Server: CentOS 5.6 64bit
Client: Ubuntu 11.04 64bit
TOOL:terminal server client
protocol:vnc
Server Part:
1、Check if vnc server is installed.
[root@localhost ~]# rpm -qa|grep vnc
vnc-server-4.1.2-14.el5_6.6
gtk-vnc-0.3.8-3.el5
gtk-vnc-python-0.3.8-3.el5
If not,install it.
From source:
#yum install vnc-server*
From disc:
#rpm -ivh vnc*
2、configure your vnc server
#vi /root/.vnc/xstartup
remove the comment before line 'unset SESSION_MANAGER' & line 'exec /etc/X11/xinit/xinitrc';
Add a line 'gnome-session';
the whole file as follow:
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
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" &
#twm &
gnome-session
#vncserver
to set the passwd
3、configure your vncservers file
#vi /etc/sysconfig/vncservers
Add following lines:
VNCSERVERS="1:oracle"
VNCSERVERARGS[1]="-geometry 1024x768"
VNCSERVERS="2:root"
VNCSERVERARGS[2]="-geometry 1024x768"
##tip: Every user can start more than one server; when vnc server is started, A sequence number is
assigned to the connection, such as xxx.xxx.xxx.xxx:1; When configure vncservers file , the number
should match the user.
Restart your vnc server
#/etc/init.d/vncserver restart
4、configure the firewall
##tip:the begining port to support vnc server service is 5901 and 5901 is for screen 1,5902 for screen 2 and so on
#vi /etc/sysconfig/iptables
ADD:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT
Restart your firewall
#/etc/init.d/iptables restart
Your VNC server is working now.
Client Part:
It's easy for client part, make sure you can connect to your vnc server via ssh tunnel.
To check if you can connect to the right port:
$ telnet XXX.XXX.XXX.XXX 5901
If you see:
Trying XXX.XXX.XXX.XXX...
Connected to XXX.XXX.XXX.XXX.
Escape character is '^]'.
RFB 003.008
then the port 5901 is open. you can connect the vnc server.
If not, you should check your ssh connection.
Try:$ssh root@XXX.XXX.XXX.XXX to login.
$sudo apt-get install vncviewer
start your tsclient;
fill the computer name using :xxx.xxx.xxx.xxx:1
fill the protocol:vnc
fill the user name: remote server's user name (should match the screen no.)
OK，it works.
