Hi, I wonder if someone knows a tool to use a tcpdump output for anomaly dedection. It is sometimes really time consuming when looking for identical patterns in the tcpdump output.
Check out Argus, <http://www.qosient.com/argus/>. (I recommend still using version 2, version 3 is not quite production quality yet...)
Argus is a stream analyzer, instead of a packet analyzer. You can search argus data by tcp flags, by regular expression on the data (if you enable stream data logging, which is optional), or several other options. See the argus site for more information.
