我想转发（ rsyslog 8.4.2-1 ）所有系统日志消息到127.0.0.1端口。 为了做到这一点，我在/etc/rsyslog.d/expose-42000.conf添加了一个文件：
*.* @127.0.0.1:42000
重新启动rsyslog（日志中没有错误消息）后，我试图收听传入的消息：
netcat -u 127.0.0.1 42000
尽pipe在/var/log/syslog显示了消息，但仍然没有输出。
为了确保文件确实包含在内，我在debugging模式下运行了rsyslogd，并且看到include发生了：

有什么我失踪？
我认为一切都很好，但你的netcat使用。
我把你的configuration改为verbatim，运行syslogd -dn
但后来我跑这个：
nc -u -l -p 42000
并得到了预期的日志。 -l是为了听。 您的命令尝试连接到非打开/侦听UDP端口。
