How to Install and Run Redis Directly on macOS (Without Homebrew)

Abdussalam Mujeeb-ur-rahman — Tue, 07 Jan 2025 00:02:25 +0000

To install Redis without using Homebrew on my macOS, I had to build it from source. Here’s how I did it:

I installed Xcode Command Line Tools by running (in my terminal):

    xcode-select --install

I downloaded the Redis Source Code by running:

    curl -O https://download.redis.io/releases/redis-6.2.11.tar.gz

You can always check Redis releases to download any of your choice.

I extracted the file I downloaded by running:

    tar -xvzf redis-6.2.11.tar.gz
    cd redis-6.2.11

I did run the make command to compile Redis:

    make

After the build and compilation was executed successfully, I proceeded to installing Redis:

 sudo make install

I started the Redis server manually:

 redis-server

I opened another terminal and connected to the Redis server by running the following:

 redis-cli

To verify it was working, I did run the PING command:

PING

As expected, I got the PONG response.

I hope it helps. Thanks for reading 😊

Link Your Github Account To Your Terminal Through SSH

Linking your GitHub account to your terminal can greatly streamline your workflow, allowing you to seamlessly push and pull code without the need to repeatedly enter your credentials.
By establishing this secure connection, you enhance both efficiency and security in managing your projects.

Me: In this article, I'll walk you through the simple steps I took in setting up SSH authentication between my Kali Linux system and my GitHub account.
Nobody: What of Windows' users?.
Me: Windows' users can also follow my lead, but I will like them to use git bash as the command line.

Without further ado, let's jump into the game!.

Firstly, you need to generate an ssh key, and you can do that using the following command in your terminal:

ssh-keygen -t rsa -b 4096 -C your_email@example.com

replace your_email@example.com with your email address (must be the one associated with your Github account).

Secondly, save the ssh key. By default, the ssh key files are saved in the ~.ssh directory. So, you can press enter to accept it or you can decide to change the location.
You will be prompted to enter and re-enter a passphrase which you can ignore by press enter immediately. Your key has been generated.

Thirdly, you need to add the new generated key to the ssh-agent (manages your ssh keys). So start the ssh-agent by running the command:

eval "$(ssh-agent -s)"

Now, add your ssh private key to the ssh-agent by running the following command:

ssh-add .ssh/id_rsa

.ssh/id_rsa is the location of the private key from my current position in my terminal. Make sure you locate yours correctly.

Fourthly, Add the key to your github account.
Go to the .ssh folder, then locate and open id_rsa.pub in a text editor. Copy whatever is in there.
Note: if you can't locate it, just run cat ~/.ssh/id_rsa.pub | pbcopy. It copies the content and put it in your clipboard.

Now, let's paste it in our github.
Go to settings,

Go to SSH and GPG keys,

Click on New SSH Key button,

Give it a title (example - Linux SSH key), The Key type is Authentication Key, paste what you copied in id_rsa.pub in the Key field.
Your result will be similar to this.

Now, let’s test the connection.
Run the following command in your terminal:

ssh -T git@github.com

If everything is done correctly, you see a similar message:

Hi username! You've successfully authenticated, but GitHub does not provide shell access.

But, some error like this might occur:

You will need to get the private key and input it instead of typing yes when asked if you want to continue connecting.
To get the private key, you can run the command:

ssh-keygen -lf .ssh/id_rsa

You will get something like

4096 SHA256:zjb3ddSf4AhvjyJdYDS4UqX+G0seY your_email.com (RSA)

Copy everything except 4096 and (RSA). And that’s the private key.
And you're good to go.

Now I am able to perform Git operations on repositories for which I am authorized.

Thanks.I hope it's helpful.

Resolve “Hash sum mismatch” error when running `sudo apt-get update` in Kali linux 2024.1

Abdussalam Mujeeb-ur-rahman — Mon, 01 Apr 2024 08:12:59 +0000

Encountering a Hash sum mismatch error during the execution of sudo apt-get update in Kali Linux can be attributed to various factors. These factors encompass network issues, repository problems, syncing errors, outdated repositories, package management system anomalies, package corruptions, software upgrades, disk issues, package verification discrepancies, and security measures such as proxy or firewall settings.

So, I encountered this error and I tried so many possible solutions. These included ensuring a stable internet connection, clearing the apt cache, temporarily disabling the firewall, and exploring other network-related adjustments.

I stumbled upon a solution, which helped solve the problem.
This was how I solved the issue:

Firstly, I paid a visit to Kali's official mirror site. I scrolled down and I saw something like in the image below.

I needed to view the closest mirror. And I scrolled down and saw this.

The closest to me seemed to be http://kali.download/kali/. So, I then decided to change my mirror link to it.

Now, the next question is, how did I view and change my mirror link?.
Firstly, run sudo su in your terminal to switch to the super user mode.
Then, run nano /etc/apt/sources.list to access the mirror link. You will see something like this

Change only the link in the second line to the nearest mirror link you got. As you can see, I already changed it.
Then run sudo apt-get update again.
I hope this helps.
Thanks.
