내 서버로 CentOS를 사용하여 rsyslog 설정이 작동하고 있으며 Kali를 클라이언트로 사용하고 있습니다.
Kali에서 로거를 사용하여 테스트 로그 메시지를 보내고 CentOS 메시지 파일과 내가 설정한 시설별 파일에 로그 메시지가 나타나는지 확인할 수 있습니다 /var/log. 커널 메시지를 제외한 모든 것.
messagesCentOS의 파일 kernel.log에 커널 메시지가 표시되지만 /var/log.
이를 통해 Kali 클라이언트가 로그 메시지를 올바르게 전송하지만(메시지 파일에 수신되어 표시됨) rsyslog.confCentOS의 파일에서 뭔가가 누락되었다고 추론합니다.
다음은 Kali에서 로그 메시지를 생성하는 데 사용하는 것입니다.
logger -t "new test" -p kern.err "testing kernel log messages"
CentOS에서 작업을 수행 tail -f messages하면 로그 메시지가 나타납니다. 그러나 cat파일을 열면 kernel.log비어 있습니다.
rsyslog.conf이것이 CentOS 시스템에 대한 것입니다 . 어떤 조언이라도 환영합니다.
전체 rsyslog.conf 파일은 다음과 같습니다.
# rsyslog configuration file

#### MODULES ####
# The imjournal module bellow is now used as a message source instead of imuxsock.
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imjournal # provides access to the systemd journal
$ModLoad imklog # reads kernel messages (the same are read from journald)
$ModLoad immark # provides --MARK-- message capability
# Provides UDP syslog reception
#$ModLoad imudp
#$UDPServerRun 514
# Provides TCP syslog reception
$ModLoad imtcp
$InputTCPServerRun 514
#### GLOBAL DIRECTIVES ####
# Where to place auxiliary files
$WorkDirectory /var/lib/rsyslog
# Use default timestamp format
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
# File syncing capability is disabled by default. This feature is usually not required,
# not useful and an extreme performance hit
#$ActionFileEnableSync on
# Include all config files in /etc/rsyslog.d/
$IncludeConfig /etc/rsyslog.d/*.conf
# Turn off message reception via local log socket;
# local messages are retrieved through imjournal now.

# ### begin forwarding rule ###
# The statement between the begin ... end define a SINGLE forwarding
# rule. They belong together, do NOT split them. If you create multiple
# forwarding rules, duplicate the whole block!
# Remote Logging (we use TCP for reliable delivery)
#
# An on-disk queue is created for this action. If the remote host is
# down, messages are spooled to disk and sent when it is up again.
#$ActionQueueFileName fwdRule1 # unique name prefix for spool files
#$ActionQueueMaxDiskSpace 1g # 1gb space limit (use as much as possible)
#$ActionQueueSaveOnShutdown on # save messages to disk on shutdown
#$ActionQueueType LinkedList # run asynchronously
#$ActionResumeRetryCount -1 # infinite retries if host is down
# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
