Flowchart 1 Procedures

A.	Execute: ping to remote host.Using ping(1M), send
	a message to the remote host to which you are having
	problems connecting. For example:
	ping spiff
B.	ping successful? A message is printed to stdout for
	each ping packet returned by the remote host. If
	packets are being returned, your system has network
	level connectivity to the remote host. Note what
	percentage of the total packets are lost, if any. Losing
	ten percent or more may indicate the network or
	remote host is extremely busy. You may also ﬁnd it
	useful to note the round-trip transmission times.
	Periodically high transmission times may indicate that
	the network or remote host is extremely busy.
	Consistently high transmission times may indicate the
	local host is extremely busy. If a message is not
	returned after executing ping, ping is not successful.
	Do Cntrl C to stop the ping output.
C.	Network unreachable? If yes, go to ﬂowchart 3 to
	display connection status using the lanscan(1M)
	command.
D.	Command hangs. If a message is not returned after
	executing ping, go to ﬂowcharts 2 through 7, referring
	back to ﬂowchart 1 (ping) until you have corrected the
	problem.
E.	Unknown host? If you receive this message, go to step
	F.
F.	Correct BIND, YP or hosts conﬁguration. Add the
	missing host name and start again with ﬂowchart 1.
G.	No route to host? If Error= Sendto: No route to
	host, go to Step H. Otherwise, call your HP
	representative for help.

H.Add route table entry. Using route, add a route table entry for that host. Refer to the route(1M) online man page for more details. Start again with ﬂowchart 1.
