==Introduction==

In this article, you will see how to perform a network diagnostic and tools to check the status of the machine.

==Ping==

The '''ping''' is a command to test and verify the accessibility of a machine through the network.
It is necessary to launch this command ping followed by the IP or the desired domain as follows.

===Linux===

On '''Linux''', you will have to open the terminal and launch the following command by replacing the IP or the domain by the desired one:

'''ping 8.8.8.8'''

This will give us the following overview:

'''ping google.com'''

This will give us the following overview:

===Windows===

On '''Windows''', it will be necessary to open the Windows command terminal and launch the command.
Concerning the command prompt, it is possible to open it by doing :

- Type '''Win + R''', a window will open to execute the requested program, it will be necessary to indicate '''cmd.exe''' to obtain the terminal.
- It is also possible to search for '''Command prompt''' in the '''Start''' menu.

'''ping 8.8.8.8'''

This will give us the following overview:

'''ping google.com'''

This will give us the following overview:

===Mac OS===

On '''Mac OS''' you will need to use the '''Network Utility''' application and launch the Ping tool:

- Go to '''Finder''', and launch the search by clicking on the magnifying glass at the top right.

- Type Network Utility and open it.

It is also possible to find it by this path: '''/System/Library/CoreServices/Applications'''

Alternatively, for earlier versions of Mac OS it is possible to find the utility here: '''Finder > Applications > Utilities'''

- Go to the '''Ping''' option, and fill in the field with the domain to test or the IP address.

- Click on Ping.

This will give us the following overview:

==Traceroute==

A '''traceroute''', or '''tracert''', is a command to follow the route of an IP packet from your local machine to the desired machine or domain.

===Linux===

On '''Linux''', you will have to open the terminal and install the traceroute command if it is not already the case:

'''apt install traceroute'''

Once this is installed, you can run the following command by replacing the IP or domain with the desired one:

'''traceroute 8.8.8.8'''

===Windows===

On '''Windows''', it will be necessary to open the Windows command terminal and launch the '''tracert''' command as before.

'''tracert 8.8.8.8'''

This will give us the following overview:

===Mac OS===

On '''Mac OS''' you will still need to use the '''Network Utility''' application and run the '''Traceroute''' tool:

- Go to the '''Traceroute''' option, and fill in the field with the domain to test or the IP address.

- Click on Trace.

This will give us the following overview:

==Network configuration==

We are going to see different tools allowing us to have all the network information of the local machine.

===Linux===

On '''Linux''' it is possible to obtain this information with the command '''ip''' through the terminal:

'''ip addr show'''

This will give us the following overview:

[[File:Ipaddr.png]]

===Windows===

On '''Windows''', you will have to open the Windows command terminal and run the '''ipconfig''' command as before.

'''ipconfig'''

This will give us the following overview:

[[File:IpconfigW.png]]

===Mac OS===

On '''Mac OS''' it is possible to see this information directly through its interface.

To do this, choose the '''Apple Menu > System Preferences > Network'''.

For more information on managing your network on the Mac, here is a guide from Apple support : https://support.apple.com/guide/mac-help/change-network-settings-on-mac-mchlp1102/mac
