Hi, I just noticed, while trying to do a little debugging, that ping6 doesn't seem to have a way to specify "do not fragment" like ping does for IPv4. Obviously the way this is implemented has been changed, since there is no longer a DF-bit in IPv6, but it looks like there is already an IPV6_DONTFRAG setsockopt() available for exactly this purpose. It looks like IPV6_DONTFRAG got added at a later date (from RFC3542), perhaps after ping6 was initially written.
It seems like the correct fix would be to add a cli option to ping6 (perhaps 'D', since it's available and matches the command in ping) to call this setsockopt() and implement a "do not fragment" option. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
