- some machines (most notably SGIs, and now, IBMs) respond to a "ping -R"
- `properly` many others (most notably SUNS), don't have the
- slightest idea what to do with a 'record-route' ping packet.
- still others ignore the 'record route' and simply respond like it is a
- normal ICMP echo packet.
-
- basically, you just have to ping a machine that knows how to respond
- to a '-R' packet. You also get better responses when you ping machines
- that are quite remote- What it tries so do is rocord which routers
- the packet has to go thru to get out and back..
