-The I<Duration:> entry specifies the maximum time over which to capture,

-The I<File:> entry specifies the file to save to, as in the I<Printer

+The I<File:> entry lets you specify the file into which captured packets
+should be saved, as in the I<Printer Options> dialog above. If not
+specified, the captured packets will be saved in a temporary file; you
+can save those packets to a file with the I<File:Save As> menu item.
+
+The I<Use ring buffer> check box lets you specify that the capture
+should be done in "ring buffer" mode; the I<Number of files> field
+lets you specify the number of files in the ring buffer.
+
+The I<Update list of packets in real time> check box lets you specify
+whether the display should be updated as packets are captured and, if

+capture file size (although the operating system on which Ethereal is
+running, or the available disk space, may still limit the maximum size
+of a capture file).
+
+If "ring buffer" mode is specified, that field becomes the I<Rotate
+capture file very ... kilobyte(s)> field, and specifies the number
+of kilobytes at which to start writing to a new ring buffer file; the
+check box is forced to be checked, as "ring buffer" mode requires a file
+size to be specified.
+
+The I<Stop capture after ... second(s)> check box and field let you
+specify that Ethereal should stop capturing after it has been capturing
+for some number of seconds; if the check box is not checked, Ethereal
+will not stop capturing after some fixed time has elapsed.
+
+The I<Enable MAC name resolution>, I<Enable network name resolution> and
