help on cisco 2509 -rj access server
hi,
i set up a home lab for ccna ccnp.
i have a rack with plenty cisco equipment and i bought a 2509-rj router to manage the other device.
i'm having trouble configuring it since i cannot telnet to the devices connected to async ports.
here is show run:
Router#show run
Building configuration...
Current configuration:
!
version 11.3
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname Router
!
!
ip host host1 2001 192.168.0.1
!
!
!
interface Loopback0
ip address 192.168.0.1 255.255.255.255
!
interface Ethernet0
ip address 192.168.1.10 255.255.255.0
!
interface Serial0
no ip address
no ip mroute-cache
shutdown
no fair-queue
!
ip default-gateway 192.168.1.1
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.1.1
!
!
line con 0
line 1 8
session-timeout 20
no exec
exec-timeout 0 0
transport input telnet
transport output telnet
line aux 0
line vty 0 4
!
end
the idea was to keep the rack in a separated subnet 192.168.0.0/24, my home lan is 192.168.1.0/24.
i connected a transceiver to AUI port and gave address 192.168.1.10
i created a loopback interface 192.168.0.1/32
fissued the folowing commands.
router(conf):ip host host1 2001 192.168.0.1
router(conf):line 1 8
router(conf-line):transpor t input telnet
when i try from the router to telnet the connected device (a 2620xm) it says:
Router#telnet host1
Trying host1 (192.168.0.1, 2001)...
% Connection refused by remote host
Router#telnet 192.168.0.1 2001
Trying 192.168.0.1, 2001 ...
% Connection refused by remote host
and the same from a host in home lan, i can telnet te 2509 but not the devices connecte to it...
hope you can help,
paolo.

hi again,
i found out that was missin the command "no exec" in the lines.. but now i can estabilish a connection, but immediatly after that it hang and the console session to the 2509 blocks.
the only way to gai acces to the router back is to telnet into it and reboot. or switch in off and on again...
any idea why? may it be the 2509 not working properly?
thats what happens:
TS#R2500
Trying R2500 (192.168.0.1, 2002)... Open
then it blocks...
paolo.

well honestly i missed this command before.. as far as i understand i see notthing strange
i don't know about the no exec command since before using it i wasn't able to see connected devices and inoticed that in sh line tab the lines with a connected device were reporting overruns.
i guessed was something about noise on the line...
for the cables i actually used a "factory-made" rj-45 to rj-45 cisco blue rollover for line 1 and anotherone i made by myself by cutting a classic rj45 to rs-232. is quite simple since the order of pins is simply the opposite and moreover it's a flat cable so i shouldn't have done wrong..
thanks for helping!

Nope, this i a 2509-rj it has 8 rj45 async port, is The same to configure but uses 8 rj45 to rj45 rollover cables.. Same as normal cables but with inverted pins.

sorry for slow answer but i got busy working...
yes, i tried configuring a password for they vty, and there shouldn't be an acl since i just erased startup... yeah i can ping it, i used it a lot of time for creating lab scenarios..
anyway i suppose this isn't a matter of telnet, or anyway notting regarding the 2620xm.. symply because since it is a terminal server, i should be able to just connect and power on a new device and then configure it without a pc.. if it would require allso just one command to be issued in the connected devices, it would be useless.
any command missing in the 2059? iwas wondering how does the router estabilish a telnet connection trought a console port... shouldn't they be compleetly different protocols?
i found a command to set the lines as "terminal" may i need this?
thanks!
