 In order to access Departmental systems externally (eg. from your home), you will first need to connect to a time sharing server.  From there, you can SSH to any other Departmental server.
-If you are an undergrad, you will use the time sharing server named "red.eecs.yorku.ca".  If you are anyone else, you will use the time sharing server named "indigo.eecs.yorku.ca".

 ===== SSH Clients =====

 There are a number of available SSH clients for Unix, Windows and Mac machines.  Unix and Mac users typically use "ssh" from the command line like this:
-  % ssh indigo.eecs.yorku.ca -l <EECS USERNAME>
+  % ssh indigo.eecs.yorku.ca -l <EECS USERNAME>  or
+  % ssh red.eecs.yorku.ca -l <EECS USERNAME>
-Windows 10 users can use the SSH command line tool as well.  However, most Windows users prefer a GUI.  For that, we recommend [[https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html|Putty]].

 ===== SSH From One Host To Another Without Entering A Password =====
-As mentioned above, you can SSH from any tech-supported Linux system to any other tech-supported Linux system without requiring a password. If you would like to be able to connect to a non-tech-supported SSH server (eg. your personal Ubuntu workstation) without entering a password, you will need to carry out a simple two-step process yourself.

 First, run 'ssh-keygen' on one of the Departmental Unix hosts:

 Enter file in which to save the key (/eecs/home/xxx/.ssh/id_rsa):
-Hit "ENTER".  The public ke file (.ssh/id_rsa.pub) and the private key file (.ssh/id_rsa) will be created.
+Hit "ENTER".  The public key file (~/.ssh/id_rsa.pub) and the private key file (~/.ssh/id_rsa) will be created.

-On the system that you would like to login without password, you will now need to append the contents of the newly created .ssh/id_rsa.pub file to the authorized_keys file (eg ~/.ssh/authorized_keys on Linux systems). If the file does not exist, create it. Now, you will be able to ssh from your host to the other machine without requiring a password.
