How certificates are used. Most Web browsers, including all browsers supported by
Rack PDUs, contain a set of CA root certificates from all of the commercial Certificate
Authorities.
Authentication of the server (in this case, the Rack PDU) occurs each time a
connection is made from the browser to the server. The browser checks to be sure that
the server’s certificate is signed by a Certificate Authority known to the browser.
For authentication to occur:
• Each server (Rack PDU) with SSL enabled must have a server certificate on the
server itself.
• Any browser that is used to access the Web interface of the Rack PDU must contain
the CA root certificate that signed the server certificate.
If authentication fails, a browser message asks you whether to continue even though it
cannot authenticate the server.
If your network does not require the authentication provided by digital certificates, you
can use the default certificate that the Rack PDU generates automatically. The default
certificate’s digital signature will not be recognized by browsers, but a default certificate
enables you to use SSL for the encryption of transmitted user names, passwords, and
data. (If you use the default certificate, the browser prompts you to agree to
unauthenticated access before it logs you on to the Web interface of the Rack PDU.)
How SSH host keys are used. An SSH host key authenticates the identity of the
server (the Rack PDU) each time an SSH client contacts that server. Each server with
SSH enabled must have an SSH host key on the server itself.
