Setup

The 1841 router is connected to the network and have an IP address. The AUX port on the router is connected to the console port of the SRX240 with a blue Cisco RJ45-RJ45 Rollover cable.

Configuration

Router><input>enable</input>
Router#<input>configure terminal</input>
Router(config)#<input>line aux 0</input>
Router(config-line)#<input>password cisco</input>
Router(config-line)#<input>login</input>
Router(config-line)#<input>transport input all</input>

The telnet port on the router is 2000+line number. We find the line number with:

Router#<input>show line</input>
   Tty Line Typ     Tx/Rx    A Modem  Roty AccO AccI  Uses  Noise Overruns  Int
*     0    0 CTY              -    -      -    -    -     2      0    0/0      -
*     <notice>1</notice>    1 AUX   9600/9600  -    -      -    -    -     2      0    0/0      -
*   194  194 VTY              -    -      -    -    -     4      0    0/0      -

Now test it by telnetting to an ip address on the router and use port 2001
