  Beware of TightVNC. One thing I like about RealVNC on a Mac is that I

  collaborate with, who know my VNC password, being able to connect
  while I'm not present and this timed approval is great for that.
  However, anybody connecting with TightVNC crashes every time I
  approve the connection when this approval setup is in place.

 Please describe the problem in more details. How does that look like
 when anybody connecting with TightVNC crashes? We are very interested
 to resolve this problem if it's a problem of TightVNC.

In my office I've the same problem, it should depend by the protocol 
and 
color depth. With hextile and 24bit it works.

 We use UltraVNC on our Windows machines, and it's free as far as I

 have had better luck with the UVNC server than with the Real one, 
 but the vncviewer works about the same.  RealVNC maintains the 
 protocol, and when UVNC, TightVNC, etc., want to create some new 
 kind of packet, they apply to RealVNC for a number, and AFAIK, 
 RealVNC gladly hands it out.  I'm guessing that UVNC was written 
 by guys more familiar with MSWindows (only because it's not on 
 other platforms, not because of code quality; I haven't really 
 compared the codebases).  I think the protocol is designed so that 
 unknown packet types are ignore/dropped, so that a viewer and a 
 server can always talk to one another, provided that they're both 
 using the same *version* of the protocol.  That's the beauty of 
 RealVNC maintaining the protocol for everybody; all the various 
 flavors can all talk with one another (again, if they use the 
 same version).  If U're having trouble with a viewer and a server 
 from different packages not communicating, it could be because 
 they're not both using the same version of the protocol.

But UltraVNC is not conforming to the protocol. The UltraVNC client
has a chance to work with all other *current* RFB conforming servers,
but a client that is strictly conforming to the RFB protocol cannot
communicate with the UltraVNC server.

UltraVNC extended the protocol without coordinating with the RealVNC
protocol maintainers, and as a result everybody else must select
if they should have warts in the code that is outside the specs (and
a possible broken implementation should RealVNC decide to use the
mechanism used by UltraVNC for something of their liking) or drop
support for communicating with the UltraVNC server outright.

UltraVNC is in the embrace-and-extend camp and is a nasty piece of
work if you ask me.  Sure, other implementations also extend the
RFB protocol, but most do it without sacrificing interoperability.
Or, at least they try to.

Caveat emptor: This was the situation last time I had a look, but
I doubt it has changed since.

Thanks. With the many customers I connect with, it sounds like it is safer to 
keep RealVNC or risk not being able to connect to customer.

seem to take forever.  Its not bandwidth because I can connect to XP
machines and the speed is just fine.  Even the Win7 computer on the desk
next to mine when I connect to it, is very slow.


Most likely it is in the screen-update settings at the remote machine. 
Since most msWindows based vnc I know do a capture of the display memory 
once in a while, best to set the screen-settings as basic as possible. 
Then twiggle with the screen update settings and see what suits your needs.


In the end, native protocols like rdp for mswindows will have better 
implementation with the display-software and hence perform better.

On the Windows OS would one be better to use free UltaVNC server and client 
than Real?
What is the advantage of UltraVNC?

Then on Mac OS I would stick with my Vine Server and Chicken of the VNC (Real

Does UltraVNC play nice with the Vine Server / Chicken of the VNC on the Mac OS

Yep - the main reason we are still on XP is W7. 64-bit version slower than 
32-bit version on respective platforms. Then the IE9 mess of 64-bit 
incompatibilities and 32-bit running faster than 64-bit.
Someone took Microsoft into emergency surgery and installed a pace maker to 
keep them going with a crippled platform and a crippled strategy. Bring out the

2011-03-15 Thread Long, Phillip GOSS
Dale:

We use UltraVNC on our Windows machines, and it's free as far as I 
know (I'm not involved in licensing and that kind of noise).  I 
have had better luck with the UVNC server than with the Real one, 
but the vncviewer works about the same.  RealVNC maintains the 
protocol, and when UVNC, TightVNC, etc., want to create some new 
kind of packet, they apply to RealVNC for a number, and AFAIK, 
RealVNC gladly hands it out.  I'm guessing that UVNC was written 
by guys more familiar with MSWindows (only because it's not on 
other platforms, not because of code quality; I haven't really 
compared the codebases).  I think the protocol is designed so that 
unknown packet types are ignore/dropped, so that a viewer and a 
server can always talk to one another, provided that they're both 
using the same *version* of the protocol.  That's the beauty of 
RealVNC maintaining the protocol for everybody; all the various 
flavors can all talk with one another (again, if they use the 
same version).  If U're having trouble with a viewer and a server 
from different packages not communicating, it could be because 
they're not both using the same version of the protocol.

Thanks, 

On the Windows OS would one be better to use free UltaVNC server 
and client than Real?
What is the advantage of UltraVNC?

Then on Mac OS I would stick with my Vine Server and Chicken of 
the VNC (Real VNC based).
Does UltraVNC play nice with the Vine Server / Chicken of the VNC 
on the Mac OS if I switch on the Windows OS side?

Great point. Is there a difference between UltraVNC and TightVNC?
The server and viewer are free right?
Which web site to use to obtain them?
I am thinking of switching from RealVNC on PCs. Assume those will
connect with anyone still using RealVNC?

On the Macs we use VineServer from Redstone and Chicken of the VNC 
from
Geekspiff.
Any suggested free alternates?

Try UltraVNC.



TightVNC 2.0 supports that as well.

I have installed on an XP system running as Service Mode, but with 2
different users that need to log on/off. When I connect with the single user
(under which I installed VNC) it works fine, but if I log out to switch
users, as soon as I type in the password to log on, the viewer window
closes. I cannot get it to log on to a second user account if there is
already one user logged on.
