Hey
Im not sure if this is the right list, but anyway, let me know if im wrong.
What im trying to do is, have a custom program run on a specific tty. Say like
ttyv4, or so. But I would like to do this without having to login to this ttyv.
So instead of being presented with a login option, I would like to be able to
switch to ttyv4, and have it show me the output of the program that is running
and using that terminal for output.
So exactly where about do you go about doing something like this? Is there
something already created to do this?
On a physically-secured machine I have this setup for ttyv1 in /etc/ttys:
ttyv1 "/usr/libexec/getty IPMonitor" cons25 on secure
and then in /etc/gettytab I have this entry for IPMonitor:
IPMonitor:\
:al=ipmonitor:tc=Pc:
Next, I have a special user named "ipmonitor" that is locked out (the
password field is set to *LOCKED* in master.passwd) but has a special
login script, like this:
ipmonitor:*LOCKED*:65499:65499::0:0:IP Monitor
Screen:/home/ipmonitor:/home/ipmonitor/bin/monitor.sh
Finally, the special login script for ipmonitor is this simple script:
#!/bin/sh
exec /usr/bin/systat -ip
I've also used vidcontrol with the -s option in a script like this to
grab the screen.
Hope this helps,
Guy
