Speed Limit Randomiser

[OOPMan]

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
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 4 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 6.5 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 3 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 15 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 20 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 2 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 1 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)
Setting new speed to 4 Mbps
ok

Now sleeping ... (Press 'CTRL C' to stop)

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

Code: Select all
