I use remote desktop and tightvnc, and I like tightvnc a little better. It seems to respond to remote commands quicker and is very easy to use. I use both of these programs over my LAN. I have never tried to connect to my computer over WAN using a DNS server.

Carol,

does one have to use a router in order to use tightVNC on a LAN?
I had tightVNC working, but it was across the web, which slowed it down a lot. how does one get it to work through a LAN? can you give me a few hints?

Theo

Of the VNC-variants, I find tightVNC to be the most optimal. Make sure you install the DFMirage mirror driver if you are using it, it is a separate download. Speeds things up a lot and reduces CPU load. Also, you need to be using a tightVNC client to get full advantage of all of tightVNCs performance features, though any VNC client will work.

Windows Remote Desktop (RDP) will usually outperform VNC in general UI usage, but when it comes to non-standard UI components (video, images, the entire backyardEOS (!) UI), it can be a toss up. tightVNCs JPEG compression may help you on a slow link, but if you are on a home network it may not matter.

There are some other things to consider when comparing VNC and RDP. It is a lot easier to share sessions with VNC. In my case I have my ipad and my desktop PC connecting to my netbook outside over VNC. They can all connect at once and see and share the same view. With RDP connecting from one place will usually disconnect the other (I think there may be a way to share, but I've never used it). VNC will work on and with pretty much anything windows, linux, bsd, os x, android, ipad, web. There are vnc servers and clients for pretty much everything.

On the other hand, RDP isn't limited to the resolution of the devices display. My netbook has a tiny little 1024x600 display which some windows don't even fit on correctly, when I connect using RDP I can use whatever resolution I want on the remote display. A 3 year old 1GB netbook it pretty cheap now and is more than powerful enough to run image capture and control software. If you are turned off by the tiny displays and terrible trackpads RDP could be a good solution here, just run it "headless" with the screen closed and interact with it completely over RDP.

I have been using the Mac OS equivalent Share Screen which has been seamless until Mountain Lion upgrade and has become too slow and unstable. Anyone experience this too?

Hi Theo. I do use a wireless router. If you've got it working over the web, then you really have it all set up. I'm assuming your computer has a static IP address. If not, I found it to work better if the computer has a static LAN IP address. When you open the VNC window, just type the LAN IP address. If you have assigned a specific port number to that particular computer, you can enter that too. For example, just type: my IP address:3333. "my IP address" is your computer's LAN IP. When I used remote desktop, I assigned my computer a specific port number to increase security, but that's really not necessary for LAN.

I've never used Tight VNC over the web. I do have an account with DynamicDNS, but have never used it. Could you explain how you get it working over the web? Thanks!!

George,

You are referring to your Mac's built in Screen Sharing which is activated in System Preferences? Are both Macs running OS 10.8? I'm pokey, still using 10.6, but I noticed a number of posts in Apple Support Communities. Try Googling "screen sharing slow mountain lion". Are you connecting via ethernet or WI-FI. WI-Fi users are reporting problems here: https://discussions.apple.com/thread/4151334?start=0&tstart=0

This seems to be an unresolved issue as of now.

In addition to "Screen Sharing", there is Back to My Mac, which requires a free iCloud account with Apple ID (formerly MobileMe). This operates through your Mac's built in Bonjour and can connect any two macs anywhere in the world via the internet. I can't use Back to My Mac due to iCloud's requirement of at least 10.7.

More info here: http://www.apple.com/support/icloud/back-to-my-mac/

Best of Luck,
Michal

"I've never used Tight VNC over the web. I do have an account with DynamicDNS, but have never used it. Could you explain how you get it working over the web? Thanks!! "

Carol,

I don't think you have to have an account to do this.

I have been having problems with my laptop as of late and cannot install VNC, but I will tell you as best I can recall. I think there is 2 modules to it. there is a server and a remote? not sure. but once they are installed, it places an icon on the toolbar. when one places the curser over the icon, it displays the IP address if one is connected to the net. each machine will have a different address. place the IP address from each machine on the opposite and they should connect. maybe one only has to place one opposing IP on one machine, that I am also unsure of, but I think you can get it going with this little bit of info.

my problem is to find my LAN IP. I have gotten the 2 machines to the point of file swapping and such, I think...

I got to get my main machine back in order before I can get to messing with a LAN again.

Theo
