[问题3] 在Linux系统中,inetd服务的默认配置文件为______。

在Linux系统中,默认情况下,xinetd所管理服务的配置文件存放在______。

A./etc/xinetd/

B./etc/xinetd.d/

C./usr/etc/xinetd/

D./usr/etc/xinetd.d/

答案

参考答案:B

解析:

[分析]: inetd后台进程在/etc/inetd.conf配置,那个文件中包含了关于每一个超级后台进程需要提供的服务的条目。与inetd相比,xinetd能够启动基于RPC(远程过程调用)的服务,并支持访问控制。xinetd可以限制进入连接的速度、来自特定主机的进入连接的数目,或者某个服务的总连接数。通过用于每个从属后台进程的独立配置文件来配置xinetd。这些文件位于/etc/xinetd.d/目录中。

In some parts of China, school children have to cook for themselves. But now, with the help of donations, this becomes a history forever.

At the donation ceremony in southwest China's Lishan Primary School in Yunnan province, kids gathered at playground to receive something new to them -- a kitchen system. Gu Dongjun was the donor of the new system. She wanted the children to grow up healthily.” I hope the kids can eat clean and hot food,” she said.

Lishan Primary School has more than 500students. Half of them live at school, and have to cook for themselves in the open air. They have been picturing their dream kitchen since they knew they would no longer have to cook outside.
