So far no problems, but I've been on 1.4.3.6 for only a couple weeks.
Fingers crossed.

@gneuner: Have you tried with UltraVNC 1.4.2.0?
It has been solved?


Hi,

I tried 1.4.0.9 which was the latest release at the time (1.4.0.10 was still on the developer channel).

It did solve the slow connect but created another problem on a different machine: occasionally it refuses to connect ...

This is removed in the later versions ( current you can download 1.4.0.10 via the forum)

Thanks, I will give a newer version a try.

Hi,


In addition you might want to check your DNS configuration. You were referring to a server machine. Those should usually not only have a forward-DNS but also a reverse-DNS entry.


I was referring to the UVNC server/service to distinguish from the viewer client. These machines all are ...

Hi,

I use UVNC to administer several machines. Since upgrading to 1.4.0.6 (from 1.3.8.1), I suddenly have one LOCAL server that takes a significantly long time to respond to a connect request. Once the connection is established it works fine.

The problem server and viewer both are on wired network ...

Windows Firewall?


All the machines use Avast - Windows firewall is disabled.

So far I can't find anything to explain this. My one "outside the box" thought is that perhaps jumping directly from 1.2.4.0 to 1.3.8.1 introduced some instability on some of the machines. [I've done big jumps like ...

Just had another 1.3.8.1 machine stop responding. I tried the 1.3.9dev5 viewer as suggested with no luck ... it fails just as 1.3.8.1 does.

I had the user verify with tcpview that the server was listening. She sent me a screen capture that showed it was active and marked as listening. I don't know ...

Sorry for delay - I don't seem to be receiving notices when someone posts.


Installed 1.3.8.1 and was testing with a test viewer 1.3.9 dev3 , this generate identical the same logging.
( i know that thereis a compatibility issue with dev 3)
mslogon show the same as in your case.

It looks like it's not longer listening on port 5900 or whatever you use.
*Is the viewer still working local, can you connect to localhost

Unfortunately, I didn't think to try a loopback connection. I keep that disabled normally because some people have been freaked by the resulting "hall of ...

Hi.

I am using UVNC 1.3.8.1 64-bit to remotely administer a number of Windows 10 machines. In the span of a month I've now had the UVNC service simply stop responding on 2 different machines. Apparently it can occur with no warning ... a machine I could access yesterday did not respond today.

Hi all,

re: Windows 7 home [server and client], UltraVNC 1.2.2.1

I've noticed that the viewer process does not always exit after the window closes. After I finish a session sometimes find I have a "zombie" viewer process left over: I can see it in Process Explorer, but it has no window.

On a ...

But does it work with the firewall on? Can't very well turn off protection.

Just tested the 1.2.2.1 on a server 2008R2 this should more or less act as win7
That seems to work and i can connect running uvnc as service. ( after some firewall issue's)
Using the default ini

Yes, 2008RC2 should be the same as Win7. Firewall hmm? I'll have to look at that. Offhand I can't ...

The crash was caused by the keepalive messages sended by the server.
Server update needed, viewer crash caused by server message...

Not sure I understand - hasn't keepalive been in UVNC for a while? 1.2.1.2 has settings for it. And isn't keepalive a standard mechanism? Repeat the last ACK'd TCP ...

Update:

I tried 1.2.2.1 using both 64-bit viewer and 64-bit server. The viewer appears stable when used with its own server. It still crashes when connected to a 1.2.1.7 server.

However, the 1.2.2.1 server does not seem to work on Win7 unless a user is logged in. I did install it as a service and ...

Meantime 1.2.2.1 has been pre-release


I downloaded the 1.2.2.1 pre-release. I have only looked at the viewer so far, but it still does not respect saved connection settings [even ones it saved itself]. It auto selects "best settings" every time.

On a 64-bit client the viewer crashes immediately ...

i can't repeat it...

Does it also crash when you keep the viewer open and don't do anything in the window.
Does the server has some screensaver active?

My vncviewer 1.2.1.7 on a 64-bit host crashes frequently. It happens after a minute or so regardless of being minimized. It's all but unusable ...
