[SGS] LRMP Errors

Networking & Multiplayer
#1

I get one of these:


com.sun.multicast.util.ImpossibleException: null; internal exception is:
        inria.net.lrmp.LrmpException: java.net.SocketException: IP_ADD_MEMBERSHI
P failed (out of hardware filters?)
        at com.sun.multicast.reliable.transport.lrmp.LRMPPacketSocket.<init>(LRM
PPacketSocket.java:106)
        at com.sun.multicast.reliable.transport.lrmp.LRMPTransportProfile.create
RMPacketSocket(LRMPTransportProfile.java:126)

When I try the SGS server out. Doesn’t seem to hurt anything and readme does say multicast errors might turn up. I was just wondering what it was (could it be MS Wndows related?)?.

The annoying bit is I go on to get a recurrent null-pointer exception as the server is running about every second when it tries to access the LRMP stack thats failed to initialise. Anyway I could at least hide this problem?

This is due to LRMP being used to communciate with the DiscoveryManager. We’ve discussed being able to turn that off or re-point it.

In the mean time, your problem is your firewall. It is blocking multicast. Myself, I always turn the WIn32 firewall completely off on my server machine. if you dont want to do that you will have to explore how to enable multicast with the firewall still turned on…
