I have installed and web application which is running on port 8080 on centOS. I only have command line access (through putty) to that machine. I have tried to access that application from my windows machine from which I am connected through putty, but it is giving connection time out error.
我已经安装了web应用程序，它在centOS的8080端口上运行。我只有命令行访问权限(通过putty)到那台机器。我试图从我的windows机器*问这个应用程序，我是通过putty连接的，但是它会产生连接超时错误。
Then I have tried to open port 8080. I have added following entry into the iptables.
然后我试着打开8080端口。我在iptables中添加了以下条目。
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
一个输入-m状态-状态新-m tcp -p tcp -dport 8080 -j接受。
After adding this into the iptables I have restarted it with - /etc/init.d/iptables restart
在将其添加到iptables之后，我使用- /etc/ initon重新启动了它。d / iptables重启
But still I am not able to access that application from my windows machine.
但我仍然无法从windows机器*问该应用程序。
Am I doing any mistake or missing something?
我做错什么了吗?

First, you should disable selinux, edit file /etc/sysconfig/selinux so it looks like this:
首先，您应该禁用selinux，编辑文件/etc/sysconfig/selinux，使其看起来如下:
SELINUX=disabled
SELINUXTYPE=targeted
Save file and restart system.
保存文件并重新启动系统。
Then you can add the new rule to iptables:
然后可以将新规则添加到iptables:
iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT
and restart iptables with /etc/init.d/iptables restart
并使用/etc/ initter重新启动iptables。d / iptables重启
If it doesn't work you should check other network settings.
如果它不工作，你应该检查其他网络设置。
