Can someone help me to setup ntpd? Do i need a static ip for this one? I've browsed the ntp.org, but it's just too complicated for me. Thanks.

Great link! I hadn't seen it before. ntp.org is definitely over-complicated -- they're trying to "tell you how to build a watch, when all you asked for was the correct time". ( sorry, couldn't resist.)

Some notes: (from memory... mine)

The norm for ntp is to check the time every 1024 sec. (17.066... min.) after stabilizing. This is acceptable; however, it is considered abusive to have a non-server check this often, 1 to 3 times per day being recommended (if I remember correctly). The rule of thumb is, as soon as you have 3 boxen needing time sync, you should set up your own server & sync your LAN to that.

Read the
Rules of Engagement! (And follow them.)

If you use the server list, Stratum Two Time Servers (please don't touch the ones in Stratum 1), please pay attention to the "AccessPolicy:" & "Notify?" fields.

Consider the pools: NTP Pool Time Servers; as well as your own ISP, who really ought to be supplying you with a time server.

I used to know some tricks to track down my ISP's server, but it's been so long ago I've forgotten, sorry.

The "Resources" list from the NTP Cookbook above:

• man ntpd
• man ntp.conf
• /usr/share/doc/ntp/ (complete HTML documentation)
• e2epi.internet2.edu/owamp/details.html#NTP
• http://twiki.ntp.org/bin/view/Suppor...siteNTPServers

FWIW, my 500th post.

Most distro's should do the basic setup for you. i.e. setup the drift file etc and then you need only setup the reference servers in /etc/ntp.conf. The best thing to do is to use the pool.ntp.org servers and enter 3 lines in your /etc/ntp.conf file like this;

server pool.ntp.org
server pool.ntp.org
server pool.ntp.org

This will allow you to contact different servers in the pool and the software will then select the one that has the best time and is closest to you. Setting it up like this also will prevent you latching on to a server that is bad. I run a server for the pool and use 6 servers in my list

Please read NTP Pool Time Servers it is at odds with the /etc/ntp.conf details in the the post above.
