Changes
=======
Since version 2.7:
Bug Fixes:
Ensure that the -put or -post options to wwwoffle have one URL. Fix IPv6
checking (configure fails if IPv6 not available). Fix conditional request
problem (304 reply for non-conditional requests). Make the socket binding
errors less confusing. Fix requesting of compressed data. Handle NULL strings
in FTP code and parsing requests. Speed up wildcard matching of '/*' paths.
When search script fails give an error not a blank page. The content-length
header is not removed unless compression is being used. Fix core dump with
configuration page adding first item to DontGet/DontCache section. Preserve
cache file timestamps when compressing them. Handle relative URLs that start
with '//'. Fix Solaris compilation problem with statfs/statvfs. Bug fix for
failure to censor some headers. Remove the 'alt' attribute from disabled
images when modifying HTML.
New Features:
Re-instate the old configuration editing web pages due to user demand.
Allow wildcards to have more than two '*' in them.
The upgrade-config.pl script warns about URL-SPECs with path='/' not '/*'.

Subject: GTK+ user interface libraries, version 2.0
Date: Mon, 18 Mar 2002 11:42:07 CST
The GTK+ team is proud to announce the release of version 2.0 of the
GTK+ widget toolkit and associated libraries (GLib, Pango, and ATK).
The result of 3 years work with contributions from hundreds of
volunteers, GTK+-2.0 represents a major step forward in free software
user interface toolkits.
What is GTK+
============
GTK+ is a multi-platform toolkit for creating graphical user
interfaces. Offering a complete set of widgets, GTK+ is suitable for
projects ranging from small one-off projects to complete application
suites.
GTK+ is based on three libraries developed by the GTK+ team:
- GLib is the low-level core library that forms the basis of GTK+ and
GNOME. It provides data structure handling for C, portability
wrappers, and interfaces for such runtime functionality as an event
loop, threads, dynamic loading, and an object system.
- Pango is a library for layout and rendering of text, with an
emphasis on internationalization. It forms the core of
text and font handling for GTK+-2.0.
- The ATK library provides a set of interfaces for accessibility.
By supporting the ATK interfaces, an application or toolkit can
be used with such tools as screen readers, magnifiers,
and alternative input devices.
GTK+ has been designed from the ground up to support a range of
languages, not only C/C++. Using GTK+ from languages such as Perl and
Python (especially in combination with the Glade GUI builder) provides
an effective method of rapid application development.
Earlier versions of GTK+ have been used in a wide range of
applications; perhaps the most well known examples being the GNOME
desktop and the GNU Image Manipulation Program (GIMP). Version 2.0 of
GTK+ offers the same flexibility that made GTK+-1.0 and GTK+-1.2 so
popular, and adds a much enhanced feature set, increased ease of
programming for application developers, and ease of use for end users.
GTK+ is free software and part of the GNU Project. However, the
licensing terms for GTK+, the GNU LGPL, allow it to be used by all
developers, including those developing proprietary software, without
any license fees or royalties.
GTK+ 2.0 is the foundation of the GNOME 2.0 desktop, to be released
later this year. GTK+ 2.0 will be available in standard installations
of Solaris, Linux, and HP-UX.
What's new in GTK+-2.0
======================
To list just a few of the new features in GTK+-2.0:
- Enhanced internationalization support via Pango including full
Unicode support throughout all GTK+ widgets, and support for
all the world's major scripts, including along with Roman,
Cyrillic, and Asian scripts, right-to-left scripts
such as Arabic and Hebrew, and Indic scripts such as Devanagari.
- A powerful text widget, supporting multiple views of a single buffer,
a complete set of options for styled text, and the full range of
internationalization capabilities provided by Pango.
- A flexible widget for tree and list display, with
features such as a model-view split for abstracting data storage
from display, the ability to create custom models to accommodate
large data sets, versatile display/rendering features, and
editable data cells.
- Support for accessibility technology via ATK
- Integration of the gdk-pixbuf library for loading and manipulating
images.
- Hundreds of improvements to the programming interfaces to address
specific difficulties developers had with earlier versions of GTK+.
- Usability improvements, including comprehensive support for keyboard
navigation.
- A clean and attractive new default appearance.
- Abstraction of the type and object system so that it can be used
not just for widgets, but for programmatic objects throughout the
GTK+ libraries.
- Previews of ports to Microsoft Windows and direct frame buffer display.
(A final version of the Windows port is expected within a month
or two.)
- Systematically simplified and enhanced API based on thousands
of user requests and questions fielded by the GTK+ team. This has
resulted in many hundreds of small API tweaks and additions too
detailed to list here.

Subject: KSnuffle-2.2 released
Date: Mon, 18 Mar 2002 11:48:59 CST
Thanks!
==========[snip]========
KSnuffle, the KDE network packet sniffer, is now available for download
from:
ftp://195.92.31.34/ksnuffle-2.2/ksnuffle-2.2.tgz
This version has been built against a fairly recent KDE2.1 CVS snapshot.
The manual pages are online at
http://www.quaking.demon.co.uk/ksnuffle.manual
The main change from 2.1 is a work-around for the forthcoming KDE
change whereby setuid programs will not be run.
Please note that if the remote sniffer interface is not compatible with
2.0 and earlier versions. If you use remote sniffers, then you will need to
reinstall the rsnuffle daemon.
A few people have asked about RPMs. Sorry, none avaiable. I've got a
non-standard setup anyway, and there are two many combinations (RH, Suse,
Mandrake, installed under /usr or /opt/kde, etc.) to do this. Volunteers?
Regards
Mike Richardson
mike@quaking.demon.co.uk
=====[The Actual Announcement]========================================
KSnuffle is a network packet sniffer for KDE. Features include:
* Basic filtering and packet selection via the GUI
* Advanced filtering and packet selection via filter programs
* Multiple concurrent monitors
* Text and binary logging, plus replay of binary log files
* Textual display of network traffic overview
* Full(er) details of protocol and application data available
* Display of data in TCP/IP streams
* Network load histograms and time-averaged load display
* Parallel display of multiple load histograms
* Save and restored filter and packet selection configurations
* Support for use by selected non-root users
* Plugin support - 0.8 contains plugins for
* TCP/IP stream monitoring
* DNS lookup monitoring,
* Traffic summaries
* End-to-End summaries
In its current state it is, so far as I can tell, quite reliable. The
main area where is is lacking is actually decoding different network
packets. At the moment, it handles basic decoding of TCP/IP and UDP/IP,
plus ARP/RARP and ICMP. Packet decoding does not go down into the
application level except for DNS packets.
Also, KSnuffle uses libpcap-0.4, as used by tcpdump. As I only have access
to Linux boxen, I cannot build or test it for any other Unix. I'd be
interested if anyone else could try.
KSnuffle is available from ftp://195.92.31.34/pub/ksnuffle-2.1/ ; there
is a homepage at http://www.quaking.demon.co.uk/ksnuffle.html. The latter
contains some screen shots and other information.
