Windows
Local connection on a machine running Windows can be established by any user who has the "Log on locally" user right on the machine.
Linux
Establishing a local connection on a machine running Linux, and managing such machine, requires the root privileges on it.
To establish a local connection as the root user
/usr/sbin/acronis_console
Otherwise, run the following command:
su -c /usr/sbin/acronis_console
To allow a non-root user to start the console
Caution: As a result of this procedure, the non-root user will not only be allowed to start the console with the root privileges, but also may be able to perform other actions as the root user.
To establish a local connection as a non-root user
sudo /usr/sbin/acronis_console
