so I am running NTP on my gentoo box right. Installed it with emerge, and it is almost always like 10 mins or so ahead. Why, I do not know, but it is.

ntp is in my start up script, so its running when I boot up, but it just always keeps it ten mins ahead, what should I do to fix this?

o ya, I am using the military servers tic and toc for my servers. Somehow I was getting my time from the U here but I don't know how that happened since I didn't add it to my list of servers.

Take a look in the file /etc/ntp.conf

Also you can run the command:

ntpq

in that prompt, type peers and you will get the info about what you are synced to...

See if you are running ntpd at startup ... do:

ls -al /etc/runlevels/default/ | grep ntp

It should say

lrwxrwxrwx 1 root root 16 Mar 27 2004 ntpd -> /etc/init.d/ntpd

its still screwed up. Right now its reading just shy of 20 mins ahead.

This is the output of ntpq> peers



So I am connected to tick and tock. But for what ever reason its 20 mins off.



That seems right to. I don't get it.

Actually, you are not connected ... when connected, it looks like this:



So it looks like you may have a firewall issue...

I haven't even touched my firewall since I set up my system, so its got to be how ever gentoo has it set by default.

So what port do I need to open and what do I need to do to open it?

In looking at my /var/lib/iptables/rules-save, I don't have anything in there about ntp either...

so I'm not sure why you aren't working

I am going to include several items from my setup:
-------------------------------------------
Here are all the uncommented lines in /etc/ntp.conf

(the last line is not super important ... and restricts who can sync with this server {that is, my internal netowrk only}, it shouldn't effect the client)
---------------------------------------
here are the uncommented lines in /etc/conf.d/ntp-client

(I use another time server on my network for the initial time sync {192.168.0.2}, you can probably leave this remarked out, OR set it to NTPCLIENT_OPTS="-b pool.ntp.org"
---------------------------------------
Here are all the uncommented lines for /etc/conf.d/ntpd

---------------------------------------
I would copy the current files to .bak, then update each with what I gave you and see if it starts sync'ing ... (after changing the files do /etc/init.d/ntp-client restart and /etc/init.d/ntpd restart)

If you still can't sync, I would recommend that you turn off your firewall (/etc/init.d/iptables stop), restart the ntp-client and ntpd services, wait 30 minutes and see if they sync ... if they do, it is an IPTABLES problem ... if not, something else is the issue (maybe a school proxy/firewall).

so some how, I have no idea, my /etc/ntp.conf file got changed. It used to look like yours (more or less) with tick and toc and the servers, now it looks like this.



And I get this from a ntpq> peers


So it looks like I am actually connected to the UofM's times servers, but my clock is still off by over 20 mins.

So I don't know how that happened. Is it possible a env-update did it?

I am going to replace the stuff with tic and toc and see what happens.

So it would apear that I am connected, now how do I get it to actually change my clock since its still 20 mins ahead?

There is a maximum time, above which no adjustment is made. Set your time a little closer to the real time and NTP will then adjust it.

set it like this:

date MMDDhhmmyyyy

so 10/19/2004 at 20:51 would be:

date 101920512004

after you get closer, it should maintain the time.
-------------
I have never had env-update change my ntp.conf file ... but it might make changes based on your network subnet. So if you are on the same subnet as the time server at UM and it is registered at pool.ntp.org, etc-update might have set the servers in your ntp.conf. I am on a 192.168.x.x subnet, so it might have left mine alone.

It still shows that I am connected to the nave time servers, but my clock is still off by like 5 mins. Any other god ideas?

something is very odd with the install ... I would try to unmerge ntp, delete the ntpd.conf (save your server IPs) file, and then re-emerge it and adjust your /etc/ntp.conf file.

emerge unmerge ntp
del /etc/ntp.conf
emerge ntp

After running for about an hour, it should adjust your time.

Did your NTP ever adjust the clock?

Ok, so my NTP is still tweeking out.

It still doesn't adjust my clock.

This is my /etc/ntp.conf file:


Which looks nothing like it did the last time I saw it. The last time I saw it, it was chock full of comments and the servers were set to tick and tock.

So now with that ntp.conf file this is what I get from peers.


So I have no idea why its doing that. There might be something wierd with an ntp time server on campus, but I don't know who I would even go ask about that. Maybe I am just doomed to have it not work.

get rid of all the restrict stuff for now, and just put in these lines:



Then, do:

chmod 444 /etc/ntp.conf

Then see what happens...(you will have to do chmod 644 /etc/ntp.conf later as root to change the file). That should keep it from changing.

This is just totally jacked up.

Right, so my windows system crashed so I had to fix that, so now I am back to linux and I want to have the right time.

So, I edited it and changed the permision right, even with the permision at 444 it still changes the file when I reboot.

So I change it to look like the one above right, and when I reboot it looks like this.



and a ntpq> peers looks like this


So some how either it just so happens that the university runs its servers on the default connection, or maybe the U's time servers are high jacking mine, either way, its almost 40 mins off now. So I don't know what the hell to do.
