Hi: A problem is encounted while porting "queso". (ports/8305) ftp://freebsd.ntu.edu.tw/freebsd/woju/ports/queso.tgz How to determin local ip without establishing a connection? My ports now use the method like /usr/share/examples/find_interface/. After reporting this port to savage(queso's author), he said "queso determines remote OS without establishing connections". In file queso-980922/tcpip.c -- getlocalip (unsigned long dest) { static struct in_addr ina; #ifdef LINUX /*---------------------------------------------- LINUX --*/ int i; for (i = 0; i < numroutes; i++) { if ((dest & routes[i].naddr) == (unsigned long) routes[i].addr.s_addr) { return (routes[i].iface->addr); } } #else /* !LINUX ---------------------------------------------- OTHER --*/ My ports -- #elif defined(__FreeBSD__) /*------------------------------- FreeBSD --*/ /* Ref: /usr/share/examples/find_interface/ */ If anybody know some other way to determine output IP, please let me know. Thanks. - woju ( FreeBSD Chinese BIG5 Document/FAQ http://bsd.wj.ml.org ) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
