Thank you for the support ! I'm surprised it works for you. I'm using < 3.5
kernels. It should work on multiple computer but it doesn't even work on a
single computer for me. The bug 33753 is interesting too but it doesn't work
with the 1.4 for me and it should be a regression since the 1.5.15.

To be sure we are using the same thing. You should have replaced in the
listener:  
this: local_sin.sin_addr.s_addr = htonl (INADDR_ANY);
with:    local_sin.sin_addr.s_addr = inet_addr(YOUR_INTERFACE_IP);

And in the sender:
this: source_sin.sin_addr.s_addr = htonl (INADDR_ANY);
with:    source_sin.sin_addr.s_addr = inet_addr(YOUR_INTERFACE_IP);

I will make some test with the 3.10 and the wine 1.6-rc2 (I just tested it
quickly on another pc) as soon as possible.
