Student websites will remain but the compute nodes may be decommissioned in the future.
All activeÌýIdentiKey users on the CSCI career track have access to this service. SSH intoÌýelra.cs.colorado.edu, which consist of the following hosts running Ubuntu 20.04:
- elra-01.cs.colorado.edu
- elra-02.cs.colorado.edu
- elra-03.cs.colorado.edu
- elra-04.cs.colorado.edu
You can either SSH into the round-robin address (elra.cs.colorado.edu) or directly into a specific node. All nodes share the same home directory.
In addition, there is a separate node that runs Red Hat Enterprise Linux 7.
- elra-sql.cs.colorado.edu
A shell can be set globally in theÌý. This isÌý/bin/bashÌýby default.
