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

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

• u-shell.csc.kth.se, runs Ubuntu and works well
• 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 or setup Kerberos tickets.

More information from the systems group. You will find there information about Kerberos.

Accessing e-mail

You are given to accounts, @kth.se and @csc.kth.se. It is strongly recommended to use your CSC account, because there have been problems with central accounts.

All the information regarding e-mail is at the CSC webpage: https://www.kth.se/csc/it-support-csc/services/email?l=en_UK

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 [1] 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.

Equipment

As an employee of our department you are supposed to have some working equipment. Some of them are listed here

• Monitors (Screens): you can have a 24 inches LCD on your desk at your office. If you don't have it you can contact Torbjörn Granlund. He will help you to get one.
• Nettops: we have some negotiations for getting some new nettops for every employee at our department. The latest news about these negotiations can be gained from Karl Palmskog.
