vagrant-bcctools

I created this repo because it turns out that playing with bcctools on macOS is a PITA.

You can't use the following:

  • the docker image mentioned in the bcc repo's QUICKSTART.md because that's expected a Linux Docker host.
  • the vagrant repo is 4 years old and doesn't appear to play nice with a modern version of Vagrant.

usage

  • We'll assume you've installed VirtualBox and Vagrant.

Setup the vagrant session (this will take a while).

make setup

Once vagrant session is up, you can verify your install using the "hello world" python script:

vagrant ssh
sudo /usr/share/doc/bpfcc-tools/examples/hello_world.py

In another terminal session

vagrant ssh

In the first terminal session you'll see something similar as the ssh session begins and clone syscall is triggered.

Running BCC tools

The tools are installed in /sbin (/usr/sbin in Ubuntu 18.04) with a -bpfcc extension. More information can be found in the BCC install docs.

After vagrant ssh, you can run any tool such as execsnoop by calling it directly or from the /usr/sbin directory. e.g.

sudo execsnoop-bpfcc

sudo /usr/sbin/execsnoop-bpfcc
