I'm trying to communicate between two machines with SPDZ-2 but I have a problem. When I launch in both terminals, the program stops at:
Bound on port 4999

And doesn't advance...
In the other terminal it stucks at "Setting up server with id 0x2"

What is my problem?
prvsousa commented
Some debug indicates to me that:
while (clients.find(id)==clients.end())
data_signal.wait();
The program stucks in this line of the file Networking/ServerSockets.cpp
Any idea?=

You have to make sure that your machines can be reached by the official hostname (as delivered by hostname in a terminal). If ping patriciarvsousa doesn't work, SPDZ won't work either.
prvsousa commented
Yes I can because the communication goes until that point related. I can
make ping to abcd3.joacia3.pt in this case (as presented in the example)

Then you have to set the hostname of the machine accordingly.

I have the hostname in the etc/hosts... The machines have the same name, there are any problem?
mkskeller commented
/etc/hosts is only for hostnames of other machines, the hostname of the local machine has to be set by using the hostname command.
