New Post: SSH to terminal server and then TELNET to devices

I was successful in SSH to terminal server. However, when I telnet to a device from there, it just hangs up. It is waiting for Username as input. How do I solve this?

I need to SSH to Server
From Server telnet to Router
(Enter Username and Password)
Run "Show Run" on the router.

Any help is much appreciated.

Thanks in advance.
