Instructions for logging into the ASCI-RED system

The instructions below will assist LANL users logging into the ASCI-RED machine at Sandia (janus.sandia.gov).

How do you login to janus.sandia.gov?

A short version:

From the ACL machines (wort,black,kent and maybe more) you can use the kerberos5 software.

kent>k5init or kinit -f your_dce_username@lanl.gov
password: your_dce_password



Acknowledgement and Disclaimer

If kinit doesn't recognize the -f flag, you need the version5 of kinit. You can copy it from asci kerberos webpage (You may need need a local SNL account to login to the webpage). For the version5 of kinit, all you need to enter is 'kinit -f'

>ssh janus.sandia.gov
password: your_dce_password

That's it. Note that if DCE is working right and you have done a (kerberos version 5) kinit, then ssh won't prompt you for a password.

To get an x11 emacs to display back to LANL.

First do your kinit:

kent> kinit -f your_dce_username@lanl.gov
password: your_dce_password

To start your regular shell on sasn100 from which you can start x11 emacs :

The x11 session is encrypted over the open network for security.

kent> xterm -e /usr/local/bin/ssh sasn100.sandia.gov &

or, to start just an x11 app (such as emacs) on sasn100:

kent> ssh -n sasn100.sandia.gov emacs &

If you have any questions, email janus-help@sandia.gov
