Hello,
I got a problem. Today the new Wlan Router TL-WDR3600 arrived. i installed the OpenWrt: openwrt-ar71xx-generic-tl-wdr3600-v1-squashfs-factory.bin with LuCI and CUP for the printer. Then there wasn't enough space to install the printer driver: hplip
I heard about extroot and the possibility to change the installation destination for opkg...
-> http://wiki.openwrt.org/doc/techref/opkg
Detailed Instructions
First mount an external filesystem, see Mounting Filesystems for help with that. Then edit /etc/opkg.conf:
Add the line dest usb /opt to the bottom of the file
Execute the following command (assuming that /mnt/sda1 is the path to the mount point of your external filesystem):ln -s /mnt/sda1 /opt
Edit /etc/profile and add the new mount point to your paths variables:
export PATH=<current default path>:/opt/bin:/opt/sbin:/opt/usr/bin:/opt/usr/sbin
export LD_LIBRARY_PATH=<current default LD library path>:/opt/lib:/opt/usr/libFrom here, you should be able to install new packages to your new mount point as follows:
opkg update
opkg -dest usb install asterisk14 # or whatever else you want…If you install packages to external filesystems that have a startup script under /etc/init.d and (if enabled) under /etc/rc.d you need to set a sysmlink to /etc/init.d, e.g.:
ln -s /usb/etc/init.d/openvpn /etc/init.d/openvpn
Libraries installed along with those packages are also installed to the external filesystem. This causes the programm not to start during bootup. You need to manually set the LD_LIBRARY_PATH in each 'external' startup script:
export LD_LIBRARY_PATH=/lib:/usr/lib:/tmp/lib:/tmp/usr/lib:/usb/lib:/usb/usr/lib
I made a mistake in /etc/profile maybe the LD_LIBRARY_PATH was wrong. I did not correct it. Instead of it, I started to reload the openWrt firmware to get a new fresh system without all the unnecessary installed packages. 
After the reboot the webinterface was not reachabel as supposed. 
But i can directly connect with SSH and my old password and most commands do not work now...

Is there a way to reset this. Most of the commands don't work.
I am looking forward to hearing from you. Thanks!
