Cooler CPU Coolers

Background
I have 10 Proxmox servers to maintain all are basically the same, AMD FX 8350 CPU and asus motherboards with several more servers coming soon. FX 8350's are known to run hot and stock coolers weak per web searches. AMD just released a new wraith Cooler to help this issue. Time to figure out if there is a issue and how to fix it if there is a problem.

Testing (this should work on any debian based system)
install these
sudo apt-get install lm-sensors (a program to check system sensors including temp)

Debian Service

I have found a couple Debian based distributions that have trouble turning off services at start up. To begin, services are background jobs that run on *nix systems. In compression to Windows they are what you can find by opening the task manager and finding the processes. You don't see the programs running because they are in the back ground. Most of these services are harmless but unnecessary. To stop a service in a Debian system type in the command.

sudo service servicename stop

or

sudo /etc/init.d/servicename stop

Useless cable/DSL modem info as noted from several recent projects

A question was asked about Cox cable modems and the need to do a custom routing to gain a external IP address The router is a Cisco DPQ3212 this one has VOIP. VOIP needs a IP address so you cannot by default turn off NAT or do a Transparent Bridge because the VOIP would need to be set up externally on another device, not inside the modem.

Secure Passwords

Many people who use a Linux Operating System believe that it is by definition a secure system and that they are in no danger. I was once told that Linux is like a room with all the doors and windows closed and locked. I have also been told that the only truly secure computer is one that is disconnected from the Internet, turned off, unplugged and battery removed (for laptops), and placed back in its box on the top shelf of the hall closet. The truth is probably some where in between.

linux installer fails to see a sda1 after the drive was used in a raid

Stump the installer. Last week we had another challenging install at the local installfest in that most installer programs would not see the HDD sda. server did work but no desktop versions. after going home I found this link http://ubuntuforums.org/showthread.php?t=2003675 checked and verified and even and format and new partition tables the drive still thought it was part of the raid. sudo dmraid -E -r /dev/sda fixed it and then all installer programs seemed to work fine
