Changing your mac address to something that doesn't look suspicious is one of the ways that you'd do it. You wouldn't want to change it to 00:11:22:33:44:55 because that'd stand out too much. Most home users, and corporate for that matter, don't keep track of mac addresses in their possession.

The only other way that you'd be able to locate it is if the system had some kind of dynamic DNS software like dyndns. When the system comes back online, the domain name that's associated with the account will get updated with the new public address and then you can track it back to a general location.

Wow! Thanks everyone for the awesome replies! I'll definitely look into it!

Awesome! Your site is the one that I linked to in my business proposal to have the class covered. I sent it to my boss' manager so he could see the reviews since it's not a "well known" cert.

Thanks hayabusa. I've read a lot of your other posts on here 

I read a comparison on this site (I'll have to find a link) that said eLearn's offering was more of a point and click course whereas OSCP was more CLI driven. Is that true? Any thoughts on that?

I'm interested in the OSCP class, but I have a concern about my current abilities. I've done pen tests for the company that I work for now, and I understand the basics of Metasploit, nmap, nessus, etc., but I've been reading comparisons between this course and eLearnSecurity's course. eLearnSecurity states that their course is designed for 0 - 3 years of experience and it seems to be the recommended before doing OSCP. I don't pen test on a daily basis, so I don't know how much relevant and practical experience in "years" that I really do have.

I don't know ASM (I'm reading up on it now), I have the basics of Python (written a few scripts from scratch), I don't know Ruby, and I know a little C/C++ but have never written an exploit. I've used BT off and on since BT3, but nothing major.

I guess I need to know if I'm a good candidate for the course. I don't want to get in over my head.
