Cisco devices. Telnet makes it easy to reach the device console from anywhere simply by telnet to the terminal
server on a specific line. This telnet approach can be used to configure a device even if all network connectivity
to that device is disconnected. Reverse telnet also allows modems that are attached to Cisco devices to be
used for dial-out (usually with a rotary device).
Reverse SSH
Reverse telnet can be accomplished using SSH. Unlike reverse telnet, SSH provides for secure connections.
The Reverse SSH Enhancements feature provides you with a simplified method of configuring SSH. Using
this feature, you no longer have to configure a separate line for every terminal or auxiliary line on which you
want to enable SSH. The previous method of configuring reverse SSH limited the number of ports that can
be accessed to 100. The Reverse SSH Enhancements feature removes the port number limitation.
