I am trying to install aegir omega and having a hard time with the installation

here is the script instructions :

<code>
###----------------------------------------###
### DNS MANUAL CONFIG ###
###----------------------------------------###
###
### Starting with release 0.4-alpha9 Aegir
### requires proper DNS configuration
### of your server. Your hostname has to be
### FQDN and has to match your server IP.
###
### This script is trying to discover your
### DNS details and allow or deny the install,
### if something doesn't look correct.
###
### This script will also use your FQDN
### hostname as a web address of your Aegir
### frontend (control panel).
###
### You can try to change the automatic
### defaults by setting up your IP address,
### your FQDN hostname and your Aegir frontend
### web address below.
###
### It can be useful when you are using local
### environment with custom settings in your
### /etc/hosts, when you have more than one
### public IPs on eth0 and you wish to use
### non-default (first) IP address, or when
### you want to use non-hostname (sub)domain
### to access your Aegir frontend.
###
### It is also useful when you plan to use
### available in Barracuda optional installs
### of Chive, SQL Buddy and Collectd, since
### all of them will use subdomains in the
### server hostname and it will not work
### when your hostname domain DNS is not
### under your control (like many default
### hostnames and reverse DNS provided by
### VPS hosting companies).
###
### Please change *all 3 values* if you wish
### to customize this automatic setup.
###
### Example:
###
### _MY_OWNIP=192.168.0.108
### _MY_HOSTN=server.mydomain.com
### _MY_FRONT=aegir.mydomain.com
###
### NOTE:
###
### If you will use your custom DNS settings,
### they will be still validated, therefore
### make sure your _MY_HOSTN and _MY_FRONT
### both matches your _MY_OWNIP or the script
### will fail to install Aegir (unless you
### will disable the DNS test completely
### below in _DNS_SETUP_TEST).
###
_MY_OWNIP=""
_MY_HOSTN=""
_MY_FRONT=""
</code>

When I let the setup run and automatically configure itself, I get the welcome email like this:
<code>
admin,

Your new site li229-45 has been created.

You can now login to li229-45 by clicking on this link or copying it into your browser:

http://li229-45/user/reset/1/1294203241 ... c6275008bf

This is a one-time login, so it can be used only once.

Once you have logged in, you will be redirected to http://li229-45/user/1/edit so you can change your password.
