Hello,
I'm trying to set up two computers to communicate via OSC. The two
computers will be running Csound and I would like one of them to be
able to send OSC messages to the other via the already existent
network. How do you achieve this? I'm not a network guru but I've been
trying to do it using port forwarding via ssh but without any success
(and I'm not even sure if using ssh is the right thing to do). Is
there anyone in the list doing this kind of thing?
Thanks!
Hector

I hope I am not stating the obvious here, but usually OSC is sent over
UDP and, usually, whereever you define the UDP port the OSC packets are
sent to, you should also be able to define the remote host's IP
address/its domain name. Of course, this depends on the software you're
using.

I think more info might be needed for people to help with this (unless
they make a good guess!).
Assuming your network is IP over ethernet:
1 Are the computers on the same subnet?
2 If not, is traffic routable between them (do you have a router)?
3 Are there any port blocking/forwarding devices between the computers?
Firewalls? Proxy servers?
4 Is there any firewall/port blocking software on the individual
computers
5 Can they `ping' each other?

Thanks for your replies.
The network set up is quite simple. Both computers are connected to a
router (one wireless and the other wired) and the router has internet
access. Both computers are able to communicate (I do rsync file
transfers often) and I'm also able to ssh from one to the other. I
finally got two instances of Csound running on each computer to
communicate using OSC using the built in OSC opcodes. My only problem
now is getting wiiosc running in one computer to communicate with
Csound on the other. Wiiosc is set to output on port 57120 and I was
trying to forward that port to the other computer using ssh (57120 in
the wiiosc host to 57120 in the Csound client: ssh -v -L
57120:192.168.2.10:57120 192.168.2.10 ). The ssh session starts fine
but for some reason I don't get anything coming in the clients' 57120
port. The firewall in the client has that port open.
Anyways, I just would like to learn how to do this properly but I
guess what I'm lacking here is networking knowledge and this might not
be the right list to discuss about it.
Cheers,
Hector

The problem is that wiiosc uses localhost implicitly. It would be close
to trivial to add another option to wiiosc so that you can define a
remote host instead. I don't have the time at the moment, sorry. As a
quick hack you could change line 228 in wiiosc.c
t = lo_address_new(NULL, outport); // change later to use other host
and replace the NULL by the remote host's IP address:
t = lo_address_new("192.168.2.10", outport);
and recompile.

Thanks a lot! I'll do what you suggested.

Prompted by this discussion I just released version 0.3 on my website which
makes the IP address configurable on startup.
Get the new version from:
