How do I configure fail2ban for webmin-auth? on Ubuntu Server 18.04

[techcomputerworld]

Hello, I have configured fail2ban in Ubuntu Server 18.04 in the jail.local file, I have copied it to jail.local as I said in a tutorial and you configure everything about that file.
I put these lines in this configuration and it still does not work after logically restarting



[webmin-auth]
enable = true # Indicamos que el jail está habilitado
port = 10000 # Puerto que vamos a bloquear
filter = webmin:auth # Nombre del filtro que vamos a aplicar
logpath = /var/log/auth.log # Log donde se registran los intentos de acceso en webmin, podría variar según la distribución de linux
maxretry = 2 # Número de intentos para banear IP

this configuration is to protect the webmin I want to install it in a VPS

If you want to protect webmin, don't allow any remote access at all. Force it only to be available to 127.0.0.1 users, then only allow ssh remote access using key-based authentication, never passwords. Then you would use ssh as a SOCKS proxy from your browser to tunnel into the server, effectively accessing the system from localhost.

But really, if you care about security, don't use webmin at all.
