For more info see the README. Dependencies ------------ libnet 1.1.x https://github.com/sam-github/libnet or http://ftp.debian.org/debian/pool/main/libn/libnet/libnet_1.1.2.1.orig.tar.gz Note: Libnet 1.1.5 or later needed for Linux capability support. libpcap: www.tcpdump.org optional: libcap Adds support to drop Linux privileges. For debian, just: apt-get install libpcap-dev libnet1-dev libcap-dev Installing, short version ------------------------- ./configure make # the binary will be created as src/arping make install If your environment is not set up right (hello Solaris), you may need to add stuff to the configure line, like: ./configure LDFLAGS="-L/usr/lib -L/opt/csw/lib -R/opt/csw/lib" Installing, longer version -------------------------- Note that arping 2.x requires libnet 1.1.x to work. It will NOT work with libnet 1.0.x. Arping 1.x works with libnet 1.0.x, but it's not included in the same package anymore. Standard autotools: ./configure && make && make install The autotools build system is new with arping 2.09. If you have problems with it I want to hear about it. Email me at thomas@habets.se and attach the config.log file. If it failed during 'make', give me all the output from that. Examples that I use on some systems: Linux: apt-get install libnet1-dev libpcap-dev ./configure OpenBSD: ./configure CPPFLAGS=-I/usr/local/include/libnet-1.1 \ LDFLAGS=-L/usr/local/lib FreeBSD: pkg_add -r libnet115 # (or similar) pkg_add -r libpcap # (or similar) ./configure CPPFLAGS='-I/usr/local/include/libnet115' \ LDFLAGS='-L/usr/local/lib/libnet115' Solaris: ./configure CPPFLAGS="-I/usr/local/include" \ LDFLAGS="-R/usr/local/lib -L/opt/csw/lib -R/opt/csw/lib" IRIX: ./configure LDFLAGS="-L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib" arping-2.14/LICENSE0000644000175000017500000004310312353762377013307 0ustar thompathompa GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. arping-2.14/Makefile.am0000644000175000017500000000053212353762377014335 0ustar thompathompa# arping/Makefile.am # include $(top_srcdir)/Makefile.am.common SUBDIRS=src doc tarball: ./extra/mktarball latest mrproper: maintainer-clean rm -f aclocal.m4 configure.scan depcomp missing install-sh config.h.in rm -f Makefile.in configure autoscan*.log config.guess config.sub rm -f ltmain.sh configure.in src/Makefile.in doc/Makefile.in arping-2.14/Makefile.am.common0000644000175000017500000000011312353762377015617 0ustar thompathompa# arping/Makefile.am.common AUTOMAKE_OPTIONS = foreign DISTCLEANFILES = *~ arping-2.14/README0000644000175000017500000002605612353762377013172 0ustar thompathompaarping/README ARP Ping By Thomas Habets http://www.habets.pp.se/synscan/ http://github.com/ThomasHabets/arping git clone git://github.com/ThomasHabets/arping.git Introduction ------------ Arping is a util to find out it a specific IP address on the LAN is 'taken' and what MAC address owns it. Sure, you *could* just use 'ping' to find out if it's taken and even if the computer blocks ping (and everything else) you still get an entry in your ARP cache. But what if you aren't on a routable net? Or the host blocks ping (all ICMP even)? Then you're screwed. Or you use arping. Why it's not stupid ------------------- Say you have a block of N real IANA-assigned IP-addresses. You want to debug the net and you don't know which IP addresses are taken. You can't ping anyone before you take the IP, and you can't pick an IP before you know which are already taken. Catch 22. But with arping you can 'ping' the IP and if you get no response, the IP is available. Example uses ------------ If some box is dumping non-IP (like IPX) garbage and you don't know which box it is, you can ping by MAC to get the IP and fix the problem. If you are on someone else's net and want to 'borrow' a real IP address instead of using one of those 10.x.x.x-addresses the DHCP hands out you probably want to know which ones are taken, or people will get mad (a friend of mine got a call on his cellphone about 15 seconds after he accidentally 'stole' an IP, oops). Compiling / installing ---------------------- See INSTALL file. I try to test arping on these platforms before any release: * Latest Debian stable x86 and amd64 * Linux (Debian or Ubuntu) on arm * Latest OpenBSD x86 or amd64 * FreeBSD x86 * Solaris 10 sparc I don't have these systems up and runnig 24/7, but I try to get them tested every now and then: * MacOS X * Debian alpha * OpenBSD sparc64 (last test: 2009-10-02) * IRIX 6.5 mips (last test 2009-09-27) Mailing list ------------ Check out http://www.habets.pp.se/synscan/mailinglists.php for information on how to subscribe to help- and announce-lists. How it does it -------------- See 'Technical' at the bottom of this file. FAQ --- Q: Where is Arping 1.x? I use libnet 1.0.x so I need that! A: Arping 1 has finally been removed from the Arping 2.x tarball in 2.09. Arping 1.x currently only lives in the Arping packages 2.08 and lower. If features are to be added or bugs fixed it will show up again as a separate package forked from Arping 2.08. For now just get arping-2.08.tar.gz and use that. --- Q: Where's the Windows version? A compiled .exe would be nice. A: I don't have a windows box, so the .exe I'm providing was NOT compiled by me. If something is strange about it tell me, but there won't be much I can do about it. That being said: http://www.habets.pp.se/synscan/files/arping-for-windows-not-compiled-by-me.exe --- Q: After compiling arping without any problem, i test it first with localhost... but it doesn't respond. Isn't that strange? A: Not really, as you can see by typing 'ifconfig' the lo (local) interface does not have a MAC address. It's not a physical device! MAC addresses are there to differentiate computers on a shared medium (the aether, or ether) and since packets to localhost does not go over any wire there is no need to identify which box is talking to which. There is only one. --- Q: Arping can't ping anything! A: Check which interface is active with -v. If it's the wrong one, use -i to set it right. --- Q: Arping finds some hosts, but not others. why? BTW, I have several NICs. A: You have to choose interface with the -i switch if the default is wrong for you. --- Q: I tried to ping my own MAC address, but it doesn't work. A: A sane OS will think it's suspicious if you send packets to yourself over the wire and will ignore them. And why would you want to lookup the IP or MAC of yourself? ifconfig can tell you that. --- Q: I can't ping any/some MAC address on my LAN. A: Arping when pinging a MAC relies on the host to answer a broadcast ping (icmp echo request) properly (IIRC: not the windows way). If you want a host to pop up on MAC ping, you have to config it to respond to broadcast pings. (for linux, make sure /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts is 0) A: -T allows you to restrict the arping to a limited subnet, which may or may not work for you. For example if the box 00:01:02:03:04:05 is on 192.168.0.0/24 then the broadcast probably is 192.168.0.255, so try: # arping -T 192.168.0.255 00:01:02:03:04:05 --- Q: ./configure says I need libnet and/or libpcap A: Arping depends on libnet 1.1.x and libpcap, get libnet at: http://www.packetfactory.net/libnet and libpcap from http://www.tcpdump.org. Lately www.packetfactory.net seems to be down, so you can get the original tarball from the Debian archives: http://ftp.debian.org/debian/pool/main/libn/libnet/libnet_1.1.4.orig.tar.gz If that exact file doesn't exist there probably is one with a higher version number. Or github.com: http://github.com/sam-github/libnet http://github.com/ThomasHabets/libnet --- Q: I get bus error on my non-x86 box A: Damn, I thought I fixed those. Tell me how you got it and I'll try to fix it. Attaching config.log always helps. --- Q: I get "libnet_get_ipaddr(): no error" when I run arping with IP (src or dst) 255.255.255.255. A: Use the -b/-B switches. Libnet sucks (ha ha only serious) and returns -1 for error == int32 encoded 255.255.255.255. --- Q: I used to be able to use -S 255.255.255.255, now it fails. What's going on? Q: Why can't I arping 255.255.255.255? A: Argh! Why would you want to? Anyway, this one is due to libnets resolving, and my unwillingness to reimplement it (in a portable manner, ugh). -S 255.255.255.255 can be replaced with -b, and pinging broadcast (why you would do that eludes me) -B. To be extra perverted, try: # ./arping -b -B (yes, I added -b and -B just so that version 1.0 should be complete) --- Q: 1.01 is out, didn't you just say 1.0 was supposed to be the last one? A: Shut up. --- Q: The roundtrip times are off, sometimes by milliseconds! A: I know. Short answer: 'ping' does the same thing. (ping from iputils-ss010824 anyway) Long answer: I can't (portably anyway) do anything other than queue a packet to the network. That means I don't know exactly when it arrived. Also, I can't tell when a packet arrives on the wire, only when arping gets it from the kernel. Just make sure neither the network (whole segment if you are hubbed, just your NIC if you are switched) nor your box is loaded when you care about timing, and/or run arping with higher priority. # nice -n -15 arping foobar But if you find way to get more exact timing portably (or just for one OS really), let me know. --- Q: Is it OK to make arping suid root? A: Be my guest, but if care about security *at all* you will have to restrict execution of arping to trusted users. I could remove "dangerous" features from the code when it's running suid, but I honestly don't want to. This is a network debugging tool, which generates low-level network packets that ordinary users have absolutely no business generating. If you are honestly debugging the network then I don't see why you aren't root already. That being said, on Linux you can add the CAP_NET_RAW capability to arping limiting the damage if arping were to be compromised: sudo setcap cap_net_raw+ep /usr/local/sbin/arping This requires a libnet 1.1.5 or higher, which does not explicitly check for uid 0. For older versions of Libnet: http://github.com/ThomasHabets/libnet/commit/aaa383b5c816107082508b7646929a9479b81645 --- Q: What's this -A switch all about, I don't understand it. A: Normally arping packets are sent out to some kind of broadcast (MAC or IPv4 broadcast) and hosts reply with source address == their address. If -A is given, only packets coming in with a *source* address equal to the *destination* address in the query is accepted. If you don't understand, don't worry. You won't need it. But for an example use, see the arping-scan-net.sh script. --- License ------- It's GPLv2, see the LICENSE file. Technical --------- Yes, I've finally bothered to write how it works. tcpdumps were taken with "tcpdump -vven 'arp or icmp'". The source box is 192.168.0.2/0:10:5a:3e:c5:b4 and the target box is 192.168.0.1/0:60:93:34:91:99. For pinging IP addresses: When a host wants to send an IP packet to another host, it sends out an ARP packet asking what MAC the destination IP address has, a so-called 'who-has' packet. This is then answered by another ARP packet, the 'is-at' packet. 18:16:07.179699 0:10:5a:3e:c5:b4 ff:ff:ff:ff:ff:ff 0806 42: arp who-has 192.168.0.1 tell 192.168.0.2 This is the packet generated by arping. An Ethernet frame from my 3com card to the broadcast address carrying an arp packet asking what MAC 192.168.0.1 has (who-has). 18:16:07.180221 0:60:93:34:91:99 0:10:5a:3e:c5:b4 0806 60: arp reply 192.168.0.1 is-at 0:60:93:34:91:99 The answer, that 192.168.0.1 has MAC 0:60:93:34:91:99 (is-at). For pinging MAC addresses: A broadcast ping (255.255.255.255, or any address supplied with -T, see below) is sent out on the Ethernet, but in an Ethernet frame addressed to the target MAC only. 18:20:09.627321 0:10:5a:3e:c5:b4 0:60:93:34:91:99 0800 42: 192.168.0.2 > 255.255.255.255: icmp: echo request (ttl 48, id 17767, len 28) This is the packet generated by arping. Ethernet frame from my 3com NIC to the destination MAC, carrying a broadcast ping. 18:20:09.628432 0:60:93:34:91:99 0:10:5a:3e:c5:b4 0800 60: 192.168.0.1 > 192.168.0.2: icmp: echo reply (ttl 255, id 7593, len 28) The answer, including the source address of the target host. Note that this is not how every OS responds to a broadcast ping (if at all). Some answer with a source address equal to the broadcast address, and others don't' answer at all. This is why pinging a raw MAC doesn't always work, and you may need to play with -T to get it to answer correctly (or at all). You can always brute-force if you can't even find a broadcast that the box will answer correctly to. ------- for d in $(seq 0 255); do sudo arping -q -c 1 -T $a.$b.$c.$d 0:60:93:34:91:99 if [ $? = 0 ]; then echo "Got answer with address: 192.168.0.$d" fi done -------- Note that this script will take 1 second per IP since that is how long arping waits, so scanning a C-class net will take 256 seconds. If you have a bigger net, then write a program that will run several arpings at the same time to go through more in less time, or check out arping-scan-net.sh, which is a more capable script for scanning, but you need to edit it since the address range it searches is hard-coded. I may add this to arping some day, but don't hold your breath. ----------------------------------------------------------------------- Send questions/suggestions/patches/rants/money/envy to thomas@habets.se arping-2.14/bootstrap.sh0000755000175000017500000000003012353762377014646 0ustar thompathompa#!/bin/sh autoreconf -i arping-2.14/configure.ac0000644000175000017500000000602612353762377014573 0ustar thompathompa# -*- Autoconf -*- # Process this file with autoconf to produce a configure script.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.
