 Description: Very fast DDoS analyzer with sflow/netflow/mirror support
- FastNetMon - A high performance DoS/DDoS attack sensor.
+ FastNetMon is a very high performance distributed denial-of-service attack
+ (DDoS attack) detector built on top of multiple packet capture engines:
+ NetFlow, IPFIX, sFLOW.
+ .
+ It can detect hosts in your networks sending or receiving large volumes of
+ packets/bytes/flows per second. It can call an external script to notify you,
+ switch off a server, or blackhole the client.
+ .
+ To enable sFLOW, simply specify IP of the server running FastNetMon and specify
+ (configurable) port 6343. To enable netflow, simply specify IP of the server
+ running FastNetMon and specify (configurable) port 2055.
