Hey Doug-- I'm trying to reproduce this problem but without success. I did an install of 6.2-RC1/i386 from CD into a Parallels VM, then manually updated /etc/rc.d/auto_linklocal to version 1.1.2.3.2.1 (same as 1.4 you tested with). I'm running a GENERIC kernel with ipv6_enable=3D"NO" set i= n /etc/rc.conf. I set sshd_enable=3D"YES" and sendmail_enable=3D"YES" and they both seem to be behaving normally. vm2# ifconfig ed0: flags=3D8843 mtu 1500 inet WW.XX.YY.ZZ netmask 0xffffff00 broadcast WW.XX.YY.255 ether 00:5d:54:14:12:1a media: Ethernet autoselect (10baseT/UTP) lo0: flags=3D8049 mtu 16384 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 I also remember lightly testing this change before it was committed, so I'm kind of puzzled by the problems you saw. Do you have any other information that you think might be useful? Thanks!
