Network Debugging Assistant is a network debugging mobile client tool specially designed for network engineers. Supports TCP and UDP protocols for communication between hosts, and supports hexadecimal sending. Interface introduction, simple operation, wide range of uses! Software tutorial: 1. The user needs to prepare two devices. Device 1 clicks on the TCP server and sets the port, clicks to enter and waits for the connection. Device 2 clicks on the TCP client, enters the IP and port of the TCP server to be tested, and clicks to enter. When both devices show that the connection is successful, the server and client can send data to each other. 2. UDP connection does not need to establish a server. Just configure the IP addresses and port numbers of the peers with each other. Remarks: Please note that the two devices must be in the same LAN during the test.
