passwd

to change your password.

The program prompts for the old password and then for the new one. You must supply both, and the new password must be typed twice to forestall mistakes.

How do I check my disk quota?
Use the UNIX command

quota -v

to check your disk quota.

/archive is a special filesystem that has been created by the NSCEE. as the location of choice for very large files (> 250MB) that are to be archived from disk to a tape storage medium via the Data Migration Facility. The current size of the /archive filesystem is:

/archive ~5,829,120 .5K blocks (~2.98GB)

/archive is NFS-mounted on all NSCEE machines and serves as a file 'sink' for NSCEE users. /archive contains directory hierarchies that mirror the NSCEE's user filesystem hierarchies below the filesystem name.

To simplify use of the /archive filesystem, all users have had a symbolic link named 'archive' placed in their home directories. This link points to their corresponding directory in the /archive filesystem and can be used like any other directory.

A complete example of the preferred use of the /usr/tmp and /archive filesystems follows (note: with the exception noted, this example is valid in both bourne and c shells. Comments are placed to the right of the '#')

% setenv MYTMPDIR `tmpdir /usr/tmp`  # create a temporary directory
(bourne shell users use:  MYTMPDIR=`tmpdir/usr/tmp`; export MYTMPDIR)

% cp myprog $MYTMPDIR/myprog         # copy any necessary files to it

% cd $MYTMPDIR                       # change your working directory

% myprog > bigfile                   # execute your program

% mv bigfile $HOME/archive/bigfile   # mv any big files to be migrated

% cd $HOME/archive                   # change your working directory

% dmput bigfile                      # migrate your big file

chfn is used to change information about users. This information is used by the finger program, among others. It consists of the user's "real life" name, office room number, office phone number, and home phone number. chfn prompts the user for each field. Included in the prompt is a default value, which is enclosed between brackets. The default value is accepted simply by typing [RETURN] or [ENTER]. To enter a blank field, type the word none. Below is a sample run:

          Name [John Doe II]:
          Room number (Exs: 18A or 17B) []: 22C
          Office Phone (Ex: 223) []:  227
          Home Phone (Ex: 6610379) [5771546]:  none

chfn allows phone numbers to be entered with or without hyphens.

It is a good idea to run finger after running chfn to make sure everything is the way you want it.

If you are accessing the NSCEE by dialing into any of the modems that we provide, one method for transferring files is kermit. We have many of standard file transfer methods available: Kermit, Zmodem, Xmodem, and Ymodem. NSCEE recommends making a .kermrc file in your home directory, with the following contents:

set send packet-length 1024
set receive packet-length 913
set buffers 8192 8192
set window 4
set block-check 3
set file type binary

This kermit configuration yields excellent performance for both uploads and downloads to the systems.

• SLIP (Serial Line Internet Protocol) is an Internet connection that allows a computer to use Internet protocols to become a part of the Internet. Requires a modem, a standard telephone line and a NSCEE account.
• PPP (Point to Point Protocol) is an Internet connection that allows a computer to use Internet protocols to become a part of the Internet. Requires a modem, a standard telephone line and a NSCEE account.

For users who desire direct IP access, NSCEE will provide Slip and PPP service. Call 1-702-895-4153 and ask for Dialup Slip and PPP access.

For users who desire direct IP access, NSCEE will provide Slip and PPP service. Call 1-702-895-4153 and ask for Dialup Slip and PPP access.

• Non-Graphical VT100 interface: The only software necessary is a terminal emulation package that supports VT100 or VT102 emulation. Nearly any dialup DOS, Windows or MacIntosh communication software will do this. Examples of available software include, but are not limited to:
  • Procomm and Procomm Plus for DOS or Windows
  • MS-Kermit for DOS or Windows
  • Terminal programs available in Windows 3.1 and Windows 95

• Graphical interface: Examples of available software include, but are not limited to:
  • Web Browers such as Netscape and Mosaic
  • E-Mail tools such as Eudora Light
  • NCSA Telnet for DOS or MacIntosh platforms
  • Xterm programs on UNIX systems

Man pages are divided up into sections such as name, synopsis, description, bugs, and "see also". There may also be other sections involved. A man page may be as short as one screen of text, or up to 20 screens of text. Pay attention to the description of the program and necessary command line switches for the program. Don't be discouraged if a man page is confusing, or seems overly complex. Usually just a brief skimming of the page is enough to get you started with a program or utility. You can then use the remainder of the information in the man page as a reference. To quit out of a man page, simply hit q.

• mv
  Moves a file from one name to another. The old file is completely replaced with the new file.
  Syntax: mv oldfile.html newfile.html
• cp
  Copies a file to another name. Both copies of the file still exist.
  Syntax: cp oldfile.html newfile.html
• rm
  Removes a file from your directory completely. Only us this command if you are ABSOLUTELY certain you will no longer need the file!
  Syntax: rm filename.html
• cd
  Used to change to another directory. Syntax for lower level directory: cd directoryname
  Syntax for higher level directory: cd ../upperdirectory
  Note: It is helpful to view your directory structure as a directory tree.
• rmdir
  Removes a directory. WARNING: Do not do this unless you are absolutely certain you don't want any of the contents of this directory!
  Syntax: rmdir directoryname
• mkdir
  Makes a new directory.
  Syntax: mkdir newdirectory
• ls
  Lists the contents of your current directory.
  Syntax: ls
• more
  More is a program allows examination of a continuous text one screenful at a time on a soft-copy terminal. It normally pauses after each screenful, printing "--More--" at the bottom of the screen. If the user then hits a carriage return, one more line is displayed. If the user hits a space, another screenful is displayed.

• MH
  MH stands for Mail Handler. This mailer fully interacts with the command line and is a complex mailer that involves the knowledge of many separate UNIX commands in order to use it. Not recommended for the novice user.
  Syntax: Read the man page on MH for all necessary information.
• Pine
  Probably the best mailer for beginners. Pine prompts with an interactive screen so that it's difficult to get lost or confused within the mailer.
  Syntax to read and send mail: pine
• Eudora Light
  Probably the best mailer for the Slip and PPP crowd.

• tin
  A relatively simple news reader. Uses menus and makes navigation through Usenet rather simple.
• trn
  A threaded newsreader which is faster than tin, but is slightly more complex.

• pico
  Pico is likely the easiest editor online for novice users. Man pages for this editor are online, and prompts for quitting and various editor options are always left onscreen for easy reference.
• vi
  vi ( pronouced "V eye" ) is based on an old editor, ex. It's slightly more complex than pico. Be certain to read the man page on this editor, and remember the general rule of thumb for VI: When in doubt, hit escape.
• Emacs
  Emacs is a very powerful editor that is designed for use by advanced users. If you want to give emacs a try, check out the man page for this program before you start.
