Gimp is included as part of the standard installation of Red Hat Desktop, so you 

just have to start it. A screen shot showing the gimp running on the migrated 

desktop is shown on Figure 6 2 on page 129.

Browser

For our migration scenario, we decided to use the Mozilla Firefox Browser. 

Firefox is the browser only project from Mozilla.org. As we do not need mail 

capabilities (these are provided by Ximian Evolution) using the stand alone 

browser offering from Mozilla seemed reasonable.

We recommend that you check important Web sites or especially Web clients for 

compatibility with the browser before the migration. Some Web sites use 

ActiveX controls or special JavaScript functions, which are only supported by 

Internet Explorer. As this is not the case for our migration client, it is easy to 

make the switch and use Mozilla Firefox instead of Internet Explorer. 

E mail client

In this section we talk about an e mail client.

Novell Evolution with Novell Connector for Exchange 2000

To make our client migration scenario more realistic, we added the requirement 

that existing clients use Microsoft Outlook and Exchange 2000 messaging. So 

our migration task includes migrating from the Windows based Outlook client to 

a Linux based messaging client that provides similar functionality, and integrates 

with the existing Exchange 2000 messaging system.

Our migration solution consists of using the Novell Evolution e mail client in 

conjunction with the Novell Connector for Microsoft Exchange Server 2000/2003. 

The Evolution e mail client has an architecture that supports the building of 

special connectors for different groupware applications. Thus a connector for 

Microsoft Exchange 2000 and 2003 was developed, and was released under the 

terms of the GPL for the first time in May 2004. A key factor in enabling the 

development of the Exchange connectors was Microsoft's inclusion of a Web 

interface to Exchange called Outlook Web Access (OWA). OWA uses webDAV 

for communication to the exchange server message store. So it became possible 

to develop Exchange connectors by implementing a webDAV interface, instead 

of having to reverse engineer the proprietary MAPI protocol of Exchange.

Restriction:

 Only the Exchange versions 2000 and 2003 support webDAV 

connections. As of the writing of this book, a connector supporting native 

Linux client access to full Exchange 5.5 server functionality was still not 

available.
