OpenVAS Proxy

In data centers, proxies are used to provide IP to virtual servers. After all, one server there can be used by a dozen users at the same time. And each needs to be allocated its own IP and port. All this is done through proxies.

If you're facing issues where Selenium WebDriver (using JUnit) is not able to locate elements that were detectable by Selenium IDE, there could be a few reasons for this discrepancy. Here are some common troubleshooting steps:

1. Timing Issues

Selenium WebDriver might execute commands faster than Selenium IDE, leading to timing issues. Add explicit waits in your WebDriver script to ensure that the elements are present or visible before interacting with them.

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

// ...

WebDriverWait wait = new WebDriverWait(driver, 10);

// Example: Wait for an element to be clickable
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id("yourElementId")));
element.click();

2. Different Browser Profiles

Selenium IDE may use a different browser profile or settings compared to your WebDriver script. Ensure that the browser profile and settings are consistent.

3. Synchronization Issues

Elements might not be fully loaded or rendered when WebDriver tries to locate them. Add proper synchronization mechanisms to wait for the page to be ready.

4. Browser Window Size

Ensure that the browser window size in Selenium WebDriver is suitable for the elements to be visible. Use the manage().window().maximize() method to maximize the browser window.

driver.manage().window().maximize();

5. JavaScript Execution

Selenium IDE may execute JavaScript differently than WebDriver. If your website relies heavily on JavaScript, ensure that WebDriver handles JavaScript appropriately.

6. Switching to Iframes

If the elements are inside iframes, make sure to switch to the correct iframe using driver.switchTo().frame() before interacting with the elements.

7. Browser Console Logs

Check the browser console logs for any error messages or warnings that might indicate issues with JavaScript or other resources.

System.out.println(driver.manage().logs().get("browser").getAll());

8. CSS Selectors and XPath

Selenium IDE may use different selectors than your WebDriver script. Double-check the selectors (CSS or XPath) used in your WebDriver script.

9. Browser Extensions

Selenium IDE may have browser extensions installed that affect the behavior of the web page. Ensure that WebDriver runs in an environment that mimics the configuration used by Selenium IDE.

10. Headless Mode

If Selenium IDE is running in headless mode, try running your WebDriver script in headless mode as well to replicate the environment.

If the issue persists after considering these points, you may want to inspect the HTML source of the page and compare it with the recorded script in Selenium IDE to identify any differences.

To see your proxy server and port, you'll need to check the settings of the application or software you're using that requires a proxy server. The steps to find the proxy server and port will vary depending on the application or software. Here are some general steps for common applications:

For Web Browsers:

1. Open your web browser (e.g., Chrome, Firefox, Edge).
2. Click on the menu button (usually three horizontal lines or three dots) and select "Settings" or "Options."
3. Look for a section related to "Network settings," "Proxy settings," or "Connections."
4. Find the proxy server address and port in the settings.

For Windows:

1. Press the Windows key + R to open the Run dialog.
2. Type "inetcpl" and press Enter to open the Internet Properties window.
3. Go to the "Connections" tab, and click on "LAN settings."
4. In the LAN settings, check the box next to "Use a proxy server for your LAN" if you have a proxy server configured. The proxy server address and port will be displayed.

For macOS:

1. Click the Apple menu and select "System Preferences."
2. Click "Network."
3. Select the network connection you want to check the proxy settings for (e.g., Wi-Fi, Ethernet).
4. Click the "Advanced" button.
5. Go to the "Proxies" tab.
6. Check the box next to "Use a proxy server" if you have a proxy server configured. The proxy server address and port will be displayed.

For Linux:

1. Open the Terminal.
2. Enter the following command to edit the network configuration file: sudo nano /etc/environment
3. Find the line that starts with "http_proxy" and check the value to find the proxy server address and port (e.g., "http_proxy=http://proxyserver:port").

If you are having trouble adding a SonarQube server authentication token to Jenkins, follow these steps to troubleshoot and resolve the issue:

1. Verify SonarQube server URL and credentials: Ensure that you have the correct SonarQube server URL and credentials (username and password) for the authentication token. Double-check for any typos or errors in the information.

2. Generate a new authentication token: If you have already used the current authentication token or it has expired, generate a new one from the SonarQube server. To do this, log in to the SonarQube server, navigate to "Administration" > "Security" > "General Settings," and click the "Generate" button next to the "Authentication token" field. Copy the new token.

3. Update Jenkins with the new authentication token: In the Jenkins "Manage Jenkins" section, click on "Configure System." Scroll down to the "SonarQube Servers" section and select the SonarQube server you want to configure. Enter the updated SonarQube server URL, username, and the new authentication token in the respective fields. Save the changes.

4. Verify Jenkins plugin version: Ensure that you are using the latest version of the SonarQube Scanner plugin for Jenkins. Outdated plugins might not be compatible with the latest SonarQube server version. To update the plugin, go to "Manage Jenkins" > "Manage Plugins," find the SonarQube Scanner plugin, and click "Update."

5. Check Jenkins job configuration: Verify that your Jenkins job is configured to use the SonarQube server you just updated. In the job configuration, under the "Build" section, ensure that the "Analyze source code with SonarQube" checkbox is selected and the correct SonarQube server is selected from the dropdown menu.

6. Test the connection: Run a test Jenkins job to see if the connection to the SonarQube server is successful. If the job fails, check the console output for any error messages related to the SonarQube server or authentication token.

If you continue to face issues, consult the Jenkins and SonarQube documentation, or reach out to their support communities for further assistance.

Rotary proxies are proxies that cyclically change their real IP address. This is used to make it harder to track their location. The port usually changes as well. How this happens depends on the software used on the proxy server.
