Help on basic commands at working with SSH protocol

SSH access service is not provided at all price plans.

In some cases you can enable SSH access individually from Plesk control panel ("Installation" menu of the selected domain hosting).

Besides, the service can be enabled at a separate request from the contact e-mail to support@r01.ru address (agreement number and domain name under hosting service shall be indicated).

For SSH connection to the hosting server it is possible to use, e.g., PuTTY — a free telnet/ssh client.
