To add “virtual” users :

In /etc/proftpd/proftpd.conf:

DefaultRoot ~
AuthUserFile /etc/proftpd/ftpd.passwd
RequireValidShell off

Then restart proftpd: /etc/init.d/proftpd restart

Create users file:

vi /etc/proftpd/ftpd.passwd
username:HASH:1011:1011:MyUserName:/home/ftp/directory:/bin/true

You can also generate the user lines with the ftpasswd command, but I think it’s simpler to generate passwords with the command:

mkpasswd --hash=md5

Then paste the HASH in the passwd file.

Correct passwd file permissions:

chown proftpd /etc/proftpd/ftpd.passwd
chmod go-r /etc/proftpd/ftpd.passwd

And just test it to finish.
