SuperShaper-SOHO is a traffic shaping setup for DSL connections which prioritizes VoIP and interactive traffic, and makes sure P2P traffic doesn't saturate your uplink. With this setup you should get very low latency on interactive traffic (e.g. SSH) while having e.g. your cloud backup fully saturate your upstream. You should no longer need to set any upload limits in your applications.

You might've heard references here and there to the LARTC Wondershaper script which used the even older CBQ scheduler. You could think of this as a modern and improved replacement for that script.


  • iproute2 (tc command)
  • Linux kernel with support for HFSC and fq_codel schedulers (3.6 should work, but use 3.12 or later for best performance)

Ubuntu 14.04 is known to work and is the author's primary development platform. It's been in daily use by the author for a number of years.


Modify the variables on top of supershaper.init and copy this file to /etc/init.d/supershaper. Make sure that the file has executable bits set. Then make sure it starts up automatically at startup.

On Ubuntu this is usually done like this:

$ sudo cp supershaper.init /etc/init.d/supershaper
$ sudo chown root:root /etc/init.d/supershaper
$ sudo chmod 0755 /etc/init.d/supershaper
$ sudo update-rc.d supershaper defaults

If you're using a PPP-based connection you might also want to ensure it is started every time your connection is established by symlinking it into /etc/ppp/ip-up.d/. There shouldn't be any need to run it when the connection is ended, as queueing disciplines are automatically removed when an interface is destroyed.

On Ubuntu this is usually done like this:

$ sudo ln -sf /etc/init.d/supershaper /etc/ppp/ip-up.d/supershaper
