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:
- 2.0tb archive (sdb right?)
- 250gb landofthelost circa ABB timeframe /dev/disk/by-label/LandOfTheLost /dev/sdc1
- 1.5tb raid drive #1 /dev/disk/by-label/d-sp-raid -> ../../sdd1
- 2.0tb latest /dev/disk/by-label/d-sp-20newmovies -> ../../sde1
- 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
all is full of light

| 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:
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
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

| My primary dev box
This used to be the primary Kodi box up until 10/2015, should still be current.
It has the same high-end i5 or i7 of other 2015 boxes, fast.
It has a mid-range video card, enough to drive 1080p x 2 for development.

- /dev/sda contains ubuntu, kodi, windows - using ubuntu 90% of the time

| BOX: case

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

You can override settings in /flash/config.txt; here's how, from here:
mount -o remount,rw /flash
nano /flash/config.txt
# Make your changes, then ctrl+x to save.
mount -o remount,ro /flash
reboot
Settings for 4k (from here)...
disable_overscan=1
hdmi_ignore_edid=0xa5000080
hdmi_cvt 3840 2160 30
framebuffer_width=3840
framebuffer_height=2160
hdmi_group=2
hdmi_mode=87
hdmi_pixel_freq_limit=400000000
max_framebuffer_width=3840
max_framebuffer_height=2160
I couldn't get 4K to stick in OpenELEC tho (except for the splash screen(!))...
Settings->System->System->Video->Refresh->30Hz
Settings->System->System->Video->Resolution->3840x2160
(it won't come up, just drops back to 1080p.. just as well, video at 30fps sucks...)
And to overclock the Pi 2 (from here):
# OVERCLOCKING TO 1.1 GHz, EXTREME
# default is 700
# this will NOT void the warranty :-)
arm_freq=1000
sdram_freq=500
core_freq=500
over_voltage=6
temp_limit=80 #Will throttle to default clock speed if hit.
#
# there is also the "turbo" thingee (that "voids warranty", hot!!)
#force_turbo=1

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...

Macbook Pro quad boot (OS X Yosemite, Windows 10, Ubuntu 15.04, gentoo)
see blog entry for quad boot instructions
- Installing Windows 10
- Upgraded existing Windows 8.1
- Hack the INF file of the nvidia driver to get it to install - runs PERFECTLY
- Add bluetooth stack - or not - i think i ended up back at the default Windows
- keyboard driver to get function key working: /spiceflow/softraid/software/OS/windows/macbook_windows10_drivers/AppleKeyboardInstaller64.exe
-- gentoo --
- see this for kernel parameters
- emerge microcode-ctl (and made it a module in kernel)
- also did everything else I could on this page (some EFI stuff was missing, who cares) - did i do too much?
- add m to a bunch of groups:
- for x in wheel cdrom cdrw usb video ; do gpasswd -a m $x ; done
- using Xfce (everybody's doing it)
- echo "exec startxfce4" > ~/.xinitrc
- using nvidia driver
- eselect opengl set nvidia
- run nvidia-xconfig
- using gdm
- emacs /etc/conf.d/xdm
- rc-update add xdm default
- using NetworkManager
- + consolekit (needed for applet)
- + nm-applet (for Xfce taskbar applet, where it all happens)
- + networkmanager-openconnect
- network driver: broadcom-sta
- Checking for suitable kernel configuration options...
- CONFIG_MAC80211: should not be set. But it is.
- Please check to make sure these options are set correctly.
-- to update kernel --
- under gentoo, ubunbu should already be mounted; make sure it's available at /ubuntu
- cd /usr/src/linux
- build a new kernel as usual
- make menuconfig, or make oldconfig, or whatever
- make && make modules_install
- emerge nvidia-drivers
- cp arch/x86_64/boot/bzImage /ubuntu/boot/linux-3.10.7-gentoo_oldconfig
- carefully fix up grub, ubuntu grub is being used
- we inject our gentoo boot lines into /boot/grub/grub.cfg through /etc/grub.d/11-gentoo-proxy
- which gets its information from /etc/grub.d/proxifiedScripts/gentoo
- we can modify grub directly from gentoo - you have to change both grub.cfg AND /etc/grub.d/proxifiedScripts/gentoo to keep things from getting clobbered later
- or go into ubuntu and change /etc/grub.d/proxifiedScripts/gentoo and run this...
- grub-mkconfig >/boot/grub/grub.cfg
- reboot!
-- misc --
- heres what we need in fstab to mount ubuntu in gentoo with [mount /ubuntu]...
- mount /dev/disk/by-path/pci-0000\:00\:0b.0-scsi-0\:0\:0\:0-part5 /ubuntu
| old wallee gentoo networking notes - using ubuntu now!

| Laptop has both wired and wifi adapters.
We set up custom network interface names to make it more clear.
I had installed several tools when attempting to get this going. DO NOT DO THAT, they interfere with one another. Removing NetworkManager and going with the highly-recommended wpa_supplicant and its graphical tools wpa_gui and wpa_cli.
I'm documenting this since it's so basic yet such a bitch.
/etc/udev/rules.d/76-mdm-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# MDM following this to change nw interface names:
# http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=2
#
# verified MAC addresses
# changed eth0 line to lan0
# changed eth1 line to wifi0
# PCI device 0x10de:0x0ab0 (forcedeth)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:26:4a:18:ed:58", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="lan0"
# PCI device 0x14e4:0x432b (wl)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:26:bb:07:d3:7d", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="wifi0"
Next you have to set up these weird symlinks:
cd /etc/init.d
ln -s net.lo net.lan0
ln -s net.lo net.wifi0
Now add them to runlevels:
rc-update add net.lan0 default
rc-update add net.wifi0 default
Now add them to runlevels:
rc-update add net.lan0 default
rc-update add net.wifi0 default
Fix the system so that only one is required for startup to work...

No, we're not even close to done yet...

Nope. What a fuckbucket of retardedness.
Look at the notes this guy made - brief but heavy - i think i need to purge b43 and get the "wl" driver working instead.

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.
