Using CommVault 1-touch restore

I have been attempting on and off for a few weeks to get CommVault's "Virtualize Me" feature working in my environment. My environment is a little unique in the fact that the DR VMware systems are isolated from the CommServe. Because the CommServe needs access to Virtual Center to use Virtualize Me, there is a problem. We looked at differnt options such as moving servers and creating static NAT rules, but none of them were very flexible or secure.

A little searching and I found a great post about CommVault 1-Touch. Virtualize Me is essentially 1-Touch, but automated for VMware deployments. The benefit of 1-Touch is that it is used to restore to any system, not just VMware.

To use 1-Touch you have to pre-create and configure the VM hardware (CPU, RAM, disk, network, etc...) Then boot to the ISO and walk through the setup process..

Another method to extract music from YouTube

Previously I created a post that described how to extract music from YouTube using a variety of Linux tools. I am getting ready for a road-trip and needed some theme music (Mustang Sally, Slow Ride, etc...), but didnt have a Linux system available. So here is another method using Windows tools.

DISCLAIMER: I am not fully aware of the legality of this. I am assuming that it is OK since I am not doing any hacking or breaking of cryptography, but your mileage may vary.

Tools needed

Step 1: Find the video you want
This is the easy part, just search YouTube for the video you want. 
It may be a good idea to listen to it before hand to ensure it is the version you want. There are a lot of remixes and covers by other bands (professional or otherwise). You wouldn't want to download a heavy metal song and find out later that its a polka remix

Step 2: Download the video
Use Free YouTube Download to download the video to your computer. I found the default quality and format settings to work fine.

Step 3: Extract the audio

Using VLC, walk through the Convert process to extract the music as an MP3.
If you have a lot of files, you can use the following command to bulk convert them.
for %i in (*.mp4) do "c:\program files\videolan\vlc\vlc.exe" "%i" --sout #transcode{acodec=mp3}:duplicate{dst=std{access=file,mux=raw,dst=\""%i.mp3"\"},select=\"novideo\"} vlc://quit

Monitoring wireless networks

I just rebuilt my laptop and was in the process of reinstalling all my normal tools (7zip, Chrome, wireshark, etc...) I suddenly remembered that I had a great wireless monitoring tool that allowed me to see what networks were nearby, what channel they were on, and how strong their signals were over time, but I couldn't remember its name.

A little googling and I found it - inSSIDer (

The really great thing however, is that I found several other methods to do the same thing. For my Android phone there is WiFi Analyzer (, and Windows can even perform similar tasks natively by running netsh wlan show networks mode=bssid
