ssh host
key
Status indicates the status of the host key (private key):
•SSH Disabled: No host key in use: SSH is disabled and is not using a host key even if one
is loaded.
•Generating: The cooling unit is creating a host key because no valid host key was found.
•Loading: A host key is being activated on the cooling unit.
•Valid: One of the following valid host keys is in the /sec directory (the required location on
the cooling unit):
• A 1024-bit host key created by the APC Security Wizard.
• A 768-bit RSA host key generated by the cooling unit.
Add or Replace: Upload a host key file created by the APC Security Wizard to the /sec
directory:
1. Click Browse.
2. Locate the file.
3. Click Apply.
If you use FTP or Secure CoPy (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 Utility CD.
Note: 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 cooling unit 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.
Note: 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. SSH clients are available
from various vendors.
