VNC and Windows 7

We have started rolling out Windows 7 and we are experiencing a problem to connecting to PC's that have
Windows 7 on them.  Any suggestions?

Thank you,

multiple connection reset by peer errors

Hi,

I have started facing weird issue of "connection reset by peer" in reverse
connection. The strange thing is on one PC it works fine while on other PC
it gives this error consistently. What could be the reason for this error
message? Do I need to check anything to debug or fix this? Moreover, it
shows "connection is already in progress" message multiple times. I see
below error message.

    /etc/X11/gdm/Xsession: Setup done, will execute:
/usr/local/bin/ssh-agent -- /usr/bin/gnome-session
    X_mkdir: Not owner
    Window manager warning: "" found in configuration database is not a
valid value for keybinding "cycle_windows"
    Window manager warning: Log level 32: could not find XKB extension.

Any ideal would be much appreciated.

Thanks.

Re: VNC and Windows 7


What server version and what client version?  Free edition server won't
work on Win7...

That's the default login session that is showing here. In the 
administrative commands, there is a program to tune and tweak the login. 
Use that to change the settings you like.

That was never possible in the older versions. I donnot know if the 
current version as an option to copy and paste text, I'm relative sure 
other things cannot be copy-n-pasted.

Yes, that is not in the vnc location, it is in the display or 
windowmanager or session manager settings somewhere. Like sharing this 
session or whatever. In the end, it also uses the vnc protocol.

Donnot know mac details. For msWindows, I know programs like webcam 
stuff have a kind of direct access to the display hardware. Vnc is not 
capable of capturing this data and hence, cannot show the contents.

For Unix X11 I know there are applications that show on remote displays 
and hence can show in vnc-sessions as these applications donnot direct 
access to display hardware.

As macs have a native and optionally an X11 display, you might be lucky 
if you try the X11 way and find/use an X11 application that shows the 
display.

On the other hand, if you want to show video contents over a network, 
there are other protocols and programs to use. the most relaxed one I 
have seen is a webcam that frequently dumps a jpeg picture in a 
directory. This so happens to be used in a webpage that has an automatic 
update of roughly the same frequency. Not enough for video, acceptable 
for the oldes webcam use in the world: scanning if there is coffee in 
the pot or ot.

Connecting

I have installed VNC and I am attempting to connect to another computer.

The other computer is the server and the IP is: 10.1.1.2

No matter what I try I am not able to connect.

Any ideas?

John.

VNC servers stop starting up after the 8th user at boot time on RHEL

Hello everyone, 

I'm not sure if this is a vnc issue or a RHEL issue, but I'll start
here. We have 3 machines with RHEL 5.3 64 bit, all updates applied. I
have used password to set the password of my users, then used
vncpassword as that user to set their vnc password, chkconfiged
vncserver on, and I've put all of the users in
the /etc/sysconfig/vncservers file in a format like so: 

VNCSERVERS="1:larry 2:moe 3:curly"

VNCSERVERARGS[1]="-geometry 640x480"
VNCSERVERARGS[2]="-geometry 640x480"
VNCSERVERARGS[3]="-geometry 800x600"

When the machine boots, the vncserver service starts and begins starting
up the vnc servers for users UNTIL it has started up about 8 of them at
which point the server just goes on to starting up the next service. We
have 13 users in the vncservers file so that means that 5 still haven't
been started up. Once the machine has booted, I can issue the command
service vncserver restart   and it will start up ALL 13 users. This
tells me that my config file is good at least, but why dont all of the
users' vnc servers come up at boot?! 

I can change the order of the users in the vncservers file so it looks
something like: 

VNCSERVERS="13:larry 12:moe 11:curly"
VNCSERVERARGS[13]="-geometry 640x480"
VNCSERVERARGS[12]="-geometry 640x480"

Checked your firewall? (TCP/IP settings? You want this dog?)

Sometimes security suites block incoming connections even though you think
the FW's disabled. Windows Firewall may also be blocking, although this is
less likely. Can you ping the host machine from your client machine? If you
grab a copy of nmap and run a port scan on the host, is port 5900 visible
from your client machine?

VNC and Xdmcp, wrong hosts answering

I have realVNC viewer on windows hosts to allow graphic access to Linux
boxes.
On the linux side, I have xinetd with vnc definitions with the arguments
 -inetd -broadcast -once -IdleTimeout 0 -depth 16 -securitytypes=none
-geometry=.....
Within X11, enabled port is 177.No firewalls are enabled between
partners.

On the windows side, when prompted, I put hosta:1 (or hostb or hostc...)
I do get the linux login splash panel but often it's for a different machine
eg calling for hosta, I may consistantly get hostc. When calling for hostb
I may get hosta the first time then hostc then next few times.

So clearly VNC is working but it sounds like something weird is going on
with xdmcp. As far as I can tell, all the hosts are identically configured
but
some are a further distance through network equipment. This almost sounds
like a race condition as to which one responds first.

Trying to telnet to the raw port (5900) on all of these machines works fine
and
consistantly.  The syslogs have not shed any light on this either. Anyone
have any
ideas?

Thanks
