Hello and welcome to our demonstration video on logging into Linux machines
on the screen. You can see a local machine with a gooey or graphical login.
And we'll demonstrate the graphical login for a local machine.
Then it will demonstrate a remote graphical login from windows using RDP.
And finally, we'll demonstrate a remote text mode login with SSH.
So let's jump in.
Now, I'm here with the
Ubuntu machine that has a graphical desktop installed.
And again, this is a local machine, meaning it's physically sitting here with me.
We have the usernames available on this machine.
You might only have one username, but we'll select the one that we're going to use
and then enter your password.
Nothing too unusual about this.
We have a full desktop environment so we can use the graphical interface.
Now note that even though there is a desktop interface,
we have a terminal emulator also to work from the command-line.
And when we're done with this session,
we just log out.
Now let's connect to the desktop of a remote machine with windows.
Now let's say you're on a windows desktop machine and you
want to view the desktop of a remote Linux machine.
Our
Ubuntu machine has X RDP installed and it's configured
so that Windows machines can connect to the desktop
in windows, search for remote desktop,
the client will open up and then you put in the IP of the remote machine. In
this case, it's 10.0 0.0 0.81.
And you may see a certificate warning here. Click. Yes.
And now we have a login screen for a remote Linux machine,
enter your username and password.
And now we have our Ubuntu desktop waiting for us.
You can just maximize the screen and it's just like being on the desktop,
but from your Windows computer
and this is great for connecting to a desktop on a remote machine.
Now, typically Linux servers don't have a desktop and you must connect with
SSH. As we discussed in the last video.
This is super easy in Windows Mac or Linux just open up a terminal
type in SSH,
then the username,
the at sign and the IP address or domain name of the remote server.
If it's the first time you've ever connected to the machine,
you will see this prompt type in.
Yes,
then enter your password and you're in.
And now you can see I'm here at the terminal of my remote
Ubuntu machine using
SSH.
This concludes our demo for logging into Linux machines.
Next, we're going to take a look at built in system documentation
