Shell introduction§

As member of Couchdesign you can get a shell account at xayide.jones.dk.

A shell account provides you a "home" at the system, that you can access with a command-line console interface either interactively or automated by scripts.

You need to contact_sysadmins to get your shell account created. Provide your full name, email, and cellphone number, which is shared with all users for use in case of problems with your account. You may also suggest a name for your account (only lower-case simple letters).

Remote access§

Your shell environment is accessed via Secure Shell (ssh) authenticated by one or more public keys that you provide.

Ssh public keys are stored on your own computer.

Existing public keys can often be shown like this:

cat ~/.ssh/id_*.pub

You can create a new key with a command like this:

ssh-keygen -t ed25519

On Windows systems above does not work, and you can instead try use the tool PuTTY.

Mosh§

Regular SSH access require a reliable and responsive internet access.

Optionally you can use the SSH wrapper tool Mosh which allows your shell sessions to survive disruptive connections.
