Reported by Terry Kennedy. 600 601- Minor fixes to the man page thanks to Mark Andrews. 602 603- Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah 604 (bmah@cs.berkeley.edu). 605 606- Added support for new dns types, thanks to Rainer Orth. 607 608- Fixed tftp_print() to print the block number for ACKs. 609 610- Document -dd and -ddd. Resulted from a bug report from Charlie Slater 611 (cslater@imatek.com). 612 613- Check return status from malloc/calloc/etc. 614 615- Check return status from pcap_loop() so we can print an error and 616 exit with a bad status if there were problems. 617 618- Bail if ip option length is <= 0. Resulted from a bug report from 619 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au). 620 621- Print out a little more information for sun rpc packets. 622 623- Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu). 624 625- Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were 626 wrong on little endian machines). 627 628- Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford 629 (crawdad@fnal.gov). 630 631- Fix ntp_print() to not print garbage when the stratum is 632 "unspecified."

Thanks to Yoshitaka Tokugawa 642 (toku@dit.co.jp) 643 644- Don't checksum ip header if we don't have all of it. Thanks to John 645 Hawkinson (jhawk@mit.edu). 646 647- Print out hostnames if possible in egp printer. Thanks to Jeffrey 648 Honig (jhc@bsdi.com) 649 650 651v3.1a1 Wed May 3 19:21:11 PDT 1995 652 653- Include time.h when SVR4 is defined to avoid problems under Solaris 654 2.3. 655 656- Fix etheraddr_string() in the ETHER_SERVICE to return the saved 657 strings, not the local buffer. Thanks to Stefan Petri 658 (petri@ibr.cs.tu-bs.de). 659 660- Detect when pcap raises the snaplen (e.g. with snit). Print a warning 661 that the selected value was not used. Thanks to Pascal Hennequin 662 (Pascal.Hennequin@hugo.int-evry.fr). 663 664- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin. 665 666- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu). 667 668v3.0.3 Sun Oct 1 18:35:00 GMT 1995 669 670- Although there never was a 3.0.3 release, the linux boys cleverly 671 "released" one in late 1995. 672 673v3.0.2 Thu Apr 20 21:28:16 PDT 1995 674 675- Change configuration to not use gcc v2 flags with gcc v1. 676 677- Redo gmt2local() so that it works under BSDI (which seems to return 678 an empty timezone struct from gettimeofday()). Based on report from 679 Terry Kennedy (terry@spcvxa.spc.edu). 680 681- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based 682 on report from Mark Andrews (mandrews@alias.com). 683 684- Don't pass cc flags to gcc. Resulted from a bug report from Rainer 685 Orth (ro@techfak.uni-bielefeld.de). 686 687- Fixed printout of connection id for uncompressed tcp slip packets. 688 Resulted from a bug report from Richard Stevens (rstevens@noao.edu). 689 690- Hack around deficiency in Ultrix's make. 691 692- Add ETHERTYPE_TRAIL define which is missing from irix5. 693 694v3.0.1 Wed Aug 31 22:42:26 PDT 1994 695 696- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4. 697 698v3.0 Mon Jun 20 19:23:27 PDT 1994 699 700- Added support for printing tcp option timestamps thanks to 701 Mark Andrews (mandrews@alias.com). 702 703- Reorganize protocol dumpers to take const pointers to packets so they 704 never change the contents (i.e., they used to do endian conversions 705 in place). Previously, whenever more than one pass was taken over 706 the packet, the packet contents would be dumped incorrectly (i.e., 707 the output form -x would be wrong on little endian machines because 708 the protocol dumpers would modify the data). Thanks to Charles Hannum 709 (mycroft@gnu.ai.mit.edu) for reporting this problem. 710 711- Added support for decnet protocol dumping thanks to Jeff Mogul 712 (mogul@pa.dec.com). 713 714- Fix bug that caused length of packet to be incorrectly printed 715 (off by ether header size) for unknown ethernet types thanks 716 to Greg Miller (gmiller@kayak.mitre.org). 717 718- Added support for IPX protocol dumping thanks to Brad Parker 719 (brad@fcr.com). 720 721- Added check to verify IP header checksum under -v thanks to 722 Brad Parker (brad@fcr.com). 723 724- Move packet capture code to new libpcap library (which is 725 packaged separately). 726 727- Prototype everything and assume an ansi compiler. 728 729- print-arp.c: Print hardware ethernet addresses if they're not 730 what we expect. 731 732- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. 733 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). 734 735- print-fddi.c: Improvements. Thanks to Jeffrey Mogul 736 (mogul@pa.dec.com). 737 738- print-icmp.c: Byte swap netmask before printing. Thanks to 739 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. 740 741- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. 742 By default, only the inner packet is dumped, appended with the token 743 "(encap)". Under -v, both the inner and output packets are dumped 744 (on the same line). Note that the filter applies to the original packet, 745 not the encapsulated packet. So if you run tcpdump on a net with an 746 IP Multicast tunnel, you cannot filter out the datagrams using the 747 conventional syntax. (You can filter away all the ip-in-ip traffic 748 with "not ip proto 4".) 749 750- print-nfs.c: Keep pending rpc's in circular table. Add generic 751 nfs header and remove os dependences. Thanks to Jeffrey Mogul. 752 753- print-ospf.c: Improvements. Thanks to Jeffrey Mogul. 754 755- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" 756 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords 757 Add && and || operators 758 759v2.2.1 Tue Jun 6 17:57:22 PDT 1992 760 761- Fix bug with -c flag. 762 763v2.2 Fri May 22 17:19:41 PDT 1992 764 765- savefile.c: Remove hack that shouldn't have been exported. Add 766 truncate checks. 767 768- Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' 769 matches non-echo/reply ICMP packets. 770 771- Many improvements to filter code optimizer. 772 773- Added 'multicast' keyword and extended the 'broadcast' keyword can now be 774 so that protocol qualifications are allowed. For example, "ip broadcast" 775 and "ether multicast" are valid filters. 776 777- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). 778 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel 779 patches to netinet/if_loop.c. 780 781- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. 782 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. 783 784- Added EGP and OSPF printers, thanks to Jeffrey Honig. 785 786v2.1 Tue Jan 28 11:00:14 PST 1992 787 788- Internal release (never publically exported). 789 790v2.0.1 Sun Jan 26 21:10:10 PDT 791 792- Various byte ordering fixes. 793 794- Add truncation checks. 795 796- inet.c: Support BSD style SIOCGIFCONF. 797 798- nametoaddr.c: Handle multi addresses for single host. 799 800- optimize.c: Rewritten. 801 802- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous 803 for broadcast nets. 804 805- print-atal.c: Fix an alignment bug (thanks to 806 stanonik@nprdc.navy.mil) Add missing printf() argument. 807 808- print-bootp.c: First attempt at decoding the vendor buffer. 809 810- print-domain.c: Fix truncation checks. 811 812- print-icmp.c: Calculate length of packets from the ip header. 813 814- print-ip.c: Print frag id in decimal (so it's easier to match up 815 with non-frags). Add support for ospf, egp and igmp. 816 817- print-nfs.c: Lots of changes. 818 819- print-ntp.c: Make some verbose output depend on -v. 820 821- print-snmp.c: New version from John LoVerso. 822 823- print-tcp.c: Print rfc1072 tcp options. 824 825- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits 826 (microseconds) worth of precision. Fix uid bugs. 827 828- A packet dumper has been added (thanks to Jeff Mogul of DECWRL). 829 With this option, you can create an architecture independent binary 830 trace file in real time, without the overhead of the packet printer. 831 At a later time, the packets can be filtered (again) and printed. 832 833- BSD is supported. You must have BPF in your kernel. 834 Since the filtering is now done in the kernel, fewer packets are 835 dropped. In fact, with BPF and the packet dumper option, a measly 836 Sun 3/50 can keep up with a busy network. 837 838- Compressed SLIP packets can now be dumped, provided you use our 839 SLIP software and BPF. These packets are dumped as any other IP 840 packet; the compressed headers are dumped with the '-e' option. 841 842- Machines with little-endian byte ordering are supported (thanks to 843 Jeff Mogul). 844 845- Ultrix 4.0 is supported (also thanks to Jeff Mogul). 846 847- IBM RT and Stanford Enetfilter support has been added by 848 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under 849 both the vanilla Enetfilter interface, and the extended interface 850 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. 851 852- TFTP packets are now printed (requests only). 853 854- BOOTP packets are now printed. 855 856- SNMP packets are now printed. (thanks to John LoVerso of Xylogics). 857 858- Sparc architectures, including the Sparcstation-1, are now 859 supported thanks to Steve McCanne and Craig Leres. 860 861- SunOS 4 is now supported thanks to Micky Liu of Columbia 862 University (micky@cunixc.cc.columbia.edu). 863 864- IP options are now printed. 865 866- RIP packets are now printed. 867 868- There's a -v flag that prints out more information than the 869 default (e.g., it will enable printing of IP ttl, tos and id) 870 and -q flag that prints out less (e.g., it will disable 871 interpretation of AppleTalk-in-UDP). 872 873- The grammar has undergone substantial changes (if you have an 874 earlier version of tcpdump, you should re-read the manual 875 entry). 876 877 The most useful change is the addition of an expression 878 syntax that lets you filter on arbitrary fields or values in the 879 packet. E.g., "ip[0] > 0x45" would print only packets with IP 880 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN 881 packets. 882 883 The most painful change is that concatenation no longer means 884 "and" -- e.g., you have to say "host foo and port bar" instead 885 of "host foo port bar". The up side to this down is that 886 repeated qualifiers can be omitted, making most filter 887 expressions shorter. E.g., you can now say "ip host foo and 888 (bar or baz)" to look at ip traffic between hosts foo and bar or 889 between hosts foo and baz. [The old way of saying this was "ip 890 host foo and (ip host bar or ip host baz)".] 891 892v2.0 Sun Jan 13 12:20:40 PST 1991 893 894- Initial public release. 895
