Lenovo ThinkPad 420 finomhangolás linuxon. I. (TouchPad)

Az alábbi beállításokat a netről vadásztam. (Ubuntu alapú rendszeren tesztelve)

1. Gépelés közben hogyan kapcsoljuk ki a touchpad-et?
A /usr/share/X11/xorg.conf.d könyvtárban található 70-synaptics.conf fileról csináljunk másolatot az /etc/X11/xorg.conf.d könyvtárba,
Majd az optionnal kezdődő részeket másoljuk bele:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "PalmDetect" "1" 
        Option "PalmMinWidth" "8"
        Option "PalmMinZ" "100"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
# http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
      MatchDevicePath "/dev/input/event*"
EndSection

Újra kell indítani az X-et.
2. Synaptic kikapcsolása egér csatlakoztatásakor:
Hozzunk létre, egy /etc/udev/rules.d/01-touchpad.rules fájlt a következő tartalommal:

SUBSYSTEM=="input", KERNEL=="mouse[0-9]*", ACTION=="add", ENV{DISPLAY}=":0", ENV{XAUTHORITY}="/home/username/.Xauthority", RUN+="/usr/bin/synclient TouchpadOff=1"
SUBSYSTEM=="input", KERNEL=="mouse[0-9]*", ACTION=="remove", ENV{DISPLAY}=":0", ENV{XAUTHORITY}="/home/username/.Xauthority", RUN+="/usr/bin/synclient TouchpadOff=0"

/etc/init.d/udev restart szükséges.

Arduino NTP Clock + Nokia 5110 LCD

Hálozatba kötött óra, ethernet interface dhcpvel, az időt ntpvel szinkronizálja.

Alkatrészlista:
Arduino Mega/Uno
Nokia 5110 Kijelző
Ethernet shield
Breadboard

NTP Clock

A sketch több létező projektből lett összeállítva kissebb módósításokkal, a forrásokat megjelöltem.

Nginx+php-fpm vhost creator

Ez a csomag megkönnyíti nginx vhostok keszítését php-fpm használatával. Minden vhos külön felhasználói joggal fog futni, így megnöveli a szever biztonságát.

A csomag 2 db template file-t tartalmaz, valamint a scriptet.

cp /usr/local/vhost/$USER.conf /etc/php5/fpm/pool.d/
ln -s /etc/nginx/sites-available/$DOMAIN.conf /etc/nginx/sites-enabled

A fenti templateket az /usr/local/vhost konyvtárba kell másolni, a bash sctiptet célszerű az /usr/local/bin könyvtárba.

Ha a vhostcreate scriptet paraméter nelkül indítjuk, akkor kiírja a paraméterezési lehetősegeit.
Mivel tcp portra bindel a php-fpm (megoldhato sockettel is),így minden vhostnál növeljük egyel a tcp port számát.

Tesztelve Ubuntun.

MySQL UTF-8

Gyakran okoz problémát, hogy adatbázisunk latin1 vagy más egzotikus kódlappal lett létrehozva.
Ezzel a scripttel az adatbázis, annak táblái, valamint a mezők kódlapját tudjuk egyszerűen átállítani:

<?php
if ($argc != 4)
{
  echo $argv[0]." <USERNAME> <PASSWORD> <DATABASE>\n";
  echo "change database table and fields collation to utf8_hungarian_ci\n";
    exit(1);
}

// Configuration Section
$server = 'localhost'; //probably localhost but change if required
$username = trim($argv[1]); // get username from commandline
$password = trim($argv[2]); // get password from commandline
$database = trim($argv[3]); // get databas name from commandline
$new_charset = 'utf8'; // change to the required character set 
$new_collation = 'utf8_hungarian_ci'; // change to the required collatio
// Connect to database
$db = mysql_connect($server, $username, $password); if(!$db) die("Cannot connect to database server -".mysql_error());
$select_db = mysql_select_db($database); if (!$select_db) die("could not select $database: ".mysql_error());

// change database collation
mysql_query("ALTER DATABASE $database DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci");

// Loop through all tables changing collation
$result=mysql_query('show tables');
while($tables = mysql_fetch_array($result)) {
$table = $tables[0];
mysql_query("ALTER TABLE $table DEFAULT CHARACTER SET $new_charset COLLATE $new_collation");

// loop through each column changing collation
$columns = mysql_query("SHOW FULL COLUMNS FROM $table where collation is not null");
while($cols = mysql_fetch_array($columns)) {
$column = $cols[0];
$type = $cols[1];
mysql_query("ALTER TABLE $table MODIFY $column $type CHARACTER SET $new_charset COLLATE $new_collation");
}

print "changed collation of $table to $new_collation\n";
}
print "\n";
print "The collation of your database has been successfully changed!\n";
?>

Windows 7 telepítő készítése

Kellékek:

Windows Automated Installation Kit: http://www.microsoft.com/downloads/hu-hu/details.aspx?familyid=C7D4BC6D-15F3-4284-9123-679830D629F2&displaylang=hu

Egy program mellyel iso fájlokbol másolhatunk ki tartalmat: pl MagicIso: http://www.magiciso.com vagy DaemonTools: http://daemontools.hu/

Windows 7 32 és 64 bites .iso

Opcionálisan:

Windows 7 Enterprise 32 és 64 bites .iso

Első lépések:

Hozzuk létre az általunk preferált meghajtó gyökerében  a következő 2 könyvtárat  \images és \master.

A Windows 7 32 bites iso tartalmát másoljuk a \master könyvtárba.

Lépjünk be a \master\sources könyvtárba, és töröljük a ei.cfg valamint az öszzes install*.clg fájlt.

Helyezzük átt az install.wim fájlt az \images könyvtárba és nevezzük át x32.wim-re.

Másoljuk ki a Windows 7 64 bites iso-ból a \sources\install.wim-et a \images\ -be és nevezzük át x64.wim-re

Másoljuk ki a Windows 7 32 bites  Enterprise iso-ból a \sources\install.wim-et a \images\ -be és nevezzük át e32.wim-re

Másoljuk ki a Windows 7 64 bites  Enterprise iso-ból a \sources\install.wim-et a \images\ -be és nevezzük át e64.wim-re

Vizsgáljuk meg a wim fileok tartalmát a következőképpen: imagex/info <valami>.wim

A kimenet xml formátumu:

Keressük meg a <IMAGE INDEX=”szám”> és <NAME>valami</NAME> címkéket

Az x32.wim esetében a következőket kell tartalmaznia

index 1 Windows 7 Starter
index 2 Windows 7 HOMEBASIC
index 3 Windows 7 HOMEPREMIUM
index 4 Windows 7 PROFESSIONAL
index 5 Windows 7 ULTIMATE

x64.wim esetében nincs starter, a kimenet így alakul:

index 1 Windows 7 HOMEBASIC
index 2 Windows 7 HOMEPREMIUM
index 3 Windows 7 PROFESSIONAL
index 4 Windows 7 ULTIMATE

e32.wim és e64 wim esetében:

index 1 Windows 7 Enterprise

https://www.raymond.cc/blog/create-x86-x64-all-one-windows-7-iso/

A batch file által létrehozott install.wim file-t másoljuk a \master\sources könyvtárba.

A következő parancs megadásával létrehozzuk a végleges iso imaget:

oscdimg.exe -lMulti-Windows-7 -m -u2 -b”D:\Master\Boot\etfsboot.com” D:\Master D:\Multi-Windows-7.ISO

FIGYELEM: SP1 iso esetében az Enterprise nem fér fel a dvd imagere. Célszerű külön dvdt generálni, illetve 32 és 64 bites dvdket generálni.

Néhány kép a kész telepítőkről:

32 és 64 bites windows telepítők (Enterprise nélkül)

Partíció írhatóságának tesztelése

Előfordul némely esetben hogy a felmountolt backup partíció csak olvashatóként csatolódik,  ezzel az egyszerű szkriptel tesztelhetjük:


#!/bin/sh
PROGPATH=`echo  | sed -e 's,[\\/][^\\/][^\\/]*$,,'`
. $PROGPATH/utils.sh
TMP=`mktemp`
if [ -f $TMP ] ; then
    echo OK;
    rm $TMP;
    exit $STATE_OK;
else
    echo ERROR;
    exit $STATE_ERROR
fi;


Cisco EPC3925 EuroDOCSIS 3.0 2-PORT Voice Gateway

A fenti terméket a szolgáltatótol kaptam.

Több hónap használat után problémák adódtak, ezért cserét javasoltak.

Lementettem a backup funkcióval a config-ot.

Betettük az új eszközt: User/Pass: semmi/semmi

Visszatöltöttem a mentést, majd azonnal nem engedett be.

Restore esetén az usernevet nem állítja vissza, csak a jelszót, tehat semmi/jelszó a megoldás valamint a vpn beállítások sem kerültek visszaállításra, újra be kell állítanom.
