Why Is Fail2Ban & DenyHosts Not Working?
I installed and configured Fail2Ban first to get some form of protection on the SSH port I am using. Unfortunately, testing shows that it is simply not working. Can someone give me some hints as to what is going on? I have used a non-standard SSH port. Do I need to make Fail2Ban and DenyHosts aware of this?
What is the MINIMAL configuration I need to do so I can test to see if this application is actually blocking failed logins? It's simply not blocking failed logins. I could try logging in all day, still no banning going on. I am using Centos 6.5.
