CPS appliance
A CPS serial over IP network appliance is an Avocent managed appliance that
provides a Telnet server and an SSH server for accessing serially attached devices over
a standard TCP/IP connection. Model numbers include the CPS810 and CPS1610
appliances.
Database replication
Database replication is the process of distributing and keeping in sync the same
database to all DSView 3 servers in a DSView 3 software system. Database replication
ensures that all database changes made at the hub server or spoke servers are replicated
to all DSView 3 servers in the DSView 3 software system.
The DSView 3 management software versions of the spoke server and hub server must
match in order to register the spoke server. For example, you may not register a spoke
server running DSView 3 software version 3.1 with a hub server running DSView 3
software version 3.2.
DHCP (Dynamic Host Configuration Protocol)
DHCP is an Internet protocol used to automate the configuration of computers using
TCP/IP. DHCP can be used to do the following:
• Assign IP addresses automatically
• Deliver TCP/IP stack configuration parameters, such as the subnet mask and default
router
• Provide other configuration information, such as printer addresses
Digital Certificate
A digital certificate is an attachment to an electronic message used for security
purposes. The most common use of a digital certificate is to verify that users sending a
message are who they claim to be, and to provide the receiver with the means to
encode a reply.
An individual wishing to send an encrypted message applies for a digital certificate
from a Certificate Authority (CA). The CA issues an encrypted digital certificate
containing the applicant's public key and a variety of other identification information.
The CA makes its own public key readily available through print publicity or perhaps
on the Internet.
The recipient of an encrypted message uses the CA's public key to decode the digital
certificate attached to the message, verifies it as issued by the CA and then obtains the
