How to build on Ubuntu 14.04?


First of all you need to have CONFIG_NET_DROP_MONITOR enabled in your kernel

Install dependencies:

sudo apt-get install -y libnl-3-dev libnl-genl-3-dev binutils-dev libreadline6-dev

Then clone repo, cd to src folder and run make.

And finally run tool: ./dropwatch -l kas

You can’t perform that action at this time.
