echoping

echoping is a small program to approximatively test the performance of a remote host by sending it TCP "echo" packets. It is able to use the following protocols: echo, discard, chargen, HTTP (with SSL if you wish), ICP, and SMTP. It uses UDP instead of TCP for the protocols which accept it (like echo), it can repeat the test and display various statistics, and it can use T/TCP on systems which support it.
