NAME<\/a> tcpdchk \u2212 tcp wrapper configuration checker<\/p>\n tcpdchk [-a] [-d] [-i inet_conf] [-v]<\/p>\n tcpdchk<\/i> examines your tcp wrapper configuration and reports all potential and real problems it can find. The program examines the tcpd<\/i> access control files (by default, these are \/etc\/hosts.allow<\/i> and \/etc\/hosts.deny<\/i>), and compares the entries in these files against entries in the inetd<\/i> or tlid<\/i> network configuration files.<\/p>\n tcpdchk<\/i> reports problems such as non-existent pathnames; services that appear in tcpd<\/i> access control rules, but are not controlled by tcpd<\/i>; 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.<\/p>\n Where possible, tcpdchk<\/i> provides a helpful suggestion to fix the problem.<\/p>\n
