I am using Windows Authentication to authenticate clients from other Windows XP Pro client machines. This morning the server ceased to accept connections from any of my client machines, the client machine receiving "An authentication error occurred. See the server error log for details. Do you wish to reconnect?" I can find no such error log, there are no errors in the windows event log in either the client, server or domain controller machines. If I disable windows authentication clients can connect. The effected server machine can connect to other VNC servers on the network (also using windows authentication) as a viewer. What would cause VNC to stop working in this way?

The developers of TightVNC have told me that their dist will not run as a system service on Windows Vista in it's current incarnation. Since I had the same problem with realVNC, I suspect it's the same case here. TightVNC has an upcoming new release that will supposedly work on Windows Vista in system service mode. In any case, the workaround is to run the VNC server as a user application instead of a system service - you should be able to get a connection then.

I've run a vnc-server on hp-ux in the past century. In the 1990's, I used the binary Xvnc for/on hp-ux. You should be able to find a hpux package for free. There are several ways to setup vnc on unix machines. The vnc package for unix contains a binary Xvnc, which can be used as a replacement or additional X11 server. There are various recipies in the archives of internet, even in the archives of this maillist, if they go back that long. If you are desperate and I can find the time and the data, I might dig it from my memory. Unfortunately, there are no hp-ux machines around to fetch the working settings.

A win xp machine and a mac book pro. Both systems have vnc enterprise servers and viewers version 4.5.x installed with the servers configured to operate in service mode. When I use the mac vnc viewer app to access the windows machine vnc server and thus remotely control the windows machine, the speed is incredible, like sitting at the actual windows computer. When I use the windows vnc viewer to access the mac vnc server and thus remotely control the mac, the speed is horrible, about 1/4th the speed of the aforementioned scenario. When moving a window or scrolling a page, I can count to "2" (so about 1 to 2 seconds lag) before the scrolled page or moved window updates on the vnc viewer window. Clicking pull down menus at the top of the screen takes several moments for them to appear in the viewer. I have the mac machine (running the vnc server) sitting next to me to test this while I access from the windows vnc viewer, and the screen updates are obviously instantaneous on the actual mac. So the lag is in the vnc connection itself. On both systems, I have the viewers set to 'adapt to network speed'. Even going manual and sliding the slider to 'most compression' does not work. In fact, while reducing the colors and making things hard to read, it actually seems to make the mac vnc server even slower to respond. What should I check or adjust to help increase the performance of the mac vnc server, as this level of performance is nearly unusable..... Thanks!

That's the one that captures the screen and sends it over to the viewer. For msWindows, there is only one way to act as a vnc-server: replicating the session at the console. Hence it is optimized to do so. In the old days, it was just capturing (polling) the display memory. With curent vnc-servers, hooks are used to effectively capture only changed parts. At the server side, there are some options to tune and tweak this. For unix there is a complete different approach: From the start (way back in the '80s or early '90s) the vnc-server provides a new session, complete independent from the console session. Only after the msWindows implementation shows the console and unix became in use at the console, this became wanted in the unix implementation. Since the unix console is constructed in several layers, there are multiple aproaches to capture the console: Low level aproach: vnc-console-server captures the display memory: This vnc-server is hooked to the X11 server, the display driver on unix machines. Most implementation binaries start with a capital X. The origional vnc-server reflects this by being called Xvnc. On linux this is a module that can be loaded in the X11 environment and is configured in the /etc/X11/xorg.conf file or around. The middle level aproach: vnc-console-server hooked into the window manager: The window manager is the tool that effectively puts the windows on the screen. These binaries most times end their name with 'wm'. Old/antique names include sunwm, xwm, cdwm, kwm and such. As far as I know, the kwm (from the kde-bundle) does have hooks/libraries/modules to act as a vnc-server. The top level aproach: vnc-console-server hooked into the display manager. This is the tool that hanldes the menus and such on your system. I donnot know vnc-server implementations by head. I'm sorry I donnot know what is available on apple, All I do know, it is a unix implementation, hence, it uses one of the unix aproaches. I'm not sure if you do have a choice on apple. All I do know is the more low-level the vnc-server hooks into the system, the faster it is.

All I can see, that a black DOS command line window pops up for a millisecond in the left upper corner of the screen, but nothing else happens. The same computer has no problem connecting to the listening viewer by having the user typing (copy/pasting) the IP address of the viewer in the window. (The port 5500 on the firewall of the listening viewer is forwarded to the listening computer (otherwise the manual method wouldn't work either, right?) This is the command line that I think should work, but it doesn't: (IP address here is a bogus one, of course) "C:\Program Files\RealVNC\VNC4\winvnc4.exe" -connect 99.999.999.99:5500 Any idea why this command line doesn't work but manually the PC can connect to the listening viewer without any problem?

I've got my VNC server running on a CEntOS 5.4 box. If I just enter the IP address & firewall port (i.e. 10.16.0.136:7) I can connect fine using Real VNC's "VNC Viewer Enterprise Edition" version E4.5.2 client software from my Mac (OS X 10.5.8), or using the "VNC Viewer Free Edition" version 4.1.2 on my PC (XP). However, problems arise when I try to initiate a connection over SSH (i.e. 10.16.0.136 localhost:7). On the PC, it seems to work fine -- although, is there a way to verify that the connection is indeed over SSH? The connection info panel doesn't seem to indicate either way. On the Mac, when I try to connect over SSH, I get this error: "getaddrinfo: nodename nor servname provided, or not known (8)" A Google search turned up articles pointing to Apple's implementation of OpenSSL.

I tried it with :5500, ::5500 and without any port designation. I am doing these tests on my home network with two computers, both of them have XP Pro sp3. BUT THE MOST IMPORTANT FACT IS THAT THERE IS NO PROBLEM CONNECTING TO THE LISTENING VIEWER COMPUTER BY RIGHT CLICKING ON THE VNC SERVER ICON IN THE SYSTEM TRAY AND ADDING THE IP ADDRESS TO THE DIALOG WINDOW "Connect to listening VNC Viewer". I also tried to connect to the listening computer using telnet, the connection was successful. So, the bottom line is, that using the GUI interface there is no problem at all, using the command line interface it gives the error message "Unable to locate existing VNC Server". "C:\Program Files\RealVNC\VNC4\winvnc4.exe" -connect computer2 I think either I am not using the correct syntax or RealVNC has a programming error or bug in it and it cannot interpret its own command line commands. What is interesting is that I did a Google search on this problem, and I found numerous postings about the same problem with RealVNC, but not one had a solution to this problem. About your cmd utility: did I understand it correctly that you supposed to run it on the server end, so that if the connection gets lost, it will be restored from the server end without human interaction? Will that work on Windows Vista and Windows 7 if you get bumped out by the UAC?

Cheers, John ----- Original Message ----- From: vnc-list-bounces at realvnc.com To: vnc-list at realvnc.com Sent: Sat Feb 27 05:28:53 2010 Subject: VNC over SSH Hello there, I've got a question about connecting to my VNC server over SSH from a Macintosh. I've got my VNC server running on a CEntOS 5.4 box. If I just enter the IP address & firewall port (i.e. 10.16.0.136:7) I can connect fine using Real VNC's "VNC Viewer Enterprise Edition" version E4.5.2 client software from my Mac (OS X 10.5.8), or using the "VNC Viewer Free Edition" version 4.1.2 on my PC (XP). However, problems arise when I try to initiate a connection over SSH (i.e. 10.16.0.136 localhost:7). On the PC, it seems to work fine -- although, is there a way to verify that the connection is indeed over SSH? The connection info panel doesn't seem to indicate either way. On the Mac, when I try to connect over SSH, I get this error: "getaddrinfo: nodename nor servname provided, or not known (8)" A Google search turned up articles pointing to Apple's implementation of OpenSSL. I was just curious if anyone else had this same problem.
