![]() ![]() Because TightVNC is built into all Macs, it's a great tool for connecting to Macs. Hey, check this out! Look man, I'm on Ubuntu Linux! How cool is that? So what I want to do now, that's so much fun, let's do it again. Now, VNC has a password built into it which I've got ready to go. And all you have to do is type in the IP address or the fully-qualified domain name. But I just want to run the viewer which allows me to connect to people who are sharing their stuff. So when you install TightVNC, you get all this server stuff. Now, TightVNC is both a server and a client. All right, so I've installed TightVNC on here. So let's fire up TightVNC, and let's go see some other computers that are out there. So in order to take advantage of this, I had to get a program that runs on top of the VNC protocol called TightVNC which is completely free, and I've got it installed on here. In fact, VNC is built into pretty much all Linux and Mac machines. It's probably the most popular third-party protocol out there. If you want to start using other types of remote desktops, getting to Linux boxes, getting to Mac systems, we use a different protocol called VNC. So, RDP is great, but it's really more of a Windows thing than anything else. 'I was here.' Absolute proof that Remote Desktop Protocol worked exactly as we wanted it to. Now, I can come over here, and there he was. I'm just going to close this which will log me off of that other system. And what I'm going to do now is I'm just going to log out. 'I was here.' So, I've got that folder made. You can't really see anything, so what I'm going to do is go over to the C drive. However, I could do whatever I want to do here, and I am actually connected to that other system. You can't see what I'm doing on here 'cause I'm logged in as a different user. And now, I'm actually connected to this other computer. I know it looks like a login screen, but it's blank. Then, you'll see it's giving me a warning, so the one on the right goes blank. If I go ahead and hit yes, it's going to disconnect that other person. It cannot confirm that this is exactly the machine I want to connect to. It's already there because I tested this before we tried it, and I'm going to hit connect. And I just need to type in the name of the computer I want to connect to. So now, coming over to this other system, I'm just going to type in 'remote,' so there's remote desktop connection right there. Now I need to know my IP address or computer name, so I'm just going to run command, type ipconfig. I'm going to allow remote connections and just hit OK. Nobody wants to walk all the way to the server room, so let's go ahead and connect to this system using RDP. For example, if I got a bunch of Windows server systems sitting in a rack far away, RDP is the way we go to configure those servers. Once you're connected, nobody else can connect to it. With remote desktop, what we're doing in that case, is we're simply making a connection to another computer. With remote assistance, if somebody connects into my computer, it's as though we've got two mice and two keyboards. One says, 'Allow remote assistance,' and the other one is 'Remote desktop.' The differences between these two is subtle but important. So first of all, here I am in my system properties, and I've got two choices here. RDP's been around for a while, and it works fine with just about every version of Windows. So I've got a Windows 7 and a Windows 10 system. I've got one of them I'm going to set up to allow people to use RDP, and then we'll go connect to it with the other one. ![]() So, what I'm going to do is, I've got two computers up on the screen right now. RDP runs on port 3389, and it's pretty much unique to Windows. Now, in the Windows world, we use what's called, Remote Desktop Protocol. ![]() We have to deal with graphic resolutions differences, so there's a few ways to do this. So, there's a lot more to this than simply connecting to a command line interface. Today's operating systems are often using graphical user interfaces, and if I want to connect to another system, it's often more interesting to me to be able to actually connect to a desktop on another system. Now, connecting to a command line interface is cool, but if you really want to be great, why don't we connect to a remote desktop? Let's face it. ![]()
