I have a question about this part and how it applies to RedHat 7.0.

As you probably know, RedHat 7.0 moves entries from the inetd.conf file
to individual files in the /etc/xinetd.d directory.  I checked the file
/etc/xinetd.d/telnet and found this:

----------------------------------------------------------------------------------------------------
# default: on
# description: The telnet server serves telnet sessions; it uses \
#       unencrypted username/password pairs for authentication.
service telnet
{
         disable = no
         flags           = REUSE
         socket_type     = stream
         wait            = no
         user            = root
         server          = /usr/sbin/in.telnetd
         log_on_failure  += USERID
}
----------------------------------------------------------------------------------------------------

I'm using hosts.allow and hosts.deny, but I don't see anything about 
/usr/sbin/tcpd in there.  Should it be?
