! MIGRATION IN PROGRESS: config distro machine migration
|-
|Start to revamp config from [machine]/[distro] to [distro]/[machine] to match scripts.  It's not hard even though it's dangerous.  You can do each machine separately from others.  Get on it!
# DO THIS ALL IN ONE SESSION, do not log out
cd development/config
mkdir -p distro # prolly not needed
git mv machine/distro distro/machine
setup_stow.sh # repeat until it doesn't fail; check each failure to make sure it is a symlink, and simply rm them as you go

! Set up raspbian on a new Pi
|-
|-
| Here are all (most?) of the steps to get a raspbian OS going on the Pi (very similar to unbuntu-on-PC).
| Time Warner seems to keep giving the same IP back to my main linux router/server, as long as the NIC card doesn't change.  It also happened when they upgraded my service (and started labeling my IP as dynamic to SpamHaus, fuckers...).
* Get a Raspbian image from [https://www.raspberrypi.org/downloads/raspbian/ here]
* Create a boot MicroSD following [https://www.raspberrypi.org/documentation/installation/installing-images/linux.md this]
* Use gnome-disks to expand the root partition to 16GB, and create a nice ExFat share on the rest if there is more space
* Boot it up and fix the locale with
sudo locale-gen en_US en_US.UTF-8
  sudo dpkg-reconfigure locales # USE THE SPACE TO SELECT US and unselect GB (fucked up keyboard)
sudo dpkg-reconfigure keyboard-configuration # pick US or your keyboard is fubar
# now you have to reboot - this is a disaster pi, fix it
* Default user is pi/raspberry, better change that...
sudo adduser m
sudo passwd pi
sudo su - # and use [passwd] to set a known root password
* One-shot install of everything, then see more detailed notes, below...
sudo apt-get install kdm i3 i3lock i3status suckless-tools dunst openssh-server cifs-utils smbclient synergy arandr exfat-fuse exfat-utils hfsprogs gparted p7zip-full k4dirstat screen rxvt-unicode grdesktop openvpn bridge-utils kdiff3 nautilus-compare smartmontools automake libtool npm git network-manager-gnome iceweasel
* You may need to reconfig to use KDM so you can pick i3 (although if you log out that might work too - To logout, press Mod+shift+e (like exit) ):
sudo dpkg-reconfigure kdm
* One-shot dev install goes pretty well too:
sudo apt-get install scite sciteproj emacs build-essential automake libtool libssl-dev libbz2-dev python-dev curl libcurl4-openssl-dev php5-common php5-curl php5-cli php5-json php5-readline sqlite3 sqlitebrowser oracle-java8-jdk
* Install node with Node Version Manager (nvm) exactly the same way as in ubuntu (see above).
* Pull down and set up config, scripts like in Ubuntu.
* Pull down thedigitalage/rad-scripts, run [npm install]
* cd scripts/node/mah-hause, run [npm install], run [sy create] to create all dev repos.
There is no chromium-browser - use iceweasel (firefox on ARM) or epiphany-browser (which was enhanced specifically for pi).


My editors (Eclipse, sublime) are not really available, use scite instead.
If it changes, fix these things:
 
* Update the IP at 1and1.com for ALL domains, bleh...
Java [apt-get install oracle-java8-jdk] is available in the default raspbian apt repo.
* mod evasive has a whitelist, it needs the actual IP, bleh...

|-
|-
| The easiest way is to add a new drive just for OpenElec and install OpenElec to it with the installer.  But if you want to SHARE ONE DRIVE with other boots, DO NOT DO THAT :-) Do this instead:
| Resetting things sometimes has to be done in this precise order:
* On an existing refind-booted system, set up two new ext4 partitions
* cable modem -> blue cable -> **ONBOARD** bitpost NIC
** one about 2GB in size, labeled [SYSTEM], and marked as bootable
* LAN switch -> yellow cable -> **ADDON CARD** bitpost NIC
** the other with 10GB or more, labeled [STORAGE]
* power off bitpost and cable modem
** [http://wiki.openelec.tv/index.php/Manual_Installation prep the drives] (no journal, ssd trim)
* power up cable modem
* download openelec and mount; there are a couple ways:
* wait 5 minutes
** get the img and install to a thumb
* power up bitpost
** get the img and mount (see below)
* verify that you can ping google.com, LAN works, etc.
* Set up OE drives to mount in other OSes to /openelec-system and /openelec-storage
/dev/disk/by-label/SYSTEM  /openelec-system  ext4 noatime 0 0
/dev/disk/by-label/STORAGE /openelec-storage ext4 noatime 0 0
* copy target/KERNEL and target/SYSTEM to SYSTEM
cp OpenELEC_img/target/KERNEL /openelec-system/
cp OpenELEC_img/target/SYSTEM /openelec-system/
* set up UEFI boot
** subl /boot/efi/EFI/refind/refind.conf (and add this block)

''' Fixing boot '''
Windows Updates tend to clobber the EFI boot setup.
 
THen you have to set BIOS to boot with "UEFI+Legacy", and put the UEFI "USB" drive first in front of the "Windows Boot Manager" one.
 
THen reboot, you should get grub.
 
Go into Ubuntu and reinstall refind.
 
Boot back into bios, and set back to UEFI boot. Leave the USB drive first.  Reboot and yhou should get refind again.  FU Bill.
''' Install Ubuntu '''
To originally install ubuntu, I had to add [... --- nomodeset] to the boot line in the grub booter.
 
Then I had to use a desktop 1080p monitor - the 4k Sony would not come up for some reason.
 
The Seiki is working fine now, go figure.

General tasks
MIGRATION IN PROGRESS: config distro machine migration
Start to revamp config from [machine]/[distro] to [distro]/[machine] to match scripts. It's not hard even though it's dangerous. You can do each machine separately from others. Get on it! 
# DO THIS ALL IN ONE SESSION, do not log out
cd development/config
mkdir -p distro # prolly not needed
git mv machine/distro distro/machine
setup_stow.sh # repeat until it doesn't fail; check each failure to make sure it is a symlink, and simply rm them as you go

Maintenance of my music collection

Restarting everything

Add a new VM to melange - Clone a melange VM - Linux barebones quickstart

Scripts - Add a user - Linux permissions - DNS

Tune linux performance

Turn off ubuntu gnome screenlock - Set ubuntu default browser

Add a drive - Back up drive - Check disk - Check disk speed

Bash basics - OS X basics - DOS basics - Update gentoo kernel

SSL certificate instructions - Networking

systemd - udev: Assign unique names to your devices

Automatically mount and unmount your devices

udev: Autorun programs when connecting your devices

master keyboard shortcuts map
See .i3/config.

Typically you can press ctrl-shift-K to open it in editor.

The local file usually points to the common version, here: 

~/development/config/common/home/m/.i3/config
Upgrade Ubuntu
To update ubuntu from an i3 terminal: 
su -
apt-get update        # Fetches the list of available updates
apt-get upgrade       # Strictly upgrades the current package
apt-get dist-upgrade  # Installs updates (new major versions, i think)
update-manager -d    # kick off the update manager to migrate to new release when available

Or just call the script that does the same thing: 

upgrade_ubuntu

I'm currently migrating everything to 16.04 Xenial Xerus.

Test your drives - DO THIS OFTEN
Look at available tests: 
smartctl -c /dev/sdf # to peek at available tests and how long they typically take to run

Short test: 

smartctl -t short /dev/sdf
watch -n 3 smartctl -l selftest /dev/sdf # you won't see anything until it finishes, takes about 1 minute

Long test: 

smartctl -t long /dev/sdf
watch -n 3 smartctl -l selftest /dev/sdf # takes about 5 minutes
Increase max open file handles
I do it here: 
~/development/config/common/etc/sysctl.d/20_MDM_sysctl.conf

That basically sets the user max when I do my stow thing. Alternatively, you can set it directly in 

/etc/sysctl.conf
Mount an IMG file
You have to peek at the file with fdisk: 
fdisk -lu /home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img

From that you can tell the "units" and "Start" offsets: 

Device                                                                    Start    End Sectors  Size Type
/home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img1   2048 526336  524289  256M Microsoft basic data
/home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img2 528384 593920   65537   32M Linux filesystem

From there you can mount with a little math. Multiply the units by Start to get offset (512x2048=1048576), and use it to mount that partition: 

mount -t auto -o loop,offset=1048576 /home/m/bitpost/download/torrents/OpenELEC-Generic.x86_64-5.0.8-efi.img /media/m/iso

aifol

Chroot into gentoo from (say) ubuntu 
# These may already be done
mount /mnt/gentoo
cp -L /etc/resolv.conf /mnt/gentoo/etc/

mount -t proc none /mnt/gentoo/proc
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash

# ** NOW IN CHROOT **
env-update
source /etc/profile
export PS1="(chroot) $PS1"

# GET TO IT!  :-)
Windows symbolic links
Windows symlinks - needed for config files, svn overlay, etc.

I'm setting up hard links from sublime install folder to shared config settings: 

mklink [/H /D /J] link_path Target_file/folder_path

We had to use a soft link, hard won't go across drives. And you have to run the cmd window as admin. Don't specify type, and it will create a soft file link: 

mklink "C:\Users\Michael\AppData\Roaming\Sublime Text 3\Packages\User\Default (Windows).sublime-keymap" "D:\Michael's Data\development\config\common\home\m\.config\sublime-text-3\Packages\User\Default (Windows).sublime-keymap"
mklink "C:\Users\Michael\AppData\Roaming\Sublime Text 3\Packages\User\Preferences.sublime-settings" "D:\Michael's Data\development\config\common\home\m\.config\sublime-text-3\Packages\User\Preferences.sublime-settings"

Here is another example, setting up a link in an SVN repo folder to point to a git-controlled folder on another drive. SVN is OK with this, cool. 

(open ADMIN cmd prompt)
cd C:\CODE\QA\ContinuousIntegration\Trunk
mklink /J scripts "D:\Michael's Data\development\power_analytics\scripts"
  Junction created for scripts <<===>> D:\Michael's Data\development\power_analytics\scripts
Windows route traffic to avoid VPN
You can use "route" to assign paths to specific traffic.

So bitpost.com requests go through eth0 instead of VPN, eg... 

C:\WINDOWS\system32>route add 174.109.14.112 192.168.50.1

Note that you can do this with [route] in linux too, syntax is a bit diff.

Windows command prompt FULL SCREEN
Type cmd in start search box and right-click on the cmd shortcut which appears in the results. Select Run CMD as administrator.

Next, in the command prompt, type wmic and hit Enter. Now try to maximize it! Close it and again open it. It will open as a maximized window! You may have to ensure that the Quick Edit Mode in the Options tab is checked.

Hardware notes
NO TEARING on Sony driven by nvidia (currently, case)
It's not really about Kodi settings, you have to set up nvidia settings, and they are HARD to get to stick because it's "automatic" but broken.
  • Ensure nvidia-settings is set to 4k at 60fps refresh rate - YOU HAVE TO DO THIS ON EVERY REBOOT until we set up an xorg.conf FML
  • Ensure Kodi has "sync video to display" turned ON
Copy from linux nautilus to android "Operation unsupported"
Weird assed linux prevents "SMB to USB" copies, FUCKOFF. Workaround is to copy to local drive, then copy to phone. Wow that is sickening.
Old notes and dead boxes
Oontz turn on dual pairing
Turn them both on. One should be paired with your phone, the other should be flashing blue, trying to connect.

On the Play Control Speaker (speaker with solid Blue Light) press and hold down the Play/Pause button for 5 seconds until the flashing White Light appears and the speaker says “Dual Pairing”. - The Play Control Speaker will then connect to the second speaker.

There is NO WAY you can guess this. You'll be back here to re-learn...

Ubuntu and shitty Seiki
AMD

Radeon driver sucks, won't go over 1080p; and Dune (AMD chipset) overscans so you can't see the edge. The only fix I found was to use xrandr. It kinda sucks though bc it's a resize solution that blurs all pixels. Cest la vie. 

xrandr --output HDMI-0 --set underscan on
xrandr --output HDMI-0 --set "underscan hborder" 40 --set "underscan vborder" 22

Let's try the binary ATI driver. 

lspci -vvnn | grep VGA
[...] Advanced Micro Devices, Inc. [AMD/ATI] RS780 [Radeon HD 3200] [1002:9610]
nvidia

For 4k video on an nvdia chipset (like wimpy), first get Ubuntu to use nvidia's driver:

  • Go to System Settings-> Software & Updates
  • Select the Additional Drivers tab
  • Select the tested, proprietary NVIDIA binary driver
  • REBOOT - the nvidia driver works at the kernel level so you won't be able to just restart X. fools
  • WHY does ubuntu make you do all this?

Next, here is the "magic super-secret" Seiki 4K goo that should go in xorg.conf (if needed). It's from: http://ubuntuforums.org/showthread.php?t=2164924 See /etc/X11/xorg.conf for the full details:

Fix things after IP changes
Time Warner seems to keep giving the same IP back to my main linux router/server, as long as the NIC card doesn't change. It also happened when they upgraded my service (and started labeling my IP as dynamic to SpamHaus, fuckers...).

If it changes, fix these things:

  • Update the IP at 1and1.com for ALL domains, bleh...
  • mod evasive has a whitelist, it needs the actual IP, bleh...

  • reset cable modem (see specific steps)
Reset 1020 cable modem so it grants a real IP address (not private)
Resetting things sometimes has to be done in this precise order:
  • cable modem -> blue cable -> **ONBOARD** bitpost NIC
  • LAN switch -> yellow cable -> **ADDON CARD** bitpost NIC
  • power off bitpost and cable modem
  • power up cable modem
  • wait 5 minutes
  • power up bitpost
  • verify that you can ping google.com, LAN works, etc.

Before, at Peace Street... I had to stuff the goddamned drives right into the case since the rosewill was giving me such shit. In hindsight, it might not have been the rosewill at all... I am considering restuffing the box with the drives... but for now, i have this: 

sda  root
sdb1 tvmind
sdc1 film
sdd & sde softraid
sdf1 spicey
sdg1 reservoir
sdh1 plethora
sdi1 win

Before it was like this: 

   ================================
   BAYS of the bitpost.com Rosewill
   ================================

       To figure this stuff out, it was easiest to mount/umount drives and/or just access the mounted files
          (and watch the bay lights, of course)

        Disk layout:

            8 7 6 5
            4 3 2 1

        1) spicey-3g-mel
        2) reservoir-3g-mel
        3) tvmind-4g-mel
        4) newraid1-4tb-bp WD Black installed 2014-10-05

        5) plethora-3tb-bp i hope this was not being used - 3GB Seagate barracuda - mount says some ntfs looking thing with no partitions and unable to mount - so i reformatted ext4
        6) win-pax09 some old windows drive with lots of game goodies; also has sdf2 swap partition (kill it some day)
        7) film-6tb-bp WD Green installed 2014-10-05
        8) newraid2-4tb-bp WD Black installed 2014-10-05

   ================================

Before THAT, it was this... 8 bay SATA tower houses these drives:

  1. 2.0tb archive (sdb right?)
  2. 250gb landofthelost circa ABB timeframe /dev/disk/by-label/LandOfTheLost /dev/sdc1
  3. 1.5tb raid drive #1 /dev/disk/by-label/d-sp-raid -> ../../sdd1
  4. 2.0tb latest /dev/disk/by-label/d-sp-20newmovies -> ../../sde1
  5. 1.5tb raid drive #2 (needs label change maybe)
There are also these drive partitions:
  • / /dev/sda4
  • ubuntu root ub_root -> ../../sda5
  • /vista /dev/sda3
rtorrent keys
rtorrent CAN actually work pretty well, IF you pay attention to these basic keys:
  • enter - specify a torrent file to load - USE TAB COMPLETION
  • ctrl-d - STOP torrent, smack that shit, delete it forever
  • ctrl-s - START torrent - WARNING ONLY WORKS IF YOU DISABLE TERMINAL CAPTURE with...
stty stop undef
stty start undef
  • ctrl-o - change download dir
  • ctrl-k - close files - needed before ctrl-o, usually
  • ctrl-r - recheck hash

NOW GET rutorrent going!  :-)

rtorrent fix torrents that didn't move into place properly
* if the torrent is archived properly, use move_and_resymlink to move it: 
cd ~/download/torrents/archived/symlinks
move_and_resymlink [symlink] [destdir]
  • if things are a mess due to hard drive failure (etc), you should do this:
    • use r(u)torrent to see where rtorrent thinks the files are
    • copy the files, if available, to the final destination (under a .* dir in symlinks)
    • create a symlink: ln -s .music/Fresh/ELO-Secret\ Messages ELO-Secret\ Messages
    • close the torrent files (ctrl-k), move the destination (ctrl-o), start again (ctrl-s)
Creating a new ssh key pair for no-password access to a remote system
Say you've got a new machine with user [m] and you want to connect to it, do this:
  • install sshd, make sure it's running
  • get on the new machine - ssh to the new machine by typing the password if you don't have direct access
  • $ scp m@tdm:.ssh/id_rsa .ssh/
  • $ scp m@tdm:.ssh/authorized_keys .ssh/
wow I just had serious issues with basic ssh usage, so i'll put a summary on the wiki
   basically most misunderstandings stem from describing these two:
       client: machine that is trying to ssh into the server
       server: machine that the client user wants to get to
   most poor sots are just sitting on the client
   and they create a pair and push their public key to the server
   but in my case, more often, i want to create a pair on the server
   and push the private key to the multiple places i need to connect FROM
   when doing that, you have to push the public key into the server's authorized_keys
   and configure the client to juggle multiple private keys

       create a key pair:
           ssh suser@server
           ssh-keygen
               use defaults
               will create:
                   .ssh/id_rsa (private key)
                   .ssh/id_rsa.pub (public key)

       put the public key in place:
           cd .ssh
           cat id_rsa.pub >>authorized_keys

       put the private key on the client and configure:
           scp id_rsa cuser@client:.ssh/id_rsa_server
           ssh cuser@client
           em .ssh/config
               Host tdm thedigitalmachine.com
                 Hostname thedigitalmachine.com
                 IdentityFile ~/.ssh/id_rsa
                 User m
               Host server
                 Hostname server.com
                 IdentityFile ~/.ssh/id_rsa_server
                 User suser

bitpost LAN IP addresses
All IP address management happens on bitpost, via dnsmasq, which, rocks.
  • Set up machine names in /etc/hosts
  • Set up IP leases by MAC address in top of: /etc/dnsmasq.conf

Initially set up bitpost with DHCP as follows:

  • emacs /etc/conf.d/net
config_eth0="dhcp"
config_eth1="192.168.22.1/24"

Turn DHCP-assigned IP into static as follows:

  • /etc/init.d/net.eth0 restart
   dhcpcd[3867]: eth0: carrier acquired
   dhcpcd[3867]: DUID 00:01:00:01:1a:c3:6f:da:e0:3f:49:a3:4b:d9
   dhcpcd[3867]: eth0: IAID 49:a3:4b:d9
   dhcpcd[3867]: eth0: rebinding lease of 66.57.227.83
   dhcpcd[3867]: eth0: leased 66.57.227.83 for 86400 seconds
   dhcpcd[3867]: eth0: adding route to 66.57.226.0/23
   dhcpcd[3867]: eth0: adding default route via 66.57.226.1
  • emacs /etc/conf.d/net
config_eth0="66.57.227.83/23"
routes_eth0="default via 66.57.226.1"
  • /etc/init.d/net.eth0 restart

We will monitor and log success here to see how it goes.

  • 2014/05/05 set to static 66.57.227.83/23, gateway 66.57.226.1

Fixing boot Windows Updates tend to clobber the EFI boot setup.

THen you have to set BIOS to boot with "UEFI+Legacy", and put the UEFI "USB" drive first in front of the "Windows Boot Manager" one.

THen reboot, you should get grub.

Go into Ubuntu and reinstall refind.

Boot back into bios, and set back to UEFI boot. Leave the USB drive first. Reboot and yhou should get refind again. FU Bill. Install Ubuntu To originally install ubuntu, I had to add [... --- nomodeset] to the boot line in the grub booter.

Then I had to use a desktop 1080p monitor - the 4k Sony would not come up for some reason.

Follow the ubuntu install.

We also use a StarTech AC600 ac wifi adapter. The chipset is specified here. It's a Realtek - RTL8811AU. It is not supported with the vanilla 15.04 kernel, but it's easy to build a module from sources available on github: 

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/gnab/rtl8812au.git
cd ~/rtl8812au
make
sudo make install
sudo modprobe 8812au

Then, run NetworkManager and nm-applet, and as soon as you plug the USB dongle in and remove the wired connection, you'll get a running wifi applet, YES.

We also want to drive the crappy Seiki at 4K. A 4k mode shows up in our X probe, but ubuntu is not picking it...... yet...
