NTP Service - CLI

Could someone please tell me the CLI command to restart the ntpd service on OS X? I am not referring to the GUI method using "Date and Time". I need to remotely restart the ntpd service via command line.

I modified the /etc/ntp.conf and /etc/hostconfig to properly configure our NTP server, but I can't seem to identify the proper syntax to restart the service from the command line. I tried using killall, but it seems to check user processes instead of system processes by default. I have a feeling I'm missing something obvious here...

MacBook, PowerMac, MacPro, iBook, Xserve, Mac OS X (10.4.8)

Hi,

did you 'sudo' ?

sudo killall ntpd

works like a charm on my machine...

sudo ntpd

restarts the thing.

Cheers,
Walter

I had tried that, but I get the error "no matching processes were found". Perhaps I had already killed it and it was no longer running...

I also tried "SystemStarter restart NetworkTime". This appears to work, but if sent via ARD as a "Send UNIX command", it fails.

Anyway, the "killall ntpd" works, so I think I'm just losing my mind... Thanks.
