nfreplay — replay binary flow files as netflow version v5 or v9 to a remote host

nfreplay reads binary flow files stored by any nfdump collector and sents the flow records  to  a  remote
       host or a multicast group.

       nfreplay sends the data as netflow v5 or v9 to the remote location.

       nfreplay accepts a filter to limit the flows to be sent. The filter syntax is equivalent to nfdump.

       The options are as follows:

       -rflowfile
               Read input data from flowfile.-Hremotehost
               Send all flows to this remote host. Accepts a symbolic name or a IPv4/IPv6 IP address.

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

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

       -SSourceaddr
               Use the specified source IP address to send the flows

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

       -vversion
               Send flows as netflow version version.  Version  V5  and  v9  are  supported.  In  v5  mode,  all
               additional elements to a stadard v5 record are skipped and 64bit counters are truncated to 32bit.
               The default is v9.

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

       -Bbuffsize
               Set send buffer to buffsize size in bytes. Useful to buffer larger data transfers.

       -znum  Flows are sent with their "real distribution" acrross time (with a speed coefficient)
               -z 1 : 5 minutes of records will be sent in 5 minutes.  - z 20 : 5 minutes of record will be sent
               in 5/20 = 0.25 minutes.

       -cnum  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.
