syslogd

運作方式

kernel

kernel產埋舉旋生的訊息交由klogd處理，klogd再交由syslogd處理。

套用程式

套用程式產生的訊息，可以在應趨己趨用程式的設定檔中，改變設定參數，以決定要將套用程式產生的訊息交由套燥汗全syslogd處理，或是由套用程式自行處熱驗組理。

運作方式設定

有二個設定檔

/etc/sysconfig/syslog

# Options to syslogd

# -m 0 disables 'MARK' messages.

# -r enables logging from remote machines

# -x disables DNS lookups on messages recieved with -r

# See syslogd(8) for more details

SYSLOGD_OPTIONS="-m 0"

# Options to klogd

# -2 prints all kernel oops messages twice; once for klogd to decode, and

# once for processing with 'ksymoops'

# -x disables all klogd processing of oops messages entirely

# See klogd(8) for more details

KLOGD_OPTIONS ="-x"

#

SYSLOG_UMASK=077

# set this to a umask value to use for all log files as in umask(1).

# By default, all permissions are removed for "group" and "other".

/etc/syslog.conf

# Log all kernel messages to the console.

# Logging much else clutters up the screen.

#kern.* /dev/console

# Log anything (except mail) of level info or higher.

# Don't log private authentication messages!

*.info;mail.none;authpriv.none;cron.none /var/log/messages

# The authpriv file has restricted access.
