Switched Rack PDU

ssh host

key

Status indicates the status of the host key (private key):

• SSH Disabled: No host key in use: When disabled, SSH cannot use a host key.

• Generating: The Rack PDU is creating a host key because no valid host key was

found.

• Loading: A host key is being activated on the Rack PDU.

• Valid: One of the following valid host keys is in the /sec directory (the required

location on the Switched Rack PDU):

• A 1024-bit host key created by the APC Security Wizard

• A 768-bit RSA host key generated by the Switched Rack PDU

Add or Replace: Browse to and upload a host key file created by the Security

Wizard:

If you use FTP or SCP instead to transfer the host key file, you must specify the

/sec directory as the target location in the command.

To use the APC Security Wizard, see the Security Handbook on the Switched Rack

PDU Utility CD.

OTE: To reduce the time required to enable SSH, create and upload a host key in

advance. If you enable SSH with no host key loaded, the Rack PDU takes up

to 5 minutes to create a host key, and the SSH server is not accessible during

that time.

Remove: Remove the current host key.

To use SSH, you must have a SSH client installed. Most Linux and other

UNIX

platforms include a SSH client, but Microsoft Windows operating

systems do not. Clients are available from various vendors.
