+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Installation instructions for iftop
+$Id: INSTALL,v 1.3 2002/11/04 12:54:16 chris Exp $
+
+
+iftop is now autoconf/automake-enabled. You should be able to build it on
+common platforms by typing `./configure && make'.
+
+There is one gotcha, however, which is that some systems, such as FreeBSD,
+lack a working implementation of the gethostbyaddr_r(3) C library function. On
+such systems, you may want to use the --with-resolver=ares configure option to
+build a version of iftop which uses the ARES asynchronous DNS library for name
+resolution. An alternative is to use --with-resolver=netdb_1thread, which will
+make iftop run only one name resolution thread. This is not recommended.
+
+On some systems (notably Red Hat Linux) the libpcap header files are installed
+under /usr/include/pcap; on these systems, you should manually specify this
+when running configure, like this:
+
+    $ CPPFLAGS=-I/usr/include/pcap ./configure
+
+
+For historical interest, the old iftop makefile is included in Makefile.OLD.

+README for iftop
+$Id: README,v 1.8 2003/06/06 22:42:34 pdw Exp $
+
+Read the INSTALL file, manual page and source code for more information.
+
+iftop must be run as root.
+
+KNOWN ISSUES
+
+RedHat 7.2:
+
+There is a bug in the version of ncurses distibuted with RedHat 7.2 that
+will cause iftop to segfault.  The RPM in RedHat's Rawhide distribution
+fixes this.
+
+Slackware 8.1:
+
+You may need to upgrade your libpcap (by updating the tcpdump package) 
+in order to compile iftop.
+
+FreeBSD 4.7:
+
+This version of FreeBSD lacks a proper gethostbyaddr_r function. You should
+choose an alternative name resolution technique using the --with-resolver=...
+option to configure.
+
+Solaris:
+
+On Solaris, iftop has to run in promiscuous mode in order to capture
+outgoing packets.  iftop autoconfigures to run in promiscuous mode on
+Solaris, but will filter out non-broadcast packets which are not
+addressed to or from localhost.  On Solaris, the -p option merely
+disables that filter.
+
+If you have some other sort of system that behaves like Solaris in
+needing promiscuous mode, you can pass --enable-default-promiscuous to
+configure to enable this behavior.
+
+Cf. http://www.tcpdump.org/lists/workers/2002/02/msg00010.html
+
+The version of curses distributed with Solaris may not be sufficient for
+iftop's needs. You will probably need ncurses or similar.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+
+strncpy2() is like strncpy(), except that strncpy2() will always
+insure that the <dest> buffer is null terminated.  strncpy() will not
+NULL terminate the destination buffer if the <src> string is <n>
+characters long or longer, not counting the terminating NULL character.
+
+      STRNCPY2() IS NOT A COMPATIBLE REPLACEMENT FOR STRNCPY()!!
+
+There are two reasons to use strncpy2(). 
+
+The first reason is to guarantee that <dest> buffer's bounds are not
+violated.  In this case, <n> should be the size of the <dest> buffer
+minus one.
+
+i.e.,
+
+char tempstring[MAXLINE];
+
+strncpy2(tempstring, my_own_string, MAXLINE - 1);
+
+The second reason is to copy a specific number of characters from
+<src> to <dest>.  In this case, <n> should be the number of characters
+you want to transfer, not including the terminating NULL character.
+
+The following example copies "abc" into tempstring, and NULL
+terminates it.
+
+char tempstring[MAXLINE];
+
+strncpy2(tempstring, "abcdef123", 3);
+
+strncpy2() returns a pointer to the first character in <src> that was
+not copied to <dest>.  If all of <src> was copied to <dest>,
+strncpy2() will return a pointer to the NULL character terminating the
+<src> string.
+
+------------------------------------------------------------------------------*/

+strncpy2(char *dest, char *src, int n)
+{
+  int
+    i = 0;

+    *char_ptr;
+
+  /* -- */
+

+    return(src);

+
+Similar to strncat except that <n> is the size of the <dest> buffer
+(INCLUDING SPACE FOR THE TRAILING NULL CHAR), NOT the number of
+characters to add to the buffer.
+
+      STRNCAT2() IS NOT A COMPATIBLE REPLACEMENT FOR STRNCAT()!
+
+strncat2() always guarantees that the <dest> will be null terminated, and that
+the buffer limits will be honored.  strncat2() will not write even one
+byte beyond the end of the <dest> buffer.
+
+strncat2() concatenates up to <n-1> - strlen(<dest>) characters from
+<src> to <dest>.
+
+So if the <dest> buffer has a size of 20 bytes (including trailing NULL),
+and <dest> contains a 19 character string, nothing will be done to
+<dest>.
+
+If the string in <dest> is longer than <n-1> characters upon entry to
+strncat2(), <dest> will be truncated after the <n-1>th character.
+
+strncat2() returns a pointer to the first character in the src buffer that
+was not copied into dest.. so if strncat2() returns a non-zero character,
+string truncation occurred in the concat operation.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  --disable-dependency-tracking  speeds up one-time build

+  --enable-default-promiscuous If enabled, iftop will operate in promiscuous mode
+                          to capture outgoing packets
+
+Optional Packages:
+  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
+  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
+  --with-resolver=TYPE    Technique iftop should use for name resolution.
+                          Valid options are:
+			  netdb          use gethostbyaddr_r in multiple
+			                 threads.
+			  netdb_1thread  use gethostbyaddr_r and
+					 assume it is not reentrant.
+			  ares           use the MIT ARES asynchronous
+					 resolver library.
+			  forking        use the REALLY SUCKY forking resolver.
+			  guess          run experiments to guess a
+					 reasonable value.  Only works if you
+					 aren't cross-compiling.  This
+					 is the default.  guess will
+					 either select netdb or netdb_1thread.
+			  none           don't do name resolution.
+  --with-libpcap=WHERE    Where the libpcap packet-capture library is found.
+                          The pcap library should be installed  in WHERE/lib,
+                          and the header file in either WHERE/include or
+                          WHERE/include/pcap.
+                          default=look in standard locations
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.SH NAME
+iftop - display bandwidth usage on an interface by host
+
+.SH SYNOPSIS
+\fBiftop\fP \fB-h\fP |
+[\fB-nNpblBP\fP] [\fB-i\fP \fIinterface\fP] [\fB-f\fP \fIfilter code\fP] [\fB-F\fP \fInet\fP/\fImask\fP]
+[\fB-G\fP \fInet6\fP/\fImask6\fP]
+.SH DESCRIPTION
+\fBiftop\fP listens to network traffic on a named \fIinterface\fP, or on the
+first interface it can find which looks like an external interface if none is
+specified, and displays a table of current bandwidth usage by pairs of hosts.
+\fBiftop\fP must be run with sufficient permissions to monitor all network
+traffic on the \fIinterface\fP; see \fBpcap\fP(3) for more information, but on
+most systems this means that it must be run as root.
+
+By default, \fBiftop\fP will look up the hostnames associated with addresses it
+finds in packets. This can cause substantial traffic of itself, and may result
+in a confusing display. You may wish to suppress display of DNS traffic by
+using filter code such as \fBnot port domain\fP, or switch it off entirely,
+by using the \fB-n\fP option or by pressing \fBr\fP when the program is running.
+
+By default, \fBiftop\fP counts all IP packets that pass through the filter, and
+the direction of the packet is determined according to the direction the packet
+is moving across the interface.  Using the \fB-F\fP option it is possible to
+get \fBiftop\fP to show packets entering and leaving a given network.  For
+example, \fBiftop -F 10.0.0.0/255.0.0.0\fP will analyse packets flowing in and
+out of the 10.* network.
+
+Some other filter ideas:
+.TP
+\fBnot ether host ff:ff:ff:ff:ff:ff\fP
+Ignore ethernet broadcast packets.
+.TP
+\fBport http and not host \fP\fIwebcache.example.com\fP
+Count web traffic only, unless it is being directed through a local web cache.
+.TP
+\fBicmp\fP
+How much bandwidth are users wasting trying to figure out why the network is
+slow?
+
+.SH OPTIONS
+
+.TP
+\fB-h\fP
+Print a summary of usage.
+.TP
+\fB-n\fP
+Don't do hostname lookups. 
+.TP
+\fB-N\fP
+Do not resolve port number to service names
+.TP
+\fB-p\fP
+Run in promiscuous mode, so that traffic which does not pass directly through
+the specified interface is also counted.
+.TP
+\fB-P\fP
+Turn on port display.
+.TP
+\fB-l\fP
+Display and count datagrams addressed to or from link-local IPv6 addresses.
+The default is not to display that address category.
+.TP
+\fB-b\fP
+Don't display bar graphs of traffic. 
+.TP
+\fB-B\fP
+Display bandwidth rates in bytes/sec rather than bits/sec.
+.TP
+\fB-i\fP \fIinterface\fP
+Listen to packets on \fIinterface\fP.
+.TP
+\fB-f\fP \fIfilter code\fP
+Use \fIfilter code\fP to select the packets to count. Only IP packets are ever
+counted, so the specified code is evaluated as \fB(\fP\fIfilter code\fP\fB) and ip\fP.
+.TP
+\fB-F\fP \fInet\fP/\fImask\fP
+Specifies an IPv4 network for traffic analysis.  If specified, iftop will only
+include packets flowing in to or out of the given network, and packet direction
+is determined relative to the network boundary, rather than to the interface.
+You may specify \fImask\fP as a dotted quad, such as /255.255.255.0, or as a
+single number specifying the number of bits set in the netmask, such as /24.
+.TP
+\fB-G\fP \fInet6\fP/\fImask6\fP
+Specifies an IPv6 network for traffic analysis. The value of \fImask6\fP can be
+given as a prefix length or as a numerical address string for more compound
+bitmasking.
+.TP
+\fB-c\fP \fIconfig file\fP
+Specifies an alternate config file.  If not specified, iftop will use
+\fB~/.iftoprc\fP if it exists.  See below for a description of config files
+
+.SH DISPLAY
+
+When running, \fBiftop\fP uses the whole screen to display network usage. At
+the top of the display is a logarithmic scale for the bar graph which gives a
+visual indication of traffic.
+
+The main part of the display lists, for each pair of hosts, the rate at which
+data has been sent and received over the preceding 2, 10 and 40 second
+intervals. The direction of data flow is indicated by arrows, <= and =>. For
+instance,
+.nf
+
+foo.example.com  =>  bar.example.com      1Kb  500b   100b
+                 <=                       2Mb    2Mb    2Mb
+
+.Sp
+.fi
+shows, on the first line, traffic from \fBfoo.example.com\fP to
+\fBbar.example.com\fP; in the preceding 2 seconds, this averaged 1Kbit/s,
+around half that amount over the preceding 10s, and a fifth of that over the
+whole of the last 40s. During each of those intervals, the data sent in the
+other direction was about 2Mbit/s. On the actual display, part of each line
+is inverted to give a visual indication of the 10s average of traffic.
+You might expect to see something like this where host \fBfoo\fP is making
+repeated HTTP requests to \fBbar\fP, which is sending data back which saturates
+a 2Mbit/s link.
+
+By default, the pairs of hosts responsible for the most traffic (10 second
+average) are displayed at the top of the list.
+
+At the bottom of the display, various totals are shown, including peak traffic
+over the last 40s, total traffic transferred (after filtering), and total
+transfer rates averaged over 2s, 10s and 40s.
+
+.SH SOURCE / DEST AGGREGATION
+
+By pressing \fBs\fP or \fBd\fP while \fBiftop\fP is running, all traffic
+for each source or destination will be aggregated together.  This is most
+useful when \fBiftop\fP is run in promiscuous mode, or is run on a gateway
+machine.
+
+.SH PORT DISPLAY
+
+\fBS\fP or \fBD\fP toggle the display of source and destination ports
+respectively. \fBp\fP will toggle port display on/off.
+
+.SH DISPLAY TYPE
+
+\fBt\fP cycles through the four line display modes; the default 2-line display,
+with sent and received traffic on separate lines, and 3 1-line displays, with
+sent, received, or total traffic shown.
+
+.SH DISPLAY ORDER
+
+By default, the display is ordered according to the 10s average (2nd column).
+By pressing \fB1\fP, \fB2\fP or \fB3\fP it is possible to sort by the 1st, 2nd
+or 3rd column.   By pressing \fB<\fP or \fB>\fP the display will be sorted by
+source or destination hostname respectively.
+
+.SH DISPLAY FILTERING
+
+\fBl\fP allows you to enter a POSIX extended regular expression that will be
+used to filter hostnames shown in the display.  This is a good way to quickly
+limit what is shown on the display.  Note that this happens at a much later
+stage than filter code, and does not affect what is actually captured.  Display
+filters DO NOT affect the totals at the bottom of the screen.
+
+.SH PAUSE DISPLAY / FREEZE ORDER
+
+\fBP\fP will pause the current display.
+
+\fBo\fP will freeze the current screen order.  This has the side effect that
+traffic between hosts not shown on the screen at the time will not be shown at
+all, although it will be included in the totals at the bottom of the screen.
+
+.SH SCROLL DISPLAY
+
+\fBj\fP and \fBk\fP will scroll the display of hosts.  This feature is most
+useful when the display order is frozen (see above).
+
+.SH FILTER CODE
+
+\fBf\fP allows you to edit the filter code whilst iftop running.  This
+can lead to some unexpected behaviour.
+
+.SH CONFIG FILE
+
+iftop can read its configuration from a config file.  If the \fB-c\fP option is
+not specified, iftop will attempt to read its configuration from
+\fB~/.iftoprc\fP, if it exists.  Any command line options specified will
+override settings in the config file.
+
+The config file consists of one configuration directive per line.  Each
+directive is a name value pair, for example:
+.nf
+
+interface: eth0
+
+.Sp
+.fi
+sets the network interface.  The following config directives are supported:
+
+.TP
+\fBinterface:\fP \fIif\fP
+Sets the network interface to \fIif\fP.
+.TP
+\fBdns-resolution:\fP \fI(yes|no)\fP
+Controls reverse lookup of IP addresses.
+.TP
+\fBport-resolution:\fP \fI(yes|no)\fP
+Controls conversion of port numbers to service names.
+.TP
+\fBfilter-code:\fP \fIbpf\fP
+Sets the filter code to \fIbpf\fP.
+.TP
+\fBshow-bars:\fP \fI(yes|no)\fP
+Controls display of bar graphs.
+.TP
+\fBpromiscuous:\fP \fI(yes|no)\fP
+Puts the interface into promiscuous mode.
+.TP
+\fBport-display:\fP \fI(off|source-only|destination-only|on)\fP
+Controls display of port numbers.
+.TP
+\fBlink-local:\fP \fI(yes|no)\fP
+Determines displaying of link-local IPv6 addresses.
+.TP
+\fBhide-source:\fP \fI(yes|no)\fP
+Hides source host names.
+.TP
+\fBhide-destination:\fP \fI(yes|no)\fP
+Hides destination host names.
+.TP
+\fBuse-bytes:\fP \fI(yes|no)\fP
+Use bytes for bandwidth display, rather than bits.
+.TP
+\fBsort:\fP \fI(2s|10s|40s|source|destination)\fP
+Sets which column is used to sort the display.
+.TP
+\fBline-display:\fP \fI(two-line|one-line-both|one-line-sent|one-line-received)\fP
+Controls the appearance of each item in the display.
+.TP
+\fBshow-totals:\fP \fI(yes|no)\fP
+Shows cumulative total for each item.
+.TP
+\fBlog-scale:\fP \fI(yes|no)\fP
+Use a logarithmic scale for bar graphs.
+.TP
+\fBmax-bandwidth:\fP \fIbw\fP
+Fixes the maximum for the bar graph scale to \fIbw\fP, e.g. "10M". Note that the value has to always be in bits, regardless if the option to display in bytes has been chosen.
+.TP
+\fBnet-filter:\fP \fInet/mask\fP
+Defines an IP network boundary for determining packet direction.
+.TP
+\fBnet-filter6:\fP \fInet6/mask6\fP
+Defines an IPv6 network boundary for determining packet direction.
+.TP
+\fBscreen-filter:\fP \fIregexp\fP
+Sets a regular expression to filter screen output.
+
+.SH QUIRKS (aka they're features, not bugs)
+
+There are some circumstances in which iftop may not do what you expect.  In
+most cases what it is doing is logical, and we believe it is correct behaviour,
+although I'm happy to hear reasoned arguments for alternative behaviour.
+
+\fBTotals don't add up\fP
+
+There are several reasons why the totals may not appear to add up.  The
+most obvious is having a screen filter in effect, or screen ordering
+frozen.  In this case some captured information is not being shown to
+you, but is included in the totals.
+
+A more subtle explanation comes about when running in promiscuous mode
+without specifying a \fB-F\fP option.  In this case there is no easy way
+to assign the direction of traffic between two third parties.  For the purposes
+of the main display this is done in an arbitrary fashion (by ordering of IP
+addresses), but for the sake of totals all traffic between other hosts is
+accounted as incoming, because that's what it is from the point of view of your
+interface.  The \fB-F\fP option allows you to specify an arbitrary network
+boundary, and to show traffic flowing across it.
+
+\fBPeak totals don't add up\fP
+
+Again, this is a feature.  The peak sent and peak received didn't necessarily
+happen at the same time.  The peak total is the maximum of sent plus received
+in each captured time division.
+
+\fBChanging the filter code doesn't seem to work\fP
+
+Give it time.  Changing the filter code affects what is captured from
+the time that you entered it, but most of what is on the display is
+based on some fraction of the last 40s window of capturing.  After
+changing the filter there may be entries on the display that are
+disallowed by the current filter for up to 40s.  DISPLAY FILTERING has
+immediate effect and does not affect what is captured.

+DDEESSCCRRIIPPTTIIOONN
+       iiffttoopp listens to network traffic on a named _i_n_t_e_r_f_a_c_e, or on the  first
+       interface it can find which looks like an external interface if none is
+       specified, and displays a table of current bandwidth usage by pairs  of
+       hosts.   iiffttoopp  must  be run with sufficient permissions to monitor all
+       network traffic on the _i_n_t_e_r_f_a_c_e; see ppccaapp(3) for more information, but
+       on most systems this means that it must be run as root.
+
+       By  default, iiffttoopp will look up the hostnames associated with addresses
+       it finds in packets. This can cause substantial traffic of itself,  and
+       may  result in a confusing display. You may wish to suppress display of
+       DNS traffic by using filter code such as nnoott ppoorrtt ddoommaaiinn, or switch  it
+       off  entirely, by using the --nn option or by pressing rr when the program
+       is running.
+
+       By default, iiffttoopp counts all IP packets that pass through  the  filter,
+       and  the  direction of the packet is determined according to the direc-
+       tion the packet is moving across the interface.  Using the --FF option it
+       is  possible  to get iiffttoopp to show packets entering and leaving a given
+       network.  For example, iiffttoopp --FF 1100..00..00..00//225555..00..00..00 will analyse packets
+       flowing in and out of the 10.* network.
+
+       Some other filter ideas:
+
+       nnoott eetthheerr hhoosstt ffff::ffff::ffff::ffff::ffff::ffff
+              Ignore ethernet broadcast packets.
+
+       ppoorrtt hhttttpp aanndd nnoott hhoosstt _w_e_b_c_a_c_h_e_._e_x_a_m_p_l_e_._c_o_m
+              Count  web  traffic  only, unless it is being directed through a
+              local web cache.
+
+       iiccmmpp   How much bandwidth are users wasting trying to  figure  out  why
+              the network is slow?
+
+
+OOPPTTIIOONNSS
+       --hh     Print a summary of usage.
+
+       --nn     Don't do hostname lookups.
+
+       --NN     Do not resolve port number to service names
+
+       --pp     Run  in  promiscuous  mode,  so that traffic which does not pass
+              directly through the specified interface is also counted.
+
+       --PP     Turn on port display.
+
+       --ll     Display and count datagrams addressed to or from link-local IPv6
+              addresses.  The default is not to display that address category.
+
+       --bb     Don't display bar graphs of traffic.
+
+       --BB     Display bandwidth rates in bytes/sec rather than bits/sec.
+
+       --ii _i_n_t_e_r_f_a_c_e
+              Listen to packets on _i_n_t_e_r_f_a_c_e.
+
+       --ff _f_i_l_t_e_r _c_o_d_e
+              Use _f_i_l_t_e_r _c_o_d_e to select the packets to count. Only IP  packets
+              are  ever counted, so the specified code is evaluated as ((_f_i_l_t_e_r
+              _c_o_d_e)) aanndd iipp.
+
+       --FF _n_e_t/_m_a_s_k
+              Specifies an IPv4 network for traffic analysis.   If  specified,
+              iftop  will  only  include  packets  flowing in to or out of the
+              given network, and packet direction is  determined  relative  to
+              the  network  boundary,  rather  than to the interface.  You may
+              specify _m_a_s_k as a dotted quad, such as /255.255.255.0, or  as  a
+              single  number specifying the number of bits set in the netmask,
+              such as /24.
+
+       --GG _n_e_t_6/_m_a_s_k_6
+              Specifies an IPv6 network for traffic  analysis.  The  value  of
+              _m_a_s_k_6  can be given as a prefix length or as a numerical address
+              string for more compound bitmasking.
+
+       --cc _c_o_n_f_i_g _f_i_l_e
+              Specifies an alternate config file.   If  not  specified,  iftop
+              will  use  ~~//..iiffttoopprrcc if it exists.  See below for a description
+              of config files
+
+
+DDIISSPPLLAAYY
+       When running, iiffttoopp uses the whole screen to display network usage.  At
+       the  top  of the display is a logarithmic scale for the bar graph which
+       gives a visual indication of traffic.
+
+       The main part of the display lists, for each pair of hosts, the rate at
+       which  data  has been sent and received over the preceding 2, 10 and 40
+       second intervals. The direction of data flow is indicated by arrows, <=
+       and =>. For instance,
+
+       foo.example.com  =>  bar.example.com      1Kb  500b   100b
+                        <=                       2Mb    2Mb    2Mb
+
+       shows,  on  the  first  line, traffic from ffoooo..eexxaammppllee..ccoomm to bbaarr..eexxaamm--
+       ppllee..ccoomm; in the preceding 2 seconds, this averaged 1Kbit/s, around half
+       that  amount over the preceding 10s, and a fifth of that over the whole
+       of the last 40s. During each of those intervals, the data sent  in  the
+       other  direction was about 2Mbit/s. On the actual display, part of each
+       line is inverted to give a visual indication  of  the  10s  average  of
+       traffic.  You might expect to see something like this where host ffoooo is
+       making repeated HTTP requests to bbaarr, which is sending data back  which
+       saturates a 2Mbit/s link.
+
+       By  default,  the  pairs  of hosts responsible for the most traffic (10
+       second average) are displayed at the top of the list.
+
+       At the bottom of the display, various totals are shown, including  peak
+       traffic over the last 40s, total traffic transferred (after filtering),
+       and total transfer rates averaged over 2s, 10s and 40s.
+
+
+SSOOUURRCCEE // DDEESSTT AAGGGGRREEGGAATTIIOONN
+       By pressing ss or dd while iiffttoopp is running, all traffic for each  source
+       or  destination  will be aggregated together.  This is most useful when
+       iiffttoopp is run in promiscuous mode, or is run on a gateway machine.
+
+
+PPOORRTT DDIISSPPLLAAYY
+       SS or DD toggle the display of source and destination ports respectively.
+       pp will toggle port display on/off.
+
+
+DDIISSPPLLAAYY TTYYPPEE
+       tt  cycles  through the four line display modes; the default 2-line dis-
+       play, with sent and received traffic on separate lines,  and  3  1-line
+       displays, with sent, received, or total traffic shown.
+
+
+DDIISSPPLLAAYY OORRDDEERR
+       By  default,  the  display is ordered according to the 10s average (2nd
+       column).  By pressing 11, 22 or 33 it is possible to sort by the 1st,  2nd
+       or  3rd  column.    By  pressing  <<  or >> the display will be sorted by
+       source or destination hostname respectively.
+
+
+DDIISSPPLLAAYY FFIILLTTEERRIINNGG
+       ll allows you to enter a POSIX extended regular expression that will  be
+       used  to  filter hostnames shown in the display.  This is a good way to
+       quickly limit what is shown on the display.  Note that this happens  at
+       a  much later stage than filter code, and does not affect what is actu-
+       ally captured.  Display filters DO NOT affect the totals at the  bottom
+       of the screen.
+
+
+PPAAUUSSEE DDIISSPPLLAAYY // FFRREEEEZZEE OORRDDEERR
+       PP will pause the current display.
+
+       oo  will freeze the current screen order.  This has the side effect that
+       traffic between hosts not shown on the screen at the time will  not  be
+       shown  at all, although it will be included in the totals at the bottom
+       of the screen.
+
+
+SSCCRROOLLLL DDIISSPPLLAAYY
+       jj and kk will scroll the display of hosts.  This feature is most  useful
+       when the display order is frozen (see above).

+       lead to some unexpected behaviour.

+       iftop can read its configuration from a config file.  If the --cc  option
+       is  not  specified,  iftop  will attempt to read its configuration from

+
+
+QQUUIIRRKKSS ((aakkaa tthheeyy''rree ffeeaattuurreess,, nnoott bbuuggss))
+       There are some circumstances in which iftop may not do what you expect.
+       In most cases what it is doing is logical, and we believe it is correct
+       behaviour,  although  I'm happy to hear reasoned arguments for alterna-
+       tive behaviour.
+
+       TToottaallss ddoonn''tt aadddd uupp
+
+       There are several reasons why the totals may not appear to add up.  The
+       most  obvious  is  having a screen filter in effect, or screen ordering
+       frozen.  In this case some captured information is not being  shown  to
+       you, but is included in the totals.
+
+       A  more subtle explanation comes about when running in promiscuous mode
+       without specifying a --FF option.  In this case there is no easy  way  to
+       assign  the  direction  of  traffic between two third parties.  For the
+       purposes of the main display this is done in an arbitrary  fashion  (by
+       ordering  of  IP  addresses),  but  for  the sake of totals all traffic
+       between other hosts is accounted as incoming, because that's what it is
+       from  the point of view of your interface.  The --FF option allows you to
+       specify an arbitrary network boundary,  and  to  show  traffic  flowing
+       across it.
+
+       PPeeaakk ttoottaallss ddoonn''tt aadddd uupp
+
+       Again,  this is a feature.  The peak sent and peak received didn't nec-
+       essarily happen at the same time.  The peak total  is  the  maximum  of
+       sent plus received in each captured time division.
+
+       CChhaannggiinngg tthhee ffiilltteerr ccooddee ddooeessnn''tt sseeeemm ttoo wwoorrkk
+
+       Give  it  time.  Changing the filter code affects what is captured from
+       the time that you entered it, but most of what is  on  the  display  is
+       based  on  some  fraction  of  the last 40s window of capturing.  After
+       changing the filter there may be entries on the display that are disal-
+       lowed by the current filter for up to 40s.  DISPLAY FILTERING has imme-
+       diate effect and does not affect what is captured.

+%description
+iftop does for network usage what top(1) does for CPU usage. It listens to
+network traffic on a named interface and displays a table of current bandwidth
+usage by pairs of hosts. Handy for answering the question "why is our ADSL link
+so slow?".
