Re: [Snort 2.2.0] Rules won't trigger

All,Just to clarify this, I'm seeing different login data than what the rule looks for in PCAPs from both Edin and my own testing. This may be caused by a variety of reasons, from a difference in the client we're using vs. what was used to create the rule, an update to the protocol, etc. This does not necessarily mean that the current rule is always invalid, just that there are some false negatives.
For all those who may be concerned about this rule, I've created a bug internally, and the rule will be updated and/or a new rule will be added as appropriate in the next rule pack after we determine what the appropriate course of action is.

Hi, thanks a lot for your contribution. Alex was able to pinpoint the error down to the incorrect signature. Anyway, I have another rules not triggering too, for example test-cgi and printenv. These signatures seem correct but also do not trigger. I am still looking for errors in my config... :-\ Would someone be so kind to test this with his/her Snort setup? Best regards, Edin Joshua Berry schrieb am 20.01.2005 17:28:If you are not queing the packets then snort will alert on the first signature that matches (if I remember correctly), therefore only one of these signatures will be logged. You need to use: config event_queue: max_queue x log y order_events priority Where x is replaced with a number you feel comfortable with queing, and y is the number of signatures to alert on in order of priority (I think)....
