 This video is part of series be sure to check out the link in the description of this video for the full playlist today We're gonna be starting to look at some networking stuff Gonna keep it very basic gonna get just the basic information about our network settings or network devices on our computer and Best way to do that or quickest way to do that is if config if config will give you a quick list of all your network Devices and although they may be named different things depending on your setup some of the most commons are Etho or eth will be wired connections and Wlan will be wireless connections and then Lo will be your loop back connections Which I'll talk about in a minute and then the number is the number So if you have two wired connections or at least two ethernet cards in your computer You will have them numbered eth o eth one eth two depending on how many you have right now on my desktop I have a wired connection and my loop back connection And again wireless connections are usually Wlan either zero or one or two depending on the number of devices You have in which one it is Occasionally you'll see eth for wireless connections now a loop back connection Just for your reference is basically kind of like a virtual network device that allows you to do networking stuff without Leaving your computer and it will look at some examples of this later on where maybe you want to have Networking services running on your computer, but you don't want them accessible to anybody outside From other devices you just want to be able to connect back to your machine using these services without Opening up any security issues that there might be while you're testing stuff That's what the loop back connection does it basically it's a fake network device and usually when you type in local hosts or One two seven dot zero dot zero dot one you're actually connecting back through your your your your your connection here So you can use that in a in a browser to connect to your web server on your current machine and make that web server Or other services not accessible to remote access So that's just a quick look at if config it actually does other things You can actually use it to turn on and turn off network connections So you'll have to be either suit or a route to do this, but you can say if Config the name of the device so etho and I could type in down and hit enter And that will shut down that network device and to bring it back up I will run the same command but with up so from the shell I'm gonna do that because I don't want to disconnect from the internet right now But from the shell if you want to be able to disable a network connection you can use that command And that's this a quick overview. Oh, and I guess it should also mention it shows your IP addresses here different IP addresses So if you're looking for your IP address that would be a quick way to find it So when I thank you for watching as always, I hope that you enjoyed this video Thank you for watching.
