       main.conf - ConnMan configuration file


       where <SYSCONFDIR> depends on your distribution or build.


       main.conf  is  a configuration file for ConnMan. The configuration file is optional but it
       can be used to set up various aspects of ConnMan's behavior. The location of the file  may
       be changed through use of the "--config=" argument for connman (8).


       The  configuration  file  format  is key file format.  It consists of sections (groups) of
       key-value pairs.  Lines beginning with a '#' and  blank  lines  are  considered  comments.
       Sections  are started by a header line containing the section enclosed in '[' and ']', and
       ended implicitly by the start of the next section or the end of the file.  Each  key-value
       pair must be contained in a section.

       Description of sections and available keys follows:

       This section is the only mandatory section of the configuration file.

              Set  input  request  timeout.  Default  is  120 seconds The request for inputs like
              passphrase will timeout after certain amount of time. Use this setting to  increase
              the value in case of different user interface designs.

              Set  browser  launch  timeout.  Default  is 300 seconds The request for launching a
              browser for portal pages will timeout  after  certain  amount  of  time.  Use  this
              setting to increase the value in case of different user interface designs.

              Enable  background scanning. Default is true.  Background scanning will start every
              5 minutes unless the scan list is empty. In that case, a simple  backoff  mechanism
              starting from 10s up to 5 minutes will run.

              List  of Fallback timeservers separated by ",".  These timeservers are used for NTP
              sync when there are no timeserver set by the user or by  the  service.   These  can
              contain mixed combination of fully qualified domain names, IPv4 and IPv6 addresses.

              List  of  fallback nameservers separated by "," appended to the list of nameservers
              given by the service. The nameserver entries must be in numeric format, host  names
              are ignored.

              List  of  technologies  that  are  marked  autoconnectable by default, separated by
              commas ",". The default value for this entry when empty is  ethernet,wifi,cellular.
              Services  that  are  automatically  connected  must  have  been set up and saved to
              storage beforehand.

              List of preferred technologies from the most preferred one to the  least  preferred
              one  separated by commas ",".  Services of the listed technology type will be tried
              one by one in the order given, until one of them gets connected  or  they  are  all
              tried.  A  service  of  a  preferred  technology type in state 'ready' will get the
              default route when compared to another preferred type further down  the  list  with
              state  'ready'  or  with  a non-preferred type; a service of a preferred technology
              type in state 'online' will get the default route when compared to  either  a  non-
              preferred type or a preferred type further down in the list.

              List  of blacklisted network interfaces separated by ",".  Found interfaces will be
              compared to the list and will not be handled by connman, if their first  characters
              match any of the list entries. Default value is vmnet,vboxnet,virbr.

              Allow  connman  to  change  the  system hostname. This can happen for example if we
              receive DHCP hostname option.  Default value is true.

              Keep only a single connected  technology  at  any  time.  When  a  new  service  is
              connected  by the user or a better one is found according to PreferredTechnologies,
              the new service is kept connected and all the other previously  connected  services
              are  disconnected.  With  this  setting  it  does not matter whether the previously
              connected services are in 'online' or 'ready' states, the newly  connected  service
              is  the  only one that will be kept connected. A service connected by the user will
              be used until going out of network coverage. With this setting enabled applications
              will notice more network breaks than normal. Default value is false.

              List  of  technologies  that are allowed to enable tethering separated by ",".  The
              default value is wifi,bluetooth,gadget. Only those  technologies  listed  here  are
              used  for  tethering.  If  one wants to tether ethernet, then add "ethernet" in the
              list.  NOTE that if ethernet tethering is enabled, then a DHCP server is started on
              all  ethernet  interfaces. Tethered ethernet should never be connected to corporate
              or home network as it will disrupt normal operation of these networks. Due to  this
              ethernet  is not tethered by default. Do not activate ethernet tethering unless you
              really know what you are doing.

              Restore earlier tethering status when returning from offline  mode,  re-enabling  a
              technology, and after restarts and reboots.  Default value is false.
