Changes in the latest rule packs

I know at least one person has noticed, but for those of you who haven't, we made a small change in the latest rule pack download on snort.org. My apologies for not sending out an advanced warning notice, but since most people use snort.org to view the documents, the change is seamless for the majority. So what did we (or I should say, I) do? We removed the rule docs from the rule tar balls and made them available separately. There is only one rule doc tar ball for registered and subscribed users. You can download them from the rule download page on snort.org at https://www.snort.org/snort-rules/ or you can use the command line to download. The links for the command line download are: Subscribed Users: http://www.snort.org/sub-rules/opensource.gz/<oinkcode> Registered Users: http://www.snort.org/reg-rules/opensource.gz/<oinkcode> Additionally, since there is no difference in the two tar balls, registered users can also use the subscriber link above and still get the docs. The two links are provided above for those folks who like to see consistency in their scripts :D Of course, you can still view the rule documentation on snort.org as normal from: http://www.snort.org/search/sid/<GID>-<SID> Note: for GID 1 rules, the GID is not necessary but the search will work with the <GID> being 1. As we move forward, we are thinking of changing the layout in the rule doc tar ball so that the directory limit for listing files using ls does not hamper those who need to do that. Right now, there are somewhere around 17 thousand individual documents all housed in one directory called signatures/. Quite a long time ago, we changed our storage for rule documentation and our layout in cvs for the rule documents follows the following format: Dir: Contains: 0/ docs from 100 through 999 1/ docs from 1000 through 1999 2/ docs from 2000 through 2999 3/ docs from 3000 through 3999 4/ docs from 4000 through 4999 5/ docs from 5000 through 5999 6/ docs from 6000 through 6999 7/ docs from 7000 through 7999 8/ docs from 8000 through 8999 9/ docs from 9000 through 9999 10/ docs from 10000 through 10999 11/ docs from 11000 through 11999 12/ docs from 12000 through 12999 13/ docs from 13000 through 12999 14/ docs from 14000 through 14999 15/ docs from 15000 through 15999 16/ docs from 16000 through 16999 17/ docs from 17000 through 17999 18/ docs from 18000 through 18999 so_rules/ so_rule docs pre-processors/ pre-processor docs deleted/ rule documents for those rules that have been deleted. Obviously, this has an affect for those users using the rule docs locally, scripts, uric etc would need to be modified, but in the long run it might make life a little easier. Bear in mind, whatever you use to view rule documentation from a local source would have to be smart enough to know that if a rule SID is in the 100 to 9999 range, the directory name is only one digit, if the rule GID is 3 then it is in the so_rules directory and starts with 3- and if the GID is something higher then it is in the pre-processors directory and starts with the GID. You could of course, un-tar the contents into the old signatures/ directory if you don't care about listing the contents of the directory and don't want to change anything. Personally, I manage the rule documentation using Perl scripts and a sid-msg.map (I have a special one that contains all rules and has the GID in there) and it works well. If anyone has any objections, ideas or would like us to do this sooner rather than later, please let us know. If anyone wants my special sid-msg.map generation script, I will be happy to put it up somewhere for you to download and use.
