yes.. it could be.  If you have no files there then you can comment those out.

And you can use ipvar for ipv4 only.. that's not a problem, I jsut
didn't know if you have var or ipvar before and if you planned on
using ipv6 (that preprocessor was v6)

Without looking at the Google's, normally preprocessor errors are missing
files.  Look in your snort conf and make sure the paths to the preprocessors
are correct.

And if you are using ipv6 addresses make sure you use ipvar vs var in snort
conf.


Hmm.... this is interesting.

I reverted my config back from ipvar to var since I'm using IPv4.

The libraries are setup as such:

# path to dynamic preprocessor libraries
dynamicpreprocessor directory /usr/local/lib/snort_dynamicpreprocessor/

# path to base preprocessor engine
dynamicengine /usr/local/lib/snort_dynamicengine/libsf_engine.so

# path to dynamic rules libraries
dynamicdetection directory /usr/local/lib/snort_dynamicrules


of which they are all there:

# ls /usr/local/lib | grep snort
snort_dynamicengine
snort_dynamicpreprocessor
snort_dynamicrules


The rules have been setup as such:

var RULE_PATH ./rules
var SO_RULE_PATH ./so_rules
var PREPROC_RULE_PATH ./preproc_rules


All the *rules files and directories reside within /etc/snort/ - I have also
attempted to put the full dir path too; /etc/snort/rules etc...

- which didn't yield any difference.


I'm not sure what's going on, I don't have anything in the dynamicrules or
dynamicpreprocessor folders though! Could this be the issue?

I've just compiled and installed Barnyard2 now and currently working on
the integration with snort 2.9.3.1.

I just wonder if I will need to do anything different for my BASE
setup??


No, it uses the same schema and should continue to work as expected,
the main difference being that its barnyard2 that feeds the database.

Thanks for the response!

I know I should ask this in a new Subject Heading however I'm getting this
error while trying to start Snort:
