Hi, What i did to print the prefixes on a perticular ifnet structure are as follows. I entered the prefixes a) fec0:11:0:0 in the configuration file for the interface wb0. I wrote a printf in the ip6_input function. the printf is as follows printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[0]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[1]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[2]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[3]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[4]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[5]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[6]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[7]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[8]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[9]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[10]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[11]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[12]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[13]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[14]); printf(" %x \t", ifp->if_prefixhead.tqe_next->prefix.s6_addr8[15]); Where ifp is declared as , struct ifnet *ifp; Then i bulit a new kernel, compiled it & loaded it as my working kernel. Each time any ip6 input used to come the above printf used to get executed. I gave the following command on the prompt pin6 -I wb0 fe80::280:48ff:feb6:57ac I got the following output for the prefix fec0:11:0:0 in the configuration file. Output 0 0 0 0 0 0 fe c0 00 11 00 00 00 00 00 My expectation was that the prefix fec0 would be the first 2bytes but they are located after 6bytes. Could u tell me what is wrong & why am i getting this print out. Waiting for ur reply. regards ravi prasad JINMEI Tatuya / <jinmei@isl.rdc.toshiba.co.jp> wrote: > > >>>>> On Wed, 06 Jun 2001 08:43:51 -0400, > >>>>> raviprasad20@netscape.net said: > > > As per your advice i left the prefix command & gave prefixes in the configuration file /etc/defaults/rc.conf itself.
