acc-fwu

acc-firewall_updater

A tool to automatically update the Akamai Connected Cloud (ACC) / Linode firewall rules to allow your IP

Description

acc-fwu is a command-line tool to automatically update Linode/ACC firewall rules with your current IP address. This is particularly useful for dynamically updating firewall rules to allow access from changing IP addresses, like when you visit the gym or you're sat in an airport.

Installation

You can install the package via pip:

pip install acc-fwu

Alternatively, you can install it directly from the source:

git clone https://github.com/johnybradshaw/acc-firewall_updater.git
cd acc-firewall_updater
pip install --use-pep517 .

Usage

First-time Setup

The first time you use acc-fwu, you’ll need to provide your Linode/ACC Firewall ID and optionally the label for the rule you want to create or update:

acc-fwu --firewall_id <FIREWALL_ID> --label <RULE_LABEL>

For example:

acc-fwu --firewall_id 123456 --label "Allow-My-Current-IP"

This command will do two things:

1. It will create or update the firewall rule with your current public IP address.
2. It will save the firewall_id and label to a configuration file (~/.acc-fwu-config) for future use.

Subsequent Usage

After the initial setup, you can simply run acc-fwu without needing to provide the firewall_id and label again:

acc-fwu

This will:

1. Load the saved firewall_id and label from the configuration file.
2. Update the firewall rule with your current public IP address.

Updating the Configuration

If you need to change the firewall_id or label, you can do so by running:

acc-fwu --firewall_id <NEW_FIREWALL_ID> --label <NEW_RULE_LABEL>

This will update the configuration file with the new values.

Removing Firewall Rules

You can remove the firewall rule by running:

acc-fwu --remove

Configuration File

The acc-fwu tool saves the firewall_id and label in a configuration file located at ~/.acc-fwu-config. This file is automatically managed by the tool, so you generally won’t need to edit it manually.
