Configuring NFS on Fonera 2.0n

Install NFS

opkg install unfs3

Edit hosts

Edit hosts.deny:

echo 'ALL: ALL' > /etc/hosts.deny

Edit hosts.allow:

echo '192.168.1.' > /etc/hosts.allow

Set exports

Edit /etc/exports (with vi and enter):

/tmp/mounts/Disc-A1/music (ro,async,insecure,root_squash,proto=udp,anonuid=65534,anongid=65534)
/tmp/mounts/Disc-A1/videos (ro,async,insecure,root_squash,proto=udp,anonuid=65534,anongid=65534)
/tmp/mounts/Disc-A1/pictures (ro,async,insecure,root_squash,proto=udp,anonuid=65534,anongid=65534)
/tmp/mounts/Disc-A1/my_home (rw,sync,secure,root_squash,proto=tcp,anonuid=65534,anongid=65534)

Start service

Start service:

/etc/init.d/portmap start && sleep 3 && /etc/init.d/unfs3 start

Enable persistence

To enable automatic restart on reboot

/etc/init.d/portmap enable && /etc/init.d/unfs3 enable

Set the following parameters according to your preference:

allow > deny
ro: read only
async: unsafe, no file locking but faster
insecure: allow ports over 1024 to connect
root_squash: remote root is converted to anonuid+anongid
anonuid: server uid of anonymous user
anongid: server gid of anonymous user

! uid’s and gid’s are mapped one to one (possible security risk)

Now for pure awesomeness enable automount* on your client:
Easy as: yum install autofs And add the following too

# /etc/auto.misc #
#
# local entries
fon-svjethoe -fstype=nfs,rw,tcp,rsize=32768,wsize=32768 fonera:/tmp/mounts/Disc-A1/svjethoe
fon-music -fstype=nfs,rsize=32768,wsize=32768 :/tmp/mounts/Disc-A1/music
fon-pictures -fstype=nfs,rsize=32768,wsize=32768 :/tmp/mounts/Disc-A1/pictures
fon-videos -fstype=nfs,rsize=32768,wsize=32768 :/tmp/mounts/Disc-A1/videos
# vpn entries
fon-svjethoe -fstype=nfs,rw,tcp,rsize=32768,wsize=32768 10.8.0.1:/tmp/mounts/Disc-A1/svjethoe
fon-music -fstype=nfs,rsize=32768,wsize=32768 :/tmp/mounts/Disc-A1/music
fon-pictures -fstype=nfs,rsize=32768,wsize=32768 :/tmp/mounts/Disc-A1/pictures
fon-videos -fstype=nfs,rsize=32768,wsize=32768 :/tmp/mounts/Disc-A1/videos

Now the folders will be automatically mounted when accessed (defaults under /misc ->)

• rsize= transfer block size for reads in bytes (=32bytes=max=nfs4 default)\
• wsize= transfer block size for writes in bytes ( “” “””” “”)\
• default rsize+wsize in nfs3= 8 bytes

Just run cd /misc/fon-music and you’re there!
