SABnzbd with Bonjour patch

With a patch, SABnzbd will announce itself via Bonjour. That way, you can find SABnzbd's web interface easily on your LAN. No need to hassle with IP addresses and port numbers.

I've tested this patched SABnzbd on Ubuntu. Here's how to use it:

1. Make sure the plain SABnzbd is working on your system.
2. The "SABnzbd Host" under Config -> General should state 0.0.0.0 (or ::) so that SABnzbd listens on the LAN interface
3. Install an additional library: sudo apt-get install libavahi-compat-libdnssd1
4. Download the patched SABnzbd 0.6.10 here and unpack it. Go into that directory
5. Stop the plain SABnzbd if it is running
6. Start the patched SABnzbd called "SABnzbd-bonjour.py", which you can find in the unpacked directory

SABnzbd should now advertise itself via Bonjour. Install and start avahi-discover to see it. See the included screenshot.

If you want to see Bonjour services from within Chrome/Chromium or Firefox (on any OS), go to http://dnssd.me/ and install the DNSSD extension. This should work on Linux (with Avahi installed), Mac OS X, and Windows (with itunes installed). See the included screenshot for an example.

Some remarks about using this patched SABnzbd on other operating systems:

• Other Linux versions: it should work after you install the needed libraries for avahi and the avahi-compat stuff
• Unix versions (for example embedded on NAS devices): it all depends on the libraries
• Mac OS X: I guess the patched SABnzbd should work if you can get the plain SABnzbd-source-version working. Please give feedback
• Windows: I have no idea as I don't know how to run SABnzbd from source on Windows. If you're going to try this, first make sure itunes is installed

Feedback welcome in the comments

PS: there's very little IPv6 in this stuff, but it's quite network oriented, so I posted it here.

Easy NZB-downloading on Ubuntu 11.10 with nzbget via free IPv6-only Newsservers

Ubuntu 11.10 (also known as Oneiric Ocelot) has got the NZB-downloader nzbget in its repositories. Combined with IPv6 based on miredo, and the free IPv6-only Newsservers, downloading NZBs is easy and you don't need a newsserver account. Here's the howto:

Open a terminal and type:

sudo apt-get install nzbget miredo

zcat /usr/share/doc/nzbget/examples/nzbget.conf.example.gz > ~/.nzbget

nzbget -s  -o Server1.Host=weathergirl-ipv6.tele2.net 

The above will start the nzbget daemon.

Then, create a NZB, for example via http://binsearch.info/ and download it. Let's say its name is mynzb.nzb

Finally, open another terminal, add the NZB you want to download to nzbget's queue, for example: 

nzbget -A ~/Downloads/mynzb.nzb

Switch back to the 'daemon'-terminal, and you should see the nzgbet daemon downloading your request. It will end up in ~/download/dst/

If it doesn't work, check that your IPv6 is working; make sure you get an output like this:

ubuntu@ubuntu:~$ ping6 -c4 ipv6.google.com

PING ipv6.google.com(ey-in-x63.1e100.net) 56 data bytes

rtt min/avg/max/mdev = 25.801/93.545/205.635/74.216 ms

ubuntu@ubuntu:~$

Remarks:

• Instead of weathergirl-ipv6.tele2.net, you can use the other IPv6-only accountless newsserver: newszilla6.xs4all.nl
• If you want to use a newsserver that requires an account, use something like "nzbget -s  -o Server1.Host=your.newsserver.com -o Server1.Username=user -o Server1.Password=pass" in the 'daemon'-terminal
• The plain nzbget does not take care of rar and par. However, there's a postprocessing script somewhere in the intall. EDIT: see /usr/share/doc/nzbget/examples/postprocess-example.* 
• If you prefer a more GUI-like NZB-downloader, check out SABnzbd: http://sabnzbd.org/
• Older Ubuntu's haven't got nzbget in the standard repositories. However, there's a PPA: http://ppa.launchpad.net/volkris/ppa/ubuntu/pool/main/n/nzbget/

Happy downloading!

VMware Player blocks Teredo IPv6 on Windows 7

It seems VMware Player blocks Teredo IPv6 on Windows 7:

Teredo IPv6 was working on 'my' Windows 7. However, after installing VMware Player, all IPv6 connectivity was gone: "ipconfig" showed a lot of VMware interfaces, but no Teredo IPv6 anymore.

I'm now removing VMware Player, and immediately the Teredo IPv6 interface pops up again and http://test-ipv6.com/ tells me I have IPv6 connectivty again.

I wonder whether VMware has a good reason to disable/block IPv6, or it's just 'collateral damage' ...  

So for now: bye, bye VMware ... 

BTW: I wonder if VMware Player also blocks native IPv6.

Cable ISP Ziggo to provide IPv6 in "2012"

Interesting: Dutch Cable ISP "Ziggo" says it's going to provide IPv6 to it's cable customers in mid / end 2012. See https://www.ziggo.nl/#entertainment/nieuws/ziggo/ziggo/0/ziggo-en-het-nieuwe-internetprotocol-ipv6

Quotes:

• "Vanaf eind 2012 wordt bij bestaande klanten IPv6 toegevoegd. Nieuwe klanten krijgen dan direct IPv6."
• "Naar verwachting ondersteunt Ziggo medio 2012 het IPv6 protocol voor haar klanten, die een juiste huisinstallatie hebben."

Translation:

• As of end 2012 existing customer will get IPv6. New customers will then immediately get IPv6
• Mid 2012 Ziggo will support IPv6 for it's customers that have the correct CPE

Hopefully Ziggo can fulfill this promise.

Stream your Webcam over IPv6 using VLC

It's quite easy to stream your Webcam over IPv6. Here's the recipe for doing it on Ubuntu Linux:

1. Make sure VLC is installed ("sudo apt-get install vlc")
2. Make sure your webcam is connected
3. Make sure VLC can see your webcam: "vlc v4l2:///dev/video0" should show what your webcam sees.
4. Now start VLC as a streamer on port 4444 (or choose another free port above 1024) with this one command: 
   
   cvlc -vvv v4l2:///dev/video0  --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=128}:standard{access=http,mux=ogg,dst=[::]:4444}'
   
   
5. Find out the IPv6 address of your streaming machine, for example with ifconfig or via http://test-ipv6.com/ . Let's say it's 2001:888:aaa::1.
6. Still on the same machine, make sure you can watch the stream locally:
   
   vlc http://[ip6-localhost]:4444/
   
   vlc http://[2001:888:aaa::1]:4444/
   
   
7. Now, on another machine with IPv6 and VLC, you can watch your webcam stream with the same command above, so 
   
   vlc http://[2001:888:aaa::1]:4444/
   
   If you're more a GUI person, you can open VLC, and put the URL in Media -> Open Network Stream -> Network.
8. That's it.

Enabling IPv6 Privacy Extensions on Ubuntu Linux

On plain Ubuntu (and probably other Linux variants), the right hand part of the IPv6 address is based on your MAC address. As your MAC address is fixed and worldwide unique, you can be traced around the (IPv6) world based on your IPv6 (containing your MAC address). And often this is not wanted.

There's a solution for this called "IPv6 Privacy Extensions". It will give you semi-random IPv6 address, that will be changed regularly. The result is less tracking and more privacy.

Here's how to enable IPv6 Privacy Extensions on Ubuntu and probably other Linux variants:

As root, edit the file /etc/sysctl.conf, for example:

gksudo gedit /etc/sysctl.conf

In that file, add these lines:

net.ipv6.conf.wlan0.use_tempaddr = 2
net.ipv6.conf.eth0.use_tempaddr = 2
net.ipv6.conf.all.use_tempaddr = 2
net.ipv6.conf.default.use_tempaddr = 2

Save the file and exit the editor. Then reload your network, or just reboot.
(BTW: the above lines are based on interface eth0 and wlan0)

After the reboot, ifconfig will now show a second public IPv6 address on interface(s) that used to have only one public IPv6 address. On http://www.appelboor.com/ipv6.html and http://test-ipv6.com/ you should your new, "private" public IPv6 address.
