ehtest

ehtest is a command-line utility used for performing network connectivity tests. It allows users to verify that a network path is functioning correctly and to diagnose potential issues. The tool sends packets to a specified destination and analyzes the responses to determine the health of the connection.

One of the primary functions of ehtest is to measure network latency, which is the time it takes for a packet to travel from the source to the destination and back. By measuring latency, users can identify bottlenecks or delays in the network. Additionally, ehtest can report on packet loss, indicating whether any packets were dropped during transmission. High packet loss can significantly degrade network performance.

ehtest typically supports various network protocols, such as TCP and UDP, allowing for testing different types of network services. Users can specify parameters like the target IP address or hostname, port number, and the number of test packets to send. The output of ehtest usually includes detailed statistics about the test, such as minimum, maximum, and average latency, as well as the percentage of packet loss.

This tool is valuable for network administrators, system engineers, and IT professionals for troubleshooting network problems, monitoring network performance, and ensuring the reliability of network services. It provides a quick and efficient way to gain insights into the state of a network connection.
