Configuring and Using the Remote Execution Facility (REX)
Chapter 7280
The Remote Execution Facility (REX) allows you to execute commands
on a remote host. REX is similar to the remsh(1) command, except REX
simulates the user’s home environment on the remote host and mounts
the user’s current working directory on the remote host. REX consists of
the following:
•The on command, which is the user interface to REX and runs on the
host where the user is logged in. The host where the on command is
issued is known as the REX client.
•The rexd daemon, which runs on the remote host. The host running
the rexd daemon is known as the REX server.
