Figure A14-1. Model 5390 Server TCP/IP Gateway
LAT-to-Telnet Gateway
The LAT-to-Telnet gateway allows the Model 5390 server to translate an advertised LAT service to
a telnet connection for a specific IP address. This allows a LAT user to move transparently between
the LAT, TCP/IP, and Telnet protocols.
To set up the LAT-to-Telnet gateway, the system administrator must add a translation directive to
the gateway section of the configuration file. This new entry has the following syntax:
annex ip_address
translate lat service_name [identification id_string] to telnet
ip_address [port_number]
end
For example, a translation entry for a UNIX system named frodo running TCP/IP with the IP address
132.0.0.50 and a VMS host running LAT would look like this:
annex 132.0.0.35
translate lat frodo identification ’Login service for TCP/IP
host ’frodo’ to telnet 132.0.0.50
end
After making the above translation entry in gateway, the system administrator must make sure that
the Model 5390 server is running LAT and that the group_value parameter is configured so that
the LAT host can use this service. Also, the Model 5390 server must be rebooted.
Using the above sample entry, after the Model 5390 server is rebooted, the LAT user will see an
entry for frodo in the services display and the host field will correspond to the service_name set in
TCP/IP
