Daemons utilizing tcp_wrappers

While glancing over "Hardening Red Hat Enterprise Linux 5" by Steve Grubb from Red Hat, I came across a nice little tip.  I always knew the common daemons which were compiled with tcp_wrappers support, but somewhere in the back of my mind I always wondered how to get a definitive list of all daemons on my system which were compiled with tcp_wrappers. 

Following output generated on Fedora11 and only pertains to executables in /usr/bin and /usr/sbin.


$ sudo egrep libwrap /usr/bin/* /usr/sbin/* | awk -F 'bin/' '{print $2}' | awk '{print $1}' | sort
exportfs  
hoststat
mailq
mailq.sendmail
mailstats
makemap
