If you have a TeraGrid allocation, use one of the following hostnames for interactive use:

If you are at IU and have a TeraGrid allocation, you can also use SFTP to connect to bigred.teragrid.iu.edu to copy your SSH key to Big Red before using login.bigred.iu.teragrid.org to run grid-enabled software.
