comment How to completely password protect login into Ubuntu 12.10?
Also if you encrypt just the home directory, your passphrase is stored in an unencrypted portion of the hard disk; can not a software tool find it?!

comment How to completely password protect login into Ubuntu 12.10?
Thanks Stephen! I was reading about BIOS password; setting a password for Grub entries is not that straightforward! Is there a command line tool to do it automatically? If you encrypt your home directory, can someone mount the hard drive with a Live USB and install a keylogger, and steal your encryption password? I am not sure if there are keylogers for Ubuntu and if they capable of recording passphrase. Encrypting the WHOLE system is the ultimate solution !

@Kitsune. Thanks! My system is rather up to date, maybe I give encryption a try, see how it works!

Yes, I think it was BIOS. I understand that you can take the hard drive and access it from another machine (OS) and only encryption can protect you in this case. But I guess that's too much for the other person to do, specially for laptops. How do you set a BIOS password for grub entries?!

I know about encryption, but with current technology, it's still not there yet. Imagine you download stuff and read write files etc and to encrypt all this in real time slows down the system. At least for laptops !

I am also pretty sure that at University, we were once trying to get into a linux machine and there was absolutely no way to do it! When we tried Live USB boot or even a fresh installation the system would ask for admin password. How can I do this?

Thanks a lot for the information. I was just reading the man page for grub and apparently if you edit /etc/default/grub file and activate line RUB_DISABLE_RECOVERY="true", the recovery mode wont show up in boot. I did it and pressed ESC and left Shift keys, recovery mode is gone now.

Great simple answers to simple questions! Wish I had enough privileges to vote up! How much does VPN slow down the traffic? Like you may watch youtube during your 1 week conference, video chat with wife, etc; not sure if VPN gets annoying in such traffic.

Thanks a lot; this information is very useful! I have to go over the first part again! Website login passwords are in particular a great concern. If they get your passwords, they do not need further interception anymore!

Thanks a lot. Roaming charges get a lot if you travel often. Also nothing matches Ethernet in speed. But thanks for pointing out this; I check it out.
