Birdy – Skinny Love (Vanic Remix)

Time to turn up your speakers! This is a great remix. It’s a 5-minute crescendo that doesn’t stop oozing awesomesauce. Just when you think it’s starting to drip, Vanic turns back on the tap. Birdy has a great vocal, and the bassline build coupled with the unexpected (but oh, so welcome) dubstep breakdown makes it impossible for me to turn off the repeat feature.

For those interested in a little history lesson, here’s the original version of the song.

Why support may ask for your backup.nems file, and why you should never share it with others

During support sessions I often request either SSH access or a copy of the user’s backup.nems file. SSH access, it should be obvious, should not be shared with just anyone. Also, you should never, ever, ever, open SSH to the world on your NEMS server if you have not yet initialized it. This is because there are botnets that look for Raspberry Pi computers which use the default “raspberry” password, and then compromize them. Continue reading

Setting up NRPE on Windows for NEMS

Please Note: As of NEMS 1.2 NSClient++ is optional for monitoring of Windows computers (thanks to the addition of WMIC). If you’d like to use it, please follow the directions below.

  1. Grab the latest Windows client at https://www.nsclient.org/download/
  2. Install the client with the following settings:
    • Select to install the “Generic mode” NSClient++.
    • Choose “Complete installation” and if asked, choose to save config to ini file.
    • Under “Allowed Hosts” it should read 127.0.0.1,NEMSIP (where NEMSIP is the IP address of your NEMS server)
    • Clear the Password field for ease of deployment. NEMS sample scripts are setup to use NRPE without a password because I’m making the assumption that this is being deployed in a trusted LAN. If you do not blank the password here, you will have to edit all the scripts before NEMS will be able to communicate with this computer.
    • Enable all modules and change the NRPE mode to Legacy. NEMS uses Nagios 3.5.1 at present, and I suppose that’s technically “Legacy”. 🙂
    • Screen should look a little something like this:
      nsclient-setup
  3. Add your Windows host to NEMS. If you are using NEMS 1.1+ you can use the template “ourwinserver” in nconf. Just change the hostname and the IP address.

Please note: If you have a software firewall running on your Windows machine, setup an exception for your NEMS server IP to gain access through ports 5666 and 12489.

Backup a Linux machine with LVM Snapshots and rdiff-backup

Here is the completed script I wrote on Episode 461. Make sure you check out the full episode for details on how to make this work for you.

#!/bin/sh
/sbin/lvcreate -L10G -s -n lvm_snapshot /dev/ubuntu-mate-vg/root
/bin/mount /dev/ubuntu-mate-vg/lvm_snapshot /mnt/snapshot

/usr/bin/rdiff-backup -v5 --print-statistics \
  --exclude /mnt/backup/ \
  --include /mnt/snapshot/home/ \
  --include /mnt/snapshot/etc/fstab \
  --include /mnt/snapshot/var/log/ \
  --exclude '**' \
  / \
  /mnt/backup/

/bin/umount /mnt/snapshot
/sbin/lvremove -f /dev/ubuntu-mate-vg/lvm_snapshot

And of course, here is the episode:

Drone Zone Skill Rating

With The Drone Zone about to take flight, I wanted a way to rate the skill level required (or rather, recommended) for each drone we review. The purpose is so viewers can gauge during a review, from the DZSR (Drone Zone Skill Rating) which drone(s) they should be looking at first.

I’m open to suggestions, so please post your comments and this will become a bit of a living list, updated as needed. I will also maintain a static copy on The Drone Zone web site.


DZSR Level A
This drone is perfect for a beginner pilot. It’s easy to learn, has a price point that won’t hurt your wallet too badly if you crash it, and is a good drone to start with. As you take on drone flight, it’s best to start at DZSR Level A so you can learn the controls, practice, and get ready for the next level.
Mature pilots will also enjoy drones in this level as they’re nice to be able to carry around so you can fly wherever you are just for fun, without much consideration, packing or planning.
Typical drones in this level: Nano quads.

DZSR Level B
If you’ve mastered drones at DZSR Level A, you’re ready to move on to DZSR Level B.
Typical drones in this level: Toy camera quads, Entry level FPV.

DZSR Level C
If you’ve mastered drones at DZSR Levels A and B, you’re ready to move on to DZSR Level C.
Typical Drones in this level: Video drones, drones with GPS, Racing drones.

DZSR Level D
If you’ve mastered drones at DZSR Levels A, B and C, you’re ready to move on to DZSR Level D.
Typical Drones in this level: High-end/custom quads/hexacopters, DIY quadcopters.
