I am using it instead of TeamViewer.
/I'm using it with NoIP/
Highly Recommended for Windows!
This is what you get when you click the "Download" button on the UltraVNC website.
If you click "UltraVNC" on the top of the page, and then click through two more (seemingly unnecessary) webpages, you end up here.
Believe me, this was very confusing the first time I saw it-- the notification at the bottom is almost unnoticeable. The design of this page is more like the webpages of 4Shared or Hotfile, not of a website for legitimate software like UltraVNC. I ended up just downloading it through FileHippo... seriously UltraVNC website, Y U SO CONFUSING?
Seriously, you should ask for a refund. sigh
You'd think that UltraVNC would actually want a lot of people to try out their software, instead of forcing new users to jump through a bunch of hoops just to download it at all.
Not only is it ugly and obfuscated, the Download button at the bottom of the page DOESN"T EVEN WORK. You click it and it pops up their home page in a new tab. Idiots. If they can't even make a working website, why should I trust them to run networking software on my computer?
It's been improved since then, but I agree that it still sucks. The whole site looks and behaves like crap, and could use a major overhaul.
It's good enough. I use it (client part) to access a machine in another room and it has been working reliably for many many years. I also have used the server. It is easy to configure but you just need to be careful not to download junk from the website hosting it.
Though quite effective once it is set up, UltraVNC's approach to setting up remote screen viewing can be considered cumbersome to even veteran computer users, making one of the most prominent uses for remote computer access software, remote troubleshooting, best left to another app. The likes of
AnyDesk are more viable for that use case.
Requires static IP or using prepaid DynDNS-service. So it can't replace TeamViewer, etc. Period.
I've been (sadly) reliant on this software for some time and have only stuck with it because of the collaborative nature by which it is being developed. It is an active forum, but it must be said it's the same few people who report bugs in all the time, of which I was one - very much of the belief that together we could contribute to an awesome application
I'm a huge fan of the open source principles, but say for example, if the primary developer is permanently high, there's only so much the community can contribute, short of an intervention...
What's completely disheartening, and why this project should be avoided, is the main (or only) developer's modus operandi. Put simply, he's not a completist, so this project will only ever be partially useable. It is unarguably true that older versions are more stable than newer ones. Of course, new operating systems introduce new problems but the communication layer between client and server should be isolated from this. Yet, there are continual instabilities, bizarre behaviour, very tricky to reproduce bugs, memory leaks, inconsistencies between packages... you name it, any numbers of versions have got it
Do yourself a favour and adopt any other project; it's guaranteed to have far more organised and sensible developers behind it
Well, I am not using the Server function. I only use the viewer. Tried TightVNC and RealVNC and this one is the best to access my local server. Very good transcoding speed, for this tiny client.
