A: To print pages 17 through 24 of myfile.dvi type dvips -p 17 -l 24 myfile

---

A: When this happens for Lexmark printers, check the Finshing menu on the printer control panel (push the right arrow button twice, then select.) There should be a duplex option, and it should be set to OFF. If there is no duplex option, turn the printer off and on and check again. If it's set to ON push the right button and push select. Then push the Go button.
A: When this happens for HP printers, from the Main Menu go to Configure Device Menu, then Printing Menu and then selct DUPLEX option. It should be ON by default. If not change it to ON. If there is no duplex option, turn the printer off and on and check again. If it's set to OFF change it to ON.
If these instructions don't work, send email to consult@math.uic.edu.

---

A: As of 5/3/01, the way to join the mathgrad list is to send a request to mgsa@math.uic.edu. Send email to uicmath-request@listserv.uic.edu to subscribe to the uicmath list.

---

A: Use the command lprm. Usually, you just have to type this in to a terminal window and your job will be cancelled. If you're printing on some printer other than the default, you'll have to give the full name of the printer -- e.g. lprm -Psimplex2. You can check that this worked by using the lpq or lpstat -t command.

If a print job is wasting a lot of paper and you can't cancel it, turn the printer off and send email to consult@math.uic.edu right away. 

---

A: Type quota to see your disk space usage.



You can find the extremely large files in your account by typing the following commands:

find ~ -size +10000 -print

You should seriously consider deleting any files that are found by this command. You can find moderately large files using the command

find ~ -size +1000 -print

If it is convenient for you to delete the files found by this command, please do.

Some files can be made smaller by compressing them. On math.uic.edu, use the command gzip filename to compress files. You can later uncompress them using the command gunzip filename.gz

---

A: The file's permissions probably don't allow anyone but yourself to read it. You can change this by typing chmod a+r filename.html. Your files should be created this way by default to prevent your quizzes and grade sheets from being readable by everyone with an account on our system (e.g. Math 210 students.) 

---

A:It is highly likely that your machine has been filtered due to excessive uploading of data (more than 2GB). This generally happens due to use of torrent clients or if your computer has been hacked(it may be running an IRC network bouncer like psyBNC).Send email to consult@math.uic.edu right away explaining the cause of such an excessive upload to get the filter removed from your machine.

---

A: You need to create a file named .forward on tigger with the following contents:

username@machinename.domainname.edu
\tiggeruserid

Where tiggeruserid is your tigger userid and username@machinename.domainname.edu is replaced by the email address you want mail forwarded to.

A: Hold down the Meta key on your keyboard and move the window using the left mouse button. (Finding the Meta key: On Sun keyboards, the Meta key is marked with a solid diamond. On PC keyboards, the Meta key is marked with a Microsoft Windows logo. On Mac keyboards, the Meta key is marked with an Apple logo. If your keyboard has no Meta key, try the Alt key instead.) When the gray bar at the very bottom of the window comes into view, resize the window by dragging one of the corners of the gray bar. The problem is caused by switching from computers with higher resolution to computers with low resolution. Try to use smaller windows when using high resolution computers, or resize your windows when you finish a session on a high resolution computer. If you never use a computer with a high resolution, it is possible to change your xresources to accomodate the lower resolution. Send questions about this procedure to consult@math.uic.edu.

A: There are three reasons why this might happen.

1. Your web pages are readable only by you; nobody else has permission to view them. Fix this with the command:

   <chmod -R a+r ~/public_html/*

2. Your web pages are inside a folder that's usable only by you. Fix this with the command:

   chmod a+x ~/public_html/foldername

3. Your public_html directory is a real folder inside your home directory instead of a link to a folder on the web server. You might be able to fix this by doing the following:

   mv ~/public_html ~/public_html.bak
   ln -s /home/www/username/public_html ~/public_html
   cp -Rip ~/public_html.bak/* ~/public_html
   

   (Here you must replace username with your own mathid.)

---

A: Use ftp (Fetch on a macintosh.) From the new account, ftp to math.uic.edu using your username and password. (If you do this your password will not be encrypted. If this bothers you, please email consult@math.uic.edu for instructions on uploading to our anonymous ftp server.)

If your new account is on a unix machine, you may first connect to your math.uic.edu account via ssh and use the command:
tar -cvf myfiles.tar .
to pack up the contents of your directory, use binary mode to transport it by ftp, then unpack it using the command:
tar -xvf myfiles.tar
You should probably unpack in an empty directory to avoid overwriting any important files.

A: The emacs editor provides a mode for entering the ISO-latin-1 character set, which includes the alphabets of most western european languages. The accented letters are especially easy to deal with by using the command M-x iso-accents-mode. In this mode the accented characters can be entered by typing one of the ASCII characters ' ` " ^ ~ / followed by a normal letter. (To enter one of the special two-character sequences without getting an accented character type a space in the middle.) Some samples are shown in the table below. Type C-h apropos iso-accents-mode in emacs for more information.

type this	to get this
'e	é
`e	è
"u	ü
^o	ô
~c	ç
/o	ø
"s	ß
/a	å
/e	æ
~<	«
~>	»
~!	¡
~?	¿

The vim editor also supports the ISO-latin-1 character set. Type
:help digraphs
in vim for more information.

A: See our web page on the subject.

---

A:Unless the pages were printed, the counter doesn't increase (the pagecount is incremented from the value that is returned from the printer. The printer has a mechanical counter).

The number of pages you have printed is not updated immediately after the print job is over. Your pagecount is updated when someone else prints a job on the same printer after you.

---

A: Use the command chmod. To make private.file unreadable and unwritable by anyone else you can type chmod og-rwx private.file To learn more about chmod type man chmod

---

A: Some mail readers, like emacs and Netscape, collect mail from your mailbox and file it in some other location. This is what has probably happened to you. If you have used Netscape to read your mail recently, we have a web page devoted to this topic. If you use emacs, look for a file named RMAIL in your home directory -- that's where your mail is now.

A: Graduate Pedro Frietas provides two formats for thesis writing -- one paper saving and one University Approved -- on his web site. Aileen Gonzales has also made her thesis style documents available at ftp://ftp.math.uic.edu/pub/gonzales/uicthesi.

To conserve paper, please add the following lines near the top of your thesis.tex file until you are ready to print out your final draft:

%remove the following for your final version which must be double-spaced
\renewcommand{\baselinestretch}{1}

---

A: On the Sun computers, use (for example) dvi2pdf file.dvi. The output will be a file named file.pdf.

A: Read this note: Eudora configuration

---

A: Create a .forward file in your home directory on the machine you wish to forward mail from, e.g. tigger, containing the email address you wish mail forwarded to. But first, be sure that that address is not forwarding mail back to the first address! For example, if your email address was xxx@math.uic.edu, you would log on to tigger and type:

cd
echo "xxx@math.uic.edu" > .forward

---

A: You are probably using telnet and SKey to login to NWU. Good news: they're now running ssh on some machines, so you may be able to connect from the math department without your list of SKeys. Try connecting using ssh, as described on our secure connections web page. If that doesn't work, consult the sysadmin at NWU.

---

A: Most unix machines in the department have Maple installed. Type xmaple in a terminal window to start it.

The department does not own a copy of Mathematica.

If you want to use Matlab, you might first try using octave on the linux machines in Room 736. Octave is a free Matlab clone. It is compatible with the Matlab language, and has versions of most of the Matlab libraries, but there are some small differences that can cause it to be necessary to make a few changes to Matlab programs in order to get them to run under Octave.

The commercial version of Matlab is running on our new 4-processor Sun compute server, galois. You can ssh to galois from most of the department's computers and run Matlab. If you are running X windows, the ssh program will automatically take care of setting up the X server so the Matlab graphics will appear on the screen that you are using.

Netscape is free -- you get what you pay for. However, if you start Netscape with the address of a web page it will go to that web page first. Type netscape http://www.math.uic.edu in an xterm to start Netscape, or edit the preferences on the menu or icon which you use to start netscape.
