Chapter 13 13
Remote Access
13.1 Network Transparency
The manpage for X calls it a portable, network-transparent window system. The
phrase network-transparent refers to the location-independence of the clients and
server??”the client may be on the same machine as the server or on machines spread
all over the planet, as long as he has a network connection to the server.
In this chapter, we??™ll examine how to use remote clients and entire sessions, and the
security and performance implications involved in remote access.
Remote access always involves two or more hosts, and when discussing this topic, it
can be easy to confuse which machine is which. Throughout this chapter, I??™ve
adopted the convention of calling the computer on which the X server is running
blue, and the computer on which the remote client is running red. The machine
name is embedded into the shell prompt in the examples: blue$ is the shell prompt
for the X server machine, and red$ is the shell prompt for the client machine.
As virtualization and partitioning technologies such as Xen, Solaris
compartments, and VMware grow into widespread use, X??™s network
transparency gains new value.
