Installing VNC in CentOS 5/6

When you are installing make sure the Desktop Environment is already installed.

Installing VNC Server in CentOS 6
yum install tigervnc-server
vncpasswd #to configure vnc to user

To Start vncserver
vncserver:2
To Stop
vncserver –kill :2
vim /home/root/.vnc/xstartup
#twm &
exec gnome-session &

Display setting
vncserver :2 –geometry 800x600 –depth 24

Installing VNC Server in CentOS 5.x
yum install vnc-server
vim /etc/sysconfig/vncserver
#locate and make change as follows. Where 2 is Display Number and root is the user
VNCSERVERS="2:root"
#uncomment and remove –localhost
VNCSERVERARGS[1]="-geometry 1024x768 –nolisten tcp –nohttpd"

Now let's assign VNC password to the user root. As I am already logged in as root I will not be switching user.
vncpasswd

service vncserver start
vim /home/root/.vnc/xstartup
#comment twm &
#twm &
#Add to run in gnome
exec gnome-session &

service vncserver restart
chkconfig vncserver on

Zimbra Mail Error: not enough free space in mail queue

If you are using Zimbra Mail and you are not able to send any mails and also you see an Error Message " not enough free space in mail queue " under /var/log/message. Then you should try out this solution. 1. Login to the server, and then again login as zimbra as follows: #su - zimbra 2. Check the Postfix message_size_limit, by default it should be 10MB (i.e. '10240000' bytes) as follows: $postconf message_size_limit message_size_limit = 10240000 3. If the value is higher than that, set it as follows to 10MB $ zmprov modifyConfig zimbraMtaMaxMessageSize 10240000 $ postfix reload Now try sending Mail, It should work. You could try out this solution for Error: " SMTP Server Reported: 452 4.3.1 Insufficient System Storage "
