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.

Referenced by AsixInit(), cs8900Init(), CSNicInit(), NicInit(), NutNetLoadConfig(), and NutNetSaveConfig().

char _CONFNET::cd_name[9]

Magic cookie.

Contains the device name of the network interface.

Examples:

editconf/editconf.c.

Referenced by AsixInit(), main(), NutNetIfSetup(), and NutNetLoadConfig().

uint8_t _CONFNET::cdn_mac[6]

Ethernet MAC address.

Unique Ethernet address of the network interface.

Examples:

editconf/editconf.c.

Referenced by AsixInit(), cs8900Init(), CSNicInit(), DiscoveryResponder(), main(), NicInit(), NutDhcpIfConfig(), NutDiscoveryAnnTele(), NutDiscoveryAppConf(), NutNetIfSetup(), and NutNetLoadConfig().

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.

Examples:

ftpd/ftpserv.c, httpd/httpserv.c, httpd_simple/httpd_simple.c, httpd_upnp/httpserv.c, inetq/inetq.c, logtime/logtime.c, pingnet/pingnet.c, and tcps/tcps.c.

Referenced by DiscoveryResponder(), main(), NutDhcpClient(), NutDhcpIfConfig(), NutDiscoveryAnnTele(), NutDiscoveryAppConf(), NutNetIfSetup(), and syslog_header().

uint32_t _CONFNET::cdn_ip_mask

IP netmask.

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

Examples:

editconf/editconf.c, ftpd/ftpserv.c, httpd/httpserv.c, pingnet/pingnet.c, and tcps/tcps.c.

Referenced by DiscoveryResponder(), main(), NutDhcpClient(), NutDhcpIfConfig(), NutDiscoveryAnnTele(), NutDiscoveryAppConf(), NutNetIfSetup(), and NutNetLoadConfig().

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.

Examples:

editconf/editconf.c, and logtime/logtime.c.

Referenced by main(), NutDhcpIfConfig(), NutDiscoveryAnnTele(), NutDiscoveryAppConf(), NutNetIfSetup(), and NutNetLoadConfig().

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.

Examples:

editconf/editconf.c, and tcps/tcps.c.

Referenced by main(), NutDhcpIfConfig(), NutDiscoveryAnnTele(), NutDiscoveryAppConf(), NutNetLoadConfig(), and syslog_header().
