The problems I described last time, are gone now 🙂 The paramiko mailinglist is, besides the pretty good documentation, a very good information ressource.
So I built a Fon client in Python which allows you to login to the Fon server and make your Fonera officially online.
So in order to get your copy of PyFON, do a
hg clone http://hg.cryptobitch.de/pyfon
To use it, simply give the MAC address of your Foneras wireless interface as an argument and run it or do it in a more sophisticated way:
muelli@xbox:~/hg/pyfon$ python ./src/pyfonclient.py --loglevel info --firmware 0.7.2 --revision 3 --mode cron --ethernetmac 00:18:84:fo:ob:ar 00:18:84:fo:ob:ar
INFO:root:Connecting to host: download.fon.com:1937 as user: openwrt
INFO:paramiko.transport:Connected (version 2.0, client OpenSSH_4.3p2)
INFO:paramiko.transport:Authentication (publickey) successful!
INFO:paramiko.transport:Secsh channel 1 opened.
INFO:root:Found _auth_string: mode='cron' wlmac='00:18:84:ff:ee:dd' mac='00:18:84:fo:ob:ar' fonrev='3' firmware='0.7.2' chillver='1.0-1' thclver='1.0' device='fonera'
INFO:root:Finally closing everything
If you increase the loglevel to, say, debug, then you’ll get the script which Fon send you and supposes you to execute. If you change your password via the Fon webinterface, you’ll see your new password in that script.
So if you want to disturb the Fon network, you can iterate over all Fon MACs and receive the possible made configuration changes. By that, you’ll get the new passwords as well, of course…
Another funny thing is that the Fon server sends you their banner, if you explicitely request a shell:
In : import pyfonclient
In : c = pyfonclient.Client()
In : c.connect()
In : channel = c.client.invoke_shell()
In : channel.recv_ready()
In : buf=""
In : while channel.recv_ready(): buf += channel.recv(1)
In : print buf
