===========================
Logging into an UNIX server                                             [TOC]
===========================

In order to connect to our Unix server you need a secure shell (__ssh__). For
the first quiz this will be sufficient. However, for later assignment you also
need an __X11__ server on your own machine. On this page you get information
on how to install and configure these tools depending on the operating system
you are using.

For Linux users
===============
Usually everything you need is already installed. For the configuration just
watch the video for MacOS, it is pretty much the same. Just ignore the
instructions on downloading an X11 server. In case you have some exotic
distribution where things are not working out of the box (actually I can not
imagine that) let me know.

For Windows users
=================
The tool __PuTTY__ is very popular on Windows for connecting to Unix machine.
However, I was told that using it together with an X11 server is not as easy.

It seems that installing __CygWin__ is the easiest way to get a usable
terminal, a secure shell and an X11 server on windows. Thanks to my
coworker __Laura Burr__ there is a video that shows the installation step by
step.
