I got a LAMP server working in Ubuntu 11.04. Now the problem is that the websites have to enabled and disabled from the terminal. All all of them have to be accessed from http://localhost which is not so much efficient. So I created a VHOSTS, using some tutorials off the net. Here is the coding for it

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    Servername site.com
    ServerAlias www.site.com
    DocumentRoot /home/starx/public_html/site/public
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory /home/starx/public_html/site/public>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
        AllowOverride None
        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>
nGen
    ErrorLog ${APACHE_LOG_DIR}/site-error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/site-access.log combined

    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

Now, still I can't access the page in http://site.com but if i access using http://localhsot/ it is accessed.

I have disabled all others site including default and have just enabled one site i.e. site

How to fix this?
