Jan 8, 2010I cant get ntpd to synchronize with the ntp servers. I have a CentOS 5.3 32 bit Virtual Machine. I'm in USA on Pacific Standard Time. Here's all configuration and other important information for troubleshooting. Is there anything wrong with my config? btw, I used wireshark to look at the UDP packets - I dont get any responses from any of the servers back. I only see requests going out from my server, but no response. Is this a firewall Issue? If it is, then do I need to just enable UDP port 123 on the firewall?

Fedora Security :: NTPD Error Report At Startup Of Machine
Jan 25, 2011I've been trying to make sense out of this error report. I get it every once in a while on startup of my machine.
Code:
Summary:
SELinux is preventing /usr/sbin/ntpd access to a leaked netlink_route_socket
file descriptor.
Detailed Description:
[ntpd has a permissive type (ntpd_t). This access was not denied.]
SELinux denied access requested by the ntpd command. It looks like this is either a leaked descriptor or ntpd output was redirected to a file it is not allowed to access. Leaks usually can be ignored since SELinux is just closing the leak and reporting the error. The application does not use the descriptor, so it will run properly. If this is a redirection, you will not get output in the netlink_route_socket. You should generate a bugzilla on selinux-policy, and it will get routed to the appropriate package. You can safely ignore this avc.
Allowing Access:
You can generate a local policy module to allow this access - see FAQ [URL]

View 7 Replies View RelatedCentOS 5 :: How To Set Up NTPD Properly
Dec 16, 2009I have a Windows 2003 server that runs a Win32 time server which synchronizes with off site time sources. I have a CentOS 5.4 server which I just configured and installed NTP on. For some reason, I keep getting time discrepancies even after the server is (apparently) synching with my local NTP server on the Windows box.
Hwclock is set to UTC true/etc/localtime is properly symlinked to appropriate /usr/share/zoneinfo fileNTPD is setup as a service which loads on startupNTP.conf is configured to only retrieve from my local Windows 2003 time serverntpq -p seems to verify that the system is indeed synching up properlyThe problem is, whenever I run the 'date' command it is displaying my system time in (presumably) UTC. That is, even though my the CentOS box appears to be synching up to the local time, it's not translating it into my proper time zone. Consequently, the date is always at -6 hours from the actual local time. It was my understanding that the hwclock is fine to remain at UTC as ntpd should be synching with my local Windows 2003 time server periodically and updating it, and the system time should be getting translated to my localtime.
what I do, after rebooting the box the hwclock and system clock display the improper time.Maybe I just have a fundamental misunderstanding of how this is supposed to operate.Update: I'm not sure why, but after I commented out the other servers and added a fudge declaration for my internal server and rebooted, everything is working as it should and the time is correct.I'm still not really sure if it was adding the "fudge <hostname> stratum 2" declaration that corrected things, or commenting out the additional hosts, so I'll leave this open if anyone cares to comment or contribute.

CentOS 5 :: Clock Time Jumps Into The Future (Xen + Ntpd)?
Nov 20, 2009I'm having a problem with the time on one of my servers jumping forward into the future. We run serveral CentOS 5.4 servers running Xen, some up to date and some a little older. The one in question is running 2.6.18-164.el5xen, with xen-libs-3.0.3-94.el5_4.2 and xen-3.0.3-94.el5_4.2. On this server are several Xen virtual machines, also running CentOS 5.4 with kernel 2.6.18-164.el5xen. One in particular has problems with the clock keeping proper time.
We use NTP (ntpd) to sync time to a central server in the company. Our NTP set-up works fine, and we have problems on only a couple of servers out of many. The problem I see is that one one particular Xen virtual machine, the clock will suddenly jump forward into the future, usually by several minutes but once by more than an hour. This has obvious implications for software running on the machine. Software such as Oracle grid control agent will restart itself under the (incorrect) assumption that it has been hung for several minutes with no activity. Oracle database will cope gracefully, but applications that refer to the clock will be confused.
We detect these time jumps because we have Nagios checking the clock on each host against the centralised time server (Nagios's check_ntp plugin). Nagios will suddenly report a clock offset that is miles into the future. Following the time jump, ntpd on the host in question will re-sync the time. Ntpd keeps the time steady, ticking just a few milliseconds per second until real time catches up with the server. i.e. Nagios will report the time as being 10 minutes ahead, then a minute later the host will be 9 minutes ahead, and then a further minute later the host will be 8 minutes ahead of real time. The clock on the host stays running very slow until it eventually is correct.

For ntp, when the server completed the boot process, altough it seems ntpd started, no external server is used for syncronization. The rpc.statd does not start at all and it doesn't appear if I issue a rpcinfo -p
The strange thing is that at this point if I manually start or restart /etc/init.d/ntpd and /etc/init.d/nfslock both services start with no errors. Another strange thing is the timestamp for messages into /var/log/messages. How could it be possible to have a line with a certain timestamp and the following with a timestamp 30 seconds before?

Debian :: Sync Clock - NTPD Not Starting On Boot
Jul 19, 2011I'm trying to sync my clock. I think I would like to do this by the "ntpd" daemon running. I think it should start up on boot, but it doesn't.
I have the following in my /var/log/syslog:
Jul 18 23:44:14 neo ntpd[1780]: ntpd 4.2.6p2@1.2194-o Sun Oct 17 13:45:13 UTC 2010 (1)

Jul 18 23:44:14 neo ntpdate[1194]: step time server 72.26.125.125 offset -0.505108 sec
Other posts say if ntpd and ntpdate run too close together, they cause one to think the other is locking a resource. It works to type "ntpdate pool.ntp.org" to manually update the clock. My Debian version is squeeze (6.0.2)
It works to start the ntpd daemon manually:
... sudo /etc/init.d/ntp start
... Starting NTP server: ntpd.
Ubuntu :: "GRUB _" Appears At Startup & Fails To Boot?
Mar 29, 2010A couple weeks ago I installed Ubuntu Security and Recommended Updates that included an update to Linux Kernel 2.6.31-20. Upon installing these updates I was prompted to restart my computer for the changes to take effect. So I rebooted and encountered a Hyper Transport Sync Flood error each time I tried to boot, preventing me from booting into the OS.The above linked forum thread about the error suggested I manually adjust voltage settings in the BIOS to resolve the issue, so I gave it a try to no avail. Then I decided I would just reset my BIOS settings to the defaults (seeing as I hadn't edited that many settings to begin with). After doing so, I tried booting only to encounter a black screen with "GRUB _" printed on it.
I have encountered this issue before when I initially installed Ubuntu 9.10 on my system, but I'm not sure whether this occurrence is strictly BIOS setting related or if something effected my bootloader. (On a side note, resetting my BIOS settings to defaults seemed to, at least for now, eliminate the Hyper Transport Sync Flood error I was getting...and instead leave me with another problem.)I used this script created by meierfra. to provide info on my current boot setup, the results of which are displayed below.

General :: Synchronize The Time Of VM Server With Ntpd?
Mar 22, 2010I am trying to synchronize the time of my VM server with ntpd. I have the following configuration. And in the /etc/ntp.conf, I have the following line:
restrict default ignore
restrict 127.0.0.1.
server time1.server
server time2.server
Whenever I have this line, the erver is not able to synchronize its time... So far as I understood, this line prevents other servers using this machine as a time server. And the second line says to allow localhost to use as time server. But why do I need to use its own time server when I have specified to use time1.server and time2.server ? ( firewall for tcp and udp ports 123 is open)
However, when I replace the first line of the configuration with the following line, it works. restrict default kod nomodify notrap noquery But with this, i am allowing other servers to use this server a ntp (which I wouldn't like to). Why this machine tries to use ntp server of its own (to snyc time) and why it is not working though i have the entry "restrict 127.0.0.1" ??

I am running Debian Lenny 64b, and every packages are totally updated. I have 25 identical servers. And there is just one giving me this problem. From what I see, it is not a connection/FW issue since ntpdate get replies from the ntp server (ntp.skynet.be is my isp's stratum 2 ntp server).
CentOS 5 :: Ddclient Fails To Start At Boot / What To Do?

I can manually run it from the prompt with /etc/rc.d/init.d/ddclient start

When I reboot though, during the startup, I get the following:

I am very new to Linux, so I am not sure what or where I should be looking to solve the problem. It seems to me that it must be looking in the wrong spot for ddclient, but I don't know what to check or change to point it at the right place.
