DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hi all,

I've been toying around with a script to automate the creation (simulation?) of runlevels for
the dns-323 running funplug.  I thought I'd throw it up here incase anyone is working on something
similar or is curious.

It will overwrite the funplug rc system, so it's may be a good idea to do a cp -rp on your ffp folder
to back it up! (I have 3 revision B's, and it works great for me on them… I've written this around
funplug 0.7, I have no idea if it will even work with 0.5)

It creates some scripts in /ffp/etc/rc.d to launch each runlevel, and keeps symlinks in /etc/rc0.d - rc6.d
similar to how other linux distros handle runlevels.  By default it has the following setup:

   0  - Halt             - Shut down Funplug for poweroff
   1  - Single User Mode - utelnet shell + the Dlink Firmware load is halted
   2  - Debug Mode       - utelnet shell + the Dlink Firmware loads normally
   3  - Dlink Mode       - Dlink Firmware loads normally
   4  - Not used but available for customization
   5  - Full Funplug     - Dlink Firmware loads normally + Funplug Scripts
   6  - Reboot           - Shut down Funplug for reboot

It also modifies the fun_plug script that gets called from /mnt/HD_a2 to execute the appropriate scripts
from /ffp/etc/rc.d

A 'chkconfig' utility is installed that allows you to manage runlevels in a similar fashion to rhel
and centos.  A 'runlevel' utility is also installed to allow easy switching between runlevels.
This in itself is what made it worth the effort for me. (Try 'chkconfig -h' or 'runlevel -h')
A .inittab file located on /mnt/HD_a2 keeps track of the runlevel, so you can edit this via SMB
as another method of switching runlevels on each boot.

*You'll need to install the utelnetd package to get the default runlevels 1 and 2 to work.  This will
make a tiny telnet daemon available that can be run from the ramdisk to avoid disk dependencies.
(The package was built from files taken from http://dns323.kood.org/howto:telnet - not my own work)

*I've also put together a modded version of that amazing chkbutton2 script to use rc0 and rc6, to seamlessly
integrate with this runlevel management method.  It's available if anyone wants to try it out.
