NAME
tcpdchk - tcp wrapper configuration checker
SYNOPSYS
tcpdchk [-a] [-d] [-i inet_conf] [-v]
DESCRIPTION
tcpdchk examines your tcp wrapper configuration and reports all poten‐
tial 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 prob‐
lem.
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 -DPRO‐
CESS_OPTIONS).
-d Examine hosts.allow and hosts.deny files in the current direc‐
tory instead of the default ones.
-i inet_conf
Specify this option when tcpdchk is unable to find your
inetd.conf network configuration file, or when you suspect that
the program uses the wrong one.
-v Display the contents of each access control rule. Daemon lists,
client lists, shell commands and options are shown in a pretty-
printed format; this makes it easier for you to spot any dis‐
crepancies between what you want and what the program under‐
stands.
FILES
The default locations of the tcpd access control tables are:
/etc/hosts.allow
/etc/hosts.deny
