Самым распространенным способом удаленного управления в unix/linux мире является протокол ssh.

Для подключения к свежеустановленному серверу или рабочей станции с debian 7 (впрочем, как и других версий) нужно установить сервер ssh, а для подключения к другим компьютерам — ssh клиент.

Устанавливаем ssh сервер

Воспользуемся широко распространенным и бесплатным пакетом openssh:

root@deb01: ~# apt-get install openssh-server

Устанавливаем ssh клиент

Уже упомянутый openssh содержит, так же, и отличный клиент ssh:

Как пользоваться клиентом ssh

Для подключения к другому компьютеру по протоколу ssh теперь достаточно указать пользователя, сервер и пароль для подключения:

root@deb01:~# ssh user@serv01
user@serv01's password:
