Ah ok, I see.
Thank you for your help YM.
No problem! Can you verify at your end if you are seeing the same?

Betreff: RE: [Snort-users] Missing shared object files in snapshot download file

Which version/date of the rules are you running?
 
The reason I am asking is this:
 
The ruleset released until the 19 August contained the new the shared objected categories:
 

dev@box:/tmp# ls -l old/snortrules-snapshot-2962.tar.gz 
-rwxrwxrwx 1 dev dev 33080965 Aug 21 10:34 snortrules-snapshot-2962.tar.gz
 
dev@box:/tmp$ md5sum old/snortrules-snapshot-2962.tar.gz
2b84e9aee0f2eaf32e51a1375ec824f5
 
The ruleset released on the 21 August was stripped out of these new shared object rules:
 

dev@box:/tmp# ls -l new/snortrules-snapshot-2962.tar.gz 
-rwxrwxrwx 1 dev dev 25374704 Aug 21 10:34 snortrules-snapshot-2962.tar.gz
 
dev@box:/tmp$ md5sum new/snortrules-snapshot-2962.tar.gz 
9ddb9552995f5c637d11d690623bf414  snortrules-snapshot-2962.tar.gz
 
Note the size difference. This is also evident if you list (ls -l) the so_rules directory of both rulesets. The old 
one definitely contains the categories as specified by the blog post, the newer one does not. If your rules stubs are 
individually included in snort.conf rather than the all-one-file (snort.rules) as generated by PulledPork, then the 
above could be the reason.

Subject: [Snort-users] Missing shared object files in snapshot download file

I read about the reconstruction of shared object rules in the blog. So I'm confused about the missing file report. 
(see below)

....
Aug 23 19:22:40 c1 snort[801]: FATAL ERROR: /etc/snort//etc/snort/so_rules/browser-other.rules(0) Unable to open 
rules file "/etc/snort//etc/snort/so_rules/browser-other.rules": No such file or directo
Aug 23 19:22:40 c1 snort[796]: Starting snort: [FAILED]
Aug 23 19:22:40 c1 snort[805]: Stopping snort: [FAILED]
Aug 23 19:22:40 c1 systemd[1]: Started Snort IDS system.
...

The stub file couldn't be generated because the browser-other.so file isn't delivered in the latest snapshot 
download file.
There are more files missing not only browser-other.so. I expected all files listed in the blog to be included in 
the snapshot download file.

Is this a planned measurement of the reconstruction of shared object rules?

Greg
