Description

\\192.168.2.250\Release\FEP\FEP_V3.0.4_Debian8
在192.168.2.236 moxa da682环境搭了一个复现环境
semodel.db配置104c采集192.168.2.80Dcdebug的3405端口
2401端口转发104s

测试复现过程:
1)192.168.2.190客户机用104c测试程序连接moxaFEP的2401端口
2)拔掉192.168.2.190的网线
3)另找一台客户机192.168.2.130,用104c测试程序连接moxaFEP的2401端口,socket能建立,但发送起始帧moxa不回答
等待1小时,客户机192.168.2.130,用104c测试程序连接moxaFEP的2401端口,socket能建立,但发送起始帧moxa还是不回答
ssh远程登录moxaFEP,netstat -ano 查看190ip机器的2401端口socket链路还是on在线状态

注意,测试复现时,被拔掉网线的104c客户机网线 保持断开,不要插上!!!

后续版本已修复
tcps端口服务侦听,本身在假活后,只要主动向死链路发送数据,15s后会自行断开。不发不断
