hello, Payload: "uid=48(apache) gid=48(web)" (You must set this to the corresponding group your webserver is running to) If it finds the pattern 'uid=' it will continue searching until it finds '(web)'. If it find both, then the event is fired. The rule options are checked as a large logical and, and they are checked sequentially. Regards, Alejandro Flores
Hi, I am new to the snort. Can some one tell me when multiple contents are specified in a rule as in the following rule, what does it mean? Does it mean that all the contents MUST be matched and does it also mean that they should be in the same sequence as specified in the rule or the sequencing does not matter (for e.g for the following rule, "uid=" and "(web)" should they be in the same sequence or "(web)" can be before "uid=". alert tcp $HTTP_SERVERS $HTTP_PORTS -> $EXTERNAL_NET any (msg:"ATTACK RESPONSES id check returned web"; flow:from_server,established; content:"uid="; content:"(web)"; classtype:bad-unknown; sid:1884; rev:2;) Thanks GM _________________________________________________________________ Apply now for a Citibank Suvidha Account. http://go.msnserver.com/IN/45532.asp Get a FREE Citibank Picture Card . ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
