Updated Turing Server
During the summer break, the Network Staff updated the Turing server to remove it from it's virtual environment and update the OS. Turing is now running on bare metal and is CentOS 6.4.
The SSH keys were changed during the update of Turing and you will likely need to remove Turing's SSH keys from your system. We have instructions on how to do so at http://www.cs.olemiss.edu/help/ssh_key_removal
