<!-- ==================== MODULE DESCRIPTION ==================== -->
<h1 class="epydoc">Module TCPController</h1><span class="codelink"><a href="VisionEgg.TCPController-pysrc.html">source code</a></span><br /><br />
<pre class="literalblock">
Allows control of parameter values over the network.
Don't use for realtime control unless you think your network is that
fast and reliable. Also, this code has not been optimized for speed,
and I think it is unwise to attempt to change the value of controllers
in realtime. In other words, do not design an experiment where, on a
remote computer, you have determined that a certain amount of time has
passed, and you require a certain new controller value NOW. In this
case, it would be better to use parameter=eval_str() with an if
statement involving time.
To control parameters over a network, start a server with an instance
of TCPServer. The server spawns an instance of SocketListenController
for each connected socket. (Most commonly you will only want
connection over a single socket.) The instance of
SocketListenController handles all communication for that connection
and serves as a container and (meta) controller for instances of
TCPController.
This module contains ABSOLUTELY NO SECURITY FEATURES, and could easily
allow arbitrary execution of code on your computer. For this reason,
if you use this module, I recommend operating behind a firewall. This
could be an inexpensive "routing switch" used for cable modems, which
would provide the added benefit that your local network would be
isolated. This would elimate all traffic not to or from computers on
the switch and therefore reduce/eliminate packet collisions, decrease
latency, and providing a network performance and reliability. To
address security concerns, you could also write code that implements
IP address checking or other security features.
