int main(int argc, char \*argv\[\])\
 {\
\
         YIPUnion ip;\
\
         YConnection \*con = YOpenConnection(\
\
                 "/usr/sbin/starty",\
\
                 "127.0.0.1:9433"\

\
         ip.charaddr\[0\] = 207;\
\
         ip.charaddr\[1\] = 200;\
\
         ip.charaddr\[2\] = 89;\
\
         ip.charaddr\[3\] = 225;\
\
         if(YAddHost(con, &ip))\
