Anti-theft Features

Hey I was wondering, are there any anti-theft featuers for Linux? Like I know that there are some software types out there for windows that let you trace where your computer is if stolen, like a GPS or Lo Jack. Also I know that some computers have encrypted hard drives or whatever. I once heard, not sure if it's true, but there are some systems that can wipe or encrypt a hard drive if a theft occurs. How it works, I don't know, may just be a rumor. Anyway, there are probably a ton of possibilities for Anti-Theft on a software side for Windows, I was wondering what was out for Linux

I am thinking of installing that system they used in Live Free or Die Hard. That exploding PC looks like it would take care of any security issues one might have.

If i stole your computer ( not that i would steal), but I would open it and examine the system so your security just failed.

i have read that if you do not encrept your hard disk, its very easy to boot to a live cd and change the passwords and then the entire security is compermised :-( BTW:is there some hope for running lojack via wine in suse boot scripts i got it as part of my laptops package, and its just going to waste.

OKay, so what's the deal with encryption? Like i understand that it encrypt the hard drive and what not, that part I get, what I don't get is, how does it work when you want to boot into the hard drive? are you asked to provide a key at boot or what? I know that when you have like an encrypted wireless signal, or encrypted file with mcrypt, you have to use a key to unencrypt it, well if you boot into an encrypted hard drive, how would the computer boot? Maybe I am just asking a dumb question, oh well. Thanks.

you are asked for the key before it boots AFAIK

Kewl, so do you type in the keep likeas if it were a password or is it like a gnupg style key where the key is like a file and you have to have it on like a jump drive or something at boot? Just wondering if anyone has tried this. Maybe I just need to either open a new post or try to find an old one, who knows.

I can point you to 2 approaches but not Suse specific there should be similarities though. I got a feeling Suse won't use LUKS though by default would take someone who's done this to confirm...

Now I have looked for more specific tut but couldn't find one there is one at opensuse but it seems a little dated.

I regards to lojack seeing stuff that if bios enabled that it will ring out before the OS, /. article someone mentioned using it for linux based. Seen other poormans version of using dyndns and updating the dns register with a cron job.

Though TBH if lojack is bios and onboard enabled this seems the only way that's nearly foolproof but I suspect there maybe a way.

You only have to make sure its not network enabled then it can't ring home, then you have all the time in the world to work around it.

Edit
Missed it http://en.opensuse.org/Encrypted_Root_File...with_SUSE_HOWTO

I am thinking of creating a poll to see percentage of those with encrypted root partition/files system. Yes?

SOunds like a good idea, see if it works or not.
