[Vserver] Multicast and vserver[edit]

Hello, I tried to make ganglia run on a vserver. This is a monitoring package that uses multicast to publish information about its state. I've found an old message about this setting : http://list.linux-vserver.org/archive/vserver/msg07038.html Without particular precaution, I have the same result : gmond -d2 pthread_attr_init creating cluster hash for 1024 nodes hash_create size = 1024 hash->size is 1031 gmond initialized cluster hash Using interface eth0 g_mcast_socket_bind() error: Cannot assign requested address g_mcast_in() failed: Cannot assign requested address If I add the multicast address in the vserver.conf file (IPROOT="192.168.4.5 239.2.11.71") then I obtain the following : gmond -d2 pthread_attr_init creating cluster hash for 1024 nodes hash_create size = 1024 hash->size is 1031 gmond initialized cluster hash Using interface eth0 mcast listening on 239.2.11.71 8649 XML listening on port 8649 listening thread(s) have been started listening thread(s) have been started cleanup thread has been started gmond could not connect to multicast channel: Invalid argument which is better (I think ;-) but still not working. I know out of my mind of some applications that heavily use multicast (ganglia, cups, openSLP, etc.) and it would be convenient if multicast can be enabled in a vserver. What are the technical difficulties ? Ben -- Benoit des Ligneris Ph. D.
