[c-nsp] Announcement: FlowViewer v4.1

[Joe Loiacono]

FlowViewer 4.1 provides a convenient web-based user interface to two 
popular open-source netflow collector/analyzers: flow-tools and SiLK. 
After a long wait, SiLK v3.7.1 was released to the general public last 
week. The inclusion of the underlying SiLK tool set enables FlowViewer 
users to continue to use the tool with the newer IPFIX netflow data 
protocol (e.g., Cisco v9, Flexible Netflow.)

FlowViewer provides the user with tools to analyze, graph, and track (ala 
MRTG) filtered subsets of network traffic. One of the primary benefits of 
the new version is the ability to analyze and track IPv6 flows.

FlowViewer 4.1 is available from SourceForge at
