Re: [Zeek-Dev] Writing a Protocol Analyzer Plugin
Heh.. this is what I get for not following up on a WIP merge... Try the
topic/dopheide/namespace branch of github.com/esnet/binpac_quickstart.
That should allow you to specify Demo::ConnTaste, but it will uppercase
that to Demo::CONNTASTE, which I believe was an old convention.

Many thanks for the quick responses!
I am receiving these errors:
```
error in /usr/local/bro/share/bro/base/init-bare.bro, line 1: plugin
Demo::ConnTaste is not available
fatal error in /usr/local/bro/share/bro/base/init-bare.bro, line 1:
Failed to activate requested dynamic plugin(s).
```
After executing these commands:
```
git clone --recursive https://github.com/zeek/zeek.git
cd zeek
./configure
make
DIST=`pwd`
cd aux/bro-aux/plugin-support
./init-plugin -u ./conn-taste Demo ConnTaste
BRO_PLUGIN_PATH=`pwd`
cd ${DIST}
cd ../
git clone https://github.com/esnet/binpac_quickstart.git
cd binpac_quickstart
pip install docopt jinja2
./start.py ConnTaste "Connection Byte Offset Tasting"
${BRO_PLUGIN_PATH}/conn-taste/ --tcp --buffered --plugin
cd ${BRO_PLUGIN_PATH}/conn-taste
./configure --bro-dist=${DIST}
make
cd ${DIST}
./configure
make
make install
bro -NN Demo::ConnTaste
```
I'm guessing there is some environment variable I am missing as I tried
zeek/testing/btest/plugins/protocol.bro as Robin suggested and the
@TEST-EXEC statements worked as expected.

Re: [Zeek-Dev] Writing a Protocol Analyzer Plugin
Okay, with your original line for quickstart, this works rather than
Demo::ConnTaste.
bash-3.2# /usr/local/bro/bin/bro -NN Bro::CONNTASTE
Bro::CONNTASTE - This thing analyzer (dynamic, no version information)
[Analyzer] CONNTASTE (ANALYZER_CONNTASTE, enabled)
[Event] conntaste_event
So we've got some plugin naming issues to deal with, which I hope to work
out tomorrow. It shouldn't be about reinventing the universe, binpac is
hard enough. :)

Oops! Sorry about that. Try this one:

That has a '--plugin' option. That will at least get the boilerplate
stuff built, and then you can start digging into the protocol specifics.

I'm sure there is at least one other Carl Sagan fan on list. I feel like if

Re: [Zeek-Dev] Writing a Protocol Analyzer Plugin
I tried changing the name provided to the setup script as suggested. Doing
so gives me many errors when I try to ./configure the plugin from within
the conn-taste/ directory. CMake states that DEMO::CONNTASTE-events.bif is
"reserved or not valid for for certain CMake features". It complains about
many of the file names.
Additionally, all the files in conn-taste/src/ look like
DEMO::CONNTASTE.cc :(

Many thanks for the quick responses!
I am receiving these errors:
```
error in /usr/local/bro/share/bro/base/init-bare.bro, line 1: plugin
Demo::ConnTaste is not available
fatal error in /usr/local/bro/share/bro/base/init-bare.bro, line 1:

```
After executing these commands:
```
git clone --recursive https://github.com/zeek/zeek.git
cd zeek
./configure
make
DIST=`pwd`
cd aux/bro-aux/plugin-support
./init-plugin -u ./conn-taste Demo ConnTaste
BRO_PLUGIN_PATH=`pwd`
cd ${DIST}
cd ../
git clone https://github.com/esnet/binpac_quickstart.git
cd binpac_quickstart
pip install docopt jinja2
./start.py ConnTaste "Connection Byte Offset Tasting"
${BRO_PLUGIN_PATH}/conn-taste/ --tcp --buffered --plugin
cd ${BRO_PLUGIN_PATH}/conn-taste
./configure --bro-dist=${DIST}
make
cd ${DIST}
./configure
make
make install
bro -NN Demo::ConnTaste
```
I'm guessing there is some environment variable I am missing as I tried
zeek/testing/btest/plugins/protocol.bro as Robin suggested and the
@TEST-EXEC statements worked as expected.
