+
+
+Functionality and features
+==========================
+
+The following features are built-in into Connection Manager:
+ - Generic plugin infrastructure
+ - Device and network abstraction (with basic storage support)
+ - IPv4, IPv4-LL (link-local) and DHCP
+ - IPv6, DHCPv6 and 6to4 tunnels
+ - Advanced routing and DNS configuration
+ - Built-in DNS proxy and intelligent caching
+ - Built-in WISPr hotspot logins and portal detection
+ - Time and timezone configuration (manual and automatic with NTP)
+ - Proxy handling (manual and automatic with WPAD)
+ - Tethering support (USB, Bluetooth and WiFi AP mode)
+ - Detailed statistics handling (home and roaming)
+
+Various plugins can be enabled for networking support:
+ - Ethernet plugin
+ - WiFi plugin with WEP40/WEP128 and WPA/WPA2 (personal and enterprise)
+ - Bluetooth plugin (using BlueZ)
+ - 2G/3G/4G plugin (using oFono)
+
+Also plugins with additional features are available:
+ - Loopback interface setup
+ - PACrunner proxy handling
+ - PolicyKit authorization support
+
+
+Compilation and installation
+============================
+
+In order to compile Connection Manager you need following software packages:
+ - GCC compiler
+ - GLib library
+ - D-Bus library
+ - IP-Tables library
+ - GnuTLS library (optional)
+ - PolicyKit (optional)
+
+To configure run:
+ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
+
+Configure automatically searches for all required components and packages.
+
+To compile and install run:
+ make && make install
+
+
+Configuration and options
+=========================
+
+For a working system, certain configuration options need to be enabled:
+
+ --disable-ethernet
+
+ Disable support for Ethernet network cards
+
+ By default Ethernet technology support is built-in and
+ enabled. This option can be used to build a small daemon
+ for a specific system if Ethernet support is not required.
+
+ --disable-wifi
+
+ Disable support for WiFi devices
+
+ By default WiFi technology support is built-in and
+ enabled. This option can be used to build a small daemon
+ for a specific system if WiFi support is not required.
+
+ It is safe to build a daemon with WiFi support and no
+ running wpa_supplicant. The start of wpa_supplicant is
+ automatically detected and only a runtime dependency. It
+ is not needed to build ConnMan.
+
+ --disable-bluetooth
+
+ Disable support for Bluetooth devices
+
+ By default Bluetooth technology support is built-in and
+ enabled. This option can be used to build a small daemon
+ for a specific system if Bluetooth support is not required.
+
+ It is safe to build a daemon with Bluetooth support and no
+ running bluetoothd. The start of bluetoothd is automatically
+ detected and only a runtime dependency. It is not needed to
+ build ConnMan.
+
+ --disable-ofono
+
+ Disable support for cellular 2G/3G/4G devices
+
+ By default oFono technology support is built-in and
+ enabled. This option can be used to build a small daemon
+ for a specific system where oFono is not used.
+
+ It is safe to build a daemon with oFono support and no
+ running ofonod. That start of ofonod is automatically
+ detected and only a runtime dependency. It is not needed to
+ build ConnMan.
+
+ --disable-dundee
+
+ Disable support for Bluetooth DUN devices
+
+ By default Bluetooth DUN technology (dundee) support is
+ built-in and enabled. This option can be used to build a
+ small daemon for a specific system where dundee is not used.
+
+ It is safe to build a daemon with dundee support and no
+ running dundee. That start of dundee is automatically
+ detected and only a runtime dependency. It is not needed to
+ build ConnMan.
+
+ --disable-pacrunner
+
+ Disable support for PACrunner proxy handling
+
+ By default PACrunner support is built-in and enabled. This
+ option can be used to build a small daemon for a specific
+ system where PACrunner is not used.
+
+ It is safe to build a daemon with PACrunner support and no
+ pacrunner daemon. It will detect and start a PACrunner
+ process if needed at runtime. The presence is not needed
+ to build ConnMan.
+
+ --disable-loopback
+
+ Disable setup of loopback device
+
+ For distributions with a really minimal init system and no
+ networking scripts this can take care of setting up the
+ loopback device and enabling it.
+
+ It is safe to leave this selected even if networking
+ scripts are in place. It detects an already configured
+ loopback device and leaves it as it is.
+
+ --disable-wispr
+
+ Disable support for WISPr hotspot logins
+
+ For systems with really minimal memory requirements, this
+ will disable the support for WISPr hotspot logins. The code
+ for WISPr will be still compiled into the daemon, but its
+ requirement on GnuTLS for secure connections will be lifted.
+
+ The missing GnuTLS support shrinks the memory requirements
+ by about 30% and for systems that are more stationary and do
+ not log into hotspots this might be a better trade off.
+
+ Disabling WISPr support is not disabling the portal detection
+ support. A portal will still be detected, but instead of being
+ asked for login credentials, the request for a browser session
+ will be made through the agent.
+
+ --enable-polkit
+
+ Enable support for PolicyKit authorization
+
+ This allows to check every D-Bus access against a security
+ policy and so restrict access to certain functionality.
+
+ --enable-nmcompat
+
+ Enable support for NetworkManager compatibility interfaces
+
+ This allows to expose a minimal set of NetworkManager
+ interfaces. It is useful for systems with applications
+ written to use NetworkManager to detect online/offline
+ status and have not yet been converted to use ConnMan.
+
+
+wpa_supplicant configuration
+============================
+
+In order to get wpa_supplicant and Connection Manager working properly
+together you should edit wpa_supplicant .config file and set:
+
+CONFIG_WPS=y
+CONFIG_AP=y
+CONFIG_CTRL_IFACE_DBUS_NEW=y
+
+and, add:
+
+CONFIG_BGSCAN_SIMPLE=y
+
+This last option will enable the support of background scanning while being
+connected, which is necessary when roaming on wifi.
+
+It is recommended to use wpa_supplicant 0.8.x or 1.x or later.
+
+
+VPN
+===
+
+In order to compile pptp and l2tp VPN plugins, you need ppp development
+package.
+
+To run l2tp you will need
+ - xl2tpd, http://www.xelerance.com/services/software/xl2tpd
+
+To run pptp you will need
+ - pptp client, http://pptpclient.sourceforge.net
+
+Both l2tp and pptp also need pppd.
+
+
+OpenVPN
+=======
+
+Up to version 2.2 of OpenVPN, pushing additional routes from the
+server will not always work. Some of the symptons are that additional
+routes will not be set by ConnMan if the uplink is a cellular
+network. While the same setup works well for a WiFi or ethernet
+uplink.
