sorry, didn't make it clear before : the 5400 port is absolutely ok, problem comes if you try to run pd on server with firewall, closed ports, etc. it is simply not enough if i leave only 5400 port open. pd (sometimes) does not start.

for unknown reason it *mostly* works after restarting system. perhaps it has something to do with iptables rules. thanks
