I was wondering if it was possible to have fail2ban clients on different machines and have a server on one machine communicating with all the clients?
Here's my situation: I have 4 servers and I'm using fail2ban to protect them. For now I have one client and one server installed per machine. I wonder if I could just have one client on each machine and have only one server total on one machine that would communicate with all clients. All the servers are running on CentOS and I'm using iptables to ban.
Do you have any idea on how to do that?
