Computing Resources for EE122
-----------------------------
  EE122 ("Communication Networks") students are issued accounts on the 
  Instructional UNIX and Windows computers.  They typically compile and
  run their programs on the Solaris SPARC and X86 servers (for names and 
  locations of computers please see http://inst.eecs.berkeley.edu/clients).


Which Servers to Use
--------------------
  The EE122 client/server assignments impose a high load on the servers,
  sometimes because of runaway processes.  So we ask that the students
  use these servers

	  cube.cs.berkeley.edu (Solaris X86)
	  sphere.cs.berkeley.edu (Solaris X86)
	  pentagon.cs.berkeley.edu (Solaris X86)
	  rhombus.cs.berkeley.edu (Solaris X86)

  and avoid the servers that support general light-weight computing and
  the SunRay labs (cory.eecs, nova.cs, star.cs, solar.cs, h30.cs, h50.cs).

  Students should kill any backgrounded processes before they logout.


Picking a Unique Network Port
-----------------------------
  Some EE122 assignments require that the student opens a network port in
  the non-privileged (non-root) range, above 1024.  To help you pick a
  unique port on a shared computer, you could use a UNIX command that adds 
  5000 to your unique UNIX user ID:

     expr 5000 + `/usr/xpg4/bin/id -u`

  Note that only the servers listed above allow users to open network ports.
