Computer Information

List of potentially bad WEB pages on our server

The Computer system

• Leif, Anders B and Anders N are responsible for the computer system. Locally stored manuals for many programs and more information are available on the computer page. Print commands

  • Here is info about print commands for different operating systems.

  Document processing commands

  • xemacs General editor. In particular it has special functionality for handlig LaTeX documents.

  • latex Compile a Latex document to a DVI file. Note that the department has local classes for reports, slides, exams, etc. Always use the schoolbook package for nicer and correct fonts. Two very useful packages are amsmath (for mathematical expressions) and psfrag (for replacing text in postscript figures).

  • dvips Convert a DVI file to postscript. Sometimes you need to invoke this manually to get the correct paper size (using the -t <papertype> option).

  • bibtex Compile the bibliography for a Latex document.

  • gv View postscript files. Can also read most PDF files.

  • booklet Shrink and convert a postscript document into booklet format, convenient for documents up to about 40 pages. Use e.g. booklet file.ps | lpr

  • psnup Puts multiple pages of a Postscript file onto each physical sheet of paper.

  • dvipdf Convert a .dvi file to .pdf

  • ps2pdf Convert a postscript file to PDF.

  • acroread View PDF files.

  • jpeg2ps Convert a JPEG image to postscript, without increasing the size of the file.

  Miscellaneous useful commands

  • quota Type quota -v to display disk usage and limits.

  • groups Print the groups you belong to. Ask Leif when you need to be added to more groups (e.g. if you're teaching a certain course). More tips and tricks can be found here.

  Some important computers

  • sperry-01, sperry-02, sperry-03 File server, mail server, etc.

  • gronwall The Windows computer located in the seminar room.

  • maxwell Web server. You can also use maxwell as compute server or to login from outside.

  User directories and backup

  • The home directories are backed up daily. Ask Leif or Anders B if you need to restore some files. Only place files that really need backup in your home directory (/home/username/)! Place all other files (downloaded documents, programs, mp3's, etc.) on your local hard drive (/work/username/). Leif will set up this directory for you if it doesn't exist. It can sometimes be useful to "borrow" material from people who have left the department. Have a look under /work/oldusers/

  Webmail

  • You can access your mail from outside the department using the Webmail at https://webmail.lu.se.

  Mailing lists
  • Important mailing lists:

  • regler.dis All department employees

  • guests.dis Current visitors

  • doktorander.dis All PhD students

  • junkmail.dis Misc. people, less serious content

  • Some mailing lists related to social activities: ib.dis, skrylle.dis, film.dis. To study the lists and find their owners, look at the file /etc/mail/mailhost_aliases on imap.control.lth.se

  Lab computers
  • The lab computers can have different login domains:
