linux – Snort Message – WARNING: No preprocessors configured for policy 0
This message indicates that no snort preprocessor is loaded. In order to get rid of this warning, please use the following command:
snort -v -c /etc/snort/snort.conf
Please make sure that the configuration file /etc/snort/snort.conf is present and preprocessors are enabled in the configuration file.
I had the same error:
No preprocessors configured for policy 0
That was because I forgot to unpack all the rules into the proper folders. After unpacking the rules, the error went away.
linux – Snort Message – WARNING: No preprocessors configured for policy 0
Check if it is enabled and see if it has any sid or msg with:
snort -A console -c /etc/snort/snort.conf
And check if any of the preprocessors are sending alerts if not you should recompile it.
