Advanced configuration interface ******************************** Configuration basics ==================== The default configuration method for all servers is automatic or something like DHCP. In almost every case that should be just good enough, but if it is not, Connection Manager supports manual configuration for Ethernet and IP settings. Configuration interface ======================= Every service contains two properties. One represents the current active configuration and the other one allows manual configuration via the user. For IPv4 they are named "IPv4" and IPv4.Configuration". [ /profile/default/wifi_001122334455_42696720696e204a6170616e_managed_psk ] Type = wifi Name = Big in Japan Mode = managed Strength = 82 Security = rsn Favorite = true State = ready IPv4.Configuration = { Method=dhcp } IPv4 = { Netmask=255.255.255.0 Method=dhcp Address=192.168.1.198 } The above WiFi network shows how the default configuration would look like with a connected service. The configuration method is DHCP and the current IP address is 192.168.1.198. The "IPv4" property is read-only and will emit PropertyChanged signals in case the IP address of this interface changes. The "IPv4.Configuration" property is read-write and allows changes. For example to use a static IP configuration this call could be used: service.SetProperty("IPv4.Configuration", { "Method": "manual", "Address": "192.168.1.100", "Netmask": "255.255.255.0" }) The configuration itself is a dictionary with various fields. Not all of them need to present. A lot of combinations are valid. For example the "Method" field has valid settings of "off", "fixed", "manual" and "dhcp". The "fixed" value however can not be set by any user program. It is an internal value that some 3G cards require. Switching to "off" will remove and IP configuration from the interface. The "manual" method allows for static address configuration. And "dhcp" will use DHCP to retrieve all required information automatically. With a manual configuration, the fields "Address" and "Netmask" should be given. In case "Netmask" is left out, the best netmask will be calculated. The "Gateway" field can be used to indicate the default route/gateway for this interface.
