Randolph - any idea how it gets disabled? I'd think that would something that would default to on.

comment Using dpkg to install packages from a local directory
I do this for our product. I simply add a file to /etc/apt/sources.list.d. That way I don't have to modify the system installed file. It works great.

comment Looking for a USB Thumbdrive / Flash drive encryption solution (not TrueCrypt)
Just so you understand: It's not possible to do what you want and have the encrypted volume show up as a normal drive. As long as you are OK with using a special app to access stuff, you can do it.

comment How to set a Linux Ditribution to self-destruct (to wipe everything from the system partition) via a script
The problem is that once they see the VM destroy itself, they'll just get another copy off their USB stick, boot the VM from a live CD and start poking around until they find out what it does to kill itself. As long as you are comfortable with the fact that a sufficiently motivated user can get around it, then you're golden. Then all you have to do is to update the VM image before each class...

I'm not sure this is going to really further your goals. If they plan to steal the software, they are probably going to grab a copy of the VM during the course. They they'll be able to screw with it at their leisure. They can always boot the VM off of a live-cd in order to examine the thing to figure out what you did.

Well, if the user is logged in as a user with appropriate permissions, AND if they know what's going on, then they could, in theory, kill the 'dd' command, but not before it does a lot of damage (the partition tables are near the front of the disk, for instance).

comment How to tell if a laptop has been used of off the normal network
The worst of it is, if the users find out you're doing this, they'll change their behavior to make it look like they do go home with the laptops.

comment How to tell if a laptop has been used of off the normal network
I don't know the users in question, but if they are anything like me, then no, they won't. I shutdown and restart my laptop as infrequently as possible because the login scripts take about 10 minutes to run. At the least he'd have to look for suspend/resume and hibrenate/resume as well.

comment Connect monitor of a defective laptop to desktop PC
Define please 'dead' in this instance. Won't power up? HD trashed? Can you get to the bios? Boot from floppy/CD/USB? If it can run code to some degree you might do something with it.

Since the laptop in question is listed as 'dead', I'd bet this isn't going to work.

comment Will installing Linux wipe my restore partition?
If you are going to do this, I recommend using sysinternals sdelete with the -c option before taking the image. This will write zeros to all unused sectors on disk, making the final image much more compression friendly for long term storage.

comment Is email encryption practical enough?
@Mnementh: If you are going to have personal meetings, you might as well just use them for key exchange. No need for a keyserver, then. Keyservers are nice, but you end up having to trust something else, somehow, in order to use them. That's where I get nervous.

Actually, secure transmission isn't required, just initial secure key exchange. If you can exchange keys securely, AND we assume that the encryption algorithm has exploitable flaws, then it doesn't matter if the intervening networks are secure or not - only the recipient will be able to decrypt the message.

Signing e-mail is not the same as encrypting it. Signing solves the identity problem (who sent it), but it doesn't keep the contents secret.

comment How to test your backups against medium degeneration?
SMART results may not tell you as much as you'd like. Google labs did some testing - labs.google.com/papers/disk_failures.pdf and found that they got lots of failures with no SMART warning at all.

May I ask how you got to this state? Windows generally won't let you do this.

comment Why can I not combine two partitions into one from Disk Management?
Yuk. I just checked the Wikipedia entry. Apparently Symantec hasn't updated the thing in years, and it had crash problems with Vista formatted partitions. No mention of Win 7, but I'd bet that it's no good. Too bad, I bought a copy from PowerQuest years ago and it was rock solid at the time. Sad to see Symantec letting it go to bit rot.

Well, now we know. He needs to backup first anyway, but it's good to know. Can the latest PM work with Win 7 drives?

comment Why can I not combine two partitions into one from Disk Management?
Well, you don't really have any other options. I believe that there is no free tool that will combine live filesystems and leave the contents intact. I'm not even sure Partition Magic (a non-free tool) can do that. Combining two filesystems without losing any data along the way is pretty difficult to get exactly right. Even if there were a free solution, you'd need to back everything up first, because any bug could destroy all your data.
