Instructions for logging into the ASCI-RED system

How do you login to janus.sandia.gov or sasn100.sandia.gov?

A short version:

From any workstation or login server (i.e. k2) on the LLNL internal network, you can use secure shell (ssh) and your DCE password:

k2.llnl.gov{pwork}44: ssh -l <_dce_username>@spectrum.llnl.gov janus.sandia.gov
password: <_your_dce_password>



Acknowledgement and Disclaimer

To get an x11 emacs to display back to LLNL when starting from k2. First login to sasn100 or janus. Then start x11 emacs : (The x11 session is encrypted over the open network for security.)

sasn100> emacs &

For machines which use the DCE environment and have the Kerberos5 software
loaded (i.e. blue):
blue199{pwork}22: /usr/local/krb5/bin/kinit -f pwork
Password for pwork@spectrum.llnl.gov: 
blue199{pwork}23: ssh sasn100.sandia.gov

and you're in.  With this method you no longer need to type in your password
as long as the Kerberos credentials remain valid.  You can exit and go back to
either sasn100 or janus without having to type in your password.  You can also
exeucte commands such as emacs remotely using ssh:

blue199{pwork}27: ssh -n sasn100.sandia.gov emacs &
