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).
