-The CfN cluster is a linux-based system (CentOS 6.6). You connect to it using //ssh//, a tool for remote secure connections between computers. The initial connection and your interaction with the cluster are done using a standard linux //shell// environment (aka 'command line', 'command line interface (CLI)' or 'terminal'). This is a text window where you type commands and get text back as a response. +The CfN cluster is a linux-based system (CentOS 6.9).

 +====== Some Useful Linux Things =====
 +
 +==== Screen & tmux ====
 +
 +The ''screen'' and ''tmux'' tools are very useful. They let you create multiple terminal instances from one screen, and most importantly, let you 'detach' from a terminal instance/session and reconnect to it later, even if you've logged out, or lost your network connection or have closed your terminal window. This is **very** useful for running a long terminal program without having to keep your terminal and computer running.
