15. Advanced Configuration
15.6.2 Generating Public Keys (Linux)
To generate new SSH key pairs, use the Linux ssh-keygen command. This will produce an RSA or DSA public/private key pair.
You will be prompted for a path to store the two key files e.g. id_dsa.pub (the public key) and id_dsa (the private key). For
example:
$ ssh-keygen -t [rsa|dsa]
Generating public/private [rsa|dsa] key pair.
Enter file in which to save the key (/home/user/.ssh/id_[rsa|dsa]):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/user/.ssh/id_[rsa|dsa].
Your public key has been saved in /home/user/.ssh/id_[rsa|dsa].pub.
The key fingerprint is:
28:aa:29:38:ba:40:f4:11:5e:3f:d4:fa:e5:36:14:d6 user@server
$
It is advisable to create a new directory to store your generated keys. It is also possible to name the files after the device for
which they will be used. For example:
$ mkdir keys
$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa): /home/user/keys/control_room
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/user/keys/control_room
Your public key has been saved in /home/user/keys/control_room.pub.
The key fingerprint is:
28:aa:29:38:ba:40:f4:11:5e:3f:d4:fa:e5:36:14:d6 user@server
$
You must ensure no password is associated with the keys. If there is a password, the Tripp Lite devices will have no way to
supply it as runtime.
