How to record a signal sent over a computer network
19 replies, posted
My college uses Deep freeze for it's computers. But every Sunday night at 11:00 PM all the computers go into maintenance mode, and unlock themselves, allowing everyone to do pretty much whatever they want. I want to know if it is possible to record whatever signal is being sent over the network that tells the computer to unlock, so that I can use it at any time.

It's not a signal, deep freeze holds a schedule file internally that knows when to unlock.
Is it possible to edit this file? I'm guessing not...
Nope.
You can attempt to hack into a computer's bios and change the time.
I don't think it's too hard to change system time in BIOS.
And if it is password protected?

Which I have no doubts that it is.

If there's a BIOS pass just pull the cmos battery for a minute, usually works.

You can flash it if it's password protected.

For most of the new computers, the password isn't stored on the same EEPROM as the BIOS. Yes, lots of motherboards stores the BIOS password encrypted on non-volatile memory. Flashing the BIOS wouldn't do much.
Besides, I doubt you can even use any flash utilities, since the campus's computer administrators are probably not dumb enough to give you admin privileges, and usually sets HDD or network boot as the primary boot source.

On a computer at school?
Right.

actually, they aren't. I can access BIOS whenever I want. unfortunately the computer is synced to the Government time website... and I don't know if it will update at regular intervals or as soon as it logs on... it automatically logs out of maintenance mode at a certain time, so if it does update to the true time, this would be pointless.

Right.[/QUOTE]
I've done it.
Our computers at school are deepfreeze'd too. It sucks, but they all give us networked drive to hold our crap in.

What aren't? I've mentioned several things in my post

Password'd.
The really only real way around Deep Freeze is getting the password stored in the install file with the configurator or the Enterprise Console program (I've done both :v:)

They aren't set-up to network boot or use a password. The bios is unprotected.

And how praytell would you have done that?

In that case, it should make your life easier (And the administrators must be quite dumb)
All computers on our campus have the BIOS pw protected.
