entri mencegah jatuh ke seluruh rsyslog.conf
konfigurasi; jadi saya tidak akan melihat entri syslog router di /var/log/messages
.
Sentuh semua file syslog:
touch /var/log/net/chicago.log
touch /var/log/net/dallas.log
touch /var/log/net/firewall.log
Mulai ulang rsyslogd
dengan/etc/init.d/rsyslogd restart
Rotasi log
