Can I remove authentication using JavaViewer

Post by Nagaraju »

Hi,

I am a Java developer. While using UltraVNC, we have to give password. Can I customise that one without password asking?

Directlly can I connect to remote desk top?

Please clarify on this. It's very urgent.

Thanks & Regards,
Raaj

Yes, without any authentication (no username and password), its has to connect to remote dektop.

It is possible or not?

Please clarify on this.

If yes, what are the changes I have to do?

If no, why?

Thanks & Regards,
Raaj

ultravnc.ini of UltraVNC 1.0.4 RC16
[admin]
AuthRequired=1 <-- change this value to 0

Actually, this not work, UltraVNC ignores this line and always require password.
Sorry, if you have the fix for this bug, you are welcome.

One of the developers no doubt, please try to also understand that this is a spare time project and Im sure if there is a bug then it will be fixed.

Update...

1. close UltraVNC Server or stop uvnc_service

2. ultravnc.ini of UltraVNC 1.0.4 RC16
[admin]
AuthRequired=1 <-- change this value to 0

3. Start uvnc_service or open UltraVNC Server
Remove the VNC password from UltraVNC Server
Stop UltraVNC Server Service or Close UltraVNC Server

4. Open browser an try again, it asks for password, just press OK button or "Enter" key.
I just tested now, it work

The bug is ask password even just press OK, should ignore and go to page.
This is a bug.
