本文通过对Qnet 网络通信协议的分析，利用该协议可以将基于QNX Neutrino 的消息传递机制透明地扩展至整个网络的特点，采用了伪终端技术,on 命令等方法，解决了操作监控系统中如何启动远程进程以及如何查看远程节点的日志文件等关键问题。给用户提供了一个友好、高效的操作监控平台。关键词：Qnet；EAST；极向场；远程进程；伪终端Abstract: By analyzing the Qnet network protocol, we take advantage of this protocol’scharacteristic that extends the message-passing mechanism transparently over a network, and use ome techniques such as Pseudo-Terminal technique and on command etc to solve the keyquestion of the operation monitoring system such as how to start remote processes, how toexamine the log files on the remote nodes, offering users a friendly and simple operation andmonitoring platform.Keyworks: Qnet; EAST; Poloidal field; remote process; Pseudo-Terminal;
