    Linux Transferring data from one Linux system to another, do I need to worry about permissions?


    Transferring data from one Linux system to another, do I need to worry about permissions?

    Posted: 12 Dec 2019 01:46 PM PST

    Hello, please forgive the noob question, I have a Linux server here and I need to transfer some data from this server to another server across the country. These are completely unrelated servers, and the usernames and groups on the originating server are completely different from what is on the destination server. I plan to transfer the files by uploading them to a FTP server and having the person on the receiving end download them onto their system.

    Currently the files are owned by a username on the originating server with 755 permissions.

    Will the person on the other end be able to browse these files? How does this work? Will they be able to just grab the files and chown them to their current account and modify the permissions as they see fit? I guess I have never encountered this situation before and do not have a really good idea of how to test this out. thank you!

    Switching from Windows 10 to Linux. Want to clear some doubts

    Posted: 11 Dec 2019 08:02 PM PST

    I've used Linux before in my college and with the help of virtual box on my PC. Now I'm totally switching from slow windows to Linux, mostly Ubuntu.

    Doubts are: 1. Once I've formatted windows and installed Ubuntu, will i be able to access data stored in other drives expect C ?

    1. Can I partition the drive like Windows ?

    2. There are some softwares which are unavailable for Linux, like Google Input Tools (Transliteration software), i searched and found there is a distribution called as Wine which can be used to run windows software on Linux. Is it trustworthy? How can I know whether the software i want to use can be converted into distribution or not?

    3. Same with 'Google Back-up and Sync' and 'One drive'. Which third party clients will you recommend ?

    Noob sentence fr: ignore grammatical mistakes and thanks in advance

    Edit: i got confused between Mint and Wine, corrected.

    Question using Yumi from Linux.

    Posted: 12 Dec 2019 10:15 AM PST

    I'm looking into switching to Yumi for my multiboot USB from E2B. According to the instructions Yumi can be used from Linux with Wine, however creating a persistent file for a live ISO is broken. I'm wondering if I create the drive with Windows with one persistent file, can I add additional ISO's with Linux and Wine later? To clarify I don't expect the ISOs I add later to be persistent, just regular installers or live images.

    Or is there a better option for me? I need to be able to add Windows and Linux images, preferably from Linux but both Windows and Linux would be nice. I've tried MultiSystem but its painfully slow to add new images.

    Locale Settings Unset

    Posted: 12 Dec 2019 01:51 PM PST

    I did a manual install a monthish ago and I believe I failed to properly set my locale at the time and I'm not sure how to fix it. The error message that I've seen the most often and that has the most description comes when I use GNU Stow, although the operation completes successfully regardless:

    perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE="". LC_ALL = (unset), LANG = "en_US.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C") 

    The only thing in /etc/locale.conf is LANG=en_US.UTF-8. I did try adding LC_ALL=en_US.UTF-8 on a whim, but it didn't change anything for me after a reboot. I'm kinda fighting an enemy I can't see in the sense that I apparently don't understand what I'm trying to do well enough to find relevant information online, so any pointers in getting oriented with locales is welcome.

    Here's a possibly goofy question about support.

    Posted: 12 Dec 2019 01:50 PM PST

    I'm a pretty experienced Linux user (I've been using it since the beginning of 2015 and am very comfortable with the terminal) and have experience with CentOS, Fedora, Ubuntu, Debian, and Mint. My question is about support. I have an older HP laptop that was recently given to me by a family member, and it has an AMD A6 processor and 4GB of RAM. I Love Ubuntu, but I loaded Linux Mint XFCE because it's Extremely functional out of the box, and XFCE is extremely light. Should I have any concerns about Linux Mint like dying out? I love that Ubuntu has the backing of an actual company and that it has a lot of business around the world, whereas Mint is supported by volunteers.

    Will it just upgrade from 19.2 to 19.3 or will i need to reinstall Linux mint 19.3 by an USB?

    New to Linux/Raspberry Pi

    Posted: 12 Dec 2019 01:01 PM PST

    My girlfriend got me a Raspberry Pi 3B for my last birthday. I don't know much about Linux or Raspberry Pi in general. So far I've turned it into a RetroPi, but I want to learn how to do more. Does anyone have some resource for people who are completely new to the Linux/RP scene?

    Keyboard autosleep

    Posted: 12 Dec 2019 12:20 PM PST

    Hi!

    Recently I've started using linux as a desktop system (Xubuntu 19.10) and I've noticed that my keyboard (Anne Pro 2) goes into sleep mode after a while. I downloaded the driver from producer site but it seems that not every functionality of this driver works properly under linux (even though it's even packaged for it as a .deb package), that is there is option to enable/disable Auto Sleep but I think that this is not working at all. Basically, the problem here is that leds are working fine but I can't type anything till reconnecting the keyboard to the PC. (same problem on bluetooth connection) Is there any way to prevent keyboard of turning into sleep mode with config files directly from OS?

    Thanks in advice!

    Installing Linux on a new drive...

    Posted: 12 Dec 2019 12:17 PM PST

    I bought a SSD but my laptop only has one SATA slot, so i'm removing the current HDD. I also bought a SATA to USB adapter so i can still use my HD as an external drive. My question is, will i be able to get files back from the HDD through USB given that i have the root password?

    Extra question: should i switch from KDE to XFCE? I don't really care that much about customization.

    Thank you very much for you attention and help!

    Getting VPN to connect on login.

    Posted: 12 Dec 2019 11:42 AM PST

    I'm using xubuntu 19 I believe and cyberghost VPN as VPN client. They have a terminal app that connects using the following command

    sudo cyberghostvpn --server [server name] -- connect

    I have a dedicated IP so will be connecting to same server each time. I want the command to run on startup or login. I don't mind if a prompt shows up asking for admin password but I need the command to be executed automatically.

    Things I have tried: 1. Creating rclocal file in /etc/ with the command minus 'sudo' and setting it to be executable. I believe I tried creating the file both as user and as root. Didn't work. Also, there was no rclocal file in /etc/ to begin with where the forums say it should be. Might be in one of the rc1 rc2 or rc3 files?

    1. Creating xsessionsrc file in home and having the command minus 'sudo' in it

    2. Creating a script file (header #!/bib/bash/) and trying to set a crontab to execute it. Did both sudo crontab -e and just crontab -e.

    Pretty sure I'm just doing something wrong because others seem to have had success running startup jobs with similar methods. Please help. Will answer any other questions in comments. Thanks in advance

    AMDGPU - how to choose RGB Limited?

    Posted: 12 Dec 2019 09:48 AM PST

    Hi, i am currently using an Nvidia GPU with the closed source drivers on my HTPC Xubuntu 19.10 install. In the Nvidia settings i am able to switch between RGB full and limited colorspace. I find RGB limited the best match for my TV and the video content i watch.

    I am considering switching to an AMD GPU in the future and have been searching for instructions on how to switch between colorspaces with the open source AMDGPU driver. I have not been able to find any instructions yet. Does anyone know how to do it?

    Looking for a command-line only installable distro

    Posted: 12 Dec 2019 08:46 AM PST

    Hi everyone,

    I'm trying to find something of a barebones distro that I can install from a USB stick. I'm looking for something that doesn't include a desktop/windowing environment because this is going to be installed on a pretty old laptop with limited space and resources (want to say it's a Pentium dual-core CPU with 2 GB RAM and a 32 GB hard drive). This is going to be used just for SSH/SFTP, some Python programming and just generally learning more about Linux under the hood on a system I care only slightly about making a mess of.

    I know I can probably install something like Ubuntu with xfce and boot into the command line directly via config, but if possible I want to avoid installing any desktop environment at all. Is there any distro that will let me do this? I thought about Ubuntu Server, would that be a good choice?

    When adding new drives to an existing MDADM array, do I count the spare?

    Posted: 12 Dec 2019 08:29 AM PST

    I have an existing MDADM RAID 6 array. 12 active devices and the 13th (/dev/sdm) is a hot spare. I'm getting ready to add 2 more drives at once (done it before so I know it's OK to grow with multiple drives). When I add the 2 extra drives, is it --raid-devices=14 (if I don't count the spare) or --raid-devices=15 (because I have to count the spare?)

    Retroactive install script generation

    Posted: 12 Dec 2019 08:17 AM PST

    After taking the dive and installing pop_os onto my daily laptop and customizing it, I've heard about users who have created scripts to do all of that for them in the case when they need to reinstall or migrate machines or what have you. Is there a way to detect the differences between the stock os and what I've done (apt, gnome extensions, download tars and unzip/install manually, pop store) and place that into a script? Or at least just make a list of things for me to remember to install at a later date. I believe windows will do this when you "refresh" the install by placing an html doc on the desktop housing a list of programs in the default program files. For the time being, I don't expect to switch from gnome/ubuntu/pop_os, so solutions can be specific to those de and distros.

    Win10 user wants to switch and needs a lightweight distro for his T440p

    Posted: 12 Dec 2019 04:10 AM PST

    I am a long-time windows user, who recently bought his first laptop. I want to use a lightweight OS on it, so it will be reliable and quick. Win10 already runs quite well on this machine, but I am wondering how well a Linux distro will run. (...and I always wanted to try another OS.)

    My everyday tasks are the following: Browsing the web (mainly reddit, youtube, twitch, twitter etc.), playing games via emulator (mainly Super Smash Bros. Melee via Faster Melee, which is a version of the Dolphin Emulator.) and playing other lighter games (CS:GO, LoL, older titles and so on.)

    My specs are the following: Intel i5-4300M, 16GB DDR3 RAM, Nvidia GT 730M, 240GB SSD. I have not changed the screen, touchpad or the keyboard. Apart from the RAM and SSD everything should be stock. Don't know for sure, because I bought it used. Besides CS:GO, LoL and other games, which require an internet connection, I do not intend to use the dGPU and stick to the iGPU.

    The distro should not be overwhelmingly complex. Keep in mind, that I have never used anything else besides Win. I know a little bit of tech and software, but not nearly as much as the average linux geek. I want it to feel snappy and push through my everyday tasks with ease. I hope to get a performance gain in Melee, since this may be the most demanding task I regularly throw at it.

    Is it possible to create a user account with read only permissions?

    Posted: 12 Dec 2019 06:13 AM PST

    Hello all,

    I was wondering if I can add a new user and set the user up with read only permission. So that when a user logs in to that account they can one read but not write.

    Thanks for the help.

    Is there a way to install KDE Plasma on CentOS 8?

    Posted: 12 Dec 2019 05:32 AM PST

    I've been planning out my migration from Win7 to CentOS and was disappointed to hear that KDE Plasma has been deprecated.

    Is there a workaround to install KDE or can I do the default install with Gnome and then replace it some way? or is Fedora Spins my only option? I wouldn't even mind paying for a RHEL workstation license if I can get KDE out of the box.

    Can I setup RAID1 on two hard drives on my laptop while first one being already populated with data and I don't want to lose any data?

    Posted: 12 Dec 2019 03:48 AM PST

    I just added an extra 1TB HDD, my main hard disk shows Self Disk Check failed and sometimes loses some random data. I am thinking about setting up RAID1 so that I could protect myself from data loss.

    I dont know how to setup RAID at all. Is it even possible with 2 HDD and Is it recommended? Does it improve/reduce performance? Can I setup without the need of formatting all data and setting up new partition table? Help me RAID experts.

    I want to try RAID on a personal laptop. Possible without additional storage devices?

    Posted: 12 Dec 2019 02:06 AM PST

    Hi,

    trying to improve my knowledge of Linux and OS in general. I see that RAID is a thing in server space. I would like to try it for learning purposes but I don't have sophisticated storage devices or expensive machines. So, what are my options? Also, does it make any sense to have RAID on a private laptop or desktop?
