Some days ago, I patched the La Fonera to support RedBoot over Ethernet. As this is a very good opportunity trying out OpenWRT, I am gonna install OpenWRT on this piece.
Booting La Fonera -- Redboot Bootloader
RedBoot is the bootloader used in the La Fonera. As this bootloader can not only operate over RS232, it also can be configured to offer a simple -- but powerful -- dedicated shell over telnet / Ethernet. This is also true for the La Fonera, but has only one problem: It has no IP configured, therefore you cannot use it. We'll gonna change that now!
Update: Now, 2014, the original locations of the files are gone. Please see the bottom of the post for an solution.
La Fonera+ is designed to be more easier to install and harder to hack: All the known bugs have been eliminated, the on-board-serial does not reveal a console anymore, the communication with fon is also encrypted (ASFAIK) using DNS and maybe more.
But they forget, that if you lock someone out -- especially in a community --, it but there are always smart people just encouraged by this. Here's the result:
An Article in the category: Do Not Brick Your Fonera Router. If you break it, you'll have to keep the pieces.
The ipkg binary in the fonera is broken. It is not really the ipkg binary, which is broken. So it can happen, that -- especially a ipkg remove -- can delete some essential directories. /lib/ for example, effectivly break the router.
But there is an script available, which replaces ipkg to get it safe. Just execute the following (on Fonera)
wget http://blog.coldtobi.de/gallery/1/ipkg.txt -O /usr/bin/ipgk; chmod 0750 /usr/bin/ipkg
[Update:] Safer is:
Day after day, the protest against the
security problems actions of fon get stronger. Now, it seems that some people are showing their protest against the
promotion, the fon community is on strike.
Due the recent security problems, here's a short how-to disable the public FON Access Point without interferring with the private network.
Note: A this is probably considered as breach of the agreement you made with FON, this is on your own risk. You probably want to suspend roaming as well while your fonera is crippled.
Just unplugging the antenna is not a good solution, as it might destroy some electronics in the La Fonera.
Disclaimer: DO NOT BRICK YOUR FONERA. BY MODIFING THE FONERA THORUGH SSH, IT IS POSSIBLE TO BRICK IT, ESPECIALLY IF YOU DON'T KNOW WHAT YOU ARE DOING. ALSO THIS HOWTO CAN CONTAIN ERRORS. IF IT BREAKS IT, IT IS YOUR PROBLEM, NOT MINE. YOU HAVE BEEN WARNED! (However, a factory reset should always be possible, at least you did not screw it up completly.)
FON (www.fon.com) recenetly changed it mind. Up to yesterday, you had to be linus or pay for free internet access abroad. "Bills", the members decided to make money out of the sharing, would also have to pay for access out of his own hotspot.
But these days are gone. Now, even Bills can get internet for free. They also encourage Linuses to change their profiles to Bills.
Well, there is at least one question which arose instantly: Why is FON doing this?
Read on for some speculations and why to be cautionous.
