7

SYNOPSIS

9       dropwatch [-l <method> | list]
10

DESCRIPTION

12       dropwatch  dropwatch  is  an  interactive  utility  for  monitoring and
13       recording packets that are dropped by the kernel
14

OPTIONS

16       -l <method> | list
17              Select the translation method to use when a drop alert  arrives.
18              By  default  the  raw  instruction pointer of a drop location is
19              output, but by the use of the -l option, we can assign a  trans‐
20              lation  method so that the instruction pointer can be translated
21              into function names.  Currently supported lookup methods are:
22
23       kas - use /proc/kallsyms to lookup  instruction  pointers  to  function
24       mappings
