Configuration: 5.3-STABLE. I have 2 DHCP interfaces (a bit strange,
but it does not matter). Right after dhclient i have the next situation:
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=1b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING>
inet 192.168.0.114 netmask 0xffffff00 broadcast 192.168.0.255
ether 00:e0:81:61:1b:fd
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000
rue0: flags=108843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
ether 00:10:60:e9:33:2c
media: Ethernet autoselect (none)
status: no carrier
Note that rue0 has address 0.0.0.0
Now i'd like to sync time on the box using ntpd -q, and i got

I've made some research and found the source of problem. It is in
ntp_io.c See lines 522-526. They blacklist addresses of local
interfaces.
But hack_restrict has this code fo find restrictions list
entry(ntp_restrict:327):
if (addr == 0) {
rlprev = 0;
rl = restrictlist;
} else {
it finds first entry of list (0.0.0.0/0.0.0.0) and marks it as
blacklisted. Theis means we restrict all packets. I think the fix will
be
if ((addr == 0) && (mask == 0)) {
Any comments from gurus?
PS Sorry for a bit long message, i just want to make the things clear.
