I changed the snort.conf as follow

var WHITE_LIST_PATH /etc/snort/rules
var BLACK_LIST_PATH /etc/snort/rules


this is fine...


preprocessor reputation: \
memcap 500, \
priority whitelist, \
nested_ip inner, \
whitelist $WHITE_LIST_PATH/RPP_white.rules, \
blacklist $BLACK_LIST_PATH/RPP_black.rules


ok... this is fine now... what was it before?  It was this one whitelist $WHITE_LIST_PATH/white_list.rules, \

blacklist $BLACK_LIST_PATH/black_list.rules 



in the /etc/snort/rules I rename the files to RPP_black.rules & RPP_white.rules
but there was another file name blacklist.rules which is listed at the bottom of
the snort.conf file


ok... what does the following command return?

   ls -la /etc/snort/rules/*list*.rules -rwx------ 1 snort snort   1039 Jul 19 09:00 /etc/snort/rules/black_list.rules

-rw-r--r-- 1 snort snort 608573 May 22 15:45 /etc/snort/rules/blacklist.rules
-rwx------ 1 snort snort      0 Jun 17 13:09 /etc/snort/rules/white_list.rules
 



# site specific rules
include $RULE_PATH/local.rules
include $RULE_PATH/app-detect.rules
include $RULE_PATH/attack-responses.rules
include $RULE_PATH/backdoor.rules
include $RULE_PATH/bad-traffic.rules
include $RULE_PATH/blacklist.rules


what are the contents of this blacklist.rules file? i suspect it may be the one 
that should have renamed as RPP_black.rules...

can you see the confusion between black_list.rules and blacklist.rules now? 
which one is which? ;)

there should also be a whitelist.rules OR white_list.rules file for the 
reputation processor... its name should be in the same format as the proper 
black list one for the reputation processor...  in other words...

   white_list.rules
   black_list.rules
 it is white_list.rules

black_list.rules

OR

   whitelist.rules
   blacklist.rules

one of those is proper for the reputation processor... what is the name of your 
white list file? we will see that in the "ls -la" output from above ;)


I restarted the snort but still get the same error

yes, this shows the format of that file is not the IP or IP/CIDR format 
expected... that file is a standard textual GID:1 rules file... we renamed the 
wrong black_?list.rules file...


All those rules are located in /etc/snort/rules

Here is part of the RPP_black.rules, not sure if this is the correct format

[trim]

yeah, definitely the standard textual rules format... not what the reputation 
processor wants... what was the original name of this file?
