terminal servers can be accessed from Linux using rdesktop, an open source 

client for the remote desktop protocol (RDP). The URL for this useful tool is:

http://sourceforge.net/projects/rdesktop/

Citrix delivers with its MetaFrame Suite ICA clients for several operating 

systems, including an ICA Client for Linux.

Using this technique, many applications can be moved to the server based 

model. Your migration path in this case introduces the possibility of moving from 

a fat to a thin client. This approach is especially worth considering for clients that 

fit into the Fixed Function and Transactional Workstation roles as defined in 

Table 3 1 on page 28.

A new approach to server based computing is given by the developers of 

NoMachine NX, who are able to reduce network traffic on both X and RDP 

sessions enormously. Since the code for the NX server is under GPL, free 

implementations will be available soon and maybe give the possibility for an 

ubiquitous desktop. More information can be found on their Web site:

3.3  Human factors

As a desktop client migration affects end users in a very direct way, considering 

human factors in the transition management strategy is very important. 

You can expect that a radical change in the desktop interface from what users 

are accustomed to will cause different kinds of reactions: From enthusiastic 

acceptance to outright rebellion. Therefore it is important to keep the end users 

informed about the new developments in a clear and understandable way. A 

communications plan is key. 

Figure 3 1 on page 34 provides an example of a new technology acceptance 

curve in an organization.
