Wietse Venema's network logger, also known as TCPD or LOG_TCP.
These programs log the client host name of incoming telnet,
ftp, rsh, rlogin, finger etc. requests.
Security options are:
- access control per host, domain and/or service;
- detection of host name spoofing or host address spoofing;
- booby traps to implement an early-warning system.

tcp-wrappers (7.6.q-20) unstable; urgency=low
* Added patch fix_parsing_long_lines: fixes the /etc/hosts.{allow,deny}
parser to properly detect lines longer than 2047 characters which
would cause the caller to hang forever in a loop. (Closes: #596261)
* Fixed the link ordering of the shared library, patch courtesy of
Matthias Klose of Ubuntu. (Closes: #609598)
* Moved the *.5 man pages from tcpd to libwrap0. (Closes: #630244)
* Converted to multiarch the libwrap0 and tcpd packages.
* Switched to debhelper level 8.
* Hopefully added proper support for overriding CFLAGS and LDFLAGS.
* Removed the -D_REENTRANT flag which has been useless since libc6.

* Moved the documentation in libwrap0 and made the documentation
directory of the other packages a symlink.
* Converted to source format 3.0 (quilt).
* Switched to debhelper level 7.
2009-07-02 - Marco d'Itri <>
tcp-wrappers (7.6.q-18) unstable; urgency=medium
