Captrap Main Page

Captrap is a program for displaying network data transfer information. Different sets of data (mostly graphs) are divided into separate 'views'. Each view can be set to show information about bytes or packets. To get started, try clicking the link for 'Basic Information' or 'Interval Graphs', below.
