Does anyone know how to terminate a Telnet session coming into your Router?

    Not sure what you mean by this question do you want to prevent people from telneting in or disconnect people that are already connected>

    Easiest way to prevent telnet from coming in is by applying an access list
    can be done one of two ways, to allow only you to telnet in from a known IP
    Router(config)#access-list 50 permit {you IP address}
    Router(config)#line vty 0 4 (applys the access list to 0-4 telent sessions)
    Router(config-line)#access-class 50 in (notice this is different from applying to physicial interface)

    or to deny any
    Router(config)#access-list 120 deny tcp any any eq 23
    Router(config)#access-list 120 permit ip any any
    RouterA(config-if)#ip access-group 110 in

    If you mean disconnect someone already connected, correct me on this anyone

    Router#Show users
    work out which line number is connected then
    Router#disconnect {connection-number}
    Looking for CCIE lab study partnerts, in the UK or Online.

    Yes, that is exactly what I mean. Terminating another user who is already connected to the router you are currently working on
