      Don't worry about it. I know that's not really helpful advice, but I've had experiences like this too. I think of it as "the wheels falling off". I suspect everyone has these times, but most people won't admit it. An uplifting aphorism I heard in a movie: "It will all be alright in the end. […]

      RT @nev i'm well aware canada's healthcare system is vastly inadequate, but just imagine if the housing system were anywhere near what the healthcare system was like. for-profit housing should be as obscene as for-profit healthcare. flipping houses should be seen as as unethical as hiking up insulin prices.

Netware Debugger Monitor keystrokes

Posted by Bob Jonkman on 25th July 2012

Novell Netware 6.5

I dig out my notebook with the Netware Debugger Monitor instructions and keystrokes whenever I’m called in to work on a new (to me) Novell Netware server. Typically, there’s some kind of problem that needs more SysAdmin powers than those available through the ordinary Netware console screens, and the Netware Debugger Monitor is what gives a Netware System Administrator his superpowers. Sometimes it’s even possible to regain control of a hung server by using the Debugger Monitor. Thought I’d share:

Swap Screens
ALT+ESC
List of screens
CTRL+ESC
Alternate console
CTRL+SHIFT+ALT+ESC
Shutdown prompt or the “Hung Console Menu”
CTRL+ALT+ESC
Entering the Netware Debugger Monitor
LSHIFT+RSHIFT+ALT+ESC
