나는 이것을 가지고있다 /etc/rsyslog.d/my_iptables.conf:

:msg,contains,"[netfilter] " /var/log/iptables.log

이 /etc/rsyslog.conf:

저는 Debian 8(jessie) 및 iptables v1.4.21을 사용하고 있습니다.

내 질문은: 왜 iptables가 로그를 생성하지 않습니까?

도와주셔서 감사합니다!

답변1

rsyslog처음에는 사용자 정의 로그 파일이 생성되지 않는 것을 발견하여 직접 만들었습니다.
참고: 권한은 그 어느 때보다 중요합니다! - rsyslog에 새 로그 파일에 쓸 수 있는 권한이 있는지 확인하고 다음과 같이 시도하십시오.

print_status "Give Iptables its own log file - instead of /var/log/syslog"


sudo touch /var/log/iptables.log
 # assign appropriate ownership to your setup
sudo chown -v root:adm /var/log/iptables.log
sudo chmod -v 660 /var/log/iptables.log

rsyslog그런 다음 변경 사항을 적용하려면 재부팅해야 합니다.

sudo service rsyslog restart

아니면 배포판에서 사용하는 명령이 가능합니까?

sudo /etc/init.d/rsyslog restart
