As noted, Ethereal is licensed under the GNU General Public License. The GPL imposes conditions on your use of GPL'ed code in your own products; you cannot, for example, make a "derived work" from Ethereal, by making modifications to it, and then sell the resulting derived work and not allow recipients to give away the resulting work.

As noted, Wireshark is licensed under the GNU General Public License. The GPL imposes conditions on your use of GPL'ed code in your own products; you cannot, for example, make a "derived work" from Wireshark, by making modifications to it, and then sell the resulting derived work and not allow recipients to give away the resulting work.

Ethereal can read live data from Ethernet, Token-Ring, FDDI, serial (PPP and SLIP) (if the OS on which it's running allows Ethereal to do so), 802.11 wireless LAN (if the OS on which it's running allows Ethereal to do so), ATM connections (if the OS on which it's running allows Ethereal to do so), and the "any" device supported on Linux by recent versions of libpcap.

Yes, if, for example, you mean "I work for a commercial organization; can I use Ethereal to capture and analyze network traffic in our company's networks or in our customer's networks?"

The English pronunciation can be found in Merriam-Webster's online dictionary at http://www.m-w.com/cgi-bin/dictionary?book=Dictionary&va=ethereal. According to the book "Computer Networks" by Andrew Tannenbaum, Ethernet was named after the "luminiferous ether" which was once thought to carry electromagnetic radiation. Taking that into consideration, Ethereal seemed like an appropriate name for something that started out as an Ethernet analyzer.

Note that it applies only to our more recent releases (starting in November 1999): Zip 2.3, UnZip 5.41, WiZ 5.01, MacZip 1.04, and subsequent updates. All older releases are still covered by our old COPYING file (UnZip) or the README file in official Zip distributions.

A#1.4: The GNO documentation specifies that the minimum requirement is an Apple IIGS with 1.25 MB of memory and a 3.5" disk drive. Realistically (especially with all the third-party add-ons), a hard drive (or other large mass storage device) should be considered a necessity. An accelerator and additional memory is recommended. There is not an official "minimum disk space" requirement as yet. When this information becomes available, it will be added to this FAQ.

Ethereal can only capture on devices supported by libpcap/WinPcap. On most OSes, only devices that can act as network interfaces of the type that support IP are supported as capture devices for libpcap/WinPcap, although the device doesn't necessarily have to be running as an IP interface in order to support traffic capture. On Linux and FreeBSD, libpcap 0.

The most likely reason for this is that Ethereal is trying to look up an IP address in the capture to convert it to a name (so that, for example, it can display the name in the source address or destination address columns), and that lookup process is taking a very long time. Ethereal calls a routine in the OS of the machine on which it's running to convert of IP addresses to the corresponding names.

Yes. Any product conforming to the J2EE 1.3 or later specifications can be used to run this benchmark. CTS certification ensures that the application server being tested is a J2EE technology-based application server and not a benchmark-special application server that is crafted specifically for SPECjAppServer2004. The CTS certification is validated by Sun Microsystems, Inc.

The J2EE 1.4 specification is final and you can use the J2EE 1.4 SDK to deploy applications today. However, for improved reliability,scability, and performance, it is recommended that you deploy your applications on J2EE 1.4 commercial implementations that will be available early in 2004. If you want to deploy your application before 2004, and reliability,scability, and performance are critical, you should consider using a high performance application server that supports J2EE v1.

Older versions of the Red Hat RPMs for Ethereal put only the non-GUI components into the ethereal RPM, the fact that Ethereal is a GUI program nonwithstanding; newer versions make it a bit clearer by giving that RPM a name starting with ethereal-base.

The source code to your product does not have to be Open Source as long as it does not contain fragments of OpenGatekeeper or OpenH323 source.

Probably. libsrs2 is released under the union of the GPL version 2 and the BSD licenses. You may choose which license to use with this software. If neither of these licenses is adequate for your needs, plesae contact Shevek at srs [ta] anarres.org to ask for alternative licensing terms and support.

The Rolls Ethereal list people on the Rialto, at least name and electronic address, and often interests, location, and awards. The Rolls are maintained by Justin du Coeur <rolls@waks.org> They are available via World Wide Web at http://www.waks.org/rolls

I see it as a triple pun. The library is insubstantial, existing only "in the ether"; the subject matter is spiritual; and the medium is, well, an ethernet—at least on this end. Some people have complained about the word Ethereal—that it connotes "airy" or "unreal." In fact, I changed the name to "Christian Classics Electronic Library" for a while, but that seems rather boring and forgettable.

When it approved the seaway and power project, the IJC appointed the International St. Lawrence River Board of Control (ISLRBC) to oversee the regulation of water levels and flows and ensure that the Orders of Approval are followed. One assignment carried out by the ISLRBC was to develop a regulation plan to determine flows through the project that are consistent with the Orders of Approval.

m0n0wall is under the BSD license, which basically means that you can do whatever you want with it (including modifying and selling it) for free, as long as the original copyright notice and license appear somewhere in the documentation and/or the software itself. There are no warranties of any kind though. Although you don't have to pay anything for m0n0wall even if you sell it, if you do find yourself making money by selling m0n0wall-based products, a donation would be very much appreciated.

Yes. Squirrel is distributed under zlib/libpng license and is 100% free for both commercial and non-commercial products.

Sure. Minify is distributed under the New BSD License, which means that you're free to use, modify, and redistribute Minify or derivative works thereof, even for commercial purposes, as long as you comply with a few simple requirements. See the LICENSE file for details.

Support for particular protocols is added to Ethereal as a result of people contributing that support; no formal plans for adding support for particular protocols in particular future releases exist. If a network analyzer writes out files in a format already supported by Ethereal (e.g., in libpcap format), Ethereal may already be able to read them, unless the analyzer has added its own proprietary extensions to that format.

this stage it is a pre-commercial product that was developed to confirm its feasibility for application to both domestic and international markets. As a result of field tests conducted in an extensive product validation program, we have identified a variety of improvements that are being incorporated in the new BioMax? 25 and BioMax? 50 prior to their commercial sale.

Yes. There are two different categories of PhysioToolkit code, and the rules for using them are slightly different. The WFDB library is free under the GNU Lesser General Public License (LGPL). The LGPL permits you to use (or sell, or give away) the library with your own code. The only significant restriction is that you must make the sources for the library itself freely available. You do not need to disclose the sources for your own code simply because you have used the WFDB library with it.

Sure, use your current joystick instead of my primary and secondary panels. Either add a DB25 connector to the back panel of your commercial stick for the other panels to plug into (and wire it into your commercial stick's encoder), or remove the encoder from the commercial stick and mount it in a project box and connect the commercial stick using DB25 connectors like in the plans included here.

Yes, you can use your account for commercial purposes. The World Wide Web has become the most efficient and cost-effective means of making information available to the users of the Internet community and we encourage our customers to utilize such an enormous medium.
