That's a pretty impressive list of hosts but at least the half of it doesn't exist anymore. Then you got some hosts (that probably really work) with pretty strange rules of getting an account (like please guess our secret number ,what takes about a week or so). So up till now i found no easy way to find anything worth. I sent a couple of e-mails but no reaplies yet coz they have no automated system.
So in general i have an impression like "Welcome to Unix" :-(
I'll post the link to a working server if i find any. It seems to me like i'm gonna spent some time on it (i hope i will not end by reinstalling Mandrake)

tcpdchk
TCPDCHK(8) System Manager's Manual TCPDCHK(8)
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. Daemon 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.
FILES
The default locations of the tcpd access control tables are:
/etc/hosts.allow
/etc/hosts.deny
SEE ALSO
tcpdmatch(8), explain what tcpd would do in specific cases.
hosts_access(5), format of the tcpd access control tables.
hosts_options(5), format of the language extensions.
inetd.conf(5), format of the inetd control file.
tlid.conf(5), format of the tlid control file.
