Inside the Fonera · Friday October 13, 2006 by jauzsi
$5 for a wireless AP is no big money, however in this case you get a completely closed box with no telnet or ssh. No known bugs in web interface, firmware upgrades are digitally signed. So what do we do?
Of course we open it up! (2 screws at the front under the rubber pads)
Inside you’ll find pinouts for a serial connector
Connect a ttl level shifter (aka max232, etc).
Serial pinouts for the Fonera:
- VCC (3.3V) – red
- GND – blue
- RX – white
- TX – orange
For the colorblinds:
. . . . r
. w o . b
Serial console settings: 9600-8-N-1 (no flow control)
Something to chew on:
bootloader + dmesg
Enable SSH:
- # mv /etc/init.d/dropbear /etc/init.d/S50dropbear
- # vi /etc/firewall.user
- press i
Uncomment the two lines at the SSH section, so it will look like this:
iptables -t nat -A prerouting_rule -i $WAN -p tcp—dport 22 -j ACCEPT
iptables -A input_rule -i $WAN -p tcp—dport 22 -j ACCEPT
- press esc
- type :wq
- press enter
Now you can reboot or type these:
- # /etc/init.d/S50dropbear
- # /etc/firewall.user
Happy hacking!
