 TightVNC 1.2.3 (Default)
Section: Unix

 

Added: Wed, Aug 23rd 2000 12:11 UTC (7 years, 11 months ago) Updated: Mon, May 7th 2007 21:49 UTC (1 year, 2 months ago)


Screenshot About:
TightVNC is a VNC distribution with many new features, improvements, and bugfixes over VNC. It is optimized for faster operation on slow network links such as modem connections, provides more configuration options in the server, features automatic SSH tunneling in the Unix vncviewer, and more. The modified servers and viewers are fully compatible with the original VNC software.

Release focus: Major feature enhancements

Changes:
This release features a greatly improved Java viewer and support for wheel mouse events in the Win32 version. Two important security problems were also fixed: the zlib double free() bug and blocking I/O in the built-in HTTP servers. Several patches from the Red Hat vnc RPMs were incorporated into the main codebase. Manual pages for the Unix version were prepared. Other changes include the usual minor improvements, bugfixes, and cleanups.

[»] Unable to connect to server
by BillyNoPubs - Feb 5th 2008 06:24:36

I recently replaced a Windows 2000 PC (at a remote location) with another because of hardware problems. I was able to control the "old" W2K PC using the installed TightVNC 1.2.9 running as a service. I'm not able to directly control the "new" PC using TightVNC, the connection times out. Nothing has changed on the firewall so it's not a firewall issue.

Nor is it a TightVNC server issue since I'm able to remotely control the PC through a TightVNC viewer session established on another PC in the remote workgroup. This is a horrible way of doing the job, the screen refresh is slow and erratic.

Is there an obvious answer to this? Or is there some diagnostic information that I can access which will help in troubleshooting? Deinstalling and reinstalling TightVNC doesn't help.

Oops, another typo. It should be VNCviewer.exe not VNCviewer.dll
Also, I've discovered that to make the final exe run under Vista (no problem under XP), you need to create two .reg files out of two WinVNC folders from the registry, one under HKEY_CURRENT_USER and the second one under HKEY_LOCAL_MACHINE. There is a third one under HKEY_USERS that can be ignored. Name the two reg files: WinVNC.reg and WinVNC2.reg

Modify the bat file contents to read:

%myfiles%\regedit.exe /s winvnc.reg
ping -n 1 127.0.0.1
%myfiles%\regedit.exe /s winvnc2.reg
ping -n 1 127.0.0.1
start %myfiles%\winVnc.exe
ping -n 2 127.0.0.1
%myfiles%\WinVNC.exe -connect 70.112.yyy.xxx::5500

Follow previous instructions.

Good Luck

    TNX FOR THIS MAN!
    in just have to give you some feedback. this actually does work. just need to test it on vista to.
    it's like you said - you usually spend more time on telling a customer on how to connect you with "add new client" than the actual problem is.

    thanks again! and keep up the good work.

      just another question ...

      any idea how to solve this:
      when the customer runs this bundled exe, it brings him up tightvnc server and connects to vnc client on my computer. when connection is closed, the server is still running at my customers computer. if my client clicks the exe (the one we speak of here) again it crashes and shows an error. customer must close the server and click the exe one more time to load the server again and connect.

      is there an elegant way to check if the server is already running before it connects to client? it would be nice that the client does not see any error messages. it scares them. :)

        Yes, I have run into this issue myself but don't have a solution. Since I'm controlling the remote computer, I just close out the application from the tool bar (bottom right) myself which immediately breaks the connection. FYI, I've posted a set of highly detailed and highly simplified instructions on how to create the reversevnc files on my family homepage. http://brettschneider.us/ReverseVNC_Instructions/reversevnc.html

[»] Simple Stand Alone Reverse VNC Connection File Typo
by r11532 - May 16th 2007 21:40:33

OOPS

I made a typo. The line below in my May 10, 2007 comments were:

%myfiles%regedit.exe /s WinVNC.reg

Should have been:

%myfiles%\regedit.exe /s WinVNC.reg

Again, my reason for making a single executable was to simplify the reverse vnc process, which I used this very evening to help a relative install a webcam. The appearance of the application icon in the taskbar and likelihood that the firewall requesting permission to allow a connection should be enough alert to prevent abuse. But, with some of the tools available and some trickery, anything is possible I suppose.

Good luck all,

[»] Simple Stand Alone Reverse VNC Connection File
by r11532 - May 10th 2007 11:51:04

I'm frequently asked for help in solving computer problems by family members. In theory the easiest way to help is by setting up a reverse VNC link so I can help remotely. Often, however, the process of talking a relative through the reverse process is harder than solving the original problem.

After being unable to find instructions on the Internet on how to create a single executable file to simplify establishing reverse VNC connections, I decided to do it myself.

"How to make a simple stand alone reverse vnc startup program file and to setup a host computer for the reverse vnc connection."

This may not be the only or the simplest way to make a stand alone reverse vnc start up file but it works for me.

1. Download tightvnc-1.3.8_x86.zip or latest version from TightVNC.
Extract WinVNC.exe, VNChooks.dll and VNCviewer.dll
Obtain a copy of Regedit.exe
2. Install and Use PEBundle to merge WinVNC.exe with VNChooks.dll into a new stand alone WinVNC.exe
Choose option: "do not write module to disk."
3. Install and Use AbyssMedia Quick Batch File Compiler to compile our bat file into an exe
"Include" the stand alone WinVNC.exe, Regedit.exe and WinVNC.reg files
Choose option: "Ghost Application." (see info. on the reg and bat files below)

If you register PEBundle and Quick Batch File Compiler, there will be no popup registration reminders when
the final stand alone executable file is run.

To generate the WinVNC.reg, run the stand alone WinVNC.exe for first time to bring up it's configuration options.
Enter any values into the password fields and click OK. Run Regedit and locate ORL folder in registry.
Right click on WinVNC3 folder and export to desktop. Rename to WinVNC.reg

Create a WinVNC.bat file that contains the following commands for compiling by the Quick Batch File Compiler:

%myfiles%regedit.exe /s WinVNC.reg
ping -n 2 127.0.0.1
start %myfiles%\WinVNC.exe
ping -n 2 127.0.0.1
%myfiles%\WinVNC.exe -connect 70.112.yyy.xxx::5500

where 70.112.yyy.xxx is an example internet ip address. Change it to the ip address of your host computer or network.

Make a VNCviewer.bat file to start the VNCviewer.exe on the host computer with contents:

start VNCviewer.exe -listen

Run the bat file to start listening.

Setup your host router, if one is used, to accept port forwarding of port 5500 to your host computer's
internal ip address.

Email the exe file created in step 3. to the operator of the client computer with instructions to run the program and
to answer yes or OK to all messages that pop up especially the one giving permission to pass through their firewall,
if one is installed.

If the reverse vnc startup program file works as created, the total time needed by the client computer operator to
establish a reverse connection will only be a few seconds.

    While I think there is a reason for a simple executable to not be distributed (it would widely be misused), a solution like this one makes sense. Good tutorial.

    I visited tightvnc site and I can download version 1.3.9, not 1.3.8
    The latest version does not have VNCviewer.dll, instead there is vncviewer.exe

    Does this .exe module work the same way as .dll module?
    Or should I get version 1.3.8? I do not know where can I get it.

That way you'd be able to log-in/log-out without losing a connection and be able to reboot the computer and then log back on.

[»] Newsbin Pro & TightVNC
by Bruce - Dec 14th 2004 12:04:36

Constantin,

Have you done any testing with Newsbin Pro 4.32 (or other versions) and TightVNC (also any version) running simultaneously? Maybe you can give it a shot and run these on your debuggers to see what's causing the problem at least.

CPU usage goes to 100% if I connect remotely to my winvnc.exe and I'm downloading some binaries from any newsgroup using nbpro.exe. If I close Newsbin the CPU goes back to normal. If I close all winvnc connections while nbpro.exe is running the CPU goes back to normal. The moment that nbpro.exe is running and I make a connection remotely, CPU usage is constantly at 100%. Newsbin guys are telling me it's a Tight/WinVNC problem. I'm not convinced it is but it may be true.

Any thoughts or comments on this? I've reported this as a tightvnc bug at sourceforge already.

There's also a large thread on this at:

http://forum.newsbin.com/viewtopic.php?t=11961

I'm following that thread closely and there's no solution or workaround.

I use the on-screen-keyboard(osk) that is in Windows XP due to my handicap (mobility impairment). If I use the tightvnc viewer full screen , i cannot use the osk on the viewer's computer but only the osk on the vnc-server computer. The ctrl-esc-esc method to disable full screen does not work.

    In the latest version of the viewer, there is another way to exit from the full-screen mode - the Ctrl-Alt-Shift-F hotkey. But I'm not sure it would be easy or possible to use it with on-screen keyboard...

But we want to do it the other way: have a web browser connect to a computer with the program installed on it(server if you like), and the server controll the computer through the browser (but with no specific software installed on it). Does any one know how to do this with VNC or any other program?

    I think currently that's not possible, and I doubt it can be done at all. To share the desktop, you'll have to run some software on that machine. Maybe a sort of ActiveX control could do that, but I'm not sure.

      I think it is a great idea, and I have been working on a solution the past week. There is a company that does it, called Desktop Streaming. It basically pushes a small app to the user, and once they receive it, it opens up, and they press connect. It connects to the viewer side, and then I have control of their desktop. Works great for desktop support, but I have not been able to find a free one. I will need a few more weeks until I can get it finished. I will post when im done... Also, if anyone has any ideas, please inform me. Any help would be greatly appreciated

    You can do what you want with VNC. Just get the user to start the VNC server and then you can connect to it and control his or her machine. To make it more convenient you could generate a VNC server binary that's hardcoded to accept connections with a certain password (hopefully a different password for each user that downloads!). You could make the VNC server into a single executable which starts running immediately, and put this as a download link on your web page.

[»] VNCViewer in listen mode over SSH
by Dan - Oct 30th 2002 22:48:15

At the moment it doesnt seem possible to run the viewer (windows version) in listen mode and then have a server initiate a connection to it over SSH. I have tried using the the "allowloopback" entry in the registry and changing the default port number for the server on the listening machine also (it runs both the viewer and the vncviewer listening daemon), and every time I initiate a secure connection, I get "Loopback not allowed". I am running openssh on the listening machine (win2k) and initiating secure connections using putty. The port forward is currently set to 5500 although I have tried numerous variations using the + number of desktop variable on both putty and vncviewer /listen to no avail. Will this be a consideration in future releases or does someone have a fix for this already? Straight VNC over SSH works a treat, so why not the viewer in listen mode?

    Hi Dan!
    This works for me.
    My configuration #1:
    -Alice - running TightVNC server with AllowLoopback option enabled (WinME)
    -Charlie - running TightVNC in listen mode and WinSSHD in SSH2 (W2000)

    I use PuTTY to open the connection from Alice to Charlie, forwarding Alices's port 5500 to Charlies port 5500.
    The "Forwarded ports:" window should say:
    L5500 Charlie:5500
    On Alice I add client Bob and the vnc listener opens at Charlie.

    My configuration #2:
    -Alice - running TightVNC server (does not need AllowLoopback)(WinME)
    -Bob - running WinSSHD in SSH2 (W2000)
    -Charlie - running TightVNC in listen mode (W2000)

    I use PuTTY to open the connection from Charlie to Bob, forwarding Bob's port 5500 to Charlies port 5500 , remeber to check the "remote ports do the same[SSH v2 only]", (you are running SSH2?) .
    The "Forwarded ports:" window should say:
    R5500 localhost:5500
    On Alice I add client Bob and the vnc listener opens at Charlie.

      The TightVNC client to be added should be localhost (or 127.0.0.1) instead of Bob.

[»] Icon in Service Tray
by dcoleman1us - Oct 23rd 2002 09:08:32

I don't want the user to see the icon which shows up on their taskbar in the system tray. Question, how do I remove the icon but still allow the program to run in the background so the user doesn't know it. I use this program in a classroom setting to monitor student activity as well as maintaining / troubleshooting. If it were WINXP, I would just right click the system tray and go to properties and then to customize. These work stations are NT4. Any help would be appreciated.

    I don't think it's a good idea to hide the fact that TightVNC is running from users. But from the other side, it's possible to disable tray icon. Here is a quote from the TridiaVNC change logs (in the beginning, TightVNC was based on TridiaVNC):

    - Added registry flag to cleanly disable the tray icon on all
    platforms and in all modes without affecting other settings.
    The default is "0" and indicates that the tray icon should not
    be disabled. A value of "1" will suppress the tray icon for
    all users.

    HKLM\SOFTWARE\ORL\WinVNC3\DisableTrayIcon DWORD "0"
    HKLM\SOFTWARE\ORL\WinVNC3\DisableTrayIcon DWORD "1"

      I too would like to keep TightVNC hiden form the users, I use it to keep an eye on the kids when they are on the net. I have changed the registry but this didn't work. My company uses TightVNC and they manage to run it in a 'stealth mode'. I know you dont recomend it but if the kids know im watching they will stop doing what ever it is they shouldn't be doing. Kind regards, and well done on a great application. J

          Well, being recently young and less recently a kid, I would inform you that the youngsters today know more than ever about computers, If they find out that your "spying" on them, and they will, you will lose their trust... My advice is more of passive monitoring, learn to check the logfiles (like history) and besides, the answer to your question is to basically to turn tightVNC into a backdoor/trojan, there are many programs which will do a much more effective job that already make my virus scanner light up like a christmas tree, I would hate it it that became the case with tightvnc.

    Another option is to use a file editing program to edit the icons embedded with the program and just make the connected and disconnected icons the same.

    There is an extremely inelegant solution to be had by editing the source code. While I don't remember exactly which file it is in at the moment, there is a line consisting of only AddTrayIcon(); which can be easiliy commented out.

    There is a project to implement configurable number of remembered connections (besides other great things):

    http://www.tightvnc.com/newviewer.html

    Actually, that has been implemented already, the only problem is that nobody wants to compensate the development efforts...

[»] remote upgrade

instead of requiring a reboot to install the new version, simply stop the server (stop the service or terminate the process), replace the files, then restart the server, before or after the user clicks on finish.

    I agree, this is the right way to upgrade running server, but the installer used in TightVNC (Inno Setup) does not allow to implement such scenario. It always copies files prior to executing any commands that could stop the server.

    The "Tight" encoding implemented in TightVNC combines both JPEG and PNG-like compression. Actually, the "Tight" encoding is even smarter than that, so a plain PNG implementation will actually descrease the performance.

      Hmm... really?
      Then May you envelope it into some graphic format to have tight-compressed images?

        Technically, it's not a problem, but I don't think that would make much sense -- software depends on the standards, and nobody will exchange images in a new format just because of better compression. Also, note that the algorithms used in the Tight encoding are more complex as compared to widely used formats. And another issue is that not all the pixel formats are used in the Tight encoding, only truecolor ones.
