<P>"echoping" is a small program to test (approximatively) performances of a
|
|
remote host by sending it TCP "echo" (or other protocol) packets.
|
|
|
|
<P>To install it, see the INSTALL file. Or type "make" if you're in a
|
|
hurry :-) <A
|
|
HREF="ftp://ftp.internatif.org/pub/unix/echoping">Download</A>, if you
|
|
wish. (Or you may prefer access the latest developments <A
|
|
HREF="http://sourceforge.net/cvs/?group_id=4581">via CVS</A>: the
|
|
module is named "SRC".) You may be interested in <A HREF="http://sourceforge.net/project/?group_id=4581">SourceForge's page
|
|
about echoping</A>, with the bug reports, etc.
|
|
|
|
<P>To use it, simply:
|
|
|
|
<PRE>
|
|
% echoping machine.somewhere.org
|
|
</PRE>
|
|
|
|
<P>or use the options before the machine name (see the man page).
|
|
|
|
<P>See the <A HREF="details.html">DETAILS</A> file for various traps when benchmarking networks,
|
|
specially with this program.
|
|
|
|
<P>In any case, be polite: don't bother the remote host with many repeated
|
|
requests, especially with large size. Ask for permission if you often
|
|
test hosts which aren't yours.
|
|
|
|
<P>Current features:
|
|
|
|
<UL>
|
|
<LI>uses the protocols echo, discard, chargen or HTTP,
|
|
<LI>uses UDP instead of TCP for the protocols which accept it (like echo),
|
|
<LI>can repeat the test and display various measures about it,
|
|
<LI>can use T/TCP on systems which support it.

<P>The exit status is set if there is any problem, so you can use echoping
|
|
to test repeatedly a Web server, to be sure it runs fine. Or you can
|
|
display statistics like <A HREF="http://monitor.internatif.org/web.html">at Internatif</A>.

|
<P>To do for a future version:
|
|
|
|
<UL>
|
|
<LI>display other calculations such as standard deviation
|
|
<LI>fix the bugs (everlasting aim)
