ok, on the HP's, type "which ping"
                 and up should pop:  /etc/ping

on the sun's (they have to be different):  /usr/sbin/ping
        it's not in the user's path.... 

and of course, it won't work the same,
on the sun's if you say /usr/sbin/ping it'll come back with a reply that
suchandsuchhost is alive.  Useful information isn't it? 

so you have to feed it:   /usr/sbin/ping -s hostname 64 5

you can alias ping in your shell so you don't have to type the full path,
or add it to your path... this is a sun issue 

Anyway, on either system you can type:  "man ping"  to gather useful
information.  (we'll sorta useful)

the -s hostname tells it to send more than one packet, the 64 is the default
packet size, you can vary it, and 5 is the count, number of times you ping.

Ctrl C usually breaks you out, if not, the delete key might.  (terminal
settings get loused up over "flaky" networks I've found...
