hello all, i am having difficulty in configuring a reverse telnet session between 2 cisco routers.

i have a Cisco 3825 router, which i will use as the aux 0 port. my settings for this port are as follows;

UK-VPN-RTR-3825-01#sh run | b line aux
line aux 0
 exec-timeout 0 0
 modem InOut
 transport preferred telnet
 transport input all
 transport output telnet ssh
 stopbits 1
 flowcontrol hardware

i then have a straight RJ45 network cable going from this router aux port, to the console port of the Cisco 2811 router which i would like to establish a reverse telnet session to.

as i understand it, i need to telnet to the ip address of the 1st router, and on port number 2000 + line number. i do a sh line command, the line number for the aux port is 1. so, i telnet as follows;

telnet 10.0.50.3:2001

nothing happens.

when i do a show line 1 on the aux router, i notice that the modem hardware state says - nocts. i believe this is not good.

please can someone help me?

thanks in advance
