ntpd and ntpdate

Hi,

If I look at the following on my 10.1 machine:
/System/Library/StartupItems/NetworkTime/NetworkTime

There are the following startup commands for ntp services:

ntpdate -bvs
ntpd -f /var/run/ntp.drift -p /var/run/ntpd.pid

Please can someone confirm that these commands get their ntp server information from netinfo. If they do then are these modified versions of standard unix commands? How would I know these commands were referencing netinfo without a calculated guess? I notice there are no man pages for these commands!

thanks,
amxd.
 
I dont have my machine in front of me but in the Date/Time syspref,
you can specify an NTP host (default is a list of Apple time servers).

I altered it to one of our corporate servers and my Ti sync's fine.
 
Any advise for firewall configuration for NTP. My router has a preset that doesn't appear to be a problem, as the OS X firewall appears to be receiving the response from the server, and blocking it. As far as I can tell, UDP port 123 is used for outgoing and incoming data, but the data getting blocked in coming in on a range of numbers (not at my machine but I want to say 65???).

Anybody know exactly what ports are used. I like to minimize the number I have open.
