If you just want the output that normally comes to /dev/console to come to your vt100: 1) Leave the prom alone, and enable a getty on the port your terminal is on. 2) Login on the terminal, do script /dev/null to get a pty. 3) Run a program which does a TIOCCONS ioctl on fd 0,1 or 2. This switches /dev/console to your pty. Start screen print mode on your terminal. 4) Never open a Consoletool in your window system. This isn't ideal, (doesn't work in single user, have to log in and start after reboot etc), but it is pretty easy, and should work. I've done something similar to get at kernel printfs remotely when using the "trapopen" code I posted a while back.

I should probably use that explicit Internet address in the From field when the original address ends in ".bitnet". --wnl ]]

The man page for cmdtool (under 4.0 at least) says that you can give it a program to run in the window, with a default of the SHELL variable or /usr/bin/sh. I've not tried it, but I would imagine you could set up a .sunview that would pipe that shell through tee, with the output going to a dedicated printer or perhaps even an lpd queue. It says "program" not "shell command line", so it might not like a |, so running a simple script with the necessary incantations should do it. Cmdtool also seems to let you save its text into a file, but that would require manual intervention and wouldn't help with crashes. None of this, of course, helps outside of suntools. Hacking your syslog.conf file will let you catch at least some of what you'd like to print. Or you could just give up these silly windowing systems, stick a DECwriter on there like G_d intended, and learn ed........ Anthony A.

Enclosed is a little utility I hacked up to do something similar. It is
run from our rc.local script:
consolelog /dev/ttya /usr/logs/`hostname`
and logs all console messages to the named files. If it is sent a SIGHUP
it will re-open all the files. This allows a sequence like
mv logfile logfile.old; kill -HUP pid
to trim the log. The filename "-" is recognised as stdout and is not
reopened with a SIGHUP.
This was based on "contool" by Chuck Musciano. (I have a similar feature
hacked into contool.) Many thanks!
Shar and enjoy!!
Greg.
