Reverse Telnet from 2610

[Marco-D]

Hi guys
Having problems using reverse telnet. Using the AUX port on a 2610 connecting to the Console port of a 3550 switch using a straight through cable.

AUX port on 2610 is configured like this:
line aux 0
modem InOut
transport input all
stopbits 1
speed 19200
flowcontrol hardware

Loopback 0
10.0.0.1 255.255.255.0

The AUX port is on line 65 so therefore telnet 10.0.0.1 4065

I get the prompt for username and password.

The first problem was that each character I typed I got twice so I used the /noecho switch on the telnet command which resolved this. The next problem is that I enter the username and password, but I then get nothing. It locks up and accepts no further input. I have to disconnected and start again but the same thing happens everytime.

Any help appreciated.

Try port 2065 instead of 4065.

A few things.
1. You should use 2065 rather than 4065 - All the Cisco documentation
references reverse telnet via port 2000+n (n being the port number of
the line). Even though this may not help right now, this might be a
good standard practice.

2. Have you tried using a roll-over (console) cable or a crossover in
place of the straight through?

3. I notied the AUX port is set to speed 19200 on the 2610, have you
configured the same speed on the 3550? Console ports are usually only
9600 - might be a speed mismatch.

4. What does the config look like on the console port of the 3550?
