This chapter is a collection of Questions & Answers
that have been treated by the
Computing Help Desk (UCO) managed by the User Support group.

Question - Windows Password
How can I avoid the Windows password prompt?
Answer -
You must delete the 'userid'.pwl file in your c:\w95
directory. Then logout and login again. Blank out all
entries at the (now last) windows password prompt and hit
'Cancel'. At next login time, you
will not be prompted for this password anymore (but only for the
"NICE password".
Question - PC Installation
I got a new PC and would need some information for its installation.
Answer - Look at the "Delivery Of a New PC" Web page provided by the PCDesktop team at URL:
http://nicewww.cern.ch/PCDesktop/Activities/Delivery.htm
Question - PC Fortran Compiler
I cannot find the Fortran Compiler on my PC.
Answer - On NICE the Fortran compiler is accessible from the menu "Software Engineering" :
Start / Software Engineering / Development / Fortran
If this menu is not visible for your login then you can add it by loading the "CERN Setting" window:
Start / Settings / Control Panel / CERN Settingthen select "Start Menu", and "Software Engineering".
Question - Accented characters on a PC with Exceed
Is it possible to type accented characters on a PC when
using Exceed?
N.B. User can do it with telnet (to RSPLUS) from his PC (using 'e to compose an e accent aigue), but it does not work when he connects to RSPLUS with Hummingbird Exceed.
Answer -
The problem is not related to the Exceed emulator but to UNIX
and X-Windows. Exceed has its own keyboard mapping (X protocol).
Therefore, you are not using the Windows keyboard settings
and you have the same problem as when using an X terminal
connected to a UNIX workstation. Please note that handling accented
characters in this environment is complex to manage from
an international keyboard.
One solution, but this probably works only with some keyboards
which allows you to type such special characters (e.g. suisse keyboard
allowing both german and french special characters) is the following:
This solution might also be system-dependent (the solution may
work for HPPLUS but not for RSPLUS).If your keyboard is not
allowing you to do this then you should contact the PC shop to
see what solution they can propose.
Another solution, which is a little "tricky" but independent
of the system, it to do a "cut and paste" for all these
special characters from the table given by the program "ascii-table"
available through ASIS in /usr/local/bin (just type the command
"ascii-table" on any UNIX central system).
N.B. using "telnet" from the PC opens a "Microsoft" window local to the PC
that may be capable to handle accents. By using Exceed you open
an "xterm" window (X11 protocol).

Question - Mail Server password from Unix/AFS accounts
I have accounts on different AFS-based machines (e.g. RSPLUS and
TH_WGS). When I log on TH_WGS and want to read my mail (from the
MAIL server) I must provide a password. Which password is it?
Can I suppress this password request ?
Answer -
The password you are asked is the password of the Mail Server
machine (MAILSERV).
If you do not know (or cannot remember) this password you can ask the
UCO Helpdesk (78888) to reset it
to a new value.
Please note that it is possible to register any machine (e.g.
TH_WGS)
so that you will not be asked anymore to provide this password. This can
be done by yourself, with the tool "xuserinfo".
On a UNIX central machine
(e.g. RSPLUS) just type the command "xuserinfo" and then:
However please note that this "pre-authentification" cannot be done
for an account with an id different from the one you have on the mail
server.
"HOST/Workstation for MAILSERV pre-authentification"
You can add here the name of the machine and the login where you want
to have "pre-authentification" (i.e. suppress the password request).
Select "help" (top line) and follow what is written.
Question - Set font with Exceed
I have a PC on NICE, and use Exceed to work on UNIX;
when I open a new "xterm" (simply calling 'xterm')
a new window opens, with large fonts.
How can I set the default font to be 'small', i.e. obtain
the same result as when I type 'xterm -fn fixed'?
Answer -
This is well explained in an article in CNL 223 ("Changing X Fonts"):
http://consult.cern.ch/cnl/223/node27.html
You have 2 possibilities:
.Xdefault or
~/.hepix/xresources if you use the HEPiX X11 scripts).
XTerm*Font: fixed
tcsh
then in .tcshrc you can set an alias like this:
alias xterm 'xterm -fn fixed'

Question - Fancy headings for my LaTeX files
Answer -
The author of fancyheadings.sty (Piet van Oostrum)
decided to rename his package to fancyhdr.sty for reasons
of MS-DOS compatibility, and he asked all maintainers of LaTeX
installations to delete the old version.
Question - Include a bitmap image into a LaTeX document
How can I include a bitmap image (e.g. gif) into my LaTeX document ?
Answer -
Convert it first to an On unix, use the routine .eps or .ps file !
'convert', e.g.:
Then - in Latex - use
convert lorem.gif lorem.eps
'\includegraphics'
NB: To get a list of image formats recognized by convert
type:
convert -h
Question - Edit PostScript files
Is it possible to edit PostScript files ? Are there any
applications (either on Unix or
Windows) that allow to edit PS files ?
Answer -
Publicly available at CERN you'll find the following possibilities:
Since you also mentioned that you might be interested in commercial products
there are several of them, e.g. "Adobe Illustrator" is one of the best known.
Furthermore, on "
pstoedit" which converts PS-files to
various other formats wich can be edited. "pstoedit" supports
the following outputs formats:
tgif: Tgif .obj format (for tgif version >= 3)
mif: (Frame)Maker Intermediate Format
fig: .fig format for xfig
pdf: Adobe's Portable Document Format
gnuplot: gnuplot format
ps: Flattened PostScript
dxf: CAD exchange format
sample: insert your new format here
N.B.: pstoedit only works with well formed PS-files, so sometimes it might
not be able to convert a file properly.
http://karlsberg.usask.ca/Postscript-FAQ.html" one finds the
following:
"How can I edit a PostScript picture?
If you know the PostScript programming language, just use any text
editor to edit the code directly.
If you want to do it visually, you can use Canvas on the Macintosh.
Arts & Letters software package from Computer Support Corporation
is supposed to be able to read arbitrary EPS files, using a
software converter called Decipher. Also, Island Graphics has a
trio of software packages called, appropriately, Island
Draw/Paint/Write. This is also supposed to include a full-blown
PostScript interpreter, and be able to read and edit arbitrary
PostScript files"
Question - STL Access
How can one access the Standard Template Libraries (STL) for C++ on the
CERN central systems?
Answer -
A link to the Object Space STL documentation can be found on:
http://wwwinfo.cern.ch/asd/lhc++/strategy.html
under "Standard C++ Libraries":
ObjectSpace implementation
Question - Netscape Plug-ins
How can I find out which Netscape Plug-ins are installed?
Answer -
On either UNIX or PC, in Netscape select:
This will give you a list and description of installed Plug-ins.
Help -> About Plug-ins
Question - Autocad and Backing Store
Running Autocad on my alpha workstation I get the
following error:
Autocad is only supported when running under AIXWindows with the Backing Store feature enabled. Exit AIXWindows and restart the X server by typing "xinit -- -bs".
Answer - This is not an error message but a warning. It should not prevent Autocad from working unless your workstation is equipped with a 24 bits graphics.
