freebsd-ports/net/echoping/pkg-descr

"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.

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) 1997-04-12 17:17:34 +00:00			`"echoping" is a small program to test (approximatively) performances of a`
