| Determines the initial set of members given a group name and properties and prints them to stdout. Does not
connect to the group, but - using a minimal stack of UPD/PING or TCP/TCPPING - only sends a FIND_INITIAL_MBRS
down the stack (PING or TCPPING has to be present for this to work) and waits for FIND_INITIAL_MBRS_OK. When
received, the results are printed and then the app terminates.
To connect to any group, it is essential that the groupname given (-group) is the same as the one of the group
and the properties are the same as the bottom 2 layers of the group properties, e.g. if the group properties are:
TCP(start_port=7800):TCPPING(initial_hosts=daddy.nms.fnc.fujitsu.com[7800];port_range=2;timeout=5000;num_initial_members=3;up_thread=true;down_thread=true):pbcast.STABLE(desired_avg_gossip=200000;down_thread=false;up_thread=false):pbcast.NAKACK(down_thread=true;up_thread=true;gc_lag=100;retransmit_timeout=3000):pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;shun=false;print_local_addr=false;down_thread=true;up_thread=true)
,then the stack properties should be:
TCP(start_port=7800):TCPPING(initial_hosts=daddy.nms.fnc.fujitsu.com[7800];port_range=2;timeout=5000;num_initial_members=3)
