Ask Slashdot: Easy, Open Source Desktop-Sharing Software? 116

N8F8 writes "Like many IT professionals, I provide a lot of free help desk-type support to friends and family. I've decided to expand my support work and create a site where veterans can receive free computer help. I'm using OSTicket for the ticket reporting. What I really need is an easy to use desktop-sharing system. In the past I've used TeamViewer because it is easy to use, but it is not really free for non-personal use. Recently I switched to Meraki Systems Manager because it is free — and it uses VNC — but unfortunately it isn't intended for the one-time-use type support I'll be offering. So I'm looking for a reliable, open source, easy to use desktop-sharing solution that I can set up on my site for people to join one-time-use help desk sessions."

      +1. This is the obvious answer.

      The optics are great (veterans, help, non-profit.)

      First, fix your website so that it is obvious what you are offering and how you deliver it ("we are off-line now" does not cut it.)

      Second, send a mail to TeamViewer's CEO or PR explaining what you do, what you need, and how you can help them in the PR space (you put thanks on your site, they can point to you as a good deed, you are available for journalists.)

      Better than a shot, it should be a slam-dunk if you do it right.

    ChunkVNC + Instant Support is great and can be found here: http://www.chunkvnc.com/ [chunkvnc.com] Do yourself a favor and click the "Help" at the top of the page to get to the forums and look for rat's 4.0 fork.

    Basically what you do is run a repeater on an internet accessable box, use the scripts to customize and create a small (2mb usually) "instantsupport.exe" that you can link on a website somewhere, and then when the user runs it, they either pick a support technician, or get an ID number that you use to connect to them, through the repeater, using the chunk viewer.

      Unfortunately, the repeater is a Windows program. That is what you need to run on a server with a fixed IP. If you already have a server somewhere with a fixed IP, chances are high that it runs Linux or some BSD.

      I once set up a very simple repeater on my Debian server, to use with UltraVNC (which is what ChunkVNC uses). It worked, but there were no easy instructions on how to set it up, or how to pre-configure the Windows UltraVNC endpoints. Also, if I remember correctly, it only supported one connection at

    UltraVNC Single Click [uvnc.com] is a small (Win) executable customized to connect the user to your address. You run VNC Viewer in "listen" mode. It's very simple to use, doesn't require installing, can be downloaded by the user or sent via email (if they can receive .exe files), works through user NAT. I've been using it for years, directed to my dynamic IP via dyndns. You can customize what the user client looks like. Don't know if it works with Win8 though, and it doesn't work for users running OSX or Linux.

        His method uses the client in listen mode though. This is the solution I was going to suggest. It's simple to write a small self-extracting executable that contains the VNC server and launches it with parameters telling it to connect to the client. I even had it integrated with our helpdesk software so that the helpdesk people could choose to pick up the connections (the software I wrote to launch the server would actually wait until one of the helpdesk people "accepted" the user before launching the server).

      This is what we use at our shop, but it's gone way downhill recently. There is now a problem/bug somewhere, either in a recent update of the client or in MS's implementation of UAC, that prevents you from controlling anything that requires admin permissions remotely. This happens even when UAC is fully disabled as far as I've seen. It used to just bring up the standard UAC prompt ("do you want to do this thing") that we couldn't see or click on, but once you got through it everything worked well.

          That's interesting. Perhaps they need to re-install UltraVNC as an administrator and install the mirror driver as administrator.

          I get UAC prompts over UltraVNC every day and it does definitely work. I just did one now. UltraVNC works.

          • We use the single click executable (as mentioned in the parent comment). This doesn't actually install - it's a standalone exe. We run VNC in listen mode on our tech stations at the shop, and tell the customer over the phone who to click on to let us in. So, a reinstall won't help here.

              Sorry, I thought I had read it clearly.

              Using the .exe is never going to work just like the others said.

    • I can second this recommendation, as long as users are on Windows, which I'm guessing they most likely are.

      Once it's setup, it really is as simple as VNC can possibly be for users (literally, just: go to this website, download this file, click yes/allow to any security warnings).

      That said, it's pretty amazing how difficult it is to talk some users through something as simple as this, but I guess it's not easy explaining anything technical to people who think their computer is a glorified dishwasher.
