The following guidelines should be followed by anyone distributing a software package containing Wireshark: 1. URLs. 1.1. Wireshark web site. The Wireshark web site URL is http://www.wireshark.org/ . 1.2. Wireshark releases. The canonical location for every Wireshark source release is http://www.wireshark.org/download/src/all-versions/, e.g. http://www.wireshark.org/download/src/all-versions/wireshark-0.99.55.tar.bz2 If your packaging system downloads a copy of the Wireshark sources, use this location. Don't use http://www.wireshark.org/download/src. 1.3. Artwork. Logo and icon artwork can be found in the "image" directory in the distribution. This is available online at http://anonsvn.wireshark.org/wireshark/trunk/image/ 2. Licensing. Wireshark is released under the GNU General Public License version 2. Make sure your package complies with this license. 3. Privileges. In versions up to and including 0.99.6, it was necessary to run Wireshark with elevated privileges in order to be able to capture traffic. With version 0.99.7, all function calls that require elevated privileges have been moved out of the GUI to dumpcap. WIRESHARK CONTAINS OVER ONE POINT FIVE MILLION LINES OF SOURCE CODE. DO NOT RUN THEM AS ROOT. There are two configure-time options on non-Windows systems that affect the privileges a normal user needs to capture traffic and list interfaces: "--enable-setuid-install" and "--with-libcap". Setting "--enable-setuid-install" to "yes" will install dumpcap setuid root. This is necessary for non-root users to be able to capture on most systems, e.g. on Linux or FreeBSD if the user doesn't have permissions to access /dev/bpf*. It is disabled by default. If the "--with-libcap" option is enabled, dumpcap will try to drop any setuid privileges it may have while retaining the CAP_NET_ADMIN and CAP_NET_RAW capabilities. It is enabled by default, and requires the Linux capabilities library. Additionally, warnings are now displayed when Wireshark and TShark are run as root. 4. Customization. Custom version information can be added by creating a file called "version.conf" and running "make-version.pl -p". See make-version.pl for details. If your package contains significant changes we recommend that you use this to differentiate it from official Wireshark releases. 4.1. Source-level version detection. The SVN version corresponding to each release is in svnversion.h. It's defined as a string. If you need a numeric definition, let us know. 5. Trademarks. Wireshark and the "fin" logo are registered trademarks of Gerald Combs. 6. Spelling. Wireshark is spelled with a capital "W", and with everything else lower case. E.g., "WireShark" is incorrect.
