What we've got to show is 2 receivers and 1 sender. We will need
receivers running on 2 boxes (now you know why we have 2 VPN
servers!)<br>
<p>I will try later today. I do not know if running two VPN clients
is acceptable, or if they will conflict. Thus I'm hoping that
someone else will start open-dis-python receiver. I know that I
cannot bind the receivers to the the same port on the same
machine. I think we may need to bind the receiver to a multicast
address (how?).<br>
</p>
<p>For defining your protocol (ALP), I suggest xmlpg:</p>
<p><a class="moz-txt-link-freetext" href="https://github.com/open-dis/xmlpg">https://github.com/open-dis/xmlpg</a> (I don't think this is specific
to DIS)</p>
<p>(protocol generator)<br>
</p>
<p>That will save us on implementation for multiple languages. We
could probably write a converter to nodes for a spec.</p>
<p>*Would it be useful to write a X3DUOM to XMLPG converter? I'll
have to think about that!*</p>
<p>I don't think this issue is limited to DIS, and would likely
apply to ALP as well.</p>
<p>I'll look for multicast VPN<br>

i think i can choose any port i want, since no other server is

i *really* think server-less mode with mcast IP addresses

<p>Initially, we should do open-dis-python (found on github).
This is for testing sending and receiving.</p>
<p>I'm trying to get netbeans working, because the only
browser that works is Xj3D, I think.</p>
<p>I don't think that there's servers per se, but I think only
one process can bind to UDP port.</p>
<p>I have switched to port 1194 per your config file. So you
should be seeing traffic on that port now</p>

<p>If you send me the address/host and port of
your VPN, I should be able to run the Linux
client? Not sure at this point. You can
send me your windows client config, and I
should be able to pull host/port out of
that.</p>

We've still got a problem with running the
receiver on a centralized host, but perhaps
with multicast, that is unnecessary?</p>
<p>Did you have any luck connecting to our

Betreff: DIS examples...no hits against
VPN multicast DIS server <br>
We had success with open-dis-python
running the receiver on my openvpn <br>
client machine (with the VPN server and
DIS sender running elsewhere). <br>
When we tried to run the receiver
elsewhere, no luck. <br>
<br>
I was able to modify X3D resources
examples which contained address= to <br>
point to our DIS server, which was
similar to the dis_receiver.py found <br>
in open-dis-python. <br>
<br>
It didn't appear like any of the
examples I tried from X3D resources <br>
examples contacted the DIS receiver. <br>
<br>
<br>
I will try to meet with Christoph V or
Don or someone to figure out <br>
what's going on. I have not delved deep
into the X_ITE codebase yet to <br>
see if DIS is fully implemented. <br>
<br>
<br>
How does one define success with a DIS
webapp? What's the best X3D <br>
browser for DIS? <br>
<br>
