Hi Everyone,
Would like to ask if anybody knows how to use reverse telnet in a Cisco 3845 router. Appreciate any help.
Thanks much!

Hello Napoleon,
reverse telnet is a way to provide terminal server services
you need
A/S serial lines to be used to connect other devices' console ports to them or modems
the appropriate cables.
reverse telnet is part of this solution and allows to open a session on a line (an async line) when telnetting to a specific TCP port using a loopback address
TCP port = 2000 + line#
line numbers can be seen with
sh line
ip hosts command can be used:
ip host hostname 2004 10.99.0.51

Hope to help

Hi Giuseppe,
Thanks, but I believe I can use the router's aux port for reverse telnet, I just don't know the port number to use for the 3845. I used 2001 for a cisco 7200 but it doesn't work for 3845.
thanks,
