Ok - My machine is on a LAN which has their own dedicated NTP server. How can I make my machine sync with our local NTP server? Is their a command? I don't recall but I beleive I have a NTP service running on my Debian machine - I just forgot how to command it to sync. I did google this and came up confused.
Can anyone tell me if I have the correct services configured to sync with a local NTP server and how to do so?
Not at my Debian box, but I think I installed ntp and then edited /etc/ntp.conf to contain a server on my network. Then I just restarted the ntp service. If you only need to have a client, you can use ntpdate and run it once from a cronjob.
cwilliams:/home/cwilliams# apt-cache search ntp-server

cwilliams:/home/cwilliams# apt-get install ntp-server

I have edited the ntp.conf file with my local NTP servers and saved the file. Now what? How do I force a sync w/o rebooting.
So I have to run an NTP server utility on my machine just to sync to an NTP server? I don't want my machine to be an NTP server if that makes sence.
It doesn't have to be a server in strict terms but could be. A quick explanation will help you understand. The server software starts by getting time from the remote server every 64 seconds. It then calculates the natural error of your own system clock and places this info in the drift file. As the drift becomes more consistent it reduces the number of requests made on the remote server and finally settles on a request rate of 1024 seconds because the software can compensate for the error of the system clock. The problem with an app like ntpdate is that it fires a wholes series of requests at the remote server and admins that run these can get a bit techy about this. I run a server as part of the ntp.pool.org and it really p....ses me off.
