1. switch to use -publicIp instead of -publicUrl 2. -ip can be empty. It will listen to all available interfaces. 3. For "weed master", these options are changed: -masterPort => -master.port -peers => -master.peers -mdir => -master.dir -volumeSizeLimitMB => -master.volumeSizeLimitMB -conf => -master.conf -defaultReplicaPlacement => -master.defaultReplicaPlacement -port => -volume.port -max => -volume.max
