Hallo people,

I'm working with WinVNC and now i want make some change about the password. How can with kix change the password in the registry?

Also i want to have i script for on authorized access to VNC. Because by VNC you dont have to anser a question if people can view or take over your screen. Is it possible to create script witch shows the standard desktop by the viewer site so a fake screen. And i can normally going on with my work and they will not see than for example my mail this is privacy. Or is it possible that we must confirm that someone else can see my screen or take over my screen.

Thanks. [Smile]

Howdie,

the first thing is simple... [Wink] Are you using the official VNC package? Then install it on a dummy PC, change the password and search the registry for password or something like that (something with ORL I think.)

Then copy/writedown the password's value and write in your script a line which writes the data in the registry (with writevalue). Since the password is encrypted you can't just enter the password in the registry, you'd have to use the encrypted data.

I'm not sure what you're trying to accomplish in the second part [Confused] . Can you be more specific?

PS.
If it doesn't work you could also mail me (ook in het Nederlands). Afterwards we can put the solution to the board.

Search the forums for examples of installing WinVNC automatically. I posted an example script some time ago to do it which set various parameters including the password.

I don't think that it is possible to pop up a message warning you if someone is trying to connect - it's not really what VNC was developed for.

use this tool...

http://www.systemtools.com/strcm/strcm_frame.htm

I no longer worry about setting up the software on a PC... this pushes it, sets it up, connects to it, and then removes it.

Much better from a security standpoint.

I use WinVNC. The icon for WinVNC changes color when someone is attached to your computer. As far as I know you can't turn off this feature.

there was discussion on bell labs site regarding this 'feature'.

They made sure to point out that this was an admin tool, not a potential 'spying' tool.

I had some managers who didn't like the idea of me having the ability to spy on their computer even though there is a visual indicator. I simply told them to change the password to anything; they didn't even have to remember the thing. I told them that anytime they needed my help all they had to do was change the password to something simple, let me know, let me do my work, then change the password again. That placated their fears.

Here is some code out of one of my scripts.

code:
$RC = WriteValue ('\\$Computer\HKEY_LOCAL_MACHINE\SOFTWARE\ORL\WinVNC3', 'DisableTrayIcon', '0', 'REG_DWORD')

The Icon does not show up in the System Tray.

YES YOU CAN PROMT THE USER FOR PERMISSION!!

From the Documentation...

AuthHosts
The AuthHosts setting is, unlike the other
settings, a REG_SZ string. It is used to specify
a set of IP address templates which incoming
connections must match in order to be accepted.
By default, the template is empty and
connections from all hosts are accepted. The
template is of the form:
+[ip-address-template]
?[ip-address-template]
-[ip-address-template]
In the above, [ip-address-template] represents
the leftmost bytes of the desired stringified IP
address. For example, +158.97 would match both
158.97.12.10 and 158.97.14.2. Multiple match
terms may be specified, delimited by the ":"
character. Terms appearing later in the template
take precedence over earlier ones. e.g. -:+158.97:
would filter out all incoming connections except
those beginning with 158.97. Terms beginning
with the "?" character are treated by default as
indicating hosts from whom connections must be
accepted at the server side via a dialog box.
The QuerySetting option determines the precise
behaviour of the three AuthHosts options.
Local machine-specific setting.

QuerySetting
The QuerySetting allows individual users to
tailor the degree of paranoia expressed by the
per-machine AuthHosts setting. It is a DWORD
value ranging from zero (maximum availability)
to four (maximum security). The following table
indicates how the value affects the AuthHosts
behaviour:
0 - +:Accept, ?:Accept, -:Query
1 - +:Accept, ?:Accept, -:Reject
2 - +:Accept, ?:Query, -:Reject [Default]
3 - +:Query, ?:Query, -:Reject
4 - +:Query, ?:Reject, -:Reject
By default, value 2 (Obey AuthHosts) will be
assumed. Local & global per-user setting.

QueryTimeout
The QueryTimeout setting indicates the number of
seconds for which the Accept Connection dialog
(see AuthHosts and QuerySetting options) will be
displayed before rejecting the incoming
connection automatically. Local & global
per-user setting.


What the registry looks like...

[HKEY_LOCAL_MACHINE\SOFTWARE\ORL\WinVNC3\Default]

"QuerySetting"=dword:00000003
"QueryTimeout"=dword:00000014
"AuthHosts"="?xxx.xxx,?xxx.xxx" <- Your networks IP address[s]
