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.
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:

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
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.
#!/bin/bash
echo -n "\""
for f in `cat "$1"` ;do echo "$f" | tr -cd "[A-HL]_[0-9]" ; echo ; done | grep -v '^$' |grep _ > /tmp/parsons
let count=0
for f in `cat /tmp/parsons| tr -cd "[A-HL] \n"` ;do
if [ "$f" = "LG" ] ; then g=0; fi
if [ "$f" = "LA" ] ; then g=1; fi
if [ "$f" = "B" ] ; then g=2; fi
if [ "$f" = "C" ] ; then g=3; fi
if [ "$f" = "D" ] ; then g=4; fi
if [ "$f" = "E" ] ; then g=5; fi
if [ "$f" = "F" ] ; then g=6; fi
if [ "$f" = "HG" ] ; then g=7; fi
if [ "$f" = "HA" ] ; then g=8; fi
if [ $count -eq 0 ] ;then
echo -n "*";
((count++))
last=$g
else
if [ "2$g" -eq "2$last" ] ; then echo -n "r" ; fi
if [ "2$g" -lt "2$last" ] ; then echo -n "d" ; fi
if [ "2$g" -gt "2$last" ] ; then echo -n "u" ; fi
last=$g
fi
done
echo "\""
Just place all files in a directory on a php enabled webserver. The bash script is being run daily. (parsons bash script is called from this main script) These will generate 2 files One with the filename and all useful text like composers. And a file with the filename and the parsons code. Example:

xrandr is an official configuration utility to the RandR (Resize and Rotate) X Window System extension. It can be used to set the size, orientation or reflection of the outputs for a screen.
Someone broke my screen at a hackers event. The terminal was really hard to read with the black parts, so i tilted the screen
Broken screen in 2013
Quiet friday at work, playing with my little trusty 2530p. I’m using xmonad, so i don’t need any fancy work laptop.
Fun with distorting the screen
Another quiet friday at work, working from home, i turned all monitoring displays upside-down, sideways, or rotated them every so much seconds.
While this is a lot of fun to use, i used this to get my monitorsetups exactly the way i wanted, at home or at work. Different screen sizes, height differences .. no problem.
A fun tool to use is: https://github.com/qurn/xrandr-keystone-helper
Trying to fix a computer from my computer collection.
Comx-35 (1983)
RCA 1802 CPU @ 2.8 Mhz
32K Memory
Apparenty something wrong with the graphics chip.
The COMX uses the RCA CDP1869 and CDP1870 Video Interface System (VIS), consisting of the CDP1869 address and sound generator and the CDP1870 colour video generator.
Maybe next to try : checking signals using a Logic Analyzer
Never ask me to reset your password, i you are to stupid to remember or not using a passwordsafe … I WILL give you a new password, and you WILL remember not having to ask me again. 🙂 On this day i drew some example pictures for colleages.
Okay .. now some tips to create uniq passwords for every site in you head.
NOTES! .. CNN example uses google as secret key .. Want to type faster and not using mouse? .. Press home!
Type website
