Kerberos Tutorial

HI all,

I’ve just been writing a few notes for myself again so I thought I’d put them up for you to have a look at. The notes are on the Kerberos authentication process that takes place when a computer and or user logs onto the system.

 

As always please feel free to comment.

Managing Basic Disks

Hi all,

 

I’ve finally got around to typing up another quick tutorial, this time on basic disk management (mostly extending partitions from the command line). This is only a very short tutorial so is not ment to be extensive in any way.

Shutdown revisited

1


After a brief write up the other day I thought I would expand abit on the shutdown command and what i’ve been using it for.

The shutdown command allows you to “imaginativly” shutdown the computer from a Dos command. Common switches include -s for shutdown -r for reboot -f to force it to shutdown incase you have a stubborn app still loaded, and -t xx for time in seconds until shutdown. Also you can specific a -m COMPUTERNAME to specify a remote computer you want this to run on.

So a few examples of the command would start out and simply

SHUTDOWN -S

This would start a countdown of 30 seconds (whilst displaying a warning message) and would start the shutdown proceedure imediatly after the time has elapsed.

SHUTDOWN -S -T 10

This would do the same as above but start the timer at 10 seconds

SHUTDOWN -R -M \\HOMEPC

This would make the remote computer HOMEPC restart after the 30 second countdown.

IMPORTANT: at any point in the countdown you can type SHUTDOWN -A to abort the shutdown.

So I’ve used it at work this week as part of a scheduled task for a users pc. I was running a few diags on the machine and also doing a defrag, as I didnt want to sit there and watch it I started the scheduled task wizard and pointed it to the shutdown file located in %winddir%\system32 and then added the switches to it. Then it was just a case of following the wizard to get the machine to power itself off a 9pm. User didnt say anything the next morning so i assume it all went according to plan.
