Desktop hosts

Most users in the TCS are using SunRay thin clients. The SunRay:s will bind to one of three machines:

• tcs-ray.nada.kth.se (Sparc, Solaris 10)
• rungner.nada.kth.se (Sparc, Solaris 10)
• tray.nada.kth.se (x86-64, OpenSolaris)

N.B. the domain names here are nada.kth.se, not csc.kth.se. These are joint resources, please don't run heavy jobs on them

Accessing hosts remotely

The system group has some documentation on remote access, which can be found on: [1].

Remote host access is done over ssh. In addition to your desktop machine, you can try:

• my.nada.kth.se
• faun.nada.kth.se

N.B. the domain names here are nada.kth.se, not csc.kth.se.

Note that since we use Kerberos, ssh keys are not supported for logins, so you'll need to do password logins.

Problems with sftp/scp

A common cause could be that some path is not set up correctly for non-interactive shells, or that your login scripts print something. See [2] for slightly more information.

Computer-intensive jobs

For computer-intensive jobs, there is a shared machine called swift.nada.kth.se (which is rather old, and not particularly swift anymore). tray is a much better option currently, as long as you load it in a nice way, since tray is being used as a desktop machine.

Another option is to try to get computer time at PDC.
