Google (as always) is your friend

I think the product you have in mind is something like this?

An alternative that's probably cheaper, is to buy a Cisco router and use it as a terminal server through reverse telnet. A Cisco 2509 (8 Lines), 2511 (16 lines) or a 2600/3600 series with a NM-16A or NM-32A async module with a CAB-OCTAL-ASYNC cable will do you just fine.

Then it's just a matter of setting up a reverse telnet through ip host using a local IP:

Code: Select all
ip host <remote hostname> 2001 <local IP address>


Where 2001 is the async line + 2000 and local IP address is any local address.

To manage your sessions:

Hold Ctrl-Shift-6 and press "X" to jump out of your telnet session (keeps it active).

Show sessions will show you what telnet sessions are active:

Code: Select all
2511TS#show sessions
Conn Host      Address         Byte Idle  Conn Name
   1 Router1    10.1.1.10   0     0     Router1
   2 Router2    10.1.1.10   0     0     Router2
* 3 Router3   10.1.1.10   0     0     Router3


Typing "Y" and hitting enter at user/priv mode will reconnect to session "Y"

Or hitting enter with no text will return to the last active session

You could probably find a similar setup using a normal computer and a serial async card.

I have to ask the question though - what's wrong with regular telnet/ssh that you need console access at all times?

Thanks for that mate....i understand there is nothing wrong with using a normal telnet session but the routers have to have a working basic config on them before you can telnet into what ever router on the network. This lies my problem so i think ill just have make a patching board or ill use my friend Google. Thanks again for the help mate i didnt even know you can reverse telnet into a router......learn something everyday. :D
