Post subject:  root password issue

I have an eleven character password. I noticed that if I only type in 8 of the characters, it allows me to login over ssh. Not sure if this is by design, a knoppmyth, or ssh issue. Anyone got a clue what's going on?

ssh encrypts only the first 8 characters of your password. It simply ignores the rest.

It's an ssh thing, not Knoppmyth

The passwords for root and first user are encrypted using DES in /usr/local/bin/KnoppMyth-install with the htpasswd command.

DES encrypted passwords are truncated to 8 characters.

Browse /etc/shadow and you will see root: followed by 13 random characters.
For mythtv and any user that has changed their password you will see mythtv:$1$ followed by more than 13 random characters.

Change your password with passwd command and it should be encrypted with MD5 and more than 8 characters will be honored.
