Solution

  • There are many possible reasons, but four come immediately to mind.

    1. The IP address is invalid.

    2. The IP address is unreachable because of an error in routing table configuration on intermediate nodes.

    3. A firewall somewhere is refusing to admit the traffic.

    4. The target host has inetd so configured as not to accept inbound telnet requests.
