To Dr. Stephen,


I corrected my pulledpork.pl and try to run this script again including
restart snort again. There is no invalid configuration again.

Thank you so much!

Subject: Re: [Snort-users] 93.184.215.200 black listed IP address
We have it listed as an “Attacker” from an outside source.  It’s a private
IP out registered through RIPE’s server.  Allegedly registered to a private
address in Santa Monica, CA.
Don’t think that’s Microsoft.

Hello,

Good day.

Any idea on why the 93.184.215.200 IP address was included on the
black_list.rules? It seems to be a false positive.
Am seeing microsoft.com domains on tcpdump.

regards,
Ceejay

Don't confuse blacklist.rules (one of the VRT rules files) with the
blacklist of IP addresses referenced in your reputation preprocessor. It
looks like you may have edited blacklist.rules instead of the
black_list.rules file referenced by default by the preprocessor in
snort.conf. Bear in mind that black_list.rules does not exist when you
install Snort - your have to create it (and the white_list.rules file too
if you are using a whitelist). I tell my students to choose a different
name for the blacklist file (the one with the IP addresses) to try to avoid
exactly this confusion.

Hello,

Before I have a problem, I installed pulledpork for getting the latest
rule from snort.

After that I restart snort but get this error:

but in the blacklist.rules, there are just ip address per line only


<trim digest>

Looks like you aren’t loading the blacklist as a blacklist inside the
preprocessor.  It appears Snort is trying to load the Blacklist as a
configuration option or something.

Can you attach your snort.conf?
