Perform this operation at application startup before opening any endpoints since it may rebuild the TCP/IP configuration (pressing Option during startup will force the stack to rebuild).

Monitor: pause and then restart monitor if DHCP lease expires.

The Subnet Calculator now shows the number of addresses in a subnet based on the mask.

January 14, 1997

Changed the name of the preferences file from "IP NetLink Prefs" to "IPNetMonitor Prefs" to match the new product name. If you are installing this version over a previously registered copy, you will need to re-enter your registration data, or rename the old preferences file so IPNetMonitor finds your registration data.

Removed the "look down" button from the Ping and Trace Route windows. The program automatically determines whether to do a lookup or reverse lookup based on which field is empty or contains the insertion point.

The Monitor tool now shows a running average in blue.

Horizontal and vertical grid lines have been added to the Monitor display.

Added 'clut' resource to specify colors for the Monitor display: background, grid, transmit, receive, average, small background, and small grid. If the background and grid color are the same, the horizontal graph scale is shown. If no 'clut' resource is found, use default colors from the standard palette.

Times less than 0.1 second are now displayed to three decimal places in the Test Connectivity window.

November 20, 1996

The Monitor tool now works with Ethernet and other data link providers.

A User Guide is now available including a tutorial on "Finding and Fixing Potholes on the Information Highway."

Added "Who Is" client. Select any destination from the Trace Route table and type Cmd-I to look up "Who Is" responsible for the corresponding top level network domain.

Invoking one tool from another transfers the corresponding data automatically. Cmd-R from the ping window will automatically start a Trace Route to the same address.

The Log Window now records each test and a summary of ping results.

Added edit fields to adjust "Limit" and "Delay" for Ping test (pings are now asynchronous).

The demo now expires 21 days after being installed.

The terms and conditions for use have been updated to reflect the programs commercial status.

A 68K version is now available (but Monitoring won't work until the OTModl$Proxy module is converted to ASLM).

September 24, 1996

Fixed a bug in the OTModl$Proxy STREAMs module that caused occaisional data corruption or crashes while monitoring.

You can select the results of a Trace Route test and copy them to the clipboard as plain text (for pasting into email messages). If you include the first row of the table in your selection, the table headings will also be copied as shown here.

<traceroute: 199.232.56.35>

Hop Sent Received Seconds IP Address Name

The line beginning "<traceroute: " is the URL for this trace. If you use Internet Config and have selected IPNetMonitor as the corresponding helper application, you can invoke a Trace Route to this address by command clicking in the URL. [Great if someone sends you email including the results of a traceroute, and you want to reproduce it.]

Fixed various cosmetic bugs.

Further testing reveals Open Transport will not autopush STREAMS modules above classic 'mdev's (MacPPP or FreePPP). To use the Monitor window, you'll need to use Apple's OT/PPP (the only OT Native PPP implementation I'm aware of at this time). I'm still investigating ways to work around this.

September 3, 1996

IPNetMonitor now remembers each window's size and location when the window is closed, and will restore windows to their previous position when opened.

IPNetMonitor remembers which windows we're open when you last quit the application, and will automatically re-open them when the application is started.

IPNetMonitor now handles the GURL Apple Event. If you use Internet Config, you can make IPNetMonitor the helper application for URLs of the form "traceroute://a.b.c/" or "ping://a.b.c/".

If the Monitor window is open when a GURL Apple Event is received, monitoring will be started before invoking the traceroute or ping.
