      RT @lnxw48a1 @geniusmusing Yeah. :-( I think the #blockwars folks may have indirectly caused this. There are people who file complaints against client apps that don’t build in blocklists against specific servers whose moderation policies they dislike. I think that #Matrix / #Element competes with one or more Google-owned chat-type services. Since they gatekeep the […]

      And I can't figure out how to connect to a particular server. The #Patchwork #SSB client I'm using has a "+ Join Server" field, but it requires an invitation code. Which I can't generate unless I have a pub server. Which I can't join until I have an invitation code... Sigh. #SSB: Concept: A+ ; […]

      I was on #SSB Secure Scuttlebutt for a while (attended an #SSB seminar at last year's LibrePlanet conference), but the application was so resource intense that my laptop couldn't keep up. And, there wasn't the network effect I needed to make it useful. While there are probably interesting people to converse with, I have no […]

      Oh, hang on. It's @joeyh who reveals the inadequacy of #journalism. Not the article author, @Jonemo@twitter.com #ReadingComprehension

      @lnxw48a1 writes "In this post, Joey H. accidentally reveals a major reason why #news_media / #journalism is so bad today." This didn't leap out at me. Is it because good, in-depth reporting requires A LOT of research and hard work, and that modern journalism is adequately rewarded by re-Tweeted sound bites?

      That was much better than I expected it to be. Covers the spectrum of opinions of several #ITSec professionals, and does not strike an alarmist note. Sadly, somewhat devoid of practical advice, tho. https://www.hipaajournal.com/hipaa-password-requirements/

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
