I had a room mate that put a livecd in my desktop and looked around on my machine. I caught him in the act and threw him out.

I haven't had a room mate for a while now and so as to avoid the livecd issue again I encrypted the hard drive, the machine is running centos 6.3.

Is there anyway that I can avoid typing the password in each time if I have usb key in the machine to feed the password to the system?

Additional question.

Is there anything you can suggest to solve the problem I have ? Thanks

Your question is off topic for Serverfault because it doesn't appear to relate to servers/networking or desktop infrastructure in a professional environment. It may be on topic for Superuser but please search their site for similar questions that may already have the answer you're looking for. – Iain Oct 26 '12 at 8:24

Sorry, RHEL (and by extension CentOS) does not yet support using key material on a USB drive to unlock the boot drive.

Have you tried a YubiKey?

I take no credit for this, having seen it at SuperUser, but have it on good authority that it works. I'm ordering one for my Truecrypt-encrypted system partitions at the moment.
