I am making available some Windows network tools that I have developed for my own use.  

Purely amateur use of these programs is free of charge, but use of these programs for any commercial or for-profit purposes requires registration.  If you like these programs, and wish to say "Thank you", or if you want technical support, you can register my Network Tools.

FTPpie

Your ISP offers you 30MB of disk space, but doesn't tell you how much space is used!  This tool enables you to get a usage piechart from your FTP service, showing which directories are taking the most space, and to drill down into those directories to see which are the largest files.  Simply double-click on a pie segment to drill down!

FTPpie is recommended by Blueyonder (UK broadband ISP).

V1.4.0 approximate folder space occupied as well, trap potential error with UNIX servers, don't require the Borland VCL40 run-time library

  Download Download FTPpie V1.4.0, 254245 bytes, revised 2003 Mar 26

Simply enter your user details and click on the Open site button:

Site details form

and you will see the program working to retrieve your Web space usage details.  Please note that the site name and directory details will be different for your ISP.  Once the program has finished, a pie-chart like the one below will be displayed, and you can double-click on a directory to drill down and see its contents.  This makes it very easy to clear out the maximum space with the minimum effort!

Blueyonder Users Update

For the recently released PWP2 service you will specify your address differently. Your old FTP upload address was: www.<aliasname>.pwp.blueyonder.co.uk, but instead you should now use: ftp.pwp.blueyonder.co.uk and enter your <aliasname> and <password> in the site details dialog.

 

NTPmonitor

This program allows you to compare your PC clock with a number of external sources.  You may have an Internet or GPS time service, but is your PC accurately synchronised to those sources, and how do they compare with one another?  For the most accurate synchronisation, your PC needs an NTP client, which will connect to an NTP service on the Internet.  Perhaps your ISP already provides such a service?

  • What is NTP?  It's the Network Time Protocol.  As you can see from the screenshot below, it enables you to keep your PC within a fraction of a second of the correct time.  Please see the NTP Web pages for more details about NTP.
  • Find out more about my own experiences of running NTP on Windows.
  • Take a look at my current NTP performance graphs.
  • Can you recommend any easy-to-use NTP software for Windows?  Yes, I have used and registered Tardis, a British product that runs under all versions of Windows and provides a very easy route into NTP.  Why not visit the Tardis home page?

NTPmonitor V5.0.0 - add graphing with choice of scale and reference filtering, make scan interval 60 seconds.  V5.0.2 - many small improvements, retain plot between invocations, improved display, report round-trip delay, remember settings between runs.  V5.0.4 - allow the use of any clock as a reference, where 20 minutes or more data is missing - don't plot, don't display NTP version number, as it's meaningless here.  V5.0.6 - minor compatibility update.

Screen-shot from NTP Monitor V5

Version 5 of the NTP monitor adds the ability to see trends over several hours by plotting a graph of the offsets against time.  These offset can either be relative to the local PC clock, or compared to a more accurate reference source.  The program allows you to filter the display in two ways, to improve the visibility of trend information:

  • by checking the Clean option, the reference clock is cleaned, so that glitches are removed.  Note the area very near the right-hand side of the plot where all the plots go below the axis in the top set, but are corrected in the middle set.  Regions where all clocks behave the same shows an effect in the reference.

  • by checking the Smooth option, the noise from random fluctuations is removed in all graphs (bottom set), but single transients become spread out.
