Rebuild MiniPwner

Hi,

I just wanted to use my MiniPwner again after some months where it was just placed on my desk and unfortunately I forget the password and I also didn't wrote it in my KeePass File.

So I had to reinstall it. Luckily there is a rebuilding instruction of the MiniPwner in case there went something wrong with your MiniPwner (or you just forget about the password ;-) ).

In the rebuilding instructions it is mentioned to get the "squash-sysupgrade.bin". I couldn't get it on this URL as the folder is empty. So I used the latest firmware "openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory" for the TP-Link router from this directory on openwrt. The MD5Sum I got was:

root@Pulse:/tmp# md5sum owrt.bin
5d7bac7b467c42e215c60fcd0a00cc01

The image is available again.

On your Client where you've placed your openwrt image, you just start your netcat server.

# nc -l -p 3333 < openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

On your TP-Link now just get the image via netcat:

# nc 192.168.1.2 3333 > /tmp/owrt.bin

The file should be on your TP-Link within a few seconds so you can abort the netcat session on it. After that just install the firmware:

# mtd -r write 703.bin firmware

After the installation of the firmware is done, which shouldn't take longer than one or two minutes, you need to configure your interface of the client that is connected to TP-Link to DHCP. The IP of TP-Link should be 192.168.1.1. You can now telnet to this IP:

$ telnet 192.168.1.1
Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.
 === IMPORTANT ============================
  Use 'passwd' to set your login password
  this will disable telnet and enable SSH

You should now change your root password so that you can login via ssh in the future. Then you can ssh to your TP-Link and can continue the installation instructions on minipwner.org at step 12.

You can also navigate now to the Webgui under http://192.168.1.1/cgi-bin/luci.

IMPORTANT:

Right now it is not possible to execute "opkg update" as all the files in http://downloads.openwrt.org/snapshots/trunk/ are missing. There are several tickets about this issue, here and here.

But they are both almost 2 weeks old and it's not clear when the files are coming back. So here is what I did (thanks to flyingstar16, who posted this hint in one of the tickets):

1. Comment out the lines in /etc/opkg/xwrt.conf

root@Pulse:/etc# vim opkg/xwrt.conf
#src/gz X-Wrt http://downloads.x-wrt.org/xwrt/snapshots/trunk/ar71xx/packages

2. Comment out the line to http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages as it is not working and add the line "src/gz attitude_adjustment http://downloads.openwrt.org/attitude_adjustment/12.09-beta/ar71xx/generic/packages"

root@Pulse:/etc# vim opkg.conf

src/gz attitude_adjustment http://downloads.openwrt.org/attitude_adjustment/12.09-beta/ar71xx/generic/packages

#src/gz snapshots http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay

3. Now you can execute opkg update.


Some other hints:

When copying all the files in Step 19 in /etc/ to make a backup of them, I hadn't a firewall config and fstab. See my output:

root@OpenWrt:/usr/share# cp -f /etc/config/network /etc/config/network.orig
root@OpenWrt:/usr/share# cp -f /etc/config/wireless /etc/config/wireless.orig
root@OpenWrt:/usr/share# cp -f /etc/config/firewall /etc/config/firewall.orig
root@OpenWrt:/usr/share# cp -f /etc/profile /etc/profile.orig
root@OpenWrt:/usr/share# cp -f /etc/config/fstab /etc/config/fstab.orig
cp: can't stat '/etc/config/fstab': No such file or directory
root@OpenWrt:/usr/share# cp -f /etc/opkg.conf /etc/opkg.conf.orig
root@OpenWrt:/usr/share# cp -f /etc/config/system /etc/config/system.orig
root@OpenWrt:/usr/share# cp -f /etc/config/dhcp /etc/config/dhcp.orig
root@OpenWrt:/usr/share# cp -f ./network.1 /etc/config/network
cp: can't stat './network.1': No such file or directory
root@OpenWrt:/usr/share# cp -f ./wireless.1 /etc/config/wireless
cp: can't stat './wireless.1': No such file or directory
root@OpenWrt:/usr/share# cp -f firewall.1 /etc/config/firewall
cp: can't stat 'firewall.1': No such file or directory

But everything worked fine. I also skipped step 20 and 21 as the right MAC-Address for WiFi was already in the config. 

Here is a good explanation how to configure WiFi in OpenWRT.

Have fun.
