I faced with a problem in a solution as follows :

+ The task is about using a module NM 16-A ( It is Not NM 16-A/S ), to obtain a console connections from a Router 2811 to another Router 2811 too.

+ I used a Configuration from Cisco site , Using this URL :

http://www.cisco.com/en/US/tech/tk801/tk36/technologies_configuration_example09186a008014f8e7.shtml

But it did'nt work , it gave me (( Connection refused by a remote ... ))

when I put the router hostname , or ip and port no

+ I put these configuration as follows:

Router (1)

ip host 3640-1 2001 172.21.1.1

ip host 3640-16 2016 172.21.1.1

ip host 3640-15 2015 172.21.1.1

ip host 3640-14 2014 172.21.1.1

ip host 3640-13 2013 172.21.1.1

ip host 3640-12 2012 172.21.1.1

ip host 3640-2 2002 172.21.1.1

interface Loopback1

ip address 172.21.1.1 255.0.0.0

line 1 16

session-timeout 20

no exec

exec-timeout 0 0

Router (2)

I Did'nt add any configuration except the enable password and the enable secret .

+ The questions is :

- does there is any additinal configuration ,which I must add to make the system work ??

- could I add some configuration to the second router to change the situation ??

- Does any of you have any good documents helping in this situation ???

Please it is Urgent ,

Thank you for your help ,
