SSL tunneling is preferred method of connecting to VNC, but more on that in other article.VNC ( Virtual Network Computing ) Servers enables remote desktop access for Linux systems similar to MSTSC in windows. One thing that is important and worth mentioning – VNC is not secure by itself, and it is completely unencrypted. We will now try and connect to our VNC server via Windows client. We will open port 5901 firewall-cmd -permanent -add-port=5901/tcp Next, we will add VNC port exceptions to firewall. Next, lets check and verify that VNC server is listening netstat -tlnp Systemctl start enable status is up and running.
Now, with following commands we will reload VNC server, enable it to start at startup and check if it is up and running systemctl daemon-reload Sed -i 's/enforcing/disabled/g' /etc/selinux/config When you are done, type :wq! to save and quitīefore starting VNC we need to disable SELinux setenforce 0 Then run following command (file will be opened in vi editor) vi blank screen will open, and you need to enter following configuration into it (change informaticar with your username) ĮxecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'ĮxecStart=/usr/bin/vncserver -autokill %i We will create new configuration file /etc/system/system/ su Next, we will have to configure VNC server. Now let’s switch back to root account by running following command: exit Next we, will switch to user which will use VNC and set VNC server password: su – informaticar Installation command for TigerVNC is dnf install tigervnc-server tigervnc-server-module Let’s proceed with VNC Server installation When you are done with editing, quit vi with :q! Wayland should be set to false: WaylandEnable=false
Prerequisite for the VNC server is GUI interface – GNOME for CentOS 8/RHEL 8.īut, before we start installation procedure, we will check if Wayland display manager is configured as default display manager.įirst, we need to change to root by entering following command: su Another one of quick tutorials, this time on the topic of VNC server on CentOS/RHEL
