View source for Logging in to a terminal session

* All our servers run Linux
** PLEASE NOTE, YOU'LL NEED A BASIC KNOWLEDGE OF LINUX TO INTERACT WITH OUR SERVER ENVIRONMENT
** If you need an introduction to Linux, we would recommend: [http://linuxcommand.org The Linux Command Line].
* You would usually log into our head (login node). It is called wonko.bi.up.ac.za.
* Logging in directly to our compute servers is disabled. You need to run your jobs using the [http://wiki.bi.up.ac.za/wiki/index.php/Running_jobs_on_our_servers queueing] system. 
* If you have a highly specific need to directly log in to one of the compute servers, please discuss it with our system administrator  (johann.swart at up.ac.za).
* An example from a Linux or Mac terminal session:
<source lang="c">
> ssh username@wonko.bi.up.ac.za
</source>
or if graphics forwarding is needed:
<source lang="c">
> ssh -X user@wonko.bi.up.ac.za
</source>
* For Mac, [https://www.xquartz.org/ XQuartz] needs to be installed for graphics to work.
* On newer versions of MacOS, you need to use:
<source lang="c">
> ssh -Y user@wonko.bi.up.ac.za
</source>
* If you are logging in from a Windows machine, you can use a terminal emulator such as [http://www.putty.org putty], [http://www.bitvise.com BitVise] or [https://ttssh2.osdn.jp TeraTerm].
** The hostname would be wonko.bi.up.ac.za, the user name would be the user name provided to you, and the authentication method would be password.
* If you need to use graphics from a Windows client, you can download [https://sourceforge.net/projects/xming XMing].
