 Welcome back everyone today. We're going to talk about setting up additional network profiles in Linux So I'm in the network properties right now. This is the network properties menu in Linux Mint Cinnamon Edition Other types of other versions of Linux have their own network manager, but they all basically look the same You should whenever you open up your network manager Now you should see this add profile button and this is Usually a settings menu To be able to adjust the settings of that particular network adapter. So here. I have a Wi-Fi adapter that's off I have a wired connection And if we go into settings So I'm clicking the the little Configuration button go into settings if we go to IP version 4 because I have an IP version 4 network You can see that the main address IP version 4 is enabled and the main address is Being acquired through DHCP. So it this system From the wired connection Automatically receives an IP address from some DHCP server in this case the gateway And then we also have DNS that's configured. So it's on and I have two servers set These are the servers for open DNS, which is a public DNS service And then routes we don't have any routes set or anything like that Okay, so what I'm gonna show you today is basically how to set up a profile It's very easy to do and we are going to just switch the DNS servers Okay, so imagine that if I select one profile, I will use open DNS if I select another profile Then I will use I think we're gonna use Google's DNS servers. Okay, so My default profile my default profile already has the open DNS servers Selected so that's okay so then Next click on add profile and then we have a couple different options if you need to set up security for your network if you want to set up an identity so I'll say Google Google DNS Okay, Mac address if we need to spoof a magnet clone a Mac address and then go to IP version 4 And this is really what we want to change. So on some Sometimes I don't use automatic DHCP. So I want to actually manually set an IP address So instead of choosing DHCP, I can select manual and then I can actually put the IP address here And whenever I switch to this profile, then it will use the manually set IP address. Okay I use it on some of our internal networks that have restrictions based on Mac address and things like that to be able to switch between different networks very easily or for example, if you use One statically set IP address at your work one statically set IP address at home Then this is a really handy feature to have if you want to actually pre-program both of them into your system for now, I'm just going to leave this on Automatic or DHCP and while we're here. I'll just throw in a quick Recommendation I guess setting Your network connector to shared to other computers and Linux Mint This automatically configures one of your ports to be able to share The network but also the internet connection with other computers Connected to that port. So I usually have for example a Raspberry Pi and I use a crossover cable to in this case my laptop and then I share The wired connection on my laptop with the Raspberry Pi Basically runs a DHCP server on my laptop the Raspberry Pi gets an IP address and then it can use the internet Through my laptop. It's very very convenient. So I really use this shared with other computers feature a lot So we might set up a profile for that, but right now. I'm just going to set up Automatic DHCP just like before so I'm still going to receive the computer is still going to receive a IP address from the DHCP server in this case the gateway and I want to change the DNS servers Okay, so we are going to use Google's DNS servers So I'm going to add 8.8.8.8 which is one of the first ones and then 8.8. what was it 4.4? 4.4 Okay, so these are two of the Google's public DNS servers and I'm not going to set any routes here Okay, I'm not going to touch IPv6 But we could also configure an IPv6 network and have different profiles for those networks as well Which would also be handy in some situations click add And then here we have Google DNS and then wired connection 1. I could go in and rename this to open DNS but Just for the sake of this. I'm not going to Change the name. So if we want to select the profile We can just select it and now we've actually switched to the Google DNS profile. So I have here the same Address, okay, let's see Network just disconnected. So now it's connecting back Okay, so I get the same IP address because the router sees the same MAC address and Everything basically gets reconfigured automatically, but it's now using different DNS addresses so I'm just showing you DNS which is only moderately useful But you can completely change all of the network settings and keep them in these profiles and the profiles are very handy For lots of different situations like I said, especially if you're working with a lot of different Systems through your device. So I just thought I'd say that that's it for today. Thank you very much If you like this video, please subscribe for more
