FreeBSD Simple setup instructions for TCP Wrappers for FreeBSD. 1. Set up banners.
Banners contain the message displayed, if any, when tcpd is called for a particular service.
Create the banners directory if necessary, and create the banner files as shown below. This finger request has been logged. Set up your banners appropriately. If you don't want a banner message, you can simply omit the corresponding file. By doing this, you can have additional security programs drop newly denied host entries into hosts.allow.
