Switching DNS in Ubuntu Linux

One approach to switch among different development environments (QA, Integration, Stage, etc) is to have different DNS configs for routing one domain.

In Ubuntu you can setup different network connections with different DNS servers and be able to switch from network top menu,

1. Simply add a new network connection (may need two, one for Ethernet and one for WiFi)

2. Configure DNS settings

3. Switch to new connection from top menu

4. Test with nslookup command

ATG Colorizer: libstdc++.so.6: cannot open shared object file: No such file or directory

I was in the middle of my ATG local dev environment setup and started to see an error with small application ATG Colorizer:

libstdc++.so.6: cannot open shared object file: No such file or directory

I tried installing the library as I have done in the past, but somehow my new Ubuntu stopped liking the old install recipe. After checking the web for a while I found a way she liked: 

apt-get install lib32stdc++6
