Password (DES vs Plugin)

Hello,

Currently, if the plug-in password is set, the plug-in password is used as authentication method rather than the DES password.
Is it possible to authenticate through the DES password even if the plug-in password is set?

I tested it by modifying the SetDSMPluginStuff() of ClientConnection ...

Re: UltraVNC 1.6.1.0 - Feedbacks

Hello Rudi,

While the server is running, changing the settings will keep it normal. However, if i completely shut down and rerun the server, all settings are initialized. Is this the intended action?

Best Regards

Re: UltraVNC 1.5.0.X-dev - Feedbacks

Hello Rudi,

It's a very minor error, just curious.
In the 50 line of UdpEchoServer.cpp, one mark(") is omitted. is it meant to be?
Every time building a new release version, the same omission causes a compile error.

Re: Multiple pubkeys/pkeys

Hello,

I don't understand the saying that the server only has one key. For the pubkey and pkey generated to work properly, the pubkey must exist in the folder where winvnc.exe is located, and the pkey must exist in the folder where vncviewer.exe is located.

This means that if there are multiple ...

Multiple pubkeys/pkeys

Hello

I've tested the case where the server and client own multiple pkeys and pubkeys, and I've come to the conclusion of the following.
Could you confirm if it's correct?

When the server owns multiple pubkeys, only the pubkey with the fastest name recognizes it as the server's authentication key ...

Re: Strengthen Password

Hello

The feature I requested is to enforce complicated passwords. These functions vary from site to site, but of course, they're also applied to the Ultravnc Forum. As you know, VNC Password only supports up to 8 digits in DES, so it's limited to enforce complicated passwords. Therefore, I think ...

Re: Questions about latest version

I think it still doesn`t work in 1.6.5.0-dev.

1. Even though i set Encryption of Server, Client notify "The insecure connection was refused." when i set "Only allow encrypted servers." in Client.

2. First of all, even if i shut down the feature of Rules, the Allow Action that was previously added ...

Strengthen Password

Hello Sir,

Recent password setting trends are subject to rules such as limiting the minimum number of characters,
including capital letters or including special characters.

Could you add these features to SecureVNCPlugin?

After successfully building winvnc, the followoing error occurs when running the generated winvnc.exe, why? I didn`t touch the code.
Additionally, the recent version on Github has a completely new UI change. Thank you for the upgrade.
