OK, so no attachments, no contribution....
well....... OK then but you've got to handle the second CRT yourself:
How to set up Linux to start up a DM without logging in
Caution: This procedure will boot the box and run the DM under the root account
!!
Assumption: The procedure to use Linux to view remote DM's has been successful.
1) Boot the Linux machine and login as root.
2) Create the following scripts in /usr/scripts and make sure they are
executable:
Script 1:
#!/bin/sh
#
# startopenwin
#
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/openwin/bin
LD_LIBRARY_PATH=/usr/openwin/lib
OPENWINHOME=/usr/openwin
BASH_ENV=$HOME/.bashrc
USERNAME=""
export USERNAME BASH_ENV PATH LD_LIBRARY_PATH OPENWINHOME
openwin
Script 2:
#!/bin/sh
#
# stopX.sh
#
# Change to run level 3 to stop respawning of X
telinit 3
# Check to make sure a remote DM is not running
dmpid=`ps x |grep -e '/usr/X11R6/bin/xterm -T Remote IA' |grep -v grep |awk '{pr
int $1}'`
if [ $dmpid ]
then
kill -TERM $dmpid
fi
# Get the PID of the Xwrapper and olwm
wrappid=`ps x |grep /usr/X11R6/bin/Xwrapper |grep -v grep |awk '{print $1}'`
olwmpid=`ps x |grep /usr/openwin/bin/olwm |grep -v grep |awk '{print $1}'`
# Send a kill signal
kill -TERM $olwmpid $wrappid
3) Open /etc/inittab and make the following modifications:
1. Change the line reading 'id:3:initdefault' to 'id:5:initdefault'.
2. Comment out the line reading 'x:5:respawn:/usr/bin/X11/xdm \nodaemon'.
3. Add the following two lines
# Try starting openwin in runlevel 5
x:5:respawn:/usr/scripts/startopenwin
4) Edit /usr/openwin/lib/openwin-menu and comment out all items except the
Foxboro DM option. You may want to leave access to the 'Shells' menu until you
are sure this works properly.
5) Create the following .xinitrc file in / and make sure it is executable.
/usr/X11R6/bin/xset +fp /usr/fox/wp/fonts
/usr/X11R6/bin/xset fp rehash
/usr/X11R6/bin/xhost +
/usr/scripts/operate.fox &
/usr/openwin/bin/olwm -f
Note: After this procedure the only access to the box will be through a remote
telnet or rlogin session ... so ensure you are connected to a network prior to
making the above changes.
To stop the X window environment you need to telnet to the Linux box and run
the /usr/scripts/stopX.sh script as root. This script will change the run
level to 3, stop the DM (if running) and exit the X windowing system. A login
prompt can be used at the box after hitting the 'Return' key. Logging in as
root in run level 3 will not start the X windowing system therefore allowing
local prompt adminstration / shutdown.
