Hi,
I recently upgraded a system from 7.x to 8.0-RC1 (well, got new guts for=20
it and copied the data over..) and I am having trouble getting NFS to=20
work.
I have re0 like so
re0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0=
=20
mtu 1500
=20
options=3D389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,=
WOL_MCAST,WOL_MAGIC>
ether 00:24:1d:d1:92:cc
inet 10.0.2.1 netmask 0xffffff00 broadcast 10.0.2.255
inet 10.0.2.3 netmask 0xffffffff broadcast 10.0.2.3
inet 10.0.2.4 netmask 0xffffffff broadcast 10.0.2.4
inet 10.0.2.7 netmask 0xffffffff broadcast 10.0.2.7
media: Ethernet autoselect (1000baseT <full-duplex>)
status: active
and when I try and NFS mount something on 10.0.2.7 I see that the reply=20
comes from the wrong address (10.0.2.1). ie from wireshark..
7 0.801704 10.0.2.1 10.0.2.103 NFS V3 NULL Reply (Call In 6)
8 0.802742 10.0.2.103 10.0.2.1 ICMP Destination unreachable (Port=20
unreachable)
Interestingly Linux works OK, but perhaps it specifically allows it some=20
how?
I can work around this by using -h to bind to 10.0.2.7 though, which is=20
what I did on 7.x. I was wondering if there was a "correct" solution=20
though.
=2D-=20
