www.domain.com open but domain.com doesnt

I have hosted my site on linode vps and my site open only with www.domain.com and not with domain.com

how to correct this one..

explian your question please. when i went on your site i typed fourthmolar.com

it works fine. redirects me to www.fourthmolar.com

i think thats what it is supposed to do.

I have good link with explanations and samples about redirections, read it

here are few tips which I using:

#RewriteCond %{HTTP_HOST} ^www.mysite.ru$
#RewriteRule ^(w+)$ http://$1.mysite.ru [301,L]

RewriteRule ^index.html$ index.php [L,NE]

thanks for ur posts but i solved it myself after posting the problem here
