We Asked 10 Linux Questions to ChatGPT and We Got Amazing Answers

What is ChatGPT

If you are very busy and still did not hear about this internet buzz or you see it but did not actually know what it then we are here to tell you.ChatGPT is a language model developed by OpenAI, it is one of the many AI chatbots of its kind, there are other AI models such as GPT-2 (a predecessor of ChatGPT) developed by OpenAI and other companies like Google, Microsoft, Amazon, and IBM have also developed similar models. Whenever you chat or mail to google or Microsoft every time the chatbot replies to your general queries, only in case of escalation humans are involved.

The inspiration behind the creation of ChatGPT and other AI models like it is to create a machine that can understand and generate human-like text. These models are based on a neural network architecture called the transformer, which has shown to be very effective at natural language processing tasks such as language translation, text summarization, and question answering.

The idea behind creating such models is to make the computer understand human language more efficiently so that it can be used in various industries like customer service, content creation, and more. These models are also being used to improve the accuracy and efficiency of machine learning models in a wide range of applications such as speech recognition, natural language understanding, and others.

Additionally, OpenAI’s goal is to advance AI in a way that is safe for humanity and to provide the most powerful AI technologies to those who will use them to benefit humanity. OpenAI aims to make this available to everyone so that the benefits of AI can be widely distributed.

Who Owns OpenAI?

Elon Musk, Sam Altman,Wojciech Zaremba, Ilya Sutskever,and , Greg Brockman founded OPENAI in 2015 . ELON musk stepped out in 2018 and the current CEO is Sam Altman. The most important event is that Microsoft invested 1 Billion dollars in OpenAI, Maybe in the future, you can see OpenAI features in your Windows Office applications

You may be Interested : Most Important 22 Linux Commands

We have asked 10 Linux questions to ChatGPT, and let’s see how amazing it’s answered it. Did ChatGPT able to clear the Linux System Admin interview?

Create a User and the password expire in 60 days.

ChatGPT has done good work and is able to give the correct answer to this basic question. So one point to ChatGPT.

How to delete User with home directory?

ChatGPT again did good work it will help you delete the home directory of a user with the user account in Linux. For this question, you don’t need to go to StackOverflow. One point to this AI chatbot.

How to Troubleshoot SSH issues?

Ohh here we are quite disappointed with ChatGPT’s answer because we all know “systemctl status ssh” will give us an error that ssh. service not found. The correct command is “systemctl status sshd“. We are disappointed because if a person with a beginner level works on this then he could try the second step to install the ssh server and in case ssh is installed he will be quite confused that why it not showing service available . The steps provided by ChatGPT AI is quite basic and maybe if we ask the second time we get other options but we have tried once and in one go we got basic steps.

So in this case 0 points to ChatGPT.

How to formate a 4TB harddisk ?

This is a trick question we have asked here ChatGPT failed to give the right answer. If you get what is wrong in this then congrats you are working on a good data center or Big project. If you are thinking about what is wrong with this then let me tell you above 2TB drive we have to use parted command otherwise you will get the error.

So 0 points to ChatGPT on this trick question.

Related : How to use parted command ?

how to create 500 GB LVM from 1 TB raw device in RedHat Linux?

Awesome now as expected we have got out the correct answer from this popular AI chatbot. You can just copy and paste commands to create LVM in Linux just you need to change names as per your device and requirements.

Again ChatGPT has gained 1 more point.

How to extend 16 TB ext4 LVM to 24 TB in Redhat Linux?

Again ChatGPT failed in the trick question if you know then you are a good Linux Engineer. The issue is that we can not increase the ext4 partition by more than 16TB. After 16TB we have to use the xfs partition. So running all those commands will not give you any results.

Zero points to our ChatGPT

How to change all new user’s home directory in /newhome when we create users by default in Redhat Linux?

I think ChatGPT is very good at user management, So you can ask any question related to user management and just follow it because we got again the right answer.

One more point to ChatGPT.

Create a bash script to delete files from /tmp folder which is older than 60 days in RedHat Linux.

This is just a simple script but it did a good job. For old system admins who use the “-exec rm -f {} \;” newer versions of the find command introduce -delete. So we can say that ChatGPT knows the new find command.

We have tried a simple bash script you can check with the complex script, if you like this article then we will ask ChatGPT other bash script questions.

We have to give 1 point to ChatGPT

How to restrict the root to delete the specific file?

This time ChatGPT shows us that it is just an AI, we all know we can not restrict root like that this could be possible partially but not 100% secure. The only two ways to restrict root are to change attribute and use SELinux which can also restrict root until the root user figure out what the issue is.

In our case, we will 0 points to ChatGPT. If you want to try and give more points let us know in the comments.

Related : What is Selinux ?

How to Disable Selinux ?

Create an NFS service dependent on /sanstorage mount point in Redhat Linux.

In this answer, we will give .5 marks to OpeAI chatbot because there are some other methods that we are using to create dependency for NFS and other services. That is correct but anyone can disable this service and start nfsd service.

So .5 for this answer.

Result

The final result for our question answer session of ChatGPT has got 5.5/10.

5.5/10

As we have seen ChatGPT is accurate to do simple and basic level quetions. But when we tried some trick question this AI chatbot is unable to give answers. As per our question answer we see for local user mangement tasks we can just copy paste but for other task we need to rely on our knowledge. For for the level 1 Job you can use ChatGPT with little guidence. ChatGPT is still learning let see when it cross L2 and L3 level.

Hope this will give you a good idea about OpenAI chatbot.

HOW TO INSTALL POSTGRESQL (PSQL) IN UBUNTU 16.04

Introduction
In this article we are going to learn How to install Postgresql (psql) in Ubuntu 16.04. Postgresql is a open source database management system. It’s also called as ORDBMS i.e. Object Relational Database Management System. The main developer of Postgresql (psql) is PostgreSQL Global Development Group written the application using C programming language and initially released it’s first version on year 1996 under PostgreSQL License.

The purpose of this application is it stores your data securely in his system called database and user can retrieve the stored data using SQL client application. It’s an cross platform application available for major operating systems i.e. Linux, Unix, Microsoft Windows, Solaris and MacOS. You can download the repository of Postgresql (psql) from Github. There are some limitations has been defined by developer team in Postgresql (psql) i.e. Your table size cannot be more then 32 TB, Maximum field size & row size are 1 GB & 1.6 GB. There is no limitation for database size. You can use unlimited size of database.
For more Information and features of Postgresql (psql) you can visit the official website.
Follow the below steps to install Postgresql (psql) in Ubuntu 16.04

Google Drive, Microsoft OneDrive, box, DropBox and much more from the CLI — The Ultimate Linux Newbie Guide

I used to use insync to access my Google Drive account from the command line because it was reliable, however insync ceased support for their CLI client, so I had to rethink that.

I’ve decided to plop with rclone because it’s flexible, lightweight, it works well and it supports over 40 different filesharing platforms, including the most popular ones: Google Drive, Dropbox, Box, Microsoft OneDrive, Amazon Drive/S3. It also supports SSH/SFTP – which is nice, because it presents files/directories on another server just as if they are local files.

The installation & configuration steps are listed below

Run the installer

Firstly, either download the installer script and run it in one go, or if you are paranoid about doing that sorta thing then download, inspect it and run it when you are ready.

To download and run the install process in one step simply launch a terminal and type:

ajross@raspberrypi:~$ sudo curl https://rclone.org/install.sh | sudo bash

If you’d prefer to inspect the script first then:

ajross@raspberrypi:~$ curl https://rclone.org/install.sh -O
(have a look at install.sh with an editor like vim, then):
chmod 700 install.sh
sudo ./install.sh

Configure rclone (interactive)

All going well, the rclone application should now be installed and ready to be configured for your particular cloud file storage setup. Here’s the steps I followed (choices made in red & bold font)

ajross@raspberrypi:~ $ rclone config
No remotes found – make a new one
n) New remote
s) Set configuration password
q) Quit config
n/s/q> n
name> my_drive (nb you can choose any name you like, don’t use spaces though).
Type of storage to configure.
Enter a string value. Press Enter for the default (“”).
Choose a number from below, or type in your own value
[A list of all the services supported is listed, at the time of writing, number 15 was Google Drive]
Storage> 15
Google Application Client Id
Setting your own is recommended.
See https://rclone.org/drive/#making-your-own-client-id for how to create your own.
If you leave this blank, it will use an internal key which is low performance.
Enter a string value. Press Enter for the default (“”).
client_id> (I left this blank)
OAuth Client Secret
Leave blank normally.
Enter a string value. Press Enter for the default (“”).
client_secret>
(I left this blank)

Scope that rclone should use when requesting access from drive.
Enter a string value. Press Enter for the default (“”).
Choose a number from below, or type in your own value
1 / Full access all files, excluding Application Data Folder.
\ “drive”
2 / Read-only access to file metadata and file contents.
\ “drive.readonly”
/ Access to files created by rclone only.
3 | These are visible in the drive website.
| File authorization is revoked when the user deauthorizes the app.
\ “drive.file”
/ Allows read and write access to the Application Data folder.
4 | This is not visible in the drive website.
\ “drive.appfolder”
/ Allows read-only access to file metadata but
5 | does not allow any access to read or download file content.
\ “drive.metadata.readonly”
scope> 1
ID of the root folder
Leave blank normally.

Fill in to access “Computers” folders (see docs), or for rclone to use
a non root folder as its starting point.

Enter a string value. Press Enter for the default (“”).
root_folder_id> (I left this blank)

Service Account Credentials JSON file path
Leave blank normally.
Needed only if you want use SA instead of interactive login.

Leading `~` will be expanded in the file name as will environment variables such as `${RCLONE_CONFIG_DIR}`.

Enter a string value. Press Enter for the default (“”).
service_account_file>
(I left this blank)

Edit advanced config?
y) Yes
n) No (default)
y/n> n
Use auto config?
* Say Y if not sure
* Say N if you are working on a remote or headless machine

y) Yes (default)
n) No
y/n> n (I did this because I was on a raspberry pi which was not attached to a monitor, you may wish to use Y if you are running X and can see graphical output on the display of the machine you are configuring).
Verification code

Go to this URL, authenticate then paste the code here.

https://accounts.google.com/o/oauth2/auth?access_type=offline&client_id(full url suppressed)

Enter a string value. Press Enter for the default (“”).
config_verification_code> (I pasted the code I got from Google from going to the above URL)
Configure this as a Shared Drive (Team Drive)?

y) Yes
n) No (default)
y/n> n
——————–
[my_drive]
type = drive
scope = drive
token = {“access_token”:-omitted-“}
team_drive =
——————–
y) Yes this is OK (default)
e) Edit this remote
d) Delete this remote
y/e/d> y
Current remotes:

Name Type
==== ====
my_drive drive

e) Edit existing remote
n) New remote
d) Delete remote
r) Rename remote
c) Copy remote
s) Set configuration password
q) Quit config
e/n/d/r/c/s/q> q
ajross@raspberrypi:~ $

Check the synchronisation of your data

Although the configuration is now complete, you still need to check the synchronisation of your data:

ajross@raspberrypi:~$ rclone ls my_drive:

Note that the colon (:) is required. The name ‘my_drive’ is the name you supplied earlier during the configuration. All going well, after a few moments you should start to see the list of all your Google Drive (or whatever) files go whizzing by on the display. If you have any issues, just run that command again.

Mount your drive

If all of your files seem present and correct, now it’s time to mount your drive. To do that, make a directory in your home folder to mount it to, and then issue the appropriate mount command:

ajross@raspberrypi:~$ mkdir -p ~/google_drive

ajross@raspberrypi:~$ rclone mount my_drive: ~/google_drive –vfs-cache-mode writes

Depending upon the amount of stuff you have stored, this will take some time do to the initial synchronisation. Feel free to put this task in the background if you like (CTRL-Z and then type bg [RETURN]).

Startup on boot

If you always want to ensure that rclone is running and syncing your content, then you will want to set up the service on boot. You can do this like this:

sudo vim /etc/rc.local

— put the following line in above the line that says ‘exit 0’: —

rclone mount my_drive: /home/<user>/google_drive –vfs-cache-mode writes

Replace my_drive: with whatever drive name you configured and also change <user> with your username.

Done!

That’s it, all going well, you should be able to ‘cd’ into your /home/user/google_drive directory and all your stuff should start appearing in there!

Supported file storage service providers

As of the time of writing, forty-three file sharing services are supported. Here’s the full list:

rclone.org also notes that there are many others, built on standard protocols such as WebDAV or S3, that work out of the box.

Using sar Command in Linux to Get System Resource Stats

Using sar Command in Linux to Get System Resource Stats

It is said that information is power, and the sar Linux command can give you tons of useful information about your system.It is named like that for System Activity Reporter (SAR), and allows you to query information to your system, to understand what is happening or what has happened in the past.It runs in the background gathering your system information as a daemon, writing the current day to text files and converting these to binary files as midnight passes.The best thing is that it stores the data. So unlike top and many other system monitoring commands, you can get a historical view of system resource utilization.This is helpful when you want to see if a performance deterioration matches with the high resource usage at the time.Installing sar commandThe sar command comes in the sysstat package, which normally will not come by default in Debian or RedHat based distros, so you will have to install it first.sudo apt install sysstatOnce this package is installed, you need to start sar service, by doing:systemctl start sysstat.serviceThis will start the service, which you can easily check if it is running by doing:systemctl status sysstat.serviceAnd you will see results similar to this:Using sar command to get system detailsNow that you have the sar running in the background and collecting the stats, let’s see how you can access that information.💡By default, SAR captures a snapshot of system resource usage every 10 minutes. You should be able to get some good information after some hours of it being activated as a service.CPU StatsTo check the CPU resource, run the sar command with -u option:sar -uIt will show the CPU stats collected for the day.11:50:00 AM CPU %user %nice %system %iowait %steal %idle
12:00:01 PM all 16.22 0.52 3.83 0.44 0.00 79.00
12:10:01 PM all 9.19 0.00 2.15 0.21 0.00 88.45
12:20:01 PM all 11.73 0.06 2.70 0.30 0.00 85.21
12:30:01 PM all 6.03 0.00 2.04 0.16 0.00 91.76
12:40:01 PM all 1.43 0.00 0.44 0.15 0.00 97.98

01:00:01 PM all 9.10 0.00 2.51 0.21 0.00 88.18
01:10:01 PM all 11.96 0.00 2.81 0.28 0.00 84.95
Average: all 9.28 0.07 2.35 0.25 0.00 88.04You can also ask sar to show you usage at a different time interval.Let’s say you want to watch and monitor the CPU usage stats for 3 times at an interval of 7 seconds:sar -u 7 3It will give you 3 snapshots, taken in the period requested, and an average of those numbers obtained in all snapshots.You can see it gives you the percentage of usage, the percentage of “nice”, the percentage used by the system, the percentage of IO wait, the percentage of steal and the percentage idle.If desired, you can even ask it about specific CPU usage like this:sar -P 1 1 3Check mounted file system usageThe sar command can also give you a lot of information about your File System. In this example, I am going to request information about the filesystems mounted in the system 4 times in intervals of 2 seconds:sar -F 2 4It will not only give you the number of megabytes used and free but also inform you about the inodes free and used and the file system location.Network report is also availableYou can get a lot of information about your network, for example: network interface, network speed, IPV4, TCPV4, ICMPV4 network traffic and errors.sar -n DEV 1 3 | egrep -v loGetting historical statsYou can obtain historical stats by quering the sar command with a specific timeframe. Let’s say you want to know CPU stats from 8 AM to 2 PM for the current day, you would use this:sar -u -s 8:00:00 -e 14:00:00 ConclusionI find it surprising that sar doesn’t provide a utility to display the system resource usage in graphs. If you want that, you can use some third-party tools like sargraph.GitHub – sargraph/sargraph.github.io: SARchart – An opensource version of the tool for viewing Unix SAR data as Charts/GraphsSARchart – An opensource version of the tool for viewing Unix SAR data as Charts/Graphs – sargraph/sargraph.github.ioAs I mentioned at the beginning, the power of sar command is incredible, there are plenty more options to use with it, which will allow you to get a lot more information which is very deep about your system such as: Process, Kernel Thread, I-node, and File Table Details, Swapping Statistics, Messages, Semaphores, and Process Details, I/O Operation Details and much, much more. You can get the list of different options, by running:sar –helpWhich will allow you to see the ser of options the command has to be able to provide deep understanding of the system statistics that can help any administrator to understand what is happening in the system at any moment in time.

Google Extends Linux Kernel Support To Keep Android Devices Secure For Longer

0
Android

Google plans to support its own long-term support (LTS) kernel releases for Android devices for four years, a move aimed at bolstering the security of the mobile operating system. This decision, reported by AndroidAuthority, comes in response to the Linux community’s recent reduction of LTS support from six years to two years, a change that posed potential challenges for Android’s security ecosystem. The Android Common Kernel (ACK) branches, derived from upstream Linux LTS releases, form the basis of most Android devices’ kernels. Google maintains these forks to incorporate Android-specific features and backport critical functionality. Regular updates to these kernels address vulnerabilities disclosed in monthly Android Security Bulletins. While the extended support period benefits Android users and manufacturers, it places significant demands on Linux kernel developers.

Apache Tomcat and Apache HTTP server are two of the most widely used servers in the world of web technologies. Both of these products are developed under the umbrella of the Apache Software Foundation, but they serve different purposes and are suited to different types of projects. In this blog, I’ll dive into the technical details of both, share some real-world examples from an Ubuntu terminal, and discuss my personal experiences with both servers.
What is Apache Tomcat?
Apache Tomcat is an open-source Java servlet container that acts as a web server and provides the environment to run Java code on the web. It is designed to serve Java applications and is equipped with tools to manage Java Servlets, JSPs (JavaServer Pages), and several other Java technologies. Tomcat is the go-to choice for developers looking to deploy and manage Java applications.
Setup on Ubuntu
To install Tomcat on Ubuntu, you typically need to install Java first, then download and set up Tomcat. Here’s a quick run-through:
# Install Java
sudo apt update
sudo apt install default-jdk# Download Tomcat
wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.54/bin/apache-tomcat-9.0.54.tar.gz

# Extract and set up Tomcat
tar -xzf apache-tomcat-9.0.54.tar.gz
sudo mv apache-tomcat-9.0.54 /usr/local/tomcat9

# Start Tomcat
/usr/local/tomcat9/bin/startup.sh
You can then access the Tomcat server at http://localhost:8080. The output should show the default Tomcat homepage.
What is Apache HTTP server?
The Apache HTTP server, commonly known as Apache, is a robust, commercial-grade, open-source web server managed by the Apache Software Foundation. It handles HTTP requests and serves static and dynamic web content. Apache is highly customizable through a rich selection of modules and is known for its power and flexibility.
Setup on Ubuntu
Installing Apache on Ubuntu is straightforward:zaw
# Update packages and install Apache
sudo apt update
sudo apt install apache2# Ensure it is running
sudo systemctl status apache2
After installation, you can visit http://localhost in your browser, and you should see the default Apache2 Ubuntu default page.
Comparison of features
While both are excellent in their respective fields, here are some detailed comparisons:
Use cases
Apache Tomcat:

Best suited for Java applications such as JSP and servlets.
Commonly used in conjunction with Apache HTTP server, which handles static content, while Tomcat handles dynamic content.

Apache HTTP server:

Ideal for serving static websites or as a reverse proxy.
Highly configurable for handling various performance and security tasks.

Performance

Apache HTTP server is generally faster when serving static content due to its ability to manage high loads and its caching configurations.
Tomcat excels in running Java applications, something Apache HTTP server does not natively support.

Configuration
Tomcat’s configuration is centered around server.xml, web.xml, and context.xml files which can be a bit complex to handle initially. Apache HTTP server, with its .htaccess and httpd.conf files, provides a broader, more direct approach which many web administrators find intuitive.
For those who want to dig deep into technical differences, let me cover that as well.
In-depth technical comparison
Core functionality and architecture
Apache Tomcat:

Primary role: Java servlet container and web server designed to serve Java applications (servlets, JSPs).
Architecture: Built around the Java EE specifications for web applications. It uses a series of Java-specific connectors for handling web requests, most commonly the Coyote HTTP/1.1 Connector.
Execution environment: Runs Java bytecode, which allows it to execute servlets and JSPs, converting them into HTML to serve to clients.

Apache HTTP server:

Primary role: HTTP server for serving static content and as a reverse proxy.
Architecture: Multi-processing modules (MPMs) control how client requests are handled, with choices between prefork, worker, and event modules, allowing fine-tuning for handling concurrent connections.
Execution environment: Does not execute Java bytecode natively; designed to serve static files and handle PHP, Perl, or other server-side languages using respective modules.

Performance considerations
Apache Tomcat:

Optimized for Java application performance. It handles thread allocation based on requests and supports non-blocking IO with its NIO (Non-blocking Input/Output) connector.
Scalability can be managed via Java virtual machine (JVM) tuning and connectors configuration for optimal response time and memory management in high-load environments.

Apache HTTP server:

Superior performance when serving static content due to its ability to leverage caching (mod_cache), gzip compression (mod_deflate), and fine-tuned configuration for handling TCP connections efficiently.
The event MPM allows Apache to handle thousands of connections in a more memory-efficient manner than traditional threaded or process-based approaches.

Configuration and management
Apache Tomcat:

Configuration Files: Mainly uses server.xml for global configuration, web.xml for application-specific settings, and context.xml for context configurations.
Management: Offers a built-in web-based admin tool for server management and configuration. Logging is handled via Apache Commons Logging, log4j, or SLF4J.

Apache HTTP server:

Configuration Files: Uses httpd.conf for server configurations and .htaccess files for directory-level configuration.
Management: Configuration changes often require a server restart or reload. It supports extensive logging options configurable through mod_log_config.

Security features
Apache Tomcat:

Provides security realms for authenticating user identities, secure socket layer (SSL) configuration for HTTPS, and a comprehensive security manager to enforce access controls.
Common vulnerabilities usually relate to Java deserialization, cross-site scripting, and misconfiguration.

Apache HTTP server:

Robust mod_security module that acts as a firewall to block common web attacks.
Supports SSL/TLS configuration, and the ability to implement strict access control rules (via .htaccess or httpd.conf).

Personal experience
From my experience, I find Apache HTTP server to be incredibly robust for static sites and as a reverse proxy. Its wide adoption and vast community support make finding solutions to problems relatively easier. However, its configuration can be daunting for beginners.
On the other hand, Tomcat feels like a breeze when you’re deep into Java development. It’s almost indispensable in certain Java environments. Yet, its Java-centric nature might not appeal to those not using Java technologies.
Conclusion
Choosing between Apache Tomcat and Apache HTTP depends heavily on your project’s needs. For Java applications, Tomcat is indispensable, whereas for high-performance, high-traffic static sites, Apache HTTP server is the way to go. In many enterprise environments, you’ll find both being used in tandem to leverage the strengths of each.
I hope this comparison helps you understand where each server excels and where it might fall short. As always, the right tool for the job depends on the job itself!

Reminders Is A GTK4 To-Do List App That Syncs With Microsoft To Do

Reminders is a simple, GTK to-do list application for Linux. The application was recently updated with support for syncing with Microsoft To Do (beta), the ability to create and edit task lists, and more.The application was originally called Remembrance, and it had it first stable release less than a month ago. It comes with a responsive user interface using GTK4 and libadwaita, and right now (including the latest release), Reminders features:Add tasks (called reminders in the app) with a short descriptionCreate and edit task listsTask remindersRecurring remindersDisplay desktop notifications, a notification badge using e.g. Dash to Dock, and optionally play a sound when a task is dueSort tasks by due date/time or titleSearch tasksSupport for syncing with Microsoft To Do (beta), with the ability to sync all or only some task lists, and set the auto-sync intervalReminders responsive main UI, new reminder UI and Dash to Dock icon notification badgeThe recently added support for syncing with Microsoft To Do is currently marked as a beta feature, and it doesn’t support all the features provided by the Microsoft To Do web interface / apps.With Reminders version 2.0 / 2.1, you’ll be able to sync the task lists, task description / notes and the task reminder. It does not support synchronizing the task due date, category, file attachments, task steps, or the ability to repeat a task.While not being a complete GUI for using Microsoft To Do on Linux, Reminders is great if you want to quickly add simple tasks from your Linux desktop using a native (GTK) application, and sync them with say the Microsoft To Do app running on your phone. And maybe its Microsoft To Do compatibility will improve with future releases.The Reminders developer also looked into getting the application to sync with Google Tasks, but decided against it because its API doesn’t support setting task times. Besides, there’s already a GNOME application that syncs to-do lists with Google Tasks—GNOME To Do (Endeavour).You might also like: To-Do App With Built-In Timer “Go For It!” Updated With Pomodoro Timer, Configurable ShortcutsInstall RemindersThe easiest way to install Reminders on Linux is to use its Flatpak package, available on Flathub. With Flatpak installed and Flathub enabled (quick setup guide here), you can install Reminders using the command below:flatpak install flathub io.github.dgsasha.RemembranceAlternatively, you can build it from source, as explained on its GitHub page.

Stay anonymous while hacking online using TOR and Proxychains

In this tutorial we will guide you how to stay anonymous while hacking online using TOR and Proxychains. Hiding your ass while hacking is easy just require some configuration which we will gonna see in this tutorial. Just follow this as shown.
First thing First!!!!

TOR

Tor is software and an open network that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy. It gives you access to the dark web.

Dark web is nothing but the encrypted network that exists between tor servers and their clients.

For more detail : https://www.torproject.org/

PROXYCHAINS

A tool that forces any TCP connection made by any given application to follow through proxy like TOR or any other SOCKS4, SOCKS5 or HTTP(S) proxy. 

Supported auth-types: “user/pass” for SOCKS4/5, “basic” for HTTP.

Lets start!

STEPS:

1. Open kali linux terminal and type

root@kali:-# sudo apt-get install tor proxychains

root@kali:-# sudo service tor start

root@kali:-# gedit /etc/proxychains.conf
Go to http://proxylist.hidemyass.com/ . Select one ip and add as shown :

root@kali:-# proxychains wget http://ipinfo.io/ip -qO-

That’s it! Now you can use proxychains with any sort of command. Example:
root@kali:-# proxychains sqlmap -u http://www.sqldummywebsite.com/cgi-bin/item.cgi?item_id=15 –dbs
