A:

Scanners are extremly bad supported on Linux. There is a scanner in every secretariat.

Q:

Is there a backup of my data?

A:

Home directories as well as some special areas are backuped every night to the Rechenzentrum (computing center). Lost data can be recovered from there by an administrator.

Q:

How do I start a batch-jobs on the CONDOR Systems?

A:

On most of the Linux-PCs the Batch-System CONDOR is installed. Via this system cpu-consuming programms can autmatically be delivered to the fastest currently available system so there is no need to search for an available system and start the program in interactive mode.

Q:

Where do i find more information on the CONDOR system?

A:

Here You find additional informations on CONDOR.

Q:

Where do find usage statistics of the CONDOR-Pool?

A:

The usage statistics are available on the CondorView-Webinterface .

Q:

Which printers are available?

A:

There is a list of available printers in the submenu for infrastructure.

Q:

How can I use the printers from my laptop?

A:

The printing queues of the CUPS-printservers lxtspr1 (IP 134.61.10.7) and lxtssp1 (IP 134.61.10.8) can be accessed via IPP protocol.
If the system does not automatically find the CUPS server, the connection can be established manually. On Linux und Mac OS X you have to define an IPP-connection
ipp://134.61.10.7:631/printers/lpthp1-d
on Windows you define (as network printer)
http://134.61.10.7:631/printers/lpthp1-d

You may have to install additional drivers.

Q:

Which distrubutions are supported?

A:

We only support the (open)SUSE Linux distributions. On the Desktop systems there is version 11.3 installed; the Dual-Opteron-Cluster is running SLES9.

Q:

How to setup my mail client?

A:

Setup for a local mail client (for pine see berlow)

• SMTP-Server (no SSL): relay.rwth-aachen.de oder
  SMTP-Server (with SSL and authentification): relay-auth.rwth-aachen.de
• Incoming-Server: mailbox.rwth-aachen.de
• Account: <username>+physik.rwth-aachen.de

Further informationen are given by the Rechenzentrum (computing center).

Users of the mail client pine have to set some variables:

inbox-path={mailbox.rwth-aachen.de/ssl/imap/user=<username>+physik.rwth-aachen.de}inbox
smtp-server=relay.rwth-aachen.de or
smtp-server=relay-auth.rwth-aachen.de/ssl/user=<username>+physik.rwth-aachen.de
user-domain=physik.rwth-aachen.de

The parameter ssl in inbox-path makes pine setup an encrypted connection to the server and the passwort is not transmitted as clear text. The paramter imap is optional as this protocol is the default one.

Q:

How to configure my Mail account?

A:

There is a Webinterface http://mailadm.rwth-aachen.de for configuration. The credentials are:

• User-ID: <username>
• Domain: physik.rwth-aachen.de
• Password: <password>

Q:

Is there a Webmailer?

A:

There is a Webmailer (Java based) at http://webmail.rwth-aachen.de. You log in with:

• user ID: <username>+physik.rwth-aachen.de
• password: <password>

Q:

How to save disk space with my mail client?

A:

Some mail client programs such as Thunderbird, Mozilla, Seamonkey, ... locally save Mail in the so-called mailbox format. If You delete mails those mailbox files do not shrink autmatically! You have to choose "Compact folders" from the menu. You do not loose any mails they are just kind of re-arranged in this mailbox file. So please compact Your folders from time to time otherwise You may run out of disk space.

Q:

Is there a mailing list I should be on?

A:

All members of the Institute for Theoretical Physics should be reached via the mailing list itp(at)lists.rwth-aachen.de.

If You are not on this list please subscribe .

Q:

How to edit Microsoft-Word-Documents on Linux?

A:

OpenOffice/LibreOffice is installed on all systems and is highly compatible to the Microsoft formats.

Q:

How to get access to a Windows-System?

A:

You may connect to a Windows 2003 Server via rdesktop. On this Windows system the most important programs are installed with a sufficient number of licenses:
rdesktop -d PHYSIK -g 90% -a 16 winsrv
You have to log in with Your  CIP-Pool account. Further questions should be directed to EDV-Support.

Q:

How to connect to my system from outside the physics institute?

A:

SSH access is granted from dedicated domains to:

• lxtsac1.physik.rwth-aachen.de
• lxtsac2.physik.rwth-aachen.de
• portal.physik.rwth-aachen.de (CIP-Pool)

"CIP-Pool" means You have to use Your CIP-Pool account. If Your domain is not allowed for access please contact the administrators of the Institute of Theoretical  Physics.

Q:

Which compilers are available?

A:

The current compilers of the GNU Compiler Collection (GCC) are installed. For compatibility reasons g77, gcc und g++ are available as of version Version 3.3.6 (see below).

Q:

Is there no  F77-compiler any longer?

A:

The current GCC does not contain/support F77-compilers! An old version 3.3.3 compiler is available as g77-3.3. It seems that code generated by this g77-compiler is not compatible with code generated by the system C/C++-compilers of version 4.3.x. Therefore a complete gcc-suite of version 3.3.6 including  g77, gcc and g++ has been installed under  /usr/local/opt/gcc-3.3.6. They are available as g77-336 etc. . As they are not integrated in the system You may have to adjust paths to Include-Files und Libraries manually.

Q:

Where are the Intel-Compilers?

A:

Intel-Compilers are no longer free for academic use and licenses have to be bought. For further informationen please ask the administrators.

Q:

Which libraries are available?

A:

In the Software-Listing You find the available Libraries as CERNLIB 2005,  ROOT etc..
