SSH-Login ohne Kennwort in 3 Schritten
2010-11-27
Schritt 1: Generierung des Schlüsselpaares
you@localhost:~$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/you/.ssh/id_rsa):
Created directory '/home/you/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/you/.ssh/id_rsa.
Your public key has been saved in /home/you/.ssh/id_rsa.pub.
The key fingerprint is:
27:e7:1f:0c:99:7d:3b:86:cb:39:91:55:5b:0d:e5:20 you@localhost
The key's randomart image is:
+--[ RSA 2048]----+
| E ooo|
| . o+|
| .+|
| + .. |
| S * .o. |
| = ooo . |
| . +.+ |
| o.= . |
| =. |
+-----------------+
Schritt 2: Erzeugung von ~/.ssh auf Remote Host (optional)
you@localhost:~$ ssh remote_user@remote.host 'mkdir -p .ssh'
Schritt 3: Öffentlichen Schlüssel publizieren
you@localhost:~$ cat ~/.ssh/id_rsa.pub | ssh remote_user@remote.host 'cat >> .ssh/authorized_keys'
