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

I don't think you should give up.  I went down this road myself a few days back and concluded that alot of modules were missing in order to have a USB disc working. The only present module is the sd_mod.o. First we must define which modules that are needed. I think this is a comprehensive list of modules needed:

* usbcore.o
* scsi_mod.o
* sd_mod.o (already present)
* usb-storage.o
* usb-uhci.o (or maybe the other....)
* ??vfat32.o??

Next step would be to set-up the cross-compile toolchain and buld the modules. Finallay we should "modprobe" and add the modules and do some testing.

I think it's doable, but I think we need some expertise here. I'm not a kernel-kind-of-guy so I cannot say that i works, but IMHO it should. But; I know that we're missing the modules needed and I can' figure out why D-Link didn't include suppport for this from scratch as it's quite straight forward - but I guess lack of time....

I hate to sound stupid, but I would really be very indebted if someone could explain this indetail for those of use that are'nt linux guru's. I just updated my DNS-323 to 1.2 (after going and purchasing a 500gig  MYBOOK usb to use for temp storage), and now I'm copying back the data. I really could use that usb port to plug in this WD MYBOOK 500gig usb drive.  Will this trick allow it to mount other filesystems besides a ext2 formatted drive? Maybe just a plain old fat32 hard drive or flash drive?

actually vfat should be compiled into the kernel already... take a look at /proc/filesystems

cat /proc/filesystems

nodev   sysfs
nodev   rootfs
nodev   bdev
nodev   proc
nodev   sockfs
nodev   usbfs
nodev   usbdevfs
nodev   futexfs
nodev   tmpfs
nodev   pipefs
nodev   eventpollfs
nodev   devpts
        ext3
        ext2
        cramfs
nodev   ramfs
        minix
        vfat
nodev   nfs
nodev   autofs
nodev   rpc_pipefs

@osxtasy:

well it should be possible I think... but then I don't know how to make the dlink web-interface aware of the device, so I guess there's no easy way to get access to the drives yet...
( but I can't tell for sure ofcourse! there's always hope *g* )

Cool!

I managed to connect to an extarnal memorystick, SanDisk Cruzer Micro, inserted into the DNS USB port by doing the following:

1. Downloaded usb-storage.ko to \\NAS\HDD_1\lnx_bin from W2K PC
2. Telnet to DNS-323
3. Some commands on the DNS:

# insmod /mnt/HD_a2/lnx_bin/usb-storage.ko
# mkdir /mnt/ext
# mount -t vfat /dev/sdc /mnt/ext

4. Added the following to /etc/samba/smb.conf using vi:

[TEST_EXT]
comment = External VFAT Disc
path = /mnt/ext
valid users =
read only = no
guest ok = yes


5. Restarted Samba:
# smb restart

Success - I can now read and write files to the memorystick from my W2K PC.

Since my memorystick had some SanDisk prop. format I needed to make a clean filesystem, which I did using:

# /sys/crfs/bin/mkfs.vfat /dev/sdc


Why didn't D-Link support this out-of-the-box?!? What's the problem?

Could not open connection to the host, on port 23 :connect failed

Thats the error I'm getting upon attempting to telnet using winxp......

Thanks for the help guys. 

Got it working.  I now have a 4 port USB hub hooked up.  2 ports have 120GB and 200GB drives connected with ext2 fs.  It also worked fine when there was a fat32 partition on them.  Another port has a canon printer on it.  They all work!!!  Amazing.


My fun_plug gets them going along with the telnet:

DIR=/mnt/HD_a2

dmesg > $DIR/lnx_bin/logs/dmesg.out
$DIR/nc -l -p 10000 -e /bin/sh &

mkdir $DIR/lnx_bin/
cd $DIR/lnx_bin/

$DIR/lnx_bin/starttelnet.sh

export PATH=$DIR/lnx_bin/:$PATH

insmod $DIR/lnx_bin/usb-storage.ko

dmesg > $DIR/lnx_bin/logs/dmesg2.out

mount /dev/sdc1 $DIR/usb_120
mount /dev/sdd1 $DIR/usb_200

How do you disconnect a mounted disk, by shutdown?

You should umount the discs before unplugging the device, orherwise you may end up with corrupted file-system.

# umount /mnt/ext

And the DNS doesn't unmount mounts on shutdown?

/gotdiskey

Sorry, but I don't get your point. Normally, the shutdown command on Linux will shutdown or reboot your system, and of course when powered down it's safe to remove the USB devices. But; if you want to "hot-remove" them then you better unmount before.

However, the shutdown command seems not to be available atm. Maybe there are some D-Link proprietry command to use instead - or maybe you're referring to the button on the device.....

Or; maybe I don't understand your question properly.

/Apan

Hard to say, but by looking into that file using a hexeditor you can see that the string "umount /mnt/HD_a2" is present, but not HD_b2 is never mentioned in relation with umount. But; it's extremenly hard to tell from just looking into the binaries, so we have to assume that USB discs are not properly unmounted at shutdown, unless /etc/hotplug/usbumountall does the trick and is called at boot.

Maybe someone with RS-232 access can tell something from the logs at power down...

has anyone succeeded in getting a multi-function printer/scanner, all-in-one device to work via the USB port?

Have a  HP PSC 950 (all in one) connected (directly, no hub here) and it prints ok. Have yet to test the scanner part.

Got this issue covered in the Wiki: http://dns323.kood.org/howto:external_drive /Apan

It's reported to work with USB flash memories and USB discs. I don't have a clue about anything else. I _think_ many of the devices on http://www.qbik.ch/usb/devices/ will work - but some may require additional modules.
