====== Bullseye (11) Basics ======

===== Apt =====

==== Desktop machine ====

This has x as a dependency:

  #  ruby-qt4 no longer a package in buster

  apt-get install git curl screen build-essential pkg-config ruby ruby-dev rubygems \
  libmagickwand-dev jhead exiftool linux-headers-$(uname -r) make zsh \
  perl libwww-perl libxml-perl libxml-simple-perl atomicparsley rtorrent \
  dolphin vlc python-pip net-tools
  
  gem install rmagick mini_exiftool pry awesome_print
  
  pip install cheat

==== Headless ====

Somewhat bloated, with system ruby:

  apt-get install git curl screen build-essential pkg-config ruby ruby-dev rubygems \
  linux-headers-$(uname -r) make zsh perl libwww-perl libxml-perl libxml-simple-perl atomicparsley rtorrent \
  python-pip net-tools
  
  gem install rmagick pry awesome_print
  
  pip install cheat

Starter set, for use with rbenv:

  apt-get install git curl screen build-essential pkg-config linux-headers-$(uname -r) make \
  zsh perl libwww-perl libxml-perl net-tools

==== Web-accessible ====

[[https://www.digitalocean.com/community/tutorials/initial-server-setup-with-debian-10|DO recommend]] installing ''ufw''.  As root:

  apt install ufw
  ufw app list
  ufw allow OpenSSH
  ufw enable
  ufw status

And to add Apache access (80 + 443):

  ufw allow WWW Full

  
  
==== Windows 10 ====

Also headless:

  sudo passwd
  
  apt-get install git curl screen build-essential pkg-config ruby ruby-dev \
  make zsh perl libwww-perl libxml-perl libxml-simple-perl atomicparsley rtorrent \
  python-pip net-tools
  
  gem install rmagick pry awesome_print
  
  pip install cheat
  
  mkdir ~/.screen && chmod 700 ~/.screen

===== Networking without X =====

<del>''eth0'' just became something like ''enp2s0''.  However, if you ask for a predictable network name in ''raspi-config'', you end up with something like ''enxb827ebb6be60''.</del>  Seems to have gone back to ''eth0''.


''/etc/network/interfaces'' seems to be deprecated on Raspbian so that dhcpcd has overall control.

Edic ''/etc/dhcpcd.conf'', which is well commented and self-explanatory (start by uncommenting ''interface eth0'').  Reboot to update dhcpcd.

<del>If you're configuring it manually then something like this in ''/etc/network/interfaces'' will set the default gateway (network, broadcast and gateway are optional):</del>

<code>
auto enp2s0
iface enp2s0 inet static
  address 10.0.0.1
  netmask 255.255.255.0
  gateway 10.0.0.2
</code>

If you want to add an IPv6 address, too, append something like:

<code>
iface enp2s0 inet6 static
  address 2001:db8::c0ca:1eaf
  netmask 64
  gateway 2001:db8::1ead:ed:beef
</code>

===== Config =====

Clone ''bin'' and ''config''.

  for w in .bashrc .profile .bash_profile .zshrc; do
    mv "$w" "$w".default
  done

  # .promptrc no longer shell-independent

  for x in .porridge .aliases .bash_profile .bashrc .cheat .dircolors .get_iplayer .gitconfig .gitignore .hints .ispell_british .lftprc .profile .rspec .rtorrent .rtorrent.rc   .screenrc .shellrc .zshrc .pry .pryrc; do
    ln -s config/"$x" "$x"
  done
  
  for y in .screenrc.local; do
    cp config/"$y" "$y"
  done

===== Keymap =====

Keymap configuration (as root):

  export CONFIG=/home/slack/config
  
  cd /usr/share/X11/xkb/symbols
  mv gb gb.default
  ln -s "$CONFIG/gb" .
  
  cd ../rules
  for f in evdev.xml base.xml
  do
    mv "$f" "$f.default"
    ln -s "$CONFIG/$f" .
  done

===== Host =====


  cd /etc
  mv hosts hosts.default
  cp "$CONFIG/root/hosts" .

<del>ln -s "$CONFIG/root/hosts" .</del> <--- doesn't work

===== Oh my zsh =====

  sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
  cd .oh-my-zsh/custom
  mkdir themes
  cd themes
  ln -s ../../../config/zsh-custom/slack.zsh-theme
  cd
  rm .zshrc
  mv .zshrc.pre-oh-my-zsh .zshrc
  git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

===== Mount ntfs =====

  UUID=blah  /huge ntfs  uid=1000,gid=1000,umask=022,auto  0  0

===== Regional settings =====

For ''gnome-terminal'' to load, ''/etc/environment'':

    LANG="en_GB.UTF-8"
    LCALL="en_GB.UTF-8"
    
Which won't help, of course.
