Most of my projects are hosted at Github. Some of the more interesting ones are:
nInfo is a plugin based information gathering library. It provides a unified api for looking up information about things like ip addresses and hostnames.
netflow-indexer uses xapian to index the flat file databases used by nfdump, flow-tools, or Bro.
Current being re-written in go as flow-indexer.
http_flood is an http server that floods the client with random data. As fast as it can. It is useful as a replacement for iperf when you can’t install software on client machines.
