Put ssh-server in order to throw files into the necessary directories with Putty or FileZilla.
We have a network with an external (white) ip, a purchased domain (*****.ru), how to make sure that users from outside the address can access the site.
Please help point me in the right direction.

We set up the purchased domain on the DNS server - by IP (if you have bind on ubuntu server) or domain names (if on hosting). In the domain setting, make an A record on *****.ru specifying the IP of the server.
