tcpdump_to_db - Man Page
convert tcpdump textual output to fsdb
Synopsis
tcpdump_to_db [-T] < source.tcpdump > target.fsdb
Description
Converts a tcpdump textual 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.
