Ntp server connection

Hello,
have a problem connecting to the ntp server please see below:

clock offset is 0.0000 msec, root delay is 0.00 msec
root dispersion is 0.00 msec, peer dispersion is 0.00 msec
any reasons as this is the first time I am trying to synch to an NTP server.
on the wan inbound I have permitted the destination udp 123 port through the access-list

Do you have any ACL input in Gateway...disable one moment for test...it could be a problem from your ISP or ISP filter/Firewall input/output?? Could you try with another NTP server...

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.

Help with connecting to NIST NTP server on port 123

I can get NIST time in Daytime format using the rt_nist_date_time.llb example posted on ni.com, but I cannot connect to NIST NTP format time data using port 123. I freely admit to being over my head with this stuff, and have spent much of this Thanksgiving holiday reading about UDP and TCP.
The attached vi summarizes what I've tried so far. The UDP case is what I thought would work, but I can't come up with a network address that the UDP-open vi likes. Can anyone out there help this n00b tell the time?
The attached file is supposed to be in 8.0 format, although I'm working in 9.0
Here is a link discussing the time formats: http://tf.nist.gov/service/its.htm

THANK YOU!!! I don't think I ever would have come up with connecting the web address to a Read or Write UDP rather than the Open UDP block. Not to mention starting by opening port zero.
Unlike TCP, UDP is a connectionless protocol. Here's a quick explanation in different words.
A udp packet travels from a [sourceIP, sourcePort] to a [DestinationIP, destinationPort].
UDP open basically reserves a local port used for sending (soucePort) and receiving (incoming packet with that same destinationPort). Since some local ports are always in use, you would generate an error if you would accidentally pick a used port. Picking zero is useful for requests (as in this case!), because the OS will pick an unused ephemeral port. The actual source port number does not matter because the NTP server will just send the reply packet back to whatever port it came from. (If you would write your own NTP server in LabVIEW, you would of course need to set the local port to 123, and would get a conflict if another NTP server is already running on your rig). Writing an NTP server in LabVIEW would be a trivial modification to the current code, try it! . Simply listen for packets on port 123, form a response packet based on the timestamp, and send it to whatever IP/Port it came from (that info is available from udp read) and then go back to listen for new requests.).
UDP write sends a packet to the server using the above opened local port as source port. You can use the same connectionID to write to several other servers and ports, because UDP is connectionless. (TCP is connection based, so a TCP connection involves a defined source/destination pair)
UDP read listens for incoming packets from all over the world at that same local port. It is very unlikely, but theoretically possible that other UDP packets will arrive at that same port, so you could even filter to make sure to read incoming packets until they match the port and IP of the original request. The current code is somewhat vulnerable to a DOS (denial of service) attack for example as follows: Imagine the guy in the next cubicle had means of sniffing your network traffic. He could write a small program that looks for your NTP requests and then immediately starts flooding your IP with meaningless UDP packets to the sourcePort you just used. The current program only reads one packet and thus will never see the return packet from the NTP server.
UDP close frees up the local port and the computer is now no longer listening for packets on that port. Of course you could keep the port open for the duration of the program, especially if you intend to send UDP request once in a while during execution.
Makes sense?

Error: Cannot connect to NTP server or NTP server is not running - Cisco IPS

This is different scenario here:
I have two Cisco IPS 4260-k9 and both are in production now.
One of the IPSs is configured with NTP and works fines, but another one is not.
When tried to configure when the device is ON and live in production and got the following error,
Error from CLI:
" Error: Cannot connect to NTP server or NTP server is not running "
Error from IME:
" Delivery failed.
err Unaccepable Value - cannot connect to the NTP server or NTP server is not running"
I am able to reach the NTP server, also the same NTP is working fine with other devices....
Am I doing anything wrong?
Please advise

Hi,
Now the error has changed:
Session.connect: java.net.SocketTimeoutException: Read timed out
I have increased the pooling interval to 1 Hr from 1 Min. Waiting for the next pooling interval result.
Guide me if I am heading right.... or anything else needs to be done.

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.

Hi rosch,
Based on your description, please check if disable the "Time synchronization" Integration service. Please refer
to the following operation.
In Hyper-V Manager, right click the DC and select “Settings…”.
In the left panel of Settings, navigate to Integration Services and click it.
Then in the right panel, please uncheck Time synchronization.
By the way, please check if can connect to the time server and UDP port was opened for NTP.
If any update, please feel free to let me know.
Hope this helps.
Best regards,
Justin Gu

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.

How to diagnose NTP server problem during boot-up?

We're having a problem on our campus network where Macs aren't able to use the time.apple.com NTP server to correct the time during boot-up. Once the user logs in, open the Date & Time pref pane causes the time to be corrected.
I've noticed this problem for quite a while but it's really been just a minor inconvenience. Then some users started using Boot Camp and it became a bigger inconvenience because their Mac time is wrong by 4 hours when they return to OS X from Windows XP. It has now become something that we need to address because we have set up a lab with iMacs all configured with Boot Camp and set up to authenticate off of our Active Directory server, which requires that the time be correct on the iMacs when the user tries to log in.
We'd like to monitor the network traffic on Mac during boot-up to see if we can figure out why this is happening. My person theory is that something that the network admins have the network configured to do when it first sees a new computer is causing enough of a delay in the DHCP process that the Mac doesn't have a network connection when the NTP server call would normally be made. The college has a DSL line that is not part of our network and NTP server time correction works correctly on it.
We're looking for the best way to capture the activity on the Mac and the network traffic at boot-up. Here are the things that we're looking into.
1) Verbose mode - Interesting looking but it goes by pretty quickly and I don't have time to read all of that info. Is this recorded in a log automatically somewhere or is there a way to capture this info?
2) Single user mode - I haven't been able to determine whether the NTP server call should have occurred by the time I get a prompt in Single User Mode. If so, is there a command I could use here that would give me a dump of activity and network traffic up to this point?
3) I have Interarchy which will let me record network traffic but as far as I can tell there's isn't a way to use this feature during boot-up. Am I wrong about that?
4) Someone suggested using Ethereal which appears to require Fink when installed. I can't tell if this will work during boot for if it's an app that I can only run after logging in (like Interarchy). Does anyone know how this works?
Any suggestions would be welcomed.

Turns out it was a network timing issue. The DHCP server wasn't providing the IP address quick enough (never figured out why, though).

NTP server unreachable through ASA firewall

Hi all,
I've configured a DMZ switch to point to an NTP server on on the Inside, but I get a debug message on the switch that says:
NTP: <NTP server IP address> unreachable
I'm confident that the NTP server is configured properly, as there are more than a dozen other hosts using it, successfully. The difficulty here is that the NTP packets are having to flow from the DMZ to the Inside. I have a rule set on the firewall that permits the IP address of the switch to connect to the IP address of the NTP server as follows:
access-list intdmz1_acl extended permit udp host <IP address of switch> host <IP address of NTP server> eq ntp
I can see the hit counter on this rule incrementing.
The firewall can ping the NTP server, and the NTP server can ping the switch, so I think routing is OK.
Output from the DMZ switch:

I'm guessing we should see some packets in the second capture, but we're not...
Does this help?

Hello Sue,
I have an iPad 3, iPad Mini and iPhone 5S and they are all sluggish on capitalisation using shift keys. I hope that Apple will solve the problem because it is driving me crazy.
I find using a Microsoft Surface and Windows 8 phone, which I also have, work as well as all the ios devices before the ios 7 upgrade.
It has something to do with the length of time that you need to hold the shift key down. The shift key needs to be held longer than the letter key for the capitalisation to work. For some reason, this is a major change in the way we have learnt to touch type on computers. I am having to relearn how to type!

Problems with AOL IMAP server connection on my BlackBerry Z10 STL100-3, and BB PlayBook 64GB WiFi

Problems with AOL IMAP server connection on my BlackBerry Z10 STL100-3, and BB PlayBook 64GB WiFi
Thursday 4:20am EST, 02-19-2015
Hi, My connection to the AOL IMAP server has suddenly failed - Says "Not Connected" on Accounts page
I haven't changed anything and this just started failing this morning.
I've saw same issue on my Blackberry PlayBook 64GB.
Is anyone else recently experiencing AOL IMAP Errors?
Solved!

Yes! Same thing happened suddenly to my Z10 this morning. No AOL.

Difference between using app server connection pooling and using the driver

Hi all,
How to get connection pooling with out application server and tomcat also?
What is the difference between using app server connection pooling and using the driver supported connection pooling?
Regards,
Murali

maybe the performance of App server pool is better than the JDBC pool,
for you don't know wether the implementation of the JDBC interface is good or bad.

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection

"[DBNETLIB] Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection"
After patches applied on patch Tuesday the database reports the above error.
All accounts are domain accounts and SQLServer uses Windows auth.
DCDIAG show no errors
All servers and DC have been restarted,
Message in db log confirms the connection is being denied due to trust.
Event log shows same rejection
Protocols enabled: named pipes, tcpip, memory
TESTS:
PortQry: "
TCP port 1433 (ms-sql-s service): LISTENING"
Connect with domain admin accounts works from multiple clients systems to DB.
Cannot connect with newly created domain admin account
Can connect if new admin account connect to server in terminal server session and uses UDL wizard or any other tool including isql.
New standard user also fails to connect.
NOTES:
I removed the SSL patch and the IE security update to see if that was an issue.
¯\_(ツ)_/¯

Has someone left the company or has an account of some nature been dropped/replaced?
Please click "Mark As Answer" if my post helped. Tony C.
Hi Tony,
Srry but No. We just installed the monthly updates.
I went back and found I had missed removing a patch. I missed the rollup for Windows Server 2003:
Event Type: Information
Event Source: NtServicePack
Event Category: None
Event ID: 4382
Date:  3/12/2015
Time:  12:26:04 PM
User:  NETTEST\admin
Computer: DATA1
Description:
Windows Server 2003 KB954920 was removed from your computer, and the previous Windows Server 2003 configuration was restored.
After I removed that is still didn't work but after about five minutes it started working.
I guess I ned to report that to MS after I research what might be changed to make the patch work.
Every time I get stuck and ask for help it seems to be just before I stumble on the solution.
Thanks for replying.
Well - maybe this will help someone else.
Thanks again for replying Tony
¯\_(ツ)_/¯
