Problems with Telnet

Not sure if this is in the right section?

I am having problems with the telneting the router in my network.

There are about 10 sites with routers, i remotely conenct to different sites throught there servers. I connect to a server and then run a telnet session to try and connect to the router but everytime i try says "router unavailable on port 23". There is only one router out of the whole ten i can telnet to from the local server. I need to be able to telnet from the local server and from the servers in the main base.

Here is the config for the routers that i cant telnet to, the second config is for the router i can telne to locally.

1st>>>

line vty 0 4

access-class 70 in

exec-timeout 0 0

password 7 (*************)

transport input ssh

access-list 70 remark Modem Management

access-list 70 permit 10.0.0.0 0.0.255.255

access-list 70 permit 10.10.0.0 0.0.255.255

2nd>>>>>> i can telnet to

line vty 0 4

access-class 70 in

exec-timeout 0 0

password 7 (**************)

transport input ssh

access-list 70 remark Modem Management

access-list 70 permit 10.0.0.0 0.0.255.255

access-list 70 permit 10.10.0.0 0.0.255.255

I didnt originally setup routers and only have to get them telneting so i can then hand the service of them to new company.

Cant understand why not working, if unable to resolve soon i have many old pcs laying around to use a deticated pcs to connect up the router directly through console port but would just like to have telnet.

Thanks

Re: Problems with Telnet

I am not entirely clear on your situation. It sounds like you can connect to 9 of the 10 routers. For the one you cannot connect to, I would guess there is a firewall or some other device blocking access to port 23.

Re: Problems with Telnet

I cant connect to 9 out of the 10 routers from the server at that site. Cant connect to any from the main site. There are no firewall restrictions, if there was i would still be able to telnet from the local server i think?, but have made sure no firewall restrictions. Was wondering if there are any timeouts.

I didnt set these routers up and we have had a few other issues that were hard to work out because of the person who configured.

Re: Problems with Telnet

take of the transport in ssh, you dont need it and it could be restricting your telent... ssh is NOT telnet

Re: Problems with Telnet

You config only permits ssh, but instead of permitting telnet if I dont have to I would keep "transport input ssh" and use openssh or putty to hit my routers.. Why have your ID/Password cleartext if you dont have to?
