Step 3: Start vncserver : vncserver
[tutorialspots@tutorialspots ~]$ vncserver You will require a password to access your desktops. Password: Verify: Would you like to enter a view-only password (y/n)? n A view-only password is not used New 'tutorialspots.net:1 (tutorialspots)' desktop is tutorialspots.net:1 Creating default startup script /home/tutorialspots/.vnc/xstartup Creating default config /home/tutorialspots/.vnc/config Starting applications specified in /home/tutorialspots/.vnc/xstartup Log file is /home/tutorialspots/.vnc/tutorialspots.net:1.log
III. Configuring VNC Server
Step 4. Edit file ~/.vnc/xstartup
#!/bin/sh unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS exec startxfce4
Step 5: Edit file ~/.vnc/config
# securitytypes=vncauth,tlsvnc # desktop=sandbox geometry=1920x1080 # localhost # alwaysshared dpi=96
Step 6:
cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service vi /etc/systemd/system/vncserver@:1.service
Content example:
[Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking User=tutorialspots Group=tutorialspots # Clean any existing files in /tmp/.X11-unix environment ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/usr/bin/vncserver %I PIDFile=/home/tutorialspots/.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' [Install] WantedBy=multi-user.target
Step 11:
su - systemctl stop vncserver@:1.service systemctl daemon-reload systemctl enable vncserver@:1.service systemctl start vncserver@:1.service
If error you can reboot your server.
Check status:
systemctl status vncserver@:1.service
IV. Connect to VNC server
Step 7(optinal – recommended): Set Up SSH Tunneling for more security
ssh -L 5901:127.0.0.1:5901 -N -f -l tutorialspots ipserver
Example for Windows (Cygwin):
D:\cygwin64\bin>ssh -L 5901:127.0.0.1:5901 -N -f -l tutorialspots 198.204.228.20 tutorialspots@198.204.228.20's password:
Step 8: Connecting using Real Vncviewer
