Deploy

To Compiling Uranus, execute following command:

git clone ..
make

To deploy Uranus on kubernetes, execute following command:

kubectl apply -f https://raw.githubusercontent.com/cylonchau/firewalld-gateway/main/deploy/deployment.yaml

To run Uranus on docker, execute following command:

docker run -d --rm  cylonchau/uranus

if you think update you dbus-daemon verion to lasest, can use dbus.spec make your package.

• v2 permanent resource.
• v3 Asynchronous batck opreation.

FAQ

Why not use ssh or ansible tools.

Because D-Bus support remotely and firewalld implemented full D-Bus API, so we can batch manage iptables rules via firealld.

How diffrence your project and other

firewall gateway implemented full dbus API convert to HTTP API, so can control thousands of machine via gateway. And ohter project update iptables via agent scripts. or only run on one machines.

Is enable D-Bus remotely safe?

We can open D-Bus port only accpet gateway's IP, so is safed

default if you machine hacked, enable of disable D-Bus remote, it doesn't make any sense. Because hacker can run any command on your machine.

If you machine Is safe, so we can through open D-Bus port only accpet gateway's IP, so can management iptables rules via gateway and UI

For example

• The layer 1, you can add iptables rule restrict dbus tcp port.
• The layer 2, you can use dbus ACL restrict request.

To edit /etc/dbus-1/system.conf, example.

<policy context="default">
    <deny receive_path="/org/fedoraproject/FirewallD1" /> <!-- restrict all request -->
    <allow user="root" />
    <allow own="com.github.cylonchau.Uranus" /> <!-- allow uranus resiger to dbus-daemon -->
    <!-- if requseter is com.github.cylonchau.Uranus and request path is /org/fedoraproject/FirewallD1, then allow  -->
    <allow receive_sender="com.github.cylonchau.Uranus" receive_path="/org/fedoraproject/FirewallD1" />
</policy>
