Thanks to Jeffrey 1473 Honig (jhc@bsdi.com) 1474 1475 1476v3.1a1 Wed May 3 19:21:11 PDT 1995 1477 1478- Include time.h when SVR4 is defined to avoid problems under Solaris 1479 2.3. 1480 1481- Fix etheraddr_string() in the ETHER_SERVICE to return the saved 1482 strings, not the local buffer. Thanks to Stefan Petri 1483 (petri@ibr.cs.tu-bs.de). 1484 1485- Detect when pcap raises the snaplen (e.g. with snit). Print a warning 1486 that the selected value was not used. Thanks to Pascal Hennequin 1487 (Pascal.Hennequin@hugo.int-evry.fr). 1488 1489- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin. 1490 1491- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu). 1492 1493v3.0.3 Sun Oct 1 18:35:00 GMT 1995 1494 1495- Although there never was a 3.0.3 release, the linux boys cleverly 1496 "released" one in late 1995. 1497 1498v3.0.2 Thu Apr 20 21:28:16 PDT 1995 1499 1500- Change configuration to not use gcc v2 flags with gcc v1. 1501 1502- Redo gmt2local() so that it works under BSDI (which seems to return 1503 an empty timezone struct from gettimeofday()). Based on report from 1504 Terry Kennedy (terry@spcvxa.spc.edu). 1505 1506- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based 1507 on report from Mark Andrews (mandrews@alias.com). 1508 1509- Don't pass cc flags to gcc. Resulted from a bug report from Rainer 1510 Orth (ro@techfak.uni-bielefeld.de). 1511 1512- Fixed printout of connection id for uncompressed tcp slip packets. 1513 Resulted from a bug report from Richard Stevens (rstevens@noao.edu). 1514 1515- Hack around deficiency in Ultrix's make. 1516 1517- Add ETHERTYPE_TRAIL define which is missing from irix5. 1518 1519v3.0.1 Wed Aug 31 22:42:26 PDT 1994 1520 1521- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4. 1522 1523v3.0 Mon Jun 20 19:23:27 PDT 1994 1524 1525- Added support for printing tcp option timestamps thanks to 1526 Mark Andrews (mandrews@alias.com). 1527 1528- Reorganize protocol dumpers to take const pointers to packets so they 1529 never change the contents (i.e., they used to do endian conversions 1530 in place). Previously, whenever more than one pass was taken over 1531 the packet, the packet contents would be dumped incorrectly (i.e., 1532 the output form -x would be wrong on little endian machines because 1533 the protocol dumpers would modify the data). Thanks to Charles Hannum 1534 (mycroft@gnu.ai.mit.edu) for reporting this problem. 1535 1536- Added support for decnet protocol dumping thanks to Jeff Mogul 1537 (mogul@pa.dec.com). 1538 1539- Fix bug that caused length of packet to be incorrectly printed 1540 (off by ether header size) for unknown ethernet types thanks 1541 to Greg Miller (gmiller@kayak.mitre.org). 1542 1543- Added support for IPX protocol dumping thanks to Brad Parker 1544 (brad@fcr.com). 1545 1546- Added check to verify IP header checksum under -v thanks to 1547 Brad Parker (brad@fcr.com). 1548 1549- Move packet capture code to new libpcap library (which is 1550 packaged separately). 1551 1552- Prototype everything and assume an ansi compiler. 1553 1554- print-arp.c: Print hardware ethernet addresses if they're not 1555 what we expect. 1556 1557- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. 1558 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). 1559 1560- print-fddi.c: Improvements. Thanks to Jeffrey Mogul 1561 (mogul@pa.dec.com). 1562 1563- print-icmp.c: Byte swap netmask before printing. Thanks to 1564 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. 1565 1566- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. 1567 By default, only the inner packet is dumped, appended with the token 1568 "(encap)". Under -v, both the inner and output packets are dumped 1569 (on the same line). Note that the filter applies to the original packet, 1570 not the encapsulated packet. So if you run tcpdump on a net with an 1571 IP Multicast tunnel, you cannot filter out the datagrams using the 1572 conventional syntax. (You can filter away all the ip-in-ip traffic 1573 with "not ip proto 4".) 1574 1575- print-nfs.c: Keep pending rpc's in circular table. Add generic 1576 nfs header and remove os dependences. Thanks to Jeffrey Mogul. 1577 1578- print-ospf.c: Improvements. Thanks to Jeffrey Mogul. 1579 1580- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" 1581 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords 1582 Add && and || operators 1583 1584v2.2.1 Tue Jun 6 17:57:22 PDT 1992 1585 1586- Fix bug with -c flag. 1587 1588v2.2 Fri May 22 17:19:41 PDT 1992 1589 1590- savefile.c: Remove hack that shouldn't have been exported. Add 1591 truncate checks. 1592 1593- Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' 1594 matches non-echo/reply ICMP packets. 1595 1596- Many improvements to filter code optimizer. 1597 1598- Added 'multicast' keyword and extended the 'broadcast' keyword can now be 1599 so that protocol qualifications are allowed. For example, "ip broadcast" 1600 and "ether multicast" are valid filters. 1601 1602- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). 1603 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel 1604 patches to netinet/if_loop.c. 1605 1606- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. 1607 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. 1608 1609- Added EGP and OSPF printers, thanks to Jeffrey Honig. 1610 1611v2.1 Tue Jan 28 11:00:14 PST 1992 1612 1613- Internal release (never publicly exported). 1614 1615v2.0.1 Sun Jan 26 21:10:10 PDT 1616 1617- Various byte ordering fixes. 1618 1619- Add truncation checks. 1620 1621- inet.c: Support BSD style SIOCGIFCONF. 1622 1623- nametoaddr.c: Handle multi addresses for single host. 1624 1625- optimize.c: Rewritten. 1626 1627- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous 1628 for broadcast nets. 1629 1630- print-atal.c: Fix an alignment bug (thanks to 1631 stanonik@nprdc.navy.mil) Add missing printf() argument. 1632 1633- print-bootp.c: First attempt at decoding the vendor buffer. 1634 1635- print-domain.c: Fix truncation checks. 1636 1637- print-icmp.c: Calculate length of packets from the ip header. 1638 1639- print-ip.c: Print frag id in decimal (so it's easier to match up 1640 with non-frags). Add support for ospf, egp and igmp. 1641 1642- print-nfs.c: Lots of changes. 1643 1644- print-ntp.c: Make some verbose output depend on -v. 1645 1646- print-snmp.c: New version from John LoVerso. 1647 1648- print-tcp.c: Print rfc1072 tcp options. 1649 1650- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits 1651 (microseconds) worth of precision. Fix uid bugs. 1652 1653- A packet dumper has been added (thanks to Jeff Mogul of DECWRL). 1654 With this option, you can create an architecture independent binary 1655 trace file in real time, without the overhead of the packet printer. 1656 At a later time, the packets can be filtered (again) and printed. 1657 1658- BSD is supported. You must have BPF in your kernel. 1659 Since the filtering is now done in the kernel, fewer packets are 1660 dropped. In fact, with BPF and the packet dumper option, a measly 1661 Sun 3/50 can keep up with a busy network. 1662 1663- Compressed SLIP packets can now be dumped, provided you use our 1664 SLIP software and BPF. These packets are dumped as any other IP 1665 packet; the compressed headers are dumped with the '-e' option. 1666 1667- Machines with little-endian byte ordering are supported (thanks to 1668 Jeff Mogul). 1669 1670- Ultrix 4.0 is supported (also thanks to Jeff Mogul). 1671 1672- IBM RT and Stanford Enetfilter support has been added by 1673 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under 1674 both the vanilla Enetfilter interface, and the extended interface 1675 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. 1676 1677- TFTP packets are now printed (requests only). 1678 1679- BOOTP packets are now printed. 1680 1681- SNMP packets are now printed. (thanks to John LoVerso of Xylogics). 1682 1683- Sparc architectures, including the Sparcstation-1, are now 1684 supported thanks to Steve McCanne and Craig Leres. 1685 1686- SunOS 4 is now supported thanks to Micky Liu of Columbia 1687 University (micky@cunixc.cc.columbia.edu). 1688 1689- IP options are now printed. 1690 1691- RIP packets are now printed. 1692 1693- There's a -v flag that prints out more information than the 1694 default (e.g., it will enable printing of IP ttl, tos and id) 1695 and -q flag that prints out less (e.g., it will disable 1696 interpretation of AppleTalk-in-UDP). 1697 1698- The grammar has undergone substantial changes (if you have an 1699 earlier version of tcpdump, you should re-read the manual 1700 entry). 1701 1702 The most useful change is the addition of an expression 1703 syntax that lets you filter on arbitrary fields or values in the 1704 packet. E.g., "ip[0] > 0x45" would print only packets with IP 1705 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN 1706 packets. 1707 1708 The most painful change is that concatenation no longer means 1709 "and" -- e.g., you have to say "host foo and port bar" instead 1710 of "host foo port bar". The up side to this down is that 1711 repeated qualifiers can be omitted, making most filter 1712 expressions shorter. E.g., you can now say "ip host foo and 1713 (bar or baz)" to look at ip traffic between hosts foo and bar or 1714 between hosts foo and baz. [The old way of saying this was "ip 1715 host foo and (ip host bar or ip host baz)".] 1716 1717v2.0 Sun Jan 13 12:20:40 PST 1991 1718 1719- Initial public release. 1720
