1081 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
1083 - Rewrote tcp options printer code to check for truncation. Added
1084 selective acknowledgment case.
1086 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
1089 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1090 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1093 - Don't checksum ip header if we don't have all of it. Thanks to John
1094 Hawkinson (jhawk@mit.edu).
1096 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1097 Honig (jhc@bsdi.com)
1100 v3.1a1 Wed May 3 19:21:11 PDT 1995
1102 - Include time.h when SVR4 is defined to avoid problems under Solaris
1105 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1106 strings, not the local buffer. Thanks to Stefan Petri
1107 (petri@ibr.cs.tu-bs.de).
1109 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1110 that the selected value was not used. Thanks to Pascal Hennequin
1111 (Pascal.Hennequin@hugo.int-evry.fr).
1113 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1115 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1117 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1119 - Although there never was a 3.0.3 release, the linux boys cleverly
1120 "released" one in late 1995.
1122 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1124 - Change configuration to not use gcc v2 flags with gcc v1.
1126 - Redo gmt2local() so that it works under BSDI (which seems to return
1127 an empty timezone struct from gettimeofday()). Based on report from
1128 Terry Kennedy (terry@spcvxa.spc.edu).
1130 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1131 on report from Mark Andrews (mandrews@alias.com).
1133 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1134 Orth (ro@techfak.uni-bielefeld.de).
1136 - Fixed printout of connection id for uncompressed tcp slip packets.
1137 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1139 - Hack around deficiency in Ultrix's make.
1141 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1143 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1145 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1147 v3.0 Mon Jun 20 19:23:27 PDT 1994
1149 - Added support for printing tcp option timestamps thanks to
1150 Mark Andrews (mandrews@alias.com).
1152 - Reorganize protocol dumpers to take const pointers to packets so they
1153 never change the contents (i.e., they used to do endian conversions
1154 in place). Previously, whenever more than one pass was taken over
1155 the packet, the packet contents would be dumped incorrectly (i.e.,
1156 the output form -x would be wrong on little endian machines because
1157 the protocol dumpers would modify the data). Thanks to Charles Hannum
1158 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1160 - Added support for decnet protocol dumping thanks to Jeff Mogul
1163 - Fix bug that caused length of packet to be incorrectly printed
1164 (off by ether header size) for unknown ethernet types thanks
1165 to Greg Miller (gmiller@kayak.mitre.org).
1167 - Added support for IPX protocol dumping thanks to Brad Parker
1170 - Added check to verify IP header checksum under -v thanks to
1171 Brad Parker (brad@fcr.com).
1173 - Move packet capture code to new libpcap library (which is
1174 packaged separately).
1176 - Prototype everything and assume an ansi compiler.
1178 - print-arp.c: Print hardware ethernet addresses if they're not
1181 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1182 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1184 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1187 - print-icmp.c: Byte swap netmask before printing. Thanks to
1188 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1190 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1191 By default, only the inner packet is dumped, appended with the token
1192 "(encap)". Under -v, both the inner and output packets are dumped
1193 (on the same line). Note that the filter applies to the original packet,
1194 not the encapsulated packet. So if you run tcpdump on a net with an
1195 IP Multicast tunnel, you cannot filter out the datagrams using the
1196 conventional syntax. (You can filter away all the ip-in-ip traffic
1197 with "not ip proto 4".)
1199 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1200 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1202 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1204 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1205 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1206 Add && and || operators
1208 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1210 - Fix bug with -c flag.
1212 v2.2 Fri May 22 17:19:41 PDT 1992
1214 - savefile.c: Remove hack that shouldn't have been exported. Add
1217 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1218 matches non-echo/reply ICMP packets.
1220 - Many improvements to filter code optimizer.
1222 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1223 so that protocol qualifications are allowed. For example, "ip broadcast"
1224 and "ether multicast" are valid filters.
1226 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1227 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1228 patches to netinet/if_loop.c.
1230 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1231 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1233 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1235 v2.1 Tue Jan 28 11:00:14 PST 1992
1237 - Internal release (never publically exported).
1239 v2.0.1 Sun Jan 26 21:10:10 PDT
1241 - Various byte ordering fixes.
1243 - Add truncation checks.
1245 - inet.c: Support BSD style SIOCGIFCONF.
1247 - nametoaddr.c: Handle multi addresses for single host.
1249 - optimize.c: Rewritten.
1251 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1254 - print-atal.c: Fix an alignment bug (thanks to
1255 stanonik@nprdc.navy.mil) Add missing printf() argument.
1257 - print-bootp.c: First attempt at decoding the vendor buffer.
1259 - print-domain.c: Fix truncation checks.
1261 - print-icmp.c: Calculate length of packets from the ip header.
1263 - print-ip.c: Print frag id in decimal (so it's easier to match up
1264 with non-frags). Add support for ospf, egp and igmp.
1266 - print-nfs.c: Lots of changes.
1268 - print-ntp.c: Make some verbose output depend on -v.
1270 - print-snmp.c: New version from John LoVerso.
1272 - print-tcp.c: Print rfc1072 tcp options.
1274 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1275 (microseconds) worth of precision. Fix uid bugs.
1277 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1278 With this option, you can create an architecture independent binary
1279 trace file in real time, without the overhead of the packet printer.
1280 At a later time, the packets can be filtered (again) and printed.
1282 - BSD is supported. You must have BPF in your kernel.
1283 Since the filtering is now done in the kernel, fewer packets are
1284 dropped. In fact, with BPF and the packet dumper option, a measly
1285 Sun 3/50 can keep up with a busy network.
1287 - Compressed SLIP packets can now be dumped, provided you use our
1288 SLIP software and BPF. These packets are dumped as any other IP
1289 packet; the compressed headers are dumped with the '-e' option.
1291 - Machines with little-endian byte ordering are supported (thanks to
1294 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1296 - IBM RT and Stanford Enetfilter support has been added by
1297 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1298 both the vanilla Enetfilter interface, and the extended interface
1299 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1301 - TFTP packets are now printed (requests only).
1303 - BOOTP packets are now printed.
1305 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1307 - Sparc architectures, including the Sparcstation-1, are now
1308 supported thanks to Steve McCanne and Craig Leres.
1310 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1311 University (micky@cunixc.cc.columbia.edu).
1313 - IP options are now printed.
1315 - RIP packets are now printed.
1317 - There's a -v flag that prints out more information than the
1318 default (e.g., it will enable printing of IP ttl, tos and id)
1319 and -q flag that prints out less (e.g., it will disable
1320 interpretation of AppleTalk-in-UDP).
1322 - The grammar has undergone substantial changes (if you have an
1323 earlier version of tcpdump, you should re-read the manual
1326 The most useful change is the addition of an expression
1327 syntax that lets you filter on arbitrary fields or values in the
1328 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1329 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1332 The most painful change is that concatenation no longer means
1333 "and" -- e.g., you have to say "host foo and port bar" instead
1334 of "host foo port bar". The up side to this down is that
1335 repeated qualifiers can be omitted, making most filter
1336 expressions shorter. E.g., you can now say "ip host foo and
1337 (bar or baz)" to look at ip traffic between hosts foo and bar or
1338 between hosts foo and baz. [The old way of saying this was "ip
1339 host foo and (ip host bar or ip host baz)".]
1341 v2.0 Sun Jan 13 12:20:40 PST 1991
1343 - Initial public release.
