FLASHING

Mac OS X

Since EasyFlash isn't available for Max OS X, we do this manually (FON2200 + ethernet only):

1. Set IP address of your Mac:

sudo ifconfig en0 192.168.1.254

antifuchs says: this does not work reliably on Leopard. What does work is: In Network.prefpane, Make a new network location, make inactive every device except ethernet; set ethernet config to "Manual", configure IP address 192.168.1.254. Then select that location as your current location.

2. Enable tftp

Get TFTPServer, point it to the directory that contains the firmware; it needs to be world-read/writable; you can let that program fix permissions for you.

3. Copy OpenWRT files to tftp dir:

These files are typically what you want to use:

• openwrt-atheros-2.6-vmlinux.lzma
• openwrt-atheros-2.6-root.squashfs

4. Upload the firmware

Two methods here: The lazy approach, and flashing it manually. I recommend doing it by hand at least once to be able to debug the lazy approach if it goes wrong.

Flashing manually

Get access to RedBoot

See also http://forum.openwrt.org/viewtopic.php?pid=63402.

echo -e "\003" > break

fonera an den strom, wenn das 2te led zu blinken beginnt:

nc -vvv 192.168.1.254 9000 < break;

danach ctrl+c

telnet 192.168.1.254 9000

-> You should now have a "RedBoot>" prompt. If not, rinse and repeat.

Flash new kernel and filesystem images in RedBoot:

In RedBoot (assuming you configured the machine with the tftp server to 192.168.1.254):

fis init
load -r -b 0x80041000 openwrt-atheros-2.6-vmlinux.lzma
fis create -e 0x80041000 -r 0x80041000 vmlinux.bin.l7
load -r -b 0x80041000 openwrt-atheros-2.6-root.squashfs
fis create -l 0x06F0000 rootfs

Reboot

You are now where EasyFlash ends. Wait for the boot to finish and telnet to 192.168.1.1 and set a root password.

Flashing automatically (the lazy approach)

Get this expect script (written by Antifuchs and Marius): https://whatever.metalab.at/user/kintel/fonera/flashit.expect

Usage:
1. Start script: ./flashit.expect
Optionally, you can give kernel and squashfs files as parameters if they don't have the default filenames 2. Connect and power up the Fonera
3. When you see stuff happening, go for lunch.<br/

When the script exits (and you see no error message), you can safely reboot the box and telnet to 192.168.1.1

Windows/Linux (easyflash):

• Windows: ap51-flash-fonera-gui-1.0-38.exe 18-Dec-2007 19:12    3.3M

Passendes Tool runterladen.

• openwrt-atheros-2.6-vmlinux.lzma 30-Sep-2007 20:16    768K

die beiden runterladen.

Jetzt kommts..

1. Linux/Unix

     sudo ifconfig eth0 192.168.1.254

   Vista

     netsh interface ipv4 set address "LAN-Verbindung" static 192.168.1.254 255.255.255.0 192.168.1.1

2. Fonera mit Ethernet-Patchkabel an eth0 anstecken.
3. Linux/Unix

     ./ap51-flash-fonera-1.0-38 eth0 openwrt-atheros-2.6-root.jffs2-64k  openwrt-atheros-2.6-vmlinux.lzma

   unter Windows ap51-flash-fonera-gui-1.0-38.exe als Administrator ausführen
4. Strom an den Fonera anstecken

Der Fonera schickt nun beim hochfahren einen ARP request raus, das Flashtool wartet darauf und tut dann seine Magie. Der ganze Flashvorgang dauert rund _15_ Minuten. Zuerst sieht man die IP vom Router Dann steht da was von

Loading RootFS ..
Writing RootFS..  (10 Minuten)
Loading Kernel ..
Writing Kernel.. 
Rebooting Device..

Fertig.

Danach hat der Fonero die IP 192.168.1.1 und ist über TELNET erreichbar. Happy hacking.

set password after flashing

telnet 192.168.1.1
passwd
*****
*****
exit

ssh root@192.168.1.1
yes
*****

note: after flashing, the fingerprint of the router changes. in that case you can delete the known-hosts file from ssh:

rm ~/.ssh/known_hosts
ssh root@192.168.1.1
yes
*****

On Windows you can use PuTTY for the SSH connection.

CONFIGURATION

default network configuration files

file	description
/etc/ethers	specifying static IP addresses via DHCP
/etc/dnsmasq.conf	configures DNS masquerading
/etc/hosts	maps IP-address to hostname
/etc/networks	maps network addresses to network name
/etc/protocols	maps protocol to port number; see IANA for a complete list
/etc/config/dhcp	configures dhcp server
/etc/config/dropbear	configures ssh
/etc/config/firewall	configures firewall
/etc/config/network	configures network interfaces
/etc/config/system
/etc/config/wireless	configures wireless lan adapter

/etc/ethers

This file maps a given MAC-address to an IPv4-Address via DHCP. Example:

# desktop
xx:xx:xx:xx:xx:xx 192.168.1.10
# another desktop
xx:xx:xx:xx:xx:xx 192.168.1.20
# laptop
xx:xx:xx:xx:xx:xx 192.168.1.30 # LAN
xx:xx:xx:xx:xx:xx 192.168.1.31 # WLAN

Hint: You get the MAC-address using ipconfig -all on Windows or by using ifconfig on Linux/Unix.

/etc/hosts

maps IP address to full domain names, local domain names, and local hostnames. Example:

127.0.0.1   www.mydomain.com   localhost.lan   www.lan   localhost   www
192.168.1.4   ftp.mydomain.com   ftp.lan   ftp

Hint: you can also use a hosts file to block bad sites; see also custom hosts files

/etc/networks

configures the names and addresses of networks. this file is used by the route command. Example:

default   0.0.0.0       # default route    - mandatory
loopnet   127.0.0.0     # loopback network - mandatory
wlan      192.168.0.0   # local wireless network
lan       192.168.1.0   # local wired network

/etc/protocols

Usually you don't touch that.

/etc/config/network

See OpenWRT Kamikaze Manual for setting up basic network configuration

Example 0:
Bridging Ethernet and WLAN

config interface loopback
   option ifname lo
   option proto static
   option ipaddr 127.0.0.1

   option mode      ap          # access point mode
   option ssid      "My Fonera" # name of the router
   option hidden    1           # disables ssid broadcast
   option encyption psk2        # wpa2-psk
   option key       *********** # google 'wep key generator' to get a key

Installing Packages

After you have successfully configured a connection with the internet, you can load additional software packages using ipkg.

FIXME: If you compiled OpenWRT yourself, you can register your computer as the package repository

install packages

ipkg update
ipkg list | more
ipkg install <packagename>

uninstall packages

ipkg list_installed
ipkg remove <packagename>

CLONING

How to clone (or backup) a Fonera:

1. Get this expect script (written by Marius): https://whatever.metalab.at/user/kintel/fonera/clone.expect

2. Set up your fonera so you can ssh in without a password:

• Copy your computer's ~/.ssh/id_dsa.pub (or equivalent) to the Fonera
• On the Fonera:

  # cp id_dsa.pub /etc/dropbear/authorized_keys
  # chmod og-r /etc/dropbear/authorized_keys

3. Run the script on your computer

4. The backup is now made to the files clone.lzma and clone.squashfs. These can be used to reflash another fonera to become an identical copy.

Assumptions: The fonera lives at 192.168.1.1, the root prompt contains a "#", a normal openwrt is flashed on it.

NB! This has not been tested very well, so use with caution until it's been more quality assured. Bugreports are welcome :)
