[LBo] Loopback tip

[Allen]

I was installing a package that was both a client and a server 
and it connected through loopback. Well, it didn't and I 
scratched my head and then had an Ah Hah! moment. I opened the 
hosts file and added an extra line:

127.0.0.1:3306  localhost

The 3306 was the port that needed to be open. Saved it and it 
worked. P.S. Don't forget the colon and no spaces allowed.

Now I can't tell you why it didn't automagically open the right 
port on its own but this was an easy fix.

Best,

Allen
