<h3>3proxy Traffic Correction Plugin</h3>
|
|
3proxy logs and counts traffic at the application level, while providers usually do
|
|
so at the network or link level. This is significant if you use 3proxy for billing,
|
|
especially in cases where network packets are small, e.g., online games.
|
|
<p>
|
|
This plugin attempts to correct 3proxy's computations to approximate network or
|
|
link-level traffic by using either fixed coefficients by port number or
|
|
by attempting to predict the number and sizes of network packets.
|
|
</p><h4>Usage:</h4>
|
|
<ol>
|
|
<li>Extract TrafficPlugin.dll to the same folder as the 3proxy executable.
|
|
</li><li>Start the plugin in 3proxy.cfg with:
|
|
<pre>plugin TrafficPlugin.dll start
|
|
</pre>
|
|
</li><li>Add correction rules:
|
|
<br>
|
|
FOR FIXED COEFFICIENTS MODE:
|
|
<pre>trafcorrect m <service> <target port> <coefficient>
|
|
</pre>
|
|
where <service> - one of proxy, socks4, socks45, socks5, tcppm, udppm, pop3p; * matches "any".
|
|
<br> <target port> - target port; * matches any
|
|
<br> <coefficient> - coefficient to multiply traffic for this port.
|
|
<br>
|
|
FOR PACKET HEADER PREDICTION MODE:
|
|
<pre>trafcorrect p <service> <tcp/udp> <target port> [empty packet size]
|
|
</pre>
|
|
tcp or udp - transport-level protocol to apply the rule to
|
|
<br>
|
|
empty packet size - average size of an "empty" packet, i.e., the sum of average network/transport headers.
|
|
You can use a network sniffer such as Ethereal to discover it. Usually, the packet size
|
|
is 42 for UDP and
|
|
<br>Modes can be mixed.
|
|
<br>The plugin creates a list of rules; the first matching rule will be applied.
|
|
</li></ol>
|
|
For any mode, the plugin approximates traffic; the logged or counted amount is not exact.
|
|
<h4>Example:</h4>
|
|
<pre>plugin "TrafficPlugin.dll" start
|
|
trafcorrect m socks5 6112 4.5
|
|
trafcorrect m socks5 * 1.1
|
|
</pre>
|
|
Wrong usage:
|
|
<pre>trafcorrect m socks5 * 1.1
|
|
trafcorrect m socks5 6112 4.5
|
|
</pre>
|
|
The second rule will never be applied.
|
|
