Changing default listening port
===============================

The default listening port for the tangd service is 80, the usual HTTP
port. If this causes a collision with other services, use

    systemctl edit tangd.socket

to create an override.

To activate any changes:

    systemctl restart tangd.socket

As an example, the following content will

* disable listening on port 80
* enable listening on port 81 instead

    [Socket]
    ListenStream=
    ListenStream=81

See systemd.socket(5) for more options.
