System options 1

The General options let you set the following program behaviors:

  • Always show project settings when start capture.
    If checked, Javvin Packet Analyzer will always open the Project Settings dialog each time when you start a capture.
  • Always show maximum window when run Capsa.
    If unchecked, Javvin Packet Analyzer will remember the last setting of project window size and apply to next time when you run Capsa again.
  • Always show project warning when start capture.
    If unchecked, Javvin Packet Analyzer will not show the warning dialog when you start a new capture.
  • Automatically resolve host name of captured IP address.
    If checked, Javvin Packet Analyzer will automatically resolve the host name of captured IP addresses. Or else, you must resolve host name manually and separately by selecting the Resolve Host Name command from the context menu in the Project Explorer dock window.
  • Disable smooth scrolling.
    Instant scrolling will be enabled in effect if you check this option.
  • Disable list sorting if item count reaches:
    The sorting function will be disabled when the listed items reach the limitation. The default count is 2000.
  • TCP stream preview size:
    You may customize the preview size of TCP stream, the default size is 64 KB. When a TCP stream goes beyond the limitation, only the contents within the defined size are shown in the Stream view.
  • Keep recent open file count:
    Define a limit for keeping recent open file.
  • Reset
    Click this button to restore the predefined settings.

The Decoders dialog lists all decoders available in Javvin Packet Analyzer. By default, all decoders are activated and Javvin Packet Analyzer decodes packets using these decoders. If you disable a decoder in the list, Javvin Packet Analyzer will continue not to use that decoder every time it encounters a packet of the same type, as a result you can not view the decode information of that packet.
