 how to manage ARP entries via ioctl(2) ? how do i manage ARP entries via ioctl(2) in OpenBSD ? i have the folowing code that works in linux : ------start------------ __int32_t func(__int32_t ip){ #if defined(__OpenBSD__)|| defined(__NetBSD__) sockfd= socket(AF_INET,SOCK_DGRAM,0); #endif #if defined(__linux__) sockfd = socket(PF_INET,SOCK_DGRAM,0); #endif <... check return value ...> addr = (struct sockaddr_in*)&arp_req.arp_pa; bzero((void*)addr,sizeof(struct sockaddr_in)); #if defined (__OpenBSD__)||defined(__NetBSD__) addr->sin_family = AF_INET; #endif #if defined (__linux__) addr->sin_family = PF_INET; #endif addr->sin_addr.s_addr = ip; ret_val = ioctl(sockfd, SIOCDARP,&arp_req); <... check return value ...> close(sockdf); return 0; } ----end-------------- however i cannot even compile it under OpenBSD . the message i'm getting is : SIOCDARP : undaclared . i've looked at OpenBSD's arp.c and have not found and call ioctl(2) . can anybody explain me how ARP entries are managed in OpenBSD's arp.c ?      |
