Re: Run Arch Raspberry Pi Piratebox over both eth0 and wlan

Setting the bridge up is pretty difficult. I prepared the configuration files for LibraryBox but never released it.

Maybe you should make a backup of the SDCard before starting!

Technically, you need to do the following steps:

Create bridge interface

Create the following file /etc/netctl/piratebox_bridge

Description="General bridge interface for PirateBox"
Connection=bridge
Interface=br0
BindsToInterfaces=()
ForceConnect=yes
#Enabling DHCP stuff
SkipForwardingDelay=yes

IP=static

Address=(192.168.1.1/24)
IP6=no

Enable that new bridge interface:

sudo netctl enable piratebox_bridge

Next step is to make sure that the ethernet adapter is attached to the bridge. In fact, this could be done much easier (you won't need to have a separate piratebox_bridge config.. you will see later why).

Create the file /etc/netctl/lan_piratebox_bridge

Description="Includes the Ethernet device per default to the PirateBox-Bridge"
Connection=ethernet
Interface=eth0
BindsToInterfaces=(eth0)

ExecUpPost="brctl addif br0 eth0"
ExecDownPre="brctl delif br0 eth0"

IP=no
IP6=no
SkipNoCarrier=yes

and a backup file to get internet connection again: /etc/netctl/lan_dhcp

Description="Generic profile for lan with DHCP"
Connection=ethernet
Interface=eth0
IP=dhcp
ForceConnect=yes

After that, you need to change the piratebox scripts config:

	cd /opt/piratebox
	sed 's|DO_IFCONFIG="yes"|DO_IFCONFIG="no"|' -i conf/piratebox.conf
	sed 's|USE_DNSMASQ="no"|USE_DNSMASQ="yes"|' -i conf/piratebox.conf
	sed 's|DNSMASQ_INTERFACE="wlan0"|DNSMASQ_INTERFACE="br0"|' -i conf/piratebox.conf
	sed 's|BRIDGE="br-lan"|BRIDGE="br0"|' -i conf/piratebox.conf
	sed 's:NET=192.168.77:NET=192.168.1:'  -i conf/piratebox.conf
        sed 's|DO_BRIDGE="no"|DO_BRIDGE="yes"|' -i conf/piratebox.conf

The following changes will do the following:

* Don't setup the IP on br0
* Bring up dnsmasq listening on br0 interface
* Attach Wifi card to bridge after it is online

Next step is to attach ethernet port to the bridge:

netctl disable lan_dhcp
netctl enable  lan_piratebox_bridge

Now you can attach clients via ethernet cable and they will get an IP from the PirateBox

All changes will be applied after a reboot.

---

If you want to make internet possible again run the following to commands and perform a reboot:

netctl disable  lan_piratebox_bridge
netctl enable lan_dhcp

---

Attention: PirateBox will be available under the IP 192.168.1.1 after that change.

I am guessing it is working like that, at least that is what I can remember.

Let me know if that worked out.
