You can use this script to check port connectivity for your servers. On this script, I only checked “22” and “1521” port which belongs to ssh and Oracle Database. Please take a look the script and change it as you wish. Also, script ‘ll be creating an HTML file that you can send it to your e-mail.
If you create a user named “usrcntrl” on the destination server, this script will be report memory usage for the HP-UX server to. Please do not forget to define ssh key-paring for “usrcntrl” user.
