NAME

       ConnMan - network management daemon

SYNOPSIS

       connmand [--version|--help]

       connmand  [-c  file]  [-d [file[,...]]]  [-i  interface[,...]]  [-I  interface[,...]]  [-W
       driver[,...]] [-p plugin[,...]] [-P plugin[,...]] [-n] [-r]

DESCRIPTION

       The ConnMan provides a daemon for managing internet connections within devices running the
       Linux  operating  system.  The Connection Manager is designed to be slim and to use as few
       resources as possible.  It is a fully modular system that can be extended,  through  plug-
       ins, to support all kinds of wired or wireless technologies.  Also, configuration methods,
       like DHCP and domain name resolving, are implemented using plug-ins.  The plug-in approach
       allows for easy adaption and modification for various use cases.

OPTIONS

       The following options are supported:

       -v, --version
              Print the ConnMan software version and exit.

       -h, --help
              Print ConnMan's available options and exit.

       -c file, --config=file
              Specify  configuration  file  to  set  up  various  settings  for  ConnMan.  If not
              specified,  the   default   value   of   /etc/connman/main.conf   is   used.    See
              connman.conf(5)  for more information on configuration file. The use of config file
              is optional and sane default values are used if config file is missing.

       -d [file[,...]], --debug[=file[,...]]
              Sets how much information ConnMan sends to the log  destination  (usually  syslog's
              "daemon"  facility).   If  the file options are omitted, then debugging information
              from all the source files are printed. If file options are present, then only debug
              prints from that source file are printed. Example:

                  connmand --debug=src/service.c,plugins/wifi.c

       -i interface[,...], --device=interface[,...]
              Only  manage  these  network  interfaces.  By  default  all  network interfaces are
              managed.

       -I interface[,...], --nodevice=interface[,...]
              Never manage these network interfaces. The option can be a pattern  containing  "*"
              and "?" characters.

       -p plugin[,...], --plugin=plugin[,...]
              Load  these  plugins  only.  The  option  can  be  a pattern containing "*" and "?"
              characters.

       -P plugin[,...], --noplugin=plugin[,...]
              Never load these plugins. The option can  be  a  pattern  containing  "*"  and  "?"
              characters.

       -W driver[,...], --wifi=driver[,...]
              Wifi  driver  that  WiFi/Supplicant  should  use. If this flag is omitted, then the
              value "nl80211,wext" is used by default.

       -n, --nobacktrace
              Don't print out backtrace information.

       -n, --nodaemon
              Do not daemonize. This is useful for debugging,  and  directs  log  output  to  the
              controlling terminal in addition to syslog.

       -r, --nodnsproxy
              Do  not  act  as  a  DNS  proxy or support external DNS resolving. Depending on how
              ConnMan is compiled, it will by default direct all DNS traffic to itself by setting
              nameserver  to  127.0.0.1  in  resolv.conf(5)  file  or  leave DNS management to an
              external entity, such as systemd-resolved. If this is not desired and you want that
              all  programs  call  directly  some  DNS  server, then you can use the --nodnsproxy
              option. ConnMan then figures out the DNS server and search domain  on  startup  and
              sets  them  in  resolv.conf(5). If this option is used, then ConnMan is not able to
              cache the DNS queries because the DNS traffic is not going through ConnMan and that
              can cause some extra network traffic.
