Intermittent network disconnection on Ubuntu 22.04 when ITP is enabled
ITP relies on systemd to direct traffic or internal resources for Linux based systems, including Ubuntu 22.04. Banyan has identified times when internet connectivity is disrupted on Ubuntu 22.04 devices when rapidly switching between blocked sites (as configured by ITP policies) and non-blocked sites.
The root cause analysis determined that Ubuntu 22.04’s systemd is not the latest version of systemd, and this is a known issue with the version packaged with Ubuntu 22.04. A bug report has been filed here: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2030505
- Ubuntu 22.04 registered devices with ITP enabled.
Systemd will resume working properly after 3-5 mins of waiting; No additional steps are required.
ITP initiation error in orgs that have DNS interceptors listening on their DNS port as well as ITP enabled
When admins who have ITP enabled in their org run DNS interceptors that listens on their DNS ports, ITP doesn’t initiate (i.e., the
banyanwgs is unable to bind to its port and hence does not take over DNS on the device). Currently, there is no indication (in the logs or Healthcheck) that ITP isn’t working, and the ITP health check erroneously reports that it is working.
Ensure that the service that is using port 53 is not running when you start ITP.
Verify using the following command:
sudo lsof -i -P -n | grep ":53$"
