can u help me learn aircrack or tell me wher u good gide is i worked it out onec but cant cant do it agan

If you require this sort of tool for legal purposes, you will know how to use it, as you will be familiar with advanced networking concepts, and will be able to implement it on your own networks.

We cannot help you with this tool, as we cannot determine your end purpose, and it is possible to misuse this tool.

You should start by reading the official aircrack-ng documentation on the project website (http://aircrack-ng.org/). In fact, this might be all you ever need. You can also browse the wiki and browse and post in the forum (on that site). There is also an Ubuntu Forums thread about this (http://ubuntuforums.org/showthread.php?t=528276), which starts with a tutorial (which may not be sufficiently current for your needs), and then continues on with extensive discussion and support, which may help you if you run into problems.

If you are simply having trouble figuring out how to *install* aircrack on Ubuntu, that's easy--just install the package called aircrack-ng. (One way to do this is in the Software Center.)

Please feel free to continue requesting help with aircrack and similar tools in Ubuntu here on https://answers.launchpad.net/ubuntu, as well as on other Ubuntu support resources such as that forum (if you post there, you should search first to see if your questions have already been answered). As I have somewhat painstakingly gone to the trouble of demonstrating below, mycae's post does not speak for me and it does not speak for this community as a whole. However, while I do not think our society would be improved by restricting computer security knowledge to an elite privileged few in the employ of powerful governments and businesses, I do think you should consider the moral and legal implications of any use to which you put aircrack. Please know that cracking other people's wireless networks is almost certainly illegal without their full and informed permission. I do not claim I think you would do so, but I will say it anyway: please do not use aircrack to violate the rights of others.

@mycae
aircrack-ng is community-supported software, provided in the universe component of the official Ubuntu software sources. This forum is explicitly one of the places where it is appropriate to get support for such software. People have requested and received help with aircrack-ng on this forum before.

Furthermore, aircrack-ng has been discussed extensively in Ubuntu community support channels before, with little to no objection. You may recall that wieman01 (who is now on Ubuntu Forums staff) posted a tutorial about this in 2007, and there was extensive technical discussion and practical support provided by many people to many people in the long forum thread that ensued. Because the thread was being used to give situation-specific cracking advice, one person submitted a deliberately incendiary post objecting to the thread (which was itself edited by forum moderators for terms of use violations, and for which he subsequently apologized). That user also reported the thread as infringing to moderators, and complained to Canonical. wieman01 expressed a willingness to abide by whatever decisions the moderators came to. A moderator temporarily locked the thread for a short time, the pertinent issues were reviewed, and the thread was reopened with no actions taken based on that one user's objections. At that point, the thread was 11 pages long. Now it is 76 pages long, and still highly active.

So unless you can point to an official policy prohibiting discussion of this topic (and considering the above, it's pretty clear that there isn't one), I would personally ask that you not speak for the community as a whole when expressing your own unwillingness to help. Please remember that deliberately setting a question's status incorrectly, in order to prevent people who would otherwise render assistance from doing so, is likely to be seen as an abusive use of Launchpad; it also seems to pretty clearly go against the paragraph in the Ubuntu Code of Conduct about encouraging collaboration.

Hello Eliah,

I am unsure what location you are in, but my understanding of my local laws (no, I don't wish to disclose my name or location explicitly) are that providing information on how to use these tools when you have no capacity to determine what the use is for (ie reasonable grounds for assuming non-illegal use), is in itself illegal.

Perhaps these laws are different in your location, but asking questions which may land people who are trying to help you in hot water is impolite in itself. I will refrain from answering these questions but would encourage responders/helpers to look into their local laws and ensure they are complying with them.

@mycae
The vast majority of countries in the world do not have such laws, and to the best of my knowledge there is only one democracy in the world that has them (and they might or might not apply in this situation--I am not a lawyer in any country, much less that one). That democracy is not the United States, and is considerably smaller than the United States, both in territory and population. (My implication is not that the United States is somehow the only important country--instead, I wish to clarify that it is not the United States, since I am located in the United States.) The vast majority of Ubuntu users throughout the world are not subject to such laws. More generally, neither are the vast majority of people in the world and (more specifically) the vast majority of computer and Internet users in the world.

aircrack-ng is developed openly, publicly, and legally. Its website is registered in Belgium and hosted in France; its official blog is hosted in the United States by a major and well-respected US Internet company. It has official documentation and forums that are provided openly, publicly, and legally. aircrack-ng is not primarily developed on Launchpad, but Launchpad *is* one of the places where it is (openly, publicly, and legally) developed, because it is provided downstream in Ubuntu. Its codebase in Ubuntu is available in full at https://code.launchpad.net/ubuntu/+source/aircrack-ng, and it is free open source software, so its source code is self-documenting. (Anyway, your country's laws also probably prohibit giving people the tool itself.)

"but asking questions which may land people who are trying to help you in hot water is impolite in itself."

What is impolite (among other things) is exporting your own country's authoritarianism. I respect your personal choice not to help people with aircrack-ng and similar utilities, whether that choice be for moral, legal, or other reasons. And I understand that you may feel (and may be correct) that refraining from doing so is mandated by laws to which you are personally subject. But just because you have the misfortune to be subject to the whims of bad policymakers doesn't mean everyone is. Telling an international community not to ask questions about a topic because your country exercises censorship of the topic is unreasonable. It is also imperialism. Please don't do it. (One way of interpreting your post is that you will stop doing this. I hope that is what you mean.)

Some countries have laws that ban certain religions or certain books, music, or films, such that Ubuntu software or derivatives related to them (or to accessing or playing them) could be illegal to use or discuss. Some countries have laws that outlaw the use of anonymization technologies like tor and freenet (and even traditional web proxies) and punish those who disseminate information about them. Some countries crack down on the use of social media for activism, such that someone in such a country who helped activists with technical questions about social media could, as you say, land in hot water. Some countries have laws that outlaw working on certain days, such that some official Ubuntu events would be illegal to participate in or perhaps even to promote. In some countries, most or all use of strong encryption is illegal, such that it might be a serious crime even to run SSH or sign the Ubuntu Code of Conduct on Launchpad. In a few countries, people have argued that it is illegal to play DVD's using methods that are widely described on Launchpad and in Ubuntu Forums; we provide instructions on how to use software that may be illegal in some jurisdictions, and we expect people to exercise personal responsibility in determining whether or not to use that advice. In at least one country, women are prohibited from driving cars, and that country has no free speech protections for anyone, so someone subject to its laws could plausibly be punished for providing advice to women about the use of street GPS devices with Ubuntu. You may think your country is special and that it is uniquely okay for you to impose your own society's oppressive idiosyncrasies on people in other cultures, but if you think that, you are wrong.
