Thanks for the updates. Good to know that there will be a prototype of MODBUS support in Bro 2.2. Any estimates about the release timeline for Bro 2.2?
Can the prototype of MODBUS support also be customized to work with Bro 2.0 quickly? We are eager to experiment using Bro to monitor and analyze MODBUS/TCP traffic. :)

No, not yet. We've a prototype of Modbus support (and DNP3), which will likely make it into Bro 2.2. Nobody is working on SNMP yet though as far as I know.

The best way is to use our binpac parser generator, see here for a
Also take a look at the existing analyzers in src/*.pac.
