there’s no such thing as 100% not making a typo… everyone does it.

passwd not password

Besides, if you physically lock the computer inside a cabinet and turn off recovery and password Grub like above, you’re all set. If you have the computer sitting in front of you and can open it, then no BIOS password in the world will save you. If you can’t open it, but you can boot off a CD or log into an administrator account… Same thing. If someone discovers a backdoor in some service you’re running that allows admin access, well ditto. Encryption works even if someone gets smart and uses a boot CD or one of those external hard drive adapters on a second PC. Why else would there be RIPA laws in the UK?

and i hav question:
if i have one user so password for sudo is the same so if some one changes user password then sudo password also changes? or on installation for both users i got same password?

root@(none):/# password remco
send-mail: fatal: could not find any active network interfaces
Can’t send mail: sendmail process failed with error code 75
root@(none):/# _

Any help would be appreciated!
