[Service Upgrade] LINUX.GP Upgrade Scheduled 7/31/2016

DAY/DATE: Sunday, July 31, 2016

TIME: Evening

SERVICE AFFECTED: General purpose Linux machines, linux.gp.cs.cmu.edu

DETAILS:

On Sunday, July 31, 2016 SCS Computing Facilities will upgrade the general purpose Linux computing environment (linux.gp.cs.cmu.edu).

This will result in new ssh host keys being generated for these machines.

The currently valid SSH key fingerprints can be verified at the following URL:

https://webiso.cs.cmu.edu/key-fingerprints.txt

WHAT DO I NEED TO DO?:

SCS Computing Facilities Linux systems: An updated SSH host key list will be automatically obtained overnight by SCS Computing Facilities supported Linux systems. Until then, you can use the URL above to verify the fingerprints for linux.gp.cs.cmu.edu. Users with existing kerberos tickets will need to renew them.

Windows/Mac OS X/Self-installed Linux systems: Specific instructions for updating the saved fingerprint vary by client. Please contact the SCS Help Desk or assistance re-connecting to linux.gp.cs.cmu.edu and include the name of the program you are using to connect to linux.gp.cs.cmu.edu.

Please contact help at cs.cmu.edu or call the SCS Help Desk (x8-4231) if you have any questions.

Thank you for your attention,

SCS Help Desk
