NAME

       nfreplay - netflow replay program

SYNOPSIS

       nfreplay [options] [filter]

DESCRIPTION

       nfreplay  is  the netflow replay program of the nfdump tool set.  It reads data from files stored by nfcapd and sents the netflow data to a
       host or a multicat group. The filter syntax is equivalent to nfdump. If a filter is supplied, only the matching flows are  sent.   See  the
       nfdump(1) man page for a detailed description of the filter syntax. All records are sent as netflow version 5.

OPTIONS

       -H remotehost
	  Send all flows to this remote host. Accepts a symbolic name or a IPv4/IPv6 IP address.  Defaults to IPv4 localhost 127.0.0.1.

       -j mcastgroup
	  Join this multicast group and send all flows to this group host. Accepts a symbolic name or multicast IPv4/IPv6 IP address.

       -p port
	  Send all flows to this port on the remote side. Default is 9995.

       -4 Forces  nfreplay  to	send  flows  to  a IPv4 address only. Can be used together with -i if the remote host has an IPv4 and IPv6 address
	  record.

       -6 Forces nfreplay to send flows to a IPv6 address only. Can be used together with -i if the remote host  has  an  IPv4	and  IPv6  address
	  record.

       -v num
	  Send flows as netflow version num. 5 and 9 are supported. The default is sending the flows as netflow version 5. In version 5 mode, IPv6
	  flows, are skipped and 64bit counters are truncated to 32bit.

       -d usec
	  Delay each record by usec mirco seconds, to avoid overrun on the remote side. Default is 10.

       -b buffersize
	  Set send buffer size in bytes. Useful for large data to transfer. Default is system dependent.

       -r inputfile
	  Read input data from inputfile. Default is read from stdin.

       -t timewin
	  Send only flows, which fall in the time window timewin, where timewin is YYYY/MM/dd.hh:mm:ss[-YYYY/MM/dd.hh:mm:ss].  Any  parts  of  the
	  time spec may be omitted e.g YYYY/MM/dd expands to YYYY/MM/dd.00:00:00-YYYY/MM/dd.23:59:59 and sends all flow from a given day.

       -c num
	  Limit number of records to send to the first num flows.

       -V Print nfreplay version and exit.

       -h Print help text on stdout with all options and exit.

RETURN VALUE

       Returns
	   0   No error.
	   255 Initialization failed.
	   254 Error in filter syntax.
	   250 Internal error.
