  3 | 
  4 |  Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
  5 |  51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
  6 |  Everyone is permitted to copy and distribute verbatim copies
  7 |  of this license document, but changing it is not allowed.
  8 | 
  9 | 			    Preamble
 10 | 
 11 |   The licenses for most software are designed to take away your
 12 | freedom to share and change it.  By contrast, the GNU General Public
 13 | License is intended to guarantee your freedom to share and change free
 14 | software--to make sure the software is free for all its users.  This
 15 | General Public License applies to most of the Free Software
 16 | Foundation's software and to any other program whose authors commit to
 17 | using it.  (Some other Free Software Foundation software is covered by
 18 | the GNU Lesser General Public License instead.)  You can apply it to
 19 | your programs, too.
 20 | 
 21 |   When we speak of free software, we are referring to freedom, not
 22 | price.  Our General Public Licenses are designed to make sure that you
 23 | have the freedom to distribute copies of free software (and charge for
 24 | this service if you wish), that you receive source code or can get it
 25 | if you want it, that you can change the software or use pieces of it
 26 | in new free programs; and that you know you can do these things.
 27 | 
 28 |   To protect your rights, we need to make restrictions that forbid
 29 | anyone to deny you these rights or to ask you to surrender the rights.
 30 | These restrictions translate to certain responsibilities for you if you
 31 | distribute copies of the software, or if you modify it.
 32 | 
 33 |   For example, if you distribute copies of such a program, whether
 34 | gratis or for a fee, you must give the recipients all the rights that
 35 | you have.  You must make sure that they, too, receive or can get the
 36 | source code.  And you must show them these terms so they know their
 37 | rights.
 38 | 
 39 |   We protect your rights with two steps: (1) copyright the software, and
 40 | (2) offer you this license which gives you legal permission to copy,
 41 | distribute and/or modify the software.
 42 | 
 43 |   Also, for each author's protection and ours, we want to make certain
 44 | that everyone understands that there is no warranty for this free
 45 | software.  If the software is modified by someone else and passed on, we
 46 | want its recipients to know that what they have is not the original, so
 47 | that any problems introduced by others will not reflect on the original
 48 | authors' reputations.
 49 | 
 50 |   Finally, any free program is threatened constantly by software
 51 | patents.  We wish to avoid the danger that redistributors of a free
 52 | program will individually obtain patent licenses, in effect making the
 53 | program proprietary.  To prevent this, we have made it clear that any
 54 | patent must be licensed for everyone's free use or not licensed at all.
 55 | 
 56 |   The precise terms and conditions for copying, distribution and
 57 | modification follow.
 58 | 
 59 | 		    GNU GENERAL PUBLIC LICENSE
 60 |    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 61 | 
 62 |   0. This License applies to any program or other work which contains
 63 | a notice placed by the copyright holder saying it may be distributed
 64 | under the terms of this General Public License.  The "Program", below,
 65 | refers to any such program or work, and a "work based on the Program"
 66 | means either the Program or any derivative work under copyright law:
 67 | that is to say, a work containing the Program or a portion of it,
 68 | either verbatim or with modifications and/or translated into another
 69 | language.  (Hereinafter, translation is included without limitation in
 70 | the term "modification".)  Each licensee is addressed as "you".
 71 | 
 72 | Activities other than copying, distribution and modification are not
 73 | covered by this License; they are outside its scope.  The act of
 74 | running the Program is not restricted, and the output from the Program
 75 | is covered only if its contents constitute a work based on the
 76 | Program (independent of having been made by running the Program).
 77 | Whether that is true depends on what the Program does.
 78 | 
 79 |   1. You may copy and distribute verbatim copies of the Program's
 80 | source code as you receive it, in any medium, provided that you
 81 | conspicuously and appropriately publish on each copy an appropriate
 82 | copyright notice and disclaimer of warranty; keep intact all the
 83 | notices that refer to this License and to the absence of any warranty;
 84 | and give any other recipients of the Program a copy of this License
 85 | along with the Program.
 86 | 
 87 | You may charge a fee for the physical act of transferring a copy, and
 88 | you may at your option offer warranty protection in exchange for a fee.
 89 | 
 90 |   2. You may modify your copy or copies of the Program or any portion
 91 | of it, thus forming a work based on the Program, and copy and
 92 | distribute such modifications or work under the terms of Section 1
 93 | above, provided that you also meet all of these conditions:
 94 | 
 95 |     a) You must cause the modified files to carry prominent notices
 96 |     stating that you changed the files and the date of any change.
 97 | 
 98 |     b) You must cause any work that you distribute or publish, that in
 99 |     whole or in part contains or is derived from the Program or any
100 |     part thereof, to be licensed as a whole at no charge to all third
101 |     parties under the terms of this License.
102 | 
103 |     c) If the modified program normally reads commands interactively
104 |     when run, you must cause it, when started running for such
105 |     interactive use in the most ordinary way, to print or display an
106 |     announcement including an appropriate copyright notice and a
107 |     notice that there is no warranty (or else, saying that you provide
108 |     a warranty) and that users may redistribute the program under
109 |     these conditions, and telling the user how to view a copy of this
110 |     License.  (Exception: if the Program itself is interactive but
111 |     does not normally print such an announcement, your work based on
112 |     the Program is not required to print an announcement.)
113 | 
114 | These requirements apply to the modified work as a whole.  If
115 | identifiable sections of that work are not derived from the Program,
116 | and can be reasonably considered independent and separate works in
117 | themselves, then this License, and its terms, do not apply to those
118 | sections when you distribute them as separate works.  But when you
119 | distribute the same sections as part of a whole which is a work based
120 | on the Program, the distribution of the whole must be on the terms of
121 | this License, whose permissions for other licensees extend to the
122 | entire whole, and thus to each and every part regardless of who wrote it.
123 | 
124 | Thus, it is not the intent of this section to claim rights or contest
125 | your rights to work written entirely by you; rather, the intent is to
126 | exercise the right to control the distribution of derivative or
127 | collective works based on the Program.
128 | 
129 | In addition, mere aggregation of another work not based on the Program
130 | with the Program (or with a work based on the Program) on a volume of
131 | a storage or distribution medium does not bring the other work under
132 | the scope of this License.
133 | 
134 |   3. You may copy and distribute the Program (or a work based on it,
135 | under Section 2) in object code or executable form under the terms of
136 | Sections 1 and 2 above provided that you also do one of the following:
137 | 
138 |     a) Accompany it with the complete corresponding machine-readable
139 |     source code, which must be distributed under the terms of Sections
140 |     1 and 2 above on a medium customarily used for software interchange; or,
141 | 
142 |     b) Accompany it with a written offer, valid for at least three
143 |     years, to give any third party, for a charge no more than your
144 |     cost of physically performing source distribution, a complete
145 |     machine-readable copy of the corresponding source code, to be
146 |     distributed under the terms of Sections 1 and 2 above on a medium
147 |     customarily used for software interchange; or,
148 | 
149 |     c) Accompany it with the information you received as to the offer
150 |     to distribute corresponding source code.  (This alternative is
151 |     allowed only for noncommercial distribution and only if you
152 |     received the program in object code or executable form with such
153 |     an offer, in accord with Subsection b above.)
154 | 
155 | The source code for a work means the preferred form of the work for
156 | making modifications to it.  For an executable work, complete source
157 | code means all the source code for all modules it contains, plus any
158 | associated interface definition files, plus the scripts used to
159 | control compilation and installation of the executable.  However, as a
160 | special exception, the source code distributed need not include
161 | anything that is normally distributed (in either source or binary
162 | form) with the major components (compiler, kernel, and so on) of the
163 | operating system on which the executable runs, unless that component
164 | itself accompanies the executable.
165 | 
166 | If distribution of executable or object code is made by offering
167 | access to copy from a designated place, then offering equivalent
168 | access to copy the source code from the same place counts as
169 | distribution of the source code, even though third parties are not
170 | compelled to copy the source along with the object code.
171 | 
172 |   4. You may not copy, modify, sublicense, or distribute the Program
173 | except as expressly provided under this License.  Any attempt
174 | otherwise to copy, modify, sublicense or distribute the Program is
175 | void, and will automatically terminate your rights under this License.
176 | However, parties who have received copies, or rights, from you under
177 | this License will not have their licenses terminated so long as such
178 | parties remain in full compliance.
179 | 
180 |   5. You are not required to accept this License, since you have not
181 | signed it.  However, nothing else grants you permission to modify or
182 | distribute the Program or its derivative works.  These actions are
183 | prohibited by law if you do not accept this License.  Therefore, by
184 | modifying or distributing the Program (or any work based on the
185 | Program), you indicate your acceptance of this License to do so, and
186 | all its terms and conditions for copying, distributing or modifying
187 | the Program or works based on it.
188 | 
189 |   6. Each time you redistribute the Program (or any work based on the
190 | Program), the recipient automatically receives a license from the
191 | original licensor to copy, distribute or modify the Program subject to
192 | these terms and conditions.  You may not impose any further
193 | restrictions on the recipients' exercise of the rights granted herein.
194 | You are not responsible for enforcing compliance by third parties to
195 | this License.
196 | 
197 |   7. If, as a consequence of a court judgment or allegation of patent
198 | infringement or for any other reason (not limited to patent issues),
199 | conditions are imposed on you (whether by court order, agreement or
200 | otherwise) that contradict the conditions of this License, they do not
201 | excuse you from the conditions of this License.  If you cannot
202 | distribute so as to satisfy simultaneously your obligations under this
203 | License and any other pertinent obligations, then as a consequence you
204 | may not distribute the Program at all.  For example, if a patent
205 | license would not permit royalty-free redistribution of the Program by
206 | all those who receive copies directly or indirectly through you, then
207 | the only way you could satisfy both it and this License would be to
208 | refrain entirely from distribution of the Program.
209 | 
210 | If any portion of this section is held invalid or unenforceable under
211 | any particular circumstance, the balance of the section is intended to
212 | apply and the section as a whole is intended to apply in other
213 | circumstances.
214 | 
215 | It is not the purpose of this section to induce you to infringe any
216 | patents or other property right claims or to contest validity of any
217 | such claims; this section has the sole purpose of protecting the
218 | integrity of the free software distribution system, which is
219 | implemented by public license practices.  Many people have made
220 | generous contributions to the wide range of software distributed
221 | through that system in reliance on consistent application of that
222 | system; it is up to the author/donor to decide if he or she is willing
223 | to distribute software through any other system and a licensee cannot
224 | impose that choice.
225 | 
226 | This section is intended to make thoroughly clear what is believed to
227 | be a consequence of the rest of this License.
228 | 
229 |   8. If the distribution and/or use of the Program is restricted in
230 | certain countries either by patents or by copyrighted interfaces, the
231 | original copyright holder who places the Program under this License
232 | may add an explicit geographical distribution limitation excluding
233 | those countries, so that distribution is permitted only in or among
234 | countries not thus excluded.  In such case, this License incorporates
235 | the limitation as if written in the body of this License.
236 | 
237 |   9. The Free Software Foundation may publish revised and/or new versions
238 | of the General Public License from time to time.  Such new versions will
239 | be similar in spirit to the present version, but may differ in detail to
240 | address new problems or concerns.
241 | 
242 | Each version is given a distinguishing version number.  If the Program
243 | specifies a version number of this License which applies to it and "any
244 | later version", you have the option of following the terms and conditions
245 | either of that version or of any later version published by the Free
246 | Software Foundation.  If the Program does not specify a version number of
247 | this License, you may choose any version ever published by the Free Software
248 | Foundation.
249 | 
250 |   10. If you wish to incorporate parts of the Program into other free
251 | programs whose distribution conditions are different, write to the author
252 | to ask for permission.  For software which is copyrighted by the Free
253 | Software Foundation, write to the Free Software Foundation; we sometimes
254 | make exceptions for this.  Our decision will be guided by the two goals
255 | of preserving the free status of all derivatives of our free software and
256 | of promoting the sharing and reuse of software generally.
257 | 
258 | 			    NO WARRANTY
259 | 
260 |   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
262 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
266 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
267 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268 | REPAIR OR CORRECTION.
269 | 
270 |   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278 | POSSIBILITY OF SUCH DAMAGES.
279 | 
280 | 		     END OF TERMS AND CONDITIONS
281 | 
282 | 	    How to Apply These Terms to Your New Programs
283 | 
284 |   If you develop a new program, and you want it to be of the greatest
285 | possible use to the public, the best way to achieve this is to make it
286 | free software which everyone can redistribute and change under these terms.
287 | 
288 |   To do so, attach the following notices to the program.  It is safest
289 | to attach them to the start of each source file to most effectively
290 | convey the exclusion of warranty; and each file should have at least
291 | the "copyright" line and a pointer to where the full notice is found.
292 | 
293 |     <one line to give the program's name and a brief idea of what it does.>
294 |     Copyright (C) <year>  <name of author>
295 | 
296 |     This program is free software; you can redistribute it and/or modify
297 |     it under the terms of the GNU General Public License as published by
298 |     the Free Software Foundation; either version 2 of the License, or
299 |     (at your option) any later version.
300 | 
301 |     This program is distributed in the hope that it will be useful,
302 |     but WITHOUT ANY WARRANTY; without even the implied warranty of
303 |     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
304 |     GNU General Public License for more details.
305 | 
306 |     You should have received a copy of the GNU General Public License along
307 |     with this program; if not, write to the Free Software Foundation, Inc.,
308 |     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
309 | 
310 | Also add information on how to contact you by electronic and paper mail.
311 | 
312 | If the program is interactive, make it output a short notice like this
313 | when it starts in an interactive mode:
314 | 
315 |     Gnomovision version 69, Copyright (C) year name of author
316 |     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317 |     This is free software, and you are welcome to redistribute it
318 |     under certain conditions; type `show c' for details.
319 | 
320 | The hypothetical commands `show w' and `show c' should show the appropriate
321 | parts of the General Public License.  Of course, the commands you use may
322 | be called something other than `show w' and `show c'; they could even be
323 | mouse-clicks or menu items--whatever suits your program.
324 | 
325 | You should also get your employer (if you work as a programmer) or your
326 | school, if any, to sign a "copyright disclaimer" for the program, if
327 | necessary.  Here is a sample; alter the names:
328 | 
329 |   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
330 |   `Gnomovision' (which makes passes at compilers) written by James Hacker.
331 | 
332 |   <signature of Ty Coon>, 1 April 1989
333 |   Ty Coon, President of Vice
334 | 
335 | This General Public License does not permit incorporating your program into
336 | proprietary programs.  If your program is a subroutine library, you may
337 | consider it more useful to permit linking proprietary applications with the
338 | library.  If this is what you want to do, use the GNU Lesser General
339 | Public License instead of this License.

 1 | NDisc6 : IPv6 diagnostic tools
 2 | ===============================
 3 | Copyright © 2005-2006 Rémi Denis-Courmont.
 4 | 
 5 |   This package gathers a few diagnostic tools for IPv6 networks:
 6 | - ndisc6, which performs ICMPv6 Neighbor Discovery in userland,
 7 | - rdisc6, which performs ICMPv6 Router Discovery in userland,
 8 | - rltraceroute6, yet another IPv6 implementation of traceroute,
 9 | - tcptraceroute6, a TCP/IPv6-based traceroute implementation,
10 | - tracert6, a ICMPv6 Echo Request based traceroute,
11 | - tcpspray6, a TCP/IP Discard/Echo bandwidth metter.
12 | 
13 |   For detailled usage instructions, you should refer to the Unix manual
14 | pages ndisc6(8), rdisc6(8), traceroute6(8) and tcpspray6(1) which
15 | should be provided with your copy of the program.
16 |   For instructions on compilation and installation of the package,
17 | refer to the provided INSTALL file.
18 | 
19 |   This package is distributed under the terms of the General Public
20 | License (GPL) version 2 written by the Free Software Foundation, Inc.
21 | for full licensing details, please read COPYING.
22 | 
23 |   If you have further questions, you can contact me via email at:
24 |     reim (at) remlab (dot) net
25 | 
26 |   All programs are known to run on Linux (with either glibc or µclibc).
27 | They should also work on any recent open-source BSD variant, and might
28 | work on Solaris or other BSD derivatives.

19 | .BR "addr2name" " [" "-46cmnr" "] [" "HOSTNAMES" "]"
20 | 
21 | .BR "name2addr" " [" "-46cn" "] [" "HOSTNAMES" "]"
22 | 
23 | .SH DESCRIPTON
24 | Write addresses or canonical hostname of specified names to the standard
25 | output. If no names are specified via the command line, they are read from
26 | the standard input.
27 | 
28 | .SH OPTIONS
29 | 
30 | .TP
31 | .BR "\-4" " or " "\-\-ipv4"
32 | Only try to perform IPv4 lookups.
33 | 
34 | .TP
35 | .BR "\-6" " or " "\-\-ipv6"
36 | Only try to perform IPv6 lookups.
37 | 
38 | .TP
39 | .BR "\-c" " or " "\-\-config"
40 | Only lookup and print results for address families that match locally
41 | configured addresses (If the system has no IPv4 resp IPv6 address,
42 | then IPv4 resp IPv6 addresses are ignored).
43 | 
44 | .TP
45 | .BR "\-h" " or " "\-\-help"
46 | Display some help and exit.
47 | 
48 | .TP
49 | .BR "\-m" " or " "\-\-multiple"
50 | Normally, if a name yields multiple results, only the first one is printed.
51 | With this optional parameter, all results will be printed on a single line,
52 | separated by spaces.
53 | 
54 | .TP
55 | .BR "\-n" " or " "\-\-numeric"
56 | Prevent forward hostname lookup.
57 | This ensures that the input names are numeric addresses, which do not need
58 | to be looked up. Typically used along with the \-\-reverse option to convert
59 | numerical addresses to canonical hostnames.
60 | 
61 | .TP
62 | .BR "\-r" " or " "\-\-reverse"
63 | Perform a reverse DNS lookup
64 | .RB "(enabled implicitly with " "addr2name" ")."
65 | .BR "addr2name" " prints numerical resolved addresses by default instead."
66 | 
67 | .TP
68 | .BR "\-\-version"
69 | Display program version and license and exit.

 22 | .SH DESCRIPTON
 23 | .B NDisc6
 24 | is an Unix program which implements the ICMPv6 Neighbor Discovery in
 25 | userland (it is normally done by the kernel). It is used to lookup the
 26 | link-layer address (layer 2 address, MAC in the case of Ethernet) of
 27 | any on-link IPv6 node.
 28 | 
 29 | The IPv6 address of the node must be specified, as well as the
 30 | networking interface on which to perform the lookup.
 31 | 
 32 | .SH OPTIONS
 33 | 
 34 | .TP
 35 | .BR "\-1" " or " "\-\-single"
 36 | Exit as soon as the first advertisement is received (default).

 45 | 
 46 | .TP
 47 | .BR "\-n" " or " "\-\-numeric"
 48 | If the first parameter is not a valid IPv6 address, do not try to
 49 | resolve it as a DNS hostname.
 50 | 
 51 | .TP
 52 | .BR "\-q" " or " "\-\-quiet"
 53 | Only display link-layer address. Display nothing in case of failure.
 54 | That is mostly useful when calling the program from a shell script.
 55 | 
 56 | .TP
 57 | .BR "\-r attempts" " or " "\-\-retry attempts"
 58 | Send ICMPv6 Neighbor Discovery that many times until a reply is
 59 | received, or abort. By default, ndisc6 will try 3 times before aborting
 60 | (MAX_MULTICAST_SOLICIT and MAX_UNICAST_SOLICIT from RFC2461).
 61 | 
 62 | .TP
 63 | .BR "\-s source_ip" " or " "\-\-source source_ip"
 64 | Specify the IPv6 address to be used as the source for the neighbor
 65 | solicitation packets.

 85 | Otherwise it exits with code 0. This makes it possible to use the exit
 86 | code to see if a host is on-link or not.
 87 | 
 88 | .SH DIAGNOSTICS
 89 | 
 90 | If you get no response while you know the remote host is up, it is
 91 | most likely that it is not on-link, that is to say, you must cross one
 92 | or more routers to reach it. By design, IPv6 nodes ignore ICMPv6
 93 | Neighbor Discovery packets received from nodes not on the same link
 94 | (i.e. Ethernet segment), for the sake of security. Technically, that is
 95 | done by ensuring that the Hop limit (TTL) is 255.

 17 | rdnssd \- IPv6 Recursive DNS Server discovery Daemon
 18 | .SH SYNOPSIS
 19 | .BR "rdnssd" " [" "-f" "] [" "-H merge-hook" "] [" "-r resolv-file" "]"
 20 | .BR "" "[" "-p pidfile" "] [" "-u username" "]"
 21 | 
 22 | .SH DESCRIPTON
 23 | .B rdnssd
 24 | is a daemon program providing client-side support for DNS configuration
 25 | using the Recursive DNS Server (RDNSS) option, as described in RFC 5006.
 26 | Its purpose is to supply IPv6 DNS resolvers through stateless
 27 | autoconfiguration, carried by Router Advertisements.
 28 | 
 29 | rdnssd parses RDNSS options and keeps track of resolvers to write
 30 | nameservers entries to a resolv.conf(5) configuration file. By default,
 31 | it writes its own separate file, and may call an external hook to merge
 32 | it with the main @sysconfdir@/resolv.conf. This is aimed at easing coexistence
 33 | with concurrent daemons, especially IPv4 ones, updating
 34 | @sysconfdir@/resolv.conf too.
 35 | 
 36 | On Linux, since version 2.6.24, rdnssd takes advantage of a new netlink
 37 | interface, forwarding RDNSS options validated by the kernel to userland.
 38 | Otherwise, it merely listens to all ICMPv6 traffic through a raw socket.
 39 | 
 40 | .SH OPTIONS
 41 | 
 42 | .TP
 43 | .BR "\-f" " or " "\-\-foreground"
 44 | Do not detach from the console. Run the program in the foreground.
 45 | 
 46 | .TP
 47 | .BR "\-H merge-hook" " or " "\-\-merge-hook merge-hook"
 48 | Execute this hook whenever resolv.conf is updated. If this option is
 49 | not specified, then no hook will be called.
 50 | 
 51 | .TP
 52 | .BR "\-h" " or " "\-\-help"
 53 | Display some help and exit.
 54 | 
 55 | .TP
 56 | .BR "\-p pidfile" " or " "\-\-pidfile pidfile"
 57 | Override the location of the pidfile.
 58 | 
 59 | .TP
 60 | .BR "\-r resolv-file" " or " "\-\-resolv-file resolv-file"
 61 | Set the path to the generated resolv.conf file.
 62 | 
 63 | .TP
 64 | .BR "\-u username" " or " "\-\-user username"
 65 | Override the user that the program will run as. By default, it runs as
 66 | .BR "nobody" "."
 67 | 
 68 | .TP
 69 | .BR "\-V" " or " "\-\-version"
 70 | Display program version and license and exit.
 71 | 
 72 | .SH FILES
 73 | .TP
 74 | .I @sysconfdir@/rdnssd/merge-hook
 75 | A basic merge hook shipped with rdnssd, to be called with the -H option.
 76 | 
 77 | .TP
 78 | .I @localstatedir@/run/rdnssd/resolv.conf
 79 | The default resolv.conf(5) file that rdnssd writes its configuration to.
 80 | 
 81 | .TP
 82 | .I @localstatedir@/run/rdnssd.pid
 83 | The process-id file.
 84 | 
 85 | .SH BUGS
 86 | rdnssd does not keep track of the lifetimes of the routers associated
 87 | with some DNS resolvers, whereas it should to strictly comply with RFC
 88 | 5006.
 89 | 
 90 | When rdnssd uses a raw socket instead of the netlink kernel interface,
 91 | it does not validate received Neighbor Discovery traffic in any way.
 92 | For example, it will always consider Router Advertisement packets,
 93 | whereas it should not if the host is configured as a router. When the
 94 | netlink interface is used, such validation is done by the kernel.

 31 | .BR "hostname/address" "> [" "port" "]"
 32 | 
 33 | .SH DESCRIPTON
 34 | .B rltraceroute6
 35 | is an IPv6 traceroute implementation.
 36 | 
 37 | It displays the list of hops along the network route between the local system
 38 | and specified destination, by sending packets while incrementing their hop
 39 | limit, until the final destination is reached.
 40 | 
 41 | .RB "By default, " "rltraceroute6" " sends UDP probe packets toward the"
 42 | destination (that's the historical default).
 43 | However, it can also send TCP packets, much like Michael C. Toren's
 44 | .B tcptraceroute
 45 | does on IPv4 networks; 
 46 | .B tcptraceroute6
 47 | sends TCP packets by default (and mimics tcptraceroute command line
 48 | syntax).
 49 | Finally, it can also send ICMPv6 Echo Request packets, like some other
 50 | traceroute implementations (such as the one in Microsoft Windows);
 51 | .B tracert6
 52 | does this by default.
 53 | 
 54 | You must specify the name or address of the host toward which the network
 55 | route should be determined. An optional additional parameter specifies either
 56 | the probe packets length (for UDP and ICMP packets), or the destination port
 57 | number/service name (for TCP packets).
 58 | 
 59 | Note that TCP destination port zero really is TCP port numbered 0 (which
 60 | cannot be used via the standard higer-level TCP/IP programming interface).
 61 | 
 62 | .SH OPTIONS
 63 | 
 64 | .TP
 65 | .B "\-A"
 66 | Send TCP/ACK probe packets. That's very efficient against stateless
 67 | firewalls (e.g. the official Linux kernel versions up to and including 2.4.31
 68 | and 2.6.14), and utterly helpless against stateful ones. Note that TCP/ACK
 69 | probing cannot determine whether the destination TCP port is open or not.
 70 | 
 71 | .TP
 72 | .B "\-d"
 73 | Enable socket debugging option (SO_DEBUG). Unless you are debugging the
 74 | kernel, this is probably not going to have any actual effect.
 75 | 
 76 | .TP
 77 | .B "\-E"
 78 | .RI "Send " "ECN-setup" " TCP/SYN probe packets (as per RFC 3168)"
 79 | rather than non-ECN-setup TCP/SYN probe packets. This has no effect unless
 80 | command line optin -S is specified as well.
 81 | 
 82 | .TP
 83 | .B "\-F"
 84 | This option is ignored for backward compatibility.
 85 | IPv6 packets are never fragmented en route.
 86 | 
 87 | .TP
 88 | .B "\-f"
 89 | Override the initial IPv6 packets hop limit (default: 1).
 90 | 
 91 | .TP
 92 | .B "\-g"
 93 | Add an IPv6 route segment within an IPv6 Routing Header.
 94 | This enables loose source routing.
 95 | Currently, only "Type 0" routing header is supported.
 96 | 
 97 | .TP
 98 | .B "\-h"
 99 | Display some help and exit.
100 | 
101 | .TP
102 | .B "\-I" " (rltraceroute6 only)"

104 | That's the default for tracert6.
105 | 
106 | .TP

108 | Only send packets through the specified interface.
109 | See also BUGS.
110 | 
111 | .TP

115 | 
116 | .TP
117 | .BR "\-l" " (rltraceroute6 only)"

125 | .TP
126 | .B "\-m"
127 | Override the maximum hop limit (maximum number of hops).
128 | The default is 30 hops which should be sufficient on the IPv6 Internet for
129 | some time.
130 | 
131 | .TP
132 | .B "\-N"
133 | Try to resolve each hop's IPv6 address to a host name. This is the default.
134 | This option is meant for backward compatibility with tcptraceroute(8).
135 | 
136 | .TP
137 | .B "\-n"
138 | Do not try to resolve each hop's IPv6 address to a host name.
139 | That may speed up the traceroute significantly.
140 | 
141 | .TP
142 | .B "\-p"
143 | For rltraceroute6, specify the base destination port number (default: 33434).
144 | rltraceroute6 assumes that packets toward this port up to this port plus the
145 | maximum hop limit are not in use by any program on the final destination
146 | and that they are not blocked by some firewall. The fact that this very
147 | assumption was not always correct, eventually lead to the development of the
148 | original IPv4 tcptraceroute by Michael Toren.
149 | 
150 | For tcptraceroute6, specify the source port number (default: auto).
151 | Note that source port number zero really means number zero, rather than some
152 | port number that would be automatically assigned, as is the case with usual
153 | softwares.
154 | 
155 | .TP
156 | .B "\-q"
157 | Override the number of probes sent to each hop (default: 3).
158 | 
159 | .TP
160 | .B "\-r"
161 | Do not route packets, i.e. do not send packets through a gateway that would be
162 | specified by the routing table.
163 | See also BUGS.
164 | 
165 | .TP
166 | .B "\-S"
167 | Use TCP/SYN probe packets. That's the default for tcptraceroute6.
168 | 
169 | .TP
170 | .B "\-s"
171 | Specify the source address to use for probe packets explicitly.
172 | 
173 | .TP
174 | .B "\-S"
175 | Use UDP probe packets. That's the default for rltraceroute6.
176 | 
177 | .TP
178 | .B "\-t"
179 | Specify the traffic class (DSCP) for probe packets.
180 | See also BUGS.
181 | 
182 | .TP
183 | .B "\-U" " (rltraceroute6 only)"
184 | Send UDP probe packets. That's the default.
185 | 
186 | .TP
187 | .B "\-V"
188 | Display program version and license and exit.
189 | 
190 | .TP
191 | .B "\-w"
192 | Override the delay (in seconds) to wait for response once a given probe packet
193 | was sent (default: 5 seconds).
194 | 
195 | .TP
196 | .B "\-x"
197 | This option is ignored for seamless migration from IPv4 traceroute.
198 | The IPv6 header has no checksum field.
199 | 
200 | .TP
201 | .B "\-z"
202 | Specify a milliseconds delay to wait between each probe
203 | with identical hop limit.
204 | This can be useful to work-around ICMPv6 rate limitation on some hosts.
205 | 
206 | .SH DIAGNOSTICS
207 | If a response is received, the round-trip time is printed.
208 | In addition, specific symbols denote certain errors:
209 | 
210 | .TP
211 | .BR "*" "   No response"
212 | No valid response received before the timeout delay (see -w option).
213 | 
214 | .TP
215 | .BR "!N" "  No route to destination"
216 | There is no entry for the destination network in the routing table.
217 | 
218 | .TP
219 | .BR "!A" "  Communication with destination administratively prohibited"
220 | A firewall explicitly rejected the traffic.
221 | 
222 | .TP
223 | .BR "!S"  "  Beyond scope of source address"
224 | The address scope of the source address is too small to reach the
225 | destination address. At the time of writing, this can only happen when
226 | using a link-local source address to reach a global scope destination.
227 | (Note: some IPv4 traceroute implementations use !S for source route
228 | error which is completely different)
229 | 
230 | .TP
231 | .BR "!H" "  Address unreachable"
232 | The host address is not reachable for some other reasons,
233 | particularly a link-layer failure (e.g. Neighbor discovery failure).
234 | 
235 | .TP
236 | .BR "!P" "  Unrecognized Next Header type encountered"
237 | The destination does not implement the layer-4 protocol used.
238 | You should retry with ICMPv6 Echo Requests (-I command line option)
239 | which MUST be supported by any IPv6 node.
240 | 
241 | .SH SECURITY
242 | .RI "rltraceroute6 should be " "setuid" " " "root" " to allow use by non "
243 | privileged users. It will drop its root privileges before any attempt
244 | is made to send or receive data from the network so as to reduce the possible
245 | impact of a security vulnerability.
246 | 
247 | .SH BUGS
248 | However useful they might be, -i and -r options are ignored by the
249 | official Linux kernel at the time of writing this manpage,
250 | and hence do not work as documented.
251 | 
252 | Support for option -t was broken until Linux kernel version 2.6.18.
253 | 
254 | Usage of Routing Header, with option -g, triggers an OOPS on Linux kernel
255 | versions below 2.6.17.12.
256 | 
257 | Receiving TCP/SYN-ACK packets does not work on FreeBSD at all.
258 | This severely limits the usefulness of tcptraceroute6 on FreeBSD.
259 | 
260 | Packet length takes the IPv6 header and, if present, extension headers
261 | into account.
262 | rltraceroute6 versions before 0.7.4 used it as IPv6 payload length instead,
263 | i.e. did not include the layer-3 headers in the computation.
264 | Linux iputils traceroute6 does not even include the UDP header.
265 | On the whole, the packet length semantic is very inconsistent among IPv6
266 | traceroute implementations.

 16 | .SH NAME
 17 | tcpspray \- TCP/IP bandwidth measurement tool (Discard and Echo client)
 18 | .SH SYNOPSIS
 19 | .BR "tcpspray" " [" "-46ev" "] [" "-b block_size" "] [" "-d wait_\[char181]s" "] ["
 20 | .BR "-f filename" "] [" "-n count" "] <" "hostname" "> [" "port" "]"
 21 | 
 22 | .SH DESCRIPTON
 23 | .B tcpspray
 24 | .RI "uses the " "Discard" " resp. " "Echo" " protocol (RFC\ 863 resp. RFC\ 862)"
 25 | .RI "to perform bandwidth measurements of " "TCP" " sessions between the"
 26 | .RI "local system, and a " "Discard" " resp. " "Echo" " server."
 27 | 
 28 | Unix-based hosts can provide a Discard and/or Echo servers with the Internet
 29 | .I super-server
 30 | .BR "inetd" ". On Windows NT, the
 31 | .I simple network protocols
 32 | optional component will do the same.
 33 | 
 34 | The name or address of the server node must be specified. tcpspray will
 35 | automatically try to use IPv6 when available. If not, or if it fails, it will
 36 | fallback to IPv4. However, tcpspray4 resp. tcpspray6 only try to use IPv4
 37 | resp. IPv6.
 38 | 
 39 | .SH OPTIONS
 40 | 
 41 | .TP
 42 | .BR "\-4" " or " "\-\-ipv4"
 43 | Force usage of TCP over IPv4.
 44 | 
 45 | .TP
 46 | .BR "\-6" " or " "\-\-ipv6"
 47 | Force usage of TCP over IPv6.
 48 | 
 49 | .TP
 50 | .BR "\-b block_size" " or " "\-\-bsize block_size"
 51 | Send block of the specified byte size (default: 1024).
 52 | 
 53 | .TP
 54 | .BR "\-d wait_\[char181]s" " or " "\-\-delay wait_\[char181]s"
 55 | Waits for the given amount of microseconds after any given was sent
 56 | before attempting to send the next one. There is no delay by default.
 57 | 
 58 | .TP
 59 | .BR "\-e" " or " "\-\-echo"
 60 | Use the Echo protocol instead of Discard. tcpspray will measure the
 61 | time required to send data and receive it back, instead of simply
 62 | sending it.
 63 | 
 64 | .TP
 65 | .BR "\-f filename" " or " "\-\-fill filename"
 66 | Read data from the specified file to fill sent blocks with. If the
 67 | file is smaller than the size of blocks, or if no file were specified,
 68 | the remaining trailing bytes are all set to zero.
 69 | 
 70 | .TP
 71 | .BR "\-h" " or " "\-\-help"
 72 | Display some help and exit.
 73 | 
 74 | .TP
 75 | .BR "\-n block_count" " or " "\-\-count block_count"
 76 | Send the specified amount of data blocks for the measurements
 77 | (default: 100).
 78 | 
 79 | .TP
 80 | .BR "\-V" " or " "\-\-version"
 81 | Display program version and license and exit.
 82 | 
 83 | .TP
 84 | .BR "\-v" " or " "\-\-verbose"
 85 | Display more verbose informations. In particular, tcpspray will print a dot
 86 | each time a block is sent. If the Echo protocol is used (option -e), dots
 87 | will be erased as data is received back.
 88 | 
 89 | .SH DIAGNOSTICS
 90 | 
 91 | If you get no response while you know the remote host is up, it is
 92 | most likely that it has no Discard/Echo service running, or that these
 93 | services are blocked by a firewall. Running tcptraceroute6(8) resp.
 94 | tcptraceroute(8) toward the IPv6 resp. IPv4 remote host might help detecting
 95 | such a situation.
 96 | 
 97 | .SH SECURITY
 98 | tcpspray does not require any privilege to run.

  7 | Last update: 28 December 2006
  8 | 
  9 | Interface options
 10 | ==================
 11 | 
 12 | IgnoreIfMissing (Off)		N/A (or in a way, always On)
 13 | 	ezirad automatically picks interface as they appear and disappear.
 14 | 
 15 | AdvSendAvert (Off)		always On
 16 | 	There might be some corner cases where ezirad should not answer on an
 17 | 	interface, though it would seldom cause harm to do so. Still, I wonder
 18 | 	why radvd has this option (and on top of that Off by default!). You
 19 | 	would not configure the interface if you did not send advertisements
 20 | 	on it.
 21 | 
 22 | UnicastOnly (Off)		fail-safe Off with regards to unsolicited RAs
 23 | 				always On with regards to solicited RAs
 24 | 	ezirad always replies send solicited RAs as unicast, which is legal
 25 | 	(though not the specification default), and works fine even for
 26 | 	multicast-enabled links. It even avoids broadcasting RAs to host that
 27 | 	did not request them.
 28 | 	ezirad should try to send unsoliticated RAs (multicast) on
 29 | 	IFF_MULTICAST links and ignore errors.
 30 | 	NOT IMPLEMENTED YET
 31 | 
 32 | MaxRtrAdvInterval (10 minutes)
 33 | MinRtrAdvInterval (200)
 34 | MinDelayBetweenRAs (3)
 35 | 	NOT IMPLEMENTED YET
 36 | 
 37 | AdvManagedFlag (Off)		always Off
 38 | 	ezirad is all about not managing the network, so there is probably no
 39 | 	DHCPv6 server available on hosts. If there is one, you should use
 40 | 	radvd instead.
 41 | 
 42 | AdvOtherConfigFlag (Off)	always Off
 43 | 	Same as AdvManagedFlag. However, we may want to implement DHCPv6 in
 44 | 	ezirad too, if only to provide Recursive DNS Server configuration.
 45 | 	This is a huge TODO however.
 46 | 
 47 | AdvLinkMTU (0 = Off)		always Off
 48 | 	ezirad can guess the interface MTU. Support for AdvLinkMTU is present,
 49 | 	though commented out. It is typically useless to tell other hosts to
 50 | 	use the MTU which we obtained from lower layer, as they know about it
 51 | 	too already. AdvLinkMTU is only useful if hosts need to use a lower
 52 | 	MTU for some unusual reasons (MSS clamping used to be one with broken
 53 | 	tunnels, but it has mostly disappeared as IPv6 stacks improved).
 54 | 	Worst yet, the MTU, as seen from the host running ezirad might be
 55 | 	different from the MTU as seen on other nodes. A typical scenario
 56 | 	involves an Gigabit Ethernet ezirad router (MTU=9000+) with some Fast
 57 | 	Ethernet (MTU=1500) nodes on the network segment.
 58 | 
 59 | AdvReachableTime (unspecified)	always unspeficied
 60 | AdvRetransTimer (unspecified)	always unspecified
 61 | 	The most sane default is that provided by the underlying link-layer.
 62 | 	No need to customize this.
 63 | 
 64 | AdvCurHopLimit (64)		local kernel configuration (or 128)
 65 | 
 66 | AdvDefaultLifetime (30 minutes)	always 30 minutes
 67 | 	AdvDefaultLifetime has to be non-zero otherwise the router will be
 68 | 	very useless. It also has to be multiple times MaxRtrAdvInterval so
 69 | 	that a host has little risk of loosing its autoconfiguration even if
 70 | 	it lost a 1 or 2 subsequent unsoliticed RAs.
 71 | 	That being said, it should be no bigger that radvd's own default, so
 72 | 	that an explicitly configured router will not get a lower priority on
 73 | 	the same network segment.
 74 | 
 75 | AdvDefaultPreference (Medium)	always Low
 76 | 
 77 | AdvSourceLLAddress (On)		always On (unless link has no address)
 78 | 
 79 | AdvHomeAgentFlag (Off)		always Off until Mobile IPv6 implemented
 80 | AdvHomeAgentInfo (Off)		always Off
 81 | 	ezirad should determine this automatically, but this is
 82 | 	NOT IMPLEMENTED YET.
 83 | 
 84 | HomeAgentLifetime (30 minutes)	N/A until AdvHomeAgentFlag is implemented
 85 | HomeAgentPreference (0)		always 0? always something <0 ? N/A currently
 86 | 
 87 | AdvMobRtrSupportFlag (Off)	always Off until Mobile Router implemented
 88 | 
 89 | AdvIntervalOpt (Off)		NOT IMPLEMENTED (should be always Off?)
 90 | 
 91 | 
 92 | Prefix options
 93 | ===============
 94 | 
 95 | AdvOnLink (On)			always On
 96 | 	Let alone an uncommon link layer type, this should always work fine.
 97 | 	Afterall, we trust our own addresses table.
 98 | 
 99 | AdvAutonomous (On)		On if and only if prefix length is 64 bits
100 | 	ezirad currently assumes there is no DHCPv6 server, so hosts should
101 | 	use autonomous address configuration.
102 | 
103 | AdvRouterAddr (Off)		pending Mobile IPv6 support NOT IMPLEMENTED
104 | 
105 | AdvValidLifetime (30 days)	always 30 days - should be smaller
106 | AdvPreferredLifetime (7 days)	always 7 days - should be smaller
107 | 
108 | Base6to4Interface (not used)	N/A
109 | 
110 | 
111 | Route options
112 | ==============
113 | 
114 | Route option is not currently implemented at all.
115 | 
116 | AdvRouteLifetime (30 minutes)	same as AdvDefaultLifetime
117 | AdvRoutePreference (Medium)	same as AdvDefaultPreference
118 | 
119 | 
120 | Recursive DNS Server options
121 | =============================
122 | 
123 | RDNSS is purposedly not implemented because it was not standard at the time of
124 | writing this document. Relevant options will be reviewed in due time.
