  • linux.cecs.pdx.edu
  • ruby.cecs.pdx.edu
  • rita.cecs.pdx.edu

Depending on your operating system, the error message will identify the location of the file that contains the reference to the old and now exired key. Delete that entry and you will be able to log into the system again.

This is part of the work we have been doing this week as described in this article:
