1079 - Bail if ip option length is <= 0. Resulted from a bug report from
1080 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1082 - Print out a little more information for sun rpc packets.
1084 - Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1086 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1087 wrong on little endian machines).
1089 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1092 - Fix ntp_print() to not print garbage when the stratum is
1093 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
1095 - Rewrote tcp options printer code to check for truncation. Added
1096 selective acknowledgment case.
1098 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
1101 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1102 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1105 - Don't checksum ip header if we don't have all of it. Thanks to John
1106 Hawkinson (jhawk@mit.edu).
1108 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1109 Honig (jhc@bsdi.com)
1112 v3.1a1 Wed May 3 19:21:11 PDT 1995
1114 - Include time.h when SVR4 is defined to avoid problems under Solaris
1117 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1118 strings, not the local buffer. Thanks to Stefan Petri
1119 (petri@ibr.cs.tu-bs.de).
1121 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1122 that the selected value was not used. Thanks to Pascal Hennequin
1123 (Pascal.Hennequin@hugo.int-evry.fr).
1125 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1127 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1129 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1131 - Although there never was a 3.0.3 release, the linux boys cleverly
1132 "released" one in late 1995.
1134 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1136 - Change configuration to not use gcc v2 flags with gcc v1.
1138 - Redo gmt2local() so that it works under BSDI (which seems to return
1139 an empty timezone struct from gettimeofday()). Based on report from
1140 Terry Kennedy (terry@spcvxa.spc.edu).
1142 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1143 on report from Mark Andrews (mandrews@alias.com).
1145 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1146 Orth (ro@techfak.uni-bielefeld.de).
1148 - Fixed printout of connection id for uncompressed tcp slip packets.
1149 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1151 - Hack around deficiency in Ultrix's make.
1153 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1155 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1157 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1159 v3.0 Mon Jun 20 19:23:27 PDT 1994
1161 - Added support for printing tcp option timestamps thanks to
1162 Mark Andrews (mandrews@alias.com).
1164 - Reorganize protocol dumpers to take const pointers to packets so they
1165 never change the contents (i.e., they used to do endian conversions
1166 in place). Previously, whenever more than one pass was taken over
1167 the packet, the packet contents would be dumped incorrectly (i.e.,
1168 the output form -x would be wrong on little endian machines because
1169 the protocol dumpers would modify the data). Thanks to Charles Hannum
1170 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1172 - Added support for decnet protocol dumping thanks to Jeff Mogul
1175 - Fix bug that caused length of packet to be incorrectly printed
1176 (off by ether header size) for unknown ethernet types thanks
1177 to Greg Miller (gmiller@kayak.mitre.org).
1179 - Added support for IPX protocol dumping thanks to Brad Parker
1182 - Added check to verify IP header checksum under -v thanks to
1183 Brad Parker (brad@fcr.com).
1185 - Move packet capture code to new libpcap library (which is
1186 packaged separately).
1188 - Prototype everything and assume an ansi compiler.
1190 - print-arp.c: Print hardware ethernet addresses if they're not
1193 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1194 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1196 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1199 - print-icmp.c: Byte swap netmask before printing. Thanks to
1200 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1202 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1203 By default, only the inner packet is dumped, appended with the token
1204 "(encap)". Under -v, both the inner and output packets are dumped
1205 (on the same line). Note that the filter applies to the original packet,
1206 not the encapsulated packet. So if you run tcpdump on a net with an
1207 IP Multicast tunnel, you cannot filter out the datagrams using the
1208 conventional syntax. (You can filter away all the ip-in-ip traffic
1209 with "not ip proto 4".)
1211 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1212 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1214 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1216 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1217 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1218 Add && and || operators
1220 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1222 - Fix bug with -c flag.
1224 v2.2 Fri May 22 17:19:41 PDT 1992
1226 - savefile.c: Remove hack that shouldn't have been exported. Add
1229 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1230 matches non-echo/reply ICMP packets.
1232 - Many improvements to filter code optimizer.
1234 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1235 so that protocol qualifications are allowed. For example, "ip broadcast"
1236 and "ether multicast" are valid filters.
1238 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1239 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1240 patches to netinet/if_loop.c.
1242 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1243 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1245 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1247 v2.1 Tue Jan 28 11:00:14 PST 1992
1249 - Internal release (never publically exported).
1251 v2.0.1 Sun Jan 26 21:10:10 PDT
1253 - Various byte ordering fixes.
1255 - Add truncation checks.
1257 - inet.c: Support BSD style SIOCGIFCONF.
1259 - nametoaddr.c: Handle multi addresses for single host.
1261 - optimize.c: Rewritten.
1263 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1266 - print-atal.c: Fix an alignment bug (thanks to
1267 stanonik@nprdc.navy.mil) Add missing printf() argument.
1269 - print-bootp.c: First attempt at decoding the vendor buffer.
1271 - print-domain.c: Fix truncation checks.
1273 - print-icmp.c: Calculate length of packets from the ip header.
1275 - print-ip.c: Print frag id in decimal (so it's easier to match up
1276 with non-frags). Add support for ospf, egp and igmp.
1278 - print-nfs.c: Lots of changes.
1280 - print-ntp.c: Make some verbose output depend on -v.
1282 - print-snmp.c: New version from John LoVerso.
1284 - print-tcp.c: Print rfc1072 tcp options.
1286 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1287 (microseconds) worth of precision. Fix uid bugs.
1289 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1290 With this option, you can create an architecture independent binary
1291 trace file in real time, without the overhead of the packet printer.
1292 At a later time, the packets can be filtered (again) and printed.
1294 - BSD is supported. You must have BPF in your kernel.
1295 Since the filtering is now done in the kernel, fewer packets are
1296 dropped. In fact, with BPF and the packet dumper option, a measly
1297 Sun 3/50 can keep up with a busy network.
1299 - Compressed SLIP packets can now be dumped, provided you use our
1300 SLIP software and BPF. These packets are dumped as any other IP
1301 packet; the compressed headers are dumped with the '-e' option.
1303 - Machines with little-endian byte ordering are supported (thanks to
1306 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1308 - IBM RT and Stanford Enetfilter support has been added by
1309 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1310 both the vanilla Enetfilter interface, and the extended interface
1311 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1313 - TFTP packets are now printed (requests only).
1315 - BOOTP packets are now printed.
1317 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1319 - Sparc architectures, including the Sparcstation-1, are now
1320 supported thanks to Steve McCanne and Craig Leres.
1322 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1323 University (micky@cunixc.cc.columbia.edu).
1325 - IP options are now printed.
1327 - RIP packets are now printed.
1329 - There's a -v flag that prints out more information than the
1330 default (e.g., it will enable printing of IP ttl, tos and id)
1331 and -q flag that prints out less (e.g., it will disable
1332 interpretation of AppleTalk-in-UDP).
1334 - The grammar has undergone substantial changes (if you have an
1335 earlier version of tcpdump, you should re-read the manual
1338 The most useful change is the addition of an expression
1339 syntax that lets you filter on arbitrary fields or values in the
1340 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1341 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1344 The most painful change is that concatenation no longer means
1345 "and" -- e.g., you have to say "host foo and port bar" instead
1346 of "host foo port bar". The up side to this down is that
1347 repeated qualifiers can be omitted, making most filter
1348 expressions shorter. E.g., you can now say "ip host foo and
1349 (bar or baz)" to look at ip traffic between hosts foo and bar or
1350 between hosts foo and baz. [The old way of saying this was "ip
1351 host foo and (ip host bar or ip host baz)".]
1353 v2.0 Sun Jan 13 12:20:40 PST 1991
1355 - Initial public release.
