The configure script will determine +your system attributes and generate an appropriate Makefile from +Makefile.in. Next run "make". If everything goes well you can su to +root and run "make install" and "make install-man". Note that traceroute +must be installed setuid to root or run as root. + +If configure fails for some reason and decide to submit a bug report to +traceroute@ee.lbl.gov, please include a copy of config.log. + +You will need an ANSI C compiler to build libpcap. The configure script +will abort if your compiler is not ANSI compliant. If this happens, use +the GNU C compiler, available via anonymous ftp: + + ftp://prep.ai.mit.edu/pub/gnu/gcc-*.tar.gz + +KERNEL MODIFICATIONS +-------------------- +If yor have a really old system, it may be necessary to modify your +kernel before traceroute will work. If you want to hack on your kernel, +a modified version of the routine rip_output (normally found in the +file /sys/netinet/raw_ip.c) can be found in rip_output.c. This code may +or may not resemble the code in your kernel. It may offer you a place +to start but we 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. We wish you the best of luck +and you're on your own. + +Some older kernels forward icmp packets that have a ttl of zero. If +your system has this bug, 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., SunOS 3) 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 & SunOS 3 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). + + +FILES +----- +CHANGES - description of differences between releases +FILES - list of files exported as part of the distribution +INSTALL - this file +Makefile.in - compilation rules (input to the configure script) +README - description of distribution +VERSION - version of this release +acsite.m4 - autoconf macros +config.guess - autoconf support +config.sub - autoconf support +configure - configure script (run this first) +configure.in - configure script source +install-sh - BSD style install script +lbl/gnuc.h - gcc macros and defines +lbl/os-*.h - os dependent defines and prototypes +mean.awk - awk script to print out the mean time along a route +median.awk - awk script to print out the median time along a route +mkdep - construct Makefile dependency list +rip_output.c - sample rip_output() from /sys/netinet/raw_ip.c +traceroute.8 - manual entry +traceroute.c - main program +strerror.c - emulation routine diff --git a/contrib/traceroute/Makefile.in b/contrib/traceroute/Makefile.in new file mode 100644 index 000000000000..3320abfb0f6c --- /dev/null +++ b/contrib/traceroute/Makefile.in @@ -0,0 +1,126 @@ +# Copyright (c) 1988, 1989, 1990, 1991, 1992, 1995, 1996 +# The Regents of the University of California.

The default is 30 hops (the same default used for TCP +connections). +.TP +.B \-n +Print hop addresses numerically rather than symbolically and numerically +(saves a nameserver address-to-name lookup for each gateway found on the +path). +.TP +.B \-p +Set the base UDP port number used in probes (default is 33434). +Traceroute hopes that nothing is listening on UDP ports +.I base +to +.I base + nhops - 1 +at the destination host (so an ICMP PORT_UNREACHABLE message will +be returned to terminate the route tracing). If something is +listening on a port in the default range, this option can be used +to pick an unused port range. +.TP +.B \-r +Bypass the normal routing tables and send directly to a host on an attached +network. +If the host is not on a directly-attached network, +an error is returned. +This option can be used to ping a local host through an interface +that has no route through it (e.g., after the interface was dropped by +.IR routed (8C)). +.TP +.B \-s +Use the following IP address (which must be given as an IP number, not +a hostname) as the source address in outgoing probe packets. On +hosts with more than one IP address, this option can be used to +force the source address to be something other than the IP address +of the interface the probe packet is sent on. If the IP address +is not one of this machine's interface addresses, an error is +returned and nothing is sent. +.TP +.B \-t +Set the +.I type-of-service +in probe packets to the following value (default zero). The value must be +a decimal integer in the range 0 to 255. This option can be used to +see if different types-of-service result in different paths. (If you +are not running 4.4bsd, this may be academic since the normal network +services like telnet and ftp don't let you control the TOS). +Not all values of TOS are legal or +meaningful \- see the IP spec for definitions. Useful values are +probably `-t 16' (low delay) and `-t 8' (high throughput). +.TP +.B \-v +Verbose output. Received ICMP packets other than TIME_EXCEEDED and +UNREACHABLEs are listed. +.TP +.B \-w +Set the time (in seconds) to wait for a response to a probe (default 5 +sec.). +.PP +This program attempts to trace the route an IP packet would follow to some +internet host by launching UDP probe +packets with a small ttl (time to live) then listening for an +ICMP "time exceeded" reply from a gateway. We start our probes +with a ttl of one and increase by one until we get an ICMP "port +unreachable" (which means we got to "host") or hit a max (which +defaults to 30 hops & can be changed with the \-m flag). Three +probes (change with \-q flag) are sent at each ttl setting and a +line is printed showing the ttl, address of the gateway and +round trip time of each probe. If the probe answers come from +different gateways, the address of each responding system will +be printed. If there is no response within a 5 sec. timeout +interval (changed with the \-w flag), a "*" is printed for that +probe. +.PP +We don't want the destination +host to process the UDP probe packets so the destination port is set to an +unlikely value (if some clod on the destination is using that +value, it can be changed with the \-p flag). +.PP +A sample use and output might be: + +.RS +.nf +[yak 71]% traceroute nis.nsf.net. +traceroute to nis.nsf.net (35.1.1.48), 30 hops max, 38 byte packet + 1 helios.ee.lbl.gov (128.3.112.1) 19 ms 19 ms 0 ms + 2 lilac-dmc.Berkeley.EDU (128.32.216.1) 39 ms 39 ms 19 ms + 3 lilac-dmc.Berkeley.EDU (128.32.216.1) 39 ms 39 ms 19 ms + 4 ccngw-ner-cc.Berkeley.EDU (128.32.136.23) 39 ms 40 ms 39 ms + 5 ccn-nerif22.Berkeley.EDU (128.32.168.22) 39 ms 39 ms 39 ms + 6 128.32.197.4 (128.32.197.4) 40 ms 59 ms 59 ms + 7 131.119.2.5 (131.119.2.5) 59 ms 59 ms 59 ms + 8 129.140.70.13 (129.140.70.13) 99 ms 99 ms 80 ms + 9 129.140.71.6 (129.140.71.6) 139 ms 239 ms 319 ms +10 129.140.81.7 (129.140.81.7) 220 ms 199 ms 199 ms +11 nic.merit.edu (35.1.1.48) 239 ms 239 ms 239 ms +.fi +.RE + +Note that lines 2 & 3 are the same.

So, the reply will time out on the return path +(with no notice sent to anyone since ICMP's aren't sent for +ICMP's) until we probe with a ttl that's at least twice the path +length. I.e., rip is really only 7 hops away. A reply that +returns with a ttl of 1 is a clue this problem exists. +Traceroute prints a "!" after the time if the ttl is <= 1. +Since vendors ship a lot of obsolete (DEC's Ultrix, Sun 3.x) or +non-standard (HPUX) software, expect to see this problem +frequently and/or take care picking the target host of your +probes. + +Other possible annotations after the time are +.BR !H , +.BR !N , +or +.B !P +(got a host, network or protocol unreachable, respectively), +.B !S +or +.B !F +(source route failed or fragmentation needed \- neither of these should +ever occur and the associated gateway is busted if you see one), +.B !X +(communication administratively prohibited), or +.B !<N> +(ICMP unreachable code N). +If almost all the probes result in some kind of unreachable, traceroute +will give up and exit. +.PP +This program is intended for use in network testing, measurement +and management. +It should be used primarily for manual fault isolation. +Because of the load it could impose on the network, it is unwise to use +.I traceroute +during normal operations or from automated scripts. +.SH SEE ALSO +netstat(1), ping(8) +.SH AUTHOR +Implemented by Van Jacobson from a suggestion by Steve Deering.

So, the reply will time out on the return path + * (with no notice sent to anyone since icmp's aren't sent for + * icmp's) until we probe with a ttl that's at least twice the path + * length. I.e., rip is really only 7 hops away.

If + * almost all the probes result in some kind of unreachable, traceroute + * will give up and exit. + * + * Notes + * ----- + * This program must be run by root or be setuid. (I suggest that + * you *don't* make it setuid -- casual use could result in a lot + * of unnecessary traffic on our poor, congested nets.) + * + * This program requires a kernel mod that does not appear in any + * system available from Berkeley: A raw ip socket using proto + * IPPROTO_RAW must interpret the data sent as an ip datagram (as + * opposed to data to be wrapped in a ip datagram). See the README + * file that came with the source to this program for a description + * of the mods I made to /sys/netinet/raw_ip.c. Your mileage may + * vary. But, again, ANY 4.x (x < 4) BSD KERNEL WILL HAVE TO BE + * MODIFIED TO RUN THIS PROGRAM. + * + * The udp port usage may appear bizarre (well, ok, it is bizarre). + * The problem is that an icmp message only contains 8 bytes of + * data from the original datagram. 8 bytes is the size of a udp + * header so, if we want to associate replies with the original + * datagram, the necessary information must be encoded into the + * udp header (the ip id could be used but there's no way to + * interlock with the kernel's assignment of ip id's and, anyway, + * it would have taken a lot more kernel hacking to allow this + * code to set the ip id). So, to allow two or more users to + * use traceroute simultaneously, we use this task's pid as the + * source port (the high bit is set to move the port number out + * of the "likely" range). To keep track of which probe is being + * replied to (so times and/or hop counts don't get confused by a + * reply that was delayed in transit), we increment the destination + * port number before each probe. + * + * Don't use this as a coding example. I was trying to find a + * routing problem and this code sort-of popped out after 48 hours + * without sleep. I was amazed it ever compiled, much less ran. + * + * I stole the idea for this program from Steve Deering. Since + * the first release, I've learned that had I attended the right + * IETF working group meetings, I also could have stolen it from Guy + * Almes or Matt Mathis. I don't know (or care) who came up with + * the idea first. I envy the originators' perspicacity and I'm + * glad they didn't keep the idea a secret. + * + * Tim Seaver, Ken Adelman and C. Philip Wood provided bug fixes and/or + * enhancements to the original distribution. + * + * I've hacked up a round-trip-route version of this that works by + * sending a loose-source-routed udp datagram through the destination + * back to yourself. Unfortunately, SO many gateways botch source + * routing, the thing is almost worthless.
