>Description:
When using an IP alias to provide NFS services to a network mountd will reply to requests sent to the alias IP from the main IP on that network:
ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 8192
options=b<RXCSUM,TXCSUM,VLAN_MTU>
inet 172.31.0.19 netmask 0xffffff00 broadcast 172.31.0.255
inet 172.31.0.200 netmask 0xffffffff broadcast 172.31.0.200
ether 00:13:72:5c:89:67
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
Relevant line from client fstab:
172.31.0.200:/cfarm/ports /usr/ports nfs ro 0 0
When the client mounts the file system replies from mountd originate from 172.31.0.19 rather than from 172.31.0.200.
Could this be solved by adding the -h option mountd that is already present in nfsd and rpcbind, so that the bind address of mountd could be specified?
