LTP Automation
using autoltp

Prerequisites

• All LTP installation prerequisites must be met
  
• Perl modules Net::SFTP and Net::SSH::Perl must be installed on MASTER machine. (www.cpan.org for instructions/downloads)
• MASTER and TARGET machines must have sftp and ssh capabilities.
  
• IP addresses may replace hostnames in this document if name service is unavailable.
  

Install files

• Go to http://ltp.sf.net -> Downloads -> Download latest version of LTP
• Login as root on MASTER machine
• Untar ltp-xxxxxxxx.tgz in /root
• tar -xzvf <filename.tgz>
• mv ltp-<yyyymmdd>.tgz ltp (<yyyymmdd> should be replaced with the drop date you are using

Setup/Edit config files

• edit runalltests.sh and modify the run line to include the PAN_LOG options:
• ex: ${LTPROOT}/pan/pan -l $PAN_LOG -e -S $instances $time -a $$ -n $$ -f ${TMP}/alltests
• tar up the ltp directory (this is the ltp.tgz that is copied to the TARGET machines)
• in the root directory of MASTER type tar -czvf ltp.tgz to tar up the testcases
• copy the resulting ltp.tgz to /tmp on MASTER (autoltp will look for /ltp.tgz in the tmp directory)
  

Run LTP

• cd to /root/ltp/auto on MASTER
• create a config file that contains the list of hosts (TARGETS) to run LTP against
• example config file:
  host1,username,password,number of instances,time
  host2,username,password,number of instances,time
• host is the hostname of a TARGET machine
  
• username is usually root or a root privileged account
• number of instances is how many copies of LTP you want running simultaneously
• time is the duration of the ltp run where 10m = 10 minutes, 2h = 2 hours, etc
• run ./autoltp -f <config file>
• autoltp will then attempt to make ssh/sftp connections with your TARGET machines and run the LTP testcases
