초보가 로그에 관해 질문드려요

리눅스초보입니다. ^_^

시스템 로그가 전혀 남지않는데 왜 그런지 좀 알려주세요ㅠㅠ
경로가 틀린것도 아니고...

/etc/syslog.conf 파일내용은
=====================================
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none                /var/log/messages

# The authpriv file has restricted access.
authpriv.*                                              /var/log/secure

# Log all the mail messages in one place.
mail.*                                                  /var/log/maillog

# Log cron stuff
cron.*                                                  /var/log/cron

# Everybody gets emergency messages
*.emerg                                                 *

# Save news errors of level crit and higher in a special file.
uucp,news.crit                                          /var/log/spooler

# Save boot messages also to boot.log
local7.*                                                /var/log/boot.log
======================================

ps 로 확인해보니
======================================
root      8585     1  0 Oct06 ?        00:00:00 syslogd -m 0
root     25123 25073  0 11:49 pts/0    00:00:00 grep syslog
======================================
제대로 실행되고 있는거 아닌지요...

지금 /var/log/maillog, messages, secure 파일사이즈가 0 이에요...
======================================
-rw-------  1 root      root     0 Oct  2 04:02 maillog
-rw-------  1 root      root     0 Oct  4 18:05 messages
-rw-------  1 root      root     0 Oct  4 18:05 secure
-rw-------  1 root      root     0 Oct  2 04:02 spooler
