Comments 3 Posted In Red Hat Enterprise Linux RHEL 8.3 Vncserver and Vncviewer Latest response 2021-06-02T19:51:40+00:00 Installed new laptop with RHEL 8.3 we would like to use vncserver on the laptop in order for our customers to see demo's. No matter how I configure it, it isn't working. Please help with steps to get vncserver to work on RHEL 8.3.

I just switched to rdp. $ sudo dnf install xrdp then start / enable. for client side i use microsoft remote desktop on my macbook, and remmina on my ubuntu laptop MG Newbie 10 points 1 February 2021 11:17 PM Mario Gamboa Open the GNOME Display Manager (GDM) configuration file using your favorite command line editor. vi /etc/gdm/custom.conf Then uncomment this line to force the login screen to use Xorg. WaylandEnable=false Install VNC dnf install tigervnc-server tigervnc-server-module Next, switch to the user you want to run and use the VNC program by setting the user’s VNC server password (which should be at least six characters) su - vncuser $ vncpasswd In this step, you have to configure the TigerVNC server to start a display for the above user on the system. Start by creating a configuration file named /etc/systemd/system/vncserver@.service as follows. vi /etc/systemd/system/vncserver@.service Add the following configuration in it (remember to replace tecmint with your actual username). [Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking WorkingDirectory=/home/vncuser User=vncuser Group=vncuser PIDFile=/tmp/%H%i.pid ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/usr/bin/vncserver -autokill %i ExecStop=/usr/bin/vncserver -kill %i [Install] WantedBy=multi-user.target Save the file and close it. Before we move any further, let’s briefly understand how the VNC server listens to requests. By default, VNC uses TCP port 5900+N, where N is the display number. If the display number is 1, then the VNC server will run on display port number 5901. This is the port you have to use while connecting to the server, from the client. Normally selinux can cause issues to make simple just disable selinux setenforce 0 sed -i 's/enforcing/disabled/g' /etc/selinux/config Now reload the systemd manager configuration to apply the recent changes and then start the VNC service, enable it to auto-start at system boot time and check if it is up and running using the following systemctl commands, rembeber the number specify is the display could be 1 or 0 or 2 depending of the display you are using systemctl daemon-reload systemctl start vncserver@:1 systemctl status vncserver@:1 systemctl enable vncserver@:1 Next, open the port 5901 in my case because i'm using display 1 in your case you need to looking with port is using firewall-cmd --permanent --add-port=5901/tcp firewall-cmd --reload Now you are able to connect to the server via vnc Just in case you want to do locally and no put remote the connection Create a ssh-key ssh-keygen Copy the ssh-key to the server with vnc ssh-copy-id vncuser@server Now make a tunnel between you local machine and the remote server ssh -i ~/.ssh/id_rsa -L 5901:127.0.0.1:5901 -N -f -l vncuser 192.168.56.110 This one create a ssh tunnel Install the client in you local machine dnf install tigervnc-viewer Connect to the server using vncviewer localhost:5901 or vncviewer 127.0.0.1:5901 MK Community Member 32 points 2 June 2021 7:51 PM Masahiko Kohso New instruction posted on Apr. 26, 2021, for how-to setup tigervnc server in RHEL 8.3. https://access.redhat.com/solutions/5544351 It works.
