"echoping" is a small program to test (approximatively) performances
|
|
of a remote host by sending it TCP "echo" (or other protocol, like
|
|
HTTP) packets.
|
|
|
|
To install it, see the INSTALL file. Or type "./configure; make" if
|
|
you're in a hurry :-)
|
|
|
|
To use it, simply:
|
|
|
|
% echoping machine.somewhere.org
|
|
|
|
or use the options before the machine name (see the man page).
|
|
|
|
See the DETAILS file for various traps when benchmarking networks,
|
|
specially with this program
|
|
|
|
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.
|
|
|
|
Current features:
|
|
|
|
- uses the protocols echo, discard, chargen, HTTP (with SSL/TLS if you
|
|
wish), ICP or SMTP,
|
|
- uses UDP instead of TCP for the protocols which accept it (like echo),
|
|
- can repeat the test and display various measures about it,
|
|
- supports IPv6 as well as IPv4,
|
|
- supports IDN (Unicode domain names),
|
|
- supports plugins written by you, to test even more protocols (see PLUGINS),
|
|
- can use T/TCP on systems which support it.
|
|
|
|
Examples of output:
|
|
|
|
(Simple test with 1000 bytes echo TCP packets)
|
|
% echoping -v -s 1000 mycisco

(Testing a Web server with an HTTP request for its home page.)
|
|
% echoping -h / mywww
|
|
Elapsed time: 0.686792 seconds
|
|
|
|
(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.)
