102                  1005 Flow-Tools tagged version 5
103
104
105       -z z_level
106              Configure compression level to  z_level. 0 is disabled (no  com‐
107              pression), 9 is highest compression.
108

EXAMPLES

110       Convert  the  cflowd  file  flows.cflowd  to the flow-tools file flows.
111       Store as Version 5 with compression level 5.
112
113       flow-import -V5 -z5 -f0 < flows.cflowd > flows
114

EXAMPLES

116       Convert the ASCII CSV data in flows.ascii  to  flow-tools  format.  The
117       ASCII data must include all fields represented by 0xFF31EF in the order
118       listed above. Store as Version 5 with no compression.
119
120       flow-import -z0 -f2 -m0xFF31EF < flows.ascii > flows
121

BUGS

123       The pcap format is a hack.
