Sunmanagers,
I have a i86pc NFS client that cannot mount (automount or otherwise) a
shared directory (/export/home) off my NFS server. The client (SunOS
nfsclient 5.10 Generic_118844-20 i86pc i386 i86pc) is set up the same as
the rest of my clients, which are working correctly. The client can
mount other shared directories off other NFS servers. The only
difference is that this client is dual-homed but the interfaces are
physical, not virtual.
nfsclient# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu
8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 192.168.xx.xx netmask ffffff00 broadcast 192.168.xx.255
ether 0:12:3f:20:9:30
e1000g1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 172.20.xx.xx netmask ffffffe0 broadcast 172.20.xx.xxx
ether 0:12:3f:20:9:31
nfsclient's messages file is filled with permission denied messages:
Dec 19 15:25:24 nfsclient nfs: [ID 664466 kern.notice] NFS fsinfo failed
for server nfsserv: error 7 (RPC: Authentication error)
Dec 19 15:25:24 nfsclient automountd[331]: [ID 834250 daemon.error]
Mount of nfsserv:/export/home on /home/nfsserv: Permission denied
When I try to cd into /home/nfsserv, I get a "No such file or directory"
message.
When I try and mount nfsserv:/export/home directly to /mnt or cd to
/net/nfsserv/export I get Permission denied.
My nfs server (SunOS nfsserv 5.8 Generic-108528-24 sun4u sparc SUNW,
Ultra-250) isn't complaining except for the following snoop output I
collected when trying to mount /export/home on the client:
# snoop nfsserv
