SSH без пароля

SSH без пароля / SSH without password

Привожу пример для root, но под этим пользователем лучше не работать.


[root@pviz pviz]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
b5:ad:a3:50:4b:f9:37:b1:df:bd:6b:95:47:fa:8e:f3 root@pviz
The key's randomart image is:
+--[ RSA 2048]----+
