Just happened to have forgotten a password for one of my user accounts on my workstation and remembered a handy little thing one can do to reset a pass.

If you have root access, one can simply regenerate the MD5 hash with:

# openssl passwd -1 -salt mysalt
Password:
$1$mysalt$JyKGOJR1343sJ7N91hXVI/
#

# ftp localhost
Connected to localhost (127.0.0.1).
220 Welcome to the Crazy Town .  If you are not an authorized user, please logout now!
Name (localhost:root): tom
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> quit
221 Goodbye.
#

and replace the existing hash string in proftpd or any other service with what ever is entered as a pass above.  This should help to reset your pass.

Cheers!
