    How to Utilize Linux to Prepare Me for the Cyber Security World

    Posted: 30 Apr 2018 07:34 AM PDT

    Hey everyone! I've been using windows for nearly 15 years, but everything in the Cyber Security world is Linux-based. So my question is where to start in building a solid foundation for myself later on? I have no idea where to start with using Linux, or how to use it for particular purposes. I need to become proficient in Linux so I can branch out into the Admin or PenTest worlds, so I figured this thread is the best place to start for initial guidance. Any and all starting information is helpful, and I'll be answering and asking questions along the way.

    Want to start Contributing to Unix,tried a bit but suck at it,Looking for advice on books,resources to be better x-post /r/linux

    Posted: 30 Apr 2018 05:09 AM PDT

    Been using Linux since junior high,and i would love to contribute to Unix rather anything Unix based not just limited to linux. Know C at a intermediate level so

    i gave it a shot found a project on a certain bsd distro ,contacted the person incharge,the mailing list set it up did stuff.But couldn't grasp the code.I even read up on the file system i was supposed to fix,the journaling modes how it works etc but unable to understand what's going on in certain parts of it. That's when i realised i should maybe start from the bottom before tackling something this big even though it was listed a easy project.

    I am looking for books,papers that i could read so that i become better and one day be able to send a patch.I have taken the Operating systems course in Univ,read galvin but that does not cut it. At this point i do feel a bit lost and question if i am bit too late to late at 21.

    Focus (Transparency n' Blur), Bar Alternatives and Bash-it Themes

    Posted: 30 Apr 2018 01:10 PM PDT

    Hi, I've got some questions:

    1. When the OS boots up i3-gaps creates 4 workspaces, each with some programs. How can I make one program in each workspace be the dafault to get focus.

    I've seen a solution but that only made 1 program in only 1 workspace get focus and it would switch to that workspace automaticly.

    1. How can i replicate the transparency and blur of this, a slight transparency and blur without the blur afecting the letters? Do note that I don't want blur in my browser (qutebrowser).

    Also, how do these type of guys know which program they're using, like, there's no focus indicator.

    How can I make my focus (indicator) window make the window transparent and removes the blur?

    1. Is there alternatives to bars like i3blocks? Not talking about other bars, I mean another way of showing info.

    2. How can I remove the bash-it default theme?

    trouble locating python

    Posted: 30 Apr 2018 10:39 AM PDT

    Good evening Reddit.

    So i am pretty new to Linux, using Lubuntu 18.04 at the moment and I am working with python.

    So I don't know if I should post it here or in r/learnpython

    However I am following this guide on how to create an twitter bot and in the guide I was asked to install an module called "tweepy", so I installed it through the terminal. as ordered and the installation (as far as I can tell) went successfully since no errors appeared.

    I can also see through a pip command list, that it is indeed installed on the machine.

    However I wanted to see it for myself manually, so i used the which python3.6 command and it said that it was located in /usr/bin/python3.6 however when I look around there is absolutely no folder named that.

    I am totally lost here.

    Ps. Python was installed by defualt, however I had to manually install the python idle.

    Best regards.

    Low Resolution on VM

    Posted: 30 Apr 2018 11:09 AM PDT

    This is my first time trying Linux. I have just installed Xubuntu with Guest Additions in a Virtualbox instance. My hardware is a 2014 Macbook Pro with Retina. Everything appears to be fine, however the full screen resolution defaults to 1280x800. The host OS runs at 2560x1600. When I raise the resolution, I can only see the upper-left portion of the screen.

    I have already consulted the Arch Wiki, but the advice is regarding how to make the software fit the higher resolution, instead of my problem.

    Thank you for any help you can provide.

    Help a battle brother play Battle Brothers please!

    Posted: 30 Apr 2018 02:13 PM PDT

    Hello,

    So I have an Acer Chromebook 15 and I've installed GalliumOS using Chrx so that it's installed alongside ChromeOS. Everything works fine I've been using the laptop for mostly development.

    Lately I became hooked on Battle Brothers which doesn't have Linux support. I have Wine 3.0 installed and have steam installed and working. When I try to launch Battle Brothers it tells me that my video card doesn't have a framebuffer and tells me to update my driver.

    After a lot of googling I found that people said to put -gl30 on the launch parameters of the game on Steam so I did. Same error.

    I can't remember now but I found some post about how to update my driver and followed that. However, when I restarted my computer and logged back in my task bar was completely white, same with terminal. I got frustrated and decided screw it and just reinstalled linux using chrx. I'm up to the same point again.

    I have the game installed, steam working, programming stuff installed. I've tried and tried to find out how to update my gpu drivers for linux (Processor is intel celeron dual-core 3205u) and I can't find anything besides using some Intel Linux Graphics Update tool that apparently got canned a couple months ago.

    If anyone has any idea on how to update my driver so that I could play this game I would greatly appreciate it!

    My Ubuntu GNOME keeps crashing...

    Posted: 30 Apr 2018 01:53 PM PDT

    So, I installed Ubuntu GNOME because I had some problems installing Fedora, but anyways, for some reason it crashes from time to time, it is still very usable something like twice a day it crashes and it is very annoying, I even had to learn the command (alt +printsc + R + E + I + S + U +B).

    So, I thought it could be firefox, it isn't, sometimes it crashes only with the browser open (vivaldi or firefox)

    Is Ubuntu GNOME instable like that or is there something wrong?

    Also I made ctrl + alt +del attached to the system monitor but when it crashes it doesn't even open

    I have a ryzen 7 + 16GB RAM and RX560 (Downloaded the driver from the AMD website) with dual boot with WIN10

    Linux issues in Ubuntu based distros and Manjaro, recommend why or a distro that would work?

    Posted: 30 Apr 2018 01:47 PM PDT

    Hi Guys,

    So long story short, windows crapped the bed with a boot error and nothing I've found has been able to fix it. I thought as a hail-mary, maybe if I reinstalled linux I could bypass the windows boot manager and let grub boot it (I don't think it works that way, but thought I'd try). I say reinstall linux because I had installed linux when I first got the computer a year ago to dual boot with windows. However, I had issues with it (I can't remember what exactly), so to be able to use windows I had to get windows to reinstall it's boot manager, leaving me no way to boot into linux (even if I could get it working). Anyway, with all of the linux live USBs I created, they all start up fine but freeze when I click shut down or restart (ubuntu based and Manjaro). I thought it was maybe just a Live disc issue, so I installed them anyway. Here's what happened:

    - Xubuntu- installed it to a 2nd hard drive, with the bootloader to the first hard drive. Grub gave an error, and goes into grub rescue. I have no idea how to use that so I just shut it down and tried something else. during install, it did find windows and gave option to install alongside it, but I did the 'something else' so I could custom locate it.

    - Linux mint- froze during install, had to hard shut down. Installed to first hard drive partition that I had from when I first got the computer. Didn't see windows but saw xubuntu.

    - Manjaro XFCA- I erased mint and installed. It didn't see windows, just xubuntu. installed ok and grub worked (gave option for manjaro and xubuntu). however, when I try to boot either distro, they both freeze after logging in.

    It seems my computer (MSI GR72VR, I7 7700HQ, GTX1060, 16gb ram) doesn't like linux. So, does anyone have ideas why I get all the issues above (freezing of live USBs for various distros, grub issues with ubuntu based, freezing after logging in)? Is it hardware? software? drivers?Am I doing it wrong?

    I plan to wipe the hard drive, install windows, then install a new linux distro if I can find one that will work.

    Help w/error message when decompressing files

    Posted: 30 Apr 2018 01:23 PM PDT

    I'm doing an assignment for school (baby bioinformatics) and need to decompress files within a virtual machine. I am using the gunzip filename* command and getting "unknown suffix--ignored" response and I'm not sure why or what else I can do to decompress these (.fastq) files. Also tried to "force gunzip" which got me the same response. I'm on a Mac el Capitan 10.11.6. Last week was my first exposure to Linux so I am very aware that I have no idea what I'm doing or saying. Appreciate any help!

    What is the smallest, lightest distro for a Wyse Z90D7?

    Posted: 30 Apr 2018 01:02 PM PDT

    I have a thin client (Wyse Z90D7) with 2GB RAM and a 4GB hard disk. I would like to install Kodi since the client has a slightly powerful AMD Radeon HD 6320 graphics card to play 1080p content off an external 4TB drive. What's the smallest, lightest and fastest distro I can install on this thing?

    Help me with GParted

    Posted: 30 Apr 2018 12:59 PM PDT

    I have Ubuntu on sda5, and Manjaro on sda7, I need to remove Ubuntu completely and extend Manjaro's /home to fill up the free space, wouldn't this have a risk of losing or corrupting data in Manjaro because it'd move all data to the beginning of the newly extended area? I am afraid it would do so and can not risk losing some important data or breaking Manjaro's setup

    Installed Linux Mint alongside Windows 10 yesterday. Linux Mint doesn't detect my speakers. Can anyone help?

    Posted: 30 Apr 2018 11:42 AM PDT

    So I'm dual-booting Linux Mint 18.3 Cinnamon (Version 3.6.7) 64-bit and Windows 10. It's going fine but I can't get Mint to actually recognise my speakers. It works totally fine with headphones, and the speakers work properly on Windows.

    I'm using Logitech Z323 speakers which are plugged into the green 3.5mm jack in the back of my motherboard as per the manual for the speakers (I don't know shit about that sort of thing).

    In the "Sound" settings, I have these two options.

    Headphones works alright, but there's no sound from the other one.

    Does anyone know what I could do to get this working?

    Thanks!

    EDIT: My specs:

    • i5 4690k
    • GTX 970
    • 8GB DDR3 RAM
    • Asus Z97-AR Mobo
    • Crucial 256GB SSD

    Dell XPS upgrade to 18.04

    Posted: 30 Apr 2018 06:26 AM PDT

    I am interesting in moving to Ubuntu18.04 on my Dell XPS. Is this recommended? I am worried about the driver support from Dell and I don't want to install a new LTS if it will impair any of the features that are currently working on the 16.04 version.

    I can't install any distribution of linux

    Posted: 30 Apr 2018 10:06 AM PDT

    A week ago, I wanted to install Kali linux, boots well and no error. When I want to login, it freezes to the grey screen and I can't move the mouse but I can do ctrl+alt+f4, can't login and says this error:

    CPU0 stuck for 22s!

    I though it was a bad kali linux iso, and I've tried Ubuntu, it boots well and I can log in, but it freezes 5 to 10 seconds after I login. I want to install any linux distribution to learn a little about internet security.

    Specs of my laptop: Cpu:Intel core i5 7300HQ Gpu:Nvidia GTX 1050 Ram: 8GB ddr4

    PD: Sorry for my bad english XD.

    Inconsistent reboot - Ubuntu Budgie on new PC

    Posted: 30 Apr 2018 03:01 AM PDT

    I recently built my first PC (AMD 5 2400G APU with Radeon Vega graphics). I had trouble installing several flavors (Fedora and Solus) due to some issues before Ubuntu finally installed.

    However, my computer doesn't restart correctly when I try the restart option on power down. It shows the mobo splash screen and then goes blank. Hard reboot (turning power switch off and on) works to restart the machine but I'm worried this will affect the hard disk.

    Any thoughts on what I could do to fix this?

    Somehow I screwed up my ubuntu 18.04 "additional drivers" tab in the Software and Updates app. I tried to go to Nouveau drivers to test spin wayland and when that didn't work I went back to try and switch back to nvidia drivers and ended up with this "manual drivers..." and other options grayed out: https://i.imgur.com/7JrdQRQ.png

    Dual booting win10 and Linux:Stuck with partitioning

    So I'm using a win10 laptop with STANDARD BIOS and am stuck with the partitioning part. I am following this guide but can't get my head around it: http://dailylinuxuser.com/2015/11/how-to-install-ubuntu-linux-alongside_8.html The guide mentions that you can't go ahead with already 4 primary partitions and you'd wanna delete one of em.I'm afraid I might mess something up.Is there any way around it?Any help would be highly appreciated! Thanks.

    Any good guides to move from Mac to Linux? What about content?

    Posted: 30 Apr 2018 05:41 AM PDT

    The family mac mini--the one with all the videos, photos, and music on it--is slowly dying. I'm tempted to get a small desktop to run Ubuntu for the family--or get a NAS for all of us to use and back up to separately (my wife has a windows laptop, I have one running Mint and my daughter has a school chromebook). We still have an Apple Tv, but most of our DRM'd content from the last 15 years is on the mini. Any thoughts to what I should do without losing my questionable music/video purchases from years past? I'm a home networking noob, in general, so would that be a decent option? Frankly, I don't won't anything too finicky (although in the last couple of years my Apple products no longer "just work" as well as they used to). Thanks!

    Partition locations, swap and home

    Posted: 30 Apr 2018 05:12 AM PDT

    I'm in the process of moving from windows 10 to Linux but I need to keep windows around for my wife and a few other things. To that end, I'm going to end up with partitions.

    I have a main ssd 500gb with windows and some programs, a traditional drive for storage, and an older ssd 100 gb which I actually keep my windows swap file on. That got me to thinking, could I also put the Linux swap on there with its own partition? How about the "home" part? Is that actually its own partition or can it be lumped in with swap?

    Mainly I have no other use for the space on the small ssd and don't want to give up too much space on my main ssd. Will this work out or is it a bad idea? Maybe just put the swap on the small ssd?

    Thank you in advance

    Completely removing an appimage and all of it's data?

    Posted: 30 Apr 2018 04:46 AM PDT

    So I recently decided to give Standard Notes a try on Ubuntu. The download consists of an appimage which becomes executable after running chmod u+x. I've decided I no longer want it on my system and the only related file is the appimage file which I have deleted. I've installed the program again and found that after launching the new appimage, my data is still present from the previous download.

    What do I have to remove in order to completely wipe it from my system?
