tcp_wrappers provides host-based access restrictions on tcp services:
facilities for monitoring and filtering incoming requests for the SSHD,
SYSTAT, FINGER, FTP, TELNET, RLOGIN, RSH, EXEC, TFTP, TALK, and other
network services.

The package provides a tiny daemon wrapper program that can be installed
without any changes to existing software or to existing configuration
files.  The wrappers report the name of the client host and of the
requested service; the wrappers do not exchange information with the
client or server applications, and impose no overhead on the actual
conversation between the client and server applications.

This is a routine update to recent upstream (debian) patches. It
also synchronizes with the current cygwin-1.7 tcp_wrappers package.

[[ compiled using gcc-3.4.4-999 ]]

This will most likely be the final tcp_wrappers update for the
cygwin-1.5 distribution; future development will continue with
tcp_wrappers-7.6-20 for cygwin-1.7.

This release is specific for cygwin-1.5. It differs significantly from the
simultaneously-released tcp_wrappers-7.6-20 for cygwin-1.5. In addition to
the usual (trivial) documentation differences, this cygwin-1.5-specific
package does NOT support IPv6, while the cygwin-1.7 package does.

Because of this, the /etc/defaults/etc/hosts.allow files also differ;
the cygwin-1.5 version can not include the IPv6 localhost specification.

(cygwin-1.7) ALL : localhost 127.0.0.1/32 [::1]/128 : ALLOW
(cygwin-1.5) ALL : localhost 127.0.0.1/32 : ALLOW


CHANGES (since 7.6-4)
========================
o Updated to latest debian patchset (r16 v. r14)
o Added the following line to the default /etc/hosts.allow
  *before* the PARANOID entry:
      ALL : localhost 127.0.0.1/32 : ALLOW
  Technically, an entry like this is only required on
  cygwin-1.7, but I wanted to sync up before cygwin-1.5
  goes into permanent deep freeze.
o Updated hint files

A reminder for package maintainers and developers:

        STRONGSYMS: the cygwin versions of cygwrap-0.dll AND libwrap.a
        (that is, both the DLL and static library) explicitly provide
            int deny_severity
            int allow_severity
        symbols.  This means that clients must NOT define their own
        versions of these symbols, as is the practice on *nix systems.
        Instead, clients should rely on the /declaration/ provided in
        tcpd.h:
            extern int deny_severity;
            extern int allow_severity;
        This may require code changes in clients that link against
        libwrap, but it was a necessary API change to enable DLL
        builds on cygwin.
