我已经设置了一个rsyslog服务器(基于CentOS 6),可以与一些远程主机一起使用.

但是,当我添加Cisco ASA防火墙时,它会记录其消息！

rsyslog.conf如下：

# rsyslog v5 configuration file

# For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html

# If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html

### MODULES ####

$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)

$ModLoad imklog # provides kernel logging support (previously done by rklogd)

# Provides UDP syslog reception

$ModLoad imudp

$UDPServerRun 514

#### GLOBAL DIRECTIVES ####

# Use default timestamp format

$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

# Include all config files in /etc/rsyslog.d/

$IncludeConfig /etc/rsyslog.d/*.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.

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

配置文件如下：

##RSYSLOG configuration file for Remote Logs

$FileCreateMode 0640

$template PerHostLog,"/var/log/remote/%HOSTNAME%.log"

if ($fromhost-ip startswith '10.1.5' or $fromhost-ip startswith '10.2.8') then -?PerHostLog

& ~

这些规则有什么问题吗？

TCPdump显示来自10.2.8.1主机的消息到达服务器,但syslog选择忽略它们.为什么？？
