The Port Server and Rotaries
Define rotaries in the rotary section of the configuration file. Defining rotaries allows using a name
instead of a range of numbers when selecting a port. For more information on creating/using the
configuration file and syntax rules for rotary entries, see Configuring Hosts and Servers starting
on page A14-1.
A virtual CLI connection permits access to CLI commands from anywhere on the network. This
provides remote system management for administrators.
When a user requests a rotary, the port server attaches the user to the first available port. However,
if the requested port is busy or all ports in a requested rotary are busy, the port server asks if the
user wants to wait. This feature is called camp-on. If the user chooses to wait, the Model 5390 server
puts the request in a first-come, first-served queue and notifies the user when a port is free. Also,
the rotary can be configured so that the user either always waits, or never waits. The Model 5390
server supports ranges of port numbers that, when entered with the telnet or rlogin commands, are
mapped directly to a port or to a defined rotary.
Camp-on
Camp-on is provided when all ports in a rotary are busy or when the specified single port is busy.
The following example uses Figure A4-1 to illustrate the camp-on feature. A user at a terminal
connected to 5390_02 logged into HostB using rlogin and wants access to a modem connected to
port 6 on 5390_01.
NOTE:
The rlogin command supports connections to defined port rota-
ries only. rlogin does not support connections to the conversational port
server and to the virtual CLI.
NOTE:
You can set up security for both the port server and the virtual
CLI connections.
