RE: Problem connecting to machine when desktop is locked

I get repeatable disconnects with Dev7;
I've gone back to 1.2.9 on my servers and most of my
machines because of it. Dev6 has an issue with filling
up the Applications log with HHCTRL error messages, so
I'm not using that...

I have one machine that I still have Dev7 on, for the
file transfer function.  I'm using ssh to tunnel into
it, and using the loopback only mode for TightVNC.

I expect the disconnects, so on my home machine
I've saved the settings to this machine.  All I have to
do is re-launch the connection right after the disconnect.

If you do that for the Dev7 machine you referred to
in your post, it's possible that if you reconnect
to it, you'll be looking at the (unlocked) desktop.
That's what happens when I connect to mine for the
second time.

You aren't being refused a connection; something is
happening in Dev7 at certain transition points in
a Windows session, which terminate the connection;

1.  going from a locked to unlocking state
2.  going from logged off to a logon state
3.  going from logged on to a logoff state
4.  going from an unlocked to locking state

RE: Does VNC capture hardware, 3d-accelerated video.

I suppose the obvious question now is whether or not modern hardware 3D
acceleration cards write the accelerated data to the video buffer that
VNC monitors.  Does anyone have any idea?

Also, does the use of alternate monitoring methods like TightVNC's
dfmirage hook driver affect what VNC might see in this situation?

Changing the default TightVNC password

Hi,

We have been using TightVNC 1.2.5 for remote HelpDesk support on 500+ PCs
spread across 45 different locations for some time now.

The problem I do have however is when I change the default TightVNC password
on a new PC running Win XP Pro SP2.

The PCs are all deployed from an Altiris Image and then added to the domain
and configured before being deployed to the end user.

The Altiris image is created prior to the PC being added onto the domain -
all the required software is installed   upon the PC under a test admin
logon and then once everything has been setup and configured (including
TightVNC which is set to run as a service) the test admin profile is copied
into the default user profile and an image created.

Once the image has been deployed the PC has it's SID changed and is added to
the domain. At this point the default TightVNC password is reset to the one
assigned to that PC asset number.

To change the TightVNC passwords the following commands are used:

C:\Program Files\Tightvnc\winvnc -settings
C:\Program Files\Tightvnc\winvnc -defaultsettings

As I understand it this changes the password for the currently logged on
user (being the PC's local admin logon) and the default password.

If I VNC onto the PC after this the new password works perfectly  - likewise

RE: Changing the default TightVNC password

Login as the local user...

Change the password

Run REGEDT32

Open HKEY_Current_user\SOFTWARE\ORL\WinVNC3\Password

Copy the string to your clipboard

Open HKEY_LOCAL_Machine\SOFTWARE\ORL\WinVNC3\Default\Password

Paste the contents into the Password field

Good luck!

Cary,

Is there some reason why you can't just disable per-user properties?

Re: No Action From VNCConnect

Sorry for the top post, but my past two posts below have been ignored.  I need 
to be able to use remote access, and I'm getting no help on TightVNC, so I 
need to know if I can get help or have to decide TIghtVNC can't handle this.  
I'd rather put the parts that have already been ignored at the bottom of the 
post.

Okay, I'm having no luck and I need to get this working.  I don't know where 
to go, other than directly to the program authors (who may or may not be on 
this list) to find out how to do this.  I can understand that people might 
not be sure about vncconnect, but I'd think that at least someone on this 
list could suggest (when I asked) a better place to go for help.  (Not one 
response on this -- in public or private!)  I have to admit I'm very 
frustrated that in 2 weeks, there are no responses, and not even suggestions 
on where I can get help on this -- or even a response to say whether or not 
this list handles problems like this.  While people may not know the answer 
to my problem, I'm disappointed I didn't get even one response to "Is this 
list the place to ask for support on a problem like this?  If not, is there 
someone or some group I should contact directly?"  I need help to get this to 
work, and if 

Is there at least anyone who uses a TightVNC server on Linux and, instead of 
having clients make the connection, has the server add or contact clients?

I *NEED* to get this problem resolved, and since I cannot get any info on 
this, can someone at least answer any of these questions:

1) If I use vncconnect, do I need to have the server already running on that 
system, or does it start its own instance of the TightVNC server?

2) If vncconnect gives no status and no error message -- no output at all --

RE: No Action From VNCConnect

Hal,

Have you tried upgrading to VNC 4.1.1
(http://www.realvnc.com/products/free/4.1) and using "vncconfig -connect" in
place of "vncconnect"?

Cheers,

The tone of you message got my attention.  I understand that your fustrated.
But I don't understand you demanding that I (or others) give you our free time
to solve your problems.  Then again, it did get my attention.

Personally I've never done a vncconnect from linux.  I've never found it 
necesary as it is so easy to setup the ssh server to allow me in, with the 
additional advantage of encryption.  If your clients can allow ssh through 
to one machine, you can use it to access all others.

I could help you set that up.

Other than that, I all I can offer is to try to get it working my network.

RE: No Action From VNCConnect

Hal:
I saw that Wez replied with a suggestion to switch to "RealVNC" 4.1 and use
"vncconfig -connect" instead of "vncconnect." That being said, WHY do you
want to connect a server to a client instead of the client to the server? I
know that some distributions have a "remote assistance" app based on VNC,
but for the life of me, I can't recall what it is... maybe that would work
for you? I believe that you send an invitation to someone to connect to your
desktop, but as I say, I haven't used it...
Further, you could just have the client/viewer connect via SSH and tunnel
the VNC connection through SSH. There are several apps that'll do that all
in one package for you, or you can do 'em separately using PuTTY and SSH.
Whatever you choose to do, good luck!
	John

I must have been working with old bookmarks a few weeks ago.  I installed tvnc 
with apt-get (on Debian Linux), and I had gone through several web pages on 
it, but it must have been an old site (or who knows what), since the realvnc 
site is not at all what I found before.

I've got it and I'm looking it over.  I downloaded the Windows and Linux 
versions.  I got the Windows zip file, but it unpacks to an exe file.  Any 
idea what format the exe file is packed in?  It'll be a while before I can 
use a Windows system and I want to see the files and info in it.

When I've had time to test this and work with it, I'll update the list on it.

Thanks for a good pointer!

Hal
