I think you are confusing SSH timeouts (which I get sporadically myself
when connecting to my business LAN) with the VNC freeze. In my
experience, the VNC freeze only occurs when the underlying network
connection itself hangs. Although it may appear that the problem is
VNC-related (since you ca

Thanks Andy.
It may be something in the network which is causing VNC to freeze,
however if that is the case then VNC appears to be causing the network
problem. My rationale is that the freeze mostly happens immediately
after I bring the VNC window to the foreground. Also, the if I set a

No - all machines are connected on wired links.

Mark,
I think Andy is suggesting that the problem is SSH timing out the tunnelled
connection - this theory is supported by the fact that the server sees the
connection drop.
VNC clearly isn't causing any network problems, since you can still interact
with the SSH session.
Cheers,
Wez @ RealVNC L
OK. I have set sshd to run at debug level 3 (maximum). I compared logs
for a normal VNC connect, use, disconnect session and a connect, use,
wait-till-freeze session.
The output is almost identical. The only difference is that there were
a few more messages like "debug2: channel 0: rcvd adjust 901
Wez,
is it possible this is related to the "hang" (in actuality,
looping) that I have been working with you on?
Mark - if you look at the Windows task manager, under the "Processes"
tab, is the vncviewer process "CPU Time" value incrementing?

Ahh... You want two people to be able to use the same PC at the same time. I
don't believe VNC will let you do that. Terminal Server might, but the app
would also have to be capable of running two copies at the same time, which
might be a problem.

Kevin - CPU time in vncviewer remains at zero while active and once
frozen. CPU usage is very low all the time, only occasionally flicking
up to 1 or 2 %, unless I move the VNC window around in which case it
goes up, and then (eventually) CPU time does increment.
While looking at this, VNC viewer
I got the impression that the OP wanted to, as an example, have two people
working on different Excel spreadsheets at the same time on the same PC.
Obviously that's not going to work as only one person can input data at a
time, even with "shared sessions."

Sure VNC does.
You just set the preferences to allow multiple clients to connect to the
same machine. I do that all the time. Helpful when other developers and
myself both need to look at the desktop for a given remote box with a
problem.

Mark,
I'd recommend running VNC Viewer with full debugging enabled, to see if it
reports any useful information.
Since you don't see the problem when using VNC without SSH, it does seem
likely that something is amiss with your SSH tunnels.
I'm not sure I understand your timer comment, but it is
Pedro,
VNC will definitely not let you run two programs at the same time. Terminal
Server, if run on a Win 2000 Server will let you have more than one person
logged on to the same computer in two different consoles. AFAIK, this won't
work on Win XP. If you want to run one instance of this progr
Remote Desktop on XP will not allow it.
Terminal services on 2003 server will allow it.

Hi All,
Still no connection from my work computer to my host home computer. Am I
missing some setting on my host computer that could be blocking this
specific ip address. Or would the problem more likely be on the viewer
computer?

As an experiment, please try this: install one of the older

See if you can establish a connection to that VNC Server.
If that works...we'll know better how to peel this onion.
Scott,
Really? How will that help?
Lee,
It sounds like you're got some problem with the Hosts/Access Control
setting, so that you've configured VNC Server to block connections from
certain/all IP addresses - it doesn't sound like blacklisting at all.

Sorry for not being obvious: the 3.3.7 version does not

I'm pretty sure the newer viewers are fully compatible
with the older versions, so there should be no troubles there.
Good luck!
