When I add the code to my jail.local,

action   = iptables[name=nginx-custom, port=80, protocol=tcp]
               telegram

the IP is not stopped anymore. It is still in the iptable, but it I can still access the server from that ip. Any thoughts?

Hola, muchas gracias por tu aporte.

Al intentar hacer funcionar el script ejecutando solo /etc/fail2ban/scripts/send_telegram_notif.sh -b

Me da este error: -bash: syntax error near unexpected token `newline'

Sabes a que se debe?

Gracias

Hello! Your script works great for me at the first try. I found a very good tutorial from you in NextCloud Support Forum.

Now, I would like to pass to Telegram the name of the Jail that block the IP.

Looking at /etc/fail2ban/jail.conf I saw:

# The simplest action to take: ban only
action_ = %(banaction)s[name=%(__name__)s, port="%(port)s", protocol="%(protocol)s", chain="%($

And:

# "filter" defines the filter to use by the jail.
#  By default jails have names matching their filter name
#
filter = %(__name__)s[mode=%(mode)s]

So... is name=%(__name__)s, the way of obtain the jail name? If yes, could you help me edit your script to make possible send the jail name?

To show for example this message in Telegram:
The IP: 150.136.60.xxx has been banned by 'apache-badbots'
