10
12 nfreplay is the netflow replay program of the nfdump tool set. It
13 reads data from files stored by nfcapd and sents the netflow data to a
14 host or a multicat group. The filter syntax is equivalent to nfdump. If
15 a filter is supplied, only the matching flows are sent. See the
16 nfdump(1) man page for a detailed description of the filter syntax. All
17 records are sent as netflow version 5.
18
19
21 -H remotehost
22 Send all flows to this remote host. Accepts a symbolic name or a
23 IPv4/IPv6 IP address. Defaults to IPv4 localhost 127.0.0.1.
24
25 -j mcastgroup
26 Join this multicast group and send all flows to this group host.
27 Accepts a symbolic name or multicast IPv4/IPv6 IP address.
28
29 -p port
30 Send all flows to this port on the remote side. Default is 9995.
31
32 -4 Forces nfreplay to send flows to a IPv4 address only. Can be used
33 together with -i if the remote host has an IPv4 and IPv6 address
34 record.
35
36 -6 Forces nfreplay to send flows to a IPv6 address only. Can be used
37 together with -i if the remote host has an IPv4 and IPv6 address
38 record.
39
40 -v num
41 Send flows as netflow version num. 5 and 9 are supported. The
42 default is sending the flows as netflow version 5. In version 5
43 mode, IPv6 flows, are skipped and 64bit counters are truncated to
44 32bit.
45
46 -d usec
47 Delay each record by usec mirco seconds, to avoid overrun on the
48 remote side. Default is 10.
49
50 -b buffersize
51 Set send buffer size in bytes. Useful for large data to transfer.
52 Default is system dependent.
53
54 -r inputfile
55 Read input data from inputfile. Default is read from stdin.
56
57 -t timewin
58 Send only flows, which fall in the time window timewin, where
59 timewin is YYYY/MM/dd.hh:mm:ss[-YYYY/MM/dd.hh:mm:ss]. Any parts of
60 the time spec may be omitted e.g YYYY/MM/dd expands to
61 YYYY/MM/dd.00:00:00-YYYY/MM/dd.23:59:59 and sends all flow from a
62 given day.
63
64 -c num
65 Limit number of records to send to the first num flows.
66
67 -V Print nfreplay version and exit.
68
69 -h Print help text on stdout with all options and exit.
