If you want a great, but heavyweight GNOME interface, enter the following:
CENTOS TIGERVNC SERVER INSTALL
Otherwise, you need to install one of them: the TigerVNC server will start a parallel instance of this desktop environment for each login session, which means that we must have at least one GUI. If you already have GNOME, KDE, or other installed desktop environments, you can skip this step. Installing the graphical user interface (GUI) It will not be superfluous to mention that you can also restrict this port to certain groups, IP addresses, network cards, or other simple or complex firewall rules. # firewall-cmd -add-port = 5901 / tcp -permanent The command to open this port on Firewalld: In our scenario, we did only 1, so you only need to open the first dedicated VNC port: TCP 5901, as we already said. How many ports to open will depend on how many VNC server instances you need. Therefore, if you have a firewall installed, you must create an appropriate rule that allows VNC clients to connect. Since our VNC service is listening on TCP port 5901, you must be sure that such a port is open and accessible to external clients. If you see this, then everything is set up correctly. Installing TigerVNCĪnother test that you can perform before trying to connect to the server is to look at the active network sockets using the sscommand: if everything works correctly, you should see that the VNC server is working and uses TCP port 5901.
That's why we choose TigerVNC, which runs parallel sessions of the desktop environment of the computer (GNOME, KDE, or another GUI): this means that a virtual desktop will be created for each connection - this is exactly what we want. The latter, perhaps more powerful and secure, especially if you need to manage the server computer because each session will be a unique environment, configured with the permissions and rights of the connected user.
CENTOS TIGERVNC SERVER SOFTWARE
The software was developed by the Olivetti & Oracle research lab in Cambridge, UK, and its source code is still up to date and available under the General Public License (GNU).ĭepending on the server software, the VNC client will connect to the active desktop (for example, as TeamViewer or AnyDesk programs) or a standalone virtual desktop (like the Windows RDP remote desktop protocol). VNC (Virtual Network Computing) is a client-server protocol that allows a client computer (running a VNC client) to connect and control a remote computer (running on a VNC server). In particular, we will do this using the TigerVNC Server software, a free tool that allows using a stand-alone virtual desktop.Ĭloud Servers from €4 / mo Intel Xeon Gold 6254 3.1 GHz CPU, SLA 99,9%, 100 Mbps channel Try Introduction
CENTOS TIGERVNC SERVER HOW TO
In this guide, we will look at how to install and configure a VNC server on the CentOS 7.x operating system to allow remote connections from any VNC clients, such as TightVNC, RealVNC, and others.
