      RT @arunisaac IISc is asking students' for Aadhaar again. This time, it is for NAD (National Academic Depository) registration.

They expect people to enter their Aadhaar IDs in this public spreadsheet! Such […]

      I've been a SysAdmin for about 30 years, I've installed OSes from the days when you had to format a hard drive with debug G=C800:5, I've installed, destroyed, repaired and recovered Netware, Windows and Linux systems. But flashing a phone or tablet scares the willies out of me.

      Hi @EineBiene: The groups I created are all at http://sn.jonkman.ca/groups/ There are currently no plans to move them; my https://gs.jonkman.ca/ instance is too flakey right now -- I can't subscribe to my own groups, for example.

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

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

Charming comment spam

Posted by Bob Jonkman on 6th July 2012

Smoke curls up

Genie in the bottle

This blog may not have many readers who leave comments, but it sure does have a lot of commenters who leave spam! Still, I make sure to go through the list of pending comments in case there’s a real one in there. Today, I came across one comment that was obviously spam, but charming with its fractured English and a punch line I hadn’t heard before:

AftequeAlew:
A houseman was walking on the beach harmonious day and he bring about a bottle half buried in the sand. He irrefutable to provide it. Stomach was a genie. The genie said,” I resolve agree to you three wishes and three wishes only.” The gentleman prospect there his beginning demand and decided, “I think I be deficient in 1 million dollars transferred to a Swiss bank account. POOF! Next he wished after a Ferrari red in color. POOF! There was the transport sitting in van of him. He asked in search his settled hanker, ” I wish I was irresistible to women.” POOF! He turned into a box of chocolates.
