TIDBITS On UNIX

Tid Bits for UNIX Users on a KU Server Korn Shell (ksh)
The UNIX server that support KU e-mail provides csh as the default shell. This shell has many good features, but, given my typing ability, I find the ksh, with it's command line editing capability (I use vi), to be more suitable to me. You can spawn and work in a ksh as follows.

add as the last line of your .cshrc file (in your home directory), the command, ksh ${HOME}/.profile
create a .profile file in your home directory and add the following lines to it:

export HISTFILE=${HOME}/.sh_history

# The next line can be changed from, vi, to emacs if you prefer that editor

export EDITOR=vi

export SHELL=ksh

exec ksh

After this is done, log off of the system and log in once again. After logging in to the e-mail server, type q, to excape to the UNIX shell, which will now be the ksh. You can now recall previously typed commands as well as edit them using the vi commands (or emacs).

X-windows
You can use the xwindows software on the UNIX machines directly from your PC. This requires some additional effort on your part. Proceed as follows:

1. On your UNIX account

Make a bin directory under your home directory.
Download the following Virtual Network Computing (VNC) files, and add them to your bin directory. To find out more about this VNC tool, go to http://www.uk.research.att.com/vnc/index.html

LICENCE.TXT LICENCE.TXT

Xvnc Xvnc

vncconnect vncconnect

vncpasswd vncpasswd

vncserver vncserver

vncviewer vncviewer

Then edit your .profile file in your home directory and add the following line

export PATH=$PATH:${HOME}/bin:/usr/local/SUNWspro/SC4.2/bin:/usr/X/bin:/usr/local/SUNWspro/bin

Save the changes to .profile.

dot your .profile, i.e., type ". .profile" (not typing the " characters). This executes your .profile and exports your new PATH environment variable.
execute the vncserver command. This will spawn a vncserver process. It will also ask you to set a new password for logging in to this vncserver process. Remember your password, as you will need it.

2. On your PC

Download (for windows2000) vncserver pc_vncviewer onto your PC. Unzip it (via winzip).
Put a shortcut to this viewer on your desktop.
Double click on the desktop shortcut to run the vncviewer on the PC.
When prompted for a system, type the name of the process that was spawned on the UNIX machine, when you typed vncserver on that system, e.g., pooh:1
When prompted for a password, enter the password that you set on the UNIX machine (see last temp of 1. above).
You should be in the xwindows environment at this point. You can open up additonal xwindows on the UNIX machine by typing

xterm &

at any time. You can copy and paste from one window to another and run workshop (a C/C++ software development environment), etc.
