The situation is: I don‘t want to able to surf certain websites out of distraction of boredom, while I am in the University, studying. My idea is:   Create a sudo-password which is to complex to memorize it, write in somewhere and leave it at home when I go to the University. Create a user-account with restrictions, on the websites, which can be visited. Study without distraction.

I bought my kids a PC and installed 12.04 (Unity) on it.  The bottom line is, I want my children to use the computer unsupervised while I have confidence they cannot access anything inappropriate.  What I have looked at:  I was looking at Scrubit a tool which allows me configure my wifi router to block content and this solution would also protect my other PC and mobile devices.  This may be overkill as I just want the solution to work on one PC.    I also did some Google searches and came across the application called .  My experience of OSS is that the best solutions frequently never appear first on a Google search list and in this case I need to trust the methods therefore my question is very specific.   I want to leverage your knowledge and experience to understand What is the best way to restrict adult content on 12.04 LTS as this is important to me.  It maybe a combination of things so please don't answer this question "try this or that", then give me some PPA unless you can share your experience of how good it is and of course if there are any constraints.

I just powerwashed (that's a factory reset on chromebooks) my computer so that it would be be 'brand new,' however now I don't have sudo access anymore. I used to not need a password to use sudo, however now a password is required and I have no idea what it is. I tried my login password, however that didn't work. Any advice?

How does sudo work internally? How is it possible that it can become root without having the root password, unlike su? What syscalls, etc. are involved in the process? Is it not a gaping security hole in Linux (e.g. why couldn't I compile a heavily-patched sudo that just did whatever regular sudo did, but didn't ask for the unprivileged user's password)?  I have read . I have also read  but despite the title, they mainly deal with the differences between su and sudo.

I would like to make my Chrome/Opera to save login, password data without asking about it. It everytime asks if I want to save a password, but I want it to do this without any popups over time on different websites. Any ideas?

I am a user of Ubuntu with not much experience and I have been using sudo.  What does sudo !! do and how?

On my personal machine, I often type sudo in front of certain commands in order to accomplish administrative tasks.  I had hoped to avoid doing this throughout the day, by typing su root and providing the same password I usually do for sudo.  However, the two passwords are not the same(I don't know how to log in to su root).  Is running a command with sudo different than logging in with su root and running the same command?  I think sudo and su root are the same, because when I type sudo whoami, I get root, as opposed to just whoami where I get my user-name.

I'm looking for a good, consistent and easy way to do a report of sudoers permissions for every user and group on the system. For users, I want the report to include permissions granted via group membership.

I am trying to find the correct reason for the stated question. My understanding is that:   sudo needs to read the /etc/sudoers file which is only readable by root, which is why it needs to be set-UID root su is going to create a new shell with a different real and effective UID, and needs to check the password. To check the password, it needs to read /etc/shadow, which is why it needs to be set-UID root. After checking password, it would need to call setuid() on the forked process, and to use an arbitrary UID argument, its parent process must have root as effective UID, so this also makes another reason.   Are the above reasons correct ?

Let's say, I have the following bash script:  #!/bin/bash sudo command1 command2 sudo command3   I don't want to run command2 as root, so I won't run the script itself with sudo. Therefore, as soon as I execute the script, sudo command1 asks for my password. Unfortunately, command2 takes about 2 hours to complete. So the sudo credentials timestamp timed out and when the script reaches sudo command3, I'm prompted for the password again.  I don't want to permanently disable the sudo credentials timestamp timeout altogether as described in  for example. I just want to disable the timeout temporarily, effectively keep the credentials for this one bash session until it ends.

I know I can become root (super user) via the su command but I have to authorize it after entering the commands. Is there a way I can become root and authorize (with password) in one line

Here are my circumstances:   I am running Ubuntu 12.04. I have one user account.   I absolutely hate the password requirement. How do I disable this requirement such that my Linux computer will behave more like Windows in this respect? I do not want to hear that I shouldn't this because it is not secure. This is my desire so the concern of security is effectively null and void.

Is there an ability to not allow sudoers view your folder (only you and root can access folder)?

Is there a way to temporarily suspend history tracking in bash, so as to enter a sort of "incognito" mode? I'm entering stuff into my terminal that I don't want recorded, sensitive financial info.

I have some user accounts in my Ubuntu 10.04 and I want them to login from all over the world and access their data using Internet and of course I want any of my users to be able to access only their own user and to be able to change data.  What should I do? Are there any remote desktop apps?

I'd like to join three ideas into one interesting and sometimes useful feature. There was a question about using multiple passwords earlier this year, but it didn't receive much attention. I'd like to ask the question again after showing an interesting and new way to use the feature. The three original posts I found to be interestingly combined were:        Basically I'd like to login to my account with two passwords and depending on the password I use, I would get a different content in my home directory. In a way I would get a cryptographically hidden account into my system. So the question is, is it possible to allow multiple passwords to log on to Ubuntu/Linux for the same user?

I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?

I was wondering if I use my computer running Ubuntu only for browsing while using the guest account on an unpatched PC logging in to any site I browse - will it be possible to steal any passwords typed into the browser or not?   Can e.g. a harmful web site steal my administrator password for the PC or even the WiFi password?
