how to use: vncserver and vncviewer

linuxandtsm · 03-21-2012, 09:28 AM

Hi eSelix,

I did not find "/etc/X11/default-display-manager" but looks like twm is the window manager here.
But anyway can i install any other window manager package like Gnome or Kde etc on this RHEL5 box and configure .vnc/xstartup file so that i can see the GUI ?

looks like there are some gnome packages installed already but not sure how to configure so that i can use it ?

Code:

]# rpm -qa |grep gnome
gnome-python2-gnomevfs-2.16.0-1.fc6
gnome-mime-data-2.4.2-3.1
gnome-keyring-0.6.0-1.fc6
gnome-doc-utils-0.8.0-2.fc6
gnome-vfs2-2.16.2-6.el5_5.1
libgnomeui-2.16.0-5.el5
gnome-python2-canvas-2.16.0-1.fc6
gnome-mount-0.5-3.el5
gnome-python2-gtkhtml2-2.14.2-7.el5
gnome-python2-bonobo-2.16.0-1.fc6
libgnomecanvas-2.14.0-4.1
libgnome-2.16.0-6.el5
gnome-python2-2.16.0-1.fc6
gnome-python2-gconf-2.16.0-1.fc6
rhn-setup-gnome-0.4.20-46.el5
gnome-python2-extras-2.14.2-7.el5

Thanks in advance!

Sorry, there was a display manager "kdm". A window manager I have as symlink in "/etc/alternatives/x-window-manager". You should be able to use another one. KDE window manager is called "kwin" and GNOME - I think "metacity".

kill all the cureent running vncserver and restart the server with following changes

Code:

#vncserver -kill :2

Code:

#vi /etc/sysconfig/vncservers
 VNCSERVERS="2:root"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost" <---donot uncomment this line

Code:

#vncpasswd

Code:

#service vncserver restart

Code:

#vi /root/.vnc/xstartup
#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER  <--------dont uncomment this line
 
exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

Hi deep27ak,

Followed but no change. Still endup with text based white console with xclock displayed on right on the vncviewer window.

I use gnome-session rather than twm.

Hi Les Windoze,

could you tell me how to use gnome-session ?
If you mean just putting a "exec gnome-session" in .vnc/xstartup file, then i tried that.

And i am not sure how to check if gnome related packages are installed and how to use them.
Thanks!

It seems there has not been any resolution. I am having similar problem setting up a vnc session server on Redhat 5.

Please i created a vnc sersion between Redhat linux 5 and windows server 2003. Redhat linux is the vnc server while window server 2003 is the vnc viewer. I can not connect to Redhat despite starting Redhat. I have an error in windows.

VNC Viewer :Error
Unable to connect to host: Connection refused(10061)

There is network connection between both and their hostname can also be resolve.(hosts file contains ipaddress and hostname).

VNC viewer in Linux can access the windows(I installed both VNC server and viewer on windows). Redhat 5 has both VNC viewer and server installed when the OS is installed.

I started up vnc server from services and it is running.
The following below is the command to start and the error log message.

[root@idsl01 ~]# vncserver -geometry 1920x1200

New 'idsl01:3 (root)' desktop is idsl01:3

you should have started a new thread as your problem seems to be different. Here OP is able to connect to vnc but not able to get proper display and you are not at all able to connect to vnc server
The possible reasons can be

# server firewall is blocking
# vncserver service is not running
# vncserver is not configured properly
