FrameSeer

An updater has been released for FrameSeer. Significant improvement in non-dynamic capture performance. Testing on 500MHz G4 systems shows that FrameSeer can usually call upon tcpdump to capture 64-byte packet slices on a busy 100mbps Ethernet without significant loss (for those interested in the gory details, the bottleneck appeared to be in either the Unix pipes mechanism or Cocoa's NSTask API; FrameSeer now only uses NSTask/pipes for dynamic capture). Holding down the Option key when clicking on the Start button inverts the meaning of the Dynamic Display user preference. To give Administrators additional control over who may perform live captures, FrameSeer now supports three security states: All privileges revoked; Grant privileges to Administrators only (this is the first-launch default); and Grant privileges to all users (this was the default for earlier versions of FrameSeer). Filters in both the Filter Specification window and Filter Selection drawer now sort in alphabetical order by filter name. Where appropriate, filter presets now use protocol names rather than numbers. PPPoE presets in the Data Link Frame Type combo box of the Filter Definitions window now use the correct protocol numbers. A new user preference (Auto-Open Filter Drawer) controls whether the Filter Selection Drawer opens automatically whenever a new window opens. The preference is enabled by default. This is both a convenience for users who routinely select filters and also a way of helping new FrameSeer users to discover the filtering mechanisms. Frames where both the source and destination ports were unnamed did not appear in the Transport Protocol map. Such frames are now counted as "(other)". Horizontal labels in Protocol and Size tabs are fully visible in the default-size window. A new user preference (Save Document Location) saves the on-screen location and size of the last window closed and uses it as a hint for placement of new windows. The preference is disabled by default. See FrameSeer's online documentation for additional information. Internal decode tables updated to use latest IANA protocol numbers.
