如果将/etc/services中的514那行注释,也能重现这个问题。看来问题就在这里了。
至于原因,可以man sysklogd。
The strategy is to have syslogd listen on a unix domain socket for locally generated log mes-
sages. This behavior will allow syslogd to inter-operate with the syslog found in the standard
C library. At the same time syslogd listens on the standard syslog port for messages forwarded
from other hosts. To have this work correctly the services(5) files (typically found in /etc)
must have the following entry:
syslog 514/udp
If this entry is missing syslogd neither can receive remote messages nor send them, because the
UDP port cant be opened. Instead syslogd will die immediately, blowing out an error message.
不过/etc/services文件是setup包安装的,该文件无法访问或者被修改,sosreport所收集的rpm -Va居然没有校验出来?!真是有够纠结! |
