Setup and Install

Port requirements
DSS 4.91 uses a number of industry standard network protocols and their corresponding TCP and
UDP ports in order to facilitate its Digital Sending functionality, such as Send to E-mail, Send To
Folder, Authentication, and LDAP Replication. This section gives an overview of which ports are used
in different configurations.
In its most basic configuration, DSS 4.91 requires ports 1783, 5213, 7627 and 161 to function. At
install time DSS will register itself with the desktop firewall to ensure connections are allowed on
these ports. Administrators may refer to the table in this section to determine which ports are required
for their specific configuration of DSS 4.91.
Ports used
DSS uses the TCP/IP protocol to communicate on the network. Which TCP or UDP ports are used
depends on which features are enabled in DSS 4.91 and which underlying protocols facilitate these
features. Also, note that for each protocol DSS acts as a server or client, or both. The following table
provides an overview. Administrators should ensure that the required ports are open at appropriate
points in the network, for example, desktop firewall, switches and routers.
