Error when cloning GitHub repo over SSH

If you get ssh: connect to host github.com port 22: No route to host when cloning over SSH, use the following addition to your ssh config located at /nfs/home/cs.aau.dk/<aau-id>/.ssh/config:

host github.com
    HostName ssh.github.com
    Port 443

If you also get Bad owner or permissions on <path-to-config>, then remember to set correct permissions. A suggestion follows based on ssh man_page, but be careful that you are not exposing any of your private keys:

chmod 700 ~/.ssh
chmod 600 ~/.ssh/config

X11 forwarding

Currently (16/09/24) e.g. emacs gives a graphical interface if you are running an Xserver on your own machine and have enabled X11 forwarding.

Other workloads such as interactive matplotlib windows does not seem to function on the standard Ubuntu installation.

This is not a priority functionality. Offload the results to your own machine for further analysis.
