In case anyone is interested you can grab the current so rules from
the current VRT rulepack.

so_rules/bad-traffic.c
so_rules/dos.c
so_rules/exploit.c
so_rules/p2p.c

Cheers,
Justin

No problem.

Nope, it's just an example.

Also, if you don't have any dynamic rules enabled you don't need the dynamic
engine turned on.


Cheers,
Justin

Ahh thanks. So its commented out by default and at some point the
comment was removed from my file.

So Sourcefire isn't going to create and distribute this example .SO file?

It looks like you are trying to load an example dynamic rule. This is
purely an example for those who want to create an example rule it is not
meant to be loaded.

All,

Has anyone here moved from Snort 2.6.0.x to Snort 2.6.1 yet? By default,
the following dynamic directories are created in /usr/local/lib:

/usr/local/lib/snort_dynamicengine
/usr/local/lib/snort_dynamicpreprocessor

However, when enabling all of the options in the new DNS Preprocessor it
causes Snort to fail with the error:

Rule application order:

->activation->dynamic->pass->drop->sdrop->reject->alert->log
Log directory =

/usr/local/appliedwatch/agent/data/agent.RyupiI/var/snort/log

The odd thing is that the
/usr/local/lib/snort_dynamicrule directory is
not created during the Snort installation. Fine if the directory must be
created manually, but where do I get the libdynamicexamplerule.so
file from?
