Echo is a graphical network utility for checking the reachability of remote hosts. It provides a straightforward interface for performing ping tests without opening a terminal or entering command-line options.
The application uses GTK and Libadwaita, giving it an appearance consistent with modern GNOME applications. Users can enter a destination, start a connectivity test and examine the results through a compact interface.
Echo is intended for routine network checks rather than comprehensive monitoring. Its configuration controls allow users to adjust how frequently requests are sent, how long replies are awaited and how many probes are performed.
This is free and open source software.
Key Features
- Graphical interface for checking network host reachability.
- Send ping requests to specified network destinations.
- Support IPv4 and IPv6 testing.
- Configure the number of requests sent during a test.
- Adjust the interval between successive probes.
- Set the maximum time allowed for a response.
- Specify the source address used for supported tests.
- Display connectivity results without requiring a terminal.
- GTK and Libadwaita interface following GNOME conventions.
