ChangeLog less more
0 2005-08-22 v1.4
1 - nfreplay: Bug fix sending flows.
2 - nfdump: Add CryptoPAn code to anonymize IP addresses. New option -K
3 - nfdump: Change time format in output to ISO 8601 compatible: e.g. 1981-04-05 14:30:30.100
4 - nfdump: Add scaling factor k,m,g to number in filter syntax: e.g. bytes > 1m
5 - nfdump: Create new output format extended with additional fields pps, bps and bpp
6 - nfdump: Rename output format extended to raw
7 - nfdump: More than one single flow element statistic ( -s ) is now possible

INSTALL less more
0 Installation:
1 -------------
2 The tools should work on any *nix flavor. They have been compiled
3 and tested on Linux, Solaris (32/64bit), OpenBSD (32/64bit) as well
4 as MacOSX.
5
6 ./configure
7 make
8 make install
9
10 should do the job.
11
12 configure options:
13 --enable-64
14 When using Snore CC on Solaris, you may compile 64 bit code.
15 default is NO
16
17 --enable-ftconv
18 Build ft2nfdump converter. The flow-tools sources are required
19 to build ft2nfdump.
20
21 --with-ftpath[=flow-tools sources]
22 When building ft2nfdump, configure expects to find the
23 flow-tools sources in ../flow-tools-0.67. In case of another
24 path, the flow-tools directory is specified.
25
26 The parser code produced by yacc or bison can generate some
27 warnings, when being compiled. These can safely be ignored.
28
29 On any Solaris, make sure you have flex installed, as lex
30 on Solaris does not compile the scanner properly.
31
32 Uninstalling:
33
34 make uninstall
35
36 Notes on compatibility:
37 nfdump 1.4 introduces milisecond resolution. This resulted in a small
38 change of the binary format of nfdump files. However, this change is
39 fully transparent to the user, which means, nfdump 1.4 is able to read
40 and process older files, and nfdump < 1.4 is able to read and process
41 nfdump 1,4 files. But note: The milisecond resolution is only available
42 in data files captured with nfcapd v1.4 and processed with nfdump 1.4.

0 This is a small description, what the nfdump tools do and how they work.
1 Nfdump is distributed under the BSD license - see BSD-license.txt
2
3 The nfdump tools collect and process netflow data on the command line.
4 They are part of the NFSEN project which is explained more detailed at
5 http://www.terena.nl/tech/task-forces/tf-csirt/meeting12/nfsen-Haag.pdf
6
7 The Web interface mentioned is not part of nfdump and will be released
8 separately.
9
10 nfdump tools overview:
11 ----------------------
12
13 nfcapd - netflow capture daemon.
14 Reads the netflow data from the network and stores the data into files.
15 Automatically rotate files every n minutes. ( typically ever 5 min )
16 nfcapd reads netflow v5 and v7 flows transparently. v7 flows are
17 converted into v5 flows. You need one nfcapd process for each netflow
18 stream.
19
20 nfdump - netflow dump.
21 Reads the netflow data from the files stored by nfcapd. It's syntax is
22 similar to tcpdump. If you like tcpdump you will like nfdump.
23 Displays netflow data and creates top N statistics of flow, bytes,
24 packets and IP addresses.
25
26 nfprofile - netflow profiler.
27 Reads the netflow data from the files stored by nfcapd. Filters the
28 netflow data according to the specified filter sets ( profiles ) and
29 stores the filtered data into files for later use.
30
31 nfreplay - netflow replay
32 Reads the netflow data from the files stored by nfcapd and sends it
33 over the network to another host.
34
35 nfclean.pl - cleanup old data
36 Sample script to cleanup old data. You may run this script every
37 hour or so.
38
39 ft2nfdump - read flow-tools format - Optional tool
40 ft2nfdump acts as a pipe converter for flow-tools data. It allows
41 to read any flow-tools data and process and save it in nfdump format.
42
43
44 Principle of Operation:
45 -----------------------
46 The goal of the design is to able to analyze netflow data from
47 the past as well as to track interesting traffic patterns
48 continuously. The amount of time back in the past is limited only
49 by the disk storage available for all the netflow data. The tools
50 are optimized for speed for efficient filtering. The filter rules
51 should look familiar to the syntax of tcpdump ( pcap compatible ).
52
53 All data is stored to disk, before it gets analyzed. This separates
54 the process of storing and analyzing the data.
55
56 The data is organized in a time based fashion. Every n minutes
57 - typically 5 min - nfcapd rotates and renames the output file
58 with the timestamp nfcapd.YYYYMMddhhmm of the interval e.g.
59 nfcapd.200407110845 contains data from July 11th 2004 08:45 onward.
60 Based on a 5min time interval, this results in 288 files per day.
61
62 Analyzing the data can be done for a single file, or by concatenating
63 several files for a single output. The output is either ASCII text
64 or binary data, when saved into a file, ready to be processed again
65 with the same tools.
66
67 You may have several netflow sources - let's say 'router1' 'router2'
68 and so on. The data is organized as follows:
69
70 /flow_base_dir/router1
71 /flow_base_dir/router2
72
73 which means router1 and router2 are subdirs of the flow_base_dir.
74 For each of the netflow sources you have to start an nfcpad process:
75
76 nfcapd -w -D -l /flow_base_dir/router1 -p 23456
77 nfcapd -w -D -l /flow_base_dir/router2 -p 23457
78
79 Security: none of the tools requires root privileges, unless you have
80 a port < 1024. However, there is no access control mechanism in nfcapd.
81 It is assumed, that host level security is in place to filter the
82 proper IP addresses.
83
84 See the manual pages or use the -h switch for details on using
85 each of the programs. For any questions send email to haag@switch.ch
86
87 Configure your router to export netflow. See the relevant documentation
88 for your model.
89
90 A generic Cisco sample configuration enabling NetFlow on an interface:
91
92 interface fastethernet 0/0
93 ip route-cache flow
94
95 To tell the router where to send the NetFlow data, enter the following
96 global configuration command:
97
98 ip flow-export <ip-address> <udp-port>
99 ip flow-export version 5
100
101 ip flow-cache timeout active 5
102
103 This breaks up long-lived flows into 5-minute segments. You can choose
104 any number of minutes between 1 and 60;
105
106 See the relevant documentation for a full description of netflow commands
107
108 Note: Netflow version v5 and v7 have 32 bit counter values. The number of
109 packets or bytes may overflow this value, within the flow-cache timeout
110 on very busy routers. To prevent overflow, you may consider to reduce the
111 flow-cache timeout to lower values. All nfdump tools use 64 bit counters
112 internally, which means, all aggregated values are correctly reported.
113
114 The binary format of the data files is similar to the v5 netflow format
115 except the date fields, which are converted into UNIX time format. For
116 speed reasons the binary format is machine architecture dependent, and
117 as such can not be exchanged between little and big endian systems.
118
119 Flow-tools compatibility
120 ------------------------
121 When building with configure option --enable-ftconv, the flow-tools converter
122 is included. Using this converter, any flow-tools created data can be read
123 and processed and stored by nfdump.
124
125 Example:
126
127 flow-cat [options] | ft2nfdump | nfdump [options]
128
129
130 See the INSTALL file for installation details.

785 Usage: $0 [OPTION]... [VAR=VALUE]...
786
787 To assign environment variables (e.g., CC, CFLAGS...), specify them as
788 VAR=VALUE. See below for descriptions of some of the useful variables.
789
790 Defaults for the options are specified in brackets.
791
792 Configuration:
793 -h, --help display this help and exit
794 --help=short display options specific to this package
795 --help=recursive display the short help of all the included packages
796 -V, --version display version information and exit
797 -q, --quiet, --silent do not print \`checking...' messages
798 --cache-file=FILE cache test results in FILE [disabled]
799 -C, --config-cache alias for \`--cache-file=config.cache'
800 -n, --no-create do not create output files
801 --srcdir=DIR find the sources in DIR [configure dir or \`..']

812 By default, \`make install' will install all the files in
813 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
814 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
815 for instance \`--prefix=\$HOME'.

855 Some influential environment variables:
856 CC C compiler command
857 CFLAGS C compiler flags
858 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
859 nonstandard directory <lib dir>
860 CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
861 headers in a nonstandard directory <include dir>
862 CPP C preprocessor
863
864 Use these variables to override the choices made by `configure' or to help
865 it to find libraries and programs with nonstandard names/locations.

5 .B ft2nfdump [options]
6 .SH DESCRIPTION
7 .B ft2nfdump
8 is the flow-tools converter program to read, convert and store netflow
9 data, created with the flow-tools package. It works either as a pipe filter
10 or reads flow-tools data format directly from file and exports nfdump data format
11 at stdout.
12
13 .SH OPTIONS
14 .TP 3
15 .B -r <flow-tools-file>
16 Read flow-tools formated netflow data from file \fIflow-tools-file.
17 Default: Read from stdin.
18 .TP 3
19 .B -E
20 Print raw netflow records to stdout. This option is for debugging purpose
21 only, to see any incoming netflow data. Compatible to option -E in nfcapd.
22 .TP 3
23 .B -V
24 Print ft2nfdump version and exit.
25 .TP 3
26 .B -h
27 Print help text on stdout with all options and exit.

1 .SH NAME
2 nfcapd \- netflow capture daemon
3 .SH SYNOPSIS
4 .HP 5
5 .B nfcapd [options]
6 .SH DESCRIPTION
7 .B nfcapd
8 is the netflow capture daemon of the nfdump tools. It reads netflow
9 data from the network and stores it into files. The output file
10 is automatically rotated and renamed every n minutes - typically
11 5 min - according the timestamp YYYYMMddhhmm of the interval e.g.
12 nfcapd.200407110845 contains the data from July 11th 2004 08:45 onward.
13 Additionally a file named nfcapd.200407110845.stat is created which
14 contains an ASCII readable statistical summary of the data. At the
15 end of every interval you may run any external programm, for example
16 nfprofile, which allows you to process the data.
17 .P
18 Netflow version v5 and v7 are transparently supported.
19
20 .SH OPTIONS
21 .TP 3
22 .B -p \fIportnum
23 Specifies the port number to listen. Default port is 9995
24 .TP 3
25 .B -b \fIIPaddr
26 Specifies the IP address to bind for listening. Default is any
27 available IPv4 interface.
28 .TP 3
29 .B -l \fIdirectory
30 Specifies the directory to store the output files. Default is /var/tmp
31 .TP 3
32 .B -t \fIinterval
33 Specifies the time interval in seconds to rotate files. The default value
34 is 300s ( 5min ).
35 .TP 3
36 .B -w
37 Align file rotation with next n minute ( specified by -t ) interval.
38 Example: If interval is 5 min, sync at 0,5,10... wall clock minutes
39 Default: no alignment.
40 .TP 3
41 .B -x \fIcmd
42 Run command \fIcmd\fR at the end of every interval, when a new file
43 becomes available. The following command expansion is available:
44 .PD 0
45 .RS 4
46 %f Replaced by the file name e.g nfcapd.200407110845.
47 .P
48 %d Replaced by the directory where the file is located.
49 .P
50 %t Replaced by the time ISO format e.g. 200407110845.
51 .P
52 %u Replaced by the UNIX time format.
53 .P
54 %i Replaced ident string given by -I
55 .RE
56 .PD
57 .TP 3
58 .B -P \fIpidfile
59 Specify name of pidfile. Default is no pidfile.
60 .TP 3
61 .B -D
62 Daemon mode: fork to background and detach from terminal.
63 Nfcapd terminates on signal TERM, INT and HUP.
64 .TP 3
65 .B -I \fIIdentString
66 Specifies an ident string, which describes the source e.g. the
67 name of the router. This string is put into the stat file to identify
68 the source. Default is 'none'.
69 .TP 3
70 .B -B \fIbufflen
71 Specifies the socket input buffer length in bytes. For high volume traffic
72 ( near GB traffic ) it is recommended to set this value as high as possible
73 ( typically > 100k ), otherwise you risk to lose packets. The default
74 is OS ( and kernel ) dependent.
75 .TP 3
76 .B -E
77 Print netflow records in nfdump raw format to stdout. This option is for
78 debugging purpose only, to see how incoming netflow data is processed and stored.
79 .TP 3
80 .B -V
81 Print nfcapd version and exit.
82 .TP 3
83 .B -h
84 Print help text to stdout with all options and exit.
85 .SH "RETURN VALUE"
86 Returns 0 on success, or 255 if initialization failed.
87 .SH "LOGGING"
88 nfcapd logs to syslog with SYSLOG_FACILITY LOG_DAEMON
89 For normal operation level 'warning' should be fine.
90 More information is reported at level 'info' and 'debug'.
91 .P
92 A small statistic about the collected flows, as well as errors
93 are reported at the end of every interval to syslog with level 'info'.
94 .SH "EXAMPLES"
95 nfcapd -w -D -l /netflow/spool/router1 -p 23456 -B 128000 -I router1 -x '/path/nfprofile -p /to/profile/dir -s router1 -r %d/%f' -P /var/run/nfcapd/nfcapd.router1
96 .SH NOTES
97 Setting the socket buffer size is system dependent. When starting up,
98 nfcapd returns the number of bytes the buffer was actually set. This
99 is done by reading back the buffer size and may differ from what you
100 requested.
101 .P
102 Nfdump tools version 1.4 support netflow v5 and v7 transparently.
103 .SH "SEE ALSO"
104 nfdump(1), nfprofile(1), nfreplay(1)
105 .SH BUGS
106 I only found the second last bug. Please report the last one back to me.

1 .SH NAME
2 nfdump \- netflow display and analyze program
3 .SH SYNOPSIS
4 .HP 5
5 .B nfdump [options] [filter]
6 .SH DESCRIPTION
7 .B nfdump
8 is the netflow display and analyzing program of the nfdump tool set.
9 It reads the netflow data from files stored by nfcapd and processes
10 the flows according the options given. The filter syntax is comparable
11 to tcpdump and extended for netflow data. Nfdump can also display many
12 different top N flow and flow element statistics.
13
14 .SH OPTIONS
15 .TP 3
16 .B -r \fIinputfile
17 Read input data from \fIinputfile\fR. Default is read from stdin.
18 .TP 3
19 .B -R \fIexpr
20 Read input from a sequence of concatenated files. The \fIexpr\fR
21 may be one of:
22 .PD 0
23 .RS 4
24 /any/\fIdir\fR Read all files in directory \fIdir\fR.
25 .P
26 /dir/\fIfile\fR Read all files beginning with \fIfile\fR.
27 .P
28 /dir/\fIfile1:file2\fR Read all files from \fIfile1\fR to \fIfile2\fR.
29 .RE
30 .PD
31 .TP 3
32 .B -M \fIexpr
33 Read input from multiple directories. The \fIexpr\fR looks like:
34 \fI/any/path/to/dir1:dir2:dir3\fR etc. and will be expanded to the
35 directories: \fI/any/path/to/dir1\fR, \fI/any/path/to/dir2\fR and
36 \fI/any/path/to/dir3\fR Any number of colon separated directories may
37 be given. The files to read are specified by -r or -R and are expected
38 to exist in all the given directories. The options -r and -R must
39 not contain any directory part when used in conjunction with -M.
40 .TP 3
41 .B -m
42 Sort the netflow records according the date first seen. This option is
43 usually only useful in conjunction with -M, when netflow records are
44 read from different sources, which are not necessarily sorted.
45 .TP 3
46 .B -w \fIoutputfile
47 If specified writes binary netflow records to \fIoutputfile\fR ready
48 to be processed again with nfdump. The default output is ASCII on
49 stdout.
50 .TP 3
51 .B -f \fIfilterfile
52 Reads the filter syntax from \fIfilterfile\fR. Note: Any filter specified
53 directly on the command line takes precedence over -f.
54 .TP 3
55 .B -t \fItimewin
56 Process only flows, which fall in the time window \fItimewin\fR, where
57 \fItimewin\fR is YYYY/MM/dd.hh:mm:ss[-YYYY/MM/dd.hh:mm:ss]. Any parts of
58 the time spec may be omitted e.g YYYY/MM/dd expands to
59 YYYY/MM/dd.00:00:00-YYYY/MM/dd.23:59:59 and processes all flow from a
60 given day. The time window may also be specified as +/- n. In this case
61 it is relative to the beginning or end of all flows. +10 means the first
62 10 seconds of all flows, -10 means the last 10 seconds of all flows.
63 .TP 3
64 .B -c \fInum
65 Limit number of records to process to the first \fInum\fR flows.
66 .TP 3
67 .B -a
68 Aggregate netflow data. Aggregation is done at connection level.
69 .TP 3
70 .B -A \fIfields
71 Aggregate netflow data using the specified fields, where fields is a ','
72 separated list out of \fIsrcip dstip srcport dstport\fR. The default is using
73 all fields: \fIsrcip,dstip,srcport,dstport\fR. Only flows of the same protocol
74 are aggregated.
75 .TP 3
76 .B -S
77 Compatibility option with pre 1.4 nfdump. Is equal to \fI-s record/packets/bytes\fR.
78 .TP 3
79 .B -s \fIstatistic[/orderby]
80 Generate the Top N flow or flow element statistic. \fIstatistic\fR can be:
81 .PD 0
82 .RS 5
83 record Statistic about aggregated netflow records.
84 .P
85 srcip Statistic about source IP addresses
86 .P
87 dstip Statistic about destination IP addresses
88 .P
89 ip Statistic about any (source or destination) IP addresses

255 .SH "FILTER
256 "
257 The filter syntax is similar to the well known pcap library used by tcpdump.
258 The filter can be either specified on the command line after all options or
259 in a separate file. It can span several lines. Anything after a '#' is treated as a
260 comment and ignored to the end of the line. There is virtually no limit in
261 the length of the filter expression. All keywords are case independent.
262 .P Syntax
263 Any filter consists of one or more expressions \fIexpr\fR. Any number of \fIexpr\fR
264 can be linked together:

381 .SH NOTES
382 Generating the statistics for data files of a few hundred MB is no problem. However
383 be careful if you want to create statistics of several GB of data. This may consume a lot
384 of memory and can take a while. Also, anonymizing IP addresses is time consuming and uses
385 a lot of CPU power, which reduces the number of flows per second. Therefore anonymizing
386 takes place only, when flow records are printed or written to files. Any internal flow
387 processing takes place using the original IP addresses.

1 .SH NAME
2 nfprofile \- netflow profiler
3 .SH SYNOPSIS
4 .HP 5
5 .B nfprofile [options]
6 .SH DESCRIPTION
7 .B nfprofile
8 is the netflow profiler program of the nfdump tool set.
9 It reads the netflow data from the files stored by nfcapd and creates
10 the corresponding output files for every profile available in the
11 profile base directory. The filter syntax is equivalent to nfdump.
12 See the nfdump(1) man page for a detailed description of the filter
13 syntax.
14
15 .SH OPTIONS
16 .TP 3
17 .B -r \fIinput file
18 Read input data from \fIinput file\fR. Required option. The name of the
19 output file is the same as the name as \fIinput file\fR and stored in the
20 appropriate profile directory.
21 .TP 3
22 .B -t \fItimewin
23 Process only flows, which fall in the time window \fItimewin\fR, where
24 \fItimewin\fR is YYYY/MM/dd.hh:mm:ss[-YYYY/MM/dd.hh:mm:ss]. Any parts of
25 the time spec may be omitted e.g YYYY/MM/dd expands to
26 YYYY/MM/dd.00:00:00-YYYY/MM/dd.23:59:59 and processes all flow from a
27 given day.
28 .TP 3
29 .B -f \fIfilter
30 Name of the filter file. This file is stored in the \fIprofile directory\fR
31 for each profile. The default name is filter.txt. If no filter file
32 is found, this profile is not processed.
33 .TP 3
34 .B -p \fIprofile base directory
35 Defines the base directory, where all he profiles are stored. This is a
36 required parameter. Each directory in the \fIprofile base directory\fR is
37 considered to be a profile, and therefore a \fIprofile directory\fR.
38 Directory names starting with a '.' are ignored.
39 .TP 3
40 .B -s \fIprofile subdirectory
41 Defines the \fIprofile subdirectory.
42 Each \fIprofile directory\fR may have several \fIprofile subdirectories\fR
43 according to the number of netflow sources. The filtered output files are
44 stored in this subdirectory: \fIprofile base directory/profile subdirectory.
45 .TP 3
46 .B -Z
47 Check the filter syntax of all profiles and exit. Sets the return value
48 accordingly.
49 .TP 3
50 .B -V
51 Print nfdump version and exit.
52 .TP 3
53 .B -h
54 Print help text on stdout with all options and exit.
55 .SH "RETURN VALUE"
56 Returns
57 .PD 0
58 .RS 4
59 0 No error. \fn
60 .P
61 255 Initialization failed.
62 .P
63 254 Error in filter syntax.

1 .SH NAME
2 nfreplay \- netflow replay program
3 .SH SYNOPSIS
4 .HP 5
5 .B replay [options] [filter]
6 .SH DESCRIPTION
7 .B nfreplay
8 is the netflow replay program of the nfdump tool set.
9 It reads the netflow data from the files stored by nfcapd. The filter
10 syntax is equivalent to nfdump. If a filter is supplied, only the
11 matching flows are sent. See the nfdump(1) man page for a detailed
12 description of the filter syntax. All records are sent as netflow version 5.
13
14 .SH OPTIONS
15 .TP 3
16 .B -i \fIIP address
17 Send all flows to this IP address. Default is localhost 127.0.0.1
18 .TP 3
19 .B -p \fIport
20 Send all fows to this port on the remote side. Default is 9995.
21 .TP 3
22 .B -d \fIusec
23 Delay each record bei \fIusec\fR mirco seconds, to avoid overrun on the remote
24 side. Default is 10.
25 .TP 3
26 .B -b \fIbuffersize
27 Set send buffer size in bytes. Usefull for large data to transfer. Default is
28 system dependent.
29 .TP 3
30 .B -r \fIinputfile
31 Read input data from \fIinputfile\fR. Default is read from stdin.
32 .TP 3
33 .B -t \fItimewin
34 Send only flows, which fall in the time window \fItimewin\fR, where
35 \fItimewin\fR is YYYY/MM/dd.hh:mm:ss[-YYYY/MM/dd.hh:mm:ss]. Any parts of
36 the time spec may be omitted e.g YYYY/MM/dd expands to
37 YYYY/MM/dd.00:00:00-YYYY/MM/dd.23:59:59 and sends all flow from a
38 given day.
39 .TP 3
40 .B -c \fInum
41 Limit number of records to send to the first \fInum\fR flows.
42 .TP 3
43 .B -V
44 Print nfreplay version and exit.
45 .TP 3
46 .B -h
47 Print help text on stdout with all options and exit.
48 .SH "RETURN VALUE"
49 Returns
50 .PD 0
