As promised here is the source code for La Fonera: http://download.fon.com/firmware/fonera … ra.tar.bz2
Please forward suggestions for improvements to iurgi@fon.com

Also, if you like to do Openwrt projects please let us know, we are offering grants for interesting ones!

Status of this package: Experimental

Known Problems: Adhoc+Mastermode does not work perfect, some wifi cards
do not want to cooperate (at least my atheros/madwifi does not see the
Hotspot with kubunu nor do it see the WPA "MyPlace"). A centrino IPW2100
and a Siemens-Atheros-USB (ndiswrapper) work fine. Ad-hoc is fine too now.
You also need to put FF_IP=x.x.x.x in /etc/init.d/S80freifunk currently.

Note: Automatic upgrading from fon is stopped with this pack. You will
notice after a while, that /tmp/.thinclient.sh exists. These following
updates are verified by me and are ok to install. You can use the fonlist
command which is included in ff-fonera-pack to check yourself what's in
an *.fon file (simple tgz with the fon signature). You cal download
these manually and install via Web UI if you like:

Registration bugfix:
  http://download.fon.com/firmware/update … pgrade.fon

Update of the the madwifi driver and other stuff:
  http://download.fon.com/firmware/update … pgrade.fon

PPPoE Update, will not install automatically:
  http://downloads.fon.com/firmware/updat … 3_rev4.fon

Another note: The madwifi update does _not_ fix the current parallel AdHoc+
Master mode probs. You also need a standard Freifunk router with fixed BSSID
in range in order to have AdHoc up and running.

Howto install ff-fonera-pack:

1) You need a linux shell prompt. You can add a serial console. Assemble
   a standard MAX232 serial voltage level adapter (google for "wrt54g serial"
   for soldering tips).

2) The onboard 10-pin header offers access to the command line. Pin1=3,3 Volt,
   Pin2=Ground, Pin6=TX(to PC), Pin8=RX(from PC). Speed 9600,n,8,1.

3) You may remove any configuration + fon updates by issueing "rm -r /jffs/*"
   (+restart by pulling the power plug). This will remove all changes to the
   original firmware (mini_fo overlay files are removed by this).

4) Enter "cd /etc/init.d;mv dropbear S51dropbear;./S51dropbear start" to
   enable the ssh service on the box. Now it is possible to work more
   convenient with "ssh 169.254.255.1" over ethernet connection.

5) Verify internet connectivity by "ping google.com" or so.

6) ipkg install http://olsrexperiment.de/sven-ola/foner … 1_mips.ipk

7) Change ip/wifi config in /etc/init.d/S20madwifi-freifunk using standard "vi"

The ff-fonera-pack will do these changes on the box:

- It installs the shell script variant of the ipkg command and alters the
  /bin/rmdir command. This is a bugfix for the buggy rmdir implementation of
  mini_fo (removes a directory tree while deinstalling ipks even if directory
  is non-empty. Fatal with "rmdir /lib".

- Installs olsrd daemon as well as start scripts to add a new ath2 virtual
  ad-hoc wifi interface. Opens the firewall to let any packets from-mesh
  ip address range through.

- Disables the auto-fon-update mechanism. You need to install upgrades
  manually. Verify "cat /tmp/.thinclient.sh" on a regulary basis to check
  if new FON updates are in the queue. Update is disabled, because it is
  unclear if future updates will be incompat with ff-fonera-pack and I
  personally do not like other people fiddeling with my hardware too.
  You can remove the "#" in the last line of /bin/thinclient if you
  want the autoupdate back.

- FON function (private AP with WPA and public unencrypted AP) should work
  as usual. Configure that stuff with the web UI. It may be necessary
  to configure a fixed channel (madwifi does support several virtual Wifi
  interfaces, but they all share the same channel setting).

Attention: This will open your internet connection to all users in the
mesh. You have no choice currently besides your own hacks of course. I may
add policy routing statements in future versions of this pack in order to
offer this choice (wether you will only allow OLSR mesh members to route
through your box or if you also want to offer your inet to mesh members
for free). I will not add any FON registration for mesh members - the FON
stuff is bound to the hotspot function and the chillispot software is not
compat with routing too.

!!! No warranties, no complaints. This is experimental stuff. If you want to
remove the ff-fonera-pack, issue "rm -r /jffs/*" and reboot by pulling the
plug. This restores the standard FON router function. !!!
