T0a: Introduction Computer:
shell, command-line, connecting, editing, plotting

This tutorial will be concerned with configuring your laptops to connect to our computers, for you to be ready to run your first simulations in the next tutorial (T0b).
This regards the following programs:

• a secure shell client (ssh),
• an X server (optional but recommended).

Please bring your laptops to the tutorial so that we can help you set these programs up.

1.

Make sure that you have installed the VPN client.

2a.

If you have a working X11 environment running on your Laptop (e.g., on a Linux operating system), then you can just do

ssh -4 -Y hydro@mpusm06.usm.uni-muenchen.de

The password will be announced in the tutorial.

2b.

If you do not have a working X11 environment:

on Windows:

install the Cygwin package.

on macOS:

install the XQuartz package.

Start the X server and see if you can open local clients like xterm or xeyes from the command line. Then continue with 2a.

In case you want to run the first simulations directly on your laptops, you will need:

• a C++ compiler
• a text editor (such as emacs or vim)
• a plotting program (for example, gnuplot or Python+matplotlib)
