1 IP Configuration Handling 2 ************************* 3 4 5 IP basics 6 ========= 7 8 Layer 3 configuration state is managed on a per-device basis. When 9 a device is connected, it will have an IPConifg record associated with 10 it. In addition, connected services will have an "IPConfig" property 11 which will contain the path to this record. These properties of the 12 IPConfig record represent the current state of connectivity of the 13 device. 14 15 IPConfig hierarchy 16 ================== 17 18 Service org.chromium.flimflam 19 Interface org.chromium.flimflam.IPConfig 20 Object path [variable prefix]/{ipconfig0,ipconfig1,...} 21 22 Methods dict GetProperties() 23 24 Return properties for the IPConfig object. See 25 the properties section for available properties. 26 27 void Refresh() 28 29 Cause the IP configuration to be refreshed. In 30 the case of DHCP configurations, the lease is 31 renewed, and any Static IP configuration from 32 the service is re-applied. 33 34 Signals PropertyChanged(string name, variant value) 35 36 This signal indicates a changed value of the given 37 property. 38 39 Properties string Address [readonly] 40 41 The Layer 3 address expressed in the dotted-quad format 42 for IPv4 and any allowed format for IPv6 (as specified 43 for inet_pton(3)). 44 45 string Broadcast [readonly] 46 47 The Layer 3 broadcast address specified as per Address. 48 49 string DomainName [readonly] 50 51 The DNS domain name to use in building FQDN queries. 52 53 string Gateway [readonly] 54 55 The Layer 3 address gateway address specified as 56 per Address. 57 58 string Method [readonly] 59 60 The method by which Layer 3 state is managed. 61 62 Possible methods are: 63 "ipv4" (fixed IPv4 network state) 64 "ipv6" (fixed IPv6 network state) 65 "dhcp" (IPv4 state setup using DHCP) 66 "bootp" (IPv4 state setup using BOOTP) 67 "zeroconf" (IPV4 state setup using ZeroConf) 68 "dhcp6" (IPv6 state setup using DHCP6) 69 "ppp" (IPv4 state setup using PPP) 70 "vpn" (IPv4 state setup using VPN) 71 72 int32 Mtu [readonly] 73 74 The maximum transmit unit (MTU) in bytes. 75 76 array{string} NameServers [readonly] 77 78 The Layer 3 addresses of DNS domain name servers to 79 use for DNS requests. 80 81 string PeerAddress [readonly] 82 83 The Layer 3 address associated with the destination 84 endpoint of a point-to-point link. This value is 85 specified as per Address. 86 87 int32 Prefixlen [readonly] 88 89 The number of bits in a Layer 3 address that are 90 part of the network address. For IPv4 networks this 91 corresponds to the length of the network mask; e.g. 92 a netmask of 255.255.255.0 has a prefixlen of 24 93 (note arbitrary CIDR masks are not supported.) 94 95 array{uint8} VendorEncapsulatedOptions [readonly] 96 97 Server-provided value for the DHCP option 43 98 value. Its interpretation varies based on 99 the DHCP server. 100 101 string WebProxyAutoDiscoveryUrl [readonly] 102 103 The Web Proxy Auto-Discovery URL for this network 104 as reported over DHCP. 105
