# OpenWrt - How to set NFS [on LAN]

Goal: Share videos/music on a network with an OpenWrt router [read only, anonym, UTF8 characters in file names too, router runs 24h a day, clients always connected]. Kamikaze 8.09.

On the router [if the shared folder is "/mnt/hdd/megosztas/" ]

#!/bin/ash mkdir -p /mnt/hdd/megosztas/ chmod 555 -R /mnt/hdd/megosztas/ opkg update && opkg install unfs3 echo '/mnt/hdd/megosztas/ 192.168.1.0/255.255.255.0(ro)' >> /etc/exports /etc/init.d/unfs3 enable echo '#!/bin/sh /etc/rc.common # Copyright (C) 2006 OpenWrt.org START=50 start() { /etc/init.d/portmap restart /usr/sbin/unfsd } stop() { killall unfsd } restart() { stop sleep 1 start }' > /etc/init.d/unfs3 sync sleep 60 /etc/init.d/portmap stop /etc/init.d/unfs3 restart

Client side [NFS related firewall settings]

#!/bin/bash IPTABLES=$(which iptables) $IPTABLES -A INPUT -i lo -s 127.0.0.1 -p udp --dport 111 -j ACCEPT $IPTABLES -A INPUT -i lo -s 127.0.0.1 -p tcp --dport 111 -j ACCEPT $IPTABLES -A OUTPUT -p tcp -m multiport --dport 111,2049 -j ACCEPT $IPTABLES -A OUTPUT -p udp -m multiport --dport 111,2049 -j ACCEPT

Client side

#!/bin/bash FELHNEV=$(w | awk '/x-session/ && /tty/ {print $1}') mkdir -p /home/$FELHNEV/Desktop/Megosztas/ mount -vvv -t nfs 192.168.1.1:/mnt/hdd/megosztas/ /home/$FELHNEV/Desktop/Megosztas/ -o ro,noexec,nosuid,nodev,noatime,nolock,nfsvers=3

Client side - fstab

#!/bin/bash FELHNEV=$(w | awk '/x-session/ && /tty/ {print $1}') mkdir -p /home/$FELHNEV/Desktop/Megosztas/ echo "192.168.1.1:/mnt/hdd/megosztas/ /home/$FELHNEV/Desktop/Megosztas/ nfs ro,noexec,nosuid,nodev,noatime,nolock,nfsvers=3 0 0" >> /etc/fstab mount -a

ui.: boccs az angol miatt, gyorsabb volt így
ui2.: A lazy unmount hasznos lehet egy esetleges ro NFS meghajtó lecsatoláskor: "umount -l /home/valaki/Desktop/Megosztas", miszerint aranyos dolgok történhetnek, ha nincs kapcsolat a routerrel.. :)
