UltraVNC

It also seems (from the MSDN thread) that the stub launcher API call will fail if no-one is logged on, so it will be impossible to serve the initial logon screen.

I use UltraVNC server and viewer from BartPE bootable CD. There is a standard plugin for UltraVNC. Google for BartPE. It's free (need Windows license for the PC you boot the CD from).

Good luck

I second this feature request

Sorry, but it is not clear what you want to accomplish.

VNC is typically used to access the console, and it works as long as the console is also session 0.

What would be the desired benefit of -noconsole? What would you expect to see?

As VNC works right now, what you get is the screen from ...

>This is a screen shot from systernals tcp port monitor after closing winvnc.exe from both a GUI and or stoping winvnc.exe -service. So when I try to start the service again it says winvnc.exe is already running when it is not.

You had connections to/from localhost in TIME_WAIT. This is normal, but ...

I have not tried to record via the JAVA viewer until today. While recording was active, I could not interact with the JAVA viewer at all. I suppose one has to have two sessions in parallel, one for interacting and the other for recording.

I checked the content of the recorded file, and it was ...

Try using ZoomIt from http://sysinternals.com on the clients' screen
(I suppose that means the PC running VNC server).

It has a temporary "draw" mode that works fine.

Good luck

If the problem is the popup just after installation, then try searching for fastpush.

If you want to do something yourself, then you can avoid the popup by following this recipe:

Preparation in advance:
(optionally run UltraVncDriverSetupSilent /verysilent)
Install and configure manually a ...

Bump,

though I understand if there is a little too much activity in the forum right now...

Hello,

I'm implementing SC for helpdesk support.
The fact that SC is not listening is crucial for internal sec. audit.

However during a support session it must NOT be possible for supporter to blank the screen of the server - the supportee must be observing anything done in his/her name.

I tried ...

IP addresses for uvnc connections are logged to eventviewer.

Trouble for us is that IP adresses change every few hours because of DHCP.

It would be great to have DNS names logged as well!

I googled for multicast vnc and up came among others

http://www2.in.tum.de/~ziewer/multicastvnc/

I don't know how or if they handle lost packets.

I used htthost/httport long ago for VNC forwarding.

You need to install htthost on a PC, who is generally accessible on the internet - typically your "home" PC. This means that if you started a webserver on the home PC, everyone else must be able to connect to it. There are two showstoppers for ...

Well,

Ultra ScreenRecorder is a great product, but it is more in the league of DemoForge. It is both overkill and not quite enough, as it can in principle miss some updates, that went to the consultants' screen.

Already record/replay seems to work for me (with some limitations) just by replaying ...

Yeah, my little program only forwards data, too. That is why I need ways to ensure, that the server only sends replayable data.

Unfortunately the viewer is by nature in the hands of the consultant, whose actions I am supposed to be able to audit. Of course I can make him promise to record his ...

Hi,

this is a many-folded request for a "replayability option".

I managed to record and save VNC traffic and replay it later to a viewer - required for auditing purposes. On the viewer side, I had to choose a specific Encoding, refrain from using encryption and file transfer etc. I imagine that ...

Actually our external consultants want to use RDP (Remote Desktop), but RDP cannot be replayed, and as we use UltraVnc in general, I am going to use a VNCviewer instead of Explorer.exe for the RDP sessions.


Btw, RDP can REALLY be replayed.
Just look at our DemoForge Studio ( http://www ...

Hi,

I need record/replay for auditing external consultants' sessions.

I built a quick TCP forwarder (like the repeater), which saves the session traffic to a file. For each buffer forwarded, a fixed header with direction, timestamp and bufferlength preceeds the stored buffer.

During replay, any ...

Right of course, that is, if your proxy is open for outgoing SSH on port 22. Ours, for example, supports http/https on port 80/443 only.

If you need to tunnel the VNC connection through the proxy as well,
look at http or https tunneling with f.ex. www.htthost.com

Well I am thinking about recording also; we want to be able to record VNC and RDP (Windows Terminal Services) sessions for documentation and auditing purposes, but there is not much around.

I have been thinking along a simple general TCP forwarder with simultaneous recording to a file with ...

Lizard,

I downloaded your 1.00b mod and tried it, looks good, but:

In Danish, to type a backslash \ you need to use the combo

AltGr+< (press the < left of Z while holding down the AltGr right of Space)

which work fine with UltraVNC Release 1.00 but not with your mod.

I guess it could be a side ...

have you considered psexec from the pstools at www.sysinternals.com? That's what I use (provided you can access the server with local admin credentials).

Multicast for classroom teaching is a great idea; only problem is that multicast is a type of UDP => not guaranteed delivery.

So some kind of retransmission scheme must be implemented, similar to NAT traversal with UDP packets, but with new interesting challenges:

- how to handle latecomers (new ...

Now HTTP-tunneling is technically rather easy.

There is a free SSH/SSHD-like pair of utilities at

http://www.htthost.com

called httport/htthost - I have tried them, rather easy.

But httport has to be configured with the client's http proxy address also;
it would be nice to have configured ...

Sorry for a long reply:

It has long since been inherent in the RFB protocol that framebuffer updates are only sent upon receiving a update request; it is part of the "automatic" adaptation to the transfer speed. And it works just fine for slow bandwidth with low latency.

I have experienced myself ...

Rrrright, thanks

Someone could perhaps make a DSM using ZeBeDeeLib...

Thanks for the reply,

which I interpret as a "no" to sound output forwarding,
but a "yes" to voice chat.
