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). + +- Fix bug that caused length of packet to be incorrectly printed + (off by ether header size) for unknown ethernet types thanks + to Greg Miller (gmiller@kayak.mitre.org). + +- Added support for IPX protocol dumping thanks to Brad Parker + (brad@fcr.com). + +- Added check to verify IP header checksum under -v thanks to + Brad Parker (brad@fcr.com). + +- Move packet capture code to new libpcap library (which is + packaged separately). + +- Prototype everything and assume an ansi compiler. + +- 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). + +- print-icmp.c: Byte swap netmask before printing. Thanks to + 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)".] + +v2.0 Sun Jan 13 12:20:40 PST 1991 + +- Initial public release. diff --git a/contrib/tcpdump/FILES b/contrib/tcpdump/FILES new file mode 100644 index 0000000..5d4c338 --- /dev/null +++ b/contrib/tcpdump/FILES @@ -0,0 +1,80 @@ +CHANGES +FILES +INSTALL +Makefile.in +README +VERSION +aclocal.m4 +addrtoname.c +addrtoname.h +appletalk.h +atime.awk +bootp.h +bpf_dump.c +config.guess +config.sub +configure +configure.in +decnet.h +ethertype.h +extract.h +fddi.h +igrp.h +install-sh +interface.h +ipx.h +lbl/gnuc.h +lbl/os-solaris2.h +lbl/os-sunos4.h +llc.h +machdep.c +machdep.h +makemib +mib.h +mkdep +netbios.h +nfsfh.h +nfsv2.h +ntp.h +ospf.h +packetdat.awk +parsenfsfh.c +print-arp.c +print-atalk.c +print-atm.c +print-bootp.c +print-decnet.c +print-domain.c +print-dvmrp.c +print-egp.c +print-ether.c +print-fddi.c +print-icmp.c +print-igrp.c +print-ip.c +print-ipx.c +print-isoclns.c +print-krb.c +print-llc.c +print-netbios.c +print-nfs.c +print-ntp.c +print-null.c +print-ospf.c +print-pim.c +print-ppp.c +print-rip.c +print-sl.c +print-snmp.c +print-sunrpc.c +print-tcp.c +print-tftp.c +print-udp.c +print-wb.c +send-ack.awk +stime.awk +strcasecmp.c +tcpdump.1 +tcpdump.c +util.c +vfprintf.c diff --git a/contrib/tcpdump/INSTALL b/contrib/tcpdump/INSTALL new file mode 100644 index 0000000..c5512c0 --- /dev/null +++ b/contrib/tcpdump/INSTALL @@ -0,0 +1,116 @@ +@(#) $Header: INSTALL,v 1.25 96/07/21 04:02:01 leres Exp $ (LBL) + +If you have not built libpcap, do so first.

The original distribution is +available via anonymous ftp to ftp.ee.lbl.gov, in tcpdump.tar.Z. + +Tcpdump now uses libcap, a system-independent interface for user-level +packet capture. Before building tcpdump, you must first retrieve and +build libpcap, also from LBL, in: + + ftp://ftp.ee.lbl.gov/libpcap.tar.Z + +Once libpcap is built (either install it or make sure it's in +../libpcap), you can build tcpdump using the procedure in the INSTALL +file. + +The program is loosely based on SMI's "etherfind" although none +of the etherfind code remains. It was originally written by Van +Jacobson as part of an ongoing research project to investigate and +improve tcp and internet gateway performance. The parts of the +program originally taken from Sun's etherfind were later re-written +by Steven McCanne of LBL. To insure that there would be no vestige +of proprietary code in tcpdump, Steve wrote these pieces from the +specification given by the manual entry, with no access to the +source of tcpdump or etherfind. + +Over the past few years, tcpdump has been steadily improved +by the excellent contributions from the Internet community +(just browse through the CHANGES file). We are grateful for +all the input. + +Richard Stevens gives an excellent treatment of the Internet +protocols in his book ``TCP/IP Illustrated, Volume 1''. +If you want to learn more about tcpdump and how to interpret +its output, pick up this book. + +Some tools for viewing and analyzing tcpdump trace files are available +from the Internet Traffic Archive: + + http://town.hall.org/Archives/pub/ITA/ + +Problems, bugs, questions, desirable enhancements, source code +contributions, etc., should be sent to the email address +"tcpdump@ee.lbl.gov". + + - Steve McCanne + Craig Leres + Van Jacobson +------------------------------------- +This directory also contains some short awk programs intended as +examples of ways to reduce tcpdump data when you're tracking +particular network problems: + +send-ack.awk + Simplifies the tcpdump trace for an ftp (or other unidirectional + tcp transfer). Since we assume that one host only sends and + the other only acks, all address information is left off and + we just note if the packet is a "send" or an "ack". + + There is one output line per line of the original trace. + Field 1 is the packet time in decimal seconds, relative + to the start of the conversation. Field 2 is delta-time + from last packet. Field 3 is packet type/direction. + "Send" means data going from sender to receiver, "ack" + means an ack going from the receiver to the sender. A + preceding "*" indicates that the data is a retransmission. + A preceding "-" indicates a hole in the sequence space + (i.e., missing packet(s)), a "#" means an odd-size (not max + seg size) packet. Field 4 has the packet flags + (same format as raw trace). Field 5 is the sequence + number (start seq. num for sender, next expected seq number + for acks). The number in parens following an ack is + the delta-time from the first send of the packet to the + ack. A number in parens following a send is the + delta-time from the first send of the packet to the + current send (on duplicate packets only). Duplicate + sends or acks have a number in square brackets showing + the number of duplicates so far. + + Here is a short sample from near the start of an ftp: + 3.00 0.20 send . 512 + 3.20 0.20 ack . 1024 (0.20) + 3.20 0.00 send P 1024 + 3.40 0.20 ack . 1536 (0.20) + 3.80 0.40 * send . 0 (3.80) [2] + 3.82 0.02 * ack . 1536 (0.62) [2] + Three seconds into the conversation, bytes 512 through 1023 + were sent. 200ms later they were acked. Shortly thereafter + bytes 1024-1535 were sent and again acked after 200ms. + Then, for no apparent reason, 0-511 is retransmitted, 3.8 + seconds after its initial send (the round trip time for this + ftp was 1sec, +-500ms). Since the receiver is expecting + 1536, 1536 is re-acked when 0 arrives. + +packetdat.awk + Computes chunk summary data for an ftp (or similar + unidirectional tcp transfer). [A "chunk" refers to + a chunk of the sequence space -- essentially the packet + sequence number divided by the max segment size.] + + A summary line is printed showing the number of chunks, + the number of packets it took to send that many chunks + (if there are no lost or duplicated packets, the number + of packets should equal the number of chunks) and the + number of acks. + + Following the summary line is one line of information + per chunk. The line contains eight fields: + 1 - the chunk number + 2 - the start sequence number for this chunk + 3 - time of first send + 4 - time of last send + 5 - time of first ack + 6 - time of last ack + 7 - number of times chunk was sent + 8 - number of times chunk was acked + (all times are in decimal seconds, relative to the start + of the conversation.) + + As an example, here is the first part of the output for + an ftp trace: + + # 134 chunks. 536 packets sent. 508 acks. + 1 1 0.00 5.80 0.20 0.20 4 1 + 2 513 0.28 6.20 0.40 0.40 4 1 + 3 1025 1.16 6.32 1.20 1.20 4 1 + 4 1561 1.86 15.00 2.00 2.00 6 1 + 5 2049 2.16 15.44 2.20 2.20 5 1 + 6 2585 2.64 16.44 2.80 2.80 5 1 + 7 3073 3.00 16.66 3.20 3.20 4 1 + 8 3609 3.20 17.24 3.40 5.82 4 11 + 9 4097 6.02 6.58 6.20 6.80 2 5 + + This says that 134 chunks were transferred (about 70K + since the average packet size was 512 bytes). It took + 536 packets to transfer the data (i.e., on the average + each chunk was transmitted four times). Looking at, + say, chunk 4, we see it represents the 512 bytes of + sequence space from 1561 to 2048. It was first sent + 1.86 seconds into the conversation. It was last + sent 15 seconds into the conversation and was sent + a total of 6 times (i.e., it was retransmitted every + 2 seconds on the average). It was acked once, 140ms + after it first arrived. + +stime.awk +atime.awk + Output one line per send or ack, respectively, in the form + <time> <seq. number> + where <time> is the time in seconds since the start of the + transfer and <seq. number> is the sequence number being sent + or acked. I typically plot this data looking for suspicious + patterns. + + +The problem I was looking at was the bulk-data-transfer +throughput of medium delay network paths (1-6 sec. round trip +time) under typical DARPA Internet conditions. The trace of the +ftp transfer of a large file was used as the raw data source. +The method was: + + - On a local host (but not the Sun running tcpdump), connect to + the remote ftp. + + - On the monitor Sun, start the trace going. E.g., + tcpdump host local-host and remote-host and port ftp-data >tracefile + + - On local, do either a get or put of a large file (~500KB), + preferably to the null device (to minimize effects like + closing the receive window while waiting for a disk write). + + - When transfer is finished, stop tcpdump. Use awk to make up + two files of summary data (maxsize is the maximum packet size, + tracedata is the file of tcpdump tracedata): + awk -f send-ack.awk packetsize=avgsize tracedata >sa + awk -f packetdat.awk packetsize=avgsize tracedata >pd + + - While the summary data files are printing, take a look at + how the transfer behaved: + awk -f stime.awk tracedata | xgraph + (90% of what you learn seems to happen in this step). + + - Do all of the above steps several times, both directions, + at different times of day, with different protocol + implementations on the other end. + + - Using one of the Unix data analysis packages (in my case, + S and Gary Perlman's Unix|Stat), spend a few months staring + at the data. + + - Change something in the local protocol implementation and + redo the steps above. + + - Once a week, tell your funding agent that you're discovering + wonderful things and you'll write up that research report + "real soon now". + diff --git a/contrib/tcpdump/VERSION b/contrib/tcpdump/VERSION new file mode 100644 index 0000000..e4604e3 --- /dev/null +++ b/contrib/tcpdump/VERSION @@ -0,0 +1 @@ +3.2.1 diff --git a/contrib/tcpdump/aclocal.m4 b/contrib/tcpdump/aclocal.m4 new file mode 100644 index 0000000..2c017f6 --- /dev/null +++ b/contrib/tcpdump/aclocal.m4 @@ -0,0 +1,505 @@ +dnl @(#) $Header: aclocal.m4,v 1.32 96/07/23 22:55:48 leres Exp $ (LBL) +dnl +dnl Copyright (c) 1995, 1996 +dnl The Regents of the University of California.

E.g., +.br +``tcpdump\ \ \-l\ \ |\ \ tee dat'' or +``tcpdump\ \ \-l \ \ > dat\ \ &\ \ tail\ \ \-f\ \ dat''. +.TP +.B \-n +Don't convert addresses (i.e., host addresses, port numbers, etc.) to names. +.TP +.B \-N +Don't print domain name qualification of host names. E.g., +if you give this flag then \fItcpdump\fP will print ``nic'' +instead of ``nic.ddn.mil''. +.TP +.B \-O +Do not run the packet-matching code optimizer. This is useful only +if you suspect a bug in the optimizer. +.TP +.B \-p +\fIDon't\fP put the interface +into promiscuous mode. Note that the interface might be in promiscuous +mode for some other reason; hence, `-p' cannot be used as an abbreviation for +`ether host {local-hw-addr} or ether broadcast'. +.TP +.B \-q +Quick (quiet?) output. Print less protocol information so output +lines are shorter. +.TP +.B \-r +Read packets from \fIfile\fR (which was created with the -w option). +Standard input is used if \fIfile\fR is ``-''. +.TP +.B \-s +Snarf \fIsnaplen\fP bytes of data from each packet rather than the +default of 68 (with SunOS's NIT, the minimum is actually 96). +68 bytes is adequate for IP, ICMP, TCP +and UDP but may truncate protocol information from name server and NFS +packets (see below). Packets truncated because of a limited snapshot +are indicated in the output with ``[|\fIproto\fP]'', where \fIproto\fP +is the name of the protocol level at which the truncation has occurred. +Note that taking larger snapshots both increases +the amount of time it takes to process packets and, effectively, +decreases the amount of packet buffering. This may cause packets to be +lost. You should limit \fIsnaplen\fP to the smallest number that will +capture the protocol information you're interested in. +.TP +.B \-T +Force packets selected by "\fIexpression\fP" to be interpreted the +specified \fItype\fR. Currently known types are +\fBrpc\fR (Remote Procedure Call), +\fBrtp\fR (Real-Time Applications protocol), +\fBrtcp\fR (Real-Time Applications control protocol), +\fBvat\fR (Visual Audio Tool), +and +\fBwb\fR (distributed White Board). +.TP +.B \-S +Print absolute, rather than relative, TCP sequence numbers. +.TP +.B \-t +\fIDon't\fP print a timestamp on each dump line. +.TP +.B \-tt +Print an unformatted timestamp on each dump line. +.TP +.B \-v +(Slightly more) verbose output. For example, the time to live +and type of service information in an IP packet is printed. +.TP +.B \-vv +Even more verbose output. For example, additional fields are +printed from NFS reply packets. +.TP +.B \-w +Write the raw packets to \fIfile\fR rather than parsing and printing +them out. They can later be printed with the \-r option. +Standard output is used if \fIfile\fR is ``-''. +.TP +.B \-x +Print each packet (minus its link level header) in hex. +The smaller of the entire packet or +.I snaplen +bytes will be printed. +.IP "\fI expression\fP" +.RS +selects which packets will be dumped. If no \fIexpression\fP +is given, all packets on the net will be dumped. Otherwise, +only packets for which \fIexpression\fP is `true' will be dumped. +.LP +The \fIexpression\fP consists of one or more +.I primitives. +Primitives usually consist of an +.I id +(name or number) preceded by one or more qualifiers. There are three +different kinds of qualifier: +.IP \fItype\fP +qualifiers say what kind of thing the id name or number refers to. +Possible types are +.BR host , +.B net +and +.BR port . +E.g., `host foo', `net 128.3', `port 20'. If there is no type +qualifier, +.B host +is assumed. +.IP \fIdir\fP +qualifiers specify a particular transfer direction to and/or from +.I id. +Possible directions are +.BR src , +.BR dst , +.B "src or dst" +and +.B "src and" +.BR dst . +E.g., `src foo', `dst net 128.3', `src or dst port ftp-data'. If +there is no dir qualifier, +.B "src or dst" +is assumed. +For `null' link layers (i.e. point to point protocols such as slip) the +.B inbound +and +.B outbound +qualifiers can be used to specify a desired direction. +.IP \fIproto\fP +qualifiers restrict the match to a particular protocol. Possible +protos are: +.BR ether , +.BR fddi , +.BR ip , +.BR arp , +.BR rarp , +.BR decnet , +.BR lat , +.BR sca , +.BR moprc , +.BR mopdl , +.B tcp +and +.BR udp . +E.g., `ether src foo', `arp net 128.3', `tcp port 21'. If there is +no proto qualifier, all protocols consistent with the type are +assumed. E.g., `src foo' means `(ip or arp or rarp) src foo' +(except the latter is not legal syntax), `net bar' means `(ip or +arp or rarp) net bar' and `port 53' means `(tcp or udp) port 53'. +.LP +[`fddi' is actually an alias for `ether'; the parser treats them +identically as meaning ``the data link level used on the specified +network interface.'' FDDI headers contain Ethernet-like source +and destination addresses, and often contain Ethernet-like packet +types, so you can filter on these FDDI fields just as with the +analogous Ethernet fields. FDDI headers also contain other fields, +but you cannot name them explicitly in a filter expression.] +.LP +In addition to the above, there are some special `primitive' keywords +that don't follow the pattern: +.BR gateway , +.BR broadcast , +.BR less , +.B greater +and arithmetic expressions. All of these are described below. +.LP +More complex filter expressions are built up by using the words +.BR and , +.B or +and +.B not +to combine primitives. E.g., `host foo and not port ftp and not port ftp-data'. +To save typing, identical qualifier lists can be omitted. E.g., +`tcp dst port ftp or ftp-data or domain' is exactly the same as +`tcp dst port ftp or tcp dst port ftp-data or tcp dst port domain'. +.LP +Allowable primitives are: +.IP "\fBdst host \fIhost\fR" +True if the IP destination field of the packet is \fIhost\fP, +which may be either an address or a name. +.IP "\fBsrc host \fIhost\fR" +True if the IP source field of the packet is \fIhost\fP. +.IP "\fBhost \fIhost\fP +True if either the IP source or destination of the packet is \fIhost\fP. +Any of the above host expressions can be prepended with the keywords, +\fBip\fP, \fBarp\fP, or \fBrarp\fP as in: +.in +.5i +.nf +\fBip host \fIhost\fR +.fi +.in -.5i +which is equivalent to: +.in +.5i +.nf +\fBether proto \fI\\ip\fB and host \fIhost\fR +.fi +.in -.5i +If \fIhost\fR is a name with multiple IP addresses, each address will +be checked for a match. +.IP "\fBether dst \fIehost\fP +True if the ethernet destination address is \fIehost\fP. \fIEhost\fP +may be either a name from /etc/ethers or a number (see +.IR ethers (3N) +for numeric format). +.IP "\fBether src \fIehost\fP +True if the ethernet source address is \fIehost\fP. +.IP "\fBether host \fIehost\fP +True if either the ethernet source or destination address is \fIehost\fP. +.IP "\fBgateway\fP \fIhost\fP +True if the packet used \fIhost\fP as a gateway.

If a number or ambiguous name is used, +only the port number is checked (e.g., \fBdst port 513\fR will print both +tcp/login traffic and udp/who traffic, and \fBport domain\fR will print +both tcp/domain and udp/domain traffic). +.IP "\fBsrc port \fIport\fR" +True if the packet has a source port value of \fIport\fP. +.IP "\fBport \fIport\fR" +True if either the source or destination port of the packet is \fIport\fP. +Any of the above port expressions can be prepended with the keywords, +\fBtcp\fP or \fBudp\fP, as in: +.in +.5i +.nf +\fBtcp src port \fIport\fR +.fi +.in -.5i +which matches only tcp packets whose source port is \fIport\fP. +.IP "\fBless \fIlength\fR" +True if the packet has a length less than or equal to \fIlength\fP. +This is equivalent to: +.in +.5i +.nf +\fBlen <= \fIlength\fP. +.fi +.in -.5i +.IP "\fBgreater \fIlength\fR" +True if the packet has a length greater than or equal to \fIlength\fP. +This is equivalent to: +.in +.5i +.nf +\fBlen >= \fIlength\fP. +.fi +.in -.5i +.IP "\fBip proto \fIprotocol\fR" +True if the packet is an ip packet (see +.IR ip (4P)) +of protocol type \fIprotocol\fP. +\fIProtocol\fP can be a number or one of the names +\fIicmp\fP, \fIigrp\fP, \fIudp\fP, \fInd\fP, or \fItcp\fP. +Note that the identifiers \fItcp\fP, \fIudp\fP, and \fIicmp\fP are also +keywords and must be escaped via backslash (\\), which is \\\\ in the C-shell. +.IP "\fBether broadcast\fR" +True if the packet is an ethernet broadcast packet.
