NFS 客户端

软件包: nfs-utils 描述: 更新 mount.nfs 命令来支持 nfs4 卷。

软件包: kmod-fs-nfs 描述: 启用NFS支持的内核模块

软件包: kmod-fs-nfs-common 描述: NFS文件系统模组

For NFSv4 server → install kmod-fs-nfs-v4 For NFSv3 server → install kmod-fs-nfs-v3

opkg update
opkg install nfs-utils kmod-fs-nfs kmod-fs-nfs-v4 kmod-fs-nfs-v3

警告 !  有些版本没有 librpc . 你可以放心使用 --force-depends 。请注意，若要使用 ''mount -t cifs'', 必须启用 busybox 中的 NFS 挂载支持。
 

mkdir /mnt/remote2
mount.nfs //192.168.2.254/router_main /mnt/remote2 [-rvVwfnh ] [-t version] [-o options]

mount -t nfs 192.168.1.101:/share /mnt/point -o nolock

# To connect using NFSv4
mount -t nfs4 192.168.1.101:/share /mnt/point -o nolock

# 对于支持NFS开箱即用的 Fedora 17+服务器
mount -t nfs 192.168.255.124:/home/karlp/src src -o nfsvers=3 -o nolock

The nolock will disable NFS file locking. If you really need file locking, you must install the portmap package and start the portmap daemon before trying to mount an exported filesystem without the nolock option.

In some revisions mounting is not possible because default disabled in kernel: BUSYBOX_CONFIG_FEATURE_MOUNT_NFS [=n]

Read manpage of mount.nfs

Put it in /etc/fstab.

Append -v to your mount command to see detailed debugging info... i.e.;

mount -t nfs 192.168.1.101:/share /mnt/point -o nolock  -v

Since netfilter will track every connection, if you use MASQUERADING for example, you could disable con-tracking for data connections:

$IPT -t raw -A PREROUTING -i $IF_LAN -s $NET_LAN -p tcp --sport 32777:32780 -j CT --notrack #---------- don't track nfs
$IPT -t raw -A PREROUTING -i $IF_LAN -s $NET_LAN -p udp --sport 32777:32780 -j CT --notrack #---------- don't track nfs
$IPT -t raw -A OUTPUT -o $IF_LAN -d $NET_LAN -p tcp --dport 32777:32780 -j CT --notrack #---------- don't track nfs
$IPT -t raw -A OUTPUT -o $IF_LAN -d $NET_LAN -p udp --dport 32777:32780 -j CT --notrack #---------- don't track nfs

Note this is not the same as for the server, the source and destination ports differ. The INPUT is for when you read from the remote filesystem and the OUTPUT for when you write to it.
