How To Show Failed Pings in Ubuntu

Ubuntu 19

In the world of network troubleshooting, the ping command is a fundamental tool. However, when using Ubuntu, the default ping utility does not provide an explicit feature to show failed pings. This article will guide you through several methods to monitor and display failed pings in Ubuntu.

Quick Answer

To show failed pings in Ubuntu, you can use the -O option in the ping command to receive a notification when a packet is not received before the next one is sent. Alternatively, you can enable the flood ping mode using the -f option, which prints a period for every sent ping and a backspace for every received reply. If you require more control and customization, you can modify the source code of the ping utility. However, this requires technical knowledge and may not be suitable for everyone.

Using the -O Option

In some versions of the ping utility, there is an -O option available. This option is designed to print a notification when a packet is not received before the next one is sent. Here’s how to use it:

ping -O 8.8.8.8

In this command, -O is the option that triggers the notification for missed packets. 8.8.8.8 is the IP address we are pinging, which in this case is Google’s DNS server. If a packet is not received before the next one is sent, you will see a message indicating this.

Using the -f Option

Another method involves the use of the -f option, which enables the flood ping mode. In this mode, a period is printed for every sent ping, and a backspace is printed for every received reply. This allows you to quickly see how many packets are being dropped. However, this option does not provide detailed information about the failed pings. Here’s how to use it:

ping -i 1 -f 8.8.8.8

In this command, -i 1 sets the interval between each ping to 1 second, and -f enables the flood ping mode. Again, 8.8.8.8 is the IP address we are pinging.

Modifying the Ping Source Code

If you need more control and customization, you can download the source code for the ping utility, modify it to include suitable printf calls, and build your own version of the utility. This allows you to add specific messages or indicators for failed pings. However, this approach requires more technical knowledge and may not be suitable for everyone.

You can download the source code for the ping utility from the iputils GitHub repository. After downloading and modifying the source code, you can build the utility using the make command.

Conclusion

While the default ping utility in Ubuntu does not provide the same level of functionality as the Windows ping utility, there are workarounds available. Whether you’re using the -O or -f options, or modifying the source code, you can effectively monitor and display failed pings. However, if having a clear indication of failed pings is crucial for your network debugging, you may need to explore alternative tools or scripts that offer more advanced features.

Remember, understanding the nuances of your network’s performance is key to maintaining a healthy and efficient system. Happy troubleshooting!

Can I use the `-O` option with all versions of the `ping` utility in Ubuntu?

No, the availability of the -O option may vary depending on the version of the ping utility you are using. It is recommended to check the man page or the documentation specific to your version of Ubuntu to confirm if the -O option is available.

How can I stop the flood ping mode enabled by the `-f` option?

To stop the flood ping mode, you can press Ctrl + C on your keyboard. This will send an interrupt signal to the ping process and terminate it.

Is modifying the `ping` source code the only way to show failed pings with specific messages or indicators?

Modifying the ping source code is one way to achieve more customization, but it is not the only option. There may be alternative tools or scripts available that offer more advanced features for monitoring and displaying failed pings. It is worth exploring different options based on your specific requirements.

Can I use the `-O` and `-f` options together?

No, the -O and -f options cannot be used together. They serve different purposes and are not compatible with each other. You need to choose one option based on your specific needs.

Are there graphical user interface (GUI) tools available for monitoring and displaying failed pings in Ubuntu?

Yes, there are GUI tools available for network monitoring in Ubuntu that can display failed pings. Examples include tools like Wireshark, PingPlotter, or Gping. These tools provide a more visual and user-friendly interface for monitoring network performance and displaying failed pings.
