Metered 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 Rack PDU):
•A 1024-bit host key created by the APC Security Wizard.
•A 768-bit RSA host key generated by the 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 Metered Rack
PDU Utility CD.
N
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 an SSH client installed. Most Linux and other
UNIX
®
platforms include an SSH client, but Microsoft Windows operating
systems do not. Clients are available from various vendors.
