Install the latest Packet Capture Library In orer to compile ngrep on any platform, the relevant packet capture (PCAP) client support library must be installed. On UNIX, this is called ``libpcap'' and can be installed either from source or from a distribution's particular package management system. Some distributions separate the library itself from its development headers (i.e. libpcap-devel), so make sure to install both if this is the case. On Windows, the client support library is called ``WinPcap Developer's Pack'' and should be unpacked inside the parent directory of the ngrep source tree. The latest versions (as of this writing) are located at: UNIX: http://tcpdump.org/release/libpcap-0.9.5.tar.gz Win32: http://www.winpcap.org/install/bin/wpdpack_3_1.zip 2. Unpack the ngrep source Once the client packet capture client support library is installed, unpack the ngrep source to a directory. On Windows, this must be under the same parent directory as the WinPcap Developer's Pack. 3. Compile the ngrep program On UNIX, type the following from the root of the ngrep source tree: % ./configure && make On Windows, open the ``ngrep.sln'' file located in the ``win32'' subdirectory of the ngrep source tree using Visual Studio.NET. From there you should be able to Build the solution in either Debug or Release mode. Once this is done, copy the resulting ``ngrep.exe'' (located in either the ``Debug'' or ``Release'' subdirectory depending on compile configuration) into any directory in your path for easy usage (``c:\windows'', for instance). Please ignore the warnings associated with the GNU Regex library included in the ngrep source tree. 4. Install the PCAP kernel driver ngrep is a PCAP-based program and therefore requires the PCAP kernel driver to be installed before it will function properly. The PCAP Driver is already integrated into the vast majority of UNIX and Linux kernels released within the last ~10 years. The Windows Platform, however, does not come with an integrated PCAP kernel driver by default, so it is necessary to install one before ngrep will work. The latest version (as of this writing) is located at: http://www.winpcap.org/install/bin/WinPcap_3_1.exe Getting Help ------------ On UNIX, if you still have problems compiling or are compiling on an unsupported OS, try playing with other build types -- i.e. if you have a BSD derived system, try the BSD build type. Please email me for help if you if you still have problems, however please try to help yourself first and search Google for possible answers before contacting me.

Description: ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop. Usage: ngrep <-IO pcap_dump> <-n num> <-d dev> <-A num> <-s snaplen> <-S limitlen> <-W normal|byline|single|none> <-c cols> <-P char> <-F file> -h is help/usage -V is version information -q is be quiet (don't print packet reception hash marks) -e is show empty packets -i is ignore case -v is invert match -R is don't do privilege revocation logic -x is print in alternate hexdump format -X is interpret match expression as hexadecimal -w is word-regex (expression must match as a word) -p is don't go into promiscuous mode -l is make stdout line buffered -D is replay pcap_dumps with their recorded time intervals -t is print timestamp every time a packet is matched -T is print delta timestamp every time a packet is matched -M is don't do multi-line match (do single-line match instead) -I is read packet stream from pcap format file pcap_dump -O is dump matched packets in pcap format to pcap_dump -n is look at only num packets -A is dump num packets after a match -s is set the bpf caplen -S is set the limitlen on matched packets -W is set the dump format (normal, byline, single, none) -c is force the column width to the specified size -P is set the non-printable display char to what is specified -F is read the bpf filter from the specified file -N is show sub protocol number On UNIX: -d is use specified device instead of the pcap default On Win32: -d is use specified device (index) instead of the pcap default -L is show the winpcap device list index Tips: o When the intention is to match all packets (i.e. blank regex), it is technically faster to use an empty regex (``'') than to use ``.*'' or ``*''. o When sniffing interfaces that are very busy or are seeing large amounts of packet traffic, make sure to craft a BPF filter to limit what PCAP has to deliver to ngrep. The ngrep parser takes a certain amount of time and while negligible on a slow interface, it can add up very quickly on a busy one. o Hexadecimal expressions can be in straight numeric form, 'DEADBEEF', or in symbolic form, '0xDEADBEEF'. A byte is the smallest unit of measure you can match against. o As of v1.28, ngrep doesn't require a match expression. However, there are cases where ngrep can be confused and think part of your bpf filter is the match expression, as in: % ngrep not port 80 interface: eth0 (192.168.1.0/255.255.255.0) filter: ip and ( port 80 ) match: not In cases like this, you will need to specify a blank match expression: % ngrep '' not port 80 interface: eth0 (192.168.1.0/255.255.255.0) filter: ip and ( not port 80 ) Please see http://ngrep.sourceforge.net/usage.html for more detailed examples describing ngrep usage. Miscellany: Please see the ``doc/CREDITS.txt'' file for a listing of the people who helped make ngrep what it is today. Also, please note that ngrep is released under a BSD-style license, though it currently relies upon the GNU regex library, which is protected under the GPL. Also, it is _highly recommended_ that you upgrade to the latest version of libpcap. All versions 0.5 and more recent fix really annoying and in some cases fatal problems with the packet capture library. If you happen to be using Windows, please check the WinPcap site to see if there are any updates.

The obvious conclusion is that GNU regex is the reigning king of speed, and that with regular expression engines optimization matters significantly. (Please note that I tried other third-party regex libraries like RxSpencer's and libhackerlab's, and none came close to comparing.) The test subject was "how now brown cow", and the pattern we were searching for in the match case was "now brown", and in the non-match case "not brown". Obviously, the speed of matches is directly related to the actual regex itself, and a well-formulated regex certainly performs more efficiently than a simple substring match. However, this test is reasonably indicative of how most people use ngrep, so the test results are still useful. Granted, on the single-match level the time difference is absolutely unnoticeable (it took 100 million loop iterations to compute something worthwhile), so this may not mean anything to you. Likewise, the stripped binary sizes are also within 10k of each other on the test compile box. If licensing terms are more sensitive for you than speed then compile against PCRE, which is available under the Artistic License (Free as in Beer). Otherwise, in all other cases the GNU regex library is the best candidate, and the speed can really help when piping those 500MB pcap dump files through ngrep over and over for analysis.

It currently recognizes TCP, UDP and ICMP across Ethernet, PPP, SLIP, FDDI and null interfaces, and understands bpf filter logic in the same fashion as more common packet sniffing tools, such as .BR tcpdump (8) and .BR snoop (1). .SH OPTIONS .IP -h Display help/usage information. .IP -N Show sub-protocol number along with single-character identifier (useful when observing raw or unknown protocols). .IP -X Treat the match expression as a hexadecimal string. See the explanation of \fImatch expression\fP below. .IP -V Display version information. .IP -i Ignore case for the regex expression. .IP -w Match the regex expression as a word. .IP -q Be quiet; don't output any information other than packet headers and their payloads (if relevant). .IP -p Don't put the interface into promiscuous mode. .IP -e Show empty packets. Normally empty packets are discarded because they have no payload to search. If specified, empty packets will be shown, regardless of the specified regex expression. .IP -v Invert the match; only display packets that don't match. .IP -x Dump packet contents as hexadecimal as well as ASCII. .IP -l Make stdout line buffered. .IP -D When reading pcap_dump files, replay them at their recorded time intervals (mimic realtime). .IP -t Print a timestamp in the form of YYYY/MM/DD HH:MM:SS.UUUUUU everytime a packet is matched. .IP -T Print a timestamp in the form of +S.UUUUUU, indicating the delta between packet matches. .IP -R Do not try to drop privileges to the DROPPRIVS_USER. ngrep makes no effort to validate input from live or offline sources as it is focused more on performance and handling large amounts of data than protocol correctness, which is most often a fair assumption to make. However, sometimes it matters and thus as a rule ngrep will try to be defensive and drop any root privileges it might have. There exist scenarios where this behaviour can become an obstacle, so this option is provided to end-users who want to disable this feature, but must do so with an understanding of the risks. Packets can be randomly malformed or even specifically designed to overflow sniffers and take control of them, and revoking root privileges is currently the only risk mitigation ngrep employs against such an attack. Use this option and turn it off at your own risk. .IP "-c cols" Explicitly set the console width to ``cols''. Note that this is the console width, and not the full width of what ngrep prints out as payloads; depending on the output mode ngrep may print less than ``cols'' bytes per line (indentation). .IP "-F file" Read in the bpf filter from the specified filename. This is a compatibility option for users familiar with tcpdump. Please note that specifying ``-F'' will override any bpf filter specified on the command-line. .IP "-P char" Specify an alternate character to signify non-printable characters when displayed. The default is ``.''. .IP "-W normal|byline|single|none" Specify an alternate manner for displaying packets, when not in hexadecimal mode. The ``byline'' mode honors embedded linefeeds, wrapping text only when a linefeed is encountered. The ``none'' mode doesn't wrap under any circumstance (entire payload is displayed on one line). The ``single'' mode is conceptually the same as ``none'', except that everything including IP and source/destination header information is all on one line. ``normal'' is the default mode and is only included for completeness. This option is incompatible with ``-x''. .IP "-s snaplen" Set the bpf caplen to snaplen (default 65536). .IP "-S limitlen" Set the upper limit on the size of packets that ngrep will look at. Useful for looking at only the first N bytes of packets without changing the BPF snaplen. .IP "-I pcap_dump" Input file pcap_dump into ngrep. Works with any pcap-compatible dump file format. This option is useful for searching for a wide range of different patterns over the same packet stream. .IP "-O pcap_dump" Output matched packets to a pcap-compatible dump file. This feature does not interfere with normal output to stdout. .IP "-n num" Match only .I \fInum\fP packets total, then exit. .IP "-d dev" By default ngrep will select a default interface to listen on. Use this option to force ngrep to listen on interface \fIdev\fP. .IP "-A num" Dump \fInum\fP packets of trailing context after matching a packet. .IP "-W normal|byline|none" Alter the method by which ngrep displays packet payload. ``normal'' mode represents the standard behaviour, ``byline'' instructs ngrep to respect embedded linefeeds (useful for observing HTTP transactions, for instance), and ``none'' results in the payload on one single line (useful for scripted processing of ngrep output). .IP "-c cols" Ignore the detected terminal width and force the column width to the specified size. .IP "-P char" Change the non-printable character from the default ``.'' to the character specified. .IP "\fI match expression\fP" A match expression is either an extended regular expression, or if the \fI-X\fP option is specified, a string signifying a hexadecimal value. An extended regular expression follows the rules as implemented by the .B GNU regex .BR library . Hexadecimal expressions can optionally be preceded by `0x'. E.g., `DEADBEEF', `0xDEADBEEF'. .IP "\fI bpf filter\fP" Selects a filter that specifies what packets will be dumped. If no \fIbpf filter\fP is given, all IP packets seen on the selected interface will be dumped. Otherwise, only packets for which \fIbpf filter\fP is `true' will be dumped. .LP The \fIbpf filter\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 blort', `net 1.2.3', `port 80'. 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 1.2.3', `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 are restricted to ip-only protocols. Possible protos are: .B tcp , .B udp and .BR icmp . e.g., `udp src foo' or `tcp port 21'. If there is no proto qualifier, all protocols consistent with the type are assumed. E.g., `src foo' means `ip and ((tcp or udp) src foo)', `net bar' means `ip and (net bar)', and `port 53' means `ip and ((tcp or udp) port 53)'. .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 blort 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 .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. I.e., the ethernet source or destination address was \fIhost\fP but neither the IP source nor the IP destination was \fIhost\fP. \fIHost\fP must be a name and must be found in both /etc/hosts and /etc/ethers. (An equivalent expression is .in +.5i .nf \fBether host \fIehost \fBand not host \fIhost\fR .fi .in -.5i which can be used with either names or numbers for \fIhost / ehost\fP.) .IP "\fBdst net \fInet\fR" True if the IP destination address of the packet has a network number of \fInet\fP. \fINet\fP may be either a name from /etc/networks or a network number (see \fInetworks(4)\fP for details). .IP "\fBsrc net \fInet\fR" True if the IP source address of the packet has a network number of \fInet\fP. .IP "\fBnet \fInet\fR" True if either the IP source or destination address of the packet has a network number of \fInet\fP. .IP "\fBnet \fInet\fR \fBmask \fImask\fR" True if the IP address matches \fInet\fR with the specific netmask. May be qualified with \fBsrc\fR or \fBdst\fR. .IP "\fBnet \fInet\fR/\fIlen\fR" True if the IP address matches \fInet\fR a netmask \fIlen\fR bits wide. May be qualified with \fBsrc\fR or \fBdst\fR. .IP "\fBdst port \fIport\fR" True if the packet is ip/tcp or ip/udp and has a destination port value of \fIport\fP. The \fIport\fP can be a number or a name used in /etc/services (see .IR tcp (4P) and .IR udp (4P)). If a name is used, both the port number and protocol are checked. 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 \fItcp\fP, \fIudp\fP or \fIicmp\fP. Note that the identifiers \fItcp\fP and \fIudp\fP are also keywords and must be escaped via backslash (\\), which is \\\\ in the C-shell. .IP "\fBip broadcast\fR" True if the packet is an IP broadcast packet. It checks for both the all-zeroes and all-ones broadcast conventions, and looks up the local subnet mask. .IP "\fBip multicast\fR" True if the packet is an IP multicast packet. .IP "\fBip\fR" Abbreviation for: .in +.5i .nf \fBether proto ip\fR .fi .IP "\fBtcp\fR, \fBudp\fR, \fBicmp\fR" Abbreviations for: .in +.5i .nf \fBip proto \fIp\fR .fi .in -.5i where \fIp\fR is one of the above protocols. .IP "\fIexpr relop expr\fR" True if the relation holds, where \fIrelop\fR is one of >, <, >=, <=, =, !=, and \fIexpr\fR is an arithmetic expression composed of integer constants (expressed in standard C syntax), the normal binary operators [+, -, *, /, &, |], a length operator, and special packet data accessors. To access data inside the packet, use the following syntax: .in +.5i .nf \fIproto\fB [ \fIexpr\fB : \fIsize\fB ]\fR .fi .in -.5i \fIProto\fR is one of \fBip, tcp, udp \fRor \fBicmp\fR, and indicates the protocol layer for the index operation. The byte offset, relative to the indicated protocol layer, is given by \fIexpr\fR. \fISize\fR is optional and indicates the number of bytes in the field of interest; it can be either one, two, or four, and defaults to one. The length operator, indicated by the keyword \fBlen\fP, gives the length of the packet. For example, `\fBether[0] & 1 != 0\fP' catches all multicast traffic. The expression `\fBip[0] & 0xf != 5\fP' catches all IP packets with options. The expression `\fBip[6:2] & 0x1fff = 0\fP' catches only unfragmented datagrams and frag zero of fragmented datagrams. This check is implicitly applied to the \fBtcp\fP and \fBudp\fP index operations. For instance, \fBtcp[0]\fP always means the first byte of the TCP \fIheader\fP, and never means the first byte of an intervening fragment. .LP Primitives may be combined using: .IP A parenthesized group of primitives and operators (parentheses are special to the Shell and must be escaped). .IP Negation (`\fB!\fP' or `\fBnot\fP'). .IP Concatenation (`\fB&&\fP' or `\fBand\fP'). .IP Alternation (`\fB||\fP' or `\fBor\fP'). .LP Negation has highest precedence. Alternation and concatenation have equal precedence and associate left to right. Note that explicit \fBand\fR tokens, not juxtaposition, are now required for concatenation. .LP If an identifier is given without a keyword, the most recent keyword is assumed. For example, .in +.5i .nf \fBnot host vs and ace\fR .fi .in -.5i is short for .in +.5i .nf \fBnot host vs and host ace\fR .fi .in -.5i which should not be confused with .in +.5i .nf \fBnot ( host vs or ace )\fR .fi .in -.5i .LP Expression arguments can be passed to ngrep as either a single argument or as multiple arguments, whichever is more convenient. Generally, if the expression contains Shell metacharacters, it is easier to pass it as a single, quoted argument. Multiple arguments are concatenated with spaces before being parsed. .SH DIAGNOSTICS Errors from .B ngrep, libpcap, and the .B GNU regex library are all output to stderr. .SH AUTHOR Written by Jordan Ritter . .SH REPORTING BUGS Please report bugs to the ngrep's Sourceforge Bug Tracker, located at http://sourceforge.net/projects/ngrep/ Non-bug, non-feature-request general feedback should be sent to the author directly by email. .SH NOTES ALL YOUR BASE ARE BELONG TO US. ngrep-1.45.ds2/ngrep.c000066400000000000000000001063011065765065000145370ustar00rootroot00000000000000/* * $Id: ngrep.c,v 1.93 2006/11/28 13:38:43 jpr5 Exp $ * * Copyright (c) 2006 Jordan Ritter * * Please refer to the LICENSE file for more information. * */ #if defined(BSD) || defined(SOLARIS) || defined(MACOSX) #include #include #include #include #include #include #include #include #include #include #endif #if defined(OSF1) #include #include #include #include #include #include #include #include #include #endif #if defined(LINUX) #include #include #include #include #include #include #include #endif #if defined(AIX) #include #include #include #include #include #include #endif #if defined(_WIN32) #include #include #include #include #include #include #define strcasecmp stricmp #else #include #include #include #include #include #endif #include #include #include #if !defined(_WIN32) #include #include #endif #include #ifdef HAVE_CONFIG_H #include "config.h" #endif #if USE_IPv6 && !defined(_WIN32) #include #include #endif #if USE_PCRE #include "pcre-5.0/pcre.h" #else #include "regex-0.12/regex.h" #endif #include "ngrep.h" static char rcsver[] = "$Revision: 1.93 $"; /* * Configuration Options */ uint16_t snaplen = 65535, limitlen = 65535, promisc = 1, to = 100; uint16_t match_after = 0, keep_matching = 0, matches = 0, max_matches = 0; uint8_t re_match_word = 0, re_ignore_case = 0, re_multiline_match = 1; uint8_t show_empty = 0, show_hex = 0, show_proto = 0, quiet = 0; uint8_t invert_match = 0, bin_match = 0; uint8_t live_read = 1, want_delay = 0; uint8_t dont_dropprivs = 0; char *read_file = NULL, *dump_file = NULL; char *usedev = NULL; char nonprint_char = '.'; /* * GNU Regex/PCRE */ #if USE_PCRE int32_t err_offset; char *re_err = NULL; pcre *pattern = NULL; pcre_extra *pattern_extra = NULL; #else const char *re_err = NULL; struct re_pattern_buffer pattern; #endif /* * Matching */ char *match_data = NULL, *bin_data = NULL; uint16_t match_len = 0; int8_t (*match_func)() = &blank_match_func; int8_t dump_single = 0; void (*dump_func)(unsigned char *, uint32_t) = &dump_formatted; /* * BPF/Network */ char *filter = NULL, *filter_file = NULL; char pc_err[PCAP_ERRBUF_SIZE]; uint8_t link_offset; uint8_t radiotap_present = 0; pcap_t *pd = NULL; pcap_dumper_t *pd_dump = NULL; struct bpf_program pcapfilter; struct in_addr net, mask; /* * Timestamp/delay functionality */ struct timeval prev_ts = {0, 0}, prev_delay_ts = {0,0}; #if defined(_WIN32) struct timeval delay_tv; FD_SET delay_fds; SOCKET delay_socket = 0; #endif void (*print_time)() = NULL, (*dump_delay)() = dump_delay_proc_init; /* * When !Win32, windowsize stuff.
