How to do equivalent of nmcli connection up 'Wired connection 2'?

[ict-rhys-williams]

Hi,

I can set the IP etc on my interface and apply to the bus:

        from sdbus_async.networkmanager import NetworkManagerSettings, NetworkConnectionSettings

# Ideally want to look up by device eth1
        connection_paths = await NetworkManagerSettings().get_connections_by_id(self.connection_id)
        if not connection_paths:
            raise Exception(f"No connection found with id {self.connection_id}")

        connection_manager = NetworkConnectionSettings(connection_paths[0])
        connection_profile = await connection_manager.get_profile()
        settings = connection_profile.to_settings_dict()
        
        return settings, connection_manager

async def _network_linux_apply(self):
        from sdbus_async.networkmanager.settings import ConnectionProfile
        settings, connection_manager = await self._network_linux_profile()  
        ipv4 = settings['ipv4']
        ipv4['address-data'][0]['address'] = self.ap_ip
        ipv4['address-data'][0]['prefix'] = sum([bin(int(x)).count('1') for x in self.netmask.split('.')])
        ipv4['gateway'] = self.gateway
        ipv4['dns-data'][0] = self.dns 
        new_connection_profile = ConnectionProfile.from_settings_dict(settings)
        await connection_manager.update(new_connection_profile.to_dbus())
        await connection_manager.save()

However to get the device to use the new IP, I have to issue nmcli connection up 'Wired connection 2'

How can this command by sent via the python AP?

Thanks in advance

Hello @ict-rhys-williams

I believe you will need to activate the connection from the main NetworkManager object.

So it should be something like this await nm.activate_connection(connection_paths[0], "/", "/"). The nm is the NetworkManager main object.

If the connection is already running you will need to deactivate it first and then activate.

Thanks so much .. that did the job! You don't need to deactivate on the linux I'm using.

Here is the update code should anyone else need it:

    async def _network_linux_apply(self):
        from sdbus_async.networkmanager.settings import ConnectionProfile
        settings, connection_manager = await self._network_linux_profile()  
        ipv4 = settings['ipv4']
        ipv4['address-data'][0]['address'] = self.ap_ip
        ipv4['address-data'][0]['prefix'] = sum([bin(int(x)).count('1') for x in self.netmask.split('.')])
        ipv4['gateway'] = self.gateway
        ipv4['dns-data'][0] = self.dns 
        new_connection_profile = ConnectionProfile.from_settings_dict(settings)
        await connection_manager.update(new_connection_profile.to_dbus())

        from sdbus_async.networkmanager import NetworkManagerSettings, NetworkManager
        connection_paths = await NetworkManagerSettings().get_connections_by_id(self.connection_id)
        await nm.activate_connection(connection_paths[0])
