initialize $tcp_flags to zero when processing argus ICMP flows

================================================================================

revision 1.23
Be sure that NetFlow v5 fields are initialized even if the flow source
was flow-tools or argus, which don't always have those fields.
This is necessary now that flowdumper reports warnings in the perl
expressions supplied as arguments, and treats them as fatal.

ifdef ARGUS, include <sys/socket.h> and <net/if.h>.  This got things
to go with perl 5.004_04 under Solaris 2.6.  (I suspect that newer

revision 1.37
added "-o output_file" option so that the output file name can be a function

the AS path:
   $dst_as_path_arrayref, $dst_origin_as, and $dst_peer_as
   $src_as_path_arrayref, $src_origin_as, and $src_peer_as
This option requires ParseBGPDump and Net::Patricia to be loadable at

In the find_flow_tools subroutine: took out all the goofy stuff which

fixed a big problem with the previous revisions which were causing the
process size to grow incredibly large because temporaries weren't being
freed until after all flows in all files were processed.  In practive
this made flowdumper all but unusuable if you specified many file names
as the arguments because it would grow to 100s of megabytes and die wit
"out of memory"

================================================================================
RCS file: ./RCS/flowdumper.PL,v
2000-07-29 22:26:13-05
revision 1.21
added "-r" option to produce a raw flow file as output
(Primarily the intention of this option is to select flows to be redirected
into a file, or perhaps piped into another command for processing of raw
flows.  It would be ideal to use for preserving a subset of the flows from
a raw flow file into another file.)
================================================================================
RCS file: ./RCS/flowdumper.PL,v
2000-07-29 22:13:46-05
revision 1.20
added "-I" and "-E" options to define an initial and ending expression
to be evaluated, in addtion to that specified with "-e".  This allows
one to use this script for more complicated tasks which require

revision 1.20
got rid of some unnecessary white-space in $TCPFlags
================================================================================
RCS file: ./RCS/flowdumper.PL,v
2000-07-14 15:39:32-05
revision 1.19
changed "-s" output a bit (got rid of extra whitespace)

used new $ICMPTypeCode and $TCPFlags variables introduced in Cflow-1.019

added "-S" option for use with scripts or whatever that break due to the
introduction of the new $ICMPTypeCode and $TCPFlags info in the short
output format
================================================================================
RCS file: ./RCS/Cflow.pm,v
2000-07-14 15:30:32-05

revision 1.18
be sure we have Cflow 1.018 to avoid the bug with 1.017 which caused
the time not to be printed when invoking this script with "-s"
================================================================================
RCS file: ./RCS/Cflow.pm,v
2000-03-16 17:09:23-06
revision 1.18
fixed a long time bug that was causing $engine_type, $engine_id, $localtime,
$raw, $Bps, and $pps to not be exported when the user said they wanted
to import 'flowvars'

This was causing "flowdumper -s" to not print the time when used with the
previous revision of this module.
================================================================================
RCS file: ./RCS/Cflow.pm,v
2000-03-10 17:07:18-06
revision 1.17

fixed return value from find() so that it contains a proper "hit ratio"

updated POD regarding "hit ratio" return value from find()
================================================================================
RCS file: ./RCS/Cflow.pm,v
1999-10-28 14:57:48-05
revision 1.16
fixed some typos in error messages

added $Cflow::raw variable which contains the "raw" flow as read from
the input file

fixed up return value from "wanted" so that it would have the proper
syntax even when $count or $total are zero

(Sep 21)
================================================================================

revision 1.1
Initial revision
================================================================================
RCS file: ./RCS/flowdumper.PL,v
1999-03-21 16:54:38-06
revision 1.16
added "-s" and "-c" options to print flows in short format and to print
a count of # of flows "wanted" and processed, respectively.  (The "-c"
option requires Cflow 1.015.)

Changed the default format to that of CAIDA's flowdump(1) that is
distributed with cflowd.
================================================================================
RCS file: ./RCS/Cflow.pm,v
1999-03-21 16:50:25-06
revision 1.15
added Cflow::InetNtoA and Cflow::LocalTime packages so that I could tie
various flow variables.  This dramatically improves the performance of
this package by deferring the calls any calls to strftime(3) and
inet_ntoa(3) until the user refers to the resulting values.  In my
tests, this caused Cflow::find to execute in about 1/6 the time that
it took before.

had Cflow::find return a string containing a ratio of (# of wanted flows)/
(# of processed flows).  (This depends on the wanted function returning
a useful value indicating whether or not the given flow was "wanted" or
not.)
================================================================================
RCS file: ./RCS/Cflow.pm,v

lots of changes to understand the raw flow files produced by cflowd 2.0
rather than cflowd 1.3b2 which was what we handled previously.
(In this revision, the older flow file format is no longer handled.)

exported to their namespace (for convenience)

added more POD
================================================================================
RCS file: ./RCS/flowdumper.PL,v

revision 1.5
used Cflow 1.006 which has the $Cflow::localtime variable containing
the formatted date/time

added Getopts stuff and "-a" option to print all flows.
(The printing of the flow was split out into a separate sub-routine.)
================================================================================
RCS file: ./RCS/Cflow.pm,v
1998-09-30 15:57:39-05
revision 1.6

================================================================================
RCS file: ./RCS/Cflow.pm,v
1998-09-30 15:55:33-05
revision 1.5
added $Cflow::localtime as a convenience so that the caller doesn't
have to convert from a time_t ($Cflow::unix_secs) themselves.
================================================================================
RCS file: ./RCS/flowdumper.PL,v
1998-09-30 09:08:39-05
revision 1.4
pulled a bunch of code from here and organized it into "Cflow.pm".
================================================================================
RCS file: ./RCS/Cflow.pm,v
1998-09-30 09:06:00-05
revision 1.4
fixed a problem with the previous revisions which caused it to give up
on the rest of the flow files as soon as it warned "Invalid flow data file."
Now it will just move on to the next flow file.

reformatted some if-elsif blocks to a more switch-like structure after
reading the "perlsyn" man page.
================================================================================
RCS file: ./RCS/Cflow.pm,v
1998-09-30 08:29:35-05

RCS file: ./RCS/flowdumper.PL,v
1998-09-22 12:13:21-05
revision 1.3
used "flowpdu.ph" rather than pasting the perl version of the macros
defined there-in right in this file

checked that $index in the flow header had the right magic number.
Previously I didn't perform this test because cflowd erroneously always
puts 0xff in $index (even though as of this writing the correct value
would be 31.)  This validation is to be sure that someone isn't trying
to run this util on some flow file format that it doesn't understand.

added various comments, such as those describing which portions of the
cflowd sources where use to determine the formats used here.
================================================================================
RCS file: ./RCS/flowdumper.PL,v
1998-09-18 15:41:03-05
revision 1.2
made some changes in an attempt to speed things up

changed the validation code a bit to skip flows involving reserved ports
and to cache TCP flows on ports 12345 and 12346
