Accessing School of Computing Remote SSH Servers

As part of a recent campus-wide change, the Office of Information Technology (OIT) has implemented Microsoft Authenticator for two-factor authentication (2FA) across our systems. However, because Microsoft Authenticator does not support Linux-based logins, the School of Computing has transitioned to SSH key pairs as our 2FA authentication method for Linux services until a better option becomes available.

To access any School of Computing remote SSH servers, you must register the public portion of your SSH key. This setup is essential for services such as:

• SSH access to linux personal website nodes like pc00.cs.siu.edu and pc01.cs.siu.edu
  • These allow updating personal academic websites hosted at the School of Computing (e.g., https://www2.cs.siu.edu/~siu851234567)
• SSH access to research lab servers

Instructions for SSH Key Registration:

Please follow the steps outlined in the SSH Key Setup Instructions to register your public key and begin accessing School of Computing services.

Faculty that would prefer to set up a personalized alias for your School of Computing personal website URL (such as replacing siu851234567 with a more user-friendly name), feel free to email the system administrator listed below with your preferred alias.

Thank you for your cooperation as we transition to this more secure and efficient system.
