RHEL 6 - Upon GUI Login Present successful and unsucessful User Login
 
I have a customer requirement that stipulates when users login to RHEL6 they be presented with there last successful login and in the case of a bad login, between successful logins, when (date/time) the bad login occured.

Does anyone have a script and if so where can I place this script in the users startup.

A million thanks,
Johnny Mac:scratch:

vim /home/USER_NAME/.bashrc

Code:

grep -i failed /var/log/secure | tail -n 10

The above only works as root and only in console (not graphical user interface). Solution was I modified the /etc/rsyslog.conf to write /var/log/secure messages to a second location. When users login they grep against the second file (users read only) for bad logins. The second request (succesful logins) I identifed the solution by going to Red Hat's website, https://access.redhat.com/site/solutions/217423

Note:
To get the application to startup upon user login, I used the graphical interface System - Preferences - Startup Application. Here under command I typed, gnome-terminal and then the path to my grep script along with the file name and extension.

Below is my rsyslog.conf (/etc/) and script:

script - grep -i failed /var/log/secures | tail -n 10
