[jayshomebrew]

I am new to the nas firmware mods, so it took me a couple of days to figure this out. With the help of nas-central how-to, I got this info so far:

It looks like this:


I would like to add rsync if possible. Could you point me in the right direction?

Once I get a little further, I can post how I changed my root disk.

[Mijzelf]

A Gemini! Is that a new NAS?

Anyway, I think the easiest way to get rsync running is to install FFP. Download fun_plug.tgz. Create a directory ffp on your harddisk, and extract the tarball there. (Preferably using a shell).

Now create a symlink /ffp:

Code: Select all

ln -s /mnt/ide1/path/to/ffp /ffp

enable the rsync daemon

Code: Select all

chmod a+x /ffp/start/rsyncd.sh

and start FFP:

Code: Select all

/ffp/etc/rc start

You might want to exchange the root shell:

Code: Select all

sed -i " \|^root:|s|:\bin\sh|:\ffp\bin\sh|g" /etc/passwd

Now if you login you automatically get the FFP shell (with FFP path).

If you want this permanent, you'll need to find a way to run a user script on boot, which does:

Code: Select all

ln -s /volume1/path/to/ffp /ffp
/ffp/etc/rc start

It is possible that if you create a script /mnt/ide1/fun_plug, that it will be executed.

This NAS came on sale to microcenter.com a few weeks ago for $50, so I picked one up. I think they're just trying to get rid of them, since they're old hardware, but nice for someone like me to tinker with.

There are several rc.start and rc.sh scripts that are all accessible so I can permanently add it to check for ffp on the sata disk and/or the usb stick.

Have you tried if it won't revert?
According to your mounts there is some 30MB ramdisk, which might contain your whole rootfs. In that case you can change what you want, after a reboot it's gone.

[jayshomebrew]

I just followed nas-central's instructions on how to mount the root disk, modified it, then re-uploaded the firmware. If I do it this way, it keeps my changes.

ffp works great:

so I'm just getting around to modifying funplug.sh (http://ffp.inreto.de/ffp/0.7/oabi/fun_plug) script specifically for the CN-330.

Is $SETUP variable an error?

Code: Select all

if [ -x $FFP_SETUP_SCRIPT ]; then
    echo "* Running $SETUP ..."
    . $FFP_SETUP_SCRIPT
fi

Also, I'm not sure why we want to remove the tarball.. or maybe I'm reading this wrong.

Code: Select all

# install tarball
...
    rm $FFP_TARBALL
fi

[Mijzelf]

Is $SETUP variable an error?

Yes, I think so.

Also, I'm not sure why we want to remove the tarball.. or maybe I'm reading this wrong.

The existence of the tarball is the trigger to extract it at boot. So after extracting the tarball has either to be renamed or deleted.

The installation of FFP on the DNS323 involves writing the script fun_plug to the root of the harddisk, and the tarball. On boot the script will be executed, and the first time it extracts the tarball, and starts FFP. On subsequent boots only FFP has to be started.

Hi all, I stumbled on this thread when I was researching how to make fuse/libntfs work properly on this NAS. I also picked up the CN-330 at the microcenter sale to use as a media store.

Could you refer me to the documentation you found on modifying/reflashing the root disk? I have a series of commands that make the NAS perfectly functional for me but I have to run them manually every time I boot the device.

BTW, the reason I'm using NTFS is due to a limitation of Samsung BD-C5500 bluray player. It will play media on an external drive formatted ONLY as FAT32 or NTFS, so ext3 is out. FAT32 won't work due to the 4gig limit.

Sorry for being newbish.

FYI - I found that even though it is not listed on the webpage, coolmax is hosting their firmware for this device which is flashable via the web interface. It could make modding the flash easier.

http://www.coolmaxusa.com/download/firm ... 30NTFS.ZIP

[Mijzelf]

Wow. That one is easy to hack! No checksums, no nothing. The zipfile contains a gzipped ext2 image, which is the rootfs. Just mount it, change whatever you want, repack it, and upload to the NAS.

I think.

When you only need some script executed on boot, I think there is a symlink /usr/hddapp, which points to /mnt/<something>/hddapp, where /mnt/<something> is the mountpoint of a harddisk.
The executable scripts *.sh in /usr/hddapp/etc/init.d/ are executed on boot by /etc/rc.

[jayshomebrew]

This one works too, not sure what the diff is.
http://www.coolmaxusa.com/download/Firmware/CN-330.ZIP

I noticed that you can enable telnet just from here:
http://CN330-IP/cgi/telnet/telnet.cgi


root passwd is admin


I just ended up adding
S99funplug.sh to the /etc/rc.d of the root disk, following the directions: nas-central

then I put this on my usb stick:
funplug_cn330.sh

then you should get this under your admin log: which loads ffp


Also if you enable sshd funplug ver 0.7 will hang during boot. Edit the ffp script /ffp/start/sshd.sh (someone else on this forum gets credit for this help)

Thanks to share this informational link but your link doesn't work so please rectify it.
