(NOTE you'll need a window manager
yum install vnc-server
rpm -ivh vncserver
for each user that will be using vnc, run the command "vncpasswd"
/etc/sysconfig/vncservers
VNCSERVERS="1:user1 2:user2 3:user3" VNCSERVERARGS[1]="-geometry 640x480" VNCSERVERARGS[2]="-geometry 640x480" VNCSERVERARGS[3]="-geometry 800x600"
service vncserver start
service vncserver stop
login as each user and edit the xstartup.sh
!/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 &
If you really tried anything with port and :1 after your linux box ip try disabling your linux firewall by typing
service iptables stop
and try entering into your vnc again. If the problem will be solved you have to follow these simple steps:
step 1: open the iptables config vi /etc/sysconfig/iptables
Step 2: Insert this Line: -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT
Step 3: enable iptables again service iptables restart
