Update gentoo kernel
drives
|
My primary server 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:
- 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
90% ubuntu for development
10% gaming machine, has steam, low end half-height video card that works fine for Risk of Rain etc.
It has a mid-range video card, enough to drive 1080p x 2 for development.
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.

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.

BOX: Raspberry Pi 2 and 4k

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

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...

to install a new kernel that ubuntu will serve up...
build it in a chroot
back in ubuntu, copy it:
cp /mnt/gentoo/usr/src/linux/arch/x86_64/boot/bzImage /boot/linux-blahblbahba
and update grub. you can change em both or just the second (and rerun grub-mkconfig >/boot/grub/grub.cfg):
