Would you like to create a persistent home volume that will keep your data over __INCOGNITO__ sessions? This means that application settings and file changes in your home directory will persist through computer shutdowns which is not normally the case with __INCOGNITO__ (normally everything is reseted on a reboot)."

QUESTION_SIZE="Enter the size in megabytes for the home volume. ${MIN_SIZE} MB is the smallest we allow, but it is strongly recommended to use more. There will be a recommended value in the input field which work for most users. The recommended value will utilize most space but save a little so that future upgrades of __INCOGNITO__ will fit. If you plan to store other files on the media you should take that into account and decrease the volume size appropriately."
QUESTION_ENCRYPTION="Would you like to encrypt the home volume using TrueCrypt? This is strongly recommended as it will make your data unreadable for everyone that does not have the password you choose unless they can guess it. The only inconvenience added for this is that you will be prompted for the password at each start up."
QUESTION_HIDDEN_VOLUME="Do you want to use a hidden home volume?

<p></a>In this document we try to present the __INCOGNITO__ LiveCD in an easy to understand and reasonably thorough manner in hope to give the new user a crash course in what might be a completely new set of applications and concepts regarding anonymity and security on the Internet. It is quite long so you might want to not read it in one go but instead read the introduction and conclusion, as well as the sections on only those applications you intend to use with the possibility to return to it whenever you want to try something new or use it for reference. If you have experience with these applications and concepts from elsewhere and feel comfortable with the user interface in general, reading this document is maybe not necessary at all. A word of caution to all users is not to alter the network, proxy and firewall settings unless you know what you are doing – poking around with them too much might spoil the built-in defences of __INCOGNITO__.</p>

What one can do is to make the cost of doing that so high that it becomes infeasible. __INCOGNITO__ tries to do this by sending all your Internet traffic through the <a href="https://www.torproject.org/";>Tor™ network</a> which makes your Internet traffic very hard to trace. If someone tries to trace you when you are using __INCOGNITO__, the trail will stop somewhere in Tor network with the IP address of some of its participants, not your. Similarly, if someone tried to see where you ultimately want to send your traffic, they will only reach as far as some computer in the Tor network. In fact, you will be the only one knowing exactly what is going on – not even the computers in the Tor network that you send your traffic through will know the whole picture!</p>

<p>By relaying your Internet traffic through the Tor network (which __INCOGNITO__ does per default) your communications should <em>only</em> be considered to be untraceable back to the computer you use, not encrypted or in any other way hidden. While the traffic <em>is</em> encrypted when it leaves your computer and when you get back your responses, it will not be so when sent between the Tor network and your destination (this is unavoidable for technical reasons). This means that an eavesdropper at some later point will be able see your traffic without Tor's encryption, but will not be able to link it back to your computer.</p>

-<p>The graphical user interface used in __INCOGNITO__ is called KDE and share many fundamentals with that of Microsoft Windows, Mac OS X and most other modern operating systems, so if you have used any of them, getting used to KDE will take no time. As this document is not intended as a complete guide for KDE there are only a few things we will mention here to spare you some time. First of all, in the lower left corner of the screen there is a blue button with a K in it, called the "K menu button". Pressing it opens the "K menu" where you will find short cuts to many different applications. Please explore the different categories of applications and try out those that seem interesting. If there are any KDE or system settings that you want to change, like the screen resultion or KDE's appearance, this can be done in the "Control Center", found at the first level of the K menu. Also notice that there is a category named __INCOGNITO__ which contains some things relevant for the user, like a short cut to this document. The __INCOGNITO__ category is also available from as a quick launch item, located right of the K menu button, among the short cuts to your home directory (where you store your files), Firefox and Thunderbird.</p>

-<p>In the lower right corner you will find something referred to as the system tray, or simply systray, that has a couple of icons in it, each which offers an interface for some running application. One of them helps you keep an eye on the battery level (if you run from a laptop), one allows to instantly change the keyboard layout, and one helps you control the network settings, for instance. You are encouraged to check them out, but we will say more about some of them later on in this walkthrough. You will also see a clock showing its time in UTC (Greenwich Mean Time) which might not be appropriate for your location. To make it show your local time, right-click it and choose "Show timezone" and either choose one of the timezones available there or add your own with the "Configure timezones..." option.</p>

-<p>Some other important things that need to be understood before proceeding are the concepts of a <a href="http://en.wikipedia.org/wiki/Livedistro";>LiveDistro, LiveCD and LiveUSB</a>. In essence a LiveDistro is an operating system (like Windows or Mac OS X, although __INCOGNITO__ uses Linux) that is run from some removable media like a CD or USB memory stick. Most likely you are running __INCOGNITO__ from a CD, which makes it into a LiveCD, and this brings some limitations to its operation. Most importantly, since a CD is read-only once it has been burned by CD recording software no changes persist through reboots. So, if you download a file or make some application settings they will disappear when you shut-down. This is both good and bad – on the plus side, if you screw up anything or get a virus, the system will be restored once you have restarted it. But not being able to save stuff is of course inconvenient in some cases. If you find that frustrating you might want to run __INCOGNITO__ from and USB memory stick instead, making it into a LiveUSB, which is writeable and where it is possible to make it so that the changes persist through reboots. You can read more about this and its implications <a href="#usb">later</a> in this walkthrough.</p>

-<p>The "Anonymous Email" entry is pretty interesting. Pressing the envelope icon will bring forth a dialogue which makes it possible to send anonymous email. Besides first routing the mail through the Tor network, it will also be routed through the <a href="http://en.wikipedia.org/wiki/Mixminion";>Mixminion</a> network, which offers even greater anonymity than the Tor network, at least in theory. In practice the Mixminion network is a bit too small for offering much anonymity, but that extra layer of indirection will probably not hurt. Also, notice that this is one-way only, so the recipient cannot answer unless you specify a response address in the message. Of course, that could defeat the whole purpose of sending email anonymously. If you want the recipient to be able to answer you by attaching a response address you should consider encrypting the message. TorK does not offer an interface to GnuPG, who will have to do that manually, perhaps with PGP (<a href="#kpgp">KPGP</a> is an easy alternative for this).</p>

tab:</p>
<p align=center><a href="img/tork-network.png"><img src="img/tork-network.png" width=400 height=325 border=0></a></p>
-<p>In here, all the Tor nodes in the Tor network are listed, as are all your circuits and connections that go through the Tor network. All this requires a bit of technical knowledge of how Tor works in order to understand and use, but it is not strictly necessary. From the connection listing it should at least be relatively easy for you to see which exit node and country it appears your connections come from.</p>

From the connection listing it should at least be relatively easy for you to see which exit node and country it appears your connections come from.</p>
<p>One very useful thing when working with Tor is the following option, found in the TorK menu that you get by right-clicking its systray icon:</p>
<p align=center><a href="img/tork-menu.png"><img src="img/tork-menu.png" width=182 height=98 border=0></a></p>
-<p>The selected "Change Identity" option will tear down all you current circuits and build new ones which means that the computers you route your Internet traffic through will be changed to some others. This is very useful if you experience bad performance or even time-outs accessing some Internet resource as you might have better luck with the new circuits that are built. Also, if you ever want to make sure that one thing you are doing will not be linkable to the next thing you are going to do you should use this feature.</p>

Also, if you ever want to make sure that one thing you are doing will not be linkable to the next thing you are going to do you should use this feature.</p>
-<p>TorK also makes it easy to use some of the Tor Networks more advanced features. For example, if you switch back to the "Anonymize" tab you will find an entry for "Anonymous Websites and Web Services" which allows you to set up <a href="http://www.torproject.org/hidden-services.html";>hidden services</a> by clicking its icon (an English style police hat). Another feature that might be useful when you are using __INCOGNITO__ from a restrictive network can be found in "Settings menu -> Configure TorK -> Firewall/Censor evasion". This makes it possible to use <a href="https://www.torproject.org/bridges.html";>bridges</a> as entry points to the Tor network in order to circumvent censorship systems trying to block your access to the Tor network.</p>

-<p>Lastly TorK will assist you setting up yourself as a Tor server, helping out the Tor Network by relaying other people's traffic. You also have the possibility to act as an exit node, which means that other Tor users' traffic will exit in the clear from your computer. You should really think through if you want to do the latter (act as an exit node) as your ISP might start sending you complaints for other people's file sharing traffic that happens to exit from you, and potentially even worse things that might attract the attention of the police. But simply relaying traffic is completely safe and will only cost you some bandwidth (how much can be configured). However, at the same time you will get more anonymity – it will be impossible for eavesdroppers to distinguish the Tor traffic you are relaying from that you are generating for your own Tor usage use (while web browsing etc.). So if you have bandwidth to spare, you might want to consider doing this.</p>

-<p>In order to succeed with setting up a relay you might have to do something about your firewall or router if you have one, like enable port-forwarding for ports 9001 and 9030 – if you do not know what this is or how to do it you should either look it up on your favourite search engine or simply skip it. The next step would be to actually enable it in TorK, which only requires a few clicks. First press the button with a plus icon called "More options" which will make a few more buttons appear.

+<p>In order to succeed with setting up a relay you might have to do something about your firewall or router if you have one, like enable port-forwarding for ports 9001 and 9030 – if you do not know what this is or how to do it you should either look it up on with favourite search engine or simply skip it. The next step would be to actually enable it in TorK, which only requires a few clicks. First press the button with a plus icon called "More options" which will make a few more buttons and options appear. One of them says "Run as a server" when you hover the mouse cursor above it. Simply click it and choose "Relay Tor traffic" and follow the instructions. After that you will just have to wait for half an hour or so before the connections start rushing in. Due to this delay and some technical reasons it is best if you only act as a Tor server if you <a href="#usb">run from USB</a> as that will speed things up a little next time and also spare you of the time taken to set-up the server.</p>

This address is actually used to address your computer on the <em>local</em> network, but it will <em>never</em> get out on the Internet so people can <em>not</em> use it to trace you. However, other computers on the network could log it which then would provide proof that your computer have been connected to it. As such, this is not a concern if you are using __INCOGNITO__ with your home Internet connection as that can be linked to you any way, but if you are connecting your computer to an untrusted, public wireless network you might consider enabling it.

<p>Running __INCOGNITO__ from a CD has its virtues but it certainly also have its limitations. While CDs are portable they usually do not fit in your pocket in a comfortable manner. But a USB memory stick certainly fits any pocket or your key ring. In addition, CDs are read-only and thus no data can be saved to them, but that is, again, not the case with USB memory sticks. However, storing sensitive data on a USB memory stick could be dangerous if it got into the wrong hands. Similarly, if we get a virus or manages to damage the system in other ways, the system is tainted or unusable from that point and all consecutive boots, either with or without your knowledge. Clearly that is not good.</p>

Well, when running from a USB memory stick, the system is still set up to not be writeable – it is loaded to RAM so any changes stay only there and are not persistent.

-<p>__INCOGNITO__ works very well in <a href="">VMWare</a> with the following <a href="http://files1.cjb.net/incognito/incognito-vmware-1.0.zip";>VMWare Virtual Appliance</a> (<a href="http://files1.cjb.net/incognito/incognito-vmware-1.0.zip.asc";>signature</a>) devised by the __INCOGNITO__ developers. Simply unzip the file and follow the provided instructions in <code>README.txt</code> which is provided with the archive. The free (<a href="http://en.wikipedia.org/wiki/Gratis_versus_Libre";>as in beer</a>) <a href="http://www.vmware.com/products/player/";>VMWare Player</a> might be useful for this. In order to get good performance you will probably need administrator privileges when you install VMWare. Note that VMWare is closed source, so it might be hard to determine of it does anything that is bad for anonymity, although it is unlikely.</p>

<h4>VirtualBox</h4>
-<p>Unfortunately __INCOGNITO__ does not work perfectly in <a href="http://virtualbox.org";>VirtualBox</a> yet, but we are working on it. That is not to say it does not work at all, just that you will have to tweak it a little. All will go well until the X server is starting, as it will fail due to problems with the auto-detected graphics driver. For some reason the correct driver is not detected, so when you get to the console you will have to change the graphics driver used in <code>/etc/X11/xorg.cong</code> to "vboxvideo", and then run the following command:</p>

Of course, it is unacceptable to have to do this procedure at every startup (but this can be mitigated by making a snapshot of the VM state when you have fixed this), so this is only for testing purposes. Hopefully this will be fixed in a future release.</p>
<h3><a name="windows"></a>Running __INCOGNITO__ from within Microsoft Windows</h3>
-<p>Thanks to QEMU, presented <a href="#vm">above</a>, __INCOGNITO__ can be run within Microsoft Windows without the need to restart the computer. QEMU ships with __INCOGNITO__, and is set up so you only have to insert the media when Windows is running and a menu should appear with the option to start __INCOGNITO__ through it. This is especially useful when you are using a computer you are not allowed to shut-down, which can be the case for public computers in certain Internet cafés or libraries. Also, for some some general remarks on QEMU and __INCOGNITO__ as well as some security concerns about this mode of operation, see the above section on <a href="#vm">__INCOGNITO__ and Virtualization</a>.</p>

<h2><a name="conclusion"></a>Conclusion</h2>
-<p>By offering you __INCOGNITO__ we hope that you have the technological means to stay anonymous on the Internet. However, we want to emphasize that staying anonymous is <em>not</em> only a technological problem – there is no tool, including __INCOGNITO__ and Tor, that will magically make you anonymous on the Internet. You will have to behave as well. While deep technical knowledge of the architecture of the Internet, cryptology and traffic analysis techniques, and the applications used certainly can help you with that (mainly by knowing what <em>not</em> to do), we believe that some good ol' fashioned common sense and caution will be enough in most cases. Among other things, that includes:

<ul>
- <li>Choosing good passwords and not writing them down in stupid places.
+ <li>Choosing good passwords and not writing them down in unprotected places.
<li>Using end-to-end encryption whenever possible.
<li>Not trusting everyone and everything but being a bit suspicious in general.

+ <li>Making an effort for properly authenticating with everyone you are communicating with.
<li>Being very careful when dealing with identifying information such as name, whereabouts, the local time and so on. Any such piece of information that you leak will help a would be adversary to get closer to you.
</ul>
-<p>Also, please try to follow the instructions given by security tools as much to the letter as possible. There are situations where one can be creative or improvise solutions, but you should really try to learn when that is appropriate before you do it. For instance, when using PGP encryption you are often asked to verify the authenticity of any new public key that you have just got. If you do not do this it is possible that you are using a compromised key sent by an attacker in a <a href="http://en.wikipedia.org/wiki/Man_in_the_middle_attack";>man-in-the-middle attack</a>. Usually the authentication works by presenting you with the key's so called fingerprint, which is a unique identifier for that key. Verification should then be done by asking the other party to send you the fingerprint through some safe channel, which could be anything from telling it by telephone or VoiP (which is hard for an attacker to manipulate on the fly) or even face-to-face, and then making sure that they are the same. Assuming the channel is safe the key sent by the other party and the one stamped on the key should be identical, otherwise something is wrong.</p>

For instance, when using PGP encryption you are often asked to verify the authenticity of any new public key that you have just got.

Usually the authentication works by presenting you with the key's so called fingerprint, which is a unique identifier for that key that cannot be faked. Verification should then be done by asking you friend to send you the fingerprint through some safe channel, which could be anything from telling it by telephone or VoiP (which is hard for an attacker to manipulate on the fly) or even face-to-face (but hen you can exchange the actual keys securely instead), and then making sure that they are the same. Assuming the channel is safe the fingerprint sent by your friend and the one you get from the key should be identical, otherwise something is wrong.</p>
-<p>The above methods of fingerprint verification are of course not always possible, but here is one of those places you can be creative. For example, you could send the fingerprint hidden in an innocent looking image by some means, although this is admittedly not bulletproof. You could make this method safer by first sending the picture to your unknowing recipient and telling him or her how the fingerprint is hidden when you know that it has been received. Additionally, these kinds of tricky exchanges are always better to make over interactive communication channels such as IRC or with instant messaging since that will decrease the window of opportunity for any eavesdropper to interfere. Email is not very suitable as delays are long which gives the attacker ample time to act. An alternative authentication method to fingerprints, used by OTR, is to simply ask both parties of a shared secret that both should know. In this case, do not choose just anything – if someone is watching you they probably know which high school you went to, the size of your shoes and similar facts.</p>

<p>This is probably the place where we are expected to wish you good luck, but we will not. Relying on luck simply is not good practice in these situations. Stay cool and be smart! Thanks for you time!</p>
