The OIT Unix cluster systems (details below) share a common  file
system,  common  news  and mail systems, and common users.  This means
users can login to whichever of the systems they want and  their  same
login  id  and  password  will work and their files will be available.
This also means users can do their own "load balancing" by logging  in
to whichever system seems to be best for them at the time.

                     -----  System Details  -----

     The cluster machines (known as session servers) are as follows:

          Session Servers
          ---------------
          holmes.umd.edu
          marlowe.umd.edu
          marple.umd.edu
          tracy.umd.edu
          wolfe.umd.edu

     To  make  all this easier, users of the OIT Unix cluster can just
login to the generic address dc.umd.edu (dc = detective cluster).

     All  mail  sent  to  the   cluster   should   be   addressed   to
@umd5.umd.edu  (which  is  the address that is placed on all
outgoing cluster mail).  Mail sent in this manner can be read from any
cluster system.  The machine known as umd5.umd.edu is also part of the
cluster but acts as a server for the cluster.   DO NOT  USE  UMD5  for
anything other than your EMAIL address.  Never login to umd5.

     Games, IRC, and MUDs are not allowed on the OIT Unix cluster.

     The  home directories contain default .login, .cshrc, and .logout
files.  In addition, the access mode on the home directories has  been
set  to 700.  This means that a student will not be able to copy files
from an unsuspecting student, unless the owner changes the mode of his
home directory to something  that  allows  such  access.    Of  course
students can still MAIL things to each other.

     User  files  are  NFS mounted on various servers.  Symbolic links
are used to create the file names found in the system  password  file.
This  means  the  names  returned by the pwd command may not match the
names found in the system password file.  Users should always refer to
home directories by the ~loginid or $HOME methods.

     The estimated enrollment for your  class  was  used  to  generate
login ids for you, your students and TAs.  All login ids have the same
attributes;  you  and  your TAs can select any of the ids for your own
use.  The details of these login ids are listed at  the  end  of  this
MAIL item.

access, you should contact:
