====== OpenWrt ======

===== Introduction =====

In January 2006 we acquired an ASUS WL500G deluxe, which is a hardware router which also comes with a builtin 4-port ethernet switch, a wlan accesspoint and - which makes it very interesting - two USB2.0 ports. We reflashed that thing with the [[http://openwrt.org|OpenWrt firmware]], which went without any problems and turned the little device into a full sized linux box.

===== Quicknotes =====

  * Interfaces on ASUS WL500G Deluxe: LAN = vlan0, WAN = vlan0, WIFI = eth1

===== dnsmasq refuses to start =====

  * Symptom: ''Syntax error: network+192.168.1.100''
  * Solution: ''dnsmasq'' expects the dhcp-ip-range to be given as integers, not as ip-adresses, so instead of <code>
nvram set dhcp_start 192.168.0.100
nvram set dhcp_end 192.168.0.200
nvram commit
</code> do a <code>
nvram set dhcp_start 100
nvram set dhcp_end 200
nvram commit
</code> and restart ''dnsmasq'': ''/etc/init.d/S50dnsmasq''

===== Remove bridge between wifi and lan interface =====

  * Add to ''/etc/firewall.user'': <code>
WIFI=$(nvram get wifi_ifname)
iptables -A FORWARD -i $WIFI -o $WAN -j ACCEPT
iptables -A FORWARD -i $WIFI -o $LAN -j ACCEPT
iptables -A FORWARD -i $LAN -o $WIFI -j ACCEPT</code>
  * Set the following in nvram: <code>lan_ifname=vlan0
lan_proto=static
lan_ipaddr=192.168.0.1
lan_netmask=255.255.255.0

wifi_ifname=eth1
wifi_proto=static
wifi_ipaddr=192.168.1.1
wifi_netmask=255.255.255.0
</code> and commit it and reboot.
  * Add to ''/etc/dnsmasq.conf'': <code>
dhcp-range=lan,192.168.0.100,192.168.0.199,2h
dhcp-range=wlan,192.168.1.100,192.168.1.199,2h
</code> and do a ''killall -9 dnsmasq ; /etc/init.d/S50dnsmasq''.

===== HP LaserJet 1000 =====

  * On a standard linux box of your choice: 
    * ''wget http://foo2zjs.rkkda.com/foo2zjs.tar.gz && tar xvfz foo2zjs.tar.gz && cd foo2zjs'' 
    * ''make'' \\ ''./getweb lj1000'' 
    * Copy ''sihp1000.img'' to your router
  * On your router:
    * Install the ''p910nd'' package according to the [[http://wiki.openwrt.org/PrinterSharingHowto#head-11fecdddd08a3ea093c1817213fe4d575120af4e|OpenWRT docs]]: ''ipkg install p910nd''. 
    * Install the ''kmod-usb-printer'' kernel modules: ''ipkg install kmod-usb-printer''
    * Create a new file ''/etc/hotplug.d/usb/hplj1000'': <code bash>#!/bin/sh

FIRMWARE="/data/sihp1000.img"

if [ "$PRODUCT" = "3f0/517/120" ]
then
        if [ "$ACTION" = "add" ]
        then
                logger "Sending firmware to printer..."
                cat $FIRMWARE > /dev/usb/lp0
                logger "done."
        fi
fi
</code> Remember to adjust the firmware location accordingly.
  * Now configure the clients from which you want to print, according to [[http://wiki.openwrt.org/PrinterSharingHowto#head-8cebbb267ff2553eb24c0431d16dfa596e29b081|the OpenWRT docs]]. You're done :-)
