(-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. lft-2.2/COPYING0100664000077400007740000000614507623002740011714 0ustar nilsnils MainNerve Public License for Open Source ---------- Copyright (c) 2002 MainNerve, Inc.

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. lft-2.2/Makefile.in0100664000077400007740000000272107656253466012745 0ustar nilsnils# # This file is part of LFT. # # The LFT software provided in this Distribution is # Copyright 2002 MainNerve, Inc. # # The full text of our legal notices is contained in the file called # COPYING, included with this Distribution. # Normal command to build LFT: # make -f Makefile. # refers to the *standard* compiler/OS on the given system. # # bsd generic BSD 4.3 # solaris GCC Solaris # linux generic Linux # darwin darwin - Mac OS X # Directory where LFT will be installed: prefix=@prefix@ exec_prefix=@exec_prefix@ bindir=@bindir@ mandir=@mandir@ INSTALL=@INSTALL@ LN=@LN_S@ # Commands/References CC=@CC@ CFLAGS=@CFLAGS@ LIBS=@LIBS@ LDFLAGS=@LDFLAGS@ CAT=cat CD=cd MKDIR=mkdir -p BUILDTYPE=build RM=rm -rf SH=sh SYSTEM=unix TOOLS=tools TOUCH=touch @SET_MAKE@ # Specifics OBJS=lft.o lft_ifname.o whois.o all: lft lft: $(OBJS) $(CC) -o lft $(OBJS) $(LDFLAGS) $(LIBS) -lm whois-test: whois.o $(CC) -o whois-test whois.c -DSTANDALONE $(LDFLAGS) $(LIBS) -lm install: lft lft.8 test -d $(bindir)/. || $(MKDIR) $(bindir) $(INSTALL) lft $(bindir)/lft @ ( echo chown root $(bindir)/lft && chown root $(bindir)/lft && echo chmod u+s $(bindir)/lft && chmod u+s $(bindir)/lft ) || echo "***" WARNING: could not set $(bindir) suid to root test -d $(mandir)/man8/. || $(MKDIR) $(mandir)/man8 $(INSTALL) lft.8 $(mandir)/man8/lft.8 clean: $(RM) *.o core* lft *~ distclean: $(RM) Makefile acconfig.h config.log config.status lft-2.2/README0100664000077400007740000000062407631727551011552 0ustar nilsnils # This file is part of LFT. # # The LFT software provided in this Distribution is # Copyright 2003 MainNerve, Inc. # # The full text of our legal notices is contained in the file called # COPYING, included with this Distribution.

LFT  

NAME

lft - display the route packets take to a network host/socket; optionally show heuristic network information in transitu  

SYNOPSIS

lft [-d dport ] [-s sport ] [-m min ] [-M max ] [-a ahead ] [-c scatter ms ] [-t timeout ms ] [-l min ttl ] [-q ISN ] -words [-D device ] [-H ttl ] [-i ] [-n ] [-E ] [-N ] [-A ] [-T ] [-S ] [-V ] [-v ] [<gateway> <...>] host:dport  

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))

lft sends various TCP SYN and FIN probes (differing from Van Jacobson's UDP-based method) utilizing the IP protocol `time to live' field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to some host. lft also listens for various TCP and ICMP messages along the way to assist network managers in ascertaining per-protocol heuristic routing information and can optionally retrieve various information about the networks it traverses.

The only mandatory parameter is the destination host name or IP number. Options toggle the display of more interesting data or change the variables of the trace itself. The (-E) "smart" option tries several combinations in order to improve the chance of a successful trace.

Other options are:

-d dport
Set 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.
-s sport
Set 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.
-m min
Set min as the minimum number of probes to send per host. Default is 1 unless "smart" (-E) mode is used.
-M max
Set max as the maximum number of probes to send per host. Default is 5.
-a ahead
Set ahead as the number of hops forward to query before waiting for a response. Default is 5.
-c scatter ms
Set scatter ms as the minimum number of milliseconds to wait between sending probes. Default is 20.
-t timeout ms
Set timeout ms as the maximum number of milliseconds to wait before assuming a probe was lost/discarded. Default is 1000.
-l min ttl
Set 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.
-q ISN
Set ISN as the ISN (initial sequence number) of the first probe. If unset, one will be automatically generated.
-D device
Set device as the network device to be used. (e.g., "en1") If unset, one will be automagically selected by default.
-H ttl
Set ttl as the maximum TTL, essentially the maximum route traversal distance in hops. Default is 30.
-i
Disable "stop" on ICMP other than TTL expired.
-n
Print addresses numerically rather than symbolically and numerically. Disables use of the DNS resolver completely.
-E
Enable use of the "smart" engine which tries FIN/SYN/etc tables to improve the chance of a successful trace. The engine also displays other useful information such as stateful inspection firewalls it finds along the way.
-N
Enable lookup and display of network names (e.g., [GNTY-NETBLK-4]). This option queries various registries of network address allocation such as ARIN.
-A
Enable lookup and display of of AS (autonymous system) numbers (e.g., [1]). This option queries various registries of network address allocation such as ARIN.
-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.
-S
Suppress display of the real-time status bar. This option makes LFT show its completed trace output only, no-frills.
-V
Verbose output. Mostly debug garbage. Likely too verbose for regular use.
-v
Display version information, then exit().

Any hosts listed after these options and before the final host will comprise the loose source route. Since network operators have security concerns with regard to the use of source routing, don't expect the LSRR options to do much for you in most public network environments.  

EXAMPLES

A sample use and output might be:

**   [4.2-3 BSD bug] the next gateway may errantly reply with reused TTLs
21   [target] vnsc-bak.sys.gtei.net (4.2.2.2) 11.2ms

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] 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 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).

Now, using the smart engine option: 


[edge.lax]$ lft -E -S 4.2.2.1

Hop  LFT trace to vnsc-pri.sys.gtei.net (4.2.2.1):80/tcp
