UFW enable no logging UBUNTU / LINUX

vi /lib/ufw/ufw-init-functions


Coller ça:

 if [ ! -z "$LOGLEVEL" ]; then
            /usr/sbin/ufw logging $LOGLEVEL || true
        fi

juste avant ça dans la fonction ufw_start()

 if [ ! -z "$IPT_SYSCTL" ] && [ -s "$IPT_SYSCTL" ]; then
            sysctl -e -q -p $IPT_SYSCTL || true
        fi

        if [ "$error" = "yes" ]; then
            /bin/echo -e "$out"
            return 1
        fi


/etc/ufw# vi ufw.conf

# Please use the 'ufw' command to set the loglevel. Eg: 'ufw logging medium'.
# See 'man ufw' for details.
LOGLEVEL=off
