CS240: C Programming requires you to write all of your code in Vim on a PurdueCS-hosted server.

By default, this would mean that you have to type in your Purdue credentials and pass DUO 2-factor authentication every single time.

This is where SSH comes in :D

  • if you want to make an ssh key, run the ssh-gen command (just google it)

  • you can find ssh keys in the .ssh/ dir on your own computer

    • config file within .ssh/ directory

      UseKeychain yes
AddKeysToAgent yes

Host data
    User kang616
      • Host names
      • User usernames
      • Keychain
        • contains every password, ssh key, wifi password, etc. that ive ever used

    • ssh key

    • ssh key pub (paste this into wherever to ssh into there (ex. data.cs.purdue.edu)

    • known hosts (list of servers you have ssh-ed into before)

      • every time you ssh into a server for the first time you are prompted to

  • oracle oc06 ssh

    • add ip address with ‘sudo nano ~/etc/home’

  • data.cs.purdue.edu ssh

    • pinging data.cs.purdue.edu to find the ip address
    • add ip address with sudo ~/etc/homes
    • ssh data works :D

  • OR borg01 ssh method

    • in .ssh/config
    • add Hostname borg01.cs.purdue.edu

  • visual studio ssh into data

    • F1 → Remote-SSH: Connect to Host
    • (therefore can cursor ssh into data)

2/7/2025 note:

  • added borg01 to .ssh config
  • ssh [email protected] works ‼️
  • but ssh borg01 doesnt work 😔
    • gotta set up etc/hosts
    • sudo nano /etc/homes

2/9/2025 note: check borg01 method or sudo NANO!!! etc hosts
