SYNOPSIS

dropwatch [-l <method> | list]

DESCRIPTION

dropwatch dropwatch is an interactive utility for monitoring and recording packets that are dropped by the kernel

OPTIONS

Select the translation method to use when a drop alert arrives. By default the raw instruction pointer of a drop location is output, but by the use of the -l option, we can assign a translation method so that the instruction pointer can be translated into function names. Currently supported lookup methods are:

kas - use /proc/kallsyms to lookup instruction pointers to function mappings

Tells the kernel to discontinue reporting dropped packets
