5: Using the MSS

TCP/IP Socket Connections

Note: TCP/IP socket connections applies to MSS-VIA only.

The MSS supports TCP/IP socket connections to ports 2001 and 3001.

Note: Starting with firmware v3.6/8, the MSS-VIA supports socket connections to port 2002 and 3002 also (to reach the DB9 serial port).

Opening a TCP session to a 300n port will form a raw TCP/IP connection to the serial port. Use a 200n port when you need Telnet IAC interpretation.

To specify a connection to a socket, use the Telnet command followed by the MSS IP address (or resolvable name), a space, and the desired socket number.

Interactive Connections

Interactive mode refers to entering commands at the Local> prompt. Commands can be used to configure the MSS, connect to remote services, manipulate a connection, or receive feedback. Interactive use requires an input device, such as a terminal.

Outbound Connections

When logged into the MSS, users can make basic outgoing connections using the method described in this section. See the MSS Reference Manual on the CD-ROM for more information about incoming and outgoing connections.

Telnet

To start an outgoing Telnet session, type Telnet at the Local> prompt, followed by either the host's name or its numeric IP address.

Note: If a preferred service has been configured, a host name is not required.

Local> TELNET 192.168.0.10

Note: Initiate outgoing Telnet sessions from the serial ports. Incoming Telnet sessions cannot initiate an outgoing Telnet session.

You can also make a Telnet connection to a specific port number, as described in Serial Tunnel.

Rlogin

Rlogin allows a user to log into a remote host as if he or she were a local user. In the example below, shark is the remote host and lola is the username. Unless the username is password protected, the user will be logged in normally.
