Little USB password paster

When using Spice and VNC to virtual machine consoles, and remote consoles like idrac and ilo, it is not alway possible to copy-paste.

When doing maintenance it is a annoyance to type a super strong and long password by hand, Prone to typing errors, timeouts. And following lockouts.

So i wanted to auto type the password.

First solution was to bind a little bash script to a key combination.

#!/bin/bash
# Usage: make a keypress shortcut to this script
# activate shortcut, and the script wil give you 10 seconds to click and focus remote console window.
# It pastes the password, and you can press enter to login
# ( you can use xdotool also to press enter for you )
sleep 10
xdotool type "SUP3Rl00000ngandcompl3xpasswo0d@#@#@#%$%$%%$-you-cant-type-me-without-erors"

I’ve bound this to a key combination on my workstation.

gsettings set org.gnome.settings-daemon.plugins.media-keys custom-keybindings "['/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/']"
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ name 'passpaste'
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ command '~/bin/passpaste.sh'
gsettings set org.gnome.settings-daemon.plugins.media-keys.custom-keybinding:/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/ binding '<Super>p'

This works, but only where this script is installed.
So not on colleagues machines, workstations with windows, and the super secret admin/root account sits in a file.

So i made a password key, which count be behind lock and key.

Using a digistump, a push-button and a resistor, the passpaster was born.

Program to flash on the digistump

#include "DigiKeyboard.h"
void setup() {
  DigiKeyboard.sendKeyStroke(0);
  DigiKeyboard.delay(1000);
}

void loop() {
  if (digitalRead(0) == HIGH) WorkPass();
  if (digitalRead(1) == HIGH) LtPass();
}

void WorkPass() {
  DigiKeyboard.print("SUP3Rl00000ngandcompl3xpasswo0d@#@#@#%$%$%%$-you-cant-type-me-without-erors");
  DigiKeyboard.println();
  DigiKeyboard.delay(50);
  setup();
}

void LtPass() {
  DigiKeyboard.print("secondlongpasswordifyouareusingtwobuttons");
  DigiKeyboard.println();
  DigiKeyboard.delay(50);
  setup();
}

Plug the Digispark into you machine, it wil emulate a HID device (Keyboard).
Get your remote console into focus, press button .. presto!

Missing one resistor

TODO:

  • 3D print a little case
  • pin protect?
  • rotary + display? (Like below)

It would be nice to have something like:

Rotary encoder 1 – selects which password to paste
Rotary encoder 2 – (1-255) does a encryption method on the password
Display shows : Password #32 – Crypt # 88
So you can have for example 255 passwords with 255 encryptions .. which to use when? Only you know.

Above can’t be done with a Digispark, so i’ll have to use a Arduino Pro Mini or a equivalent

Mount Taranaki New Zealand

While traveling New Zealand we went to see Mt Taranaki

Mount Taranaki (Māori: Taranaki Maunga), also known as Mount Egmont, is a dormant stratovolcano in the Taranaki region on the west coast of New Zealand’s North Island. It is the second highest point in the North Island, after Mount Ruapehu.

I made this timelapse using a Nikon D750.

Fixing a WD My passport not working in New Zealand

Leave a comment

I’ve got a backup disk for my photos.
You can connect it via USB and has a SDCard slot for your camera SDCards.
You can also connect to is using it as a Wifi Access Point.
(You can even install twonky!)

The cardreader should automatically copy a inserted card to its internal harddrive.
I’ve tested this at home, but here in New Zealand it woudn’t work.

So i started investigating.
(I was in the middle of nowhere, so I could not search for answers.)

I’ve got the juice ssh client on my phone.
Connecting to the AP will give you a IP, but whats the IP from de WD?
Just use JuiceSSH to make a local connection (to your android) first.
And type: ip neigh
This will give you the ip from neighbouring devices, thats only one .. the WD.

Connect to the WD with ssh using root@IPNUMMER (password should be same as you configured the device with)

Looking at the logs gave me some idea where the problem was.

It would not mount the sdcard! Why, that one is working.
(In de Nikon Camera and using a cardreader with OTG on my android)

I first wrote my own mounter and copy program. That worked, so i could at least backup my photos.
Now I could search for the problem.

My backup script named “script”

mkdir /tmp/fash ; mount /dev/mmcblk0p1 /tmp/fash mounts okay!

The sdmount.sh has a problem, it uses the timezone in its script.
This will work when in GMT+12 -> GMT-12.
But we are in NZ .. thats GMT+13

Removing some checks in above script (sdmount.sh)
(Adding timeoffset_min=8)
Made the script work for me again.
When I got home from our trip, I flashed a new firmware version on the device, which corrected the problem.

X-plane on linux

Starting x-plane can be a problem on Linux when screens are not properly detected. (Like order of screens or sizes)

Below is a three-screen start script for Linux.

#!/bin/bash
#Will start a three screen xplane session
#Screen are @ 1920x1080 resolution
numscreens=3
count=0
if [ -z $1 ] ; then
./X-Plane-x86_64 --monitor_bounds=0,0,1920,1080,1920,0,1920,1080,3840,0,1920,1080
 while [  $count -lt $numscreens ]; do
    sleep 1
    count=$( wmctrl -l | grep X-System | wc -l)
 done
fi
screencount=1
wmctrl -l | grep X-Syst |awk '{ print $1 }' | while read ; do 
	wmctrl -i -r "$REPLY" -T "X-System_$screencount"
	let  screencount=screencount+1
done
wmctrl -r "X-System_1" -e 1,0,0,1920,1080

Cured Salmon Gravlax

Most of the times i use my cold smoker to smoke the salmon, below is a experiment i have to revisit!

Gravlax (Swedish: [ˈgrɑ̂ːvlakːs]) or graved salmon is a Nordic dish consisting of salmon that is cured using a mix of salt and sugar, and either dill or sprucetwigs placed on top, and may occasionally be cold-smoked afterwards. Gravlax is usually served as an appetizer, sliced thinly and accompanied by hovmästarsås “mustard sauce”, in Denmark as rævesovs, literally “fox sauce”, and in Iceland as graflaxsósa), a dill and mustard sauce, either on bread or with boiled potatoes.

In olden times, the salmon was buried in the ground to ferment. I packed mine in foil and buried it in the garden for a few days.
