I have a problem with my Cisco router. I can't get access to it through con/aux port. Router responds only to telnet request "Password required but none set"and then it closes connection. When I try to get access with COM it shows nothing. Router does get IP from WAN and it responds to pings. It doesn't have services such as SSH and HTTP. It has only telnet port open.
Thanks in advance.
can you check if the right COM port is used?
also check if terminal program settings are correct: 9600-8-N-1-N
you're getting the error "Password required but none set" since there's no VTY line passwords were configured.
do you have a copy of the show run? post a sanitized output here.
