Looks good. I have installed, added a "jail" and path /var/log/auth.log I am unable to place a regex for it to detect the failure. Want something like "\Failed.+from.+\d" or such. No matter what I enter, it says "no regular expression is defined. No delimitor, quote, slash, etc. seems to work either. How does one enter these?
