Warning Banner
 

I am tring to make a warning banner for a linux Red Hat 7.3 box. I have edited the /etc/issue file and the message will come up before the login screen but it goes by to quickly and I really need the message to come up even if there is just a log out. I would like to have the message come up after the user logs in and if possible not allow the user to do anything until they acknoledge the message. Thanks for any help.

How about running a script from bashrc? So everytime you login it will display a banner and wait for any key to continue.

Thanks
