Yes. I think most of my work was with connected sockets. I poked around a bit and haven't figured out how to use it, but it feels like it should work. Other people have encountered this problem. This is clearly the answer. I just don't understand the details yet. Do you a good example? Google found one. My best guess so far is that IP_PKTINFO is a socket option and there is an assumption in recvmsg/sendmsg that there are no other options that would use "control" info. > I checked and we're not going to have BSD port issues. I can't find either IP_PKTINFO or in_pktinfo in /usr/include/ on FreeBSD. Is this going to be fatal? OpenBSD has IN6P_PKTINFO and in6_pktinfo. I don't see anything for IPv4. Looks NetBSD is OK. Again, that's just with grep. I haven't verified that anything works. -- These are my opinions. I hate spam. _______________________________________________ devel mailing list devel@ntpsec.org http://lists.ntpsec.org/mailman/listinfo/devel
