If you use pre-launched render clients (pc2), you have to start them before the application so they are found during initialization.

This should also work, though in the reverse order. And you should not start a second process on pc1 as it is an appNode, i.e., the application process is also the render client.

OK.

I think I have badly explain the test I have done.
When I have written:

> I have also tried on pc 1:
> -> eqPly.exe --eq-config .\configs\2-node_test.eqc
> -> eqPly.exe

I haven't launched the 2 applications at the same time. I have juste tried
different arguments.

So what I have done is :

-First test:
PC1:
-> First to be start: eqserver.exe .\configs\2-node_test.eqc
-> Second to be start :eqPly.exe --eq-config .\configs\2-node_test.eqc
--eq-listen 192.168.0.1:4242
PC2:
-> Third to be start: eqPly.exe --eq-config .\configs\2-node_test.eqc
--eq-client --eq-listen 192.168.0.1:4242

Second test:
PC1:
-> First to be start: eqserver.exe .\configs\2-node_test.eqc
-> Second to be start eqPly.exe --eq-config .\configs\2-node_test.eqc
--eq-listen 192.168.0.1:4242
PC2:
-> Third to be start: eqPly.exe --eq-config .\configs\2-node_test.eqc

Third Test:
PC1:
-> First to be start: eqserver.exe .\configs\2-node_test.eqc
-> Second to be start: eqPly.exe --eq-config .\configs\2-node_test.eqc
--eq-listen 192.168.0.1:4242
PC2:
-> Third to be start: eqPly.exe

So what is the good way ?
Is-it to start PC2 first and then eqPly on pc 1 and then the server ?

And, what do you mean by pre-launched render clients ? Is there something
dealing with this in the programmer guide ?

Thank you.

server
PC2 (aka the render clients)
PC1

OR

PC2
PC1 using --eq-config

Yes. When launched with --eq-client, an Equalizer application becomes a render client. It's prelaunched since you're not using the server (ssh) launch mechanism.

HTH,

Stefan.

It should be so simple but still does not work.

So, I am still using the config file describe above.

1 - On PC1 (192.168.0.1), I start the server: eqserver.exe --eq-config
.\configs\2-node_test.eqc

2- Then, On PC2 (192.168.0.2), I start the render client: eqPly.exe
--eq-client --eq-listen 192.168.0.1:4242

3 - Finally On PC1, I start eqply : eqply.exe --eq-config
.\configs\2-node_test.eqc

I have an error message on PC2:

E:\osgScaleViewer>eqPly.exe --eq-client --eq-listen 192.168.0.1:4242

I have seen some ssh call but I have no ssh installed on my two windows
machine. Should I have ssh installed ? And, which one ?

What are the good arguments lines for eqserver and eqPly for PC1 and PC2.
Because, I think that it can comes from this.

Thank you.

You can't listen on ip .0.1 on machine .0.2


Hth,

Stefan.

But why I can't listen 0.1 on 0.2. machine 0.1 has the server and has the
appnode. That's why I want to listen 0.1. But I should be wrong or I have
not well read the programmer guide.

So, what are the default command lines to test Equalizer on two pc ? :)

Thank you for your help.

Hello,

I continued to test (using the Programmer's Guide), but impossible to run
eqPly on one machine with eqServer on an other machine.
I have tested with just a single node.

So if there is a simple tutorial that explains how to use (with good
explanations) with 1 or 2 clients and a server that would be really great.

Thank you.

My time for free support is limited. I told you were your mistake is.

A basic knowledge of networking is assumed on this list, otherwise you're free to purchase commercial support where we'll be happy to explain it in as much detail as needed. Otherwise I suggest reading up on the basics of TCP sockets. Other people on this list have figured it out with much less support, maybe you're lucky and someone has more time at their hands.

Cheers,

Stefan.

Hello,

I had seen my error about the bas listenning and I have knowleged about
networking.

I'm just pointing out that the documentation on the use (not the development
documentation that seems very complete) Equalizer examples is very light.
If there was a well documented tutorial (a starter guide) on using, for
example, eqPly rendering a given file with 2 nodes, using eqServer, know the
arguement that can be used (--eq-client, --eq-listen, --eq-config) I will
not make you waste your time.

May be this docuementation exists and I have not find it (I have downloaded
the EqualizerGuide, the programmation guide and Equalizer pdf).

I would really like to use Equalizer examples in order to see if it could
be used for our project but it 's not so obvious.

Thank you for your attention and sorry for the inconvenience.

The command line option is -m. The ply file only needs to be on the application node.

Hi,
Here's what I have done. I hope it is well done.

I use the 2-nodes.eqc file and I have modified it.
For the server: type TCPIP port 4141 hostname "192.168.0.1"
For the AppNode: type TCPIP port 4242 hostname "192.168.0.1"
For the Node: type TCPIP port 4343 hostname "192.168.0.2"

Then here the order of my execution:

1/ On 192.168.0.2 Computer:
> eqPly.exe --eq-listen 192.168.0.2:4343 --eq-server 192.168.0.1:4141
> --eq-client

1: On 192.168.0.1
> eqServer.exe ..\2-nodes.eqc

3: On 192.168.0.1
> eqPly.exe --eq-server 192.168.0.1:4141 --eq-listen 192.168.0.1:4242

Then applications starts. Hope it could help.

But, I don't know how to use a ply file and if the ply file should be on
both computers.
