RE: VNC Viewer
Hi Brett, Assuming you are using Windoz The history of the VNC Viewer is stored in the registry : HKEY_CURRENT_USER\Software\ORL\VNCviewer\MRU A list of your addresses will be there. You just have to remember to list each entry in the "index" string. The first letter shown in your index value will be the address that it shows when you run the VNC Viewer prog. Eg: "index"="ABC" "A"="my-pc" "B"="friends-pc" "C"="NT-Server-PC" So, you could just make up a list then add it to the registry :) Regards, Daniel -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Brett J.

RE: Dr. Watson error on Win NT 4.0 SP 6
We have a similar issue with WinVNC 3.3.3R9, running on Compaq WinNT 4.0 server with SP6a, IIS4.0 Frontpage2000 extensions, MDAC2.6, Compaq NIC. We have about 10 servers running similar configurations, and had been quite happy with the previous version of WinVNC 3.3.3(R3?). With 3.3.3R9 Installation runs fine with the spiffy new installation tool. We run VNC on an "as needed" basis, so when we want to use it we go into NT server manager and fire up the WinVNC server service. The first time I used it it was fine, but after that I would start the VNC service, then run the VNC client and try to access the server. Normally the client comes right back with either a "server not found" or the server window. In this case you don't see any dialog boxes for a couple minutes, and then it comes up with a socket error message. On the server side you see a Dr. Watson Error. Shutting down and restarting the service doesn't help. I deinstalled 3.3.3R9 and installed 3.3.3R7, and everything is happy again, except for the fact that I really miss the new cut and paste feature R9 added.

CORBA-enabled VNC for a Classroom
Hi -
I've patched the 3.3.3r2 UNIX Xvnc server to link against the ORBit
CORBA library and export a CORBA management interface. Here's the IDL:
interface VNC {
void enableClientKeyboard(in string ipaddr);
void disableClientKeyboard(in string ipaddr);
void enableClientPointer(in string ipaddr);
void disableClientPointer(in string ipaddr);
void disconnectClient(in string ipaddr);
void disconnectAllClients();
};
As you can see, it permits client keyboards and pointers to be
individually enabled or disabled by IP address. I've also added a
server option "-foreignersdisabled" to start foreign (non-localhost)
clients with keyboard and pointer disabled. I use this in a class I
teach to have the students start all their VNCs disabled. Then I
connect from localhost as the one enabled client and use a Perl script
to turn their keyboards on and off. I've attached both the patch and a
simple Perl script to manipulate the CORBA interface.
I guess what I'd like to see next (I don't know if I'll do this myself)
is to have two different passwords, one to attached enabled, one to
attach disabled; the second one possibly NULL. This should probably
done with a real config file for the server.
Comments?

RE: vnc intermittently slow
That's a pretty heavy question. There are only several hundred products to choose from out there. I'll pass along info I have reguarding packages the I'm familiar with. If you want free there is NetSaint. It runs on Linux and it very versatile however configuring it is still labor intensive and if you're not comforatble with Linux you may spend alot of time and not get much from it. Available from SourceForge at http://netsaint.sourceforge.net/ There is also the open network management system that is available for free. I don't know anything about it but their web site is http://www.opennms.org . This software is free and most likely runs on Linux and/or Unix. We use a product call WhatsUp Gold made by IPSwitch. I find it effective in mopnitoring netowrk devices and port availablity. It has a nice web interface and isn't too terribly expensive. I runs on WinNT. I don't think it is as effective monitoring servers and applications as some other products. Last I checked approx $700.00, this may have changed so don't quote me on that. http://ipswitch.com We also use a product call SiteScope made by Freshwater software out of Boulder, CO. http://www.freshwater.com I administer this product and I'm VERY familiar with it. It runs on Win NT or Sun Solaris 2.6. The NT install is a breeze. The Solaris install is much more involved as you need to add a number of other packages to Solaris first, but the actual SiteScope install script has worked beautifully for me. It has a very simple web interface and I was able to figure out how to use it and start creating monitors in about 45 minutes. Cost varies depending upon how many monitors you need to setup but the pricing info is available on their web site. You can download a free 10 day trial of the software if you like. Personal opinion, SiteScope is easier to configure and has a nicer interface than WhatsUp Gold. SiteScope really excells at monitoring servers, applications, and websites. It does have the ability to monitor network devices and can perform SNMP gets but WhatsUp may be stronger in this area. When I was still on active duty and stationed at the Air Force Research Lab we had a producted call NetHealth made by Concord. It ran on a Solaris workstation. I don't know what other platforms it runs on. It think this provided great reports concerning network devices and was very useful for trend analysis but it provided no realtime alerts if a device went down. I also, at the time, didn't have a web interface although I strongly suspect this has changed by now. At the Air Force Research Lab I also administered Spectrum made by Cabletron. This is a very heavy duty network monitoring tool similiar in function to HP Openview. Very expensive, ran on Solaris, and quite time consuming. Just as HP Openview is. This is probably over kill for your organization. If you have any other questions you can e-mail me directly at [EMAIL PROTECTED] Hope this info has been useful.

What could I be missing??? I would like to take this chance to mention something very similar that I have seen when I started working with the viewer code on PocketPC's (CE 3.0), trying to accelerate it to a more usable level. I have put in video acceleration code and other modifications, and it is now quite fast enough WHEN IT WORKS NORMALLY. But sometimes, it just gets ridiculously slow. I have a Linux box (RH7.0), Gnome, 240x320 desktop, depth/visual doesn't matter. It seems to be most noticeable when moving through the "Start" menu from the taskbar (OK, I'm sure that's not what Gnome calls it, but that what it looks like). Usually, it is fine, and then, out of the blue, it starts drawing so slowly that you can SEE each individual scanline of the update region being drawn. This is on a network that consists of two machines - the server and the viewer. There are *NO* collisions. Network speed in other applications is fine. Using something like forwarded X sessions from one Linux box to another through the NIC in the Linux box (with or without OpenSSH X forwarding) never exhibits this problem. Data transfers of large files (10+ MB) between the Linux box and CE unit occur at full speed, without drops. The exact same behavior (everything I've mentioned so far, except for the X session stuff) occurs whether my network link is a 10Mb/s link or a 115200baud (.1Mb/s) PPP link. When the slow down occurs, it is just as bad on the 10Mb/s link as it is on the .1Mb/s link. I think it is some kind of multithreading resource contention in the viewer. I say this for a variety of reasons: 1. Windows has some major problems with thread scheduling. Sometimes threads are arbitrarily boosted in priority, sometimes they are dropped. Thread priorities in the presence of hardware interrupts gets even more interesting, and I don't even want to start on the subject of Interrupt Service Threads vs. Interrupt Service Routines... 2. I have experienced major performance differences when I adjust the relative thread priorities of the drawing thread and the other threads. I did this by adjusting the priority of the drawing thread, because that was the one I was most interested in (because of video acceleration modifications). I would be very interested if someone would be willing to drop me an architectural overview of the viewer so I could see the thread interactions more clearly. My work so far has been examining the bark of the trees, which makes it extremely difficult to form a coherent picture of the forest... 3. In my case, the slowdown only occurs for less than a minute. Comparing this to the hours or days of slowdown in the above case suggests to me a lockstepping problem. If you think of the thread synchronization operations occurring at some frequency, then when you put the two (or more) frequencies (threads) together, you will get a beat frequency (lockstepping). The nature and duration of the "beat" will depend on the CPU speed, relative cost of executing the code in the various threads, local code vs. OS system calls, and a ridiculous number of other parameters. It is entirely possible that on "almost all" machines, these parameters work out such that the "beat" is infrequent and of very short duration, making it easily misinterpretable as a networking hiccup or temporary congestion. It also makes it excruciatingly difficult to debug - after all, if it has to run for hours to start doing it, how can you be sure that you fixed it? You can't put a breakpoint on the code that only fires when the beat occurs without already knowing what the cause of the beat is... This is one of the reasons I would like to see an effor made to rewrite the viewer without multithreading (but I get ahead of myself...) 4. I know that, at least in CE, the GDI, the serial driver, and the networking stack have a tendency to hose each other. This was causing some overall speed issues originally, which have been resolved, but the acute slowdown that I have described has persisted through every change I have made. 5. My thesis work was on distributed parallel computing, with a focus on harnessing idle CPU cycles. As such, I have a first-hand and relatively painful awareness of Windows mishandling of thread priorities. I would like to point out that I do not consider this a "fault" of the viewer. I strongly suspect that the problem is in Windows

Thread priorities in the presence of hardware interrupts gets even more interesting, and I don't even want to start on the subject of Interrupt Service Threads vs. Interrupt Service Routines... 2. I have experienced major performance differences when I adjust the relative thread priorities of the drawing thread and the other threads. I did this by adjusting the priority of the drawing thread, because that was the one I was most interested in (because of video acceleration modifications). I would be very interested if someone would be willing to drop me an architectural overview of the viewer so I could see the thread interactions more clearly. My work so far has been examining the bark of the trees, which makes it extremely difficult to form a coherent picture of the forest... 3. In my case, the slowdown only occurs for less than a minute. Comparing this to the hours or days of slowdown in the above case suggests to me a lockstepping problem. If you think of the thread synchronization operations occurring at some frequency, then when you put the two (or more) frequencies (threads) together, you will get a beat frequency (lockstepping). The nature and duration of the "beat" will depend on the CPU speed, relative cost of executing the code in the various threads, local code vs. OS system calls, and a ridiculous number of other parameters. It is entirely possible that on "almost all" machines, these parameters work out such that the "beat" is infrequent and of very short duration, making it easily misinterpretable as a networking hiccup or temporary congestion. It also makes it excruciatingly difficult to debug - after all, if it has to run for hours to start doing it, how can you be sure that you fixed it? You can't put a breakpoint on the code that only fires when the beat occurs without already knowing what the cause of the beat is... This is one of the reasons I would like to see an effor ma

current display
Hi All, I have finally figured out how to get the viewers to work both ways. But I'm having a little problem. First a little background: When I use Linux to view a windows desktop on Win2k, I can see a simultaneous response from the windows machine. Anything I move from the viewer moves on the Windows desktop. Now lets reverse it. If I run the server on the LInux machine, I can connect and see a great drawing of the desktop. But what happens on the viewer is not what happens on the Linux screen. I've tried to find out what the current display is and here is what I've found so far: when server is run for the first time, it assigns display 1 by default. And sure enough, there's a log file for it. So to be sure there is no mixup of the displays, I kill 1 and try to run the server on display zero. But the system returns the message that display zero is already running. Bu there's no log file for it. If I run Kmail on the server after I've used it from the viewer, Kmail will not start. If I log out, log in and start Kmail again, it works fine. Can anyone tell me what I need to do to make sure that the server is using the current display? - Scott Dunn, Linux Newbie [EMAIL PROTECTED] Smiles are free. - To unsubscribe, send a message with the line: unsubscribe vnc-list to [EMAIL PROTECTED] See also: http://www.uk.research.att.com/vnc/intouch.html -

Win95 locks up after login
Recently I've been trying to remotely help a friend with her PC, she's using Windows 95 OSR2. There's NO icon in the tray on her taskbar, even though the VNC server is running. This is not important, but nonetheless, it might indicate what's wrong on her machine, and might help with the deadly problem this is all about: Everytime I log in, I see her screen and receive a few seconds, but then her machine locks up. She can't do anything and needs to do a hard reboot! Also, I get disconnected everytime. The longest view-session I have had took about 5 seconds. It seems that each time I'm logged in and when one of us move her mouse, her Windows 95 locks up completely. She does not have any other situations/software that locks up her Win95. She's installed the latest release ( WinVNC.exe compiled 16/03 ), and I'm using 2 versions of vncviewer, in FreeBSD and in Win98SE, both have the exact same result on her end of the line... She's got a coax-cable LAN internet connection, Winsock 2 installed and her connection is working fine otherwise. Any insight on how she might prevent this from happening? Are there any registry settings I could send her, so that she can enter a .reg and this might not happen anymore? As long as I can't get in properly and can't take a good look at her machine, problems won't be over, since I can't do much... For this I really need to get in first!

Re: Single window control on Mac and Linux
>I've been playing with the single window control version of WinVNC (allowing >remote control of a single application or Window instead of the entire >desktop). Has anyone tried porting this to the Mac and to Linux? On Linux, it's easy - just start the application on Xvnc without a window manager. Virtually all X11 applications accept the -geometry switch which will let you rescale it to full screen, otherwise you just make Xvnc the same size as the application window. On the Mac, it's *much* harder. I can't offhand think of a good way to do it, particularly as the menu bar would have to remain available to leave a sensible UI. In any case, you'd still have to dedicate the Mac to it, so why not just install one of the "Mac protection systems" or even Multiple Users, and secure the machine that way? The one caveat I can think of is that ChromiVNC is not tested with Multiple Users. For MacOS X you can use the Xvnc trick as above (for an X11 app) or you're back in the MacOS situation. I really don't know enough about OS X to comment on whether it's possible to do it "on screen" with an Aqua app. -- from: Jonathan "Chromatix" Morton mail: [EMAIL PROTECTED] (not for attachments) big-mail: [EMAIL PROTECTED] uni-mail: [EMAIL PROTECTED] The key to knowledge is not to rely on people to teach you it.

What could I be missing??? I would like to take this chance to mention something very similar that I have seen when I started working with the viewer code on PocketPC's (CE 3.0), trying to accelerate it to a more usable level. I have put in video acceleration code and other modifications, and it is now quite fast enough WHEN IT WORKS NORMALLY. But sometimes, it just gets ridiculously slow. I have a Linux box (RH7.0), Gnome, 240x320 desktop, depth/visual doesn't matter. It seems to be most noticeable when moving through the "Start" menu from the taskbar (OK, I'm sure that's not what Gnome calls it, but that what it looks like). Usually, it is fine, and then, out of the blue, it starts drawing so slowly that you can SEE each individual scanline of the update region being drawn. This is on a network that consists of two machines - the server and the viewer. There are *NO* collisions. Network speed in other applications is fine. Using something like forwarded X sessions from one Linux box to another through the NIC in the Linux box (with or without OpenSSH X forwarding) never exhibits this problem. Data transfers of large files (10+ MB) between the Linux box and CE unit occur at full speed, without drops. The exact same behavior (everything I've mentioned so far, except for the X session stuff) occurs whether my network link is a 10Mb/s link or a 115200baud (.1Mb/s) PPP link. When the slow down occurs, it is just as bad on the 10Mb/s link as it is on the .1Mb/s link. I think it is some kind of multithreading resource contention in the viewer. I say this for a variety of reasons: 1. Windows has some major problems with thread scheduling. Sometimes threads are arbitrarily boosted in priority, sometimes they are dropped. Thread priorities in the presence of hardware interrupts gets even more interesting, and I don't even want to start on the subject of Interrupt Service Threads vs. Interrupt Service Routines... 2. I have experienced major performance differences when I adjust the relative thread priorities of the drawing thread and the other threads. I did this by adjusting the priority of the drawing thread, because that was the one I was most interested in (because of video acceleration modifications). I would be very interested if someone would be willing to drop me an architectural overview of the viewer so I could see the thread interactions more clearly. My work so far has been examining the bark of the trees, which makes it extremely difficult to form a coherent picture of the forest... 3. In my case, the slowdown only occurs for less than a minute. Comparing this to the hours or days of slowdown in the above case suggests to me a lockstepping problem. If you think of the thread synchronization operations occurring at some frequency, then when you put the two (or more) frequencies (threads) together, you will get a beat frequency (lockstepping). The nature and duration of the "beat" will depend on the CPU speed, relative cost of executing the code in the various threads, local code vs. OS system calls, and a ridiculous number of other parameters. It is entirely possible that on "almost all" machines, these parameters work out such that the "beat" is infrequent and of very short duration, making it easily misinterpretable as a networking hiccup or temporary congestion. It also makes it excruciatingly difficult to debug - after all, if it has to run for hours to start doing it, how can you be sure that you fixed it? You can't put a breakpoint on the code that only fires when the beat occurs without already knowing what the cause of the beat is... This is one of the reasons I would like to see an effor made to rewrite the viewer without multithreading (but I get ahead of myself...) 4. I know that, at least in CE, the GDI, the serial driver, and the networking stack have a tendency to hose each other. This was causing some overall speed issues originally, which have been resolved, but the acute slowdown that I have described has persisted through every change I have ma

Hi all,
OK - I am checking out VNC and I have either got the wrong end of the
stick entirely or I am really slow :-)
I have "VNCServer PPC" running on my iMac (OS9.04) with an IP address
of 192.168.0.253 (subnet masks and all other things are correct). So
I go to a Mac 6400 (OS9) with an IP address of 192.168.0.71 and it
had the "Client" running and have logged on...but what am I supposed
to be seeing on the 6400 ('viewer') - all I get is the menu bar
andnothing else...
I am confused.
Any kind soul like to tell me (politlely) where I am going wrong?
Thanks for the bandwidth.
