So I've setup my old laptop with Fedora v28 workstation.

What can I use to, (for want of the correct Linux terminology), RDP into my Fedora laptop when I'm out in the field?

Not being command line savvy, it will need to be a GUI interface.

Thanks.

If you want RDP, install xrdp, start the service and enable it to run at boot.

sudo dnf -y install xrdp
sudo systemctl start xrdp
sudo systemctl enable xrdp
sudo firewall-cmd --permanent --add-port=3389/tcp
sudo firewall-cmd --reload

Will install it, start the service, enable the service at boot time, and open the local firewall port for it.

Went ahead and did all the above and it seems to work, but I don't log in.

I get prompted for my username & password, but this comes up:

I installed TigerVNC the other week and only partially configured that, I wonder if that might be screwing up XRDP?

How can I uninstall TigerVNC?

I found that root can log in OK, but not my standard user account, which makes sense to me.

OK, So XRDP needs my stadard account to be in a group called 'tsusers' as shown below:

I don't think there is a tsusers group, so I need to create that and add my account to the group.
How do I do that?

Well I've got most of the bugs sorted out and things seem to be working.

dnf remove tigervnc-server

Thought I would give this ago also... this is what I ran into

This is from Windows to Fedora.

To add a user to a specific group

useradd -G {group-name} username should work. You likely will need to run under sudo to do this though.

I like to use sudo gpasswd -a username groupname personally. but it all gets the job done.

Yep, that is what I was getting also. Can you log in with root?

I was getting that error & the one I posted above. I rebooted several times for various reasons and things started to become a bit more reliable.

Thanks everyone for the help.

Here's what I have done since.

Added my <USER> to the wheel usergroup and rebooted. Since, I seem to be able to sign in. but yes,.. I was able to sign in as <ROOT>

If you don't add a -a it removes all secondary groups other than the one you define. You pretty much always want to do usermod -aG group user

I guess using sudo gpasswd -a username groupname avoids remembering to add -aG?

Yeah. I've always done usermod but it's personal preference.

However the only way I know of to remove a user from a group is gpasswd

It occurred to me just now, that you should not need a full reboot after adding the <user> to your group... All that should be needed is a log out/in

@scottalanmiller or @JaredBusch - please correct me if I have that incorrect.

Log out and log in is all that is required to apply new group permissions.

Yes - I learn. here is the same command - but in just three lines:

sudo dnf install xrdp -y
sudo systemctl start xrdp | sudo systemctl enable xrdp
sudo firewall-cmd --permanent --add-port=3389/tcp | sudo firewall-cmd --reload

You can make anything a one line command if you want. Back when running IRIX if hit their 512 character limit and have to script a single command when compiling open source tools on that. Thankfully haven't run into that issue recently!

You can shorten the second. If you do

system to enable --now xrdp

It will enable and start the service at the same time.

Also why are you using a pipe?

That's a good point. For your continuing BASH shell learning @gjacobse, a pipe ~ | ~ passes the output of the first command to the one after it. So ls -lha | grep ".." lists all files including the hidden ones and then searches for any with .. in the string returned. When you just want to run commands one after the other, the proper concatenation been is &&

What does ; means after a command?

&& will stop if the preceding command throws an error while a semicolon will run the following command no matter if the first one throws an error.
