I am getting a traceback in the connection summary emails rather than useful information. I didn’t have the Python SubnetTree package installed when I built, installed, and first started Zeek but have since installed it on the management/logger and all sensors. I restarted Zeek but am still seeing the traceback. Suggestions on where to look next?

> I am getting a traceback in the connection summary emails rather than useful information. I didn't have the Python SubnetTree package installed when I built, installed, and first started Zeek but have since installed it on the management/logger and all sensors. That usually should get built/installed as part of the default Zeek installation and you don't have to independently install it. > I restarted Zeek but am still seeing the traceback. Just double-checking: the message didn't change after independently installing pysubnettree ? That would make sense since I expect there's some explicit PYTHONPATH that's always picking up the version installed with Bro/Zeek rather than the independently installed version. You could try comparing:     python -c "import SubnetTree" versus:     PYTHONPATH=/usr/local/bro/lib/broctl python -c "import SubnetTree" as a test of whether either version successfully gets imported. > Suggestions on where to look next? Probably would help to get more details/info that could help reproduce the error. What Zeek/Bro version ? What operating system ? What Python version and what `swig -version` ? The full `./configure` command you used when building Zeek/Bro and its output may be most helpful. A guess is that the configuration failed to detect a valid/consistent Python and somehow that botched the build/install of pysubnettree. - Jon ---

It looks like the two versions of python are installed. That could be the problem as Python 2.7 is found for the interpreter but 3.5 is found for libraries. The following lines are taken from the configuration output: … – Found PythonInterp: /usr/bin/python (found version “2.7.13”) … – Found PythonLibs: /usr/lib/x86\_64-linux-gnu/[libpython3.5m.so](http://libpython3.5m.so) (found version “3.5.3”) – Found PythonDev: /usr/include/python3.5m To test the theory, I will rebuild explicitly specifying the version of python: $ CC=clang CXX=clang++ ./configure --with-python=/usr/bin/python --with-python-lib=/usr/lib/x86\_64-linux-gnu/[libpython2.7.so](http://libpython2.7.so) --with-python-inc=/usr/include/python2.7 I’ll let you know how it turns out once the build finishes and I am able to test it.

Was it the same traceback before? The broctl bundles subnettree, so you should have already had it in the form of these 2 files: /usr/local/bro/lib/broctl/\_SubnetTree.so /usr/local/bro/lib/broctl/SubnetTree.py now it looks like you have 2 incompatible versions of it installed that are conflicting with each other. ---
