I personally don't use Unity but if you're looking for a way to hide traces of certain, erm, "activities", you could create another user account that was dedicated to that activity which would have its own Unity cache and settings, so you could go wild and nobody ever need know. So let's say you have a passion for painting Warhammer 40,000 characters. ...

One is a Ubuntu GeoIP Provider and the others are scopes. To list what services are connecting to IP addresses try sudo lsof -n -P -i +c 15 Ubuntu GeoIp Provider I don't know what the geoip provider connection is for, what it does, or why we've been told we need it. I can find little information about it, and any attempted explanations about what it is ...

They are proxying through productsearch.ubuntu.com with HTTPS encryption (though there's still a a heated bug discussion over whether the search should be included at all). Unfortunately, while no personally identifying information is sent to Amazon, the privacy policy for Ubuntu sharing information about proxied searches is still unclear. Also, there are ...

As of 2014-02-13, The Tor Project's Ubuntu installation page says: "You'll need to set up our package repository before you can fetch Tor. First, you need to figure out the name of your distribution. A quick command to run is lsb_release -c or cat /etc/debian_version. If in doubt about your Debian version, check the Debian website. For Ubuntu, ask ...

A Public folder exists in your Home directory (/home/user) for sharing files with other users. If an other user wants to get access to this Public folder, the execute bit for the world should be set on the Home directory. If you do not need to allow others to access your home folder (other humans or users like www-data for a webserver), you'll be fine with ...

Add this line: deb http://deb.torproject.org/torproject.org <DISTRIBUTION> main to the /etc/apt/sources.list file, using sudo nano /etc/apt/sources.list. Also, I find it easier to just download the tor browser bundle and unpack it. You get manual updates, but it informs you when there's a new version.

The GUI tools ignore accounts with uid < 1000, which are reserved for system accounts. Give the account an unused uid in that range and it won't show up in the gui tools. Short of patching in a backdoor into the login program though, you can't hide it from the command line tools or direct inspection of /etc/passwd.

Since any user needs to have a password entry in /etc/passwd the answer is No. Anyone with root access can see the contents of the file and therefore know about your user. Even if you use directory services such as ldap, the user has to be registered somewhere. When it comes to hiding from other desktop users, you can do some things to make it harder. ...

Using this extensive knowledge, the performance of the system can be improved considerably.

I do not believe Amazon will see every query in its original state since these queries are sent to productsearch.ubuntu.com and then continue on so your ip address is not reaching Amazon's API. However the other concern is how does Canonical handle these queries since they get them in the original form and have no issued a privacy policy explaining whether ...

Uh, those are not Amazon results but Ubuntu Software Centre results. They are not live online results - but use data obtained by updating the apt database (which you would need to do for installing software anyway). No third party is involved. To disable it, see How to remove the Ubuntu Software Center Suggestions from the Dash.

Is it used for tracking? No; GeoClue itself does not contact external services for the reason of providing your location, but rather only provides an API for ubuntu applications to use to find out where you are. If you are in doubt that GeoClue is providing location data to a third party for the purpose of surveillance, you can examine the source code ...

According to an Ubuntuforms.org staff member, it is to make it easier to share files between new users. You can change the permission to either 700 or 750 if you don't want the files readable and executable by others. Command is: chmod 750 $HOME Note: Ubuntu default is 755

We don't generally track user behaviour. We do have some statistical metrics to understand how people use our software, like how many shares do people create a day, how many public files, how much space do people use on average, etc. This is to help us understand how people use our product and how to improve it. We don't track individual users at all, we ...

You can have shell users without a home directory: useradd --no-create-home new_username But this probably won't cut it if you need to be able to log in with this user. As Carsten says, there's always going to be a trail back to the user at some point because the system needs to authenticate them. If you're just trying to hide somebody from the login ...

Dash search terms are not sent to Amazon directly. They're sent to Canonical, which then sends them to Amazon. That means Amazon doesn't get your IP. However, as of the current implementation, thumbnail requests are directly sent to Amazon. So Amazon does get your IP in the end. More details: ...

Personally, I think people generally over-rate the concern for preserving "private" data when it comes to reporting crash data and such. But, there is a good reason for reviewing the data that you send to application developers. It really would depend on who you are submitting these logs to and for what purpose. Generally, as a first pass, personally, I ...
