NAME

flow-import - Import flows into flow-tools from other NetFlow packages.

SYNOPSIS

flow-import [ -h ] [ -b big|little ] [ -d debug_level ] [ -f format ] [ -m mask_fields ] [ -V pdu_version ] [ -z z_level ]

DESCRIPTION

The flow-import utility will convert data from cflowd and ASCII CSV files into flow-tools format.

OPTIONS

-b big|little
Byte order of output.
-d debug_level
Enable debugging.
-f format
Export format. Supported formats are:
   0 cflowd
   2 ASCII CSV
   3 Cisco NFCollector
 
 
-h
Display help.
-m mask_fields
Select fields for cflowd and ASCII formats. The mask_fields is built from a bitwise OR of the following:
     UNIX_SECS       0x0000000000000001LL
     UNIX_NSECS      0x0000000000000002LL

The default value is all fields applicable to the pdu_version.

-V pdu_version
Use pdu_version format output.
     1    NetFlow version 1 (No sequence numbers, AS, or mask)
     5    NetFlow version 5
     6    NetFlow version 6 (5+ Encapsulation size)

-z z_level
Configure compression level to z_level. 0 is disabled (no compression), 9 is highest compression.

EXAMPLES

Convert the cflowd file flows.cflowd to the flow-tools file flows. Store as Version 5 with compression level 5.

flow-import -V5 -z5 -f0 < flows.cflowd > flows

EXAMPLES

Convert the ASCII CSV data in flows.ascii to flow-tools format. The ASCII data must include all fields represented by 0xFF31EF in the order listed above. Store as Version 5 with no compression.

flow-import -z0 -f2 -m0xFF31EF < flows.ascii > flows

BUGS

The pcap format is a hack.
