Switched Rack PDU

SSH User Host Key File
Status: The Status field Indicates the status of the host key (private key). In the
control console, you display host key status by selecting Advanced SSH
Configuration.
•SSH Disabled: No host key in use: No host key has been transferred
to the Rack PDU, or a host key has been transferred improperly.
NOTE:A host key must be installed to the /sec directory of the Rack
PDU.
•Generating: The Rack PDU is generating a host key because no valid
host key was installed in its /sec directory.
•Loading: A host key is being loaded (i.e., being activated on the Rack
PDU).
•Valid : The host key is valid. (If you install an invalid host key, the Rack
PDU discards it and generates a valid one. However, a host key that the
Rack PDU generates is only 768 bits in length. A valid host key created
by the APC Security Wizard is 1024 bits.)
Filename: You can create a host key file with the APC Security Wizard and then
upload it to the Rack PDU by using the Web interface. Use the Browse
button for the Filename field to locate the file, then click Apply.
Alternatively, you can use FTP or Secure CoPy (SCP) to transfer the host
key file to the Rack PDU.
NOTE:Creating and uploading a host key in advance reduces the time
required to enable SSH. If no host key is loaded when you enable SSH,
the Rack PDU creates one when it reboots. The Rack PDU takes up to
5 minutes to create this key, and the SSH server is not accessible
during that time.
