#  Date             : 8/23/94
#  Description   : This is a NFS traffic
#      generation script. It will attempt to
#      generate RPC requests that reflect the
#      type of RPC requests that are generated
#      by the normal network work-load.
#
#################################################
# When running this script you must be super user
# and should set permissions accordingly.

# Display NFS client information before you
# reinitialize the settings.
