Bloco UFW constante no Syslog

Question

Bloco UFW constante no Syslog

#1 resposta do (0 votos)

0

Ao rever meu syslog, descobri que 99% dele consiste em instruções UFW BLOCK de 3 ou 4 IP's (veja abaixo; editado para espaço). Isso é normal? O que essas entradas significam? Se eles são seguros, como posso corrigir ou impedir que eles sejam gravados no log? Ao pesquisar essa questão, parece que isso está de alguma forma relacionado ao multicasting, sobre o qual eu não sei nada. Eu já tentei adicionar acesso de entrada / saída para 224.0.0.0/24 para UDP e, em seguida, reiniciar o UFW sem sucesso.

Configurações do UFW

Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip

Estas são as mensagens de log do UFW geradas pelo Kernel.

No seu sistema, um arquivo de configuração diferente é feito para gerenciar esses registros,

 luvpreet@DHARI-Inspiron-3542:~$ cd /etc/rsyslog.d/
 luvpreet@DHARI-Inspiron-3542:/etc/rsyslog.d$ ls | grep ufw
 20-ufw.conf

Veja o conteúdo deste arquivo,

luvpreet@DHARI-Inspiron-3542:/etc/rsyslog.d$ cat 20-ufw.conf 

# Log kernel generated UFW log messages to file
:msg,contains,"[UFW " /var/log/ufw.log

# Uncomment the following to stop logging anything that matches the last rule.
# Doing this will stop logging kernel generated UFW log messages to the file
# normally containing kern.* messages (eg, /var/log/kern.log)
#& stop

Renomeie este arquivo e remova o arquivo .conf no final,

luvpreet@DHARI-Inspiron-3542:/etc/rsyslog.d$ sudo mv 20-ufw.conf 20-ufw

Agora, reinicie o rsyslog,

luvpreet@DHARI-Inspiron-3542:/etc/rsyslog.d$ sudo service rsyslog restart

Isso interromperá o registro dessas mensagens.

NOTA - Se você não vir este arquivo, procure por esta linha :msg,contains,"[UFW " /var/log/ufw.log em todos os arquivos na pasta /etc/rsyslog.d . Onde você vê, comente esta linha e reinicie o rsyslog.
