IPNetTuner
Current Version: 1.5.1 (March 22, 2002) / 1.7 (April 5, 2010)
IPNetTuner (formerly OT Advanced Tuner) is a control panel application (APPC) that allows you to change TCP/IP parameters under OpenTransport. Everything from adjusting TCP/IP window sizes to aborting keepalives is supported. It's the first utility of its type for the Macintosh, and is evidence itself of the many ways OpenTransport provides the Macintosh with one of the most flexible TCP/IP stacks available on any platform.
Version 1.5.1 (for "Classic" Mac OS) fixes a bug with ARP table which may have overwritten the table causing IPNetTuner to crash, as well as a bug with the Local Target popup menu.
The Mac OS X version, known as IPNetTunerX, supports over 20 adjustable parameters, including the TCP Window Size, Time Out intervals, Maximum Segment Size, and MTU. IPNetTunerX is a completely new implementation in Cocoa for the native BSD networking stack. The BSD stack is not as tuneable as Open Transport, but still supports a number of important parameters. The included sample tuning documents along with the Link Rate and TCP Rate tools make it easier than ever to test performance and verify the effect of network tuning.
Version 1.7 of IPNetTunerX - the first release in nearly two years - adds/changes the following:
- Update AirPort Signal tool to work on Snow Leopard.
IPNetTunerX is a $15 upgrade from the "Classic" version. See the overview page for more information.

These are applications that are newer and of potential interest, but which I haven't yet selected for permanent inclusion. Have a look, and let me know if you think they deserve to be part of the permanent collection!
