Hi all

So, I have a thorny problem. My ISP attempts to detect abuse in two ways:

1: Usage of VPNs to circumvent shaping
2: Downloading at line or near-line speeds for extended periods

Now, I realise you guys can't do anything about point 1.

However, it strikes me that something could be done about point 2. Of course, a simple solution would be for me to simply halve my max download speed in SABNZBD.

But it would be cool if there were a feature such that I could tell SABNZBD+ to, for example, maintain an average max download speed of X and then SABNZBD+ varies the
actual max download speed such that an average max speed of X is maintained as best as possible while actual max speeds from second to second vary up and down in a
pseudo-random fashion that would hopefully throw a spanner in the traffic analysis works.

Anyway, just an idea :-)

Setup a schedule in SABnzbd for changing the speed.
If you're any good at scripting, write a Python or Perl program
to send speed changes to SABnzbd through its API.

I felt like some API programming, so I created exactly that. :)

I've included the python script.

@OOPman: change the line with "apikey" to your own apikey. You can also change the speed settings if you want. Then run with:

Code: Select all

python sabspeed-mini.py

Output of the script:

Code: Select all

sander@lifebook:~/sabspeedrandomizer$ python sabspeed-mini.py 
Setting new speed to 1 Mbps

... and this is what SABnzbd says, so the proof it's working:
