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 Library 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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.

Why did you implemented ziffy? -A. because of my own personal needs! - - -Q. What can ziffy do for me? -A. ziffy can promiscuously capture network packets from different interfaces, - including of course Ethernet, PPP and ISDN lines, and other interfaces - that your OS supports. Each packet, as read from the network, is stripped - from the lower-level protocols (Ethernet/IP/TCP) header information and - then passed to a Z39.50 ASN.1/BER Decoder. All valid Z39.50 packets are - passed to a pretty print function to show all the Z39.50 information - that the packet carries. - - -Q. Why I should use this program? -A. So, if you are interestered in Z39.50 APDUs, please give ziffy a chance - to run on your system. Perhaps you are interested in network statistics - collection, security monitoring, network debugging, etc. - - If you are a trusted user, ziffy is your friend! - - -Q. Why does ziffy use the Packet Capture Library libpcap? -A. Well, the libpcap package provides a portable framework for low-level - network monitoring. Its system-independent API helps in porting and - alleviates the need for several system-dependent packet capture modules. - libpcap is the choice by default for tools such as ziffy! - - -Q. Why does ziffy use the YAZ Toolkit by IndexData? -A. This is a long story. - To perform its task ziffy needs ASN.1 run-time BER decoding and printing - routines. - - The initial version was based on the ZETA Core Library by Finsiel S.p.A., - which in turn includes and uses the Finsiel X/ASN.1 Toolkit to perform - Z39.50 encoding/decoding/printing routines. - - I still have and maintain this version of the X/ASN.1 software. But I do not - have permissions to let this software run free on the Net because of - copyrigth restrictions. That is the reason I decided to port ziffy - on freeware ASN.1 Toolkits. - - The popular Yaz Toolkit: - o provides the required Z39.50 decoding and printing functionalities - o it is largely used in different contests by several people and organizations - o it is in the public domain - - So it is the choice by default. - Thanks to Sebastian Hammer and Adam Dickmeiss - for their superb and clean work - - -Q. Had ziffy been compiled against other public domain ASN.1 Toolkits? -A. Yes. - I have a version of ziffy written on top of the SNACC ASN.1 Toolkit, - that is not so popular in the Z39.50 community so the YAZ Toolkit does. - - If you know of other public domain ASN.1 Decoders with a pretty print - APDUs routines, please drop me a mail. - I will try to include different printing routines as run-time options - in the following releases of ziffy. - - -Q. Can I know the list of OSs and supported platforms ziffy run on? -A. I written and tested the program on my intel based linux box. - And I ported it on the Solaris 2.6. - I think it should be ported with minimal effort on - o Ultrix 4.1.3 - o Irix 6.2 - - AIX? who can say? it is a so different flavor of Unix - - NT? oh no, again! please don't ask. - - -Q. Where can I get the latest version of ziffy? -A. You can download it from ftp anonymous site: - ftp://zeta.tlcpi.finsiel.it/pub/z3950/ziffy - - -Q. Where can I get more information on ziffy? -A. Visit the ziffy official home page. - http://zeta.tlcpi.finsiel.it/z3950/ziffy - - -Q. Are there any mailinglist dedicated to ziffy? -A. No! for the time being. - - -Q.

It can be started both in interactive -mode to capture, decode and show all information in the Z39.50 APDUs from a live network, -and in batch mode to analyze the APDUs off-line from a previously created file. -\fBziffy\fR uses the standard BPF network packet filter for more reliable capture mechanism. -An additional expression can be given on the command line to capture only packets -for which \fIexpression\fP is `true'. -By default \fBziffy\fR displays Z39.50 APDUs in a single-line summary form. In this format -only the name of the captured APDU is displayed in the summary line while the underlaying TCP, -IP, and Ethernet frames information are discarded. -Multi-lines are also supported if either of verbose modes are enabled. -This allows an high degree of monitoring, from simple checks of functional processes down -to full APDUs hexacimal dump for interoperability and debugging testing phases. -.SH OPTIONS -.TP -.B \-a -Attempt to convert network addresses to names. By default, \fBziffy\fR will ___not___ -resolve IP addresses to FQDN's. -.TP -.B \-c -Capture a maximum of \fIcount\fP number of APDUs and then exit. -.TP -.B \-e -Enable the display of the link-level header. -.TP -.B \-f -Do not traslate `foreign' internet addresses. -.TP -.B \-h -Display a help screen and quit. -.TP -.B \-i -Define the name of the interface to use for live packet capture. It should match -one of the names listed in \*(L"\fBnetstat \-i\fR\*(R" or \*(L"\fBifconfig \-a\fR\*(R". -By default \fBziffy\fR will automatically choose the first non-loopback interface it finds. -.TP -.B \-l -Make stdout line buffered. Useful if you want to see the data while capturing it. -.TP -.B \-n -Disable domain name qualification of host names. -.TP -.B \-p -Set the interface in non-promiscuous mode. Only packets addressed to the local host machine -will be captured. -.TP -.B \-r -Read packet data from \fIfile\fR. Currently, \fBziffy\fR only understands -\fBpcap\fR / \fBtcpdump\fR formatted files. -.TP -.B \-s -Truncate each packet after \fIsnaplen\fP bytes when capturing live data. -No more than \fIsnaplen\fR bytes of each network packet will be read into memory, -or saved to disk. -.br -While 68 bytes is adequate for lower-level protocol such as IP, ICMP, TCP and UDP, -it is inadeguate for Z39.50 and the exact cut-off is not easy to determine. -The default value is set to 10K which should be enough for most networks. -You should limit \fIsnaplen\fP to the smallest number that will allow you to -capture all the Z39.50 protocol information. -.br -Note that taking larger snapshots both increases the amount of time it takes to -process packets and, effectively, decreases the amount of packet buffering. -This may cause packets to be lost. -.TP -.B \-t -Sets the format of the packet timestamp displayed. - -INSERIRE QUI LA SBRODOLATA PER I VARI FORMATI DI PRESENTAZIONE - -.TP -.B \-v -Print the program version and exit. -.TP -.B \-w -Write the raw Z39.50 APDUs to \fIfile\fR rather than printing them out. -They can later be printed with the \-r option. -Standard output is used if \fIfile\fR is ``-''. -.TP -.B \-1 -Set verbose output at level 1. -.TP -.B \-2 -Set verbose output at level 2. -.TP -.B \-T -With this option you can filter out certain APDU types from beeing -shown. For example, if you only wanted to see all APDU's except -"init" and "sort" you could use: -.B % \fBziffy\fR -T init -T sort -Currently known APDU types are: -\fBinit\fR -\fBseach\fR -\fBpresent\fR -\fBscan\fR -\fBsort\fR - - -.Sp -A display filter can be entered into the strip at the bottom. It must -have the same format as \fBtcpdump\fR filter strings, since both programs use -the same underlying library. -.SH EXAMPLES -.LP -To print all APDUs arriving at or departing from \fIzeta.tlcpi.finsiel.it\fP: -.RS -.nf -\fBziffy host zeta.tlcpi.finsiel.it\fP -.fi -.RE -.SH OUTPUT FORMAT -The output of \fIziffy\fP is Z39.50 APDU dependent. The following -gives a brief description and examples of most of the formats. -.SH WARNING -To run -.I ziffy -you must be root or it must be installed setuid to root. -.SH "SEE ALSO" -tcpdump(1), pcap(3), xasn1(3), yaz(7), snacc(3) -.SH NOTES -The latest version of \fBziffy\fR can be found at -\fBhttp://zeta.tlcpi.finsiel.it/ziffy\fR -.SH AUTHOR -Rocco Carbone -.SH BUGS -Please send bug reports to the author - diff --git a/ziffy/ziffy.c b/ziffy/ziffy.c deleted file mode 100644 index c0743a1..0000000 --- a/ziffy/ziffy.c +++ /dev/null @@ -1,475 +0,0 @@ -/* - * -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - * ziffy.c - a promiscuous Z39.50 APDU sniffer for Ethernet - * - * Copyright (c) 1998-2001 R.
