PC-Duo overview

PC-Duo networking features

PC-Duo remote desktop solutions support several standard transport protocols for

computer-to-computer communication, and two types of network addressing schemas.

Network protocols

PC-Duo products support most of the standard networking and transport protocols,

including:

 IP: IP is a general-purpose protocol supported on a wide variety of networks and

servers. PC-Duo components support communications using either the TCP or UDP

transport protocols running over IP. PC-Duo has established the following standard ports

for use with either TCP or UDP:

 PC-Duo Host listens on port 1505 by default

 PC-Duo Gateway listens on port 2303 by default

 IPX: IPX provides access to Novell NetWare servers. PC-Duo components support

communications using this protocol.

 SSL: The SSL protocol runs above TCP/IP and below higher-level protocols such as

HTTP or IMAP. Using TCP/IP on behalf of the higher-level protocols allows an SSL-

enabled server to authenticate itself to an SSL-enabled client, and then establish an

encrypted connection between the remote computers.

 By default, PC-Duo Gateway listens for incoming SSL connections on port 443, but

it might be appropriate to note that this can be easily changed to avoid conflicts with

other server software installed on the same machine.

 The PC-Duo Gateway now ships with a Gateway Certificate Manager to manage

the creation and/or selection of a SSL security certificate for the PC-Duo Gateway.

Network addressing schemas

The PC-Duo UDP, TCP and SSL transport protocols support the use of either IPv4 (32-

bit) or IPv6 (128-bit) addresses.
