NTP Server Edition in Configuration

Hi,
I need to have this information that if i do some correction in the existing NTP Server that is my DC (only) so is there any impact on the running application on the rest of the servers in the domain.
request for few suggestions over this.

NTP Server Configuration

Dear All,
I have setup NTP Server with basic steps provided by SUN. In my setup i would be using it for Solaris, WIndows and few OS and devices like Switches and Routers..
I am not sure what additional steps do i need to synch it with servers without using Multicast, i want to use NTP SERVER IP Addresses to synch with clietns.
Here is my current configuration..
===========================================================================
server 0.pool.ntp.org
server 1.pool.ntp.org
server 2.pool.ntp.org
server 3.pool.ntp.org

Please, let me know if you require anymore information..

Hi,
I don't believe that the 7204 has a calendar chip in it. If it doesn't, a reload will clear the clock, setting it to the 1993 date. You should sync the 7204 to an external ntp time source, preferably more than one.
If the 7204 does have a calendar chip, then it will work, but you are still better off using external ntp sources.

Clock setting will be cleared by reload with "ntp server" configuration?

Hi,
I have configured 7204VXR (NPE300) processor with IOS Version 12.1(9) as "ntp server", and the clock settting have not been cleared by system reboot. I remember that the manual clock setting is cleared by reload or power off and on of the device.
Clock setting will not be cleared by reload or power off and on if the device is configured as "ntp server"?

Double check your config. Here's the URL for help: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/fun_c/fcprt3/fcd303.htm#xtocid2592116

Xntpd on Solaris 10 gets synchronised with a higher stratum NTP server

The Solaris 10 machine has the following configuration in etc/inet/ntp.conf
server 10.24.179.33 prefer
server 127.127.1.0
fudge 127.127.1.0 stratum 8
The Linux Fedora Core 4 test machine(10.24.179.33 ) configured as NTP server running ntpd V4 has the following configuration
server 127.127.1.0
fudge 127.127.1.0 stratum 10
The solaris 10 xntpd get synchronised to Linux NTP server even though it is at a higher stratum level.

==============================================================================

LOCAL(0) LOCAL(0) 8 l 17 64 77 0.00 0.000 385.01
The expectation was the solaris machine should not consider the server at a higher stratum level(11) for synchronistation. It should have got synchronised to the Local clock which is at stratum level 8.

I now tried waiting for an hour, but the xntpd id still synchronised to the higher stratum clock from the NTP server 10.24.179.33. Please verify the logs below.
Does the prefer keyword in line "server 10.24.179.33 prefer" has anything to do with this behaviour ?
What does the RFC1305 say on process of selecting a synchronisation source ?
My understanding was that xntpd should not be synchornising with a higher stratum clock from the NTP server (which is at stratum 11) when it already has as another server(here the local clock) which is at a lower stratum (we have simulated this by fudging the local clock to stratum 8).
Please correct me on this.
You have mentioned that "Stratum number is not absolute for choosing a clock. A higher stratum may be preferred in some situations."
Could you explain me more on these situations and I also want to know the rules used by xntpd to choose a clock?
Or you could provide any links where I can read more on this aspect.

Connecting to an NTP server

Good Afternoon.
I'm having a big problem connecting to an NTP server like www.worldTimeServer.com. I want to create a java application that can load time from such servers then display it in my time text field. I do not know how to start.
Can somebody teach me how to do it or give me a link that provides how-tos to do this.

There is a package provided by http://jakarta.apache.org/commons/net/
that have classes for ntp. I myself is new to this (very old) protocol but I'm
building an application that is needing this service so if
you find it helpful let me know.

ASA5500 using Windows 7 computer as NTP server

I have an ASA5510 connected to a computer running Windows 7 (the NTP Server) on its "inside" interface.
Using the ASDM, I have configured the ASA5510 to use the Windows 7 as its NTP server (my architecture forces me to use a local machine as an NTP server):
     -IP address: 192.0.99.1 (the ASA5510 has an IP address of 192.0.99.40)
     -Interface: inside
     -Key number: None
     -Enable NTP authentication: no.
I have other Windows computers on the "inside" interface using the NTP Server, so NTP traffic is relayed without any problem. But somehow, the ASA5510 is not able to synchronize with the NTP Server.
I see the following log entry:
     -Source IP: 192.0.99.1
     -Source Port: 123
     -Destination IP: 192.0.99.40
     -Destination port: 65535
     -Description: Teardown UDP connection 3905 for inside: 192.0.99.1/123 to identity: 192.0.99.40/65535 duration 0:02:01 bytes 96
so it seems like the ASA5510 sends a request to the NTP Server, but I am not sure whether the reply doesn't get processed correctly, or the connection stays open too long (my UDP connection timeout is the default, 2 minutes).
I had trouble getting SonicWALL NSA2400s to use Windows 7 devices as NTP servers. I had to get a firmware version where there was no MD5 authentication (which I think is OK in this case), and change a setting in the Windows registry (HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/W32Time/Config/AnnounceFlags: from 0xa to 0x5)
any insight is welcome.

"Local" failover for NTP Server on Solaris 10

I have four Solaris 10 Servers, all syncing their time from an external NTP server ntp.example.com.
Is it possible to configure one of the four servers as a local "pseudo" Failover NTP, i.e. acting as a client to ntp.example.com, as long as it is available, and acting as a NTP server to the remaining three servers in case ntp.example.com is not available, so that at least the four local servers remain synced among themselves?

Shouldn't be any problem. For one thing you can always specify multiple servers in the /etc/inet/ntp.conf file and use one of them as 'prefer', i.e.:
server ntp.example.com prefer
server local.mydomain.com
Then again, perhaps it would just be easier if one of your servers syncs against 'ntp.example.com' and the rest of your servers always synchronizes against that one server?

SQL 2014 - current SQL Server edition is not supported by MDS

Hi,
we've installed SQL Server 2014 on a Windows 2008 R2 server with a namde instance for the database service.
We also installed MDS 2014 on a different server and configured it with the MDS database on de before mentioned database server.
The configuration gives no error, but when I go to the MDS site, I receive the error in the title.
We installed CU #3 on both servers, but that didn't fix it.
In related articles a possible solution is using a default database instance, but since we can't work with that, that's not really an option for us.
Thanks in advance
Regards
Tony

Hi,
Do you know what's licensing you are using? Any chances you are using "Enterprise Edition: Core-based Licensing".
We fixed a similar issue in CU4. The symptom is same as "SQL Server edition is not supported by MDS".

Final Cut Server Edit Proxy

Hi,
I need to do remote editing (with FCP7) over small bandwith WAN (1Mbps) therefore I configure Final Cut Server (V1.5.1) Edit Proxy to use a Quicktime H.264 codec with the following parameters:
File Extension: mov
Estimated size: unknown
Audio Encoder
AAC, Stereo (L R), 48.000 kHz
Video Encoder
Format: QT
Width: (100% of source)
Height: (100% of source)
Pixel aspect ratio: Default
Crop: None
Padding: None
Frame rate: (100% of source)
Frame Controls: Automatically selected: Off
Codec Type: H.264
Multi-pass: Off, frame reorder: On
Pixel depth: 24
Spatial quality: 0
Min. Spatial quality: 25
Temporal quality: 50
Min. temporal quality: 25
The workflow is:
The remote editor choose on Final Cut Server the FCP project he has to work on, do a Check Out of the project on his Final cut Pro 7 local station by selecting "use: edit proxy" and "keep media with project". Project and associated footage are then uploaded from the server to the remote FCP7 station with no problem.
When the upload is complete, the editor simply open the project file to start editing on his station. This workflow was working allright till january: when opening the project the FCP7 doesn't reconnect the media with an error message:
"one or more of the updates requested by Final Cut Server could not be applied. (one or more replacement (s) had unexpected track setting.)" and media files are Offline! When trying to reconnect manually by indicating the proper path for the missing files, I have to uncheck "Matched Name and reel only" to select the edit proxy files. It looks like it was still linked with the original media...
Looking at the project file, the paths for the proxy files are the proper ones...

If I change the Edit Proxy setting for ProRes 422 (Proxy) on Final Cut Server edit proxy setting then the reconnection is working OK. I cannot use this workaround as the files are then far too big to be tranferred over a 1Mbps WAN.
The setup with the Quicktime H.264 edit proxy was working fine after, it seems, the installation of Pro applications update 2009-01 issued end of october 2009, but since january 2010 it does not work anymore.
Final Cut Server is version 1.5.1 with Mac Os X server is 10.5.8
Editing station are running Final Cut Pro 7.0.1 and Mac Os X 10.5.8
What could be wrong ? Does anybody encountered this type of problem?
Any suggestions welcomed!
Thanks.

I'm dealing with this issue right now (FCSv 1.5.1 latest pro app updates, 10.6.2, FCP7). I was under the impression that you could make edit proxies that were 25% resolution (as opposed to just using an efficient codec), but Final Cut Pro is having a rough time getting it right. I too am only getting success with ProRes-Proxy, audio passthrough, and 100% res/everything else. I tried using Apple Intermediate Codec with default "100%" settings and audio passthrough but had no luck. It's way heavier than ProRes Proxy anyways.
The only suggestion I can make is try your h264 solution with audio passthrough (or Linear PCM) instead of AAC. If that makes a difference we're on to something. Some people started having this issue after an iTunes update, so maybe AAC is the source of the problem.
The edit proxy workflow really needs tweaking from Apple to cater to internet-based solutions rather than fiber/SAN environments where bandwidth is a non-issue.
I'll report back later after some more testing.

NTP Server IP Address ?

Hi,
I have configured a Cisco 6509 core switch as a NTP master and allowed all my access switches to get their time synchronised with the core switch. Now, I want to configure the core switch to get itself synchronised with other public NTP server which would be reliable and genuine as our organisation is serving for healthcare. One of my friend has told me to use these IPs 128.249.1.1 or 128.2.136.71 as a NTP Server in the core switch. Should I use them?
Is Cisco recommends any Public IP for NTP Server synchronisation? Please suggest.
Thanks & Regards,
Anil K.

Disclaimer: I have no affiliation with Cisco in any way except where I work, we use some Cisco products (sw/hw). So take it however you will.
Personally, I would rather adopt the following approach suggested at http://www.pool.ntp.org/en/use.html, than hardcoding a couple of public NTP servers in a remote region:
"As pool.ntp.org will assign you timeservers from all over the world, time quality will not be ideal. You get a bit better result if you use the continental zones (For example europe, north-america, oceania or asia.pool.ntp.org), and even better time if you use the country zone (like ch.pool.ntp.org in Switzerland) - for all these zones, you can again use the 0, 1 or 2 prefixes, like 0.ch.pool.ntp.org. Note, however, that the country zone might not exist for your country, or might contain only one or two timeservers. If you know timeservers that are really close to you (measured by network distance, with traceroute or ping), time probably will be even better. "
Of course, if time sync is REALLY that important, one might consider buying/installing commercial GPS-based NTP appliances. That's not what you're looking for, obviously.

If external NTP device is down will have any impact in the cluster setup?You should configure the cluster nodes as peers as well as getting the time from the external NTP server.
If the external NTP server fails, then time will drift, but at least the cluster nodes keep themselves in sync to have a consistent view.

CER 7.1.1 install - no NTP server option

Trying to install CER 7.1.1. When I get to the Network Time Protocol Client Configuration window it prompts me to put in an NTP server IP address. The install never prompts me to configure an NTP server or not. The install doc says that I should get prompted to choose NTP or not, just like a CUCM install. Did I do something wrong? I tried it several times and get the same thing. I have a Not For Resale disc and this is in a lab. Is there something special about that disc? I don't want to use NTP but I configured a Win2K3 server to be the NTP server, it's reachable but the install can never connect to it. Needless to say, I can't finish the install. Below is what I get.
Network Time Protocol Client Configuration
NTP Server 1 ---------
NTP Server 2 ---------
NTP Server 3 ----------
NTP Server 4 ----------
NTP Server 5 ----------
There is no option to choose No NTP. You either have to put in an NTP server or you can't move on with the installation.

Thanks for the replies. I was using an installation guide, below, that shows the option to choose NTP or not on step 18. Is the document wrong then? In any case, I tried the hacks for Windows, no go. I tried Linux NTP {Ubuntu], no go. Otherwise, I just have a voice gateway and a 3524 that doesn't do NTP server. Any suggestions on getting Linux to work with CER NTP? Thanks.
Step 18 On the Network Time Protocol Client Configuration page, you are asked if you want to set up external Network Time Protocol (NTP) servers.
Note Cisco strongly recommends that you use external NTP servers to ensure that the system time is kept accurate.
If you click Yes, the system displays a second Network Time Protocol Client Configuration page. In the fields provided, enter the IP address or hostname of the external NTP servers, then click OK. The Database Access Security Configuration page displays. Skip to Step 19.
If you click No, the Hardware Clock Configuration page appears. Enter the following information:
• Year [yyyy]
• Month [mm]
• Day [dd]
• Hour [hh]
• Minute [mm]
• Second [ss]
When you have finished entering this information, click OK. The Database Access Security Configuration page appears.

NTP server - can't fix it

Hello,
I have two 10.6.4 server machines wich I use as NTP server for my clients (both referes to time.europe.apple.com and have flagged NTP under general settings to enable NTP).
One of them works properly: if on a client i use his FQDN or IP they took istantly the right hour.. the other one is like unseen from clients.
both of them have the following files configurations:
/private/etc/ntp.conf
server time.euro.apple.com
/private/etc/ntp-restrict.conf
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
#localhost is unrestricted
restrict 127.0.0.1
restrict -6 ::1
includefile /private/etc/ntp.conf
I can figure out why one of them works and the other one not..
Both of them have firewall service off.

Maybe if you tried to restore your computer back to a month ago or sometime before you had this problem?
