echoping
|
|
========
|
|
|
|
echoping **was** a small program to test (approximatively) performances of a remote host by sending it requests such as HTTP requests.
|
|
|
|
echoping is **no longer** maintained. This repository is for
|
|
historical interest only.
|
|
|
|
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:
|
|
|
|
* plugins, so you can extend echoping with any protocol you like and/or use,
|
|
* Supports IPv6 as well as IPv4,
|
|
* Supports IDN (Unicode domain names like café.gennic.net),
|
|
* uses the protocols echo, discard, chargen or HTTP,
|
|
* can use cryptographic connections with HTTP,
|
|
* uses UDP instead of TCP for the protocols which accept it (like echo),
|
|
* can repeat the test and display various measures about it,
|
|
|

Examples of output:

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

|
|
|
|
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 (SmokePing does it).
