I have not seen these issues, can you give a specific example that fails? A netstat -rn on a v4 only kernel simple reports the v4 table, and iirc a netstat -rn6 returns a "Protocol not supported error" as should all other things. > World built WITHOUT_INET6 has no such rough edges. I find that actually causes me more issues, as then my netstat -rn6 returns a hard error due to: case '6': #ifdef INET6 af = AF_INET6; #else errx(1, "IPv6 support is not compiled in"); #endif -- Rod Grimes rgri...@freebsd.org _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
