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.
