#initial attempt at an automation script: ltprun
#       3/12/02 William Jay Huie (creation)
#       3/28/02 William Jay Huie minor updates
#this will be kicked off by ltp_master from the master control machine which
#uploads this script and then telnets into each machine and kick this script off
#perhaps by passing a uniq ID to name the LTP_OUTPUT_TAR file by, or 
#allowing the script to create a unique name itself (reccommended for now)
#Check ltp_master for details
#FIXME: One problem is that the tests need to be run as root and this script
#       doesn't as of yet su
#
#CHANGEME:
LTP_HOST=ltp_host.somewhere.org
#This is the user to get the ltp.tgz file from, not who we're running as,
#     that's ocntrolled by ltp_master
LTP_USER=ltp
LTP_PASS=ltp
LTP_TARFILE=ltp.tgz
LTP_RUNALL_OUT=runall.output
LTP_LOGFILE=ltp-logfile
LTP_RUN_OUTPUT=ltprun.out
SAR_OUTFILE=sar.data

#This script relies upon the -l ~/ltp/ltp-logfile pan option in runalltests.sh
#We want to also include in the output tarfile a system_info file 
#   need to determine what goes in that, maybe just modify ver_linux
#   to report this info
