RE-POST February: Access to SPO600 Servers

 This post would test the access to the SPO600 servers.

The instructor gave us access to two servers, one is the AArch64 machine, and the other x86_64 machine. Both systems run Fedora. The instructions on how to access them are at: https://toronto.tylers.info/dokuwiki-toronto/doku.php?id=spo600:spo600_servers (updated 2024-04-17 due to the previous wiki no longer working).

To get access to these servers, Linux distribution is required.

In my case, I wasn't able to access it since the SSH key that was given to the instructor was from my GitHub and not from my local machine. After, fixing that I was able to access both servers by inputting the following code on my bash terminal:

    
ssh -i <path to my SSH key> mdang10@aarch64-001.spo600.cdot.systems
    
ssh -i <path to my SSH key> mdang10@x86-001.spo600.cdot.systems

The code that I had to input was a bit different from the one stated in the instructions because I had to find the path of my SSH key and include it before accessing the servers.

Inside the terminal:

The system is never backed up, therefore, if we are making any changes, we can SCP or save our changes somewhere else.

To know what Fedora version both systems are using:

cat /etc/fedora-release

This output: Fedora release 35 (Thirty Five)

To change your password:

passwd

This is to be able to use sudo command.

We probably won't need to install any additional libraries and tools, since we already have a good set of tools.

Simplify SSH Access

In your local machine, create a ~/.ssh/config file:

    
Host "aarch64"
    
         hostname "aarch64-001.spo600.cdot.systems"
    
         user "YourUserID"
    
         identityfile "path to SSH key"

    
 Host "x86"
    
         hostname "x86-001.spo600.cdot.systems"
    
         user "YourUserID"
    
         identityfile "path to SSH key"
