Fix the SACK code to print the N blocks (instead of the 726 first block N times). 727 728- Don't say really small UDP packets are truncated just because they 729 aren't big enough to be a RPC. As noted by David Sacerdote. 730 731v3.2.1 Sun Jul 14 03:02:26 PDT 1996 732 733- Added rfc1716 icmp codes as suggested by Martin Fredriksson 734 (martin@msp.se) 735 736- Print mtu for icmp unreach need frag packets.

Thanks to Jeffrey 754 Mogul (mogul@pa.dec.com) 755 756- Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop. 757 Thanks to John Hawkinson. 758 759- Added some more packet truncation checks. 760 761- On systems that have it, use sigset() instead of signal() since 762 signal() has different semantics on these systems. 763 764- Fixed some more alignment problems on the alpha. 765 766- Add code to massage unprintable characters in the domain and ipx 767 printers. Thanks to John Hawkinson. 768 769- Added explicit netmask support.

Based on report from 915 Terry Kennedy (terry@spcvxa.spc.edu). 916 917- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based 918 on report from Mark Andrews (mandrews@alias.com). 919 920- Don't pass cc flags to gcc.

Previously, whenever more than one pass was taken over 942 the packet, the packet contents would be dumped incorrectly (i.e., 943 the output form -x would be wrong on little endian machines because 944 the protocol dumpers would modify the data). Thanks to Charles Hannum 945 (mycroft@gnu.ai.mit.edu) for reporting this problem. 946 947- Added support for decnet protocol dumping thanks to Jeff Mogul 948 (mogul@pa.dec.com). 949 950- Fix bug that caused length of packet to be incorrectly printed 951 (off by ether header size) for unknown ethernet types thanks 952 to Greg Miller (gmiller@kayak.mitre.org). 953 954- Added support for IPX protocol dumping thanks to Brad Parker 955 (brad@fcr.com). 956 957- Added check to verify IP header checksum under -v thanks to 958 Brad Parker (brad@fcr.com). 959 960- Move packet capture code to new libpcap library (which is 961 packaged separately). 962 963- Prototype everything and assume an ansi compiler. 964 965- print-arp.c: Print hardware ethernet addresses if they're not 966 what we expect. 967 968- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. 969 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). 970 971- print-fddi.c: Improvements. Thanks to Jeffrey Mogul 972 (mogul@pa.dec.com). 973 974- print-icmp.c: Byte swap netmask before printing. Thanks to 975 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. 976 977- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. 978 By default, only the inner packet is dumped, appended with the token 979 "(encap)". Under -v, both the inner and output packets are dumped 980 (on the same line). Note that the filter applies to the original packet, 981 not the encapsulated packet. So if you run tcpdump on a net with an 982 IP Multicast tunnel, you cannot filter out the datagrams using the 983 conventional syntax. (You can filter away all the ip-in-ip traffic 984 with "not ip proto 4".) 985 986- print-nfs.c: Keep pending rpc's in circular table. Add generic 987 nfs header and remove os dependences. Thanks to Jeffrey Mogul. 988 989- print-ospf.c: Improvements. Thanks to Jeffrey Mogul. 990 991- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" 992 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords 993 Add && and || operators 994 995v2.2.1 Tue Jun 6 17:57:22 PDT 1992 996 997- Fix bug with -c flag. 998 999v2.2 Fri May 22 17:19:41 PDT 1992 1000 1001- savefile.c: Remove hack that shouldn't have been exported. Add 1002 truncate checks. 1003 1004- Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' 1005 matches non-echo/reply ICMP packets. 1006 1007- Many improvements to filter code optimizer. 1008 1009- Added 'multicast' keyword and extended the 'broadcast' keyword can now be 1010 so that protocol qualifications are allowed. For example, "ip broadcast" 1011 and "ether multicast" are valid filters. 1012 1013- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). 1014 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel 1015 patches to netinet/if_loop.c. 1016 1017- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. 1018 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. 1019 1020- Added EGP and OSPF printers, thanks to Jeffrey Honig. 1021 1022v2.1 Tue Jan 28 11:00:14 PST 1992 1023 1024- Internal release (never publically exported). 1025 1026v2.0.1 Sun Jan 26 21:10:10 PDT 1027 1028- Various byte ordering fixes. 1029 1030- Add truncation checks. 1031 1032- inet.c: Support BSD style SIOCGIFCONF. 1033 1034- nametoaddr.c: Handle multi addresses for single host. 1035 1036- optimize.c: Rewritten. 1037 1038- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous 1039 for broadcast nets. 1040 1041- print-atal.c: Fix an alignment bug (thanks to 1042 stanonik@nprdc.navy.mil) Add missing printf() argument. 1043 1044- print-bootp.c: First attempt at decoding the vendor buffer. 1045 1046- print-domain.c: Fix truncation checks. 1047 1048- print-icmp.c: Calculate length of packets from the ip header. 1049 1050- print-ip.c: Print frag id in decimal (so it's easier to match up 1051 with non-frags). Add support for ospf, egp and igmp. 1052 1053- print-nfs.c: Lots of changes. 1054 1055- print-ntp.c: Make some verbose output depend on -v. 1056 1057- print-snmp.c: New version from John LoVerso. 1058 1059- print-tcp.c: Print rfc1072 tcp options. 1060 1061- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits 1062 (microseconds) worth of precision. Fix uid bugs. 1063 1064- A packet dumper has been added (thanks to Jeff Mogul of DECWRL). 1065 With this option, you can create an architecture independent binary 1066 trace file in real time, without the overhead of the packet printer. 1067 At a later time, the packets can be filtered (again) and printed. 1068 1069- BSD is supported. You must have BPF in your kernel. 1070 Since the filtering is now done in the kernel, fewer packets are 1071 dropped. In fact, with BPF and the packet dumper option, a measly 1072 Sun 3/50 can keep up with a busy network. 1073 1074- Compressed SLIP packets can now be dumped, provided you use our 1075 SLIP software and BPF. These packets are dumped as any other IP 1076 packet; the compressed headers are dumped with the '-e' option. 1077 1078- Machines with little-endian byte ordering are supported (thanks to 1079 Jeff Mogul). 1080 1081- Ultrix 4.0 is supported (also thanks to Jeff Mogul). 1082 1083- IBM RT and Stanford Enetfilter support has been added by 1084 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under 1085 both the vanilla Enetfilter interface, and the extended interface 1086 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. 1087 1088- TFTP packets are now printed (requests only). 1089 1090- BOOTP packets are now printed. 1091 1092- SNMP packets are now printed. (thanks to John LoVerso of Xylogics). 1093 1094- Sparc architectures, including the Sparcstation-1, are now 1095 supported thanks to Steve McCanne and Craig Leres. 1096 1097- SunOS 4 is now supported thanks to Micky Liu of Columbia 1098 University (micky@cunixc.cc.columbia.edu). 1099 1100- IP options are now printed. 1101 1102- RIP packets are now printed. 1103 1104- There's a -v flag that prints out more information than the 1105 default (e.g., it will enable printing of IP ttl, tos and id) 1106 and -q flag that prints out less (e.g., it will disable 1107 interpretation of AppleTalk-in-UDP). 1108 1109- The grammar has undergone substantial changes (if you have an 1110 earlier version of tcpdump, you should re-read the manual 1111 entry). 1112 1113 The most useful change is the addition of an expression 1114 syntax that lets you filter on arbitrary fields or values in the 1115 packet. E.g., "ip[0] > 0x45" would print only packets with IP 1116 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN 1117 packets. 1118 1119 The most painful change is that concatenation no longer means 1120 "and" -- e.g., you have to say "host foo and port bar" instead 1121 of "host foo port bar". The up side to this down is that 1122 repeated qualifiers can be omitted, making most filter 1123 expressions shorter. E.g., you can now say "ip host foo and 1124 (bar or baz)" to look at ip traffic between hosts foo and bar or 1125 between hosts foo and baz. [The old way of saying this was "ip 1126 host foo and (ip host bar or ip host baz)".] 1127 1128v2.0 Sun Jan 13 12:20:40 PST 1991 1129 1130- Initial public release. 1131
