HP SUM allows you to log in with root credentials and an SSH key.
-
Save the key in the directory
.ssh /id_rsa.pub
.Verify that the private key is in PEM format by opening the key and viewing the top of the key for the following text:
-
If necessary, on the node you want to update, create an .ssh directory at the root level. Set the permissions level on the directory to 700.
-
Determine if the node you want to update has the file
.ssh/authorized_keysfile
. If this file is not present, create or append this file. Set the permissions on theauthorized_keys
file to 640.
NOTE: If you append the file, more users are authorized to use the private key.
-
Copy the contents of
.ssh/id_rsa.pub
on the host node, and then paste them into tho the.ssh/authorized_keysfile
on the remote node. -
Open an SSH path between the host node and the node you want to update.
-
HP SUM requires access to
id_rsa
(private key file), and the passphrase, if you created a passphrase.
NOTE: If other applications require the public key in PEM format, you can convert it by typing
ssh-keygen -e -f id_rsa.pub > id_rsa_pub.pem
. Open the key, and look at the PEM format for---- BEGIN SSH2 PUBLIC KEY ----
.
To create a private key on a Windows system, you can use an application like PuttyGen. For more information, see:

To export the file to PEM format, select, Conversion → Export OpenSSH key.
