847  autoconf version is broken (it only puts the library name in the
848  cache variable name). Thanks to John Hawkinson.
849
850- Add a local autoconf macro to check for types; the autoconf version
851  is broken (it uses grep instead of actually compiling a code fragment).
852
853- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
854  formats.
855
856- Extend OSF ip header workaround to versions 1 and 2.
857
858- Fix some signed problems in the nfs printer. As reported by David
859  Sacerdote (davids@silence.secnet.com)
860
861- Detect group wheel and use it as the default since BSD/OS' install
862  can't hack numeric groups. Reported by David Sacerdote.
863
864- AIX needs special loader options. Thanks to Jonathan I. Kamens
865  (jik@cam.ov.com)
866
867- Fixed the nfs printer to print port numbers in decimal. Thanks to
868  Kent Vander Velden (graphix@iastate.edu)
869
870- Find installed libpcap in /usr/local/lib when not using gcc.
871
872- Disallow network masks with non-network bits set.
873
874- Attempt to detect "egcs" versions of gcc.
875
876- Add missing closing double quotes when displaying bootp strings.
877  Reported by Viet-Trung Luu (vluu@picard.math.uwaterloo.ca)
878
879v3.3 Sat Nov 30 20:56:27 PST 1996
880
881- Added Linux support.
882
883- GRE encapsulated packet printer thanks to John Hawkinson
884  (jhawk@mit.edu)
885
886- Rewrite gmt2local() to avoid problematic os dependencies.
887
888- Suppress nfs truncation message on errors.
889
890- Add missing m4 quoting in AC_LBL_UNALIGNED_ACCESS autoconf macro.
891  Reported by Joachim Ott (ott@ardala.han.de)
892
893- Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.
894
895- Print arp hardware type in host order. Thanks to Onno van der Linden
896  (onno@simplex.nl)
897
898- Avoid solaris compiler warnings. Thanks to Bruce Barnett
899  (barnett@grymoire.crd.ge.com)
900
901- Fix rip printer to not print one more route than is actually in the
902  packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
903  Bill Fenner (fenner@parc.xerox.com)
904
905- Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
906
907- Fix dvmrp printer truncation checks and add a dvmrp probe printer.
908  Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
909
910- Rewrite ospf printer to improve truncation checks.
911
912- Don't parse tcp options past the EOL. As noted by David Sacerdote
913  (davids@secnet.com). Also, check tcp options to make sure they ar
914  actually in the tcp header (in addition to the normal truncation
915  checks). Fix the SACK code to print the N blocks (instead of the
916  first block N times).
917
918- Don't say really small UDP packets are truncated just because they
919  aren't big enough to be a RPC. As noted by David Sacerdote.
920
921v3.2.1 Sun Jul 14 03:02:26 PDT 1996
922
923- Added rfc1716 icmp codes as suggested by Martin Fredriksson

926- Print mtu for icmp unreach need frag packets. Thanks to John
927  Hawkinson (jhawk@mit.edu)
928
929- Decode icmp router discovery messages. Thanks to Jeffrey Honig
930  (jch@bsdi.com)

933  (kushida@trl.ibm.co.jp)
934
935- Check igmp checksum if possible. Thanks to John Hawkinson.
936
937- Made changes for SINIX. Thanks to Andrej Borsenkow
938  (borsenkow.msk@sni.de)
939
940- Use autoconf's idea of the top level directory in install targets.
941  Thanks to John Hawkinson.
942
943- Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
944  Mogul (mogul@pa.dec.com)
945
946- Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
947  Thanks to John Hawkinson.
948
949- Added some more packet truncation checks.
950
951- On systems that have it, use sigset() instead of signal() since
952  signal() has different semantics on these systems.
953
954- Fixed some more alignment problems on the alpha.
955
956- Add code to massage unprintable characters in the domain and ipx
957  printers. Thanks to John Hawkinson.

969
970- Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
971  Kennedy (terry@spcvxa.spc.edu)
972
973- Fixed snmp extended tag field parsing bug. Thanks to Pascal Hennequin
974  (pascal.hennequin@hugo.int-evry.fr)
975
976- Added some ETHERTYPEs missing on some systems.
977
978- Added truncated packet macros and various checks.
979
980- Fixed endian problems with the DECnet printer.
981
982- Use $CC when checking gcc version. Thanks to Carl Lindberg
983  (carl_lindberg@blacksmith.com)
984
985- Fixes for AIX (although this system is not yet supported). Thanks to
986  John Hawkinson.
987
988- Fix bugs in the autoconf misaligned accesses code fragment.
989
990- Include sys/param.h to get BYTE_ORDER in a few places. Thanks to
991  Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp)
992
993v3.2 Sun Jun 23 02:28:10 PDT 1996
994
995- Print new icmp unreachable codes as suggested by Martin Fredriksson
996  (martin@msp.se). Also print code value when unknown for icmp redirect
997  and time exceeded.
998
999- Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1000
1001- Define "new" domain record types if not found in arpa/nameserv.h.
1002  Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also
1003  fixed an endian bug when printing mx record and added some new record
1004  types.
1005
1006- Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1007
1008- Added T/TCP options printing. As suggested by Richard Stevens
1009  (rstevens@noao.edu)
1010
1011- Use autoconf to detect architectures that can't handle misaligned
1012  accesses.
1013
1014v3.1 Thu Jun 13 20:59:32 PDT 1996
1015
1016- Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1017  and bind (as suggested by Charles Hannum).
1018
1019- Port to GNU autoconf.
1020
1021- Add support for printing DVMRP and PIM traffic thanks to
1022  Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1023
1024- Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1025  define being referenced. Reported by Terry Kennedy.
1026
1027- Minor fixes to the man page thanks to Mark Andrews.
1028
1029- Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah
1030  (bmah@cs.berkeley.edu).
1031
1032- Added support for new dns types, thanks to Rainer Orth.
1033
1034- Fixed tftp_print() to print the block number for ACKs.
1035
1036- Document -dd and -ddd. Resulted from a bug report from Charlie Slater
1037  (cslater@imatek.com).
1038
1039- Check return status from malloc/calloc/etc.
1040
1041- Check return status from pcap_loop() so we can print an error and
1042  exit with a bad status if there were problems.
1043
1044- Bail if ip option length is <= 0. Resulted from a bug report from
1045  Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1046
1047- Print out a little more information for sun rpc packets.
1048
1049- Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1050
1051- Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1052  wrong on little endian machines).
1053
1054- Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1055  (crawdad@fnal.gov).
1056
1057- Fix ntp_print() to not print garbage when the stratum is
1058  "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
1059
1060- Rewrote tcp options printer code to check for truncation. Added
1061  selective acknowledgment case.
1062
1063- Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
1064  (jch@bsdi.com)
1065
1066- Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1067  octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1068  (toku@dit.co.jp)
1069
1070- Don't checksum ip header if we don't have all of it. Thanks to John
1071  Hawkinson (jhawk@mit.edu).
1072
1073- Print out hostnames if possible in egp printer. Thanks to Jeffrey
1074  Honig (jhc@bsdi.com)
1075
1076
1077v3.1a1 Wed May  3 19:21:11 PDT 1995
1078
1079- Include time.h when SVR4 is defined to avoid problems under Solaris
1080  2.3.
1081
1082- Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1083  strings, not the local buffer. Thanks to Stefan Petri
1084  (petri@ibr.cs.tu-bs.de).
1085
1086- Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1087  that the selected value was not used. Thanks to Pascal Hennequin
1088  (Pascal.Hennequin@hugo.int-evry.fr).
1089
1090- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1091
1092- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1093
1094v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1095
1096- Although there never was a 3.0.3 release, the linux boys cleverly
1097  "released" one in late 1995.
1098
1099v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1100
1101- Change configuration to not use gcc v2 flags with gcc v1.
1102
1103- Redo gmt2local() so that it works under BSDI (which seems to return
1104  an empty timezone struct from gettimeofday()). Based on report from
1105  Terry Kennedy (terry@spcvxa.spc.edu).
1106
1107- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1108  on report from Mark Andrews (mandrews@alias.com).
1109
1110- Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1111  Orth (ro@techfak.uni-bielefeld.de).
1112
1113- Fixed printout of connection id for uncompressed tcp slip packets.
1114  Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1115
1116- Hack around deficiency in Ultrix's make.
1117
1118- Add ETHERTYPE_TRAIL define which is missing from irix5.
1119
1120v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1121
1122- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1123
1124v3.0 Mon Jun 20 19:23:27 PDT 1994
1125
1126- Added support for printing tcp option timestamps thanks to
1127  Mark Andrews (mandrews@alias.com).
1128
1129- Reorganize protocol dumpers to take const pointers to packets so they
1130  never change the contents (i.e., they used to do endian conversions
1131  in place).  Previously, whenever more than one pass was taken over
1132  the packet, the packet contents would be dumped incorrectly (i.e.,
1133  the output form -x would be wrong on little endian machines because
1134  the protocol dumpers would modify the data).  Thanks to Charles Hannum
1135  (mycroft@gnu.ai.mit.edu) for reporting this problem.
1136
1137- Added support for decnet protocol dumping thanks to Jeff Mogul
1138  (mogul@pa.dec.com).
1139
1140- Fix bug that caused length of packet to be incorrectly printed
1141  (off by ether header size) for unknown ethernet types thanks
1142  to Greg Miller (gmiller@kayak.mitre.org).
1143
1144- Added support for IPX protocol dumping thanks to Brad Parker
1145  (brad@fcr.com).
1146
1147- Added check to verify IP header checksum under -v thanks to
1148  Brad Parker (brad@fcr.com).
1149
1150- Move packet capture code to new libpcap library (which is
1151  packaged separately).
1152
1153- Prototype everything and assume an ansi compiler.
1154
1155- print-arp.c: Print hardware ethernet addresses if they're not
1156  what we expect.
1157
1158- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1159  Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1160
1161- print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1162  (mogul@pa.dec.com).
1163
1164- print-icmp.c: Byte swap netmask before printing. Thanks to
1165  Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1166
1167- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1168  By default, only the inner packet is dumped, appended with the token
1169  "(encap)".  Under -v, both the inner and output packets are dumped
1170  (on the same line).  Note that the filter applies to the original packet,
1171  not the encapsulated packet.  So if you run tcpdump on a net with an
1172  IP Multicast tunnel, you cannot filter out the datagrams using the
1173  conventional syntax.  (You can filter away all the ip-in-ip traffic
1174  with "not ip proto 4".)
1175
1176- print-nfs.c: Keep pending rpc's in circular table. Add generic
1177  nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1178
1179- print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1180
1181- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1182  (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1183  Add && and || operators
1184
1185v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1186
1187- Fix bug with -c flag.
1188
1189v2.2 Fri May 22 17:19:41 PDT 1992
1190
1191- savefile.c: Remove hack that shouldn't have been exported. Add
1192  truncate checks.
1193
1194- Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1195  matches non-echo/reply ICMP packets.
1196
1197- Many improvements to filter code optimizer.
1198
1199- Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1200  so that protocol qualifications are allowed. For example, "ip broadcast"
1201  and "ether multicast" are valid filters.
1202
1203- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1204  Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1205  patches to netinet/if_loop.c.
1206
1207- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1208  Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1209
1210- Added EGP and OSPF printers, thanks to Jeffrey Honig.
1211
1212v2.1 Tue Jan 28 11:00:14 PST 1992
1213
1214- Internal release (never publically exported).
1215
1216v2.0.1 Sun Jan 26 21:10:10 PDT
1217
1218- Various byte ordering fixes.
1219
1220- Add truncation checks.
1221
1222- inet.c: Support BSD style SIOCGIFCONF.
1223
1224- nametoaddr.c: Handle multi addresses for single host.
1225
1226- optimize.c: Rewritten.
1227
1228- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1229  for broadcast nets.
1230
1231- print-atal.c: Fix an alignment bug (thanks to
1232  stanonik@nprdc.navy.mil) Add missing printf() argument.
1233
1234- print-bootp.c: First attempt at decoding the vendor buffer.
1235
1236- print-domain.c: Fix truncation checks.
1237
1238- print-icmp.c: Calculate length of packets from the ip header.
1239
1240- print-ip.c: Print frag id in decimal (so it's easier to match up
1241  with non-frags). Add support for ospf, egp and igmp.
1242
1243- print-nfs.c: Lots of changes.
1244
1245- print-ntp.c: Make some verbose output depend on -v.
1246
1247- print-snmp.c: New version from John LoVerso.
1248
1249- print-tcp.c: Print rfc1072 tcp options.
1250
1251- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1252  (microseconds) worth of precision. Fix uid bugs.
1253
1254- A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1255  With this option, you can create an architecture independent binary
1256  trace file in real time, without the overhead of the packet printer.
1257  At a later time, the packets can be filtered (again) and printed.
1258
1259- BSD is supported.  You must have BPF in your kernel.
1260  Since the filtering is now done in the kernel, fewer packets are
1261  dropped.  In fact, with BPF and the packet dumper option, a measly
1262  Sun 3/50 can keep up with a busy network.
1263
1264- Compressed SLIP packets can now be dumped, provided you use our
1265  SLIP software and BPF.  These packets are dumped as any other IP
1266  packet; the compressed headers are dumped with the '-e' option.
1267
1268- Machines with little-endian byte ordering are supported (thanks to
1269  Jeff Mogul).
1270
1271- Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1272
1273- IBM RT and Stanford Enetfilter support has been added by
1274  Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1275  both the vanilla Enetfilter interface, and the extended interface
1276  (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1277
1278- TFTP packets are now printed (requests only).
1279
1280- BOOTP packets are now printed.
1281
1282- SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1283
1284- Sparc architectures, including the Sparcstation-1, are now
1285  supported thanks to Steve McCanne and Craig Leres.
1286
1287- SunOS 4 is now supported thanks to Micky Liu of Columbia
1288  University (micky@cunixc.cc.columbia.edu).
1289
1290- IP options are now printed.
1291
1292- RIP packets are now printed.
1293
1294- There's a -v flag that prints out more information than the
1295  default (e.g., it will enable printing of IP ttl, tos and id)
1296  and -q flag that prints out less (e.g., it will disable
1297  interpretation of AppleTalk-in-UDP).
1298
1299- The grammar has undergone substantial changes (if you have an
1300  earlier version of tcpdump, you should re-read the manual
1301  entry).
1302
1303  The most useful change is the addition of an expression
1304  syntax that lets you filter on arbitrary fields or values in the
1305  packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1306  options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1307  packets.
1308
1309  The most painful change is that concatenation no longer means
1310  "and" -- e.g., you have to say "host foo and port bar" instead
1311  of "host foo port bar".  The up side to this down is that
1312  repeated qualifiers can be omitted, making most filter
1313  expressions shorter.  E.g., you can now say "ip host foo and
1314  (bar or baz)" to look at ip traffic between hosts foo and bar or
1315  between hosts foo and baz.  [The old way of saying this was "ip
1316  host foo and (ip host bar or ip host baz)".]
1317
1318v2.0 Sun Jan 13 12:20:40 PST 1991
1319
1320- Initial public release.
1321
