Introduction

A number of login hosts running Linux are available at the IT department. Currently this is a provisional setup meant as the first phase of a transition of our department desktop environment from Sun/Oracle Solaris to a RedHat clone (currently Scientific Linux later CentOS), wherefore a few restrictions apply:

  • Avoid using filenames with non-ASCII characters (such as å, ä and ö), as the file server and client systems use incompatible encodings for those. If you currently have such files in your home directory, their names may appear garbled in listings.

Logging in

From a Sunray:

  • Give the command linuxlogin to a shell window on your Sunray desktop. It connects to a Linux host chosen by random from the pool of available machines, creating an xterm window on the Linux host running your login shell, without any need (or possibility) to supply a username and a password.
  • It is also possible to connect to a specific host using the command
    xrlogin hostname

When logged in to a Sunray server through another computer:

  • Give the command
    rlogin hostname
  • Note: You will not get the X environment automatically set up this way.

In case you encounter error messages or other problems logging in, it may be that your current init files depend on certain features in our Solaris environment not available under Scientific Linux. Please notify us of such problems if you can't easily fix them yourself, or you expect your colleagues to encounter the same problems.

Available resources

We have the following configurations/servers today:

  1. CPU: AMD Opteron (Bulldozer) 6282SE, 2.6 GHz, 16-core, dual socket
    • Memory: 128 GB
    • Operating system: Scientific Linux 6.5
    • Student servers:
      • tussilago.it.uu.se
      • vitsippa.it.uu.se
    • Employee servers:
      • benved.it.uu.se
      • brakved.it.uu.se
  2. CPU: AMD Opteron (Bulldozer) 6274, 2.2 GHz, 16-cores, dual socket
    • Memory: 128 GB
    • Operating system: Scientific Linux 6.5
    • Student server: gullviva.it.uu.se
    • Employee server: hagtorn.it.uu.se

The hosts mount user home directories, project directories and similar from the existing department file systems. The software installed is however specific to the Linux hosts, and initially limited to meet currently known demand. Significant software packages are:

  • Matlab 9.0 (R2016a)
  • Maple 17
  • Comsol Multiphysics 5.2a

If you have a need for some additional software not yet installed, please file a support request.
