Hello All,
I've been running Fedore for years, and it used to be I could just
walk the menus and share my desktop. That doesn't seem to work any more.
I've googled until my fingers bled... I can get VNCServer up and running
but when I access it from another machine I get a desktop but it's a new
desktop. I want to access the existing desktop from another computer...
I know, it's dangerous, but my FW to the internet is a CentOS box with
SSH and to get to my desktop you need to ssh to my FW with proper
credentials, and forward a tunnel to my desktop and then log in there as
well, so I'm comfortable with the security.
So, how do I set it up to share the existing desktop?
You need to a) make sure you've installed the "tigervnc-server-module"
RPM (which provides the /usr/lib64/xorg/modules/extensions/libvnc.so
module); and b) add the "vnc" module to X.
To do the latter, I have a file:
/etc/X11/xorg.conf.d/00-system-setup-vnc.conf
that contains this content:
# This file was manually created by Rick Stevens
Section "Module"
Load "vnc"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Option "SecurityTypes" "VncAuth"
Option "UserPasswdVerifier" "VncAuth"
Option "passwordfile" "/path/to/your/vncpasswd/file"
EndSection
Obviously, replace "/path/to/your/vncpasswd/file" with the appropriate
stuff (the double quotes MUST be there) and you'll need to create
that password file and password using
vncpasswd /path/to/your/vncpasswd/file
Then reboot and you SHOULD be able to just "vncviewer remotehostname",
enter the password you used for the "vncpasswd" command and the main
main desktop should appear (assuming your firewall permits incoming
connections for that port, typically TCP port 5900).
You can also tunnel the remote VNC session via ssh:
vncviewer --via user@hostname hostname
You'd need to put in the ssh password first, then the VNC password.
I do this to access my desktop at home (my firewall only permits
incoming ssh sessions from my office IP or my internal home network).
Alternately, you can use something like TeamViewer. It's up to you.
