#  FILE   : fsx.sh
#
#  PURPOSE: Runs the fsx-linux tool with a 50000 iterations setting to 
#	    attempt to uncover the "doread:read input/output" error
#	    received if the latest NFS patches for 2.4.17 from Trond
#	    are not applied. http://nfs.sf.net 
#           
#
#  SETUP: The home directory of root on the machine exported as "RHOST"
#         MUST have a ".rhosts" file with the hostname of the machine
#         where the test is executed.
