Based on report from 953 Terry Kennedy (terry (a] spcvxa.spc.edu). 954 955 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based 956 on report from Mark Andrews (mandrews (a] alias.com). 957 958 - Don't pass cc flags to gcc.

Previously, whenever more than one pass was taken over 980 the packet, the packet contents would be dumped incorrectly (i.e., 981 the output form -x would be wrong on little endian machines because 982 the protocol dumpers would modify the data). Thanks to Charles Hannum 983 (mycroft (a] gnu.ai.mit.edu) for reporting this problem. 984 985 - Added support for decnet protocol dumping thanks to Jeff Mogul 986 (mogul (a] pa.dec.com). 987 988 - Fix bug that caused length of packet to be incorrectly printed 989 (off by ether header size) for unknown ethernet types thanks 990 to Greg Miller (gmiller (a] kayak.mitre.org). 991 992 - Added support for IPX protocol dumping thanks to Brad Parker 993 (brad (a] fcr.com). 994 995 - Added check to verify IP header checksum under -v thanks to 996 Brad Parker (brad (a] fcr.com). 997 998 - Move packet capture code to new libpcap library (which is 999 packaged separately). 1000 1001 - Prototype everything and assume an ansi compiler. 1002 1003 - print-arp.c: Print hardware ethernet addresses if they're not 1004 what we expect. 1005 1006 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. 1007 Many helpful suggestions from Gordon Ross (gwr (a] jericho.mc.com). 1008 1009 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul 1010 (mogul (a] pa.dec.com). 1011 1012 - print-icmp.c: Byte swap netmask before printing. Thanks to 1013 Richard Stevens (rstevens (a] noao.edu). Print icmp type when unknown. 1014 1015 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. 1016 By default, only the inner packet is dumped, appended with the token 1017 "(encap)". Under -v, both the inner and output packets are dumped 1018 (on the same line). Note that the filter applies to the original packet, 1019 not the encapsulated packet. So if you run tcpdump on a net with an 1020 IP Multicast tunnel, you cannot filter out the datagrams using the 1021 conventional syntax. (You can filter away all the ip-in-ip traffic 1022 with "not ip proto 4".) 1023 1024 - print-nfs.c: Keep pending rpc's in circular table. Add generic 1025 nfs header and remove os dependences. Thanks to Jeffrey Mogul. 1026 1027 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul. 1028 1029 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" 1030 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords 1031 Add && and || operators 1032 1033 v2.2.1 Tue Jun 6 17:57:22 PDT 1992 1034 1035 - Fix bug with -c flag. 1036 1037 v2.2 Fri May 22 17:19:41 PDT 1992 1038 1039 - savefile.c: Remove hack that shouldn't have been exported. Add 1040 truncate checks. 1041 1042 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' 1043 matches non-echo/reply ICMP packets. 1044 1045 - Many improvements to filter code optimizer. 1046 1047 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be 1048 so that protocol qualifications are allowed. For example, "ip broadcast" 1049 and "ether multicast" are valid filters. 1050 1051 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). 1052 Jeffrey Honig (jch (a] MITCHELL.CIT.CORNELL.EDU) contributed the kernel 1053 patches to netinet/if_loop.c. 1054 1055 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. 1056 Contact Jeffrey Honig (jch (a] MITCHELL.CIT.CORNELL.EDU) for the diffs. 1057 1058 - Added EGP and OSPF printers, thanks to Jeffrey Honig. 1059 1060 v2.1 Tue Jan 28 11:00:14 PST 1992 1061 1062 - Internal release (never publically exported). 1063 1064 v2.0.1 Sun Jan 26 21:10:10 PDT 1065 1066 - Various byte ordering fixes. 1067 1068 - Add truncation checks. 1069 1070 - inet.c: Support BSD style SIOCGIFCONF. 1071 1072 - nametoaddr.c: Handle multi addresses for single host. 1073 1074 - optimize.c: Rewritten. 1075 1076 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous 1077 for broadcast nets. 1078 1079 - print-atal.c: Fix an alignment bug (thanks to 1080 stanonik (a] nprdc.navy.mil) Add missing printf() argument. 1081 1082 - print-bootp.c: First attempt at decoding the vendor buffer. 1083 1084 - print-domain.c: Fix truncation checks. 1085 1086 - print-icmp.c: Calculate length of packets from the ip header. 1087 1088 - print-ip.c: Print frag id in decimal (so it's easier to match up 1089 with non-frags). Add support for ospf, egp and igmp. 1090 1091 - print-nfs.c: Lots of changes. 1092 1093 - print-ntp.c: Make some verbose output depend on -v. 1094 1095 - print-snmp.c: New version from John LoVerso. 1096 1097 - print-tcp.c: Print rfc1072 tcp options. 1098 1099 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits 1100 (microseconds) worth of precision. Fix uid bugs. 1101 1102 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL). 1103 With this option, you can create an architecture independent binary 1104 trace file in real time, without the overhead of the packet printer. 1105 At a later time, the packets can be filtered (again) and printed. 1106 1107 - BSD is supported. You must have BPF in your kernel. 1108 Since the filtering is now done in the kernel, fewer packets are 1109 dropped. In fact, with BPF and the packet dumper option, a measly 1110 Sun 3/50 can keep up with a busy network. 1111 1112 - Compressed SLIP packets can now be dumped, provided you use our 1113 SLIP software and BPF. These packets are dumped as any other IP 1114 packet; the compressed headers are dumped with the '-e' option. 1115 1116 - Machines with little-endian byte ordering are supported (thanks to 1117 Jeff Mogul). 1118 1119 - Ultrix 4.0 is supported (also thanks to Jeff Mogul). 1120 1121 - IBM RT and Stanford Enetfilter support has been added by 1122 Rayan Zachariassen <rayan (a] canet.ca>. Tcpdump has been tested under 1123 both the vanilla Enetfilter interface, and the extended interface 1124 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. 1125 1126 - TFTP packets are now printed (requests only). 1127 1128 - BOOTP packets are now printed. 1129 1130 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics). 1131 1132 - Sparc architectures, including the Sparcstation-1, are now 1133 supported thanks to Steve McCanne and Craig Leres. 1134 1135 - SunOS 4 is now supported thanks to Micky Liu of Columbia 1136 University (micky (a] cunixc.cc.columbia.edu). 1137 1138 - IP options are now printed. 1139 1140 - RIP packets are now printed. 1141 1142 - There's a -v flag that prints out more information than the 1143 default (e.g., it will enable printing of IP ttl, tos and id) 1144 and -q flag that prints out less (e.g., it will disable 1145 interpretation of AppleTalk-in-UDP). 1146 1147 - The grammar has undergone substantial changes (if you have an 1148 earlier version of tcpdump, you should re-read the manual 1149 entry). 1150 1151 The most useful change is the addition of an expression 1152 syntax that lets you filter on arbitrary fields or values in the 1153 packet. E.g., "ip[0] > 0x45" would print only packets with IP 1154 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN 1155 packets. 1156 1157 The most painful change is that concatenation no longer means 1158 "and" -- e.g., you have to say "host foo and port bar" instead 1159 of "host foo port bar". The up side to this down is that 1160 repeated qualifiers can be omitted, making most filter 1161 expressions shorter. E.g., you can now say "ip host foo and 1162 (bar or baz)" to look at ip traffic between hosts foo and bar or 1163 between hosts foo and baz. [The old way of saying this was "ip 1164 host foo and (ip host bar or ip host baz)".] 1165 1166 v2.0 Sun Jan 13 12:20:40 PST 1991 1167 1168 - Initial public release. 1169
