Re: Dynamic Preprocessor does not alert and capture packet

[Big Whale <d0lph1n98 () yahoo com>]

The preprocessor can be loaded but in ModSecProcess() function, the preprocessor supposed to output the alert if the 
packet matched port 80. But it does not works, so i thought the problem could be the preprocessor rules. I already 
tried config autogenerate_preprocessor_decoder_rules in snort.conf and define the preprocessor alert generator id in 
the preprocessor_rules. Yet everything does not seems to work like it supposed to. I am building my preprocessor based 
on SSH preprocessor. Why don't you try compile and run it locally so you can experience what kind of problem it is.

  Hi Big Whale,
 
 Can you describe in detail what works and what not? Which decoder rule? Have you seen the rule get triggered in your 
preprocessor? Again, SSH preprocessor has example how to generate a preprocessor alert.
 
 Best,
 Hui.

 I already add "config autogenerate_preprocessor_decoder_rules" in my snort.conf file and put the plugin's alerts in 
the preprocessor.rules and gen-msg.map. But still no alert from my preprocessor. The preprocessor loaded correctly.
