odd. I didn't actually see snort throw an error. I use a script to
import the sigs into a db. My script crapped out on that syntax. Since
that had never happend before, and I've never seen that syntax I
thought it was a syntax error.

Wally,

This syntax is allowed. Was snort complaining about the rule? If so,
what was the error and what version are you running?

Thanks,

Just updated my community set and the following rule has a syntax error...

alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS
(msg:"COMMUNITY WEB-PHP Horde index.php show XSS attempt";

Should be....

alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS
(msg:"COMMUNITY WEB-PHP Horde index.php show XSS attempt";
flow:established,to_server; uricontent:"/services/help/index.php";
nocase; uricontent:"show="; nocase; uricontent:"URL=javascript";
nocase; reference:bugtraq,18845; classtype:web-application-attack;
sid:100000703; rev:1;)

changed the three nocase:; to nocase;
