Terms:
The following terms are used in this document. Please familiarize yourself with them.
The products: This refers to the digital multifunction and printing devices covered by this document, as
noted in the Model Cross Reference table. The term “the products” refers to all of these machines
collectively.
Host Interface: This refers to the physical interface of the Ethernet board on “the products”.
SSL: SSL is a communication technology used for secure connections between 2 hosts. The primary
goal of the SSL Protocol is to provide privacy and reliability between two communicating applications.
SSL is layered on top of some reliable transport protocol (e.g., TCP). SSL allows the server and client to
authenticate each other and to negotiate an encryption algorithm and cryptographic keys before the
application protocol transmits or receives its first byte of data.
SSH2 (Secure Shell) is intended as a replacement for rlogin, rsh, and rcp. Additionally, ssh provides
secure X connections and secure forwarding of arbitrary TCP connections. Ricoh’s implementation of
SSH is based on OpenSSH 3.9.
Model Cross Reference:
The products: This refers to the digital multifunction and printing devices covered by this document, as
noted in the Model Cross Reference table. The term “the products” refers to all of these machines
collectively.

NOTE: Parts of this document may not apply to some models. For example, printer models do not have
scanners. Therefore some uses of RSH (for scanning) do not apply to these models.
