I've been using fail2ban since version 8x to harden my server. Now after upgrading to version 10 my f2b has stopped working. My understanding is there has been some change in owncloud logging syntax in OC 10. Can someone tell me how to change my f2b configuration so it understands OC10?
Your failregex is not quite correct from what i can see and doesn't match the ones for 8.x and 9.x provided at . In oC 10.0 only the order of the entries changed ,  so it should be easy to apply those changes to the failregex listed at  and just re-order the failregex to match the new syntax / order.
