how do you crack linux passwords

[hexadecimal]

thanx il give that a shot

will going into runlevel 1 bypass the password authentication??

[MrLinus]

On some systems, yes. Single user mode or Runlevel 1 often means that it logs in as root with no password. Many systems have put in the LILO fix or used Grub, asking for a password to going to single user mode. IIRC, single user mode was a "if your forgot your root pass or had super serious issue" kind of mode.

[edit]

Take a look at The_Jinx's post on Page 2 of this thread. That gives a prime example of how to do this from a lilo prompt.

any ways i wanted to crack my password on a slackware machine, i already tried jack the ripper, and probably will try Crack. but are there other ways to crack linux passwords.
