If your HDA server is headless, then WebVNC is not for you (because you will not have a desktop session running). Instead, install a VNC client on your remote computer and [[VNC|VNC Server]] on the HDA.  There is however a hack to allow you to run WebVNC from a headless server. This is rather complex, and will not allow you to boot with a monitor attached without changing files again.  You need to modify you xorg.conf to emulation a monitor.  cd /etc/X11/ nano xorg.conf save it as xorg.conf.bak nano xorg.conf replace everything with  Section "Monitor" Identifier "Monitor0" HorizSync 31-81 VertRefresh 56-75 EndSection  Section "Device" Identifier "Card0" Driver "vesa" EndSection  Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" EndSection  save and close xorg.conf  nano /boot/grub/grub.conf save it as xorg.conf.bak nano /boot/grub/grub.conf add above title Fedora GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" Reboot If you ever want to use a monitor, you just need to restore the .bak files.
