网络里的FRP配置的应用端口，阶段性的断联

swordsman

FRP服务的端口都是通的，frpc客户端可以联通，但是配置的应用的frp端口，随机的阶段性断开，无法通信，过一段时间又恢复通信，好像自从VX有了这个服务以来，一直是这样，稳定性很差。下面只是随便找了一段时间的日志。用telnet命令在不同的网络机器上测试，故障出现时，确实是telnet应用端口不通，排除自身客户端网络的问题，确定就是VX frp服务端的问题。

swordsman 请尝使用日本区域的 FRP 服务，看看是否也会出现此问题。

swordsman

更换成日本区域的FRP服务后，和FRP服务端断连的频率变低了，但仍然存在断连不可用的情况。不知道是网络的原因还是FRP这个软件本身就存在bug的原因。

swordsman 是否有可能是宿主机网络不稳定？目前我们也有应用该服务，暂时没有发现问题。

swordsman

微林也有可能是宿主机网络不稳定，所以想多种方式监控下看看，如果用网络监测功能监测服务端口一直OK，那说明可能就是frp客户端我这边网络的问题，如果网络监测显示FRP服务端口不稳定，那就说明可能是服务端有问题，用网络监测功能测试化就排除了我客户端网络的问题，方便对比。

swordsman

我准备用微林提供的基于TCP端口网络监测功能，定时监控下frps-jp.vxtrans.com 对应的frp服务端口15001的状态，看看是不是这个服务端口不稳定从而导致服务断连

微林

swordsman 这个方案可能不太行，如果frpc没有连接到frps并启动对应的监听，那么frps上对应的端口不会监听。这会导致网络监测服务也无法连接到frps配置的端口。

swordsman

微林收到，我在用别的网络客户端配置测试一下，谢谢指导。
