The following response is generally caused by an incorrect subnet mask
or IP address. It usually points to a software setting conflict, and does
not signify a hardware problem.

Running Ping under UNIX
The ping program is typically found in the /etc or/usr/etc directory,
so you must add the appropriate directory to your path, or type the full
path:
/etc/ping <IP address> 64 5
or
/etc/ping <hostname> 64 5
This command tells ping to send 5 packets of 64 bytes each.
The output should look similar to this:
PING hostname: 64 byte packets
64 bytes from 15.4.43.5: icmp_seq=0. time=8. ms
64 bytes from 15.4.43.5: icmp_seq=1. time=4. ms
64 bytes from 15.4.43.5: icmp_seq=2. time=4. ms
64 bytes from 15.4.43.5: icmp_seq=3. time=3. ms
64 bytes from 15.4.43.5: icmp_seq=4. time=3. ms
hostname PING Statistics
5 packets transmitted, 5 packets received, 0% packet loss
round-trip (ms) min/avg/max = 3/4/8
If you do not see any output after about 20 seconds, interrupt the ping
command using ^c (hold down the “Ctrl” key, and press “c”). Once you do
this, the ping program should provide some statistics on how many
packets were sent and received. If the statistics look like
hostname PING Statistics
4 packets transmitted, 0 packets received, 100% packet loss
there is a communications problem. Refer to “Troubleshooting the Initial
Connection” on page 8-3 for troubleshooting help and information.
