Win2003 login remotely to FC4 via VNC

zillah · 12 May 2006 at 06:20

I know that there are heaps threads about this topics , but this what I did without any success

This is what I did on FC4 I am logging as root (I know the security implication)
First:
[root@localhost ~]# rpm -q --info vnc-server

Code:

Summary	 : A VNC server.
Description :
The VNC system allows you to access the same desktop from a wide
variety of platforms. This package is a VNC server, allowing others to
access the desktop on your machine.

Second:
The gedit /etc/sysconfig/vncserver

Code:

# The VNCSERVERS variable is a list of display:user pairs.
# Uncomment the lines below to start a VNC server on display :2
# as my 'myusername' (adjust this to your own). You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted! For a secure way of using VNC, see
# <[url="http://www.uk.research.att.com/vnc/sshvnc.html"]URL:http://www.uk.research.att.com/vnc/sshvnc.html[/url]>.
#zillah uncomment VNCSERVERS="2:myusername"
 
[b]VNCSERVERS="2:root"[/b]
#zillah uncomment VNCSERVERARGS[2]="-geometry 800x600"
[b]VNCSERVERARGS[2]="-geometry 800x600"[/b]

Third:
[root@localhost ~]# vncpasswd root
Password:
Verify:

Fourth:
[root@localhost ~]# vncserver
New 'localhost.localdomain:2 (root)' desktop is localhost.localdomain:2
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost.localdomain:2.log

Is the command "vncserver" same as "service vncserver start" ?

[root@localhost ~]# service vncserver start
Starting VNC server: 2:root A VNC server is already running as :2

Then from windows, you just need to connect using the viewer, and type
[hostname]:[screennum] in the connect box, and type in the correct

I could not find the option that he(in the quote above) was pointing , could you please look at this and let me what I missed?

Code:

The error message that I received when I typed in the ip address for the address is below:

Code:

[b]VNC Viewer: 198.222.168.189:Error[/b]
unable to connect to host: The requested address is not valid in its context.(10049)

I am using FC4. The fix for me was that the default iptables (i think
thats the firewall settings) were preventing incoming VNC connections.
To overcome this in gnome i went to Desktop>System Settings>Server Settings>Services There I stopped iptables - and immediately I was able to connect!

I did stop iptables as qoute above suggested.

From within FC4 I tried : vncviewer 127.0.0.1:2 (same as vncviewer :2 ),,,,,,it worked.

I tried to configure from GUI method

Desktop - Preferences - Remote Desktop , check the users view and use boxes , uncheck the 'ask you for confirmation' box , set password ,

then - Desktop - Server Settings - Services , tick vncserver box - start - save , (starts at boot up)

Any suggestion ?

Thanks riddlermarc

To connect from your Windows box, use the server name 198.222.168.189:5902, the 5902 bit specifies the screen number

Why do I need to use this number 5902 ? The screen number that I have configured on FC4 was 2.

Is there any criteria to choose the port number which corrospondes to a screen number ?

What if I configured the screen number 3 instead of 2 what will the port number be ?

zillah · 13 May 2006 at 15:22

Just change the last digit of the :590x suffix to match the screen number and you are sorted

It did not work.

Any other idea ?

Can you SSH onto the FC4 box from another box?

I have not tried this, could you please explain the steps to do that.
1- I have got putty client on windows box.
2- What should I enable on FC4 to accept the SSH conversation from putty client on winodws ?

Can you ping the FC4 box from another box?

Yes I can

As/when you do that, let us know what the resulting output is from the command "vncserver :2" (minus the quotes) in your putty window..

Do yo mean I have to issue this command (vncserver :2) on the linux box or the windows box ? I know we can do it on linux box , but on windows, I do not know

zillah · 26 May 2006 at 13:18

then issue the command in the putty window

Ok, I got it , my misunderstood

Output is:

Code:

A VNC server is already running as :2

.. in which case you should be able to connect to the linux box

i feel there is typo here (correct me if I am wrong)

Did you mean to say :
"...in both cases you should be able,,,,,,,,,"

or you meant to say :

",,,,,in what case you should be able ,,,,,,"

If you you meant to say :

",,,,,in what case you should be able ,,,,,,"
My answer will be ssh case.
