## Installation Instructions for Layer Four Traceroute
#######################################################
Instructions are provided for different platforms below.
#######################################################
On WINDOWS:
#######################################################
Building this program on Windows is possible without UNIX-like
compatibility environments. To compile the program, use the
Microsoft Visual Studio Express edition which is free and may be
downloaded from http://www.microsoft.com You must also download
and install the Windows Platform SDK which is available from the
same web site. The platform SDK provides the necessary Winsock
header files. Please read the documentation related to fully
installing the Windows Platform SDK for use with Visual Studio
Express or your alternative compiler to ensure all necessary
files are placed in the appropriate locations, specifically the
header files.
Using VS Express, you may build LFT by following these
instructions:
Open a Command Prompt window (cmd.exe), change directories to the
"lft" folder you downloaded, and type the following commands (from
inside the LFT folder):
"%VS80COMNTOOLS%vsvars32.bat"
nmake -f makefile.vc
This will create lft.exe and whob.exe in the current folder.
Of course, you may move the files wherever you choose. Depending
on the Windows platform, you may or may not have TCP raw sockets
functionality, causing TCP traces to fail. However, in this case
ICMP and UDP traces should still work.
You may also have to explicitly allow lft.exe to use the network
by creating a rule in Windows (or your 3rd-party) Firewall.
#######################################################
On UNIX-like operating systems:
#######################################################
Some special options to consider when running './configure' are:
1. Using '--enable-gtod' is useful on platforms where BPF timestamps are not
precise. This forces LFT to call gettimeofday() on each packet instead of
relying on the timestamp in the packet's pcap header.
2. Using '--enable-universal' will automatically compile universal binaries
on the Darwin/Mac OS X platform for PPC and Intel architectures.
Below are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory. After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
CPU-COMPANY-SYSTEM
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.
If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Operation Controls
==================
`configure' recognizes the following options to control how it
operates.
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
`--help'
Print a summary of the options to `configure', and exit.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options.

\`configure' configures this package to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--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.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-universal whether to include intel and ppc arch for Mac OS X
--enable-gtod use gettimeofday instead of pcap timestamps
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-pcap=PATH specify path to pcap library
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
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.
Report bugs to the package provider.

- no other changes
lft 3.31 / WhoB 3.5
----------------------
- Added #define for AI_NUMERICSERV undeclared on some platforms/versions
- No other changes
lft 3.3 / WhoB 3.5
----------------------
- Improved LFT target detection behind firewalls
- Updated LFT for newer pcap version defaults
- WhoB ignores comments [#,;] in input files
- Added LFT option -f to specify fake source address
- Applied many, many, many fixes from Juli M. of USA -- Thanks!

lft 3.2 / WhoB 3.2
----------------------
- Added support for 802.1q tagged VLANs
- Manual page corrections (thanks to Brett)
- WhoB will use Prefix WhoIs for bulk file resolution in
Cymru-compatible format with '-c' but Cymru will be used
with '-C'
lft 3.1 / WhoB 3.1
----------------------
- New configure options:
--enable-gtod Forces LFT to use gettimeofday() on each packet instead of
using the BPF timestamp. This is critical on platforms that have enabled
'fastts' or that do not have high-precision BPF timestamping.
--enable-universal generates binaries including both PPC and Intel architecture
(for users running Mac OS X/Darwin)
- Improved compatibility with NetBSD and Darwin/Mac OS X
- Added autoconf support for NetBSD
- Improved compatibility with older compilers (thanks to Sean)
- Updated autoconf bits and pieces
- By popular request, reversed the -g option of WhoB
WhoB now uses gigo mode by default unless -g is specified which turns
ON its parser and enables the other various options
lft 3.0
----------------------
- Completely refactored and now a workable library
- LFT has a new (-b) TCP Basic trace method that makes TCP traces NAT-friendly
- LFT has a new (-p) ICMP trace method that uses echo requests to trace paths
- Many memory issues fixed
- Cleanup of several 2.6b5-3.0b features
lft 2.6 / WhoB 2.0
----------------------
- LFT prints 'open' in the target block if the target dest port is open
- LFT indicates the reason it marked ports open/closed in verbose(2) output
- LFT prints an asterisk when it retransmits a packet after a timeout
- LFT uses Prefix WhoIs (bulk) or RISWHOIS (bulk) for netname resolution
- LFT has a new (-u) traditional UDP-based tracing feature
- LFT displays start and finish times/dates when using the (-T) option
- LFT has a new (-U) feature to display all times in UTC/GMT0
- LFT only shows time spent tracing/resolving at verbosity level 1 or higher
- LFT sets the ToS bit on outgoing IP datagrams when (-I) option is used
- LFT gets timevals from packets instead of calling gettimeofday()
- LFT won't be fooled into thinking there's a firewall on a gateway just
because adaptive mode ups the state waiting for replies that never come
- Improved LFT performance (removed gettimeofday() on each packet)
- WhoB/library uses Prefix WhoIs to resolve OrgNames and NetNames
- WhoB/library has improved support for RIPE NCC RIS and Prefix WhoIs
- WhoB supports bulk resolution (-f option) from an input file
- WhoB also supports one-per-line output (-cf option) from a bulk input file
- WhoB will use putenv() on Solaris who is missing setenv() to set TZ
- WhoB has a new (-g) feature to take input directly from the command line
and print output directly from Prefix WhoIs (referred to as GIGO)
- Added $DESTDIR support to Makefile (thanks Daniel)
- Fixed an off-by-one bug in LFT related to ASN display encountered when
a trace contains one or more neglected TTLs
- Fixed an off-by-one bug in LFT's verbose output regarding TTLs
- Fixed variable ordering in whois.c from 2.6b1 (thanks Erick)
- Numerous platform-specific improvements
- Reconfigured autoconf and segregated ./config/
- Updated autoconf components to v2.59
lft 2.5 / WhoB 1.5
----------------------
- Inclusive of betas 2.32 to 2.4x
- Added -z option to pseudo-randomize source port
- Added behavior to automatically select the most appropriate interface
based on routing (this was on the most wanted list)
- Improved OpenBSD compatibility (IP length nonzero)
- OpenBSD is now detected by autoconf (for configuring the above)
- Darwin is now detected by autoconf and its definition disables
some BSD features to make it compatible with MacOS X and Darwin
- LFT now indicates it has reached the target by printing a 'T'
character in the status display (if status is enabled)
- Cleanups were made to the verbose output levels (-VVV)
- Significantly revamped whois framework makes it easy to include
whois functionality into other programs
- Added -C and -R and -r options to force alternate ASN sources:
- (r)IPE RIS - special thanks to Rene Wilhelm @ RIPE NCC
- (C)ymru
- (R)ADB
- Default ASN source (-A) is now Prefix WhoIs (see pwhois.org)
- LFT now queries for ASNs in bulk format after completing
a trace if pwhois (default), RIPE NCC RIS, or Cymru is selected
- Added dst/src port autoselection based on user-supplied hostname
- Vastly improved standalone whois client "whob" see whob.8 (whob manpage)
- Makefile now installs 'whob' no-frills whois client (try ./whob)
- "Smart" mode is now referred to as "Adaptive" mode (-E)
lft 2.31
--------------------
- Fixed time precision on FreeBSD 5.3 (Thanks to Kurt Jaeger)
lft 2.3:
--------------------
- added WSAIoctl() call to select proper IF on windows based on dest (thanks Graham!)
- lowered max_retries to a default of 2
- cleaned up formatting related to -S option
- cleaned up verbose output to be more friendly
- cleaned up error messages
- updated manpage
- updated spec file
lft 2.2:
--------------------
- removed dependence on regex library
- removed dependence on INT_MAX
- fixed whois code to get the most specific netblock instead of the least specific netblock
- can now specify interface by IP instead of by name
lft 2.1:
--------------------
- Added autoconf support
- Ported to cygwin
- Fixed the Solaris and BSD makefiles (manpage install errors)
- Modified the whois code to resolve ASN and netname lookup
problems with RIPE entries. (-A) and (-N) code...
- Modified the whois code to support local-as
- Vastly streamlined the (-V) verbose output to cover the
important information (sequence, etc) of all packets
sent and received
lft 2.0 (and betas):
--------------------
- (-E) and (-F) shouldn't be used at the same time, now LFT knows that
- Implemented fixes that enable LFT to run under Solaris/SPARC (Jim McKim)
- Changed name from FFT to LFT (layer four trace)
- Added ICMP messages for codes 13-15
- Changed the (-P) option added in 1.99 to (-E) in order to force use of
the new "smart" engine
- Enhanced stateful firewall (packet filter) detection en route
- Engine: "smart" mode now tries FIN, SYN, etc table to get packets through
which dramatically improves its "find a way" capability
- Engine: "smart" mode now detects the BSD bug properly
- Engine: "smart" mode now detects firewalls in transit
- Compilation: made lft_queue.h the default for all OSs
- UI: lots of user interface changes
lft 1.99-beta(s):
--------------------
- Added Loose Source Routing feature (LSRR) [ <...>]
- Added (-N) Netblock name lookup feature
- Added (-A) ASN lookup feature
- Added (-P) option to automatically send 3 probes for more stats
- Added (-V) lots of verbose debugging information
- Added (-F) feature to revert to sending FIN packets
- Added (-T) option to show trace and resolution timings (LFT is fast)
- Added BSD 4.[23] and derivative (bug) inappropriate TTL detection
- Engine: Use sequence numbers as packet ID instead of destination port
numbers. This achieves a number of goals:
Return ICMP and TCP packets are more uniquely identified.
It is now possible to check the route for specific destination
port, which is important if route varies based on port (such
as with transparent proxying using a load balancing switch on
port 80) (thank you Ugen!)
- Engine: Send SYN packets. Variety of firewalls and NAT devices won't
pass through a single TCP packet that is not a part of established
connection, unless it carries SYN flag only (initial packet).
Pitfall: this may create useless PCB blocks on destination host,
if it does not use SYN cookies or some other SYN flood protection.
However it's better then not being able to use lft from behind
firewalls. (thank you Ugen!)
- Renamed (-H) max hops/ttl option
- UI cleaned up in several areas, especially result list & RTT display
- Detect local packet filter
lft 1.91:
---------------------
- Fixed Makefile.solaris (last time we'll see this before autoconf)
- added for Solaris
lft 1.9:
--------------------
- Default source port is now 53/tcp (dns-xfer)
- Configurable source port on command line through -p or host:port
- Configurable initial destination port on command line using -d
- Source and Destination ports use /etc/services for lookup
- Fixed a bug that created a gethostbyaddr() call even when the user
specified NOT to do reverse DNS lookups -- makes -n option way faster!
- Changed the way lft auto-detects the IP address of the interface selected
* now, we determine what address is assigned to the interface instead of
just getting the hosts's primary/default address and using it
* thanks, Aaron, for bringing this to our attention!
* thanks, Lane, for coming up with a platform-independent
way of making it work.
lft 1.8:
--------------------
- added option to suppress status indicator and only show trace (or errors)
* people using lft from a web page wanted this
- added option to select the network interface used as hop zero
* string length of device is tested to avoid potential buffer overflows
- modified the status bar to display:
Send mode: ->( / )
Recv mode: <{ }
Additional testing platforms for this release:
- Aaron Bentley (Univ Toronto) tested lft successfully under Debian Woody Linux
* Aaron also contributed a variation of net device selection -- thanks
lft 1.7:
--------------------
- added option to disable reverse DNS host lookups
- made several areas slightly more user-friendly
- modified the status bar to display:
Send mode: ->( / )
Recv mode: <( )
- changed "source" port from tcp/80 to tcp/25
most firewalls today permit tcp_established implicitly, not traffic
from tcp/80 explicitly, therefore we figured sending packets from
tcp/25 would be more likely to get through.
- modified initialization of 32-bit unsigned integer used to
calculate checksum
LFT now builds again under Solaris, but still miscalculates checksums
- fixed round trip time calculation
- several other minor tweaks
- tested under RedHat Linux, Darwin 5.5 (MacOS X v10.1)
lft 1.6 (nils):
---------------
- Great idea.

%description
LFT, short for Layer Four Traceroute, is a sort of 'traceroute' that
often works much faster (than the commonly-used Van Jacobson method) and
goes through many configurations of packet-filter based firewalls. LFT is the
all-in-one traceroute tool because it can use many different trace methods
and protocols such as ICMP, TCP, and UDP, as well as the RFC-1393 trace. More
importantly, LFT implements numerous other features including AS number
lookups based on global table prefix (not just the RIR), loose source routing,
netblock name lookups, et al. Also inlcudes a nifty whois client named 'whob'.

* Mon Aug 22 2005 Victor Oppleman
- Added -z option to pseudo-randomize source port
- Added behavior to automatically select the most appropriate interface
based on routing (this was on the most wanted list)
- Improved OpenBSD compatibility (IP length nonzero)
- OpenBSD is now detected by autoconf (for configuring the above)
- Darwin is now detected by autoconf and its definition disables
some BSD features to make it compatible with MacOS X and Darwin
- LFT now indicates it has reached the target by printing a 'T'
character in the status display (if status is enabled)
- Cleanups were made to the verbose output levels (-VVV)
- Significantly revamped whois framework makes it easy to include
whois functionality into other programs
- Added -C and -R and -r options to force alternate ASN sources:
- (r)IPE RIS
- (C)ymru
- (R)ADB
- Default ASN source (-A) is now Prefix WhoIs (see pwhois.org)
- LFT now queries for ASNs in bulk format after completing
a trace if pwhois (default), RIPE NCC RIS, or Cymru is selected
- Added dst/src port autoselection based on user-supplied hostname
- Vastly improved standalone whois client "whob" see whob.8 (whob manpage)
- Makefile now installs 'whob' no-frills whois client (try ./whob)
- "Smart" mode is now referred to as "Adaptive" mode (-E)
* Fri Nov 26 2004 Victor Oppleman
- Cleaned up various files, updated to support LFT 2.3
* Sun Apr 20 2003 Nils McCarthy
- Incorporated changes from Dag Wieers cleaning up
- a lot of the build process.
* Thu Mar 06 2003 Nils McCarthy
- revised to work with autoconf
* Mon Oct 28 2002 Florin Andrei
- first version
- v2.0-1

.Sh NAME
.Nm whob
.Nd display whois-type information of interest to Internet operators
.Sh SYNOPSIS
.Nm whob
.Op Fl h Ar whois-server
.Op Fl g
.Op Fl AaCcfhNnOopRrstuVv
.Ar query
.Sh DESCRIPTION
.Nm
queries various sources of whois information for data of interest to network
operators and their tracing and debugging tools.
.Pp
.Nm
output is designed to be easily parsed, or better yet, its functionality
can be added directly into your programs (see whois.h).
.Pp
The only mandatory parameter is the target host name or IP number.
Options toggle the display of more interesting data or change the sources
used to obtain that data.
.Pp
One key advantage of
.Nm
is its lookup of ASN information derived from the
global Internet routing table itself, as opposed to relying solely on what
has been registered in the RADB/IRR (see below). This data is, by default,
sourced from the global pWhoIs service. See www.pwhois.org
.Pp
Other options are:
.Bl -tag -width Ds
.It Fl A Ar ASN
Display all routing advertisements transiting the respective ASN. The
ASN may be supplied as the target argument, or a hostname or IP address may
be supplied and
.Nm
will resolve the ASN automatically.
.It Fl a Ar ASN
Display all routing advertisements made by the respective Origin-AS. The
Origin-AS may be supplied as the target argument, or a hostname or IP address may
be supplied and
.Nm
will resolve the ASN automatically.
.It Fl P Ar prefix
Display all routing advertisements related to the CIDR prefix supplied by the user.
.It Fl N Ar ASN
Display all networks registered to the ASN supplied by the user.
.It Fl O Ar ASN
Display all contact information on file for the ASN supplied by the user.
.It Fl g
Disable GIGO mode. By popular request, whob takes input directly from the command line
and passes it without modification to pWhoIs or whatever whois server is requested (-h).
The exact output is returned without any parsing. To enable parsing and the other
useful switches, disable GIGO mode by passing this (-g) option.
.It Fl R
Display the Origin-AS on record at the RADB/IRR (Routing Arbiter Database/Internet Routing Registry)
in addition the the Origin-AS provided by the prefix-based whois data source.
.It Fl n
Display the network name on record with the IP network allocation registry also
such as ARIN, RIPE, or APNIC.
.It Fl o
Display the organization name on file at the registrar.
.It Fl p
Display the AS-Path from the perspective of the current pwhois server. The pwhois
server may automatically exclude the initial, least specific ASN received from
the operator of the network to which it is connected (unless that ASN is the only/origin
ASN or unless it has multiple peers). Of course, this AS-Path is subjective. If you
rely on this and want AS-Paths that correspond to *your* network infrastructure, you
may want to install your own pwhois server. See the (-w) option and www.pwhois.org
.It Fl t
Display the date the route was last cached by the pWhoIs server.
.It Fl u
When possible, display dates in UTC/GMT instead of local time.
.It Fl h/w Ar host
Change the source of prefix-based whois data from the default (pWhoIs) to any
whois-compatible server of your choice (like your own).
.It Fl f Ar file
Read from the specified file (or from stdin if the argument is '-') and submit its contents
as bulk input to pwhois. The input will be buffered accordingly and subject to the
constraints of the current pwhois server. Output is written to STDOUT (which may be
redirected) and will not be parsed. Additional instructions to pwhois may be placed at
the beginning of the file, however they will only apply to the first buffer of pwhois
input. The first (left-most) field in each line of the file must be the IP address and
lines may be up to 255 characters in length.
.It Fl c
Change the source of prefix-based whois data from the default (pWhoIs) to Cymru.
See www.cymru.com for more details. When used with the -f option, this switch causes
.Nm
to use Cymru whois for bulk file resolution instead of pwhois.
.It Fl r
Display the Origin-AS and prefix according to RIPE NCC RIS (see www.ripe.net/projects/ris/).
When used with the -f option, this switch causes
.Nm
to use RIPE NCC riswhois for bulk file resolution instead of pwhois.
.It Fl s
Show the status of the (respective) pWhoIs server and exit(0)
.It Fl V
Display verbose/debug output. Use multiple 'V's for additional verbosity.
.It Fl v
Display this client's version information and exit(1)
.It Fl me|whoami
Display this host's public IP address and exit(0)

LFT TO-DO
---------
Features to ADD (not in any particular order)
- TCP-based tracing on windows doesn't work because of "security features"
- IPv6 support, or AF-independent source
- path MTU auto-discovery (RFC 1191)
- display min/avg/max/stddev RTT instead of just the sample
- asynchronus DNS queries
- implement target fingerprinting using TCP timestamps option (RFC 1323)

.Sh DESCRIPTION
The Internet is a large and complex aggregation of network hardware,
connected together by gateways. Tracking the route one's packets follow
(or finding the miscreant gateway that's discarding your packets) can be
difficult. (from traceroute(8))
.Pp
.Nm
was developed to automate a solution to the above, taking into
account that modern networks contain many configurations of load balancers,
proxies, and stateful firewalls.
.Pp
.Nm
implements numerous network tracing methods and strategies. Generally,
.Nm
sends various types of layer-4 probes utilizing the IP protocol `time to live'
field and attempts to elicit an
.Tn ICMP `time exceeded in transit'
response from each gateway along the path to some host. RFC 1393 Traceroute
Using an IP Option is also available as one of several tracing methods.
.Pp
.Nm
additionally listens for various messages along the way to assist network
managers in ascertaining per-protocol heuristic routing information.
.Nm
can optionally retrieve various information about the networks it traverses using
a variety of sources such as registries, routing arbiters, etc.
.Pp
The only mandatory parameter is the target host name or IP number.
Options toggle the display of more interesting data or change the variables
of the trace itself. The (-E/-e) adaptive option tries several combinations
of TCP states (changing flags inside the probes it sends) in order to improve
the chances of a successful trace and expose stateful packet filters.
.Pp
Other options are:
.Bl -tag -width Ds
.It Fl d Ar dport
Set
.Ar dport
as the destination TCP port of the probes LFT generates. Default is 80. This option is useful to see if packets follow a different route based on protocol destination, a likely scenario when load balancers or proxies are involved. This option may also bypass less sophisticated packet filter configurations.
.It Fl s Ar sport
Set
.Ar sport
as the origin TCP port of the probes LFT generates. Default is 53. This option is useful to see if packets follow a different route based on protocol source. This option may also bypass less sophisticated packet filter configurations.
.It Fl z
Automatically select a pseudo-random source port. This option may be useful if your local
packet filter or proxy doesn't allow you to use source ports outside of the dymanic range allocation.
.It Fl m Ar min
Set
.Ar min
as the minimum number of re-attempts to send per host. Default is 1 unless adaptive
(-E) mode is used.
.It Fl M Ar max
Set
.Ar max
as the maximum number of re-attempts to send per host. Default is 3.
.It Fl a Ar ahead
Set
.Ar ahead
as the number of hops forward to query before waiting for a response. Default
is 5.
.It Fl c Ar scatter ms
Set
.Ar scatter ms
as the minimum number of milliseconds to wait between sending probes. Default
is 20.
.It Fl t Ar timeout ms
Set
.Ar timeout ms
as the maximum number of milliseconds to wait before assuming a probe was
lost/discarded. Default is 1000.
.It Fl l Ar min ttl
Set
.Ar min tll
as the minimum TTL (time-to-live) on outgoing probes (essentially, the
first hop in the line that you want to display). Default is 1.
.It Fl q Ar ISN
Set
.Ar ISN
as the ISN (initial sequence number) of the first probe. If unset, one will be
automatically generated using a pseudo-random, time-seeded algorithm.
.It Fl L Ar length
Set
.Ar length
as the size of probe packets in bytes. This includes layer-3 and layer-4 headers, but
does not include layer-2 headers. For example, setting the length to 1500 would create
a 1500-byte probe packet which would result in a 1514-byte frame on an Ethernet network.
.It Fl D Ar device
Set
.Ar device
as the network device or address to receive traffic. (e.g., "en1" or "1.2.3.4") If unset,
.Nm
will attempt to determine and acquire the appropriate interface based on routing.
.It Fl f Ar device
Set
.Ar device
as the network device or address to transmit traffic. (e.g., "en1" or "1.2.3.4") If unset,
.Nm
will attempt to determine and acquire the appropriate interface based on routing.
This serves to operate
.Nm
in a passive mode where you may transmit from a (potentially) spoofed IP address on one
interface, yet receive on another. This allows you to trace from a different
IP address whose traffic you can see in order to intercept replies.
.It Fl H Ar ttl
Set
.Ar ttl
as the maximum TTL, essentially the maximum route traversal distance in
hops. Default is 30.
.It Fl G Ar icons path
Set
.Ar icons path
as the path to GraphViz icons in connection with GraphViz output.
.It Fl I
Set the ToS (Type of Serice) bit on outgoing IP datagrams. The ToS will
be set to the differentiated services request minimize-delay.
.It Fl i
Disable "stop" on ICMP other than TTL expired.
.It Fl n
Print addresses numerically rather than symbolically and numerically.
Disables use of the DNS resolver completely.
.It Fl h
Print addresses symbolically rather than symbolically and numerically. If
the DNS resolver fails to resolve an address, the address is printed numerically.
.It Fl E/e
Enable use of the adaptive engine which tries several combinations of TCP states
(changing flags inside the probes it sends) in order to improve
the chances of a successful trace. The engine also displays other useful
information such as stateful inspection firewalls or broken IP stacks
encountered along the way.
.It Fl F
Enable use of TCP packets with the FIN flag set. This strategy fools unsophisticated
packet filters that don't maintain a proper state table. Such devices will forward the packet
to its destination rather than filter it, assuming a handshake has already taken place and
the probes are part of an existing and valid TCP stream.
.It Fl u
Enable use of UDP-based probes instead of TCP-based probes. This strategy is similar
to the traditional traceroute method, but many of LFT's other options (such as source
and destination port selection) are still available. By default, LFT's UDP probes
have a small payload (unlike LFT's TCP probes that carry no payload).
.It Fl N
Enable lookup and display of network or AS names (e.g., [GNTY-NETBLK-4]). This
option queries Prefix WhoIs, RIPE NCC, or the RADB (as requested). In the case of
Prefix WhoIs or RADB, the network name is displayed. In the case of RIPE NCC, the
AS name is displayed.
.It Fl P
Enable RFC 1393 tracing method using ICMP and an IP option. While this strategy
has been formalized in an RFC, few network equipment vendors support it.
.It Fl p
Enable use of ICMP-based probes instead of TCP-based probes. This strategy
is sometimes the fastest, however firewalls commonly filter ICMP at network borders.
ICMP probes are echo request (ping) packets.
.It Fl b
Enable TCP basic tracing method. Unlike the default method, the basic method generates
TCP probes without relying upon sequence numbers being conveyed correctly. This
makes LFT more comptabile with networks employing NAT, but is slower than the default
method. TCP basic may also be used with adaptive mode (-E).
.It Fl A
Enable lookup and display of of AS (autonomous system) numbers (e.g., [1]).
This option queries one of several whois servers (see options 'C' and 'r')
in order to ascertain the origin ASN of the IP address in question. By
default, LFT uses the pWhoIs service whose ASN data tends to be more accurate
and more timely than using the RADB as it is derived from the Internet's global
routing table. See www.pwhois.org
.It Fl r
Force use of the RIPE NCC RIS whois service to lookup ASNs. This is an alternative
source of timely ASN-related information built using the Internet's global
routing table. See www.ripe.net/projects/ris
.It Fl C
Force use of the Cymru whois service to lookup ASNs. This is an
alternative source of timely ASN-related information built using the
Internet's global routing table. See www.cymru.com
.It Fl R
Force use of the RADB whois service to lookup ASNs. This tends to be quick,
but incomplete and usually inaccurate with regard to the 'actual' Internet
routing table. See www.radb.net
.It Fl T
Enable display of LFT's execution timer. This option places timers on the
trace itself and on lookups and name resolution to show where LFT is spending
its time, waiting on resolvers, or processing trace packets. Use with -V (verbose)
to display additional detail.
.It Fl U
Display all times in UTC/GMT0. This option also enables the -T option automatically.
.It Fl S
Suppress display of the real-time status bar. This option makes LFT show its
completed trace output only, no-frills.
.It Fl x
Enable XML output and suppress all other output to stdout.
.It Fl g
Enable GraphViz output and suppress all other output to stdout.
.It Fl y
Enable network seam testing in connection with GraphViz output.
.It Fl V
Display verbose output. Use more V's for more info.
.It Fl v
Display version information, then exit(1).
.El
.Pp
Any hosts listed after these options and before the final host/target will comprise
the loose source route. Since network operators have security concerns
regarding the use of source routing, don't expect the LSRR options
to do anything for you in most public networks.

21 [target] vnsc-bak.sys.gtei.net (4.2.2.2) 11.2ms
.Ed
.Pp
The (-S) option was used to suppress the real-time status bar for clean output.
LFT's "**" notifiers in between hops 10 and 21 represent additional useful information: the first is a "[neglected]" indicator that lets us know that none of the probes sent with the TTLs indicated elicited responses. This could be for a variety of reasons, but the cause of this specific occurrence is described in the next informative message which indicates that this is likely the result of a bug in
the 4.[23]
.Tn BSD
network code (and its derivatives): BSD 4.x (x < 3)
sends an unreachable message using whatever TTL remains in the
original datagram. Since, for gateways, the remaining TTL is
zero, the
.Tn ICMP
"time exceeded" is guaranteed to not make it back
to us. LFT does its best to identify this condition rather than print
lots and lots of hops that don't exist (trying to reach a high enough TTL).
.Pp
Now, using the adaptive engine option:
.Bd -literal

.Sh TROUBLESHOOTING
If traces don't appear to go anywhere, there are a number of things to try.
If you are receiving an error related to permissions, be sure the
.Nm
executable is set-uid root so it may execute with root-level permissions
required to utilize raw sockets on most operating systems.
.Pp
If you do not receive permissions-related errors, but traces still don't go
anywhere, first activate verbose output by adding -VV to your command line
options. Then, reading the verbose output, if you see trace
probes going out, but no replies being detected (as indicated by "RCVD" tags),
you may: Use the TCP basic (-b) method if you wish to use TCP probes and you
fear NAT may be causing your trace to fail. Alternatively, select a different
trace method and protocol such as UDP (-u) or ICMP (-p).
.Pp
If you are attempting to use RFC 1393 (-P) and your trace is failing, this is
likely because network equipment somewhere in the path does not conform to
RFC 1393. Your only option is to select an alternative tracing method or protocol.
.Pp
If you are attempting to utilize adaptive mode (-E/-e) and traces fail, first
try enabling NAT compatibility using TCP basic (-b). If traces still fail, the
most likely reason is a close-proximity stateful firewall in your network, which
prevents this feature from working.

.Sh HISTORY
The
.Nm
command first appeared in 1998 as 'fft'. Renamed as a result of confusion with fast fourier transforms,
.Nm
stands for 'layer four traceroute.' Thanks also to Nils McCarthy for writing 'FFT', LFT's predecessor.

/*
* This file defines five types of data structures: singly-linked lists,
* singly-linked tail queues, lists, tail queues, and circular queues.
*
* A singly-linked list is headed by a single forward pointer. The elements
* are singly linked for minimum space and pointer manipulation overhead at
* the expense of O(n) removal for arbitrary elements. New elements can be
* added to the list after an existing element or at the head of the list.
* Elements being removed from the head of the list should use the explicit
* macro for this purpose for optimum efficiency. A singly-linked list may
* only be traversed in the forward direction. Singly-linked lists are ideal
* for applications with large datasets and few or no removals or for
* implementing a LIFO queue.
*
* A singly-linked tail queue is headed by a pair of pointers, one to the
* head of the list and the other to the tail of the list. The elements are
* singly linked for minimum space and pointer manipulation overhead at the
* expense of O(n) removal for arbitrary elements. New elements can be added
* to the list after an existing element, at the head of the list, or at the
* end of the list. Elements being removed from the head of the tail queue
* should use the explicit macro for this purpose for optimum efficiency.
* A singly-linked tail queue may only be traversed in the forward direction.
* Singly-linked tail queues are ideal for applications with large datasets
* and few or no removals or for implementing a FIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.
