For details on the use of the nfdump command, see the nfdump manual page (with the man nfdump command).NfSen is a web-based graphical front-end to NFdump.The SiLK Analysis Suite is an extremely popular open source command line "Swiss Army Knife" developed by CERT. Network administrators and network security personnel can use the tools in this set of swords to combine their efforts to perform exhaustive NetFlow analysis. SiLK includes a variety of tools and plug-ins.The SiLK Packing System consists of multiple applications (daemons) that capture NetFlow data and convert it into a more space-efficient file format. SiLK stores these records in service-specific binary flat files for use by the analysis suite. The files are organized in a time-based directory hierarchy. The following shows the various daemons of SiLK.flowcap: listens for flow generators and stores data into temporary files.rwflowpack: processes data received directly from the flow generator or processes data in files generated by flowcap.426 Chapter 11 Network and Host Insight TechnologiesThe data is then converted to SiLK stream record format.rwflowappend: appends the stream record to an hourly file (hourly file) organized in a time-based directory tree. o
