Enfim konsole lokal la lè w ap itilize x11vnc

Bonjou tout moun,

Gen anpil atik sou entènèt la sou sijè ki jan yo mete yon koneksyon aleka nan yon sesyon Xorg ki deja egziste atravè x11vnc, men mwen pa jwenn okenn kote ki jan yo siprime monitè lokal la ak opinyon pou nenpòt moun ki chita bò kote òdinatè a aleka fè pa wè sa w ap fè epi li pa peze bouton nan sesyon ou. Anba a koupe a se metòd mwen an pou fè x11vnc plis sanble ak konekte nan Windows atravè RDP.

Se konsa, an n di ou deja konnen ki jan yo sèvi ak x11vnc, si se pa sa, ou ka google oswa li pou egzanp. isit la.

Etandone: nou lanse x11nvc, konekte li ak kliyan an, tout bagay ap travay, men konsole lokal la nan òdinatè a disponib tou pou gade ak opinyon.

Nou vle: fèmen konsole lokal la (monitè + klavye + sourit) pou pa gen anyen ka wè oswa antre.

Fèmen monitè yo

Premye bagay ki te vin nan tèt ou se te tou senpleman fèmen monitè a atravè xrandr, pou egzanp tankou sa a:

$ xrandr --output CRT1 --off

men an menm tan an, anviwònman an fenèt (mwen gen KDE) kòmanse panse ke monitè a vrèman etenn epi li kòmanse voye jete fenèt ak panno, tout bagay deplase soti epi li vin tris.
Gen yon fason ki pi enteresan, ki se voye monitè a nan ibènasyon, ou ka fè sa pou egzanp tankou sa a:

$ xset dpms force off

men isit la tou, se pa tout bagay ki lis. Sistèm nan reveye monitè a nan premye evènman an. Beki ki pi senp la nan fòm yon sik ede:

while :
do
    xset dpms force off
    sleep .5
done

Mwen pa t 'panse plis - mwen te parese, li sèvi objektif li - monitè yo pa montre anyen, menm si mwen peze bouton yo, deplase sourit la, elatriye.

UPS:

Mèsi amarao pou yon lòt metòd ak vire klète a zewo:

$ xrandr --output CRT1 --brightness 0

Koupe opinyon an

Pou enfim opinyon mwen te itilize xinput. Lè yo te lanse san paramèt, li montre yon lis aparèy:

$ xinput
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Laser Mouse                  id=9    [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Power Button                              id=7    [slave  keyboard (3)]
    ↳ Sleep Button                              id=8    [slave  keyboard (3)]
    ↳ USB 2.0 Camera: HD 720P Webcam            id=10   [slave  keyboard (3)]
    ↳ HID 041e:30d3                             id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

Aparèy Nwayo Virtual... ou pa ka enfim li - yon erè parèt, men rès la ka vire sou ak koupe, pou egzanp, men ki jan ou ka rete san yon sourit pou yon minit:

xinput disable 9; sleep 60; xinput enable 9

Pare solisyon

Pou ka mwen an, mwen te fè yon script ke mwen kouri nan yon sesyon ssh. Li siprime opinyon lokal yo ak ogmante sèvè x11vnc la, epi lè script la fini, tout bagay retounen jan li te ye a. Kòm yon rezilta, nou te resevwa twa scripts, isit la yo (mizajou).

switch_local_console:

#!/bin/sh

case $1 in
    1|on)
    desired=1
    ;;
    0|off)
    desired=0
    ;;
    *)
    echo "USAGE: $0 0|1|on|off"
    exit 1
    ;;
esac

keyboards=`xinput | grep -v "XTEST" | grep "slave  keyboard" | sed -re 's/^.*sid=([0-9]+)s.*$/1/'`
mouses=`xinput | grep -v "XTEST" | grep "slave  pointer" | sed -re 's/^.*sid=([0-9]+)s.*$/1/'`
monitors=`xrandr | grep " connected" | sed -re 's/^(.+) connected.*$/1/'`

for device in $mouses
do
    xinput --set-prop $device "Device Enabled" $desired
done

for device in $keyboards
do
    xinput --set-prop $device "Device Enabled" $desired
done

for device in $monitors
do
    xrandr --output $device --brightness $desired
done

disable_local_console:

#!/bin/sh

trap "switch_local_console 1" EXIT

while :
do
    switch_local_console 0
    sleep 1
done

Aktyèlman, script prensipal la (mwen gen de monitè, mwen mete kanpe yon sèvè komen ak youn pou chak monitè).

vnc_server:

#!/bin/bash

[[ ":0" == "$DISPLAY" ]] && echo "Should be run under ssh session" && exit 1

export DISPLAY=:0

killall x11vnc

rm -r /tmp/x11vnc
mkdir -p /tmp/x11vnc/{5900,5901,5902}

params="-fixscreen V=5 -forever -usepw -noxkb -noxdamage -repeat -nevershared"

echo "Starting VNC servers"

x11vnc -rfbport 5900 $params 2>&1 | tinylog -k 2 -r /tmp/x11vnc/5900 &
x11vnc -rfbport 5901 $params -clip 1920x1080+0+0 2>&1 | tinylog -k 2 -r /tmp/x11vnc/5901 &
x11vnc -rfbport 5902 $params -clip 1920x1080+1920+0 2>&1 | tinylog -k 2 -r /tmp/x11vnc/5902 &

echo "Waiting VNC servers"
while [ `ps afx | grep -c "x11vnc -rfbport"` -ne "4" ]
do
    sleep .5
done

echo "Disabling local console"
disable_local_console

echo "Killing VNC servers"
killall x11vnc

Se tout. Konekte atravè ssh ak lanse vnc_server, pandan li vivan, nou gen aksè atravè vnc epi konsole lokal la etenn.

Mèsi pou atansyon ou, ajoute ak amelyorasyon yo akeyi.
