I just posted an updated guide.  If you run 'sudo ldconfig' it should
fix the libsfbpf error across multiple reboots.

Hi David,


I ran into two problems when I followed the installation guide you


When I tested the installation snort exited with an error:


/usr/local/snort/bin/snort: error while loading shared libraries:

libsfbpf.so.0: cannot open shared object file: No such file or directory


I found a forum post on this issue:




When I run the commands described there as root, (#
LD_LIBRARY_PATH=/usr/local/lib, # export LD_LIBRARY_PATH) Snort
initializes properly.


I have not found out how to make this change permanent, so any
suggestions on how to do this would be appreciated.


The second issue I had, was that Snortreport did not show any alerts,
only a warning that said “No data”. I think you have helped other users
with this error before cf.
When I followed the advice given here, Snort and Snortreport both work.


I installed Snort with Snortreport on a VM and only for testing
purposes. So I did not do the "Setting up the network cards" part, nor
configure the "rc.local" file to start Snort automatically. Otherwise I
followed the installation guide step by step.


I also had a brief look at the new version of Snortreport on you demo
site. I do not know how it compares to BASE in functionality or use,
since I have not come around to installing BASE yet. I am going to test
Snort with Snortreport more as I think it looks promising as a front end
to snort.
