Login to WordPress or other accounts using python selenium package

By Roland Ihasz / 20th January 2019 21st January 2019

The best way to install the selenium package is using the following command:

$ pip install selenium

or on macOS with Homebrew

$ brew install geckodriver

If you are using Anaconda just simply activate your virtual environment and then install geckodriver using the following command:

$ conda install -c conda-forge geckodriver

Then you’ll need a driver to interface with the browser you choose. I used Firefox in this example, therefore I downloaded the required geckodriver driver.
Drivers for other browser: selenium-python.readthedocs.io
You might need to set the PATH of your geckodriver.

This python source code will pull up a Firefox window and open the url that you need set https://yourwpdomain.com/wp-login.php, then find user_login and user_pass elements on the page (by the id) and finally send a click() function to the submitButton.
If everything goes well the next thing you should see is your WordPress dashboard page in the browser.

from selenium import webdriver

browser = webdriver.Firefox()
#browser = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')  
url = "https://yourwpdomain.com/wp-login.php" # set your WordPress domain
browser.get(url)  

username = browser.find_element_by_id("user_login") 
password = browser.find_element_by_id("user_pass") 

username.send_keys("yourUserName") # add your WordPress UserName
password.send_keys("yourPassword") # add your WordPress Password

submitButton = browser.find_element_by_id("wp-submit") 
submitButton.click()

from selenium import webdriver

browser = webdriver.Firefox()

#browser = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')

url = "https://yourwpdomain.com/wp-login.php" # set your WordPress domain

browser.get(url)

username = browser.find_element_by_id("user_login")

password = browser.find_element_by_id("user_pass")

username.send_keys("yourUserName") # add your WordPress UserName

password.send_keys("yourPassword") # add your WordPress Password

submitButton = browser.find_element_by_id("wp-submit")

submitButton.click()

If you are using Windows you might need to set the geckodriver PATH with FirefoxDriver.

browser = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')

1	browser = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')

How to use wget without adding –no-check-certificate

By Roland Ihasz / 20th January 2019 20th January 2019

You need to add a check_certificate = off line into your .wgetrc file in your Home directory.
Or simply run this command on your terminal.

echo "check_certificate = off" >> ~/.wgetrc

1	echo "check_certificate = off" >> ~/.wgetrc

After this wget will add this –no-check-certificate automatically from your .wgetrc file.

Install JDK 11.0.1 (LTS) on Ubuntu 18.04

By Roland Ihasz / 30th November 2018 30th November 2018

Update: End of Public Updates for Oracle JDK 8

Java SE 8 is going through the End of Public Updates process for legacy releases. Oracle will continue to provide free public updates and auto updates of Java SE 8, until at least the end of December 2020 for Personal Users, and January 2019 for Commercial Users. Source: oracle.com

Here is a step by step procedure how to install JDK 11.0.1 (LTS) on Ubuntu 18.04 x64

Download: jdk-11.0.1_linux-x64_bin.tar.gz

tar -xvf jdk-*.tar.gz
sudo mkdir -p /usr/lib/jvm/jdk-11.0.1/
sudo mv jdk-11.0.1*/* /usr/lib/jvm/jdk-11.0.1/

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk-11.0.1/bin/java" 1111
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk-11.0.1/bin/javac" 1111

tar -xvf jdk-*.tar.gz

sudo mkdir -p /usr/lib/jvm/jdk-11.0.1/

sudo mv jdk-11.0.1*/* /usr/lib/jvm/jdk-11.0.1/

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk-11.0.1/bin/java" 1111

sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk-11.0.1/bin/javac" 1111

update-alternatives: –install needs <link> <name> <path> <priority>

The priority is an important option when you have more than one Java version installed.

Use your favorite text editor.

$ sudo vim /etc/profile.d/javajdk.sh

export J2SDKDIR=/usr/lib/jvm/jdk-11.0.1
export PATH=$PATH:/usr/lib/jvm/jdk-11.0.1/bin
export JAVA_HOME=/usr/lib/jvm/jdk-11.0.1

$ source /etc/profile.d/javajdk.sh

$ sudo vim /etc/profile.d/javajdk.sh

export J2SDKDIR=/usr/lib/jvm/jdk-11.0.1

export PATH=$PATH:/usr/lib/jvm/jdk-11.0.1/bin

export JAVA_HOME=/usr/lib/jvm/jdk-11.0.1

$ source /etc/profile.d/javajdk.sh

You might need to reboot your system.

$ java --version
java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)

$ java --version

Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)

Use the following command to configure Java on your system:

sudo update-alternatives --config java

1	sudo update-alternatives --config java

There are 2 choices for the alternative java (providing /usr/bin/java).

BTCPayServer the self-hosted payment processor for Bitcoin and other cryptocurrencies.

By Roland Ihasz / 30th November 2018 9th December 2018

How it works

BTCPay Server is a self-hosted and automated invoicing system. When checking out, the customer is presented with an invoice. Each time, a different address is tied to a particular invoice, so there is no address re-use. BTCPay follows the status of the invoice through the blockchain and informs a merchant when he can fulfill the order safely.

BTCPay is a code, not a company. There is no third-party between a merchant and a customer. Merchant is always in full control of the funds. There are no processing or subscription fees. BTCPay Server is free to use and completely open-source, so developers or security auditors can always inspect the quality of the code.
