Thanks to Bruce Barnett 1025 (barnett@grymoire.crd.ge.com) 1026 1027- Fix rip printer to not print one more route than is actually in the 1028 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and 1029 Bill Fenner (fenner@parc.xerox.com) 1030 1031- Use autoconf endian detection since BYTE_ORDER isn't defined on all systems. 1032 1033- Fix dvmrp printer truncation checks and add a dvmrp probe printer. 1034 Thanks to Danny J. Mitzel (mitzel@ipsilon.com) 1035 1036- Rewrite ospf printer to improve truncation checks. 1037 1038- Don't parse tcp options past the EOL. As noted by David Sacerdote 1039 (davids@secnet.com). Also, check tcp options to make sure they ar 1040 actually in the tcp header (in addition to the normal truncation 1041 checks). Fix the SACK code to print the N blocks (instead of the 1042 first block N times). 1043 1044- Don't say really small UDP packets are truncated just because they 1045 aren't big enough to be a RPC. As noted by David Sacerdote. 1046 1047v3.2.1 Sun Jul 14 03:02:26 PDT 1996 1048 1049- Added rfc1716 icmp codes as suggested by Martin Fredriksson 1050 (martin@msp.se) 1051 1052- Print mtu for icmp unreach need frag packets.

Thanks to Jeffrey 1070 Mogul (mogul@pa.dec.com) 1071 1072- Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop. 1073 Thanks to John Hawkinson. 1074 1075- Added some more packet truncation checks. 1076 1077- On systems that have it, use sigset() instead of signal() since 1078 signal() has different semantics on these systems. 1079 1080- Fixed some more alignment problems on the alpha. 1081 1082- Add code to massage unprintable characters in the domain and ipx 1083 printers. Thanks to John Hawkinson. 1084 1085- Added explicit netmask support. Thanks to Steve Nuchia 1086 (steve@research.oknet.com) 1087 1088- Add "sca" keyword (for DEC cluster services) as suggested by Terry 1089 Kennedy (terry@spcvxa.spc.edu) 1090 1091- Add "atalk" keyword as suggested by John Hawkinson. 1092 1093- Added an igrp printer. Thanks to Francis Dupont 1094 (francis.dupont@inria.fr) 1095 1096- Print IPX net numbers in hex a la Novell Netware. Thanks to Terry 1097 Kennedy (terry@spcvxa.spc.edu) 1098 1099- Fixed snmp extended tag field parsing bug. Thanks to Pascal Hennequin 1100 (pascal.hennequin@hugo.int-evry.fr) 1101 1102- Added some ETHERTYPEs missing on some systems. 1103 1104- Added truncated packet macros and various checks. 1105 1106- Fixed endian problems with the DECnet printer. 1107 1108- Use $CC when checking gcc version. Thanks to Carl Lindberg 1109 (carl_lindberg@blacksmith.com) 1110 1111- Fixes for AIX (although this system is not yet supported). Thanks to 1112 John Hawkinson. 1113 1114- Fix bugs in the autoconf misaligned accesses code fragment. 1115 1116- Include sys/param.h to get BYTE_ORDER in a few places. Thanks to 1117 Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp) 1118 1119v3.2 Sun Jun 23 02:28:10 PDT 1996 1120 1121- Print new icmp unreachable codes as suggested by Martin Fredriksson 1122 (martin@msp.se). Also print code value when unknown for icmp redirect 1123 and time exceeded. 1124 1125- Fix an alignment endian bug in getname(). Thanks to John Hawkinson. 1126 1127- Define "new" domain record types if not found in arpa/nameserv.h. 1128 Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also 1129 fixed an endian bug when printing mx record and added some new record 1130 types. 1131 1132- Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com) 1133 1134- Added T/TCP options printing. As suggested by Richard Stevens 1135 (rstevens@noao.edu) 1136 1137- Use autoconf to detect architectures that can't handle misaligned 1138 accesses. 1139 1140v3.1 Thu Jun 13 20:59:32 PDT 1996 1141 1142- Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd 1143 and bind (as suggested by Charles Hannum). 1144 1145- Port to GNU autoconf. 1146 1147- Add support for printing DVMRP and PIM traffic thanks to 1148 Havard Eidnes (Havard.Eidnes@runit.sintef.no). 1149 1150- Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian 1151 define being referenced. Reported by Terry Kennedy. 1152 1153- Minor fixes to the man page thanks to Mark Andrews. 1154 1155- Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah 1156 (bmah@cs.berkeley.edu). 1157 1158- Added support for new dns types, thanks to Rainer Orth. 1159 1160- Fixed tftp_print() to print the block number for ACKs. 1161 1162- Document -dd and -ddd. Resulted from a bug report from Charlie Slater 1163 (cslater@imatek.com). 1164 1165- Check return status from malloc/calloc/etc. 1166 1167- Check return status from pcap_loop() so we can print an error and 1168 exit with a bad status if there were problems. 1169 1170- Bail if ip option length is <= 0. Resulted from a bug report from 1171 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au). 1172 1173- Print out a little more information for sun rpc packets. 1174 1175- Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu). 1176 1177- Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were 1178 wrong on little endian machines). 1179 1180- Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford 1181 (crawdad@fnal.gov). 1182 1183- Fix ntp_print() to not print garbage when the stratum is 1184 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com). 1185 1186- Rewrote tcp options printer code to check for truncation. Added 1187 selective acknowledgment case. 1188 1189- Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig 1190 (jch@bsdi.com) 1191 1192- Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one 1193 octet for the sa_family member. Thanks to Yoshitaka Tokugawa 1194 (toku@dit.co.jp) 1195 1196- Don't checksum ip header if we don't have all of it. Thanks to John 1197 Hawkinson (jhawk@mit.edu). 1198 1199- Print out hostnames if possible in egp printer. Thanks to Jeffrey 1200 Honig (jhc@bsdi.com) 1201 1202 1203v3.1a1 Wed May 3 19:21:11 PDT 1995 1204 1205- Include time.h when SVR4 is defined to avoid problems under Solaris 1206 2.3. 1207 1208- Fix etheraddr_string() in the ETHER_SERVICE to return the saved 1209 strings, not the local buffer. Thanks to Stefan Petri 1210 (petri@ibr.cs.tu-bs.de). 1211 1212- Detect when pcap raises the snaplen (e.g. with snit). Print a warning 1213 that the selected value was not used. Thanks to Pascal Hennequin 1214 (Pascal.Hennequin@hugo.int-evry.fr). 1215 1216- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin. 1217 1218- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu). 1219 1220v3.0.3 Sun Oct 1 18:35:00 GMT 1995 1221 1222- Although there never was a 3.0.3 release, the linux boys cleverly 1223 "released" one in late 1995. 1224 1225v3.0.2 Thu Apr 20 21:28:16 PDT 1995 1226 1227- Change configuration to not use gcc v2 flags with gcc v1. 1228 1229- Redo gmt2local() so that it works under BSDI (which seems to return 1230 an empty timezone struct from gettimeofday()). Based on report from 1231 Terry Kennedy (terry@spcvxa.spc.edu). 1232 1233- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based 1234 on report from Mark Andrews (mandrews@alias.com). 1235 1236- Don't pass cc flags to gcc. Resulted from a bug report from Rainer 1237 Orth (ro@techfak.uni-bielefeld.de). 1238 1239- Fixed printout of connection id for uncompressed tcp slip packets. 1240 Resulted from a bug report from Richard Stevens (rstevens@noao.edu). 1241 1242- Hack around deficiency in Ultrix's make. 1243 1244- Add ETHERTYPE_TRAIL define which is missing from irix5. 1245 1246v3.0.1 Wed Aug 31 22:42:26 PDT 1994 1247 1248- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4. 1249 1250v3.0 Mon Jun 20 19:23:27 PDT 1994 1251 1252- Added support for printing tcp option timestamps thanks to 1253 Mark Andrews (mandrews@alias.com). 1254 1255- Reorganize protocol dumpers to take const pointers to packets so they 1256 never change the contents (i.e., they used to do endian conversions 1257 in place). Previously, whenever more than one pass was taken over 1258 the packet, the packet contents would be dumped incorrectly (i.e., 1259 the output form -x would be wrong on little endian machines because 1260 the protocol dumpers would modify the data). Thanks to Charles Hannum 1261 (mycroft@gnu.ai.mit.edu) for reporting this problem. 1262 1263- Added support for decnet protocol dumping thanks to Jeff Mogul 1264 (mogul@pa.dec.com). 1265 1266- Fix bug that caused length of packet to be incorrectly printed 1267 (off by ether header size) for unknown ethernet types thanks 1268 to Greg Miller (gmiller@kayak.mitre.org). 1269 1270- Added support for IPX protocol dumping thanks to Brad Parker 1271 (brad@fcr.com). 1272 1273- Added check to verify IP header checksum under -v thanks to 1274 Brad Parker (brad@fcr.com). 1275 1276- Move packet capture code to new libpcap library (which is 1277 packaged separately). 1278 1279- Prototype everything and assume an ansi compiler. 1280 1281- print-arp.c: Print hardware ethernet addresses if they're not 1282 what we expect. 1283 1284- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. 1285 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). 1286 1287- print-fddi.c: Improvements. Thanks to Jeffrey Mogul 1288 (mogul@pa.dec.com). 1289 1290- print-icmp.c: Byte swap netmask before printing. Thanks to 1291 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. 1292 1293- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. 1294 By default, only the inner packet is dumped, appended with the token 1295 "(encap)". Under -v, both the inner and output packets are dumped 1296 (on the same line). Note that the filter applies to the original packet, 1297 not the encapsulated packet. So if you run tcpdump on a net with an 1298 IP Multicast tunnel, you cannot filter out the datagrams using the 1299 conventional syntax. (You can filter away all the ip-in-ip traffic 1300 with "not ip proto 4".) 1301 1302- print-nfs.c: Keep pending rpc's in circular table. Add generic 1303 nfs header and remove os dependences. Thanks to Jeffrey Mogul. 1304 1305- print-ospf.c: Improvements. Thanks to Jeffrey Mogul. 1306 1307- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" 1308 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords 1309 Add && and || operators 1310 1311v2.2.1 Tue Jun 6 17:57:22 PDT 1992 1312 1313- Fix bug with -c flag. 1314 1315v2.2 Fri May 22 17:19:41 PDT 1992 1316 1317- savefile.c: Remove hack that shouldn't have been exported. Add 1318 truncate checks. 1319 1320- Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' 1321 matches non-echo/reply ICMP packets. 1322 1323- Many improvements to filter code optimizer. 1324 1325- Added 'multicast' keyword and extended the 'broadcast' keyword can now be 1326 so that protocol qualifications are allowed. For example, "ip broadcast" 1327 and "ether multicast" are valid filters. 1328 1329- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). 1330 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel 1331 patches to netinet/if_loop.c. 1332 1333- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. 1334 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. 1335 1336- Added EGP and OSPF printers, thanks to Jeffrey Honig. 1337 1338v2.1 Tue Jan 28 11:00:14 PST 1992 1339 1340- Internal release (never publically exported). 1341 1342v2.0.1 Sun Jan 26 21:10:10 PDT 1343 1344- Various byte ordering fixes. 1345 1346- Add truncation checks. 1347 1348- inet.c: Support BSD style SIOCGIFCONF. 1349 1350- nametoaddr.c: Handle multi addresses for single host. 1351 1352- optimize.c: Rewritten. 1353 1354- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous 1355 for broadcast nets. 1356 1357- print-atal.c: Fix an alignment bug (thanks to 1358 stanonik@nprdc.navy.mil) Add missing printf() argument. 1359 1360- print-bootp.c: First attempt at decoding the vendor buffer. 1361 1362- print-domain.c: Fix truncation checks. 1363 1364- print-icmp.c: Calculate length of packets from the ip header. 1365 1366- print-ip.c: Print frag id in decimal (so it's easier to match up 1367 with non-frags). Add support for ospf, egp and igmp. 1368 1369- print-nfs.c: Lots of changes. 1370 1371- print-ntp.c: Make some verbose output depend on -v. 1372 1373- print-snmp.c: New version from John LoVerso. 1374 1375- print-tcp.c: Print rfc1072 tcp options. 1376 1377- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits 1378 (microseconds) worth of precision. Fix uid bugs. 1379 1380- A packet dumper has been added (thanks to Jeff Mogul of DECWRL). 1381 With this option, you can create an architecture independent binary 1382 trace file in real time, without the overhead of the packet printer. 1383 At a later time, the packets can be filtered (again) and printed. 1384 1385- BSD is supported. You must have BPF in your kernel. 1386 Since the filtering is now done in the kernel, fewer packets are 1387 dropped. In fact, with BPF and the packet dumper option, a measly 1388 Sun 3/50 can keep up with a busy network. 1389 1390- Compressed SLIP packets can now be dumped, provided you use our 1391 SLIP software and BPF. These packets are dumped as any other IP 1392 packet; the compressed headers are dumped with the '-e' option. 1393 1394- Machines with little-endian byte ordering are supported (thanks to 1395 Jeff Mogul). 1396 1397- Ultrix 4.0 is supported (also thanks to Jeff Mogul). 1398 1399- IBM RT and Stanford Enetfilter support has been added by 1400 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under 1401 both the vanilla Enetfilter interface, and the extended interface 1402 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. 1403 1404- TFTP packets are now printed (requests only). 1405 1406- BOOTP packets are now printed. 1407 1408- SNMP packets are now printed. (thanks to John LoVerso of Xylogics). 1409 1410- Sparc architectures, including the Sparcstation-1, are now 1411 supported thanks to Steve McCanne and Craig Leres. 1412 1413- SunOS 4 is now supported thanks to Micky Liu of Columbia 1414 University (micky@cunixc.cc.columbia.edu). 1415 1416- IP options are now printed. 1417 1418- RIP packets are now printed. 1419 1420- There's a -v flag that prints out more information than the 1421 default (e.g., it will enable printing of IP ttl, tos and id) 1422 and -q flag that prints out less (e.g., it will disable 1423 interpretation of AppleTalk-in-UDP). 1424 1425- The grammar has undergone substantial changes (if you have an 1426 earlier version of tcpdump, you should re-read the manual 1427 entry). 1428 1429 The most useful change is the addition of an expression 1430 syntax that lets you filter on arbitrary fields or values in the 1431 packet. E.g., "ip[0] > 0x45" would print only packets with IP 1432 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN 1433 packets. 1434 1435 The most painful change is that concatenation no longer means 1436 "and" -- e.g., you have to say "host foo and port bar" instead 1437 of "host foo port bar". The up side to this down is that 1438 repeated qualifiers can be omitted, making most filter 1439 expressions shorter. E.g., you can now say "ip host foo and 1440 (bar or baz)" to look at ip traffic between hosts foo and bar or 1441 between hosts foo and baz. [The old way of saying this was "ip 1442 host foo and (ip host bar or ip host baz)".] 1443 1444v2.0 Sun Jan 13 12:20:40 PST 1991 1445 1446- Initial public release. 1447
