您要查找的是不是：
- The files and resources reside on the source host. 文件和资源存在于源主机中。
- The ICMP message is packaged in an IP datagram and routed to the source host. ICMP的信息也按照IP协议打包，寓于数据体中，并且路由至源主机。
- ICMP message to the source host, informing it that the packet delivery was not successful. 目的地不可到达消息,通知发送主机包传递不成功。
- A closed package copies all the files from the source host and places the content on a central distribution serve. 一个封闭包从源主机复制了所有文件并把内容放在一个中心发布服务器上。
- Flow control ensures that a source host does not overflow the buffers in a destination host. 流量控制确保来源主机不会让目的地主机有溢出缓冲现象。
- Nagios is an open source host, service and network monitoring program. Who uses it? Lots of people, including many big companies and organizations. Nagios是一个用来监控主机、服务和网络的开放源码软件,很多大的公司或组织都在使用它。
- At distribution time, the resources do not need to be collected from the source host; they are already contained in the software package block. 在发布时,资源无须从源主机获得;它们已经被包含在软件包块中了。
- If problems are encountered during routing, the Internet Control Message Protoccol or ICMP sends messages and reports errors to the source host. 如果在安排路径的过程中遇到问题，互联网控制信息协议（ICMP）就把信息和错误报告向源主机发送。
- End systems use port numbers to select the proper application. The source host dynamically assigns source port numbers. These numbers are always greater than 1023. 终端系统使用埠号来选择正确的应用。来源主机动态地指定来源埠号，这些数值总是大于1023。
- The source host is the system upon which the software package block is stored, and the location of the resources referenced in the software package and software package definition file. 源主机是存储软件包块的系统,也是软件包中引用资源的位置,以及软件包定义文件存储的地方。
- Multicast is a communication approach on one source node sending the same message to multiple destination nodes. IP multicast technology decreases link bandwidth overhead,network resource consumption and source host burden. 组播是一个源节点将同一信息传送到多个目的节点的通信方式,IP组播技术减少了网络不必要的带宽开销、网络资源的消耗以及大大减轻了源主机的负担。
- If the receiving hosts IP address matches the requested IP address, an ARP reply is formulated with the requested hardware address and sent directly to the source host. 如果接收方主机IP地址与要求的IP地址匹配，就生成一个包括发送方所要求的硬件地址的ARP回应帧，并直接发送给源主机。
- The news comes from a reliable source. 这消息来自可靠的来源。
- Since the current IP protocol permits source hosts to alter source addresses in IP packets, attackers are able to send out IP packets with empty or false source addresses. 由于当前的IP协议允许源主机改变IP包里面的源地址，攻击者能够发出一个空的或者伪造的源地址的IP包。
- Source host proceeds as Alice, and multiple hosts proceed as Bob. Each host contributes the part of encrypted circuit representing its function, and thus the resulting encrypted circuit is a cascade of sub-circuits. 以源主机充当Alice，多个主机充当Bob，所有主机贡献出加密电路当中代表自己函数的部分，各个子电路进行级联，从而构造出最终的加密电路。
- My wages are the principal source of my income. 薪金是我收入的主要来源。
- Solar energy is a new kind of source of energy. 太阳能是一种新型能源。
- The sun is the ultimate source of energy. 太阳是能量的最基本来源。
- A source of irritation or annoyance. 令人生气的事或者引起烦恼之事
- The groundwork or source of something. 基础，根源某事物的基础工作或根源
