HP (Hewlett-Packard) 100BASE-TX Manuel D’Utilisation

Troubleshooting 10/100Base-TX/9000

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:

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

hos

t, 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.
