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.

Error 1201 In Information Store Using Exchange Server


Exchange Server follows transaction logging system. Information Store folder is comprised of related transaction logs along with storage groups. It means that Information Store is the most critical part of Exchange Server. Number of storage groups may vary according to the requirements of organizations and Exchange Server version being used. If the Information Store suffers inconsistencies or corruption, EDB Recovery will recover lost data in the absence of online backup.

Priv.edb and Pub.edb are two critical files of Exchange Server Storage Group. These files contain user mailboxes. If these files get corrupt, Exchange Server may return 4294966095 error and Information Store service may fail to start. The corresponding event entry in Event Viewer is -1201.

Apart from EDB corruption, -1201 Event ID may also generate if log files and EDB files are on different drives and due to some issues, log files are not available. To resolve the issue, user can follow these steps:

If online data backup is available, user can restore Information Store from it
If Information Store backup is unavailable or incomplete, user needs to use Eseutil repair utility to perform Hard Recovery. The process requires two basic considerations: backing up Mdbdata folder to avoid further data loss and ensuring that hard disk contains sufficient free space for Hard Recovery. Mdbdata folder contains all log files and storage groups of Exchange Server. However Exchange Server Repair requires following commands to be applied:

eseutil /p /ispriv /tx:\tempdfg.edb
eseutil /d /ispriv /tx:\tempdfg.edb
isinteg -fix -priv -test alltests
eseutil /p /ispub /tx:\tempdfg.edb
eseutil /d /ispub /tx:\tempdfg.edb
isinteg -fix -pub -test alltests
If problem persists, third party Exchange Server Recovery applications can be used on Mdbdata folder to repair damaged EDB files. These are the tools that can scan and repair damaged EDB files and extract user mailboxes without affecting data integrity.

Stellar Phoenix Mailbox Exchange Recovery is the most powerful edb recovery software. It extracts user mailboxes from damaged EDB files and restores them as individual PST files which can be used with Outlook. It supports Exchange Server 2003, 2000 and 5.5. It is compatible with Windows XP, 2003 and 2000.
Exchange Server 5.5
where x: is the drive containing the required free disk space.

NOTE: When the Information Store service has started, after the repair process, make a full online backup immediately.

What Is Python Web Programming


The python programming language is a modern web programming language that was originally conceived and developed by Guido van Rossum in the 1980s. Since that time, Python has evolved into a high-performance programming language that is modular and extensible. Some of the largest websites in the world are utilizing Python such as YouTube, Disqus, and Reddit. Python offers a number of features that make it an attractive programming platform including stability, portability, object-oriented development, a powerful standard library and a wealth of third-party modules or packages.


Python has been under active development since the late 1980s and is considered a mature programming language. The developers of the Python language conduct extensive functionality and regression testing to ensure the language remains bug-free and stable with each new release.


Python programming offers a number of features that make it an attractive option for web application development. Python applications are portable due to the fact that python interpreters are available for all modern operating systems and some embedded computing systems.

Object-oriented Development

The object-oriented nature of Python makes it an ideal first language for new programmers and easy to learn for programmers migrating to Python from other object-oriented languages. Python programming is intuitive and reinforces good program structure and object-oriented methodologies.

Standard Library

The standard Python library offers developers a plethora of features comparable to more complex languages such as C++ while maintaining simple and approachable language syntax. Comprehensive file-based I/O, database interactivity, advanced exception handling and a host of built in data types make Python appropriate for both web applications and general purpose programming. This makes python web programming an easy task for application developers seeking to transition to web application development.

Third Party Modules

Python is known for being a comprehensive language with extensive functionality included in the standard library. However, the growing popularity of python programming has led to a vast array of third-party packages, or modules, that extend Python’s functionality and allow the language to deal with unique programming challenges. For example, modules are available for handling non-standard database interactions and advanced cryptography functionality. There are also modules available for dealing with common tasks such as reading file metadata, rendering charts and compiling Python applications into standardized executable applications. Python web programming is made easier due to the availability of many web-centric modules to handle tasks such as e-mail, maintaining HTTP state, interacting with JavaScript, and other common web development tasks.
