Banjo stuff - 27 May, 2008
As well as coding, I also play 5-String banjo. Checkout my new release of Bluegrass material, "Beyond Dark Hollow".
I also play banjo with a band called Beverley and the Clench Mountain Boys.
And also with Wires and Wood.

Updated - 6 Feb, 2008

I am not sure if there is any real need for WhatRoute now that we a vast range of UNIX tools at our disposal. However, I still receive requests for updates and modifications to the software, so I have resurrected the source and fixed many problems that have been brought to my attention in the last 4 years.

I dont expect that I will move the entire application to Universal Binary. To do so requires a major re-write and this would not seem to be justified, given that the initial reason I wrote the software was to solve networking problems on a platform that had no tools at all. Times have changed.

Thank-you to all of you have contacted me over the years since I first released the initial version (back on MacOS 7.5 from memory). Its a testament to Apple and Metrowerks that the software has survived largely intact since I first released it 1996, has run on 3 vastly different instruction sets (68K, PPC, Intel) and survived the major transitions in the OS that have struck over the years.

    It seems that the web server is mis-configured for .dmg files. If instead of a file download you get a bunch of garbage on your screen, click and hold the link until a pop-up menu appears. Then save the file to disk.

    Enhancements & Bug Fixes - WR 1.8.11
    Cleanup of WR 1.8.0 with much assistance from Mike Fischer. The rawrequest application is history and a helper app is included in the WhatRoute bundle.

    Enhancements & BugFixes - WR 1.8.0
    This is alpha level software. No new functionality, but it has been ported/updated to work under Carbon/MacOSx. There is also a version in the distribution that will run under MacOS 9 with no Carbon support.

    Enhancements & BugFixes - WR 1.7
    Hey - a non-beta release of WhatRoute - That hasn't happened for a while :-)
    A small (well quite big really) problem at work, prompted me to add a Ping Distribution window. This plots a frequency distribution of ping times and is quite useful for checking network performance.

    Fixed a bug that caused DNS Queries to lock up the machine if the DNS server is unavailable

    BugFixes - WR 1.6b5
    Version 1.6b5 adds the ability to do Traceroutes with ICMP packets instead of the more usual UDP. This may be of benefit if you are behind a fire-wall.

    Earlier versions of WhatRoute will fail under MacOS 9
    If you plan on using WhatRoute under MacOS9 you must get this newest version.

    This version works with MacOS 8.1

    Version 1.4.3 also available - This will not work on MacOS 9

    Thank-you to all those who have sent me feedback and encouragement (and bug reports).
    Fabrizio Oddone has been a major help in reporting/resolving problems. Thanks mate.
