CSF stopped blocking temp nor perm
Posted: 17 Jun 2023, 20:48
Since latest Ubuntu update (23.04) I've noticed that CSF stopped working correctly. I didn't notice any temp nor perm IP ban. There is also no mail notification about that, but in logfile I see that there is many same connections which are refused after some time/connections. I'm really not sure WHERE is the problem, because before update all seems work well. There is no new changes in configuration (both server, services and csf), so I'm here with question - whats wrong? 
I've tried reinstallation csf, no success. Fresh config - no success... I've no idea what to do next.
Also LFD sends tons of mails that syslog check failed and logscanner error. I've do some research on forum and someone has told to disable syslog check - ok, but before april update that works.
