Peter Wemm 358c5baa72 echoping is a damn useful tool for checking reachability other than
via icmp status, eg: tcp or udp.  It speaks http as well, so it can
"ping" a http server or a http proxy cache to make sure it's operating
and not wedged.  (Nearly all of our system lockups are not detected
by icmp pings)

"echoping" is a small program to test (approximatively) performances of a
remote host by sending it TCP "echo" (or other protocol) packets.
- uses the protocols echo, discard, chargen or HTTP,
- uses UDP instead of TCP for the protocols which accept it (like echo),
- can repeat the test and display various measures about it,
- can use T/TCP on systems which support it.
It's useful for checking that http servers are running and not wedged.
