Setting up ffp

There is a complete Tutorial on the Installation of ffp available on NAS-Tweaks: Installation of fun_plug 0.5. If you want to do everything yourself instead, just follow the instructions below.

To get the fonz fun_plug running some small changes to the available ffp fun_plug file are needed.

Search and replace all entries of /mnt/HD_a2/ with /mnt/HD/HD_a2/.

Then follow the normal instructions of how to install ffp.

shadowandy has provided modified ffp package for DNS-320 here

Another article in German on installing fun_plug 0.5 can be found here

Once installed and running you might want to set-up ssh and change the root password. (for example this)

But to need to change store-passwd.sh also because that is functioning differently on our device. It can be found at /ffp/sbin/store-passwd.sh

And make it look like this:

#!/bin/sh

echo "Copying files to /usr/local/config/..."
cp -f /etc/passwd /usr/local/config/.
cp -f /etc/group /usr/local/config/.
cp -f /etc/shadow /usr/local/config/.
cp -f /etc/samba/smbpasswd /usr/local/config/.

Installation and Configuration of Transmission with addons

Contributed by Zane Chua on 10th June 2011.

First of all, you need Funplug 0.5 above. SSH into the NAS by using PuTTY. Installation of Transmission:

wget http://kylek.is-a-geek.org:31337/files/curl-7.18.1.tgz
wget http://kylek.is-a-geek.org:31337/files/Transmission-2.42-1.tgz
funpkg -i curl-7.18.1.tgz
funpkg -i Transmission-2.42-1.tgz


Once installed, you need to edit the transmission.sh in /ffp/start SSH into the NAS by using PuTTY again. Type these commands:

wget http://ffp.wolf-u.li/additional/app-editors/nano-2.0.9-2.tgz
funpkg -i nano-2.0.9-2.tgz
cd /ffp/start/
nano transmission.sh

Edit the line from

TRANSMISSION_HOME=/mnt/HD_a2/.transmission-daemon 

to

TRANSMISSION_HOME=/mnt/HD/HD_a2/.transmission-daemon

Press Ctrl + O and Ctrl + X
After that, i believe that you would want to access the Transmission Web Interface.
SSH into the NAS by using PuTTY again.

/ffp/start/transmission.sh stop
su nobody -c "transmission-daemon -f -g /mnt/HD/HD_a2/.transmission-daemon -w /mnt/HD/HD_a2/Downloads -a 127.0.0.1,192.168.1.*"


I downloaded Transmission Torrent Client Utilities v0.2 from http://dns323.thecorewithin.net/
Run this code via SSH again

wget http://dns323.thecorewithin.net/trans_utils-0.2.tgz
mv trans_utils-0.2.tgz /mnt/HD/HD_a2/trans_utils-0.2.tgz
cd /mnt/HD/HD_a2/
tar xvzf trans_utils-0.2.tgz
cd trans_utils-0.2
nano install.sh

Change the line from

BASE_SHARE=/mnt/HD_a2 

to

BASE_SHARE=/mnt/HD/HD_a2

Press Ctrl + O and Ctrl + X

Continue with the code:

cd scripts
nano torrent_utils.sh

Change the line from

BASE_SHARE=/mnt/HD_a2

to

BASE_SHARE=/mnt/HD/HD_a2

and the line from

TRANSMISSION_HOME=/mnt/HD_a2/.transmission-daemon

to

TRANSMISSION_HOME=/mnt/HD/HD_a2/.transmission-daemon

and the line from

WATCH_DIR=$BASE_SHARE/watch

to

WATCH_DIR=$BASE_SHARE/Downloads/watch 

and the line from

COMPLETE_DIR=$BASE_SHARE/complete

to

COMPLETE_DIR=$BASE_SHARE/Downloads

Search for the line

mv "$COMPLETE_DIR/${SEEDING_FILENAME}.moving" "$COMPLETE_DIR/${SEEDING_FILENAME}"

Add this line below it

chown -R *USERNAME* "$COMPLETE_DIR/${SEEDING_FILENAME}"

Replace *USERNAME* with a User you created in the Web Configuration so anyone can edit the files
Press Ctrl + O and Ctrl + X

Continue with the code:

cd ..
cd start
nano trans_utils.sh


Change the line from

TRAN_UTILS=/mnt/HD_a2/.transmission-daemon/scripts

to

TRAN_UTILS=/mnt/HD/HD_a2/.transmission-daemon/scripts


Continue with the code:

cd ..
./install.sh

It shouldn't have any issues running but it should make a watch and complete folder in /mnt/HD/HD_a2 which is not even used so we shall just remove them and create them in the proper directories
Continue with the code:

cd ..
rm -rf watch
rm -rf complete
cd Downloads
mkdir watch
cd ..
/ffp/start/transmission.sh stop   (wait a while after this)
chown -R nobody /mnt/HD/HD_a2/.transmission-daemon
chown -R nobody /mnt/HD/HD_a2/Downloads


Extras
If you're a paranoid freak like me and you want to be able to remote access your DNS-320 not from your home and want to use a different port.
You have to change the line in torrent_utils.sh from

TRANS_REMOTE=$BASE_SYS/bin/transmission-remote 

to

TRANS_REMOTE="$BASE_SYS/bin/transmission-remote Port" 


and then if you're intending to use authentication by username and password you have to add the username and password in the respective fields in the Settings.json File located in /mnt/HD/HD_a2/.transmission-daemon.
Then you have to change the line in torrent_utils.sh from

TRANS_REMOTE=$BASE_SYS/bin/transmission-remote 

to

TRANS_REMOTE="$BASE_SYS/bin/transmission-remote port --auth username:password"

That should work. Theoretically. If something is wrong with my commands, can someone please edit.
Configuration of Automatic.
I just recently decided to test out Automatic again, i had issues the last time but it seems everything works perfectly now so i'm including this here.
SSH into your NAS via PuTTY and make sure you're in /mnt/HD/HD_a2

wget http://kylek.is-a-geek.org:31337/files/Automatic-0.7.1-1.tgz
wget http://www.inreto.de/dns323/fun-plug/0.5/packages/libxml2-2.6.31-2.tgz
wget http://www.inreto.de/dns323/fun-plug/0.5/packages/pcre-7.7-1.tgz
funpkg -i libxml2-2.6.31-2.tgz
funpkg -i pcre-7.7-1.tgz
funpkg -i Automatic-0.7.1-1.tgz


You then need to edit the automatic.sh located in /ffp/start.

cd /ffp/start/
nano automatic.sh

Edit the line from

automatic_flags="-c /ffp/etc/automatic.conf -l /mnt/HD_a2/.transmission-daemon/automatic.log"

to

automatic_flags="-c /ffp/etc/automatic.conf -l /mnt/HD/HD_a2/.transmission-daemon/automatic.log -v 2"

Press Ctrl + O and Ctrl + X

Now you need to create a automatic configuration file. We'll use the sample file.

cd /ffp/etc/
nano automatic.conf-sample

Remove the # from rpc-host and rpc-port.
If you need #rpc-auth means you've configured a username and password for Transmission.
Change the line from

torrent-folder = "/tmp"

to

torrent-folder = "/mnt/HD/HD_a2/.transmission-daemon/autotorrents"

and the line from

statefile = "~/.config/automatic.state"

to

statefile = "/mnt/HD/HD_a2/.transmission-daemon/automatic.state"

Edit in your RSS Feeds and filters
Press Ctrl + O when you're done and save it as automatic.conf then Press Ctrl + X
Now we need to go create the folders and state file for automatic. Fire up PuTTY again and do these commands:

cd /mnt/HD/HD_a2/.transmission-daemon
mkdir autotorrents
touch automatic.state
chmod 777 automatic.state


Now you can start automatic.sh by typing

/ffp/start/automatic.sh start

If you want to stop automatic

/ffp/start/automatic.sh stop


Just some tips for the Filters. My RSS Feeds are basically sorted out so I used this section for filters

filter = {  pattern => "(?!.*.)" 
         }

It basically means that it applies to all RSS Feeds.
All my commands should be correct, someone edit em if they're wrong. Have fun!

Changing the port of Web Configuration Utility


Contributed by Anand Kothapeta on 5/20/2011.

I was running two NAS servers (one D-Link DNS-320 and my old PC with FreeNAS) and a web server on a different PC. These are all behind my router. My router and FreeNAS allows me to change the default port for the web configuration utilities. So, I can change them from port 80 and port forward them, and can access the web configuration utilities from internet. However I always have an issue with DNS-320, since it doesn't allow me to change the port and it conflicts with web server. There are some articles on how to change it by running lighttpd. However, I found out that DNS-320 also uses the lighttpd to run the webconfig utility. Also those articles change the port to 81 (not much flexibility). I finally figured out a way to change the port to whatever I wish it to be. Here are the steps. You need to first install the ffp using above articles and links.

1) telnet/ssh login to the DNS-320 box. (see ffp tutorials) and run the following command

cp /etc/lighttpd/lighttpd.conf /ffp/lighttpd_portmod.conf


2) Now edit the /ffp/lighttpd_portmod.conf file and change the following line to lets say 8888 and save the file.

server.port = 8888


3) edit the fun_plug script and add the following lines between fun_plug.local and FFP_RC if conditions.

# run fun_plug.local, if present
if [ -x /ffp/etc/fun_plug.local ]; then
    echo "* Running /ffp/etc/fun_plug.local ..."
    /ffp/etc/fun_plug.local
fi

#*** start Mods for different http port for webadmin tool
echo "killing  lighttpd-angel"
kill -9 `pidof lighttpd-angel`
echo "killing  lighttpd"
kill -9 `pidof lighttpd`

echo "Restart  lighttpd-angel with different port"
/usr/sbin/lighttpd-angel -D -m /usr/local/lib -f /ffp/lighttpd_portmod.conf &
#*** end Mods different http port

# run commands
if [ -x $FFP_RC ]; then
    echo "* Running $FFP_RC ..."
    $FFP_RC
    echo "*  OK"
else
    echo "$FFP_RC: Not found or not executable"
fi


4) Now reboot it.

5) Look at ffp.log to make sure you see the following lines.

killing  lighttpd-angel
killing  lighttpd
Restart  lighttpd-angel with different port


6) Now open the browser and try http://<ipaddress>:8888/ should take you to the web config tool.

7) Now you can port forward 8888 in your router, and port forward 80 to web server.


Setting up Debian in chrooted enviroment

D-Link has recently put a prebuilt Debian Squeeze package on their ftp site. The package size is approximately 150 MB. Read the instruction inside. You may have to modify –bind (dash-dash-bind) to –rbind (dash-dash-rbind) for the /proc (and possibly /dev) mounts in fun_plug.debian to get some usb devices (e.g. the DS9490R USB-1wire adapter) to work properly in squeeze.

the prebuilt Debian Squeeze package is NO LONGER available (anywhere?)as of july 2014, with no alternative build options ,compiling new apps are left to only the semi pro devs that can create their own dev systems.

Source code for firmware

Dlink have release source code for firmware 1.0 on their ftp site. The source code size is approximate 25 MB

U-BOOT Configuration

You can access the boot console (for trying to run your own kernel) via a netconsole. To interrupt the U-Boot startup, press SPACE and 1 before the one-second timeout. You should get a Marvell_DNS320» prompt immediately. If the kernel starts to boot, you missed the timeout window. Starting ahead of the timeout and pressing SPACE-1-SPACE-1, etc. will increase you chances of hitting the window.

The full U-Boot environment (MAC addresses hidden) is:

Building a Custom Firmware ("ROM")

D-Link provides a complete build environment on its ftp server that lets you create your own firmware images easily. Untar it and run

 source build_fw 

this will result in a file “DNS320-firmware” in the merge folder, which can be flashed to the unit via the webinterface (firmware update). Right now the build_fw script does not do a full rebuild of the complete firmware, it rather puts together precompiled binaries that come with the built environment. Here is an attempt at rebuilding the build script. This blog post describes how to assemble a firmware image for the DNS-323 and will probably helpful for the DNS-320 as well.

Use this custom build_fw to make a custom settings for the kernel

This Program works simlure as Dlink 320 merge does. It have been create by Magnus Olsen and release under GPL 2.0 The header for firmware are lite diffent againts DNS-323 to use it as merge u need compile it gcc dns320flash.c -o dns320flash copy where merge is and type dns320flash -mf myDNS320firmware now u will have a firmware call myDNS320firmware

Other info

The following thread handles some DNS-320 initial conversation, request there if you want some specific info here, or add yourself.

Fan Speed settings

With ffp is enabled, login to the box via telnet and run FT_testing

ex:

/ # FT_testing -H
Fan and Temperature Testing Tools
Usage
FT_testing      -H      ...Help message
FT_testing      -T      ...Get Temperature
FT_testing      -F      ...Set Fan in Full Speed
FT_testing      -L      ...Set Fan in Low Speed
FT_testing      -S      ...Set Fan Stop
FT_testing      -A      ...Print Receive UART Packet.
FT_testing      -G      ...Get Fan Status.
FT_testing      -P      ...Power off system.
FT_testing      -R      ...Reboot system.

if you need the fan is always off, type:

ps uax |grep fan_control

and kill this process

or

killall fan_control

, and run

FT_testing -S

/code

SSH Access

This is just a quick n' dirty way to get root access to the device. This configuration is not recommended as permanent.

  1. Create fun_plug
  2. Create sshd_config
  3. reboot dns-320

File 1 fun_plug *

#!/bin/sh
# credit to
# http://webapps.itcs.umich.edu/radmind/index.php/Generate_ssh_host_keys
# for the scripted ssh-keygen

ssh-keygen -q -t dsa -f /mnt/HD/HD_a2/ssh_host_dsa_key -N ""\
    -C "" < /dev/null > /dev/null 2> /dev/null

/usr/sbin/sshd -f /mnt/HD/HD_a2/sshd_config

File 2 sshd_config *

Port 22
Protocol 2
HostKey /mnt/HD/HD_a2/ssh_host_dsa_key
PermitEmptyPasswords yes
PasswordAuthentication yes
ChallengeResponseAuthentication no
TCPKeepAlive yes

* Create the files with a Linux compatible text editor (Like Notepad++)

Connect: ssh root@dns_ip
