I have an AIR app that need to communicate via OSC with a remote server.
I'm somewhat confused by the differences between this 'Flosc' AS3 library
https://code.google.com/p/flosc/
and TUIO AS3
https://code.google.com/p/tuio-as3/
since they both allow OSC communication.
Can anyone shed some light on this? Is TUIOAs3 simply more powerful?
I see the last updates have been around 2011 on both.
I think FLOSC is slighly older and relies on running a UDP Server for OSC connectivity which then is bridged to as3 via the Socket class(which is TCP)
This bridge is the java application available on the FLOSC repository download list. On OSX they recommend Memo's udp-tcp-bridge.
tuio-as3 includes OSC support which you need and the nice thing about it is that it can also make use of AIR's udp functionality, so you won't need the java or c++ UDP to TCP Bridge.(the simpler the better, you'll have to worry about 2 apps being configured properly, not 3 as you would with FLOSC)
I'd recommend tuio-as3 if you're not sure, especially since you already have a basic as3 example from last year (which I hope was helpful).

I'm pretty new to unix operating systems. I'm running CentOS 6.5, and I need to run 1 (or more ideally) instances of Flash Player continually in the background, I've no idea how to do this.
The reason is because in Flash I'm using the RTMFP protocol to send data between clients P2P, and it would be useful for me to have a few test clients running on my server all the time.
How would I go about doing this? The flash program needs to be visually navigated through its menus to get it into the state required. Currently I'm just using putty, what can I install to get a GUI to do this, and how might I go about getting Flash Player (10.1 up) to work?
Thanks a lot!
I think I have an idea what you're trying to do. To clarify, you want to have several flash applications running in browsers or via a flash player to act as test users to test your RTMFP protocol?
If this is the case, use VNC (something like running multiple instances of x11vnc on different ports) to log into several GUI accounts on your system and run the application (Linux is multiuser by default). You can close out the VNC without ending your session. This should work for what I think you're trying to do.
Hope this helps.
How do I run OpenERP Web 6.1 on a different machine than OpenERP server?
In 6.0 this was easy, there were 2 config files and 2 servers (server and "web client") and they communicated over TCP/IP.
I am not sure how to setup something similar for 6.1.
I was not able to find helpful documentation on this subject. Do they still communicate over TCP/IP? How do I configure the "web client" to use a different server machine? I would like to understand the new concept here.
tl;dr answer
It's meant only for debugging, but you can.
Use the openerp-web startup script that is included in the openerp-web project, which you can install from the source. There's no separate installer for it, as it's not meant for production. You can pass parameters to set the remote OpenERP server to connect to, e.g. --server-host, --server-port, etc. Use --help to see the options.
Long answer
OpenERP 6.1 comes with a series of architectural changes that allow:
running many OpenERP server processes in parallel, thanks to improved statelessness. This makes distributed deployment a breeze, and gives load-balancing/fail-over/high-availability capabilities. It also allows OpenERP to benefit from multi-processor/multi-core hardware.
deploying the web interface as a regular OpenERP module, relieving you from having to deploy and maintain two separate server processes. When it runs embedded the web client can also make direct Python calls to the server API, avoiding unnecessary RPC marshalling, for an extra performance boost.
This change is explained in greater details in this presentation, along with all the technical reasons behind it.
A standalone mode is still available for the web client with the openerp-web script provided in the openerp-web project, but it is meant for debugging purposes rather than production. It runs in mono-thread mode by default (see the --multi-thread startup parameter), in order to serialize all RPC calls and make debugging easier. In addition to being slower, this mode will also break all modules that have a web part, unless all regular OpenERP addons are also copied in the --addons-path of the web process. And even then, some will be broken because they may still partially depend on the embedded mode.
Now if you were simply looking for a distributed deployment model, stop looking: just run multiple OpenERP (server) processes with the full stack. Have a look at the presentation mentioned above to get started with Gunicorn, WSGI, etc.
Note: Due to these severe limitations and its relative uselessness (vs maintenance cost), the standalone mode for the web client has been completely removed (see rev, 3200 on launchpad) in OpenERP 7.0.
Is it possible to open a port using Native Client that other browsers can connect to? Like a browser to browser connection?
In general, no. NaCl does not allow programs to open sockets directly (that would be a security problem). It is intended that NaCl/Pepper applications have the same general capabilities as Javascript applications; so something like WebSockets (connection back to the server) would be supported, but not directly opening files or sockets on the client machine. There's some work going on to have a P2P style networking in HTML5 (e.g. http://www.w3.org/TR/2008/WD-html5-20080122/#peer-to-peer) which would likely get Pepper support as well, but I don't know what the status of that is.
The only way to get P2P connection in browser is through WebRTC. If NaCl allows to use WebRTC (though Pepper API or whatever) then the only thing you need besides implementation is broker server that will connect clients with each other. See PeerJS for some info.
Two connected qustions
I understand that non HTML5 browser can connect to websockets using flash.
https://github.com/gimite/web-socket-js
1. However is there an implementation of websockets for flash inside flash?
2. If I were to use normal flash sockets, would the sockets work if there were multiple instances of the flash file running on a local network connecting to an external socket server. Would the messages intended for one instance be forwarded to all instances
Here is a Flash implementation for use in Flash itself: https://github.com/y8/websocket-as
I'm not sure what you are asking but it sounds more like a question about the WebSockets server application and that completely depends on your application.
1) How would I connect through a proxy if I am using the Socket class to connect to a server?
2) If I am running my Flex application through Flash Player in a webbrowser and my webbrowser is configured to use a proxy, does the socket connection go through the proxy automatically?
Ideally, I would like to not have to depend on the web browser's settings, and be able to programmatically proxy the connection from my own code. By supporting proxies directly, I can compile it as a desktop AIR application and still support proxying the connection. Additionally, there may be cases where more than one socket connection will need to be created to different proxies.
Using Action Script 3 in Flex Builder 3.
Thanks.
You may not be able to do this with the vanilla Socket class, but check out this post by Christian Cantrell of Adobe (Google cache version) about a specialized socket class he wrote to allow "TCP socket connections through HTTP proxies in accordance with RFC 2817". His class, the winningly-named RFC2817Socket.as (github), is used by Open Flash Chart. As Christian notes in his post, there are some caveats and it may not work for you if your server doesn't support RFC 2817, or if there are certain other conditions which aren't met.
Note that on Windows, the Flash Player uses IE's proxy settings and ignores the settings of the actual browser you're using.
I've had a look and it doesn't seem possible to do exactly what you want to do. If you have control of a server you can route requests through a server yourself ... and Adobe has examples of this using their Flex Data Access services (BlazeDS and LiveCycle) to go through a proxy. Then again if you control your own server you can get it to proxy anyway you like ...
But I'm afraid there doesn't seem to be anyway to directly set a proxy on the client side using ActionScript.
As for Flash respecting the browsers proxy, I can't say I know from first-hand experience but the evidence from searching isn't good. Here is an article that claims flash won't use your browsers proxy setting for SOCKS on Linux and suggests you need to alter your iptables. There is also this adobe bug report suggesting it doesn't work for rtmp connections at least. Other anecdotal evidence suggests that it works sometimes (for HTTP requests) for some browsers.
So if you need to guarantee that a connection goes through a proxy it looks like you'll need to route your requests through a server and proxy from there.
You can't do that with a regular HTTP or SOCKS proxy. Flex shares browser's connection settings.
But you still can bypass that by using what they call PHP Proxy, basically a website which downloads another websites and forwards the result to you.
