Managed Rack PDU

Secure CoPy. SCP is a secure file transfer application that you can use instead of
FTP. SCP uses the SSH protocol as the underlying transport protocol for encryption of
user names, passwords, and files.
• When you enable and configure SSH, you automatically enable and configure SCP.
No further configuration of SCP is needed.
• You must explicitly disable FTP. It is not disabled by enabling SSH. To disable FTP,
on the Administration tab, select Network on the top menu bar and FTP Server on
the left navigation menu. Clear the Enable checkbox and click Apply.
Secure Sockets Layer (SSL) for the Web interface
For secure Web communication, enable Secure Sockets Layer (SSL) by selecting
HTTPS as the protocol mode to use for access to the Web interface of the Rack PDU.
HyperText Transfer Protocol over Secure Sockets Layer (HTTPS) is a Web protocol
that encrypts and decrypts page requests from the user and pages that are returned by
the Web server to the user.
The Rack PDU supports SSL version 3.0 and the associated Transport Layer Security
(TLS) version 1.0. Most browsers let you select the version of SSL to enable.
When SSL is enabled, your browser displays a small lock icon.
SSL uses a digital certificate to enable the browser to authenticate the server (in this
case, the Rack PDU). The browser verifies the following:
• The format of the server certificate is correct
• The expiration date and time of the server certificate have not passed
• The DNS name or IP address specified when a user logs on matches the common
name in the server certificate
• The server certificate is signed by a trusted certifying authority
Each major browser manufacturer distributes CA root certificates of the commercial
Certificate Authorities in the certificate store (cache) of its browser so that it can
compare the signature on the server certificate to the signature on a CA root certificate.
