Proftpd virtual users, home directory?

Question

linux

Please tell me how to restrict virtual users to only this directory (/var/www/site.ru)?
I create a virtual user, specify the user and group from www-data

ftpasswd --passwd --file=/etc/proftpd/ftpd.passwd --name=vuser1 --uid=33 --gid=33 --home=/var/www/site.ru --shell=/bin/false

Jupers can access ftp, but they have access to the very root of the file system, how to limit only home home=/var/www/site.ru

Answer 1

The keyword is chroot. In Proftpd it is enabled via the DefaultRoot option with a value of ~ (tilde).
