This blog post describes a proof-of-concept to implement distributed Fail2Ban banning by appending banned IPs to a centrally shared newbans.log (hosted over SSHFS) so cooperating Fail2Ban nodes can immediately apply the same bans; it includes server and node setup steps, fstab/SSHFS mounting, Fail2Ban action/filter/jail configuration, example logger commands, testing guidance, and caveats about backend polling, noise from multiport bans, scalability, and log rotation.
