How to Connect with VNC to a Linux Computer Across the Network
- Ubuntu Remote Desktop: Easy, Built-In, VNC Compatible. It discusses how to connect to Ubuntu desktop via VNC and RDP. 2020
Remote desktop connection from Ubuntu to Ubuntu (vino)
- Ubuntu Gnome Desktop (youtube) It works when I tested it on Ubuntu 18.04.
sudo apt install vino # Go to GNOME settings -> sharing -> enable remote desktop. # Type a password (not username is needed for remote desktop). sudo ufw allow from any to any port 5900 proto tcp sudo apt install dconf-editor dconf-editor # go to org -> gnome -> desktop -> remote access -> require encryption -> turn it off
In Remmina, type a new name. In the 'Protocol' drop-down list, select Remmina VNC plugin. Enter the server IP and enter the User password (again, no Username is needed). Hit "Connect". Done! Or use IP:5900 in order to quickly connect (use nmap localhost to check the exact VNC port).
- How to Remote Access to Ubuntu 16.04 from Windows. The instruction is the same for older versions of Ubuntu.
- On a Ubuntu server. Go to Dash, type 'desktop sharing' and select it. Check sharing. Close the dialog. Open a terminal and run ps -ef | grep vino to make sure the server is running.
- Disable encryption. Run sudo apt install dconf-editor. Go to Dash and type 'dconf' and select 'dconf editor'. When it opens, navigate to org -> gnome -> desktop -> remote-access, and uncheck the value of 'require-encryption.' Another way is to run gsettings set org.gnome.Vino require-encryption false.
- On a client machine (eg another Ubuntu), open a remote desktop client program (eg Remmina). Choose VNC as the protocol. Enter necessary information to connect to the server.

Tightvnc server
Remote desktop connection from Windows 7: xrdp
xtightvncserver may not play well in Unity.
Install xrdp on Ubuntu. That's it. See
- http://www.ubuntututorials.com/remote-desktop-ubuntu-12-04-windows-7/ Ubuntu 12.04
- http://www.tweaking4all.com/software/linux-software/use-xrdp-remote-access-ubuntu-14-04/ Ubuntu 14.04
- https://community.hpcloud.com/article/using-windows-rdp-access-your-ubuntu-instance
- http://www.ubuntugeek.com/xrdp-remote-desktop-protocol-rdp-server.html
sudo apt-get install xrdp sudo /etc/init.d/xrdp start
On Windows 7, open its Remote Desktop client utility mstsc.exe.
Instruction from Rock Pi 4.
Remote desktop connection to Windows 7 from xubuntu: rdesktop
sudo apt-get update sudo apt-get install rdesktop rdesktop xxx.xxx.x.x -f -u USERNAME -p PASSWORD rdesktop 192.168.1.4 -g 1280x720 -u USERNAME -p PASSWORD
where -f option means full screen and -g means geometry.
AnyDesk (cross platform)
Install AnyDesk on Ubuntu Linux. Not open source. Free for personal use.
RealVNC
The default vnc server included in Ubuntu is not quite compatible with other clients. For example I can connect to Ubuntu 14.04 from Ubuntu 16.04 but not from a Mac. The 3rd party software is better. See the following screenshot after I have installed RealVNC server.
Note that RealVNC Server is not free for commercial users but is free for home users up to 5 computers & 3 users; see https://manage.realvnc.com/. An email and a password can be used to sign in your account for activating the license in VNC Server.
To start VNC server, use (https://www.realvnc.com/docs/debian-install-remove.html)
sudo /etc/init.d/vncserver-x11-serviced start
The RealVNC will have an icon sitting on the tray at the top-right corner.
Before using VNC viewer, we also need to create a VNC password in VNC Server.
On Mac, the viewer can be launched from Applications -> VNC Viewer (if we have drag and drop the app to the Applications folder).
On Chrome OS, there is an VNC Viewer for Google Chrome to use. The IP address is special. For example, 192.168.5.127:80 for port 5980. See https://www.realvnc.com/docs/faq/connect-fail.html. Unfortunately I cannot connect successfully:(
Still not working on my iOS (2019-09-26).
Teamviewer
- Teamviewer. It works fine. After launching it, the software automatically creates an ID and password. We can change the password so it is fixed. Then launch the software on the client. Use the partner's ID and password to connect to it.
Guacamole
Install and Use Guacamole Remote Desktop on Ubuntu 20.04
NoMachine and Amazon cloud
It seems nomachine is using port 4000.
odroid@odroid:~$ sudo nmap -sV localhost Starting Nmap 7.01 ( https://nmap.org ) at 2016-11-16 20:10 EST Nmap scan report for localhost (127.0.0.1) Host is up (0.000051s latency).

NoMachine. I ran the service on my Ubuntu 12.04 server. I also tested the client on my Android 6.0 tablet and Odroid xu4 running Ubuntu 15.10. I am using the version 5.0.63. I need to use my server's user account info to connect.
odroid@odroid:~/Downloads$ ps -ef | grep nx nx 12168 1 1 21:11 ? 00:00:20 /usr/NX/bin/nxserver.bin root 12151 --daemon odroid 12199 12168 1 21:11 ? 00:00:12 /usr/NX/bin/nxnode.bin nx 12225 12168 0 21:11 ? 00:00:00 /usr/NX/bin/nxd odroid 12263 12199 1 21:11 ? 00:00:13 /usr/NX/bin/nxclient.bin --monitor --pid 1153 nx 15916 12225 24 21:28 ? 00:00:08 /usr/NX/bin/nxserver.bin -c /etc/NX/nxserver --login -H 5 odroid 15944 15916 33 21:29 ? 00:00:04 /usr/NX/bin/nxnode.bin -H 5 odroid 16130 8527 0 21:29 pts/1 00:00:00 grep --color=auto nx odroid@odroid:~/Downloads$ ls /usr/NX/bin drivers nxd nxkb nxplayer nxsh nxusbd nxagent nxesd nxkeygen nxplayer.bin nxspool nxauth nxexec nxlocate nxpost nxssh nxclient nxfs nxlpd nxprint nxssh-add nxclient.bin nxfsm nxnode nxserver nxssh-agent nxcodec.bin nxfsserver nxnode.bin nxserver.bin nxtunctl
If for some reason some nx programs disappeared, restart the service by
sudo /usr/NX/bin/nxserver --restart
It is interesting that nomachine is faster than 'ssh -X' method when I tested running a Qt application launched from Qt Creator. For example, the progress bar is not moving when it is supposed to move forward and backward when the app is launched through 'ssh -X'.

Remote desktop connection through vmware workstation
We shall be able to remote desktop connect to a Windows guest machine if the guest machine has configured to use bridge connection and a static IP. If there is a problem, it is likely caused by Window's firewall. See the two screenshots. We can just turn off the firewall of home network but keep the firewall on for the public network.
We don't need to use port forward for the remote desktop connection.

Remote desktop connection to NCI (outdated)
Note the information here is outdated now.
The version 1.7.1 of rdesktop program in Ubuntu 14 has a bug with mouse cursor (invisible). To fix the bug, download the version 1.8.3 and build it. See http://ubuntuforums.org/showthread.php?t=2266743
sudo apt-get update sudo apt-get install build-essential libx11-dev libssl-dev libgssglue-dev libpcsclite-dev tar zxvf rdesktop-1.8.3.tar.gz cd rdesktop-1.8.3 ./configure make sudo make install
After that the new rdesktop is located under /usr/local/bin folder. The old rdesktop installed through apt-get is not deleted.
