- This README file outlines what each file in this collection is.

-
- Traceroute is a utility written by Van Jacobson that traces the exact
- network route that packets take while being routed from your machine
- to any specified remote host. This is an extremely useful debugging
- tool for network managers.
-
- This collection of files is my attempt to put together in one easy
- place all the files and info needed to enable traceroute on a Sun 3,
- 3x, or 4 machine running SunOS 4.0.x. This collection includes the
- following:
-
- -- Source code for three kernel files (raw_ip.c, ip_icmp.c, and
- ip_icmp.h) on which the necessary kernel modifications have been
- performed. These files came from Bill Nowicki of Sun
- <nowicki@sun.com>, who made the actual modifications. They are the
- definitive version of these files for Sun 3, 3x, and 4 machines,
- and I can vouch that they work. (I don't have any 386i machines,
- so I can't vouch for whether these files will work on a 386i or
- not.)
-
- -- A traceroute.c file that has been patched with Matt Mathis'
- <mathis@fornax.ece.cmu.edu> modifications for supporting IP LSRR
- (Loose Source Record Route). This allows you to find out how
- somebody else (at a site other than your own machine, that is)
- would reach a particular target.
-
- -- A man page for traceroute that includes a description of the IP
- LSRR feature. From Paul Pomes <paul@uxc.cso.uiuc.edu>.
-
- -- A Makefile that will help automate the installation of the necessary
- binaries. From Manavendra K. Thakur <thakur@zerkalo.harvard.edu>.
-
- My thanks to Robert M. Enger <enger@sccgate.scc.com> and Edward
- Vielmetti <emv@math.lsa.umich.edu> for forwarding to me the bulk of
- the pieces that comprise this collection.
-
-
- Here is a summary of all the files and subdirectories:
-
- README This file -- For more info on this collection
- of files, please contact Manavendra K. Thakur
- <thakur@zerkalo.harvard.edu>. For more info on
- the traceroute code,itself, please contact the
- appropriate authors.
-
- Makefile Makefile to compile and install ip_icmp.o,
- raw_ip.o, and traceroute. Note that you still
- have to recompile and reinstall your kernel
- after running the Makefile.
-
- ip_icmp.c, ip_icmp.h Source code for the kernel modules that need
- raw_ip.c recompiling in order to run traceroute. From
- Bill Nowicki of Sun Microsystems <nowicki@sun.com>.
-
- traceroute.c Source code for the actual traceroute executable.
- From Van Jacobson <van@helios.ee.lbl.gov> and
- Matt Mathis <mathis@fornvax.ece.cmu.edu>.
-
- traceroute.8 Man page for traceroute. Includes documentation
- of the IP LSRR feature. From Paul Pomes
- <paul@uxc.cso.uiuc.edu>.
-
- vj_traceroute Directory with original traceroute code from
- Van Jacobson. This directory comes from the
- traceroute.tar.Z file on ftp.ee.lbl.gov. If you
- should want to create the source code and binaries
- from scratch for any reason, you should begin
- with these files. If you want the Loose
- Source Record Route option, then apply the
- patches contained in LSRR.patches file in the
- vj_traceroute directory. Consult the README and
- LSRR.patches files in the vj_traceroute directory
- for more information.
-
- vj_traceroute/LSRR.patches
- Matt Mathis' patches to Van Jacobson's traceroute.
- These patches enable LSRR (source level routing).
-
- bin This directory contains pre-compiled versions of all
- the binaries that would be created by running the
- Makefile, for both Sun 3 and Sun 4 machines. (The
- Sun 3 binaries will also work on a Sun 3x machine.)
- See the README file in the bin directory for more
- information.
