flow-send(1)                                                      flow-send(1)

NAME

       flow-send — Transmit flow data with the NetFlow protocol.

SYNOPSIS

       flow-send   [-h]    [-d  debug_level]   [-m  privacy_mask]   [-s]   [-x
       xmit_delay]  [-V pdu_version] localip/remoteip/port

DESCRIPTION

       The flow-send utility is used to transmit flows in NetFlow format to  a
       collector specified by localip/remoteip/port.

OPTIONS

       -d debug_level
                 Enable debugging.

       -h        Display help.

       -s        Enable spoofing of source IP address.

       -m privacy_mask
                 Apply  privacy_mask  to the source and destination IP address
                 of flows.  For example a privacy_mask of 255.255.255.0  would
                 convert  flows  with source/destination IP addresses 10.1.1.1
                 and 10.2.2.2 to 10.1.1.0 and 10.2.2.0 respectively.

       -V pdu_version
                 Use pdu_version format when transmitting.

       -x xmit_delay
                 Configure a microsecond transmit delay between packets.  This
                 may be necessary in some configurations to prevent a transmit
                 buffer overrun.

EXAMPLES

       Transmit all flows in the directory /flows/krc4  to  the  collector  at
       10.0.0.1 listening on port 9500.

         flow-cat /flows/krc4 | flow-send 0/10.0.0.1/9500

       Generate a test pattern of version 7 flows and send them to a collector
       at 10.0.0.1 listening on port 9500.

         flow-gen -V7 | flow-send 0/10.0.0.1/9500

BUGS

       It is not currently possible to convert between the aggregated  formats
       (8.x) and the non aggregated formats (1,5,6,7).
