SSH to Student Server
The basics of logging in
We are going to login remotely with SSH1
If you are on Linux or Mac you need to open a Terminal. You can do this my searching for terminal in the applications menu.
If you are on Windows, you need to open Powershell. You can open this by clicking the start menu and searching for powershell.
Once we have our Shell open on our local machines we can attempt to connect to the student server with the following command:
ssh $USERNAME@student.computing.dcu.ie
Note
You should replace $USERNAME with your DCU username
The first time you connect you will get a message saying that SSH thinks that you have never connected to this server before.
This is normal and you can type the word yes and press Enter
The authenticity of host 'student.computing.dcu.ie (136.206.218.15)' can't be established.
ECDSA key fingerprint is SHA256:A7yV0cBdiWax/Ru3p4cKokh/ieS3tO7uZTQEt5ii+fE.
Are you sure you want to continue connecting (yes/no)?yes
After this message you will be asked to enter your password after the password prompt

The student server doesn't have a computer screen, so we need a way to access it and run commands on it remotely. Usually the application we run the commands in is called a Shell. SSH stands for SecureSHell, it allows us to connect remotly to run commands ↩
