mfsnetdump

Dump network traffic as mfs packets.

This page reproduces the manual page mfsnetdump(8) as the product ships it: the text man mfsnetdump prints on a machine where the packages are installed. It is not edited here, and where it disagrees with the rest of this documentation, the documentation is the side kept against the sources. What the subject is: Command line tools.
