Access Server Config

I just configured my access server but I am having trouble connecting to my routers and switches through it. Does the ip host entry name on the AS need to match the hostname on the device I am trying to connect to?

Here is the config:

AS_2509#show conf
Using 935 out of 32762 bytes
!
version 12.1
no service single-slot-reload-enable
service timestamps debug uptime
service timestamps log uptime
service password-encryption
!
hostname AS_2509
!
enable secret 5 $1$fGt1$YCEIlemXC0OcfeUp8RkCa/
enable password 7 001012050F570E040039

No, the hostnames don't have to match. You should take your passwords out of that config too, especially the password 7. I'll check out my config and see if I can spot anything with yours.

Config looks good to me. Here's mine:

ip subnet-zero
no ip domain lookup
ip host SW3550 2001 192.168.0.1
ip host SW2950a 2003 192.168.0.1
ip host SW2950b 2004 192.168.0.1
ip host R3640a 2005 192.168.0.1
ip host R3640b 2006 192.168.0.1
ip host R1760 2007 192.168.0.1
ip host R2611 2008 192.168.0.1
ip host R2514a 2009 192.168.0.1
ip host R2514b 2010 192.168.0.1

Is your loopback showing up up?

boostinbadger

Yeah it is showing up in the config. I can't figure it out. Could it be the passwords?

ColbyG

What exactly is happening?

boostinbadger

At priv exec I type R1 and it says "Invalid input detected at "^"

the ^ is under the R of R1

ColbyG

Try it lowercase.

Edit: Nevermind, just tried mine caps and it worked. I always do it lowercase cause I'm lazy.

ColbyG

Wait, are you trying it in config mode? When I try it in exec it tries to resolve it. I only get your error in global config.

boostinbadger

Nope. Exec mode gives me the same error.

I just noticed that the LED next to the ASYNC 1-8 octal cable is not lit. If I loosen it almost completely and wiggle it the LED will flash intermittently. Should that LED be lit solid if it is working properly?

No. It is an activity light.

What happens if you type:
telnet 100.1.1.1 2001
Does that work?

By the way he's just telling you to take your password 7's out because we all now know that your console and enable passwords are tacklebox.

boostinbadger

The password doesn't matter. It is a generic one I used.

dtlokee

You can't just type in the hostname "R1" when connected to the console becaue you have the "transport preferred none" under the line con 0 configuration. You will need to use "telnet R1" or add the "transport preferred telnet" under the "line con 0" configuration.

boostinbadger

I will give that a try when I get home to the lab. Thanks dtlokee.

boostinbadger

Great! It works now. It does take a long time to "translate" though. After the connection is opened it is normal speed.

boostinbadger

no ip domain-lookup fixed the slow connection problem. I usually issue this command anyway but I guess I forgot it.
