(I apologize for incorrectly posting this earlier on the bro-dev list  
which seems to be intended only for the Bro-Tracker bot to post to.)

Hi all:

I am seeing errors like this every time the connection summary script runs:

python:/usr/local/bro/lib/broctl/\_SubnetTree.so: undefined symbol '\_\_inet\_addr'  
python:/usr/local/bro/lib/broctl/\_SubnetTree.so: undefined symbol '\_\_inet\_aton'  
Traceback (most recent call last):  
File "/usr/local/bro/bin/trace-summary", line 19, in \<module\>  
import SubnetTree  
File "/usr/local/bro/lib/broctl/SubnetTree.py", line 7, in \<module\>  
import \_SubnetTree  
ImportError: Cannot load specified object  
0.20 real 0.00 user 0.00 sys

Incidentally, I get the same kind of linker errors at bro startup that  
were seen on OpenBSD with bro a couple of years ago:

# /usr/local/bro/bin/bro --version  
/usr/local/bro/bin/bro:/usr/lib/libc.so.60.1:

# uname -a  
OpenBSD \<hostname\> 5.0 GENERIC#43 i386  
# pkg\_info | grep libbind  
libbind-9.4.2 BIND 8 compatible stub resolver library

Is this a case of some kind of incompatibility between the libc and  
libbind resolver functions?

Thanks,

Heh, it's actually not. That list is for development discussion but we use the tracker heavily enough that it can certainly get overwhelmed with tracker messages if you aren't filtering those to a separate mail box. 🙂

We're going to begin doing continuous integration (automated building and testing after every commit) of the Bro source code soon and the plan currently is to also do these build/test cycles on a range of operating systems. I think that OpenBSD is going to be one of the ones we test so hopefully our OpenBSD support will be regularly tested (which it currently isn't) so we can prevent regressions from popping up.

I have no clue, Jon Siwek may know the answer though.

I saw some discussion in the mailing list archive about those linker warnings, too, and I think it maybe not be a regression, but the original warnings were never resolved.

That's my guess is that something is out of sync between those two -- compiling and running a simple test program that links against libbind will yield the same warnings, so it might be an issue that the OpenBSD ports mailing list or libbind package maintainer would better help.
