Try it

$ butterfly

A new tab should appear in your browser. Then type

$ butterfly help

To get an overview of butterfly features.

Run it as a server

$ butterfly.server.py --host=myhost --port=57575

Or with login prompt

$ butterfly.server.py --host=myhost --port=57575 --login

Or with PAM authentication (ROOT required)

# butterfly.server.py --host=myhost --port=57575 --login --pam_profile=sshd

You can change sshd to your preferred PAM profile.

The first time it will ask you to generate the certificates (see: here)

Run it with systemd (linux)

Systemd provides a way to automatically activate daemons when needed (socket activation):

$ cd /etc/systemd/system
$ curl -O https://raw.githubusercontent.com/paradoxxxzero/butterfly/master/butterfly.service
$ curl -O https://raw.githubusercontent.com/paradoxxxzero/butterfly/master/butterfly.socket
$ systemctl enable butterfly.socket
$ systemctl start butterfly.socket

Don't forget to update the /etc/butterfly/butterfly.conf file with your server options (host, port, shell, ...) and to install butterfly with the [systemd] flag.
