Description

The NMSettingIP4Config object is a NMSetting subclass that describes properties related to IPv4 addressing, routing, and Domain Name Service.

NMSettingIP4Config has few properties or methods of its own; it inherits almost everything from NMSettingIPConfig.

NetworkManager supports 5 values for the “method” property for IPv4. If "auto" is specified then the appropriate automatic method (DHCP, PPP, etc) is used for the interface and most other properties can be left unset. If "link-local" is specified, then a link-local address in the 169.254/16 range will be assigned to the interface. If "manual" is specified, static IP addressing is used and at least one IP address must be given in the "addresses" property. If "shared" is specified (indicating that this connection will provide network access to other computers) then the interface is assigned an address in the 10.42.x.1/24 range and a DHCP and forwarding DNS server are started, and the interface is NAT-ed to the current default network connection. "disabled" means IPv4 will not be used on this connection.

Functions

nm_setting_ip4_config_new ()

NMSetting *
nm_setting_ip4_config_new (void);

Creates a new NMSettingIP4Config object with default values.

Returns

the new empty NMSettingIP4Config object.

[transfer full]

nm_setting_ip4_config_get_dhcp_client_id ()

const char *
nm_setting_ip4_config_get_dhcp_client_id
                               (NMSettingIP4Config *setting);

Returns the value contained in the “dhcp-client-id” property.

Parameters

setting

the NMSettingIP4Config

  

Returns

the configured Client ID to send to the DHCP server when requesting addresses via DHCP.

Types and Values

NM_SETTING_IP4_CONFIG_SETTING_NAME

#define NM_SETTING_IP4_CONFIG_SETTING_NAME "ipv4"

NM_SETTING_IP4_CONFIG_DHCP_CLIENT_ID

#define NM_SETTING_IP4_CONFIG_DHCP_CLIENT_ID     "dhcp-client-id"

NM_SETTING_IP4_CONFIG_METHOD_AUTO

#define NM_SETTING_IP4_CONFIG_METHOD_AUTO       "auto"

IPv4 configuration should be automatically determined via a method appropriate for the hardware interface, ie DHCP or PPP or some other device-specific manner.

NM_SETTING_IP4_CONFIG_METHOD_LINK_LOCAL

#define NM_SETTING_IP4_CONFIG_METHOD_LINK_LOCAL "link-local"

IPv4 configuration should be automatically configured for link-local-only operation.

NM_SETTING_IP4_CONFIG_METHOD_MANUAL

#define NM_SETTING_IP4_CONFIG_METHOD_MANUAL     "manual"

All necessary IPv4 configuration (addresses, prefix, DNS, etc) is specified in the setting's properties.

NM_SETTING_IP4_CONFIG_METHOD_SHARED

#define NM_SETTING_IP4_CONFIG_METHOD_SHARED     "shared"

This connection specifies configuration that allows other computers to connect through it to the default network (usually the Internet). The connection's interface will be assigned a private address, and a DHCP server, caching DNS server, and Network Address Translation (NAT) functionality will be started on this connection's interface to allow other devices to connect through that interface to the default network.

NM_SETTING_IP4_CONFIG_METHOD_DISABLED

#define NM_SETTING_IP4_CONFIG_METHOD_DISABLED   "disabled"

This connection does not use or require IPv4 address and it should be disabled.
