    Resize Partition

    Posted: 29 Aug 2019 08:22 AM PDT

    I'm totally new to linux world ... sorry if the question sounds stupid

    I'm playing around with ArchLinux on a VM. Shortly after I created the 3GB root partition using cfdisk, I found that I want to resize it to a bigger size like 5GB. I've expanded the virtual disk. as you can see, I have free space of 9.5GB on the disk, but it seemed that I can only expand the /dev/sda4 disk but not the /dev/sda3. I think it's coz of the start/end number which doesn't allow me to insert free space in between.

    I might have complete wrong concept on this... or perhaps I should create the LVM in the first place instead of doing it this way?

    Any input is much appreciated.

    Unable to boot void linux live usb

    Posted: 29 Aug 2019 08:23 AM PDT

    Hey there, recently i tried to install void linux on my Acer Nitro 5 AN515-42. Sadly ive been unable to do so because when ever I try to boot from the live usb I get the error messages seen in image one. When I searched for a way to solve this issue, i found multiple posts stating i should add acpi=off to the boot parameters, and that i should try to disable amd iommu in the bios, doing so ,however, made the error in image two occur. I also tried to find a solution for this issue for multiple weeks with no success, which is the reason Im writing this post now. Ive almost given up on installing linux at this point.

    I hope someone will be able to help me here.

    Pages handled differently in Word and Libre Office Writer

    Posted: 29 Aug 2019 08:20 AM PDT

    This has been driving me up the wall for the past 3 hours. I started out an essay in Microsoft word on my pc, and ended a paragraph a little short of a page end. I wanted to start the next paragraph on the next page, so I pressed enter ~3 times to skip ahead and start the next paragraph. I saved the file and wanted to work on my Linux (mint cinnamon 19.1) laptop, so I transferred the file over and opened it, but the line break has not been respected. The second paragraph starts on the same page. The lines skipped are same in number, but it hasn't shifted the page over. What can I do to correct this? Thanks in advance and I apologise for the horrific wording. (Pun not intended)

    Edit : I also tried OnlyOffice, with the same result. I also tried saving as doc instead of docx on the windows machine, but this doesn't seem to help either.

    How do I send all traffic from one interface to a second interface?

    Posted: 29 Aug 2019 10:06 AM PDT

    I have two interfaces on Ubuntu. One is ens192, and one is ens224

    ens 192 is set to 172.21.10.250/24 with a gateway of 172.21.10.1

    ens 224 is set to 172.21.253.50/24 with a gateway of 172.21.253.10

    What I am trying to do is make any traffic that hits ens 224 go to ens 192, which would send it out the gateway of 172.21.10.1 according to my understanding

    I have tried to do this:

    used nano to open /etc/sysctl.conf and uncomment net.ipv4.ip_forward = 1 Then execute $ sudo sysctl -p Add the following rules to iptables sudo iptables -t nat -A POSTROUTING --out-interface ens192 -j MASQUERADE sudo iptables -A FORWARD --in-interface ens224 -j ACCEPT

    and rebooted, this doesn't seem to work

    then I tried:

    echo 1 >/proc/sys/net/ipv4/ip_forward iptables -A FORWARD -i ens224 -o ens192 -j ACCEPT iptables -A FORWARD -i ens192 -o ens224 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERAD

    and this still didn't work. I'm trying to figure out what I am missing. any help is greatly appreciated.

    Server security: transfer and store data safely

    Posted: 29 Aug 2019 07:55 AM PDT

    Hello, big topic, but I'm looking for some introductory info on security-- specifically, securely transferring and storing data. Assume the data is (or can be) tabular in nature--customer contact records or similar--and needs to move from a web API, to a Linux2 server on AWS. Thank you in advance for any suggested reading, tutorial, tips, etc!

    Finding the path of a network hosted directory

    Posted: 29 Aug 2019 05:41 AM PDT

    I'm trying to figure out what command to run to find the path for directories that are hosted on a network. For example I know that I have home directories shared from a NAS. Obviously when I look at it it is just /home/myusername, but I want to know what that full path is, and if there is a command I can run that will return //NAS/PATH/TO/HOME/DIRECTORIES for example.

    just trying to get a working environment

    Posted: 29 Aug 2019 11:28 AM PDT

    i am very new to using linux but i am learning fast but i cant seem to understand why i cannot use the software store. i am not familiar w/ the terminology yet so sorry if i cant explain it correctly but feel free to ask questions. what i want to do is just start from scratch and have someone give me the input commands to install a new version of ubuntu so i can have a working software center. i should also add i am on a chromebook, have already done developer mode, and i have installed crouton and familiar w/ command line but thats about it. so if someone doesnt mind i'd like to walk through the install process with someone getting the input commands and then setting up an environement until i have a working software center so i can use libre office and kodi and whatever else i might like to add, thank u in advance!

    Questions about Rsync.

    Posted: 29 Aug 2019 07:42 AM PDT

    Hello! I am currently backing up my system using rsync and this command:

    rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} / BackupFolder

    A friend told me about this command and it seems to work but I had two questions.

    1) How am I able to put all the files back into the system to restore a backup? I can't seem to find the right flags for it and I don't want to mess it up. 2) Will I be able to go from a blank computer with only the base stuff of Linux to my current setup when restoring or do I have to backup some other things too?

    Thank you!

    Posted: 29 Aug 2019 09:29 AM PDT

    Required to use netbeans for c++, I got it up and working on Ubuntu but there's no real support happening. If I miss spelled a word it will underline it but by offer any assistants, it also doesn't seem to have inline support or auto completely (features that were in visual studio, though I realize it won't have as complete it has none )..

    Am I missing somthing? It's still completely usable just very bery plain

    Ubunutu Budgie, Window Tiling Manager help

    Posted: 29 Aug 2019 04:10 AM PDT

    Hello everyone!

    So I'm not super new to Linux, but I am quite new to wanting to get deeper in and choose more of the tools myself. I used to use popOS (and that came with a good "mission control" and some other stuff), however, I'm not a super huge fan of it in general and what it comes with. Therefore I'm now on Ubuntu Budgie (minimal instillation). I love this one and all the control I have, but there are some stuff I haven't been able to install or find alternatives for. Therefore I figured I'd ask for some help here and hope you guys can help me out.

    1. Does anyone know a good window task manager (eg. something like Apple's Mission Control). popOS came with one that was okay, but I didn't love it. Not sure if this is important, but I use virtual desktops. Preferably where I can have control over the shortcuts and such.
    2. Secondly I'm using an ultrawide, and I haven't found a good window tiling manager (something with grids and such). On Windows (since I sadly have to still use this for work), I use something called GridMove. I've added an image below how it works. Is there something similar for Linux? Eg. I move the app to the right or left and that shows me something like that divider. I did try gTile, but I felt it was a bit too much work. Eg. I had to press a shortcut on my keyboard, select a tile and drag from that tile, and not forget to have the app I want to tile selected. Since it didn't use edges or such, it happened quite a lot that I accidentally had the wrong app selected.

    ### GridMove

    GridMove

    I believe that is the current two things I'm struggling with. If I get more I'll probably do another post. :)

    Thanks in advance!

    Difficulties with dual booting with windows 10?

    Posted: 29 Aug 2019 12:43 AM PDT

    I am trying to dual-boot Linux and Windows.

    1) I wanted to do Mint, but I downloaded the .iso and both UUI and LiLi were unable to see it.

    2) I decided to try Ubuntu instead, but after running everything on UUI, disabling UEFI and disabling fast startup, I am unable to boot from the flash drive. I tried from the recovery/update menu, while holding shift and restart and hitting f2/f10 while restarting but I am unable to get to a ubuntu boot menu.

    Help, advice on either point is appreciated.

    Ubuntu 18.04 - Can't change icon of single application

    Posted: 29 Aug 2019 06:35 AM PDT

    In the past I've easily changed icons by going to usr/share/applications, going to properties of the program and changing the icon from there. This worked on my old laptop running Ubuntu 18.04. Now on my new laptop that I've just put the exact same 18.04 on, it doesn't work. Within usr/share/applications, right clicking on the program (Thunderbird) shows that the icon has changed within that menu, but the change isn't applied to the program icon as it appears in my Favourites bar/Show Applications. Thunderbird has been installed through the package manager & has an old, ugly icon that I want to replace with a newer one. Also should note that I'm successfully using a custom icon pack through Tweaks without error; every other application except this one is changed. I've even deleted all the other Thunderbird icons within the pack files & replaced it with my preferred icon & it still won't work.

    Stupid question about iOS and Linux

    Posted: 28 Aug 2019 09:58 PM PDT

    So I recently found my old iPod Touch running 4.2.1 and I was wanting to just make it into a clean slate. Effectively a mini computer (?). I'm not all that great with Linux, but I did manage to get Ubuntu installed on an ancient laptop I had kicking around. I'm just curious if this is even possible with such an old handheld device and if so, if anyone would be kind enough to give me some pointers?

    I may post over on /r/jailbreak as well; going to dig around more online too.

    Little help with mdadm RAID1?

    Posted: 29 Aug 2019 01:37 AM PDT

    I am following this tutorial (https://www.howtoforge.com/how-to-set-up-software-raid1-on-a-running-system-incl-grub2-configuration-debian-squeeze), I am on Ubuntu 18.04. Basically I am stuck after setting my root partition on fstab. When I reboot it mounts / as /dev/sda6 instead of /dev/md1. I think it is a grub issue but I can't figure out how to correctly make grub set up the correct partition as root. Any suggestion?
