Anonabox Pro – Disable Wi-Fi

 in Other  tagged Anonabox / Anonabox Pro / disable / wi-fi / wifi by

The following video demonstrates how to disable the Wi-Fi on an  Anonabox Pro.

  1. Connect to the device via the LAN Ethernet port.
    It has a build DHCP server by default so you do not need to configure the IP.
    After you get connected, go to the default location of the device interface, which is http://192.168.19.84:1776/.
  2. After the interface loads, enter the root password and click on the Login button.
    (if you are using a brand new Anonabox or a box that was recently flashed then click on the Login button without entering a password (if you enter one, it will be ignored)).
  3. Then, go to the top menu Network and select the option Wireless
  4. At the new page, under the category Wireless Overview click on the Disable button.
  5. Finally, click on the OK button when you get the Really shut down network? confirmation box and wait for the changes to get applied, the image with the Wi-Fi logo will change to one that has a red stamp on it and right under the SSID field you will get the message Wireless is disabled or not associated.

To enable the WiFi, just repeat the steps above and click on the Enable button.

GNU/Linux Fedora 27: Prevent Network Manager from restarting after reboot 1

 in GNU/Linux  tagged fedora / NetworkManager / NetworkManager-wait-online / reboot / systemctl by

Recently we were working on a Fedora 27 GNU/Linux box where we needed to completely disable the Network Manager.
Initially, we just stopped the NetworkManager service and then disabled it thinking that it would be enough.
To our surprise after we rebooted the box, we noticed that the Network Manager was active again!

After some research we found out that another service called NetworkManager-wait-online was starting the NetworkManager as some sort of recovery mechanism.
So, in order to permanently block NetworkManager from starting on boot, we disabled NetworkManager-wait-online as well.

In the end our solution to disable the NetworkManager service came down to executing the following commands as root (or using sudo):


systemctl stop NetworkManager;
systemctl stop NetworkManager-wait-online;

systemctl disable NetworkManager;
systemctl disable NetworkManager-wait-online;

CONCEPTS

In a nutshell:

  • enabled is a service that is configured to start when the system boots
  • disabled is a service that is configured to not start when the system boots
  • active is a service that is currently running
  • inactive is a service that is currently stopped and may be disabled, but it can be started and become active

In much more detail:

systemd provides a dependency system between various entities called “units” of 12 different types. Units encapsulate various objects that are relevant for system boot-up and maintenance. The majority of units are configured in unit configuration files, whose syntax and basic set of options is described in systemd.unit(5), however some are created automatically from other configuration, dynamically from system state or programmatically at runtime. Units may be “active” (meaning started, bound, plugged in, …, depending on the unit type, see below), or “inactive” (meaning stopped, unbound, unplugged, …), as well as in the process of being activated or deactivated, i.e. between the two states (these states are called “activating”, “deactivating”). A special “failed” state is available as well, which is very similar to “inactive” and is entered when the service failed in some way (process returned error code on exit, or crashed, or an operation timed out). If this state is entered, the cause will be logged, for later reference. Note that the various unit types may have a number of additional substates, which are mapped to the five generalized unit states described here.
