Logging Into Triton Using SSH

Getting a Login to Access Triton

Allocations on Triton are managed through the Triton Affiliates and Partners Program, or TAPP. For details, please visit the TAPP page. Once you have an allocation on Triton, either through TAPP or a campus project, you will need a user account on the system to allow access and run jobs.

First Login to Triton

User accounts for UCSD personnel are synchronized with the UCSD Active Directory (AD) service. If you have a UCSD AD account, you will use that username and password to authenticate to Triton. If you do not already have a UCSD AD account, one will be created for you during the account setup process.

Note that SDSC AD accounts are not the same as UCSD AD accounts. These two systems are currently not synchronized, even if the usernames are the same by coincidence. Authentication via SDSC AD is not supported on Triton, so be sure to enter your UCSD password to login.

If you need to change your password

If you need to reset your UCSD AD password, you may do so at the Change Password page on Blink.

Local ssh keys are created on Triton to facilitate access to non-login nodes in support of parallel job execution. These keys are not used to access Triton from outside.

If you are not affiliated with UCSD or SDSC

For non-UCSD users, new login accounts will be set up on Triton. Users will work with TAPP and the Triton administrators to have these accounts created. Access will require an external ssh keypair with passphrase authentication, and the public key will be installed in the user's home directory on the Triton login node(s). The TAPP Program Manager will assist users in this process.
