Remote login via SSH

ssh, the secure shell, is a way to establish a connection between two computers. In fact, you use it to login on a remote computer system, e.g. when you connect to our local computer system from home. Typically, you will have to provide a user name and a password to establish the connection. In our case, the authentication is done via a certificate that we provide you with at the beginning of the course1).

Things you need to have

  1. an email with a zip archive containing the openssh certificate, a key and the password
  2. your user name in our system. The file name of the zip archive (without the ending .zip) should be your username2) in our system. Typically, this will follow one of the three naming schemes
    1. ecoevo01, ecoevo02, etc
    2. pbioc01, pbioc02, etc
    3. mbwt01, mbwt02, etc

    Do you get the idea? It can happen that the zip file starts with something like 'ssh-' before your user name, then please ignore this in the steps further below.

    If you are unsure that you got the right username, ask the tutors. Using the wrong name will give you quite some headaches further down…

  3. the unpacked zip archive containing the following files
    1. openssh (the certificate)
    2. openssh.pub (the public key3)
    3. password.txt (a text file with your password for the ssh connection4)
  4. an open terminal/shell
  5. The IP address of our gateway: 141.2.46.150
1)
We do this only when it will be an online course
2)
we use username and account name synonymously in this WIKI
3)
you don't have to bother with this file
4)
this is not your password for the login within our system
