Music can be a powerful tool to help improve sleep quality. Many studies have shown that listening to soft and relaxing music before bed can help reduce stress and anxiety, allowing the body to relax and prepare for sleep.

Sleep music can help induce a state of relaxation, lower blood pressure, and decrease heart rate. This can help calm the mind and prepare the body for deeper and more restorative sleep.

Additionally, music can help mask external noises that may disturb sleep, such as traffic or neighborhood noises. This can help maintain a quieter and more peaceful sleep environment.

In summary, sleep music can offer a range of mental and physical health benefits, helping to improve sleep quality. Try incorporating soft and relaxing music into your bedtime routine and feel the difference in your sleep and overall well-being.

Pode estar relacionado ao fato de desabilitar o rastreamento de conexão para tráfego NTP. Isso aparentemente faz com que as mensagens ICMP relacionadas a esse tráfego sejam sinalizadas como estado de rastreamento de conexão "inválido" na configuração padrão, a queda "inválida" aconteceu antes do ICMP permitindo.

Verificar e editar o ficheiro /etc/ufw/before.rules e /etc/ufw/before6.rules.
Se estiver conforme o primeiro exemplo, devemos editar conforme o segundo exemplo.


# drop INVALID packets (logs these in loglevel medium and higher)
-A ufw-before-input -m conntrack --ctstate INVALID -j ufw-logging-deny
-A ufw-before-input -m conntrack --ctstate INVALID -j DROP

# ok icmp codes for INPUT
-A ufw-before-input -p icmp --icmp-type destination-unreachable -j ACCEPT
-A ufw-before-input -p icmp --icmp-type time-exceeded -j ACCEPT
-A ufw-before-input -p icmp --icmp-type parameter-problem -j ACCEPT
-A ufw-before-input -p icmp --icmp-type echo-request -j ACCEPT

Edite o before.rules e o before6.rules para trocar esses dois blocos para que os ICMPs sejam permitidos antes que a verificação de "inválido" aconteça.


# ok icmp codes for INPUT
-A ufw-before-input -p icmp --icmp-type destination-unreachable -j ACCEPT
-A ufw-before-input -p icmp --icmp-type time-exceeded -j ACCEPT
-A ufw-before-input -p icmp --icmp-type parameter-problem -j ACCEPT
-A ufw-before-input -p icmp --icmp-type echo-request -j ACCEPT

# drop INVALID packets (logs these in loglevel medium and higher)
# moved to after ICMP to prevent NTP stuff from being blocked
-A ufw-before-input -m conntrack --ctstate INVALID -j ufw-logging-deny
-A ufw-before-input -m conntrack --ctstate INVALID -j DROP
