A. Execute: telnet <hostname> to remote host. Try to connect using telnet
to a remote host.
B. Succeeds? If telnet succeeds, stop. The system connects using TCP over IPv6 through
the Transport Layer (OSI Layer 4).
C. Connection Refused? Trying to connect to a remote system where HP-UX 11i v2
IPv6 is not installed can cause this message.
D. If connection is refused, Execute ping to remote IPv6 “host name”. Using ping,
send an ICMPv6 message to the remote host with which you are having problems
connecting. For example, the remote host name is hpindon. Enter:
ping -f inet6 hpindon
