Previously, whenever more than one pass was taken over the packet, the packet contents would be dumped incorrectly (i.e., the output form -x would be wrong on little endian machines because the protocol dumpers would modify the data). Thanks to Charles Hannum (mycroft@gnu.ai.mit.edu) for reporting this problem. - Added support for decnet protocol dumping thanks to Jeff Mogul (mogul@pa.dec.com). - Fix bug that caused length of packet to be incorrectly printed (off by ether header size) for unknown ethernet types thanks to Greg Miller (gmiller@kayak.mitre.org). - Added support for IPX protocol dumping thanks to Brad Parker (brad@fcr.com). - Added check to verify IP header checksum under -v thanks to Brad Parker (brad@fcr.com). - Move packet capture code to new libpcap library (which is packaged separately). - Prototype everything and assume an ansi compiler. - print-arp.c: Print hardware ethernet addresses if they're not what we expect. - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). - print-fddi.c: Improvements. Thanks to Jeffrey Mogul (mogul@pa.dec.com). - print-icmp.c: Byte swap netmask before printing. Thanks to Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. By default, only the inner packet is dumped, appended with the token "(encap)". Under -v, both the inner and output packets are dumped (on the same line). Note that the filter applies to the original packet, not the encapsulated packet. So if you run tcpdump on a net with an IP Multicast tunnel, you cannot filter out the datagrams using the conventional syntax. (You can filter away all the ip-in-ip traffic with "not ip proto 4".) - print-nfs.c: Keep pending rpc's in circular table. Add generic nfs header and remove os dependences. Thanks to Jeffrey Mogul. - print-ospf.c: Improvements. Thanks to Jeffrey Mogul. - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords Add && and || operators v2.2.1 Tue Jun 6 17:57:22 PDT 1992 - Fix bug with -c flag. v2.2 Fri May 22 17:19:41 PDT 1992 - savefile.c: Remove hack that shouldn't have been exported. Add truncate checks. - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' matches non-echo/reply ICMP packets. - Many improvements to filter code optimizer. - Added 'multicast' keyword and extended the 'broadcast' keyword can now be so that protocol qualifications are allowed. For example, "ip broadcast" and "ether multicast" are valid filters. - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel patches to netinet/if_loop.c. - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. - Added EGP and OSPF printers, thanks to Jeffrey Honig. v2.1 Tue Jan 28 11:00:14 PST 1992 - Internal release (never publically exported). v2.0.1 Sun Jan 26 21:10:10 PDT - Various byte ordering fixes. - Add truncation checks. - inet.c: Support BSD style SIOCGIFCONF. - nametoaddr.c: Handle multi addresses for single host. - optimize.c: Rewritten. - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous for broadcast nets. - print-atal.c: Fix an alignment bug (thanks to stanonik@nprdc.navy.mil) Add missing printf() argument. - print-bootp.c: First attempt at decoding the vendor buffer. - print-domain.c: Fix truncation checks. - print-icmp.c: Calculate length of packets from the ip header. - print-ip.c: Print frag id in decimal (so it's easier to match up with non-frags). Add support for ospf, egp and igmp. - print-nfs.c: Lots of changes. - print-ntp.c: Make some verbose output depend on -v. - print-snmp.c: New version from John LoVerso. - print-tcp.c: Print rfc1072 tcp options. - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits (microseconds) worth of precision. Fix uid bugs. - A packet dumper has been added (thanks to Jeff Mogul of DECWRL). With this option, you can create an architecture independent binary trace file in real time, without the overhead of the packet printer. At a later time, the packets can be filtered (again) and printed. - BSD is supported. You must have BPF in your kernel. Since the filtering is now done in the kernel, fewer packets are dropped. In fact, with BPF and the packet dumper option, a measly Sun 3/50 can keep up with a busy network. - Compressed SLIP packets can now be dumped, provided you use our SLIP software and BPF. These packets are dumped as any other IP packet; the compressed headers are dumped with the '-e' option. - Machines with little-endian byte ordering are supported (thanks to Jeff Mogul). - Ultrix 4.0 is supported (also thanks to Jeff Mogul). - IBM RT and Stanford Enetfilter support has been added by Rayan Zachariassen . Tcpdump has been tested under both the vanilla Enetfilter interface, and the extended interface (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. - TFTP packets are now printed (requests only). - BOOTP packets are now printed. - SNMP packets are now printed. (thanks to John LoVerso of Xylogics). - Sparc architectures, including the Sparcstation-1, are now supported thanks to Steve McCanne and Craig Leres. - SunOS 4 is now supported thanks to Micky Liu of Columbia University (micky@cunixc.cc.columbia.edu). - IP options are now printed. - RIP packets are now printed. - There's a -v flag that prints out more information than the default (e.g., it will enable printing of IP ttl, tos and id) and -q flag that prints out less (e.g., it will disable interpretation of AppleTalk-in-UDP). - The grammar has undergone substantial changes (if you have an earlier version of tcpdump, you should re-read the manual entry). The most useful change is the addition of an expression syntax that lets you filter on arbitrary fields or values in the packet. E.g., "ip[0] > 0x45" would print only packets with IP options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN packets. The most painful change is that concatenation no longer means "and" -- e.g., you have to say "host foo and port bar" instead of "host foo port bar". The up side to this down is that repeated qualifiers can be omitted, making most filter expressions shorter. E.g., you can now say "ip host foo and (bar or baz)" to look at ip traffic between hosts foo and bar or between hosts foo and baz. [The old way of saying this was "ip host foo and (ip host bar or ip host baz)".] v2.0 Sun Jan 13 12:20:40 PST 1991 - Initial public release. tcpdump-4.0.0/chdlc.h0000644000076500007650000000263211056653374012560 0ustar kenken/* @(#) $Header: /tcpdump/master/tcpdump/chdlc.h,v 1.1 2000-09-18 05:11:43 guy Exp $ (LBL) */ /* * Copyright (c) 1990, 1991, 1993, 1994, 1995, 1996, 1997 * The Regents of the University of California.

Your system might provide a version of libpcap that can be installed; if so, to compile tcpdump you might need to install a "developer" version of libpcap as well as the "run-time" version. You can also install tcpdump.org's version of libpcap; see the README file in this directory for the ftp location. You will need an ANSI C compiler to build tcpdump. The configure script will abort if your compiler is not ANSI compliant. If this happens, use the GNU C compiler, available via anonymous ftp: ftp://ftp.gnu.org/pub/gnu/gcc/ After libpcap has been built (either install it with "make install" or make sure both the libpcap and tcpdump source trees are in the same directory), run ./configure (a shell script). "configure" will determine your system attributes and generate an appropriate Makefile from Makefile.in. Now build tcpdump by running "make". If everything builds ok, su and type "make install". This will install tcpdump and the manual entry. Any user will be able to use tcpdump to read saved captures. Whether a user will be able to capture traffic depends on the OS and the configuration of the system; see the tcpdump man page for details. DO NOT give untrusted users the ability to capture traffic. If a user can capture traffic, he or she could use utilities such as tcpdump to capture any traffic on your net, including passwords. Note that most systems ship tcpdump, but usually an older version. Remember to remove or rename the installed binary when upgrading. If your system is not one which we have tested tcpdump on, you may have to modify the configure script and Makefile.in. Please send us patches for any modifications you need to make. Please see "PLATFORMS" for notes about tested platforms.
