无法连接Microsoft Azure Vm中的端口 [英] Could not connect Port in Microsoft Azure Vm
问题描述
我在Microsoft Azure中创建了Red Hat VM，并且能够通过ssh进行连接。
我已经在VM中启动了Java服务器端口8081并且启动成功。但是我无法在浏览器中查看它。它没有加载。
我尝试过以下操作，但都没有加载： -
主持人：80
主持人：8080
主持人：8081
我已在网络安全组和相关子网中添加了入站安全规则。我仍然无法在浏览器中查看我的服务器。
我已经按照
netstat -tuplen
（并非所有流程都可以识别，非自有流程信息
将不会显示，您必须是root才能看到它。）

根据您的截图，我注意到您的服务正在侦听tcp6。据我所知，如果端口只提供ipv6服务，则无法使用IPv4地址进行访问。
我注意到你使用jetty容器，jetty默认使用IPv6。您可以允许jetty force使用IPv4。有一个很好的答案。
I have created Red Hat VM in Microsoft Azure and able to connect via ssh.
I have started Java server in VM with port 8081 and it started successfully. But I am not able view it in browser. Its doesn't get loaded.
I have tried the following and but all doesn't get loaded:-
host:80
host:8080
host:8081
I have added Inbound security rule in Network security Group and associated subnet to it. Still I am not able view my server in browser.
I have followed this document for inbound security rule
Here is my inbound rule
netstat -tuplen
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

According to your screenshot, I notice that your service is listening on tcp6. Based on my knowledge, if the port only provides ipv6 service, you could not use IPv4 address to access.
I notice that you use jetty container, jetty use IPv6 by default. You could allow jetty force to use IPv4. There is a good answer about this.
