Re: Very slow UltraVNC when network adapters are combined with a virtual bridge

There are many posts on the net that sometimes virtual bridges are slow for tcp .
I'm not a bridge specialist but it seems to happen when there are routing issue's.

Google "virtual bridge microsoft slow"

Re: UltraVNC 1.5.0.4-dev - Feedbacks

I don't think the cpu of the viewer can have any influence. You can connect using unix/mac/ and all implementations are different.
It looks more like a network issue.

On of the dev pc is a 128core (amd hyperthread) and as viewer i use a i7, this works without an issue. ( LAN connection)

Re: UltraVNC 1.5.0.4-dev - Feedbacks

service will be changed like this

%programdata%\UltraVNC\ultravnc.ini
but when you install it with another name sample: "myvnc_service"
%programdata%\UltraVNC\myvnc_service.ini
is used

When not found it fallback to current folder

This should do the trick for multiple installed services

Re: No login with Encryption

When encryption is active the pasword is used to create an encryption key.
The encryption is secure, even with a 8 char passwd but using brute force 8 char passwords are easy broken as the combination is limited.

That's ok for internal use, but on a open server should set a phassphraze
