tcpdump_to_db — convert tcpdump textual output to fsdb

Synopsis

tcpdump_to_db [-T] < source.tcpdump > target.fsdb

Description

Converts a tcpdump data stream to Fsdb format.

Currently it handles only TCP and silently fails on other traffic! Awaiting enhancement... you're welcome to help.

Options

-t or --daytime
Adjust times relative to the first timestamp. (Defaults on.)

This module also supports the standard fsdb options:

-d
Enable debugging output.
-i or --input InputSource
Read from InputSource, typically a file name, or "-" for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
-o or --output OutputDestination
Write to OutputDestination, typically a file name, or "-" for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
--autorun or --noautorun
By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The "--(no)autorun" option controls that behavior within Perl.
--help
Show help.
--man
Show full manual.
