내 로컬 /var/log/syslog 파일을 제어하려고 합니다. 현재 구조는 원격 파일을 /var/log/juniper/syslog/%fromhost-ip%/syslog.log에 기록하는 것입니다. 아래는 내 구성입니다.

로컬 호스트가 원래 위치(/var/log/syslog)에 기록하고 원격 클라이언트는 해당 위치(/var/log/juniper/syslog/%fromhost-ip%/)에만 기록하도록 이러한 결과를 필터링하려면 어떻게 해야 합니까? syslog.log)?
답변1
$IncludeConfig /etc/rsyslog.d/*.conf이 문제를 해결하기 위해 2개의 IP 기반 필터 조건을 주석 처리 하고 추가했습니다.
if $fromhost-ip == '127.0.0.1' then /var/log/syslog
if $fromhost-ip != '127.0.0.1' then ?JUNIPER
기본적으로 이는 localhost에서 들어오는 모든 것을 /var/log/syslog로 보냅니다. 그러면 원격 호스트 로그가 해당 동적 디렉터리로 전송됩니다.
