Hi all,
Here is a bash script to check the number of login attempts of a user into the server, this script displays all the users in the system and provides you the option to check the login attempt details of a particular user.
------------------------------------------------------------------------------------------
#!/bin/bash
echo ======================================================================
echo The users in the System are:
awk -F'[/:]' '{if ($3==0) print $1}' /etc/passwd
awk -F'[/:]' '{if ($3 >=500 && $3 != 65534) print $1}' /etc/passwd
echo ""
echo Enter the name of the user whose logins needs to be counted:
read username
echo ""
echo The number of times the user $username has successfully logged into the custom container is
less /var/log/secure |grep $username | grep -ic accepted
echo ""
echo The number of failed login attempts of the user $username into the custom container is
less /var/log/secure |grep $username | grep "authentication failure" | wc -l
echo ""
echo ======================================================================
