HOW TO CONFIGURE PASSWORD LESS SSH LOGIN.

Now execute below commands to gather mount point information from all the three servers.

SERVERS_LIST=”192.168.216.131 192.168.216.132 192.168.216.133″
for i in $SERVERS_LIST
do
echo “——————————–” >> df_info
echo “* HOST: $i ” >> df_info
echo “——————————–” >> df_info
ssh manmohan@$i df >> df_info
done

and finally all mount point details can be collected from the “df_info” file.
