ConnMan - network management daemon
connmand [-c file]
[-d [file[,...]]] [-i interface[,...]]
[-I interface[,...]] [-W driver[,...]]
[-p plugin[,...]] [-P plugin[,...]] [-n]
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.
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
- -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
connmanctl(1), connman.conf(5), connman-service.config(5), connman-vpn(8)
- -i interface[,...], --device=interface[,...]
- Only manage these network interfaces. By default all network interfaces
- -I interface[,...], --nodevice=interface[,...]
- Never manage these network interfaces.
- -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. 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
