   Figure (5) Administration Server’s Options Interface

   VII. CONCLUSIONS
  This paper develops a new software for remote system
administration and controlling different operating systems.
The software depends on XML_RPC technique, which is fast
and efficient method to exchange data and commands
between server and agent. The software offers many valuable
tools for controlling essential parts of target systems and
gathering system information suitable for maintaining target
system stability and controlling system usage, also system
administration tools can be used to modify the behavior of
system.
