I added the follwing line to my fun_plug script:
kill -9 `pidof upnp`This kills the standard shaky upnp server that is run on the CH3WNAS and constantly spawns errors in dmesg.
Next, I managed to run Gentoo under chroot on CH3WNAS. For this, I had to follow the steps on an excellent wiki: http://dsmg600.info/howto:chroot_gentoo. After ftping (i use gFtp) the files to the device and telneting to it, it's simply a matter of copy pasting the commands one-by-one. The 2 bzcat commands take some time to complete.
As I understand, the main purpose of running Gentoo under chroot is to have a recent Linux that can start modern binaries like dropbear (ssh), FireFly(iTunes specific daap), MediaTomb (uPnP), MLDonkey (torrent client), lighthttp (http server),...
For now, I simply have tried the bash:
/mnt/HD_a2/chroot /mnt/HD_a2/gentoo /bin/bash
This is currently my fun_plug:
#!/bin/shI tried out dropbear (ssh), but I couldn't figure out what user/password to use when ssh-ing to the CH3WNAS. I did some unsuccessful experiments with copy/pasting the /etc/shadow and /etc/passwd under /mnt/HD_a2/gentoo. --> I'll look at it later, but now I have gentoo as a basis to try out other stuff.
dmesg > /mnt/HD_a2/dmesg.out
if [ ! -e /mnt/HD_a2/ash ]
ln -s /mnt/HD_a2/busybox /mnt/HD_a2/ash
if [ ! `grep root /etc/shadow` ]
echo kontroll.`grep admin /etc/shadow` >> /etc/shadow
/mnt/HD_a2/sed -i -e 's/kontroll.admin/root/' /etc/shadow
/mnt/HD_a2/sed -i -e 's/root:.*/root:x:0:0:Linux User,,,:\/:\/mnt\/HD_a2\/ash/' /etc/passwd
cd /dev && /mnt/HD_a2/busybox makedevs ptyp c 2 0 0 9
cd /dev && /mnt/HD_a2/busybox makedevs ttyp c 3 0 0 9
/mnt/HD_a2/busybox telnetd &
#kill legacy upnp
kill -9 `pidof upnp`
#prepare gentoo stuff
mount -o bind /dev /mnt/HD_a2/gentoo/dev
mount -t proc none /mnt/HD_a2/gentoo/proc
cp /etc/resolv.conf /mnt/HD_a2/gentoo/etc/
#dropbear (ssh) stuff (not operational yet)
#ln -s /dev/urandom /dev/random
#/mnt/HD_a2/chroot /mnt/HD_a2/gentoo /usr/sbin/dropbear
dmesg > /mnt/HD_a2/dmesg.out2
Those hacks make the CH3WNAS very appealing for the more advanced user.
An idea for my future experiments: tweak the power button
