Bitcoin mining on headless Ubuntu 12.04 server I've googled a lot and also read threads here but I'm still struggling.
Background:
I'm a eager but novice Linux user
I've an Ubuntu 12.04 webserver sitting pretty and is not doing much.
I would like to use the free processing power to mine Bitcoins - makes cents (sense).

Thus, I have Ubuntu 12.04. I have installed bitcoind and made a bitcoind.conf file as per Ubuntu Linux -- How do I start bitcoind as a service to run automatically?
(Basically, copy and paste)

I've installed bfgminer and I've register an account with Eclipse Mining Consortium (eclipsemc).

Now my questions:


I've read the bitcoin needs to download a large data file (+- 6Gb). 
I can't find any log files to tail.  How do I know bitcoind is
working properly? 

$ ps aux | grep bitcoind
1000     30080  0.0  0.0   9364   368 pts/1    D+   21:21   0:00 grep --color=auto bitcoind

When I run bfgminer (bfgminer -o http://eu.eclipsemc.com:8337 -u [MyUserName_worker] -p [password] -L bfgminer.log), I have to press "M", then "+" and enter "auto" before it will pick CPU 7 as the device.  How can I ensure that it will pick CPU 7 as the default device? How can I run this as a background process?
I still need a bitcoin wallet?  I'm using Armory on my Windows box, what is a compatible one for Ubuntu webserver?
How do I ensure that bitcoind and bfgminer doesn't kill my server?


Thank you very much!

It seems that CPU based mining is not viable any more.  Even going to other cryptocurrency, which difficulty level should rise quicker as people mining bitcoin using hardware will mine these too.

Ah well, missed the bus :)
