Fail2Ban is not blocking users after unsuccessful attempts

Hello,

I've been trying to configure Fail2ban on my development server and I envy those people who say "Fail2ban" is so easy to configure

The thing is SSH login attempts are recorded on /var/log/auth.log but with my testing username I can type passwords endlessly that user will never blocked.

This is my config for SSH

Any help would much much appreciated

Code:

ignoreip = 127.0.0.1/8


bantime  = 600

findtime = 600
maxretry = 3

backend = auto

usedns = warn
protocol = tcp

chain = INPUT
action_ = %(banaction)s[name=%(__name__)s, port="%(port)s", protocol="%(protocol)s", chain="%(chain)s"]


action = %(action_)s

[ssh]

enabled  = true
port     = ssh
filter   = sshd
logpath  = /var/log/auth.log
maxretry = 3

logpath = /var/log/sshd.log
maxretry = 3

 

Which Distro you are using, if in case you are using Debian/ubuntu use this guide

 

Thanks!!! That guide is really good. Not sure what the solution was in case anyone else has this problem but it was either

1. backend = polling
2. I forgot to restart!!!!
