As you may know, on 22nd July 2007, Canonical announced the

steps from being able to easily administer your Ubuntu system. If you
have problems setting up the service or run into problems please call
the support team who'll be happy to help.
Separately to your Landscape account you'll receive an email telling
you about the Canonical support portal where you can enter issues for
the support team through a Web interface.
To get up and running with Landscape you need to do the following:
1. Administrator Account
You will receive an email inviting you to Landscape. Please follow the
instructions in order to create your Administrator login.
2. Organisation Account
Each Account within Landscape represents a group of machines which are
managed by a set number of administrators. The Account login is
needed when a machine is attached to the Account. Your Account
details have been set-up by the support team and are as follows:
Entitlement: A maximum of 1 machine can be registered
3. Administrators join an Account
Each Account can have up to two Administrators set-up for them who
have the ability to manage the machines.
Your nominated contacts will receive an email telling them they've
been invited to your Account. They join the Account by following the
link in the email.
Once they've done this they can login to the Landscape service and see
your organisation's Account.

The Landscape client software enables machines to communicate with the
central server, sending information to the web service and performing
actions requested by registered administrators.

The landscape client is available as an Ubuntu package for Ubuntu 6.06
Dapper, Ubuntu 6.10 Edgy and Ubuntu 7.04 Feisty from the landscape
website. To enable the landscape package repository please add a file
named landscape.list to /etc/apt/sources.list.d/ . The file should
contain one of the following lines, depending on the Ubuntu version of
the computer being enabled.

about the computer and the account. More specifically:
1) Computer Title - a short descriptive title for the computer.
Use the hostname if unsure.
2) Account Name - the account name provided above. The account
name is seen in the URL, and may also be found when editing
the account information.

After installation the system will register with the central Landscape
server. This registration process may take several minutes.

will be shown in the list of 'Pending Computers'. An administrator
with access to the account may then accept the pending computer to be
able to manage this machine with Landscape.
