1) Concept of computing facilities

We have to define two environments: one is the "user environment" and the other is the "computing environment"

With "user environment" I mean the 2 elements "hardware" and "software" directly related with the user, i.e. monitor, keyboard and mouse for the hardware and GUI (graphical user interface) for the software. This last item imply also an operating system (UNIX type as Solaris, AIX, LINUS etc. or PC type like Windows 95 or NT or W2K).

With "computing environment" I mean all the hard- and software which is somewhere at disposition of the user. I am thinking here of the many type of servers we have for disk services or number crunching services.

Users should sit in front of a machine with a GUI that they like. Thanks to the X11 concepts and the corresponding software (X11, OpenWind, CDE and programs like "WinCenter" on the UNIX side and Windows with "Xoftware" or 'Exodus' at the PC side ) we can always works with many different environments. Thus from this point of view it is not so important if one is working with a PC or a workstation (of course there are other points to consider).

As stated above, every user should be able to "rlogin" to another computer in our network. Please, from now on do NOT use anymore the command 'rlogin' but use instead ssh or xssh.
Expensive hardware like huge RAM and quick CPUs are concentrated on a few UNIX machines in order to garantie that our investment is well used and do not stay idle around and can be accessed from your desktop. For this we have to establish rules. See for instance "rules for remote jobs" .

3)Home directories

Our users have their home directory on our RAID-5 system.
 

All home directories will be automounted so that you will see

/home/user_name as your home directory.

Use the command:

quotack

to see the disk space used and the disk space left to you
The command  "gdf -h ."  do NOT gives any information about the disk space left for your account!!!
It just inform you about to space left on the physical defice where your home directory reside and

which you share with (many) other users!
