I want my local ntp server up and running, so I put in /etc/rc.conf:
xntpd_enable="YES" but waht are the right rules for ipfilter? Someting
# Allow out ntp traffic
pass out quick on rl0 proto tcp from any to any port = 123 flags S keep
pass out quick on rl0 proto udp from any to any port = 123 keep state
Or do I have to open some ports incoming as well?
[ I think I need a good book about ipfilter ;-) ]
I mentioned tcp/udp because I read in /etc/services that ntp uses both.
Does keep state mean that automagically all incoming traffic will be OK
