Behavior is described right in the man page. So this seems to be on purpose. -h Specify specific IP addresses to bind to for UDP requests. This option may be specified multiple times and is typically necessary when running on a multi-homed host. If no -h option is specified, rpcbind will bind to INADDR_ANY, which could lead to problems on a multi-homed host due to rpcbind returning a UDP packet from a different IP address than it was sent to. Note that when specifying IP addresses with -h, rpcbind will automatically add 127.0.0.1 and if IPv6 is enabled, ::1 to the list. -- Chuck Lever chuck[dot]lever[at]oracle[dot]com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
