Using the MSS

5.2.2.4 LAT

LAT devices broadcast their services to the network along with ratings, which are estimates of how busy the services are. Ratings range from 0 to 255; a 255 rating means that the service can accept connections while a zero rating means that the service is in use and connection attempts will be denied. By default, connection attempts are made to the highest-rated service bearing a given name.

To connect to a LAT service, type the word ÒLATÓ followed by the service name. To view available LAT nodes and services, enter Show Nodes LAT or Show Services at the Local> prompt. The example below shows how to connect to the highest-rated service named modem on the network.

Local> LAT modem

Connections to particular hosts and ports can be forced if desired. Forcing a connection in this way may be necessary if more than one host on a network can provide a given service, or if the desired host does not have the highest rating for that service. For example, the following command will attempt a connection to a service named modem on port 5 of a VAX host named vax8.

Figure 5-13:Connecting to a SpeciÞc Port

Local> LAT modem LN=vax8:LD=0005

NOTE: If the information supplied in the command is incorrect, or if there is no such service on the specified host or port, the connection will be refused.

If the MSS has been conÞgured to allow incoming LAT logins, the MSS will also show up as a service on the network. Users can connect to the MSS from another LAT-based server by typing the appropriate connection command.
