[c-nsp] 2801 as console server
I've been looking through the Cisco doc but didn't found what I was looking for, therefor this question : I transformed a 2801 router which we used as a dialin server to a console server. The config seems to work, I can do a telnet xxx 2018 to get access to serial port 0/1/1, also ssh -l user:portnumber works. But I still have 2 problems : -The escape character doesn't work when using ssh, also e.g. defining CTRL-Z as disconnect character doesn't work. The only way to stop the connection, is by killing it at the ssh client side. Is there another way to stop the ssh connection, just like the telnet escape character ? -Is there a way to access the async line from within the router itself ? So just a telnet/ssh to the router and then something like 'connect line XXX' ? The connect command on the router seems an equivalent of telnet for outgoing tcp sessions and I don't see another command that could do this. I'm running c2801-ipbasek9-mz.124-25a on the router.

The connect command on the router seems an equivalent of telnet for outgoing tcp sessions and I don't see another command that could do this. I've done this in the past by connecting to an IP address on the router - the one assigned to the ethernet interface for example. We use a 2511 as a console server for last resort access to devices. In the worst case scenario if the ethernet interface is down we access it via the console port. If that's the case then the ethernet IP address won't be reachable. I've assigned a loopback IP address (192.168.0.0/32 I think) and use that instead (router telnet 192.168.0.0 2001) Hope this helps. -Ronan ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

Re: [c-nsp] 2801 as console server
If you use the 6018 instead of 2018 you should find the control characters escape characters etc work. 2xxx are 7 bit connections 4xxx give echo - you don't want that 6xxx are 8 bit connections. Don't remember trying it with ssh but the 6xxx are certainly better for connecting to Cisco devices via TS as it even allows you to get at the boot loader if you need to - however that does obviously have security implications!!
