1. Генерируем пару ключей для станции с которой будем ходить на другую станцию:
sergio@local-host$ ssh-keygen
2. Публичный ключ нужно снести в файл ~/.ssh/authorized_keys на станции-пациенте. Легче всего сделать воспользовавшись спец. утилитой ssh-copy-id:Generating public/private rsa key pair. Enter file in which to save the key (/home/sergio/.ssh/id_rsa):[Enter key] Enter passphrase (empty for no passphrase): [Press enter key] Enter same passphrase again: [Pess enter key] Your identification has been saved in /home/sergio/.ssh/id_rsa. Your public key has been saved in /home/sergio/.ssh/id_rsa.pub. The key fingerprint is: 33:b3:fe:af:95:95:18:11:31:d5:de:96:2f:f2:35:f9 sergio@local-host
sergio@local-host$ ssh-copy-id -i ~/.ssh/id_rsa.pub [remote-user@]remote-host
sergio@remote-host's password:
Now try logging into the machine, with "ssh 'remote-host'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
