I am in need of some help with reverse telnet on a 2509. I set up a 2501_A to reverse telnet into a 2509 and from there I want to go into another 2501_B. I have set up the following:

on 2501_A:
===============================
interface Loopback0
ip address 10.0.0.1 255.0.0.0

line con 0
password xxxxx
login
transport input pad v120 telnet rlogin udptn
line aux 0
modem InOut
transport preferred none
transport input all
speed 19200
flowcontrol hardware
line vty 0 4
login


2509:
============================
interface Loopback0
ip address 172.1.1.1 255.0.0.0
!
....
!
interface Async1
ip unnumbered Loopback0
ip tcp header-compression passive
async dynamic address
async mode interactive
.....

line con 0
line 1 8
session-timeout 20
no exec
exec-timeout 0 0
session-limit 3
modem InOut
transport input all
flowcontrol hardware
line aux 0
modem InOut
transport preferred telnet
transport input all
rxspeed 38400
txspeed 38400
flowcontrol hardware
line vty 0 4
exec-timeout 60 0
password xxxxx
login




when I do a telnet 10.0.0.1 2001 it gives me :

Router_A#telnet 10.0.0.1 2001
Trying 10.0.0.1, 2001 ... Open


and I can't do anything from there except exit out CTRL-SHFT-6-x. How do I get from the TS to the other 2501..
I have the octal cable plugged into 2501_B CON is that right? I also have a stright thru from 2501_A AUX to 2509 CON. Thanks
 
Reverse telnet is basically used to verify PPP connection without dialing in to router. I think its normal
 
Hi guys,
I would like to track cisco running/startup configuration changes and log them to syslog. What is the best practice

Thanx
 
OK, I have a similar question. I'd like to use the aux port on a 7000 chassis to connect to the DCE control port on a Kentrox T3 CSU. It would save the extra terminal connection.

Has anyone done this?
