1087 Honig (jhc@bsdi.com)
1090 v3.1a1 Wed May 3 19:21:11 PDT 1995
1092 - Include time.h when SVR4 is defined to avoid problems under Solaris
1095 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1096 strings, not the local buffer. Thanks to Stefan Petri
1097 (petri@ibr.cs.tu-bs.de).
1099 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1100 that the selected value was not used. Thanks to Pascal Hennequin
1101 (Pascal.Hennequin@hugo.int-evry.fr).
1103 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1105 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1107 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1109 - Although there never was a 3.0.3 release, the linux boys cleverly
1110 "released" one in late 1995.
1112 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1114 - Change configuration to not use gcc v2 flags with gcc v1.
1116 - Redo gmt2local() so that it works under BSDI (which seems to return
1117 an empty timezone struct from gettimeofday()). Based on report from
1118 Terry Kennedy (terry@spcvxa.spc.edu).
1120 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1121 on report from Mark Andrews (mandrews@alias.com).
1123 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1124 Orth (ro@techfak.uni-bielefeld.de).
1126 - Fixed printout of connection id for uncompressed tcp slip packets.
1127 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1129 - Hack around deficiency in Ultrix's make.
1131 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1133 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1135 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1137 v3.0 Mon Jun 20 19:23:27 PDT 1994
1139 - Added support for printing tcp option timestamps thanks to
1140 Mark Andrews (mandrews@alias.com).
1142 - Reorganize protocol dumpers to take const pointers to packets so they
1143 never change the contents (i.e., they used to do endian conversions
1144 in place). Previously, whenever more than one pass was taken over
1145 the packet, the packet contents would be dumped incorrectly (i.e.,
1146 the output form -x would be wrong on little endian machines because
1147 the protocol dumpers would modify the data). Thanks to Charles Hannum
1148 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1150 - Added support for decnet protocol dumping thanks to Jeff Mogul
1153 - Fix bug that caused length of packet to be incorrectly printed
1154 (off by ether header size) for unknown ethernet types thanks
1155 to Greg Miller (gmiller@kayak.mitre.org).
1157 - Added support for IPX protocol dumping thanks to Brad Parker
1160 - Added check to verify IP header checksum under -v thanks to
1161 Brad Parker (brad@fcr.com).
1163 - Move packet capture code to new libpcap library (which is
1164 packaged separately).
1166 - Prototype everything and assume an ansi compiler.
1168 - print-arp.c: Print hardware ethernet addresses if they're not
1171 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1172 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1174 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1177 - print-icmp.c: Byte swap netmask before printing. Thanks to
1178 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1180 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1181 By default, only the inner packet is dumped, appended with the token
1182 "(encap)". Under -v, both the inner and output packets are dumped
1183 (on the same line). Note that the filter applies to the original packet,
1184 not the encapsulated packet. So if you run tcpdump on a net with an
1185 IP Multicast tunnel, you cannot filter out the datagrams using the
1186 conventional syntax. (You can filter away all the ip-in-ip traffic
1187 with "not ip proto 4".)
1189 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1190 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1192 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1194 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1195 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1196 Add && and || operators
1198 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1200 - Fix bug with -c flag.
1202 v2.2 Fri May 22 17:19:41 PDT 1992
1204 - savefile.c: Remove hack that shouldn't have been exported. Add
1207 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1208 matches non-echo/reply ICMP packets.
1210 - Many improvements to filter code optimizer.
1212 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1213 so that protocol qualifications are allowed. For example, "ip broadcast"
1214 and "ether multicast" are valid filters.
1216 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1217 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1218 patches to netinet/if_loop.c.
1220 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1221 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1223 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1225 v2.1 Tue Jan 28 11:00:14 PST 1992
1227 - Internal release (never publically exported).
1229 v2.0.1 Sun Jan 26 21:10:10 PDT
1231 - Various byte ordering fixes.
1233 - Add truncation checks.
1235 - inet.c: Support BSD style SIOCGIFCONF.
1237 - nametoaddr.c: Handle multi addresses for single host.
1239 - optimize.c: Rewritten.
1241 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1244 - print-atal.c: Fix an alignment bug (thanks to
1245 stanonik@nprdc.navy.mil) Add missing printf() argument.
1247 - print-bootp.c: First attempt at decoding the vendor buffer.
1249 - print-domain.c: Fix truncation checks.
1251 - print-icmp.c: Calculate length of packets from the ip header.
1253 - print-ip.c: Print frag id in decimal (so it's easier to match up
1254 with non-frags). Add support for ospf, egp and igmp.
1256 - print-nfs.c: Lots of changes.
1258 - print-ntp.c: Make some verbose output depend on -v.
1260 - print-snmp.c: New version from John LoVerso.
1262 - print-tcp.c: Print rfc1072 tcp options.
1264 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1265 (microseconds) worth of precision. Fix uid bugs.
1267 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1268 With this option, you can create an architecture independent binary
1269 trace file in real time, without the overhead of the packet printer.
1270 At a later time, the packets can be filtered (again) and printed.
1272 - BSD is supported. You must have BPF in your kernel.
1273 Since the filtering is now done in the kernel, fewer packets are
1274 dropped. In fact, with BPF and the packet dumper option, a measly
1275 Sun 3/50 can keep up with a busy network.
1277 - Compressed SLIP packets can now be dumped, provided you use our
1278 SLIP software and BPF. These packets are dumped as any other IP
1279 packet; the compressed headers are dumped with the '-e' option.
1281 - Machines with little-endian byte ordering are supported (thanks to
1284 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1286 - IBM RT and Stanford Enetfilter support has been added by
1287 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1288 both the vanilla Enetfilter interface, and the extended interface
1289 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1291 - TFTP packets are now printed (requests only).
1293 - BOOTP packets are now printed.
1295 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1297 - Sparc architectures, including the Sparcstation-1, are now
1298 supported thanks to Steve McCanne and Craig Leres.
1300 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1301 University (micky@cunixc.cc.columbia.edu).
1303 - IP options are now printed.
1305 - RIP packets are now printed.
1307 - There's a -v flag that prints out more information than the
1308 default (e.g., it will enable printing of IP ttl, tos and id)
1309 and -q flag that prints out less (e.g., it will disable
1310 interpretation of AppleTalk-in-UDP).
1312 - The grammar has undergone substantial changes (if you have an
1313 earlier version of tcpdump, you should re-read the manual
1316 The most useful change is the addition of an expression
1317 syntax that lets you filter on arbitrary fields or values in the
1318 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1319 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1322 The most painful change is that concatenation no longer means
1323 "and" -- e.g., you have to say "host foo and port bar" instead
1324 of "host foo port bar". The up side to this down is that
1325 repeated qualifiers can be omitted, making most filter
1326 expressions shorter. E.g., you can now say "ip host foo and
1327 (bar or baz)" to look at ip traffic between hosts foo and bar or
1328 between hosts foo and baz. [The old way of saying this was "ip
1329 host foo and (ip host bar or ip host baz)".]
1331 v2.0 Sun Jan 13 12:20:40 PST 1991
1333 - Initial public release.
