tnet_get_info

#include <net_config.h>

void tnet_get_info (
    REMOTEM* info );    /* Pointer to structure to copy     */
                        /* remote machine information into. */

The tnet_get_info function provides information about the remote machine that has connected to the TCPnet telnet server. The argument info points to a structure into which the function writes the IP address and MAC address of the remote machine.

The tnet_get_info function is in the RL-TCPnet library. The prototype is defined in net_config.h.

note

• You can use the tnet_get_info function to restrict which machines are allowed to perform system changes.
• For PPP or SLIP links, the MAC address is set to 00-00-00-00-00-00.
