  • Mount NFS from Truenas

    mkdir -p /media/rick/pool1
    
    chown -R rick:rick  /media/rick/pool1
    

    Add the automount to: /etc/fstab

    truenas.thecave:/mnt/pool1   /media/rick/pool1   nfs    user,auto    0   0
    

    Retstart Nautilus to see the share in files:

    killall nautilus
    

    For other shares, just repeat the same process under directory ‘media’ with the name of the share substituted

FreeBSD Notes
  • rickR

    Remove old kernel images that are cluttering the system

    zstd-no-space-error.png

    Most of these errors are due to low or not enough space left in the root partition.

    If you are using a Debian flavor:

    sudo apt-get autoremove --purge

    zstd-error.png

    Inform grub whenever an old kernel is removed:

    update grub

    update-grub.png

    Remove the un-used kernel config files:

    These will be the files pre cursed as ‘rc’ where installed kernels use ‘ii’

    … As well as files no longer used or required due to dependencies

    This command will detect, print, and remove left over cruft from previously installed packages or scripts, that have been removed or updated.

    sudo dpkg --purge $(dpkg -l | awk '/^rc/{print $2}')

    purge.png

    You can re-run the following to view the installed kernel(s):

    dpkg --list | grep linux-image

    Install Ruby on Debian

    Install rbenv

    sudo apt install rbenv

    Then initialize the environment:

    rbenv init

    rbenv-init.png

    nano ~/.bashrc

    Type or paste the output above, Ctrl +x to save

    Apply:

    source .bashrc

    Install ruby-build

    Install git:

    sudo apt install git

    install-git.png

    mkdir -p "$(rbenv root)"/plugins

    Clone to local:

    git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

    clone-ruby.png

    curl -fsSL https://github.com/rbenv/rbenv-installer/raw/main/bin/rbenv-doctor | bash

    ruby-doctor.png

    Now install Ruby:

    print ruby versions available

    rbenv install --list

    rb-list.png

    Install the latest version unless you have a reason otherwise:

    rbenv install 3.3.0

    On this system there was an error compiling at this point with fiddle, as well as psych: ruby-failed.png

    Therefore manually installing the following filled dependencies

    sudo apt install libtool sudo apt install libffi-dev

    rb-compile.png

    rbenv global 3.3.0

    print installed ruby version

    ruby -v

    ruby-version-installed.png

    Re: Find or Locate a file or extension command line

    Install locate command linux: Use your sudo command!

    apt install mlocate

    OR:

    apt-get install mlocate

    OR:

    yum install mlocate

    Update the database:

    updatedb

    Depending on the size of the complete filesystem this could take a few minutes

    After the database has been populated:

    locate mariadb

    Where mariadb is the word your looking for
