Remote Console connection

[Dante Ranada]

I was able to connect to the console from another system in the data center. However, I can't connect to the same console from outside the data center using my workstation and othe systems on the network. Any idea why I can't establish a connection. This is the message I get when I try to telnet to the console. "telnet: Unable to connect to remote host: Connection refused. BTW: I'm able to ping the console.

Thanks,

Hi,

Check your access control settings. Did you restrict telnet to only specific source IP addresses?

Hope this helps. Regards.

Are you on a different network when you are outside? Could be the PC you are getting to is not the one you want.

While inside the data center on a PC which can reach the Console do
nslookup Consolehostname

Where Consolehostname is the hostname you are trying to get to.

Repeat the nslookup on the outside machine. Compare IP addresses. Are they the same?

Try a traceroute and see where it goes. Try telneting to the ip address instead of the hostname.

Are we going through a firewall or NAT in order to get there.

If you are really getting to the same machine then there must be a security file somewhere which tells it who it is allowed to talk to based on the source ip address/hostname. One of the security gurus will have to help you there. I'm mostly just a network guy.

Hi Dante,

Looks like a firewall or a route issue to me. If you are using a workstation go to the ms-dos prompt and run the tracert command with the ip address of the server you want to connect,

tracert ip_add_of_server

Make sure there is no firewall sitting between the workstation you are using and the system you are trying to connect.

Hope this helps.

Hi,

Since you can ping the console,
1) the hostname can be resolved to IP address
2) there is a valid route to the console

The possible ACL points include
1) router
2) firewall
3) server
4) client (you could be blocking outbound telnet access)

Hope this helps. Regards.

Thanks for everyone's input. I really appreciate your time in responding to my question. I got it fixed: I had an active login session with the console. I forget to close my telnet session in the data center before I left. I thought I logged out but I didn't.

Thanks again for your time.
