Nntp installation

No special configuration should be needed for the majority of routers, as support for NTP UDP packets on port is already built-in. These recommendations have changed with the various software releases, so it's best to check the VMware Web site for the current ideas.

With the Microsoft Hyper-V software, some suggestions from Steve Walker who needs good timekeeping for the excellent Plane Plotter software are:.

Steve Walker comments: I made sure the Hyper-V Time Synchronisation Service is started, as this will then allow the client to sync its time with the host. Of course, it has to sample pretty frequently to get that value, but fortunately I have a physical NTP server thanks!

They have a server component, too. You can pick a free evaluation of the software if you've not seen it and want to take a look. They did a great job. Check after a few minutes, to allow the program to connect to the Internet. If you are comfortable working with the command-line, obtain a command prompt Start, All Programs, Accessories, Command Prompt; or Windows-key -R, cmd , and simply enter the command:.

Note that the "-pn" must be lower-case, and that there must be a space between the "ntpq" and the "-p". An alternative command which may work a little quicker is "ntpq -pn". You should get output similar to the display below. Alternatively, from the Start menu, select Meinberg, Network Time Protocol, Quick NTP status - which gives you a handy ntpq display which automatically refreshes every ten seconds. This screen-shot was taken immediately after starting, so the poll is 64, and the reach only"1".

What is reach? Note that the two screen-shots below were taken with "ntpq -p", which includes the resolution of numbers to names. Using the "-pn" version suggested above is quicker.

This likely indicates that all is well. Meinberg provide further information here. Once basic operation is OK, if you wish to experiment I recommend you update to a more recent version , as the one in the Meinberg install is the "stable" release, but the "development" versions have some performance and operational advantages. NTP s a network application, so the basics of troubleshooting any network application apply.

In today's Windows environments:. Note that NTP has a maximum clock error it will correct of ppm But there is a work-round reported by one user - set up a scheduled task to run twice or more often a day to stop and restart the NTP service. You can also tell NTP what your clock drift rate is and that may help.

If you use the Meinberg menus to stop, start or restart NTP on Windows Vista, Windows-7 or later, you will likely get the error message above. This is because administrator privilege is needed to stop and start services. The solution is to right-click the menu item, and select "Run as administrator".

You can use the Windows Event Viewer to look at events which NTP records as a help in diagnosing more difficult issues. Look at the Application log by clicking on "Application":. You will see a list of events from all sources, not just NTP, with the most recent events at the top. Now use the View Filter Now double-click on one of the NTP events, in particular those with an Error status and the red cross. There is more information about using the Event Viewer on the Internet, for example, here.

You will get some event information messages as NTP starts and these are quite normal, and you will get occasional messages during the normal running of NTP. Look out for those which indicate failure. You can check that the NTP service is running and, perhaps more importantly that the W32Time the older Windows time service is stopped using the Services applet.

If the file ntp. A new feature in ntp So your clock must be well behaved, but need not be quite so close to correct. There are two steps to using this new functionality:. Whilst I haven't tried this myself, I guess you would try and get a value in the ntp.

Have patience! If you have some power-saving features enabled, you may try disabling those features and see whether NTP's performance improves.

On Windows Server , bit, release 2, I needed to run ntpd. Right click and go to properties of ntpd. Select compatibility tab and check "Run as Administrator" for all users. In the service settings select "local system account" instead of the special account created by setup.

It seems for me, only "local system account" has necessary rights to access "windows time". I don't understand why Try using ntpq -p The NTP Time Server Monitor only needs to be run as Administrator if you want to use the start and stop service commands, and this is to be expected. I installed NTP 4. In particular, I was able to avoid both a using 'Run as Administrator' compatibility mode on ntpd.

On my machine, before the change system tim e permission was enabled, I would see these error messages in the Application Event Log:. This machine has both IPv4 and IPv6 enabled so I suspect it's nearly always the Change system time security policy not being modified. The Meinberg site uses NTP 4. The command:. If you do want to experiment:. Any problems and you simply reverse the steps and use the version you saved in step 1. The later versions of NTP offer more options, and fix a few bugs.

If you want the most recent version- see below. With NTP 4. NTP will determine how many servers it should connect to automatically, and it may be more than the few from a default installation. Perhaps of more significance is that NTP monitors the connectivity to each server in a "pool", and if a server goes down it will try to connect a different one, thus maintaining a good number of working servers.

The pool directive introduces a new line to the ntpq -pn output - don't be put off by the line showing stratum, this is normal, and the pool servers below that line will show normal connectivity.

The top four servers are local to my network, and those below the. The maxpoll 7 in the configuration is to work round a different problem with some versions of Windows where a system call limits the precision with which the clock rate can be set.

If you are fault-finding, you may note that some parameters are passed to the service at startup:. Around Aug Windows Defender registered ntpd. Copy to Clipboard. Configure the Windows time service to start automatically. Optionally, restart the Windows time service using the graphical interface. Create a Firewall rule to allow the input of packets on the NTP port. You have finished the installation of the NTP server on Windows. Tutorial Windows - NTP server verification.

You have finished the NTP server configuration on Windows. To list some statistics about a newsgroup and print the subjects of the last 10 articles:. To post an article from a binary file this assumes that the article has valid headers, and that you have right to post on the particular newsgroup :. An optional timeout can be specified for the socket connection. If the optional flag readermode is true, then a mode reader command is sent before authentication is performed.

Reader mode is sometimes necessary if you are connecting to an NNTP server on the local machine and intend to call reader-specific commands, such as group. Raises an auditing event nntplib. All commands will raise an auditing event nntplib.

Changed in version 3. Please read Security considerations for best practices. All other parameters behave the same as for NNTP. However, some servers only support the former. Derived from the standard exception Exception , this is the base class for all exceptions raised by the nntplib module.

Instances of this class have the following attribute:. The response of the server if available, as a str object. Exception raised when a reply is received from the server that does not begin with a digit in the range 1—5.

An integer representing the version of the NNTP protocol supported by the server. In practice, this should be 2 for servers advertising RFC compliance and 1 for others. A string describing the software name and version of the NNTP server, or None if not advertised by the server.

Many of the following methods take an optional keyword-only argument file. When the file argument is supplied, it must be either a file object opened for binary writing, or the name of an on-disk file to be written to. The method will then write any data returned by the server except for the response line and the terminating dot to the file; any list of lines, tuples or objects that the method normally returns will be empty. Send a QUIT command and close the connection. Once this method has been called, no other methods of the NNTP object should be called.

Return the welcome message sent by the server in reply to the initial connection. The primary purpose of both protocols is very same. NNTP Server Status 3XX means the Server has received the message, but the message is unclear, and it requires further information to successfully execute the message request.
