You may want to check out echoping in the /usr/ports/net collection. According to the docs: "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. Haven't tried it myself. --Mark -- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
