If deselected, the Raspberry Pi will need to be configured with a Standard VNC clients will not be able to connect to the Raspberry Pi. Deselecting it willĬause the RealVNC server to stop listening for VNC connections, and Says “Allow direct VNC connections over TCP”. Note: in the “Connections” section, do not deselect the checkbox that Program and RealVNC’s proprietary protocol. Improve the security when using RealVNC’s proprietary client Set, but only the first 8 characters are examined when using If prompted, create a VNC password to use. Press the “Apply” or “OK” button to make the changes. Needed if IPv6 is being used, but is not needed if only IPv4 is Optionally, press the “Add rule” button again and create a ruleįor connections from “::1” to “Accept the connection”. Select the default “Any other IPv4/IPv6 address” rule and press Press the “Add rule” button and create a rule for connections from Since directĬonnections with the unencrypted standard VNC protocol is insecure. Remote clients to connect directly to the VNC server. Select the “Connections” section and configure it to not allow Will prevent standard VNC clients from being used. Set to “Prefer on”-do not change it to “Always on”, because that Settings are also proprietary to RealVNC: it is safest to leave it Do not use Unix password or Interactive unixĪuthentication, which are proprietary to RealVNC. In the “Security” section, change the authentication to “VNC Right-click on the VNC server icon in the taskbar, and select.Menu icon (top right corner of the “VNC Server” window) and Clicking on the VNC server icon in the taskbar.The top right of the Raspberry Pi screen. When the VNC server is available, the VNC server icon should appear at Configure the VNC server to only allow connections from localhost If using the command line, run sudo raspi-config to do the same thing. Interfaces settings with SSH and VNC enabled. From the Raspberry Pi menu, choose Preferences >.If using the graphical user interface, use the Raspberry Pi Setup Enable remote access via SSH and VNC. This article describes how to use the standard VNC securely, by only RealVNC’s own client program-standard VNC clients do not support the It supportsĮncryption and longer passwords. RealVNC’s proprietary protocol should be secure. But it can be used with any VNC client program. It only supports a very weak password that is 8 characters or The Raspberry Pi comes with a RealVNC VNC server, which implementsīoth standard VNC as well as RealVNC own proprietary protocol. Security is very important: while there may or may not beĪnything valuable on your Raspberry Pi, it can be used by attackers asĪ foothold to attack more valuable targets. But it only takes a few simple steps to make it While it is functional-a remote VNC session can beĮstablished-it is at risk, especially when standard VNC is used over VNC is not secure: the common method of using VNC with the Raspberry
