ping: check the network before you blame the app

Before you blame the app, check the network.

ping -c 4 google.com

What it does

ping sends small test packets and shows whether a host answers and how long it takes. -c 4 stops after four packets.

It's the first step in troubleshooting: if ping works by IP address but not by name, the problem is DNS.

Ping a site, then ping its IP address. Did both work? Share what you found in the community.
