Field Documentation

uint8_t CONFNET::cd_size

Size of this structure.

Used by Nut/Net to verify, that the structure contents is valid after reading it from non-volatile memory.

Definition at line 114 of file confnet.h.

char CONFNET::cd_name[9]

Magic cookie.

Contains the device name of the network interface.

Definition at line 120 of file confnet.h.

uint8_t CONFNET::cdn_mac[6]

Ethernet MAC address.

Unique Ethernet address of the network interface.

Definition at line 126 of file confnet.h.

uint32_t CONFNET::cdn_ip_addr

Last used IP address.

Each time Nut/Net receives an IP address during boot, it will store the address in here.

If no fixed IP address has been configured (cdn_cip_addr contains 0.0.0.0) and if no DHCP server is available, then Nut/Net will use this one, if it is not 0.0.0.0.

Definition at line 137 of file confnet.h.

uint32_t CONFNET::cdn_ip_mask

IP netmask.

The netmask is used to determine which machines are available in the local network.

Definition at line 144 of file confnet.h.

uint32_t CONFNET::cdn_gateway

Default route.

Nut/Net will redirect IP packets to this node, if the target IP is not located in the local network.

Definition at line 151 of file confnet.h.

uint32_t CONFNET::cdn_cip_addr

Configured IP address.

If this address is set to 0.0.0.0, Nut/Net will try to obtain one from the DHCP server.

Definition at line 158 of file confnet.h.
