La Fonera's IPKG Bug

Posted by coldtobi | 6 Jul, 2007, 23:12

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:

 wget http://blog.coldtobi.de/gallery/1/ipkg.txt -O /tmp/ipgk && md5sum /tmp/ipkg

Only proceed, if the outputted md5 is "3a3db0906383bd16bbcebd7dfd8a663a  /tmp/ipgk". If not, at least check the downloaded file if it looks like a shell script.

After you verified it, you can

mv /tmp/ipkg /usr/bin/ipgk

But stay away from ipgk update! As the kernel image is not writeable, and "newer" kernel modules would be installed, these won't match leading to unbootable box.

    I stucked my fonera!

    This is output from console:

    root@OpenWrt:~# wget http://blog.coldtobi.de/gallery/1/ipkg.txt -o /usr/bin/ipgk; chmod 0750 /usr/bin/ipkg
    wget: illegal option -- o
    BusyBox v1.1.3 (2006.09.11-19:54+0000) multi-call binary

    Usage: wget [-c|--continue] [-q|--quiet] [-O|--output-document file]
    [--header 'header: value'] [-Y|--proxy on/off] [-P DIR] url

    wget retrieves files via HTTP or FTP

    Options:
    -c continue retrieval of aborted transfers
    -q quiet mode - do not print
    -P Set directory prefix to DIR
    -O save to filename ('-' for stdout)
    -Y use proxy ('on' or 'off')

    The small "-o" was wrong. Needed be "-O"
    However this won't break your Fonera: The command simply fails -- doing nothing -- not touching any file.

    However, even if it'd screwed ipkg: It is not required for a successful boot.

    I suppose you should give it a second try to let it boot or/and retry factory reset (follow the instructions on this blog.)

    OK. Now I know this.. but my fonera hangs after this operation, and newer booted again :/

    I'm going to flash it by RS232, but I'm waiting for all elements to build cable to connection :P

    Internet LED is flashing, but WLAN don't.
