 |   formats. | 
 |  |

 |   Thanks to Danny J. Mitzel (mitzel@ipsilon.com) | 
 |  | 
 | - Rewrite ospf printer to improve truncation checks. |

 | - Don't parse tcp options past the EOL. As noted by David Sacerdote | 
 |   (davids@secnet.com). Also, check tcp options to make sure they ar | 
 |   actually in the tcp header (in addition to the normal truncation | 
 |   checks). Fix the SACK code to print the N blocks (instead of the | 
 |   first block N times). | 
 |  | 
 | - Don't say really small UDP packets are truncated just because they | 
 |   aren't big enough to be a RPC. As noted by David Sacerdote. |

 |  | 
 | v3.0.2 Thu Apr 20 21:28:16 PDT 1995 | 
 |  | 
 | - Change configuration to not use gcc v2 flags with gcc v1. | 
 |  | 
 | - Redo gmt2local() so that it works under BSDI (which seems to return | 
 |   an empty timezone struct from gettimeofday()). Based on report from | 
 |   Terry Kennedy (terry@spcvxa.spc.edu). | 
 |  | 
 | - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based | 
 |   on report from Mark Andrews (mandrews@alias.com). | 
 |  | 
 | - Don't pass cc flags to gcc. Resulted from a bug report from Rainer |

 |  | 
 | - Added support for printing tcp option timestamps thanks to | 
 |   Mark Andrews (mandrews@alias.com). | 
 |  | 
 | - Reorganize protocol dumpers to take const pointers to packets so they | 
 |   never change the contents (i.e., they used to do endian conversions | 
 |   in place).  Previously, whenever more than one pass was taken over | 
 |   the packet, the packet contents would be dumped incorrectly (i.e., | 
 |   the output form -x would be wrong on little endian machines because | 
 |   the protocol dumpers would modify the data).  Thanks to Charles Hannum | 
 |   (mycroft@gnu.ai.mit.edu) for reporting this problem. | 
 |  | 
 | - Added support for decnet protocol dumping thanks to Jeff Mogul | 
 |   (mogul@pa.dec.com). | 
 |  |

 |   (brad@fcr.com). | 
 |  | 
 | - Added check to verify IP header checksum under -v thanks to | 
 |   Brad Parker (brad@fcr.com). |

 |  | 
 | - print-arp.c: Print hardware ethernet addresses if they're not | 
 |   what we expect. | 
 |  | 
 | - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. | 
 |   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). | 
 |  | 
 | - print-fddi.c: Improvements. Thanks to Jeffrey Mogul | 
 |   (mogul@pa.dec.com). |

 |   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. | 
 |  | 
 | - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. | 
 |   By default, only the inner packet is dumped, appended with the token | 
 |   "(encap)".  Under -v, both the inner and output packets are dumped | 
 |   (on the same line).  Note that the filter applies to the original packet, | 
 |   not the encapsulated packet.  So if you run tcpdump on a net with an | 
 |   IP Multicast tunnel, you cannot filter out the datagrams using the | 
 |   conventional syntax.  (You can filter away all the ip-in-ip traffic | 
 |   with "not ip proto 4".) | 
 |  | 
 | - print-nfs.c: Keep pending rpc's in circular table. Add generic | 
 |   nfs header and remove os dependences. Thanks to Jeffrey Mogul. | 
 |  | 
 | - print-ospf.c: Improvements. Thanks to Jeffrey Mogul. | 
 |  | 
 | - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" | 
 |   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords | 
 |   Add && and || operators | 
 |  | 
 | v2.2.1 Tue Jun 6 17:57:22 PDT 1992 | 
 |  | 
 | - Fix bug with -c flag. | 
 |  | 
 | v2.2 Fri May 22 17:19:41 PDT 1992 | 
 |  | 
 | - savefile.c: Remove hack that shouldn't have been exported. Add | 
 |   truncate checks. | 
 |  | 
 | - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0' | 
 |   matches non-echo/reply ICMP packets. | 
 |  | 
 | - Many improvements to filter code optimizer. | 
 |  | 
 | - Added 'multicast' keyword and extended the 'broadcast' keyword can now be | 
 |   so that protocol qualifications are allowed. For example, "ip broadcast" | 
 |   and "ether multicast" are valid filters. | 
 |  | 
 | - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). | 
 |   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel | 
 |   patches to netinet/if_loop.c. | 
 |  | 
 | - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. | 
 |   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. | 
 |  | 
 | - Added EGP and OSPF printers, thanks to Jeffrey Honig. | 
 |  | 
 | v2.1 Tue Jan 28 11:00:14 PST 1992 | 
 |  | 
 | - Internal release (never publically exported). | 
 |  | 
 | v2.0.1 Sun Jan 26 21:10:10 PDT | 
 |  | 
 | - Various byte ordering fixes. | 
 |  | 
 | - Add truncation checks. | 
 |  | 
 | - inet.c: Support BSD style SIOCGIFCONF. | 
 |  | 
 | - nametoaddr.c: Handle multi addresses for single host. | 
 |  | 
 | - optimize.c: Rewritten. | 
 |  | 
 | - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous | 
 |   for broadcast nets. | 
 |  | 
 | - print-atal.c: Fix an alignment bug (thanks to | 
 |   stanonik@nprdc.navy.mil) Add missing printf() argument. | 
 |  | 
 | - print-bootp.c: First attempt at decoding the vendor buffer. | 
 |  | 
 | - print-domain.c: Fix truncation checks. | 
 |  | 
 | - print-icmp.c: Calculate length of packets from the ip header. | 
 |  | 
 | - print-ip.c: Print frag id in decimal (so it's easier to match up | 
 |   with non-frags). Add support for ospf, egp and igmp. | 
 |  | 
 | - print-nfs.c: Lots of changes. | 
 |  | 
 | - print-ntp.c: Make some verbose output depend on -v. | 
 |  | 
 | - print-snmp.c: New version from John LoVerso. | 
 |  | 
 | - print-tcp.c: Print rfc1072 tcp options. | 
 |  | 
 | - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits | 
 |   (microseconds) worth of precision. Fix uid bugs. | 
 |  | 
 | - A packet dumper has been added (thanks to Jeff Mogul of DECWRL). | 
 |   With this option, you can create an architecture independent binary | 
 |   trace file in real time, without the overhead of the packet printer. | 
 |   At a later time, the packets can be filtered (again) and printed. | 
 |  | 
 | - BSD is supported.  You must have BPF in your kernel. | 
 |   Since the filtering is now done in the kernel, fewer packets are | 
 |   dropped.  In fact, with BPF and the packet dumper option, a measly | 
 |   Sun 3/50 can keep up with a busy network. | 
 |  | 
 | - Compressed SLIP packets can now be dumped, provided you use our | 
 |   SLIP software and BPF.  These packets are dumped as any other IP | 
 |   packet; the compressed headers are dumped with the '-e' option. | 
 |  | 
 | - Machines with little-endian byte ordering are supported (thanks to | 
 |   Jeff Mogul). | 
 |  | 
 | - Ultrix 4.0 is supported (also thanks to Jeff Mogul). | 
 |  | 
 | - IBM RT and Stanford Enetfilter support has been added by | 
 |   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under | 
 |   both the vanilla Enetfilter interface, and the extended interface | 
 |   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. | 
 |  | 
 | - TFTP packets are now printed (requests only). | 
 |  | 
 | - BOOTP packets are now printed. | 
 |  | 
 | - SNMP packets are now printed. (thanks to John LoVerso of Xylogics). | 
 |  | 
 | - Sparc architectures, including the Sparcstation-1, are now | 
 |   supported thanks to Steve McCanne and Craig Leres. | 
 |  | 
 | - SunOS 4 is now supported thanks to Micky Liu of Columbia | 
 |   University (micky@cunixc.cc.columbia.edu). | 
 |  | 
 | - IP options are now printed. | 
 |  | 
 | - RIP packets are now printed. | 
 |  | 
 | - There's a -v flag that prints out more information than the | 
 |   default (e.g., it will enable printing of IP ttl, tos and id) | 
 |   and -q flag that prints out less (e.g., it will disable | 
 |   interpretation of AppleTalk-in-UDP). | 
 |  | 
 | - The grammar has undergone substantial changes (if you have an | 
 |   earlier version of tcpdump, you should re-read the manual | 
 |   entry). | 
 |  | 
 |   The most useful change is the addition of an expression | 
 |   syntax that lets you filter on arbitrary fields or values in the | 
 |   packet.  E.g., "ip[0] > 0x45" would print only packets with IP | 
 |   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN | 
 |   packets. | 
 |  | 
 |   The most painful change is that concatenation no longer means | 
 |   "and" -- e.g., you have to say "host foo and port bar" instead | 
 |   of "host foo port bar".  The up side to this down is that | 
 |   repeated qualifiers can be omitted, making most filter | 
 |   expressions shorter.  E.g., you can now say "ip host foo and | 
 |   (bar or baz)" to look at ip traffic between hosts foo and bar or | 
 |   between hosts foo and baz.  [The old way of saying this was "ip | 
 |   host foo and (ip host bar or ip host baz)".] |
