First Step – Installing fun_plug

Installing fun_plug is simple. Download the fun_plug tar.gz file here and copy it to “volume_1” root (IE: dns-323/Volume_1/). Also download the “fun_plug” file (non tar-gz) and copy it to the same location.

Reboot (From admin click on “tools” and then “system”) the DNS-323 and  on reboot this file should expand and create a new directory: ffp. It also starts a telnet server (there is that out of the way).  In addition, the tarball contains these other packages:

• Lighttpd Web Server
• OpenSSH Secure Shell
• Mediatomb UPnP Media Server
• NTP Network Time Daemon
• UNFS3 User-Space NFS Server
• NFS-Utils NFS Server (requires kernel support)
• RSync File Transfer Utility

Second Step – Enable SSH

If all goes well you should be able to telnet into your d-link:

Last login: Sat Feb 28 19:32:18 on console
localhost:~ jordan$ telnet 192.168.0.198
Trying 192.168.0.198…
Connected to 192.168.0.198.
Escape character is ‘^]’.
/ #

Notice it asks for no username or password? No good. This is a big security hole and we need to disable this and enable SSH. Since it is part of the tarball package fun_plug we only need to enable it.

At the telnet prompt type:

1. pwconv
   
2. passwd - (this changes root password, enter twice)
3. usermod -s /ffp/bin/sh root – (this will change the default shell of the user. Current shell for root is ASH)
4. login - (test to make sure you can login)
5. store-passwd.sh
6. chmod 766 /ffp/start/sshd.sh – (this allows everyone to read/execute the SSH startup script. It will also allow it to startup on boot).
7. sh /ffp/start/sshd.sh start – (start the SSH service)

You should be able to SSH in. Try it now:

localhost:~ jordan$ ssh root@192.168.0.198
root@192.168.0.198’s password:
root@dlink-583ECB:~#

If you can, disable telnet by executing:

1. /ffp/start/telnetd.sh stop
   
2. chmod 644 /ffp/start/telnetd.sh

Installing Transmission

1. ssh as root
2. Type the command “cd /mnt/HD_a2” and hit <Enter>
   The prompt should change to “/mnt/HD_a2 #”
3. Type the command “wget http://kylek.is-a-geek.org:31337/files/curl-7.18.1.tgz” and hit <Enter>
4. Type the command “wget http://kylek.is-a-geek.org:31337/files/Transmission-2.04-1.tgz” and hit <Enter>
5. Type the command “funpkg -i curl-7.18.1.tgz” and hit <Enter>
6. Type the command “funpkg -i Transmission-2.04-1.tgz” and hit <Enter>
7. Type the command “chmod a+x /ffp/start/transmission.sh;sh /ffp/start/transmission.sh start”
   There would be a message like starting transmission
8. Type the command “sh /ffp/start/transmission.sh stop” and hit <Enter>
   There would be a message like stopping transmission
9. Do not close the command prompt.

Updating the whitelist

In this section we would be adding your local lan IP range (A.B.C.*) to the whitelist. Assuming your NAS’s IP is 192.168.1.101, A.B.C.* would simply mean 192.168.1.* where the last group of number becomes asterix (*).

1. Go back to the command prompt
2. Type the command “vi /mnt/HD_a2/.transmission-daemon/settings.json” and hit <Enter>
3. Edit the line with “rpc-whitelist”
4. Type the following “,A.B.C.*”
   The entire line would read something like
   “rpc-whitelist”: “127.0.0.1,192.168.1.*”,
   

Starting Transmission

1. Type the command “sh /ffp/start/transmission.sh start”
   There would be a message like starting transmission

Give it sometime for transmission to startup before proceeding to the next section.

Setting the download directory

1. Type the command “su nobody -c “mkdir -p /mnt/HD_a2/transmission-downloads”“
2. Type the command “transmission-remote 127.0.0.1 -w /mnt/HD_a2/transmission-downloads”
   There would be a message like success

It’s done! Direct your Internet browser to http://A.B.C.D:9091 for the transmission web user interface.

1) Modify system preferences by executing this line in a terminal.

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1


This will allow you to select the DNS as a backup device when you configure Time Machine.

2) You need to manually create a disk image that Time Machine can understand. The naming convention of this image is key. The name consists of the computers name and mac address of the local eno device without colons. (_.sparsebundle). Easiest way to find out the proper name is to attempt a backup after completing step 1 above. While this is attempting to run, use finder to browse the Volume (Volume_1 in my case) and write down the name of the file its trying to create. The filename will contain .tmp before the .sparebundle. Drop this from the filename and you have the complete name you need to use.

ie: gataca_0021413a0cce.tmp.sparsebundle -> gataca_0021413a0cce.sparsebundle

Open disk utility and create a new disk image on your local drive (you cannot create the image directly on the NFS drive) with the following options:

Format: Spare Bundle Disk Image
Partiions: No Partition Map
Encryption: None
Format: Mac OSX Extended Partition (Journaled)
Size – Maximum Size.. I choose Custom 250GB

After the image is created… manually copy it over to the root of your NFS volume.

3) Kick off the time machine backup and voila!

Now.. be prepared for the caveats of this solution mentioned here.
