3PAR InForm CLI Administrator’s Manual InForm OS Version 2.3.1
In the previous example, user user1 logs into InServ system system1 and creates user
user3 with the password testpw3.
2 Create a key pair using the ssh–keygen utility. Both
rsa and dsa key formats are supported
by the InServ system and recommended key length is 1024.
To create a key pair using
rsa format:.
To create a key pair using
dsa format:
The ssh–keygen utility generates two files:
id_rsa.pub and id_rsa.pub (or
id_dsa.pub and id_dsa.pub).
◆ Generate the key with or without a pass phrase.
◆ When the key is generated with a pass phrase, your private key is stored encrypted
in the file.
◆ When a pass phrase is not specified, the key is stored unencrypted in the file.
NOTE: For additional information about the ssh–keygen utility and rsa and dsa
key formats, consult your SSH client documentation.
$ ssh–keygen –b 1024 –t rsa
$ ssh–keygen –b 1024 –t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/usr/user3/.ssh/id_dsa):
Created directory '/home/usr/user3/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/usr/user3/.ssh/id_dsa.
Your public key has been saved in /home/usr/user3/.ssh/id_dsa.pub.
The key fingerprint is:
3f:a0:b5:6a:4d:dd:45:76:37:fb:a3:3e:52:44:55:32 [e-mail]
NOTE: The pass phrase must be entered and decrypted before running a script.
Running the
ssh–agent and ssh–add commands decrypt the key (see step 6
on page 3.26).
