Thanks.
You sure it wasn't being turned on in rc.conf instead? Anything else
would mean that someone was messing with rc.network or
/etc/default/rc.conf, which really should be left alone.

I am using 4.8
i think it was a problem with rc.network.
even it says
log_in_vain=0 # =1 to log connects to ports w/o listeners.
in /etc/defaults/rc.conf.
rc.network is
code 1
network_pass4() {
echo -n 'Additional TCP options:'
case ${log_in_vain} in
[Nn][Oo] | '')
;;
*)
echo -n ' log_in_vain=YES'
sysctl -w net.inet.tcp.log_in_vain=1 /dev/null
sysctl -w net.inet.udp.log_in_vain=1 /dev/null
;;
esac
echo '.'
network_pass4_done=YES
}
/code
this is fixed in stable as far as i see.
code 2
network_pass4() {
echo -n 'Additional TCP options:'
case ${log_in_vain} in
[Nn][Oo] | '')
log_in_vain=0
;;
[Yy][Ee][Ss])
log_in_vain=1
;;
[0-9]*)
;;
*)
echo invalid log_in_vain setting: ${log_in_vain}
log_in_vain=0
;;
esac
if [ ${log_in_vain} -ne 0 ]; then
echo -n log_in_vain=${log_in_vain}
sysctl net.inet.tcp.log_in_vain=${log_in_vain} /dev/null
sysctl net.inet.udp.log_in_vain=${log_in_vain} /dev/null
fi
echo '.'
network_pass4_done=YES
}
/code
in code 1 log_in_vain=* results it to be log_in_vain=1
if it is not NO
in code 2 log_in_vain=0 works as predicted ...
solution :
1 - put log_in_vain=NO into /etc/rc.conf
2 - modify your rc.network ---
i did the second for my box and gone to single user
and back to multiuser and there was no problem ..
Ps : code 2 is from src/etc/rc.network and 1 is 4.8's version
