How can I tell Firewall to allow incoming connections for Python.app running Django

Question

Each time I run my Django development server, I get a dialog to allow incoming connections.

No matter what I do :

• Click Allow in the dialog box
• Add to the Firewall via the OS X GUI (both real and venv python executables are allowed, and also the Python.app
• Self-sign the executable (see http://darklaunch.com/2014/02/02/fix-do-you-want-the-application-python-to-accept-incoming-network-connections)

OS X still systematically ask me to allow incoming connection.

It's not just annoying, it's impossible to work with my IDE which restart the dev server after each code change.

I have to either turn off the firewall, or change my IDE configuration, both are bad solutions.

How can I permanently add the script in my firewall allowed apps?

I'm running Maverick 10.9.4

Answer 1

Signing the python application, using the instruction in the answer to this question, worked for me.

Answer 2

You can manually configure the firewall to unblock a port (i.e. 8080).

You'll need to open /etc/pf.conf in a text editor and add:

pass in proto tcp from any to any port 8080

to the end of the file (for port 8080, adjust to suit your needs).

Then restart your computer.

If that doesn't work run:

$ sudo pfctl -vnf /etc/pf.conf

to see if you get an error. If so fix.

Then restart again.

Should work.
