Networking

This section provides information necessary to administer Reality networking on both UNIX and Windows. It describes:

Introduction

Reality provides the following networking facilities:

Types of Network

UNIX

The standard networking facilities are supported between one Reality database and another. The two hosts must be able to connect via a network - the network may be a Local Area Network (LAN), an X.25 network or, with the use intermediate gateways, any combination of these.

LAN

Both hosts must be fitted with LAN controllers. A LAN connection may use TCP/IP or OSI (either full network or null network).

Note

For OSI connections, the Transport Services product must be purchased.

X.25

Both hosts must be fitted with X.25 controllers.

Windows

The standard networking facilities are supported between Reality databases on Windows hosts, and remote Reality and RealityX databases. Only the TCP/IP protocol is supported. If you need to connect via OSI or X.25, you must connect via a UNIX gateway.

Session Manager

The Session Manager is a dedicated background process which accepts incoming connections for the local host and maintains event and session logs which are used to record significant events and errors during the processing of incoming/outgoing connections. The Session Manager also carries out security checking.

TCP/IP Ports

By default, Reality uses the following TCP/IP ports:

23 Telnet session manager (Windows only).

1400 Unix-Connect Telnet LBS (UNIX only).

1777 GUI Administration Server.

1203 Reality session manager (DDA).

1900 UNIX-Connect character circuit to a printer.

2001 Failsafe authentication.

2002 GUI Administration Server configuration.

3000 Reality Perl server.

3080 Reality mini web server.

3995 Java Web Start.

52001 Reality remote tape server.

If your users access your network through a firewall, you will need to enable one or more of these ports.
