NAME

6       ConnMan - network management daemon
7

SYNOPSIS

9       connmand [--version|--help]
10
11       connmand  [-c  file]  [-d [file[,...]]] [-i interface[,...]] [-I inter‐
12       face[,...]] [-W driver[,...]] [-p plugin[,...]] [-P plugin[,...]]  [-n]
13       [-r]

DESCRIPTION

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

OPTIONS

26       The following options are supported:
27
28       -v, --version
29              Print the ConnMan software version and exit.
30
31       -h, --help
32              Print ConnMan's available options and exit.
33
34       -c file, --config=file
35              Specify configuration file to set up various settings for  Conn‐
36              Man.    If  not  specified,  the  default  value  of  /etc/conn‐
37              man/main.conf is used.  See connman.conf(5) for more information
38              on  configuration  file.  The use of config file is optional and
39              sane default values are used if config file is missing.
40
41       -d [file[,...]], --debug[=file[,...]]
42              Sets how much information ConnMan sends to the  log  destination
43              (usually  syslog's  "daemon" facility).  If the file options are
44              omitted, then debugging information from all  the  source  files
45              are printed. If file options are present, then only debug prints
46              from that source file are printed. Example:
47
48                  connmand --debug=src/service.c,plugins/wifi.c
49
50       -i interface[,...], --device=interface[,...]
51              Only manage these network interfaces.  By  default  all  network
52              interfaces are managed.
53
54       -I interface[,...], --nodevice=interface[,...]
55              Never manage these network interfaces.
56
57       -p plugin[,...], --plugin=plugin[,...]
58              Load  these plugins only. The option can be a pattern containing
59              "*" and "?" characters.
60
61       -P plugin[,...], --noplugin=plugin[,...]
62              Never load these plugins. The option can be a pattern containing
63              "*" and "?" characters.
64
65       -W driver[,...], --wifi=driver[,...]
66              Wifi  driver  that  WiFi/Supplicant  should use. If this flag is
67              omitted, then the value "nl80211,wext" is used by default.
68
69       -n, --nobacktrace
70              Don't print out backtrace information.
71
72       -n, --nodaemon
73              Do not daemonize. This is useful for debugging, and directs  log
74              output to the controlling terminal in addition to syslog.
75
76       -r, --nodnsproxy
77              Do  not  act  as a DNS proxy. By default ConnMan will direct all
78              DNS traffic to itself by  setting  nameserver  to  127.0.0.1  in
79              resolv.conf(5)  file.   If this is not desired and you want that
80              all programs call directly some DNS server, then you can use the
81              --nodnsproxy  option.   If  this option is used, then ConnMan is
82              not able to cache the DNS queries because the DNS traffic is not
83              going  through  ConnMan  and  that  can cause some extra network
84              traffic.
