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.
