3 The message showing successful Telnet to Router B should pop up and display the
host name of RouterB.
[RouterB]
Example of Reverse Telnet
The host is connected to the router, then communicates with the device
connected to the seventh asynchronous serial interface of the router. The IP
address of the router is 10.110.164.44.
[Router] telnet 10.110.164.44 2007
Trying 10.110.164.44...
Service port is 2007 ( tty)
Connected to 10.110.164.44
After successful Reverse Telnet, host name of RouterB will be displayed.
[RouterB]
The host can send commands to communicate with the device connected to the
asynchronous serial interface. If a modem is connected to the interface, you can
detect the modem status or configure the modem by using the AT command.
Rlogin Terminal
Service
Rlogin (Remote Login) is one of the most common Internet applications developed
by the BSD UNIX system, in which a client is connected with the server by TCP
connection. It provides the function of several remote terminals accessing the
UNIX host. Rlogin originated from Berkeley UNIX and id used for telnet service
between UNIX systems. Compared with Telnet protocol, it is easier to implement
and use Rlogin protocol.
The 3Com Router implemented by Rlogin is Client-based. Rlogin Client enables
3Com Router series to have functions similar to that of a multi-serial port card, i.e.,
digital or analog terminals that log onto routers through the terminal access
functionality and can use Rlogin protocol to log onto a remote UNIX host.
