|
||||
|
||||
v1.4 Fri Jun 13 02:23:51 PDT 1997
|
||||
|
||||
- Add an option to use icmp echo instead of udp datagrams.
|
||||
|
||||
- Add HPUX and Linux support.
|
||||
|
||||
- Handle hex argument values as suggested by John Hawkinson
|
||||
(jhawk@mit.edu)
|
||||
|
||||
- Added flags to set the first ttl and to set the don't fragment bit.
|
||||
|
||||
- Removed dependence on strdup().
|
||||
|
||||
- Add a local autoconf macro to check for routines in libraries; the
|
||||
autoconf version is broken (it only puts the library name in the
|
||||
cache variable name). Thanks to John Hawkinson.
|
||||
|
||||
- Add a local autoconf macro to check for types; the autoconf version
|
||||
is broken (it uses grep instead of actually compiling a code fragment).
|
||||
|
||||
v1.3.2 Thu Sep 26 18:06:16 PDT 1996
|
||||
|
||||
- Rewrite source routing code to eliminate a number of problems on
|
||||
systems using raw ip options. Also pad options with a noop so gateway
|
||||
addresses are aligned.
|
||||
|
||||
- Don't call inet_ntoa() twice in the same printf(). Thanks to NetBSD
|
||||
via Bill Fenner (fenner@parc.xerox.com)
|
||||
|
||||
- Decode "administratively prohibited filter" icmp code and print
|
||||
numeric value for unknown codes. Thanks to Bill Fenner.
|
||||
|
||||
v1.3.1 Wed Sep 18 21:08:16 PDT 1996
|
||||
|
||||
- Some systems (e.g. AIX) need sys/select.h. Thanks to Brett Hogden
|
||||
(hogden@rge.com)
|
||||
|
||||
- Byte swap ip header length under Solaris. (This has no effect on the
|
||||
sparc but is required on the i386.)
|
||||
|
||||
- Made optional packet length control total size of packet.
|
||||
|
||||
v1.3 Mon Sep 16 14:55:44 PDT 1996
|
||||
|
||||
- Overrun buffer security fixes. Thanks to Bill Fenner
|
||||
(fenner@parc.xerox.com)
|
||||
|
||||
- Wait for response packet relative to start of probe. Thanks to Bill
|
||||
Fenner.
|
||||
|
||||
- Fix bug that prevented changing the packet size. Thanks to Gregory
|
||||
Decker (gdecker@nate.dcrt.nih.gov)
|
||||
|
||||
- Add support for RAW_OPTIONS (e.g. 4.4 BSD systems such as BSD/OS and
|
||||
FreeBSD) thanks to Jeffrey C Honig (jch@bsdi.com)
|
||||
|
||||
- Remove ip header byte swap fix from v1.2; most kernels swap the ip
|
||||
header length in the kernel (and it causes OSF3 to crash).
|
||||
|
||||
- Fix to not exit when the number of probes is set to 1 (i.e. "-q 1")
|
||||
|
||||
- Improve autoconf configuration.
|
||||
|
||||
v1.2 Tue Oct 17 23:50:05 PDT 1995
|
||||
|
||||
- Convert to autoconf and ansify.
|
||||
|
||||
- Byte swap ip header length for little endian machines. Fix thanks to
|
||||
Y Badri (yb@greybox.demon.co.uk).
|
||||
|
||||
v1.1 Thu Jun 15 02:32:55 PDT 1995
|
||||
|
||||
- Check for too many arguments.
|
||||
|
||||
- Recode to make timing of packet's round trip more obvious and to
|
||||
tighten up code.
|
||||
|
||||
- Ifdef IP_OPTIONS code.
|
||||
|
||||
- Display time in microseconds.
|
||||
|
||||
v1.0 Tue Feb 28 23:50:05 PDT 1989
|
||||
|
||||
- Initial public release.

TRACEROUTE 1.4
|
||||
Lawrence Berkeley National Laboratory

||||

||||
ftp://ftp.ee.lbl.gov/traceroute.tar.Z
|
||||
|
||||
Traceroute is a system administrators utility to trace the route
|
||||
ip packets from the current system take in getting to some
|
||||
destination system. See the comments at the front of the
|
||||
program for a description of its use.
|
||||
|
||||
This program
|
||||
|
||||
a) can only be run by root (it uses raw ip sockets).
|
||||
|
||||
b) REQUIRES A KERNEL MOD to the raw ip output code to run.
|
||||
|
||||
If you want to hack on your kernel, my modified version of the
|
||||
routine rip_output (in file /sys/netinet/raw_ip.c) is attached.
|
||||
This code may or may not resemble the code in your kernel.
|
||||
It may offer you a place to start but I make no promises.
|
||||
If you do hack your kernel, remember to test everything that uses
|
||||
raw ip sockets (e.g., ping and egpup/gated) & make sure they still
|
||||
work. I wish you the best of luck and you're on your own.
|
||||
|
||||
If your system has the ttl bug mentioned in the source, you
|
||||
might want to fix it while you're in the kernel. (This bug
|
||||
appears in all releases of BSD up to but not including 4.3tahoe.
|
||||
If your version of netinet/ip_icmp.c is any earlier than 7.3
|
||||
(April, '87), it has the bug.) The fix is just to add the line
|
||||
ip->ip_ttl = MAXTTL;
|
||||
after the line
|
||||
ip->ip_src = t;
|
||||
(or anywhere before the call to icmp_send) in routine icmp_reflect.
|
||||
|
||||
If you're running this on a pre-4.3bsd system (e.g., Sun 3.x,
|
||||
Ultrix) that strips ip headers from icmp messages, add -DARCHAIC
|
||||
to CFLAGS in the Makefile. Also note that rip_output contains
|
||||
a conditional for a 4.2/4.3 change in the location of a raw
|
||||
socket's protocol number. I've checked this under 4.3 & Sun OS
|
||||
3.5 but you should double-check your system to make sure the
|
||||
appropriate branch of the #if is taken (check the line that
|
||||
assigned to ip->ip_p in your system's original rip_output).
|
||||
This program uses raw ip sockets and must be run as root (or installed
|
||||
setuid to root).
|
||||
|
||||
A couple of awk programs to massage the traceroute output are
|
||||
included. "mean.awk" and "median.awk" compute the mean and median
|
||||
time to each hop, respectively. I've found that something like
|
||||
included. "mean.awk" and "median.awk" compute the mean and median time
|
||||
to each hop, respectively. I've found that something like
|
||||
|
||||
traceroute -q 7 foo.somewhere >t
|
||||
awk -f median.awk t | graph
|
||||
traceroute -q 7 foo.somewhere >t
|
||||
awk -f median.awk t | xgraph
|
||||
|
||||
can give you a quick picture of the bad spots on a long
|
||||
path (median is usually a better noise filter than mean).
