* debian/control:
+ Set policy to 3.6.1.0.
+ Set debhelper build-dependency to (>= 4.1.68) because of dh_installppp.
+ Removed leading "an" from the short description and enhanced the long
description.
* debian/rules:
+ Use dh_installppp instead of doing the work by hand (Closes: #212909).
-- Sam Hocevar (Debian packages) <sam+deb@zoy.org> Mon, 27 Oct 2003 11:15:48 +0100
rinetd (0.62-1) unstable; urgency=low
* New upstream release, includes our fix for DSA 289-1.
* Set policy to 3.5.10.
-- Sam Hocevar (Debian packages) <sam+deb@zoy.org> Tue, 27 May 2003 15:41:37 +0200
rinetd (0.61-2) unstable; urgency=low
* New maintainer.
* Maintainer upload (Closes: #86201, #145756).
* Fixed then applied a user-contributed patch to make logging non-buffered
(Closes: #163654).
* Added a 1 second delay in the init.d script to avoid restarting rinetd
too quickly (Closes: #180449). This isn't perfect, though: the real problem
is the race condition when using daemon() and writing a PID file.
* rinetd now closes its configuration file (Closes: #182705).
* Fixed an off-by-one overflow and a missing reallocation in handleAccept().
* Replaced malloc/strcpy with strdup in readArgs().
* Added a -f flag to run rinetd in the foreground, and updated manpage and
index.html accordingly.

rinetd (0.61-1.2) unstable; urgency=low
* NMU (bug squashing party).
* Fixed debian/rules (./configure and make clean) (closes: #145756).
-- Sebastien Bacher <seb128@debian.org> Sat, 31 Aug 2002 15:15:25 +0200
rinetd (0.61-1.1) unstable; urgency=low
* NMU.
* Fixed detection of numeric addresses. This fixes a bug that occurs when
starting rinetd in an unconnected machine.
* Added missing includes.
* Added -O2 to compilation options. Added -Wall and -Wstring
compilation options and removed all the warnings.
* Changed a lot of fprintf(stder,...) to syslogs.
* The program was reporting a bogus line number in errors.
* Replaced signal with sigaction.
* Uses autoconf.
* Now it logs DNS errors.
* Checks closing of pid file, this catchs the failure to write the pidfile
due to a disk full.
* Removed unused function Sleep.
* You don't need bind(2) on a socket you'll use for connect(2).
* Uses compatibility mode 4 of debhelper.
* Reload rinetd configuration when a PPP connection goues up. This useful
when using DNS names in /etc/rinetd.conf that can't be resolved without
an Internet connection. The proper solution to this is to resolve DNS
names *each time that is needed* (with perhaps a small caching period).
* Uses logrotate to rotate logs instead of savelog and cron.

Source: rinetd
Section: net
Priority: optional
Maintainer: Sam Hocevar (Debian packages) <sam+deb@zoy.org>
Standards-Version: 3.6.1.1
Build-Depends: debhelper (>= 4.1.68)
Package: rinetd
Architecture: any
Depends: ${shlibs:Depends}
Description: Internet TCP redirection server
rinetd redirects TCP connections from one IP address and port to another,
with basic IP-based access control.
.
rinetd is a single-process server which handles any number of connections
to the address/port pairs specified in the file /etc/rinetd.conf. Since
rinetd runs as a single process using nonblocking I/O, it is able to
redirect a large number of connections without a severe impact on the
machine. This makes it practical to run services on machines inside an IP
masquerading firewall.
