The Port Server and Rotaries
In the next example, a user requests TCP port number 5006 using the telnet command:
% telnet 5390_01 5006
Trying...
Connected to 5390_01.
Escape character is "^]".
Attached to port 6.
TCP port numbers in the 6000 range are used when defining rotaries in a file (i.e., a TCP port number
in the 6000 range can be assigned to a single rotary). Issuing a Telnet connection request to such a
TCP port results in directly attaching to the rotary (see Rotaries on page A4-9 for more details).
TCP port numbers in the 7000 range also provide a direct-mapped connection, but do not use the
Telnet protocol. These TCP ports are similar to raw connections in that they pass data directly to
and from the serial port.
Virtual CLI Connections
The Model 5390 server can access the CLI from anywhere on the network through the port server.
It creates a virtual CLI connection for the user when either a CLI is requested at the port server
prompt or the TCP port number 5000 is included in the telnet command.
Using a virtual CLI, you can access any CLI command. However, of all the port characteristics,
only the attention character (or character string) affects the virtual CLI connection. You can define
the attention character or character string using either the Model 5390 parameter attn_string or the
stty attn command (see attn_string on page C2-11 for more details). The attention character (or
character string) provides access to the CLI while in a session with another host.
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.
