NTP Server Systems The Network Time Protocol

NTP Server Operation

A NTP server can operate in three modes: unicast; anycast and multicast. In unicast and anycast modes, the client transmits a NTP request message to the server. The server responds with a NTP time message that the client uses for time synchronisation. In multicast mode, NTP time messages are broadcast at periodic specified intervals.

NTP Reference Clocks

Primary NTP servers can synchronise with a number of external reference time sources. The GPS (Global Positioning System) is often used to provide an accurate timing reference. There is also a number of national time and frequency radio broadcasts available. The WWVB radio time broadcast is transmitted from Colorado and covers most of the US. The DCF-77 radio time signal is broadcast from Frankfurt, Germany, and covers much of central and Western Europe. The MSF radio time signal is broadcast from Rugby, UK, and covers the British Isles and much of Western Europe. Other local time and frequency radio broadcasts include: TDF, France, and CHU, Canada.

NTP Versions

The current release of NTP is version 4. The only significant modification to the protocol between versions 3 and 4 is a slight header re-interpretation to accommodate IPv6.

SNTP Simple Network Time Protocol

SNTP is a simplification of the Network Time Protocol, where the complexities of the full-blown protocol are not required. SNTP can be implemented when the high synchronisation performance of NTP is not required. The message format of the SNTP protocol is almost identical to that of the NTP protocol. However, the complex subroutines designed to maintain a highly accurate synchronised time are removed or simplified. Small computers with reduced processing power, such as micro-controllers or monitoring equipment most often use SNTP. The SNTP and NTP protocols are fully interchangeable, a SNTP client can synchronise to a NTP server without any issues.

More Information: NTP RFC’s

The original Network Time Protocol was introduced in RFC 958 (Request for Comments: 958). The full NTP version 3 protocol and synchronisation algorithms are described in RFC 1305. The SNTP version 4 protocols are described in RFC 2030.

Whenever you constantly change your port of access, you get to further secure the data you have stored on the servers. Changing the port of access has also been known to greatly reduce cases of fraud or theft of credit cards.

Apart from the system that involves changing the port of access, there are other important things that you can do to improve your server security like setting up your server firewall . Hackers are able to switch off the system firewall remotely so ensure that you constantly ensure that the firewall system is always up . There is a phrase is server security called hardening . This term refers to the removal of unnecessary software on the hosting machine so that only the software required for hosting services is left installed.

When you know the necessary software installed, you can easily detect unwanted software and immediately get rid of it to restore your security . Server security can also be ensured by use of software that scans the system trying to detect weak points. Such software is very useful as it not only detects the open ports but it also has mechanisms of closing the unseen open gaps.

Even software running on the same computer as same as the individual customer computer, it absolutely work as a separate computer and for the need of the customer. It also has the privacy of the separate physical computer and can run just like a server computer if configured. The term VDS is less used for the same process compared to VPS, each of these can run their own operating system and can be independently rebooted, which helps the user a lot in configuring any process and using it. Partitioning of a single server is done so that it can be showed as multiple has been in practice since a long time, especially both on mainframe computer and mid range computers. It has become more popular with the development occurring day by day in case of virtualization of software and technologies for micro computers.

It bridges the gap between dedicated hosting services and shared web hosting services by giving independence of the VPS services in software terms. It cost less compared to physical dedicated servers. It runs at its own operating system and is capable of running any software on other operating systems some doesnt run in virtualized ones. There are two types of hosting, the first one is Unmanaged and other is unmetered. In the case of unmanaged one the customer is left to monitor and administer their own server and in the case of unmetered one, unlimited amount of data transfer is allowed on a fixed bandwidth line. Unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s.

Here the customer can use 3.33~ TB on 10 Mbit/s, 33~ TB on 100 Mbit/s and 333~ TB on a 1000 Mbit/s line. A VPS is also referred as cloud server it has two attributes which are- additional hardware resources can be added at runtime (CPU, RAM), and Server can be moved to other hardware while the server is running (automatically according to load in some cases). As an intermediary service between shared web hosting and dedicated server hosting, the actual hardware server is divided into several isolated environments. Each environment, or space of the hardware, has its own server software, mail server, and independent software instances and services. VPS hosting offers an extremely affordable hosting solution for business owners.

Tips to Optimize WordPress Running on Dedicated Server

This is a comprehensive guide or bunch of tips to Optimize WordPress Running on Dedicated Server. Though Dedicated Server is becoming a historic hosting option as Cloud Servers are currently dominating the most of the useful and successful blogs, still there are users who use dedicated servers and these few tips to optimize WordPress might help them.

Tips to Optimize WordPress Running on Dedicated Server – Reduce the Database Server’s burden/b>

In case of a dedicated server, the database server is actually running on the same physical server and using the same physical resource. MySQL has gone away, 508 resource limit reached messages are quite common due to increased number of plugins which are eating up the php memory. In case of a Dedicated Server, you frankly can not increase the php memory after a limit, which a Cloud Server easily can do as the cloud server’s RAM and Bandwidth is virtually not limiting.

These happens probably due to the fact, all the plugins try to use wp-cron.php or other same core file simultaneously. To avoid it, use database cache plugin plus reduce the number of not-so-needed plugins. If you need to reduce a plugin, which is SEO wise harmful – try to increase the php memory.

Tips to Optimize WordPress on Page Speed Score

Your WordPress blog should load within 2 – 3 seconds with a Page Speed score (by WebPageTest) should be over 90/100.
Using a Content Delivery Network, a Cache Plugin, some htaccess tricks can do it easily. All these, directly reduces the load on the main server.
Use an optimal theme, Thesis and Genesis framework with optimized child theme are among the best performers. Read our previously published tips to Optimize WordPress on the page speed front.
Use a cache server if needed

Tips to Optimize WordPress on the backend

Its quite bad if the WordPress backend is slow despite the fronend is fast – it simply increases your fatigue. You can use CDN to offload the static files, increasing the php memory.

Tips to Optimize WordPress Running on Dedicated Server

Frankly, there is no meaning to use a dedicated server for a WordPress blog now. Cloud Server and cloud Hosting from Rackspace or other reliable hosting brands not only reduces the cost, but also gives the pay as you go model, ensuring that your WordPress will never be short of Physical RAM or Bandwidth.

Dedicated server is probably a good option where a bit more security is needed – our usual blogs has nothing to hide, all pages are actually public; but still for a secure server, one must think of a colocation server rather than a dedicated server.

Also, a Virtual Dedicated Server is a very good cheaper alternative, sometimes a VPS can outperform a Dedicated Server at the same cost or less.
