      When I was a young pup, just started my first job. Woke up at 4:30 one day, panicked, "I've slept through the whole day, I'll get fired!!" It was 4:30am, of course. Don't recall if I got back to sleep or not.

      RT @lnxw48a1 I woke up around 02:45, thinking it was 07:45. Before 03:00, I realized it wasn’t time to get up. I still really feel the lack of #sleep 💤.

      "A Supreme Court that doesn't give a damn what the public wants ... is exactly what a Supreme Court is for, actually." True enough. But elected representatives in government *are* supposed to do what people want, that's why they get elected. If they had fulfilled their obligations to actually represent the citizens' wants then the […]

      RT @clacke People, not all people but most people, are angry about the wrong thing. I agree that Roe v Wade being canceled is a bad outcome. I agree that women should have the right to their bodies, but here's my possibly unpopular take: A Supreme Court that doesn't give a damn what the public […]

      It's the middle of May, I'm sitting outside in 28C weather, just 100km west of Toronto, and the Leafs are *still* playing hockey?

      RT @guizzy @vriska I would wait before celebrating just yet. Never underestimate the Leafs ability to snatch defeat from the jaws of victory.

      It seems the state-of-the-art for autonomous vehicles is worse than I thought. Still, with the number of bad drivers on the road now, replacing them with bad robocars is still likely to be an improvement.

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
