我正在尝试让我的NFS服务器允许非root用户安装请求.

服务器：Debian Squeeze,内核2.6.32-5-686

我现在拥有的：root(或sudoes)可以挂载NFS文件系统,但普通用户不能.

为什么我认为这是可能的：

I. Debian服务器(10.18.51.1)

已安装的软件包：nfs-kernel-server,nfs-common,portmap

1)/ etc / exports：

/usr/appl/ 10.18.51.0/24(ro,no_subtree_check)

/usr/private/ 10.18.51.11(rw,sync,no_subtree_check)

2)/ var / lib / nfs / etab

/usr/private 10.18.51.11(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)

/usr/appl 10.18.51.0/24(ro,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)

3)导出文件夹的权限：

$ls -lh -d /usr/appl

drwxr-xr-x 3 root root 4.0K Feb 25 17:16 /usr/appl

$ls -lh -d /usr/private

drwxrwxrwx 4 root root 4.0K Feb 27 12:19 /usr/private

II. Ubuntu客户端(10.18.51.11)

已安装的软件包：nfs-common portmap

$mount 10.18.51.1:/usr/appl /mnt/nfs/appl

mount: only root can do that

尽管/ etc / fstab中有用户标记：

10.18.51.1:/usr/appl /mnt/nfs/appl nfs ro,async,nodev,nosuid,user 0 0

10.18.51.1:/usr/private /mnt/nfs/private nfs rw,rsize=8192,hard,intr,nfsvers=3,tcp,noatime,nodev,async,user 0 0

III. FreeBSD客户端(10.18.51.3)

$cat /etc/rc.conf

...

nfs_client_enable="YES"

$mount 10.18.51.1:/usr/appl /mnt/nfs/appl

[tcp] 10.18.51.1:/usr/appl: Permission denied

...

有趣的是,在按Enter后它打印Permission denied,然后等待一段时间,然后尝试连接到10.18.51.1,然后再次打印Permission denied.我知道有关服务器的连接,因为我在服务器上使用了tcpdump(tcpdump host 10.18.51.3)：

$sudo tcpdump host 10.18.51.3

[sudo] password for sukharevd:

有什么建议？

UPD：解决了一半的问题.我应该用过

mount /mnt/nfs/appl
