! 16: \begin{enumerate}
! 17: \item Log in as the super-user (root).
! 18: \item Change Directory to /usr/sbin
! 19: \item Enter {\tt adduser}
! 20:
! 21: \item A prompt will appear. Follow prompt to enter information about the user. The example
! 22: used here is for the user name {\bf teacher}
! 23: in the group {\bf cai}.
! 24: \begin{enumerate}
! 25: \item Enter login name: {\tt teacher}
! 26: \item Enter a UID: For most cases, using the default UID is preferable. Just
! 27: enter $<$return$>$
! 28: \item Enter a full name for user: {\tt Instructor for course}
! 29: \item Enter a login group for user: {\tt cai}
! 30: \item Enter another group that user should be a member of. \\
! 31: ($<$Return$>$ only if none): Just enter $<$return$>$
! 32: \item Enter a parent directory for user:{\tt /usr/user3}
! 33: \item Enter a login shell for user:{\tt /bin/csh}
! 34: \item Do you wish to edit the auth file entry for this user?
! 35: {\tt n}
! 36: \item New password: {\tt password} \\
! 37: {\bf NOTE:} The password
! 38: will not be echoed to the screen.
! 39: \item Retype new password: {\tt password}
! 40: \end{enumerate}
! 41: \item The compressed files for the \capa\ system version 4.6 are to be placed in the
! 42: directory \\
! 43: {\tt /usr/user3/teacher/DIST46}.
! 44:
! 45: \item Expand these compressed files by typing {\tt uncompress DIST46.tar.Z}
! 46:
! 47: \item Untar the directories by typing {\tt tar -xvvf DIST46.tar}
! 48: The DIST46 directory will then contain the following items:

! 329: \item Some notes:
! 330: \begin{enumerate}
! 331: \item The \LaTeX{} and dvi programs must be properly installed on the host
! 332: machine in order for {\tt quizzer} to format the problem sets.
! 333: See your system administrator for help in installing these programs.
! 334: \item For a broad range of terminal emulators to be able to access the
! 335: system\footnote{by G. Perkins, MSU P/A Dept.}, it is necessary to modify the
! 336: {\tt /etc/termcap} file to accommodate the appropriate vt100 \label{vtEmul}
! 337: terminal attributes, including handling non-standard nomenclature used by
! 338: terminal emulation programs on Macs and PCs. A notable example is the widely
! 339: used {\it tn} program that is part of FTP Software, Inc.'s PC/TCP package. This
! 340: program negotiates its terminal type with the host computer using the prefix
! 341: {\tt dec-}
! 342: for the {\tt vt} family of terminals ({\it e.g.,} it requests terminal type
! 343: {\tt dec-vt100} instead of {\tt vt100}). This prefix, if unknown to the Unix
! 344: host, may cause the negotiation to result in an incorrect terminal type or to
! 345: fail completely. \\
! 346: The line in the standard {\tt /etc/termcap} file that reads\\ \\
! 347: {\tt d0|vt100|vt100-am|vt100am|dec vt100:$\backslash$ } \\ \\
! 348: should be edited to read:\\ \\
! 349: {\tt d0|vt100|vt100-am|vt100am|dec-vt100|dec vt100:$\backslash$ } \\ \\
! 350: thereby establishing {\tt dec-vt100} as an official synonym for {\tt vt100}.
! 351: Note that the ``{\tt dec-vt100}'' entry is different from the ``{\tt dec vt100}''
! 352: entry. We advise adding the new alias rather than changing the existing alias
! 353: and possibly causing other problems.
! 354: A similar change can be made on other operating systems which use the
! 355: {\tt /etc/termcap} method of terminal definition. Unix systems using the
! 356: {\it terminfo} program instead will support similar minor changes to the
! 357: appropriate file or files in the {\tt /usr/lib/terminfo} directory tree (consult

! 442: can be placed under the teacher account, just as was done for nsc111f8 above, i.e.,
! 443: phy232f8, cem152f8, xph232f8, etc.
! 444: \item {\bf logout} as root.
