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.
