Fix your mom’s computer with UltraVNC
Posted by Andy Atkinson on 11/2/05 in Freeware, Software, Tutorials
While visiting home I realized that I didn’t have a way to connect to my mom’s computer when she needed help. In a previous article I experimented with Window’s Remote Desktop and Remote Assistance, but found that is was not quite right for what I wanted to do. If your mom is on Windows XP and having a computer problem, UltraVNC is an amazingly simple way to remotely administer her PC and fix problems while she is still logged-in. Unlike RD where only one active user can be logged-in at a time, UltraVNC (a.k.a. Ultr@VNC) is designed to make it easy to gain mouse and keyboard control of a remote PC while the local user is still logged-in. Ultr@VNC is also secure since the server PC only needs to run the server software when they need assistance. As the client computer, you don’t need any client software to connect to the remote computer as you can do this through any Java-enabled web browser. This means I can remotely administer my mom’s computer from any type of machine (x86, Apple, Sun).
Port Forwarding
In the screenshots below you will see me logging-on to my mom’s computer using Safari on OS X. In order to connect to a remote computer that is behind a router and firewall, you will need to permit access on certain ports, commonly called “Port Forwarding.” The default port for Ultr@VNC when you are connecting to a server with client software is 5900. If you are connecting to an Ultr@VNC server from a web browser, you will need to open port 5800 on your router or on your personal firewall software. If you chose to install Ultr@VNC as a service (which I recommend), then the built-in Windows XP firewall (if enabled) will automatically open up the appropriate ports for you. Remember that if you are running Ultr@VNC with a third-party software firewall OR if you have changed the default ports, you will need to forward the correct ports on your router and firewall.
Using the Ultr@VNC server software you can define a password that the connecting-user will need to enter when they connect to your server. This way my mom can define a new password each time I connect to her machine, adding to the security of this approach to remote administration.
Ultr@VNC gives you a number of useful options like “file transfer” in an unobtrusive bar located at the top of the screen. Once you are connected to the server, this bar will appear. Some of these additional features help differentiate Ultr@VNC from other VNC-variants.
In the screenshot below you can see that I am connected to my mom’s computer and running paint. Even with my mom connected to our own cable internet over wireless (802.11b) and me “borrowing” my neighbor’s unencrypted wireless (802.11b), the speed was very acceptable and as fast as anything I have ever used over a LAN or a WAN.
As soon as you log-in Ultr@VNC is setup to remove desktop wallpapers and other GUI effects without interrupting the current user and without losing any functionality. When you log-out or simply close your browser, it immediately restores wallpapers, drop shadows, and other graphical extras to the local user. The whole experience feels snappy, even on older PC hardware and with the latency of an 802.11b wireless network. This setup is also secure because the user requiring assistance can run the Ultr@VNC server only when they need help. All my mom needs to do is report the IP to me that whatismyip.org gives her (she has a dynamic IP address and I have not setup a domain name for her PC) and to double-click the Ultr@VNC server icon on the desktop. When I’ve finished helping her, she can close the server. Ultr@VNC is also very convenient because I know I will always be able to connect to my mom’s computer regardless of what computer I am running. Every operating system out there is capable of running a Java-enabled browser, and most come with one by default.
I had a completely “stock” install on my mom’s machine, note the permission of HTTP connection requests and that a password has been setup.
Another VNC-variant worth mentioning is TightVNC. Like Ultr@VNC, TightVNC has a Java viewer that you can use in place of a client application. According to the reviews I read, Ultr@VNC has more features than other VNC-variants like TridiaVNC or TightVNC, which put it in front.
11/08/2005 Update: My mom was complaining that she was being prompted to enter a password when she logged-in to Windows. When I logged-in to her machine I realized the UltraVNC server was running on startup as a Windows service. I wanted to prevent this from happening so the server ran ONLY when my mom double-clicked the icon.
To do this you can hit Start > Run, then type services.msc to bring up Windows Services. Scroll down to VNC Server and under the “Startup type:” drop-down menu choose Disable. After you press ‘OK’ and reboot, you should not see a VNC server icon in the system try at startup. This way my mom won’t be bothered by any VNC-related pop-up boxes in the future and her computer won’t be open to any unknown VNC connections.

Nice articles Andy, this will come in handy when I have to do the same thing for my parents. Also, I was trying to do a similar thing last year and learned that you can have more then one person logged in at a time on a Windows XP machine, but it requires some registry hacking - UltraVNC looks like a much safer approach.

Hello,
This is a nice and useful article. I have a question though that I could not find an answer for.
My father is behind a firewall at his company and their administrators won’t open any port so I can connect to his computer.
I figured that if somehow his computer initiated the connection to my computer than I will be able to control his computer. But I have not seen any tool that does this reverse connection. Are there any solutions to this?

Hello,
There is a patch available in order to allow concurrent connections on Windows XP with Remote Desktop. Although is does not allow the user logged in locally to see the other user’s screen, it still gives a lot more flexibility. Look for something like ‘teminal services windows xp patch’ on Google. I still find Remote Desktop much faster than VNC, and no install/configuration is necessary. And there are ports of the Rdesktop client for almost all OS that I know of as well (Linux, BSD, OSX…).

Used this very successfully with my Mother in Law.
I went one step further and generated a SINGLE CLICK installer preloaded with my IP address that she could just double click and back connect the the UVNC Viewer I had running. No need for her to find an IP addresses or do anything but launch a small program.
Check out the SINGLE CLICK Packager:
http://www.uvnc.com/addons/singleclick.html
A little less secure, but for a short fix it up session it was the best option going. My IP stays pretty much the same thanks to my router, so the SINGLE CLICK package on her desktop stays good. If my IP changes, I just generate a new one and email it to her or put it up on a webpage, send the URL and tell her to RUN PROGRAM FROM HERE and it connects up just fine!

Great article - but it is certainly worth mentioning that use of the DS encryption plug-in provides decent protection for both the password handshake and the session.

But i think this should work on any OS because its java based.

Great write up! Question though. I am a teacher and all my students have computers, and at times, I would like to take control of their machines. To demand their attention, show how to work an app, knock them off the internet or email (novell) when they shouldn’t be on it. All with a single click. I have about 25 desktops I want to control. Can the Ultr@VNC achieve this for me? Thanks!

Remote Support System.
http://www.download.com/Remote-Support-System/3000-7240_4-10447877.html
Great tool. Takes about 2 minutes to create the exe file. Then send it to your friends and family run the server on your end and bam instant connection.
This software package will allow you to create a single exe file that a client can download off your Web page. When executed it will automatically connect back to you (through firewalls) and allow you to provide remote support. You now can provide support for clients you’ve never even met, transfer files and directories, chat with the client, reboot the remote PC with auto-reconnect, reboot the remote PC into safe mode with auto-reconnect. A customizable invoice for the session is generated automatically. The program is free for non-commercial use only. New in version 1.5.1 is the ability to draw on remote client’s screen, and a pager / attention bell to get their attention when needed.

Anybody know of the way to access VNC through port 80? fyi, my company block all the port except 80 and https port.
Chui Tey | Nov 5, 2005 | Reply
RealVNC viewer has a listener mode. The VNC server initiates a connection to the listener. Here’s a sample batch file for your mom, with a few more tweaks, it can go out on port 80, by default it is 5500:
start /MIN winvnc4.exe PAUSE Hit Enter when you see VNC in the lower right corner winvnc4.exe -connect “vnc-client-ip-address”

Thanks for your helpful article. Is this technology available for other verisons of Windows? I believe my mother-in-law has Wiindows Millenium.
Thanks, Chris

The SINGLE CLICK package is the way to go. I created one that connects back to my IP and then installed it on the computers of everyone in the family. It makes it a piece of cake when they need help - they call me, and I have them click on the icon to share a desktop.
Andy Atkinson | Nov 6, 2005 | Reply
Hello John, thanks for the compliment. As other visitors have pointed out, there is another version of UltraVNC called UltraVNC SC that lets users initiate connection requests outward. I haven’t played with this yet, but since the user initiating the connection needs to traverse the firewall to make the outside connection, it makes sense that the remote user would be able to connect by following the reverse path.
UltraVNC SC

Hello Chris. Yes, UltraVNC says on their main page that it runs under Windows 95, 98, Me, NT4, 2000, XP, 2003.

Thank you for your suggestions. UltraVNC Viewer (in listen mode) does the reverse connection that I was looking for. The only problem is that my father’s company firewall blocks all non-http traffic (I set VNCViewer to listen on port 80 but it didn’t work, as the firewall stopped the non-http traffic).
Is there a way to make UltraVNC (or another program) use http requests for the transfer? (Just like Yahoo Messenger’s option “Firewall with no proxies”)
Thanks

Hey, I did some research into Dexter’s post above and found a very cool hack out there. It allows you to run your XP box as a full terminal server so you can have multiple simultaneous connections as well as shadow a session.
While I might still use Single Click VNC for support, Terminal Services is great where you need to connect to a computer even if there is someone working on it.
Here is the link: http://sig9.com/articles/concurrent-remote-desktop
Again, I have done it and it works great.

I work in the IT department of a large company, and if I caught an employee trying to compromise our firewall like that, they would be in hot water.
Seriously, your dad most likely would have signed an acceptable use policy for company computing equipment when he started working there that prohibits just this kind of thing.

Ultravnc does not work through private networks, NAT and firewalls. RemotePC (http://www.remotepc.com) is a great way to connect to anyone’s PC, especially if the host computer is behind a NAT. I think remotepc is the best remote access solution.

You can either download the client application, or use the web browser. Make sure you have your firewall configured correctly or temporarily disabled. If you want to use a web browser, make sure it has Java installed (it will prompt you if it doesn’t). Then figure out what the external, routable IP of the machine is you want to connect to (use “http://whatismyip.org” or another method), and type it into the web browser. Example: http://66.67.68.69:5800. The “5800″ is the port on which the UltraVNC server is running, you will need to specify it with a colon. Hope that helps.

I happened on this discussion after googling for UltraVNC. And I have to say I am lucky as I seldom have to deal with imbeciles that are trying to circumvent network security. I can’t think of ANY reason an employee’s offspring should EVER be remoting into a network I manage.
Andy Atkinson | Dec 8, 2005 | Reply
Thanks Sean. I wanted to explore methods of remote connectivity through firewalls, but I certainly don’t think anyone should be remotely connecting inside a private LAN environment. What I want to explore is more about helping out family memebers in their own home, but thanks for drawing attention to the fact that en employee would certainly be violating their license agreement by having a unauthorized user log-in remotely to a PC.

I have winvnc on win2k servers with fixed IP addresses. From behind my work firewall, using a browser and port 5800 I get the login screen. Thats great, but when I submit the password I get the error “java.net.UnknownHostException:“
Any Ideas? I’ve seen posts about something called SCIII that may work and downloaded it but it seems to do nothing - or I’m just not seeing it.
Andy Atkinson | Dec 19, 2005 | Reply
Not entirely sure, but I know I get a similar error when the VNC service is not running. I don’t have it set to run automatically when Windows starts, so sometimes I forget to start it. On Windows XP, you can go to Start > Run > type ’services.msc’ and scroll down to the “VNC Server” service, right-click it and hit properties. Make sure it is started. Not sure how this maps to Windows 2000. I also noticed that I had to open up port 5900 and port 5800 since VNC runs on 5900 (these are defaults) but accepts HTTP requests from port 5800. Hope that helps.

Hey Andy, Great job on the site, I really enjoy it. I was wondering if you know how many concurrent Uvnc connections you can have. I need to be able to load Uvnc on my windows 2003 server and have multiple concurrent connections logged on to it. Do you know if this is possible?
Thanks in advance for your insight.
Andy Atkinson | Jan 17, 2006 | Reply
Hi Tim, thanks for the compliment. I did a little bit of searching, and it looks like you can download this “Repeater” add-on for Ultra VNC that supports concurrent users. This forum post seems to say that there are 20 “slots” listening for connections when you are running the repeater. Would that suffice for what you are trying to accomplish? Do you need to support more than 20 simultaneous connections? This might be worth looking into myself. I’ve found the documentation of UVNC to be rather poor, so I’d like to contribute by testing things that might be of use to other people and myself. I know Windows 2003 will give you concurrent users (without blanking the local screen) out of the box. The limit is probably defined in with a registry key and largely depends on system resources? Does Remote Desktop Connection suit your needs?
Tim | Jan 18, 2006 | Reply
RDC is excatly what I would like to use, however… 2003 server will only support 2 concurrent connections via RDC without purchasing additional licenses. The additional licenses are around 2000 each for this type of connection. I would really like to spare that kind of expense if it is at all possible! All I really need is the ability for 4 users to concurrently connect to the server. Unfortunately, I am only able to connect 2 at the same time using RDC.
Thanks again Andy

Andy Atkinson | Jan 24, 2006 | Reply
The idea was that this was supposed to get you up and running, but the article could be improved. It’s difficult to write for different technical expertise levels however, without knowing ahead of time who will read the document.
If you are looking for a very easy way to be able to access your remote machine, I suggest creating a free account with LogMeIn, if you found this tutorial too difficult. Generally freeware or open source software requires a heavy amount of “configuration,” which is good and bad depending on your skillset and the amount of effort you want to expend.

Y’know, Andy, I think what we got here… is a failure to communicate.
(Did y’see Cool Hand Luke, dude? GREAT movie. Old, maybe - but GREAT.)
Anyway - I need to ask you the same question 11 other good folks here have just asked you. HOW DO WE SET UP AND USE SINGLE CLICK UNTRAVNC?
Please don’t tell us that just because we had to ask for help that we don’t deserve the help. And PLEASE - don’t tell us to start using LOGmeIN. As far as I’m concerned THAT is not an answer. That’s an insult. We all came here for the same reason - help learning and implementing SC UltraVNC - not to be driven away by somebody with an agenda.
Thanks. If you can’t tell us how or for some other reason don’t want to provide the steps then is there anybody else that would be kind enough to walk us through it?

This article is for “UltraVNC.” The single-click add-on (SC for short), was an afterthought, and is mentioned in another article. I planned a follow-up article on SC specifically, installed it, tried to get it working between two PCs, but ran into problems. I found the documentation to be terrible, and didn’t spend much time troubleshooting. I also did not have convenient access to two PC’s at the time, and now I do. I’m sorry you found this article to be of no value, I’ll definitely take your suggestion for a step-by-step guide on implementing SC. Please send a mail to paininthetech@gmail.com, and I’ll be sure to ping you back when I complete the article.

This isn’t going to work the way you want it to - your helpdesk.txt file is using private IPs inside your company LAN, which your remote users won’t be able to resolve.
In order to do what you want to do, you’d have to get TCP ports punched through your company’s firewall to each of the above analysts, and set up [HOST] entries in your helpdesk.txt to look something like this:
[HOST] AUTRY-BRYAN -connect my.companys.public.ip:5500 -noregistry
[HOST] HALE-KELLY -connect my.companys.public.ip:5501 -noregistry
[HOST] NORTON-ANN -connect my.companys.public.ip:5502 -noregistry
Note that you have to use an IP ADDRESS, not a domain name, in those [HOST] entries - the singleclick client won’t resolve DNS stuff. Also note that you’ll either have to set the VNC Listening Daemon on each of the computers to listen on the same port you set up in the file, or (recommended, if your router will do it) set your router to forward from port 5501 to HALE-KELLY’s internal IP address on port 5500.
Once you get these entries fixed with the proper data, you - annoyingly enough - have to upload your fixed-up custom.zip back to the ultraVNC SC web site’s “Creator Tool”, currently at http://sc.uvnc.com/index.php?section=19, where it will unpack your zip file, pack all the contents into an SC file it will call “custom.exe”, and offer that file back to you for download.

Hello, I installed the product on 2 pc’s running xp. I run the server on one pc and the viewer on the other. When I attempt to connect, Norton asks me if I permit the connection (I reply yes). After I reply yes it states connecting…. and then fails with “failed to connect to server!”. I tried it with Norton down and got the same thing. Can anyone shine some light on this problem. thx in advance..
Andy Atkinson | Jul 28, 2006 | Reply
Hello Fernando. Are you aware that Windows, as of Service Pack 2, has a firewall that will block inbound requests to certain ports (but not outbound)? So on the server machine, you can either disable the Windows firewall, or manually add an exception to the firewall. The exception you will add is the port the server is running on. This Pain in the Tech article covers how to add an exception to your Windows firewall settings. Post your results if you still have problems or are successful. Thanks.

Hi All,
I’m trying to get Ultra VNC SingleClick to work!
Do I have to manually type in an IP address, or can I use No-IP.com
Unfortuntately, my ADSL connection does not support a static IP address.
If No-IP doesn’t work, can anyone else suggest another service that will?
Also, on what do I need to do on my computer to enable it to ‘answer’ any requests from my mums computer.
Thanks!

VNC SC works great and i use it with several friends i support remotely. Unfortunatly most ISPs use dynamic IPs that change frequently. The answer is to get a free acct at dyndns.org. Your IP will automatically be registered on the service and you can then provide your users with a static name that can be kept in the .exe file you give them. You can have your router automatically update dyndns or do it manually when they email you a note.
On your end you will only need to start VNC View (listen Mode) when someone needs help.
The only thing you will need to do is probably zip the .exe file as most email programs will strip them out to protect the users.
Good luck.

Thanks Andy for this forum. Hope you can help me. 3 issues:
I have java installed. I’m running I.E. 7, and FireFox; XP SP2,
When some are accessing the server I want the screen to come up at 85% so that it doesn’t take up all of their screen and can show the server task bar. I know that each user can adjust this themselves via the tool bar at the top; however, this is a group of newbies.
I would love to be able to show them share my desktop/presentation when I’m on the road via my laptop. I’d also like for one of them to do with the group without them having to no what port forwarding is, let alone try to implement it. Is there a solution with the ease of single click that can allow many to see my or their laptops/presentations when not on my server which does have port forwarding configured already?
Tom | Nov 28, 2006 | Reply
I’m confused. Jim Salter on 5/20 says you must use an IP address not a domain name in the entry of the Helpdesk file since SC wont resolve DNS. Later, Eli, on 10/28 suggests you can use a static name provided by DynDNS, (and I’m assuming No-IP). Which is correct, only IP or will either work?
Thanks

Hi all.
I seem to be having a problem getting VNC SC to work. I have created an exe and done everything right (As far as I know) but when I double click on the exe that I created it goes into “listen mode” which means I end up with the viewer in listen mode and the sc in listen mode. Any help would be appreciated.

SC definitely does work with no-ip.com or any other dynamic dns, as well as standard domain names. It WILL resolve DNS. I write custom software for a living and use single click for tech support wherever I can. Unfortunately, I have not yet found a way to get a user connected to my viewer when they are behind a firewall that doesn’t allow connection on ports other than 80 and 21. I was starting to write up the procedures to get this set up, when i found this link:
http://www.uvnc.com/man/sc_stepbystep.html
Whoever typed this has some problems with their English, but everything is there. It’s really simple once you get the files and look at helpdesk.txt
I can’t believe there are people out there who actually like webex. Maybe it is because it is overly user friendly. It is very impractical for any kind of tech support as there are way to many step between the user saying they need help and you getting control of their desktop. That’s not to mention the fact that it is incredibly slow, and it doesn’t work properly if one end is using the ActiveX control and the other is using Java.
Anyway… I hope this information helps.

I was reading about running realvnc on windows xp on a domain. I have configured the port forwarding and tcp ports for the computers on my router. The win 2000 computers work fine but not the win xp. Is there something I am missing? Is there something I have done wrong? Or can I not run realvnc server on a win xp domain?
Thanks Jane

While trying to use logmein from remote pc there is 50% occurance when I get message:”failed to connect through socket and trying http tunnelling” sometimes is works through. For my host PC I am using linksys router where I share DSL connection with others. Please advise how can I resolve this problem for 100% guaranteed connection without failing. Tell me if it requires port forwarding with some advise as to how to implement it.
Thank you

Listening mode, for those who don’t know, and I have just found out, is activated from the Start> AllPrograms> Ultr@VNC> Viewer in ListenMode. This wan’t and isn’t made clear.
Now, back to my many questions since I’ve not given-up just yet. I’ve been working on this all weekend and today and still haven’t been able to get this thing going - Don’t get me wrong Ultr@VNC Rules.
I have so far done the following:
on the helpdesk.txt I have: [HOST] Double-click here to connect -connect 192.168.0.1 subdomain.serveftp.org:5500 -noregistry or should it be [HOST] Double-click here to connect -connect subdomain.serveftp.org:5500 -noregistry or should it be [HOST] Double-click here to connect -connect 192.168.0.1:5500 -noregistry
When the client executes helpdesk.exe it open fine and goes into listen mode ***Why do I have to pieces in listening mode - the client side and the support side?????
Now for the router
As you can see the IP for the router is the default 192.168.0.1 BUT you have to remember that I have three machines behind the router and I want to use 192.168.0.102
PortForwarding has been enabled as instructed and http://www.jointcomms.com/pirc/ultra02.gif
DDNS set up according to instructions and the subdomain I acquired from dyndns. http://www.jointcomms.com/pirc/ultra01.gif
What am I doing wrong? There’s gotta be SOMEONE here who knows what I’m doing wrong.
Thanks

Is there something I am missing?
It is easy to forget about the Windows XP fire wall. It will block VNC (and ultraVNC) connections. The easy way to fix this without turning off the fire wall is to goto Start/Settings/Control Panel/Windows Firewall then select the Exceptions tab. Use the Add Program button to select UltraVNC. If you then use the Change Scope button you can put limits on who is allowed to connect to VNC.

Hi I was wondering if you can tell me how I get the option to “Share only the server window named” to work in Ultravnc? I need to have it so that a user can access an application running on the desktop of a NT Server but not allow this user to go beyond the application or desktop itself.
Thanks for your help
