NFS client

Package: nfs-utils Version: 1.1.6-1 Depends: libwrap, libblkid, libuuid, libevent Size: 33390 Description: Updated mount.nfs command - allows mounting nfs4 volumes Package: kmod-fs-nfs Depends: kernel (=, kmod-fs-nfs-common Size: 86611 Description: Kernel module for NFS support Package: kmod-fs-nfs-common Depends: kernel (= Size: 133604 Description: Common NFS filesystem modules

WARNING: The librpc is missing in some versions. You can safely use -force-depends if it happens to you

Note that to use mount -t cifs, NFS mount support in busybox has to be enabled.


mkdir /mnt/remote2
mount.nfs // /mnt/remote2 [-rvVwfnh ] [-t version] [-o options]
mount -t nfs /mnt/point -o nolock
# For Fedora 17+ servers, which are nfs4 out of the box...
mount -t nfs 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.

Throughput Issues

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.
