Hi, I have spent two days searching the net but could not get my scenario work. Any help will be greatly appreciated. - I have vnc4 listening port 9000 on win2k - my dsl modem translates the port 21 to port 9000 on internal vnc server - when i telnet to port 21 on dsl modem i get the rfb message, so nat is working - when I run the viewer like mydslip::21 (vnc4 allows this) I get a connection reset by peer message. - When I put a secndary laptop to ibternal net and run vnc viewer there, it works fine.

TCP vs. UDP? Thus is the port you forward set up as a TCP port or maybe as a UDP port? Would swap your modem for something else, e.g. rule out the modem (or not ;-) ) as the source of the problem.

Re: vnc 4.0, NAT, connection reset
I would like to use port 9000 on the modem but I am also behind a NAT in the office and I am only allowed for ftp and http. I use http for my modem's remote mgmt and the ftp port is the only one left. In th emean time, what you suggest seems logical (i.e. modem's tracking of ftp flow.) I will check it also. thanks for the tip. sertar --- Rasjid Wilcox [EMAIL PROTECTED] wrote: On Friday 02 January 2004 20:04, Sertar Yalciner wrote: Hi, I have spent two days searching the net but could not get my scenario work.

Disabling Reg Key for DisableIcon
I have noticed that you have stated if you use the following reg key the tsr will not show using the following: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunWinVNC (REG_SZ) C:\Program Files\.\winvnc.exe -servicehelperThis works like a charm. I would like to go a couple of steps further. Are there reg settings so that this will run as a service but not show up in the services window? I propose the same question where the vnc.exe does not show up in the task manager? Has this been implemented and if so can you please let me know the reg keys to add. Simply setting: HKLM\SOFTWARE\ORL\winvnc3\defaultAllowShutdown (DWORD) to 0 does not do what I am actually asking. I have been able to stop the service using w2k when this value has been set to 0.

Re: failing to connect to server
David: Heya. It sounds as if your father-in-law is simply giving you the wrong IP address. That is, it's possible he's giving you the IP address that's valid on his network, which isn't the same thing as the IP address that the rest of the world sees him by. This process of IP address aliasing is called Network Address Translation or NAT. It can be done by his PC, his modem, or even by his ISP. To find out if NAT'ing is going on, have him open a web-browser on his VNC Server, point it to www.GoToMyVNC.com, and run the scan there. The easiest way to work around NAT'ing right now is to use the Add Client... option of a VNC Server. In this mode, the person on the *server side* tells the Server which Viewer to connect with; ie, your IP address. hope this helps, Scott I am an amateur user. I have used VNC very successfully to connect to my mother's Windows XP machine from my own W2000 PC (over a dial-up connection) in order to help her out with problems. I am now trying to do the same for my father-in-law, but am not succeeding and don't know why. He has opened WinVNC server on his machine, and has told me the IP address he gets when he hovers over the icon. I have entered this IP address in the new connection window of the listener on my PC. I am then getting a VNC Info message which says failed to connect to server. snip ___ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
Re: A question about using VNC over NAT
Howard: Heya. Here's a more recent discussion about VNC and NAT'ing firewall/routers like your DLink: http://faq.gotomyvnc.com/fom-serve/cache/133.html snip I have dug through the archives, but I must confess that I didn't understand a lot of what I saw there, especially concerning using VNC with NAT. The entries on NAT and VNC were all over a year old, too, so I'm hoping that there has been some additional progress made on that front. I have tried reading up on NAT, but I must confess that I didn't understand a lot of what I read on that subject, either. The work system is behind a firewall. My home computer is on a DLink 802.11b router, with an internal (192.168.0.x) address that can be either dynamically assigned by the router, or manually assigned on a router setup page. The DLink has a setup for something called a virtual server, with a list of internal IP addresses in the 192.168.0.x range next to dropdown boxes labelled service with the selections HTTP/SMTP/POP3/FTP/TELNET/IRC/ALL/NONE snip Some routers allow you to port-forward any port number you want; it sounds like your DLink is only allowing you to handle these 6 ports. Oh well. The easiest solution for you right now is to choose HTTP for your virtual service, and then setup your VNC Server to run on port 80 (instead of its default port 5900). Fortunately, this is very easy to do in version 4 of VNC. Once your server is running and listening to port-80, and your DLink is setup to port forward the external port-80 to your internal VNC Server, you should be able to connect with a VNC Viewer from the outside world. Just be sure to tell it to connect on port-80. Again, this is pretty easy to do in version 4 of the VNC Viewer. Hope this helps! cheers, Scott ___ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list

AllowShutdown will prevent non-Administrator users from shutting down the server. You must have been running as an Administrator when you tried it. There have been no legitimate reasons suggested for wanting to hide the tray icon under NT-based platforms, which is why it is not a feature.

VNC Viewer and PCAnywhere 10.5
I have found that after installing VNC Viewer, the TCP/IP Host mode in PCAnwhere 10.5 do longer functioned in my LAN. A remote trying to access the PCAnywhere host does not get a hookup screen. To correct it, I had to uninstall VNC viewer, uninstall and reinstall PCAnwhere. The ports used are not the same so I do not understand the reason why. The host uses windows 98SE and VNC viewer was installed to enable fast access to my office computer (VNC Host) over the internet with router and cable modem (wideband). VNC works quit well for that purpose but it does not seem to coexist well with PCAnywhere since I can't just stop the PCAnywhere Host when I want to use VNC Viewer and then end the viewer because PCA will no longer work until it is reinstalled. Any ideas? Is there a service that VNC Viewer starts that I have to manually stop with a ctrl-alt-del?? Any help would be appreciated.

Re: failing to connect to server
thanks very much to Scott Best, Dave Bricetti and ER Kooi, who all responded very quickly to my plea for assistance. The problem has now been resolved thanks to your kind help. The solution may be of help to others who are trying to connect to Windows XP remote PCs. The remote computer had its Windows XP firewall on. Unlike Zone Alarm etc, the firewall doesn't appear to be configurable to allow an incoming connection. The solution was to make the connection FROM the PC with the XP firewall, rather than TO it. This was done by having my father-in-law open VNC server app, right-click on the systray icon and select add new client. He then entered my IP address in the box , while I opened the VNC viewer in listen mode. As soon as he clicked OK on his add new client dialogue, we were connected, and his screen appeared on my computer. And his computer is still protected by the firewall. thanks again for all the help. regards David ___ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
RE: VNC Viewer and PCAnywhere 10.5
VNC Viewer is a mere stand-alone executable with some registry settings. In other words: it messes with nothing on the system.

using VNC behind multiple routers
I have VNC installed on my computer at home which is behind Linsys router/firewall. I need to connect one of my Stepfathers computers which is also behind a router/firewall. I do have SSH on my end but I don't think he has it on his. How should I go about making this connection? I can always send and have him set up SSH if it is necessary or recommended. ___ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
