2TP/IPSec as an option for a VPN. I’ve never been able to get it to work on a Windows client until today.

I finally got around to installing Windows 8.1 Public Preview. I am definitely liking the new digs. However, I already started to look into how to uninstall due to the following items that I’ve now gotten sorted out (hopefully helps someone else):
Oh well, with the bad comes the good:
Overall, seems to be good now that I’ve surpassed the biggest hurdle.
I have an app that can call a single script, sending it some variables. Unfortunately, I needed to run multiple scripts, but both utilizing the same variables. With bash, there is an easy way to do that, just append “$@” to the script.
For example, the application calls ‘combined_scripts.sh’ with variables $1 through $7. The contents of ‘combined_scripts.sh’ is below and the variables are passed through to script1 and script2.
#!/bin/sh ./script1.sh "$@" python ./script2.py "$@"
I’ve been fighting this for awhile as the mkvtoolnix package doesn’t have the correct dependencies when you install it. Well, after doing a bit more digging I’ve found the answer to get mkvmerge to work!
Packages required:
Then, you need to set an environment variable of LANG=C. This can be done from the command line.
Tada, works!

*UPDATE – Jan 1 2016*
In addition to the LANG=C environment variable being set, I’ve also had to add in LC_ALL=C. For me, I run a script that calls mkvmerge, so I just set both of these in the script.
Well, after starting to put together my own quadcopter, Adam decided he wanted to get on the bandwagon too. However, he went down the kit route, where I’m still waiting for all my parts to arrive (not the ones listed in a previous post).
Well, after some initial indoor trials, he took it outside for some flying. It was a bit windy, and we were only using the small battery packs we had (1300mAh), but it was crazy fun. The GPS lock on his is nuts. I wish I was filming when the wind picked up and the quad banked into it…under its own brain power.
These things are crazy fun, and driving one is just like a first person shooter. I was pretty worried about how the controls would be, but after flying his, I’m not worried at all. Now I just wait for the servo wires and frame to get here, and I’m off to flying too!
