    NAME
         tcpdchk - tcp wrapper configuration checker

    SYNOPSYS
         tcpdchk [-a] [-d] [-i inet_conf] [-v]

    DESCRIPTION
         tcpdchk examines your tcp wrapper configuration and reports
         all potential and real problems it can find. The program
         examines the tcpd access control files (by default, these
         are /etc/hosts.allow and /etc/hosts.deny), and compares the
         entries in these files against entries in the inetd or tlid
         network configuration files.

         tcpdchk reports problems such as non-existent pathnames;
         services that appear in tcpd access control rules, but are
         not controlled by tcpd; services that should not be wrapped;
         non-existent host names or non-internet address forms;
         occurrences of host aliases instead of official host names;
         hosts with a name/address conflict; inappropriate use of
         wildcard patterns; inappropriate use of NIS netgroups or
         references to non-existent NIS netgroups; references to
         non-existent options; invalid arguments to options; and so
         on.

         Where possible, tcpdchk provides a helpful suggestion to fix
         the problem.

    OPTIONS
         -a   Report access control rules that permit access without
    	  an explicit ALLOW keyword. This applies only when the
    	  extended access control language is enabled (build with
    	  -DPROCESS_OPTIONS).

         -d   Examine hosts.allow and hosts.deny files in the current
    	  directory instead of the default ones.

         -i inet_conf
    	  Specify this option when tcpdchk is unable to find your
    	  inetd.conf or tlid.conf network configuration file, or
    	  when you suspect that the program uses the wrong one.

         -v   Display the contents of each access control rule.  Dae-
    	  mon lists, client lists, shell commands and options are
    	  shown in a pretty-printed format; this makes it easier
    	  for you to spot any discrepancies between what you want
    	  and what the program understands.
