从IP端口读取数据

Question

I am having an static IP (amazon ec2 instance) and a defined port which is connected to a device. This device send data on this particular port usually every minute over the GSM network.

For eg.172.20.1.170 is the IP and 4001 is port.

I am using C# socket to read the data but it is giving error "No connection could be made because the target machine actively refused it 172.20.1.170:4001"

Please suggest the sample code to read the data from the IP and port

Answer 1

尝试从网络浏览器（chrome、firefox）点击嵌入在你设备中的 ip 和端口。 . 你也可以试试超级终端..
