Every network administrator needs to know how to listen to port traffic on a server.
So you have a Linux server up and running, but you either suspect there might be some nefarious traffic coming in, or you just want to know what's going on at all times with this new machine.
With the tshark command you can listen to incoming traffic, so as to monitor your ports on a Linux server.
If you have multiple interfaces or you use this server for containers, you'll need to know which interface to have TShark listen to.
Figure C. Although there is much more to TShark, that is all you need to know to get you going on listening to port traffic on your Linux server.
