tcpdchk - tcp wrapper configuration checker
tcpdchk [-a] [-d] [-i inet_conf] [-v]
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 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.
The default locations of the tcpd access control tables are:
/etc/hosts.allow
/etc/hosts.deny
