Good day, all,
	Thanks for a great ruleset!

	In:
alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS 80 (msg:"WEB-MISC Netscape
Enterprise directory listing attempt"; content:"INDEX " offset:0; depth:6;
flags:A+; reference:cve,CAN-2001-0250; reference:bugtraq,2285; classtype
:attempted-recon; sid:1048; rev:2;)

	there's a missing semicolon after "content:"INDEX "

	Also, in
snortrules/exploit.rules:alert tcp $EXTERNAL_NET any -> $HOME_NET 109
(msg:"EXPLOIT pop2 x86 linux overflow";flags: A+; content:"|eb2c 5b89 d980
c106 39d9 7c07 800 1|"; classtype:attempted-admin; sid:284; rev:1;)
	and
snortrules/exploit.rules:alert tcp $EXTERNAL_NET any -> $HOME_NET 110
(msg:"EXPLOIT pop3 x86 bsd overflow";flags: A+; content:"|5e0 e31c 0b03
b8d7 e0e8 9fa 89f9|"; classtype:attempted-admin; sid:286; rev:1;)

	The hex content uses mispaired hex digits such as 800 1 ; perhaps
80 01 would be more common usage?

	One final request, if I may.  sids 666 and 661 have quotes (' or
`) in the content field.  Would you consider putting the quote characters
in hex?  I have a particular tool that's trying to read the snort rules
and is having trouble with those.  :-(
	No big thing, just thought I'd ask.
	Cheers,
	- Bill

He tells me the two are unrelated. I do hope so.
