In computing, Virtual Network Computing (VNC) is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer.It transmits the keyboard and mouse events from one computer to another, relaying the graphical-screen updates back in the other direction, over a network. VNC is platform-independent – there are clients and servers for. Apple's remote desktop is a VNC client/server package that works with open source VNC. Having that run in addition to another third-party VNC server would just be redundant. OS X comes with a VNC server built-in, and screen sharing is the simple client for viewing that server, but other VNC clients should be able to connect with proper. In this video, we'll show you how to start a screen sharing session to a remote computer you own or manage, using the device access capability built in to VN. Chaos control for windows pc.
There seems to be some major changes from CentOS 6 to CentOS 7 (my current installation, with GNOME), judging by most of the information I've found via googling-- including several changes on this very topic, hence this post to help clear up confusion. Even the information on the CentOS wiki seems not to match my experience with 7, so I can only assume it's out of date.There is some form of screen sharing (as it is called..looking at the repos, it seems to be a minimal version of tigervnc --but I could be wrong on that!) built in to CentOS 7 (so it seems redundant, counter-productive & possibly a source of issues, to install a separate VNC/remote desktop server, as many guides suggest) :
The build in solution can be found by opening settings (click on the username in the top right to open a menu) --> Sharing (towards the bottom of that page) --> screen sharing
Mine is currently set to 'stupidly promiscuous mode' (no password, accept all connections) for testing, and will be changed once I make a connection.
Despite this service being enabled, VNC Viewer is not seeing anything (timing out)
I eventually stumbled onto a firewall, and changed those settings to allow VNC-Server through. (You'd think there'd be some mention of that when you enable the service). And that seems to have helped, as it changed the error from 'machine not found' to 'Unable to connect to VNC Server using your chosen security settings'. Except the default setting is 'Let VNC Server choose' and i've tried 'Prefer off' with the same success as well.
It's unclear to me why VNC Viewer cannot connect to my CentOS box..is there another service interfering..is there more I need to do with the firewall..is 'screen sharing' have some known issue I can't find.. Thanks to everyone who answers and I appreciate the help I advance.
Point of interests:
*Both machines are running on bare metal, I'm having enough problems without involving VMs (at the moment) thanks :p
*I used the full CentOS installation with default (GNOME?) desktop. I can double check if it's that important.
*Despite the prompts in CentOS, I CANNOT connect using my machine name as the VNC Viewer (in fairness, I can't connect at all) as I get a no server found error using the machine name, whereas IP seems to at least find the Machine/Service. Not sure why there is a discrepancy

*I have two users on my CentOS box, one admin, one standard user. The Standard user logs-in by default but both accounts have passwords.*If this ends up being some form of extended firewall issue, would I be better off just turning the CentOS firewall off altogether? As this machine is on a trusted network & behind a router with a firewall anyway..

Apple's remote desktop is a VNC client/server package that works with open source VNC. Having that run in addition to another third-party VNC server would just be redundant. OS X comes with a VNC server built-in, and screen sharing is the simple client for viewing that server, but other VNC clients should be able to connect with proper authentication. Apple Remote Desktop has a bunch of other features built into it, such as taking complete control of a remote computer, freezing the screen, managing installations and file transfers, and a bunch of other stuff.
With Leopard you do not need the Vine Server.
