81.0. "DECstation Management ?" by PRSSUD::BRZOSKA () Wed Jun 09 1993 18:10

    Hi,
    I would like to know how to manage remote DECstations with Console
    Manager. How can I achieve to send the console display to a tty
    connected to a DECserver and to remain able to view the console events
    on the "xcons" window of my DECstation ?
    
    Thanks for any idea.

	Dominique, I am afraid some DECstations are not manageable. If the box is a MIPS RISC DECstation i.e. a DECstation 5000 or 2/3100 series machine a feature of the X-server in ULTRIX does not allow you to redirect the console away from the graphic device or the X-Server crashes. We asked ULTRIX engineering to investigate this, but they did not really want to know. we did not design it to do that they said!! This restriction is documented in the SPD/SSA. On an ALPHA box running OSF/1 the X-Server will start correctly. What you get is messages sent to /dev/console are solicited to the console mgr system, but messages relevant to the user session i.e. the Application started and application error messages appear in the xcons box. Cheers SImon...

81.3	What about just booting/halting?	CERN::BOTHNER	Tor Bothner (CERN account consultant)	`Fri Jun 18 1993 13:22`	11
	Is it possible to controll a DECstation from the serial port, whithout having all the console messages sent to it? I.e. using the serial port only for booting the machine, and having the single-user interaction go through the serial port also? This way at least we'd get some of the functionality, i.e. not having to to the station when doing special, single-user systems work. possible??? --tor
81.4	A hack on the DS5000/200	OPG::SIMON		`Fri Jun 18 1993 14:27`	17
	Tor, I did manage something like what you are asking for on a DECstation 5000/200 system whilst testing earlier this yesr. It was not a perfect solution, but it fooled the X-Server and I did manage to be able to boot the system via CM. It was done using the console and osconsole environment variables at the >> prompt. As far as I can remember the osconsole variable is what is read by the ttdriver initialisation nd the console variavle is read by the hardware. Unfortunatly the osconsole variable is set from the console variable at powerup time or when the console subsystem is reset/initialised. Thi smeans that the person booting the machine has to set this variable each time before rebooting the system or the dreaded X-Server no start will occur. If you want I can try to get exactly what I did to get this to work for you. Cheers SImon...
