→Linux network connection configuration troubleshooting
# '''Can you ping 8.8.8.8?''' If all of the above work - check that your default gateway is set correctly with '''ip route''' and that you can ping the default gateway.
# '''Can you resolve google.ca?''' Run '''host google.ca'''. If it doesn't come back with an IP address, and all of the above worked - check that your DNS server is configured correctly and that you can ping it.
There is a number of other problems that could prevent your network connection from functioning but the above are the most common ones. You should be able to go through the troubleshooting process pretty quickly. Setting up the network in this course is never a primary task, but it's almost always a prerequisite for anything else we're going to do. You can't have a working web server (or any other kind of server) if you don't have a working network connection.
