Netware Debugger Monitor keystrokes

Posted by Bob Jonkman on 25th July 2012

Photo of a Novell Netware screen

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

System Administrator Appreciation Day Dinner

Posted by Bob Jonkman on 10th July 2012

Pictures are up!

300 new servers? By next Tuesday? Sure, no problem!

System Administrators install servers

System Administrator Appreciation Day falls on 27 July this year, a global celebration of System Administrators around the world. To see what System Administrators do, have a look at some of the systems they have to administer.

After the KWLUG meeting in July, Becky asked me where System Administrator Appreciation Day is being held. “It’s a global event”, I said, but Becky was hoping for something a bit more local. So we decided to have a System Administrator Appreciation Day Dinner. What better way for System Administrators to celebrate than by treating ourselves to dinner?

If you can read this, thank a System Administrator

System Administrators maintain web sites

So, if you’re a System Administrator, married to one, or good friends come join us!

Friday, 27 July 2012 from 6:00pm to 9:00pm iCal
Egg Roll King Restaurant (map)
85 Courtland Avenue East 
Kitchener ON

Your computer ate all your files? I can fix that!

System Administrators make backups

If you’re planning on coming, let me know by e-mail or in the comments by Wednesday 25 July so that I can reserve enough seats and egg rolls for everyone.

–Bob & Becky
