Snort: drop, not block

Hi!
How can i setup only to drop packet or. block ip for 0.1s or. max 5s?
-
Install cron package and reduce the time of snort expitetable and cron execute frequency
-
Any options to change this in snort config file?

*/5 means run each 5 minutes.
The -t 3600 command arg means remove ip only when it reaches 3600 seconds.
So you may need to change */1 to * and -t 3600 to -t 50
