Re: VNC Connection diffuciltiy
It sounds like the troublesome PC has XP firewall enabled (although it doesn't explain the unable to resolve host error). . Elminster wrote: Hi, After looking through the FAQs and searching the mailing list, I have encountereda puzzling problem. I have installed RealVNC on all of my Computers at home without any difficulty. I have now encountered my first. My latest computer on the network (a WinXP laptop) Is able to remote control every other PC on the network, but no other PC is able to remote control it. I have never had difficulty setting this up before, the basic automatic default install and config normally works. None of my other PCs have any difficulty with 2 way remote control. All devices are behind the same router, some are wireless and some are not, but for some reason this little baby won't play ball. I can ping it by name and IP Address, but I keep getting a timeout error or an unable to resolve host by name error, whenever I try to remote control the machine from a viewer elsewhere in the house. When I use the troublesome PC to remote control another PC it is fine. The only way I can get another PC to remote control the problem machine is by initiating the connection from "add client" which brings up the remote control window on the desired PC. Not sure what is going wrong here, or what I'm missing.

Zhang Wei, It sounds like you're using a VNC Free Edition viewer to try to connect to a VNC Enterprise Edition server that is configured with encryption always on.

Re: vnc connection to restricted XP accounts
I guess my question about workaround was related to running VNC as a service not a program. Can one workaround the Fast User Switching problem w/ VNC running as a service. Regarding alternative VNC servers I was thinking of open source options such as OpenVNC.

RE: vnc connection to restricted XP accounts
Paul, The workaround for VNC Free Edition is to log out the current user before logging on another one, so that the console session is always session zero. RealVNC is the company name and VNC the product, so I'm not sure what you mean by "Is the problem unique to RealVNC...". If you mean "Do VNC Enterprise & Personal Editions handle Fast User Switching?" then the answer is yes, they do!

Re: vnc connection to restricted XP accounts
I'll have to check. If this is the case, is there a work around? Is the problem unique to RealVNC or do other VNC servers have the same problem?

Re: VNC Connection Over SSH Problem
Here's the final solution to my VNC over SSH Problem (I use this to support my Father since he is just beginning to use a computer) On remote machine enter this command: ssh -l username -R:5900:localhost:5900:address.no-ip.com note: address.no-ip.com is my ip address assigned to a dynamic DNS service for the connection of the local viewing machine. On Viewing machine enter this command: ssh -p 5900 [EMAIL PROTECTED] note: The cursor will hang but is connected; ctr+c will abort the connection if you wish On viewing machine enter this command in new terminal: vncviwer localhost::5900 Ideally to spead things up, create icons on the two computers desktops to facilitate a connection. Here are the steps: To Setup quick lauch on remote computers desktop (GNome Desktop) 1. Rt click desk top and create launcher 2. for command use: xterm -e "ssh -l username -R:5900:localhost:5900:my-address.no-ip.com" To setup quick launch on viewer (GNome Desktop) 1. Rt click desktop and create laucher 2. for command use: xterm -e "ssh -p 5900 [EMAIL PROTECTED]" 3. Rt click desktop and create launcher 4. for command use: xterm -e "vncviwer localhost::5900" Of course, before initiating an SSH connection, I copied (SCP) a SSH public DSA key from the the remote to the viewer computer (there are plenty of instructions online already for setting up SSH keys so I won't rehash.) I used a blank passphrase for the remote computer to make it easier when connecting and supporting that all important friend or family member. I know this isn't the best security model, but it works for what I needed to accomplish (making it simple for humans w/o computer skills:) ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list

RE: VNC connection problem
SL, If you have simply installed VNC and allowed it to register the VNC Server as normal, and not changed the service's startup settings, then it should work as expected. Which version of VNC Server are you using? What is the error you get when you "can't connect"?

Re: VNC connection closed w/ error 10055
ZoneAlarm was completely removed (no change in behavior) Also to confirm, RealVNC was running as a service and no screen saver enabled. RealVNC seems to have had no issues interacting with desktop. Client functioned perfectly for a short period of time (1-5 minutes). Longer, if I didn't actually do anything on the remote machine and just let the connection sit idle. Also, a number of other things were tried. Final resolution: I ended up uninstalling RealVNC and installing TightVNC. Was able to connect from Win XP systems and remote control Win 2000 system with no issues. So, it looke like TightVNC will be my solution. Thanks to everyone for all the suggestions and assistance.

Re: VNC connection closed w/ error 10055
James, When i run a netstat -an on the client I get 7 "established" connections. one of which is vnc: TCP :3307 :5900 ESTABLISHED netstat -an on the vnc server machine gives me 3 "established" connections with one vnc: TCP :5900 :3307 ESTABLISHED Hard to believe that 7 and 3 established connections respectively, could cause memory allocation or resource management problems. As far as firewalls are concerned, I have the Zone Labs firewall installed, but have it disabled so as not to interfere with VNC. In addition, virus scans show my system to be clean. Once again, Thanks for any input.

RE: VNC connection closed w/ error 10055
Collier, Error 10055 normally means that there are too many connections open on either the server or viewer machine, meaning that the OS can't allocate enough memory to manage them all. Try running netstat -an on both the server and viewer when you see this error & check how many "established" connections there are to other systems. According to a quick Google search, there are some viruses that can cause this error to appear, a Windows 95 resource leak that can, and it's also possible that third-party firewalling software might cause similar issues if it has memory leaks, or if it exposes bugs in the OS Regards, Wez @ RealVNC Ltd. > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Collier Hill > Sent: 27 September 2005 21:07 > To: vnc-list@realvnc.com > Subject: VNC connection closed w/ error 10055 > > I have seen a couple of references to this issue in previous > posts, but see > no resolution posted.

Two things: Do you have the XP firewall enabled? If so, try disabling it. Also, have you tried specifically allowing the VNC executeable in the firewall, even if disabled? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Collier Hill Sent: Tuesday, September 27, 2005 4:07 PM To: vnc-list@realvnc.com Subject: VNC connection closed w/ error 10055 I have seen a couple of references to this issue in previous posts, but see no resolution posted. So, here is my problem. configuration: VNC Server 4.1.1 for Windows on Windows 2000 Pro VNC Client 4.1.1 for Windows on Windows XP Pro I start the VNC client on XP and successfully authenticate and connect to the VNC server. The connection seems to function properly for 1 - 5 minutes. Then the connection is automatically closed with the following error message: VNC Viewer : Question Unable to wait for socket data: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.

Re: VNC connection lost when initiating telnet session quits
Hi Iam using Fedora Core 1 with tight vnc. When i try nohup vncserver &, it seems to work fine. That is, i log in using ssh and start the vncserver (nohup vncserver &)in my remote comp and close the ssh. Now i login using the windows vnc-client and now iam able to view the gnome desktop as well as my apps (i.e windows manager is working). Probably in Solaris, nohup does not insulate the process from the SIGTERM signal. If that is the case why is the Xvnc not killed and only windows manager refuses to start. Any light on this?

Re: VNC connection lost when initiating telnet session quits
I already tried that. Still have same problem when log out occurs...apps die . Even tried "nohup" inside xstartup file in front of xterm, vncconfig lines to see if that made a difference.it did not. In Solaris, nohup does not insulate the command from the SIGTERM /usr/bin/nohup Processes run by /usr/bin/nohup are immune to SIGHUP (hangup) and SIGQUIT (quit) signals. The nohup utility does not arrange to make processes immune to a SIGTERM (terminate) signal Now whether that is pointing to the cause or not is anyone's guess.. On Apr 29, 2005, at 4:59 PM, B.

Re: VNC connection lost when initiating telnet session quits
Try preceding the command with "nohup". For example, "nohup vncserver :1" Then it should be unaffected when you log out.

SO, a couple things to try: When at home (the server end): go to http://www.canyouseeme.org/ and scan for 5900 If this says closed, then it is being blocked at your router or your pc. First make sure the router has a port forward set-up Second double check the xp firewall third if you are running any type of antivirus shut it completely down, along with any other "security" tools you have. As you perform these steps keep checking the status of 5900 from the web page. At some point you will find your culprit.

Re: VNC connection through VPN and wireless problem
Greg: Heya. Sorry for the late reply. Here's another possibility: different Ethernet NIC's can come with different MTU sizes. Due to the IPSEC wrapping of your packets in a VPN, an otherwise functional MTU size can be exceeded, and packets get fragmented leading to uncertain behavior in VPN settings. Which is all to say...try reducing the MTU size on your wireless NIC to that if your wired NIC and see if it helps.

Re: VNC Connection via HotSpots with McAfee Firewall
You could open the port completely, and trust VNC and a very,very,very good password. Or, you could configure a SSH server on your network and connect with the tunnel (with port forwarding). It would provide encryption and another set of passwords for connection. The other option is to replace the router with a full linux/bsd firewall where you can selectively open ports. And not the crude functionality of most commercial software firewalls or basic routers. Also, it can be the SSH server, so you could use the SSH port forwarding. These are summary solutions, if any sound interesting I can go into more detail. Joe Kexel >Jonathan C. Miller said: > I am running RealVNC behind a router with forwarding setup on Ports 5800-5900.

On the other side, the browser is only a single binary that does not need any customization. Just dump it somewhere (in the path, like /usr/local/bin/vncviewer), give it execute rights and `vncviewer myhost:6` boosts you away.

Thanks for the reply William. I've tried to connect to http://myhost:5806 and after about a minute I get an error message about "Cannot find server". To avoid issues with the DNS I've also used the URL in the connection to the host like http://123.456.789.0:5806 with no success. I have a web server running om myhost and I can connect to http://myhost:80 with no problems. Again if I connect to http://myhost:5906, at least it respond back with 'RFB 003.003'.

RE: vnc connection forwarded problem
Hello, Mauricio. I suppose the vncserver on your home win98 runs on the default port. You should login with the f-secure client from win98_work to the linux and forward local port 5901 to win98:5900 and local port 5801 to win98:5800. I do not have f-secure here, but in the Unix ssh jargoon this would be like "ssh -L5901:win98:5900 -L5801:win98:5800 linux". You need to translate the "-L5901:win98:5900 -L5801:win98:5800" to the f-secure settings on win98_work.

Re: [VNC] connection closed
Most likely, this is an issue with how password setup is done in VNC. Here's a way to make sure that the password configuration is done correctly. The following method was actually a recipe that Floyd Russell developed for making sure that VNC runs correctly on Win2K servers with Terminal Services; in general, it seems to be the best method to use with NT 4, Win2K, XP, and .NET in any flavor. To my knowledge, it has always made this work correctly if done with a clean install of VNC. "1. Install VNC 2. Install VNC Service 3. Start->Programs->VNC->Run WinVNC(AppMode) 4. Enter your password, this is for the current user. 5. Start->Programs->VNC->Administrative Tools->Show Default Settings 6. Enter your password, this is for the local machine 7. Close WinVNC 8. Start WinVNC Service You may need to start the service helper if you want to modify settings of the winvnc instance running. This problem is due to the way Terminal Services operates, since you are working in a virtual desktop." - Original Message - From: "Jozef Leeuwen" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED];[EMAIL PROTECTED];;;> Sent: Sunday, 2002-05-26 12:26 Subject: [VNC] connection closed > Hi, I've installed VNC 3.3.3 installed on an HP Netserver LH Pro with 32MB RAM and W2K professional, 800x600, 16 colours. > > Any time I want to connect from a client (windows), it will ask for the password, and then send me a 'VNC info' window with the text 'connection closed'. > > I've got no clue on what could be the problem.
