Re: Why all the rules parsing errors?

Hunch:

You did the make and then you didn't do the make install
and the old snort is earlier in your path than ./snort....
(Not that I would ever make such a silly mistake, nope... 
 Just a hunch... ;-)

cheers,

It sounds like you are somehow still running the old version of snort. 
What version is it reporting when it starts up?

I just upgraded from snort 1.3 or something to 1.8p1. I then downloaded
the latest ruleset I saw posted (1.7). I had to edit snort.conf to get
lots of spaces out and finally got it working, but when it gets to the
rules include files I am getting errors that would indicate that most of
the rules are invalid.

The first error (line 4 in exploits) is "bad TCP flag = "+". The
relevant portion of the line reads: "...; flags: A+; content:..." The
problem is there are countless lines that use this same construction -
are they all wrong?

 I commented out the first 7 lines in exploits (passing by the first
bunch of A+ lines) and then got an error in line 8: "Unknown Keyword
"reference" in rule! Once again, the error is present in countless
lines. The relevant section of line 8 is: "...; reference:
arachnids,492;)"

Can anyone help me out here? If you hadn't already guessed I am not
familiar with the proper syntax.
