Using the MSS Incoming Connections

5 - Using the MSS

This chapter explains how to use the MSS interactively and with host applications. Host-initiated (incoming) connections include:

¥Making socket connections to TCP/IP and IPX/SPX hosts.

¥Making LAT connections to VMS, Ultrix, and OSF/1 hosts.

¥Using host applications with the MSS.

¥Using the code examples included with the MSS.

Interactive uses include manipulating sessions, making outgoing connections, and viewing server and network information with the help of the Show commands.

In addition, explanations are provided for:

¥Setting up two MSS units to emulate a direct serial connection over the LAN.

¥Using the MSS as a data pipe between a serial device and multiple hosts on the network.

5.1Incoming Connections

5.1.1 Socket Connections

Each node on a network has a node address, and each node address can allow connections on one or more sockets. Sometimes these sockets are referred to as ports. TCP/IP and IPX connections can be made directly to the MSS serial port using sockets.

There are two categories of sockets. Well-known sockets are those that have been deÞned in RFCs (Requests for Comments); for example, port 23 is used for Telnet connections. There are also custom sockets that users and developers deÞne for their speciÞc needs.

NOTE: If the serial port is in use, the socket connection will be refused.
