Enable hibernate / suspend to disk on Windows 10

Posted on by mario

I don’t know why, but the admins tend to disable hibernate via group policies from time to time. It is pretty simple to enable, but you need admin permissions.
This script first forces UAC and then enables hibernation.

@echo off

:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
    echo Requesting administrative privileges...
    goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
    echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
    echo UAC.ShellExecute "%~s0", "", "", "runas", 1 >> "%temp%\getadmin.vbs"

    "%temp%\getadmin.vbs"
    exit /B

:gotAdmin
    if exist "%temp%\getadmin.vbs" ( del "%temp%\getadmin.vbs" )
    pushd "%CD%"
    CD /D "%~dp0"

How to extract img src, title and alt from html using php

Posted on by mario

preg_match_all match the regexp in all the $html string and output everything as
an array in $result. “i” option is used to make it case insensitive

preg_match_all('/<img[^>]+>/i',$html, $result);

print_r($result);

Get the metadata

$img = array();
foreach( $result as $img_tag)
{
preg_match_all('/(alt|title|src)=("[^"]*")/i',$img_tag, $img[$img_tag]);
}

print_r($img);

Here you go.

iptables 101

Posted on by mario

How to do things with iptables. Safety first: How to reset everything.

sudo iptables -F
sudo iptables -X
sudo iptables -t nat -F
sudo iptables -t nat -X
sudo iptables -t mangle -F
sudo iptables -t mangle -X
Also, safety first: Don’t just copy something and run it on your server. You better understand what you are doing.
How to block a service?
Instead of using “DROP” you should use “REJECT –reject-with tcp-reset”. If you want to be able to access that service from the inside, you have to add an allow rule first.
sudo iptables -A INPUT -p tcp -s localhost --dport 3306 -j ACCEPT #mysql allow local
sudo iptables -A INPUT -p tcp --dport 3306 -j REJECT --reject-with tcp-reset #mysql

The “REJECT –reject-with tcp-reset” looks to the outside like there is no service running. A “DROP” will show that there is a firewall / iptables working.

Blocking an IP range

sudo iptables -A bannedDownloader -s 14.120.0.0/16 -j DROP

Disallow NTP queries

sudo iptables -A INPUT -p udp -s localhost --dport 123 -j ACCEPT #ntp allow local
sudo iptables -I INPUT -p udp --dport 123 -j REJECT #ntp

Block timestamp

sudo iptables -I INPUT 1 -p ICMP --icmp-type timestamp-request -j DROP
sudo iptables -I INPUT 1 -p ICMP --icmp-type timestamp-reply -j DROP
sudo iptables -A INPUT -p icmp --icmp-type 13 -j DROP

PHP XML tag contains colon

Posted on by mario

With PHPs’ simple xml functions it is possible to read xml easily. However, that doesn’t work any longer when a tag contains a colon. That tag is simply ignored and can’t be accessed. Often in RSS feeds there is content:encoded.

There is a trick. Instead of using simplexml_load_file use

$feed = file_get_contents($url);
$feed = str_replace("<content:encoded>", "<contentEncoded>", $feed);
$feed = str_replace("</content:encoded>", "</contentEncoded>", $feed);
$xml = simplexml_load_string($feed);

have fun!

Thai Fried Rice

Posted on by mario

ingredients

  • 1.5 cups of cooked Jasmine rice cooled (or day old rice works well too)
  • 250g minced beef
  • some green onions
  • ¼ of a big white onion
  • 2 cloves garlic
  • 1 egg
  • ½ tablespoon soy sauce
  • ½ tablespoon oyster sauce
  • Pinch of sugar (optional)
  • 1 tablespoon of oil for frying
  • 5 chilies
  • 3 tablespoons of fish sauce
  • ½ of a lime

instructions

Peel 2 cloves of garlic, and then just finely mince them. Slice ¼ of a sweet white onion into medium sized strips. Finely dice about 3 – 4 green onions.
Turn on your stove to medium high, heat up your wok (or frying pan), and add about 1 tablespoon of oil.
Once your oil is hot, add the garlic first, and stir fry continuously for about 15 seconds or so, until it gets nice and fragrant Next, toss in your minced beef, and fry for about 30 seconds. Add in a little less than ½ of your rice first. This is going to soak up all those
delicious minced beef juices and oils and keep your rice nice and dry. Stir fry for about 10 more seconds – This is a little known trick to make good rice, so it remains nice and dry. Scoot all your rice to one side of the pan, and then crack in the egg into the empty side.
Whirl the egg up, let it cook for a few seconds, and then start to mix it up with the rice and minced beef
Keep stir frying for about 20 seconds until the egg is fully cooked, and then add in the rest of your rice, and give it a quick stir.
Add ½ tablespoon of soy sauce, ½ tablespoon of oyster sauce, just a pinch of sugar (optional), and continue stir frying your rice, making sure all the sauce get mixed in.
Then add your chopped onions, and stir fry for another 30 seconds until the vegetables wilt, but they can still be crisp and not fully cooked
Lastly, toss in your green onions, stir it a few more seconds, and it’s ready to plate.
Slice off a wedge of lime, and serve it on the plate next to the rice. For the final touch, I like to sprinkle some freshly ground black pepper and Chili flakes. Add 3 tablespoons of fish sauce to a small bowl. Slice about 5 Thai chilies (you can add more or less, up to you), and add them to the fish sauce. Finally, I like it with a little squeeze of about ½ of a lime – but this is optional – and at many Thai restaurants it’s only fish sauce and chilies. That’s it, give it a stir, and put on top of your fried rice for extra saltiness
