Generally, you can check the version of the Linux operating system via the ‘uname’ command. This command prints out all the information about your system. It can be accessed via the /etc/os-release file and will display the kernel architecture, name and release information. This command can also be executed from the desktop, but the steps depend on your operating system and desktop environment. Here are the basic steps to check the version of Linux.

First, you can use the ‘uname’ command to find the version of Linux kernel. The ‘uname’ command is also available for Ubuntu and CentOS. The output of this command will display the OS name, major version, and asynchronous release number. You can also use the ‘hostnamectl’ command to check the Linux kernel system’s version. By using these commands, you can determine the version of your OS.

Another way to check the Linux version is through the ‘lsb_release’ command. This command displays data about the LSB modules on your computer. It will also list the distributor’s ID and release number. This command is very easy to use and will give you more information about the version of the Linux operating system. This command is a great way to check the version of your OS if you’re not familiar with it.

To find the exact Linux version of your system, you can use the lsb_release command. This command prints out all the details related to your Linux distribution’s release version. You can even fine-tune the output to get more detailed information. The lsb_release command is particularly useful if you are using a systemd-based OS. You can also find out the name of your distro and its version using this command.

Several third-party tools and built-in commands allow you to check the Linux version of your system. Since Linux packages are often created with a specific version of the operating system, knowing your system’s version is essential for troubleshooting errors and unexpected behaviors. This is especially important when installing new Linux distros. Once you know the version of your system, you can install new packages without any problems.

The first step is to use the lsb_release command to check for LSB module availability. Using this command will help you resolve no LSB module errors. You can also try the nc command, also known as net cat. This command can be used to test the TCP connection between two machines. The server must be running on port 3333. To test a TCP connection between two systems, use nc as a server.

If you’re wondering how to check the Linux version on your system, you’ve come to the right place. There are commands you can run to do just that. Regardless of the OS you’re running, these command-line tools will reveal the latest version. Linux’s user input is entered into shells, which are the interfaces between the system and its users. Shells are run through the graphic terminal, and they process the commands you type in them. For example, the lsb-release command shows the version of the Linux kernel installed on the system.

Depending on the distribution and support for your system, the output from these commands will vary. If you have a CentOS or Ubuntu machine, the command line will reveal the distribution, major release version, and other specifications. Use a different command for Ubuntu and CentOS if you need to check the exact version. You can also try the lsb-release command to find out if you have a compatible version of LSB modules.

You can use the uname command to check the system version and other information. Uname can print the name, version, and manufacturer. Other information, such as the system’s codename, can be found in the /etc/issue and /etc/*release files. These files are generally found in older release versions of the Linux system. Some of these commands have dependencies on the Linux distribution, so you should read the comments and other documentation before using them.

The netcat command is a popular network monitoring utility which displays information on the state of open ports on a network. The utility is a useful tool for network administrators, who can use it to identify network activity and open ports in Linux systems. It should be available on most modern Linux distributions. However, before using this tool, it is important to read its documentation thoroughly. This article will discuss the features of netcat and give some basic instructions on how to use it.

The cat command displays information from files ending in’release’ in /proc directory. The output will also include the name of the distro and version. The cat command is an easy way to find out the exact version of Linux on your system. There are many ways to determine the version of your operating system. To make sure your installation is up to date, you can use the cat command to display the information.

  • ‘nc’ command

If you use Linux as your operating system, you should learn how to check the Linux version from the command line. There are several ways to get this information, including the use of command-line utilities. Most operating systems will display this information in their system settings. Some systems also show other details like kernel and service pack versions. So, it’s important to find out the exact version of your operating system before you make any changes.

To check your system’s version, you can use the ‘uname’ command, which prints out the information related to your system. You can also check the /etc/os-release file to see the exact version number of your system. Some commands are dependent on the Linux distribution, while others are not. For example, the ‘hostnamectl’ command displays the name of the computer and its current name and release.

The os-release file is a special file used to report system details. It will vary depending on the distro you’re running, so you should check out the examples to see what to expect. If your system uses systemd, you should try ‘lsb-release’ to see the LSB info. It’s a useful tool to use for troubleshooting.

How to Copy and Rename a File in Linux : Linux users can use various commands to rename, move, and copy files. They can also use wildcards to move files to new locations. This article will show you how to copy and rename a file. Listed below are the main commands you can use to copy and rename files in Linux. Once you have them mastered, you can move files and directories in a snap.

How to copy-file renames file old as new :

There are many reasons why you may want to rename a file. Renaming a file can result in a change in meaning. Adding another name to a file creates a hard link, so any future attempts to open the new file will refer to the new name. The problem with this method is that the new name must be in the same file system as the old file. It also only works on MS Windows Vista.

Linux users have long been familiar with the simple mv and cp commands, but you might not be familiar with the rename command. Mv and cp were some of the first commands that most people learned how to use, but the rename command offers some unique options. Here are the steps you should follow to rename a file. Use the ls command to verify that the file is actually renamed.

Steps to make-symbolic-link creates a symbolic link named new :-

To create a symbolic link, you must know how to use the ln command in Linux. The ln command creates a link to a file, pointing to it in the current working directory. This command does not produce any output, so there is no way to know whether it succeeded or not. On the other hand, you can see whether it creates a new file or just renames the current one.

To create a symbolic link for a file, first find the file to be copied. In a file system, a file with the same name is copied by a symbolic link. Then, make sure that the file has the same name as the one that you want to rename. In linux, the file that you want to copy must be in the same directory as the file you want to rename.

When renaming and copying a file, a symbolic link should be named new, as it is not always possible to rename a file that already exists. However, this is the easiest way to rename a file, and it is a powerful feature for Linux users. But if you have a file that you don’t want to rename, use the -x switch instead.

Some mv command enables you to move files :-

If you want to rename a file and move it to a different directory, the mv command is your friend. It’s easy to use and can rename any file or directory on your computer. It requires that you have write permission on the source and destination files. You can even rename files inside the same directory. When using the mv command, make sure that you have write permissions on both sources and destinations.

You can use the mv command to move multiple files or directories at once. The -t option is useful if you want to move many files at once. Using the mv command, you can move files in both directions by specifying a wildcard. You can also use the -x option to move a single file to a new directory.

Mv command enables moving files in linux. It replaces a file with the same name in the destination. In case the mv command encounters a file with the same name, it will append the name of the source file with a single. You can also switch to interactive mode to prevent accidental overwrites. In this mode, the mv command will ask for confirmation before moving a file, unless the source file name has already been changed.

The mv command allows you to move files between directories and files. It also renames files. However, you should be aware that the mv command may overwrite many existing files. So, if you need to move several files to different directories, make sure to use the -MIR option to avoid overwriting a file. If the mv command does not prompt for confirmation, it overwrites existing files without asking for confirmation.

v command enables moving files in linux successfully. The mv command has simple syntax and optional safety flags. Almost all Linux distributions support mv. Before you run the command, make sure to specify the source and destination. The source and destination files must be in the same directory. Then, you must specify the destination folder in the Select Destination window.

The mv command is a powerful tool that allows you to move files between directories. By using this command, you can change the name or path of a file. When you move a file, you don’t actually move the data, but rather change the name and path of the file object. The file’s permissions remain unchanged. So, make sure to read the documentation carefully before using this command.

How to install tor browser in kali linux?

how to install tor browser in kali linux,how to install tor in kali linux,how to install tor in kali linux github
how to install tor browser in kali linux,how to install tor in kali linux,how to install tor in kali linux github

How to install tor browser in kali linux : To install the Tor browser in Kali Linux, you will first need to change the default user model. The default user for Kali Linux is root, but in 2020.1, Kali Linux will create a non-root user for you, which will be sufficient for running Google Chrome and most of this guide. You will also need the torbrowser-launcher package, which is part of Debian and will install Tor in a GUI.

  • Onion routing is a peer-to-peer (P2P) overlay network :-

The Tor browser is an open-source, peer-to-peer overlay network in Kali Linux that handles network traffic via proxy nodes. With Tor, users can use special “.onion” urls to access the “Dark Web”. These urls are constantly in motion and contain many unindexed and non-searchable web pages. Using them may also be illegal.

Tor Browser is designed to protect your identity and content from being monitored by anyone. The Tor browser protects your privacy by encrypting your data at every level of the application and communication protocol stack. When you browse the web, the Tor network routes your traffic through a network of successive relays, each relay decrypting the previous layer and revealing the next one. This way, when someone tries to spy on you, they’re not able to track your activity.

Without Tor Browser, you can use the dark web to access the dark web and steal sensitive information. While this may be tempting, you’re better off not doing so. The Onion routing project was originally developed in the mid-1990s to secure U.S. intelligence community online communication. The team of researchers behind the project were computer scientists and mathematicians.

  • Tor browser resists fingerprinting ensure your online security:-

Using the Tor browser to browse the Internet is an important step in ensuring your online security. While the browser is designed to reduce the footprint of your web browsing activities, some features can compromise your security. For example, if you use it on a Windows computer, you should turn off the NSA’s enhanced NSA edition to protect your privacy. In addition, you should avoid typing directly into the Tor browser by using a notepad instead of copy and paste. The latest fingerprinting techniques can match your typing cadence uniquely after ten minutes, so it’s best to use a browser that resists fingerprinting.

The Tor Browser has a lot of security benefits. By isolating the websites you visit, you are not followed by third-party trackers or advertisements. As all traffic is encrypted three times, fingerprinting is next to impossible. The browser is even capable of opening websites that are blocked by your home network. The Tor Browser also offers multi-layer encryption and fingerprint resistance. To install it on your Kali Linux computer, follow the instructions provided below.

  • It is legal to install Tor browser in Kali linux ?

You may be wondering if it is legal to install Tor browser in Kali linux. After all, it is possible to install a VPN and other security software that will protect you from malicious websites. It is also possible to access the dark web, which is where the most criminal activity is concentrated. Although it is possible to use standard web search engines to search for information, the Tor browser is a better choice if you want to be completely anonymous while surfing the internet.
Firstly, you must know that Tor Browser is a modified version of Firefox, so you must ensure that you are running the browser as a non-root user. You can run the Tor browser by running ‘top’ or ‘htop’ as a non-root user. If you are running the browser as the root user, you may encounter errors such as ‘display not available’ or ‘GTK is not enabled’. After downloading the Tor browser, you must install it on a valid computer or VM. To install Tor, you must use the right user name and password for the VM. You must also make sure that the VM is a legitimate copy of Kali Linux. If you are using Kali Linux on a laptop or desktop, you must have administrator privileges to install the operating system. To install Tor, open the download folder of Kali Linux and click on “open in terminal”. After this, you should see the path

Besides being an open-source operating system, Kali Linux also has a wide variety of security benefits. You can easily find information about Kali Linux’s security capabilities by consulting a knowledgeable hacker or security expert. There is no need to be a computer science graduate to use this operating system, as it has a wealth of security benefits. Unlike popular operating systems, which are primarily designed to harvest user information, Kali was built with security in mind.

How To Change HBA Port Speed In Linux?

How To Change HBA Port Speed In Linux?

Keeping up with the ever-increasing demands of today’s data centers is challenging. While modern IT infrastructures are built on open-source software and cloud services, hardware acceleration remains key to streamlining data center operations. The high frequency of modern servers and the accelerating speeds of SSDs require optimized communication between devices.

For example, host bus adapters (HBAs) are a commonly used component in data centers because they allow computer servers to communicate with target devices that lack network or operating system interfaces (such as SSDs or tape libraries).

After all, without HBAs, a computer server would need an additional network card for each target device it wanted to access. In this blog post, we’ll show you how to configure HBA port speed in Red Hat Enterprise Linux (RHEL).

What’s the role of an HBA in a data center?

Host bus adapters are a critical component in the communication pathways of data centers. A computer’s network interface card (NIC) can only reach so far, meaning that a server would need an additional NIC for each device that it wants to access.

A host bus adapter allows a server to connect to devices that lack network or operating system interfaces. While it may not sound like much, this small, yet crucial, piece of the hardware enables servers to communicate with a variety of devices, including storage and networking hardware, iSCSI, FCoE, and Fibre Channel devices.

An HBA might be used to transfer data between a server and an Ethernet storage device (such as a storage area network (SAN), Network-Attached Storage (NAS), or a tape library).

Configuring HBA port speed in Linux

Configuring HBA port speed in Linux

Host bus adapters are commonly used in data centers. Although most HBAs have been designed for 10/100/1000BASE-T Ethernet networks, they can also be used with other network types.

Some factors to consider when configuring the port speed of an HBA include the network bandwidth of the devices to which it’s connecting, the type of switches in the network, and the capabilities of the server’s CPU.

For example, you might want to configure the port speed of an HBA to 10GBASE-T to connect to a device with a high bandwidth requirement, such as a Fibre Channel device or an Ethernet switch.

To change the port speed of an HBA, follow these steps:

  • First, you need to identify the HBA on your system and its driver. Although the HBA port speed can be changed from the HBA driver’s default setting, the driver might not support the new setting.
  • Then, you need to find the correct driver for the HBA. Drivers are available in the Linux kernel and are used to communicate with the HBA.

HBAs and their importance in data centers

The high frequency of modern servers and the accelerating speeds of SSDs require optimized communication between devices. Host bus adapters are widely used between servers and these devices to enable communication.

The speed of data transmission between these devices is important for the efficient operation of data centers. The increasing popularity of data centers has created a need for HBAs with higher transmission speeds to support increased data storage and data transfer rates.

When it comes to HBA transmission speed, there are currently two commonly used standards: 1000BASE-T (or just 1000BASE) and 10GBASE. These standards are used to specify the transmission speed of 10BASE-T and 10GBASE Ethernet networks.

Limitations of current HBA speeds

While current HBAs with a 10GBASE Ethernet transmission speed allows for data transmission at 10 gigabits per second. These HBA speeds don’t take full advantage of the advanced network equipment available in modern data centers.

However, some of the latest equipment, including 10GBASE Ethernet switches, support 40 gigabits per second (Gb/s) Ethernet transmission speeds. While HBAs with a 10GBASE Ethernet transmission speed can be used to connect to network equipment with a 40Gb/s Ethernet transmission speed. The connection is limited to 10 gigabits per second.

Host bus adapters with a 10GBASE-T Ethernet transmission speed can be used with network equipment that supports the IEEE802.3bz standard. Including 10GBASE Ethernet switches that use the IEEE802.3bz standard. Currently, the IEEE802.3bz standard is supported by a limited number of network equipment manufacturers.

How to configure HBA port speed in Linux?

To change the port speed of an HBA, follow these steps:

First, you need to identify the HBA on your system and its driver. Although the HBA port speed can be changed from the HBA driver’s default setting. The driver might not support the new setting.

Next, you need to find the correct driver for the HBA. Drivers are available in the Linux kernel and are used to communicate with the HBA.

How can you increase HBA speeds in Linux?

How can you increase HBA speeds in Linux?
How can you increase HBA speeds in Linux?

You can increase the HBA speeds by configuring the driver to support the 10GBASE-T Ethernet transmission standard.

However, currently, the 10GBASE-T transmission standard is supported by several Ethernet drivers, including the Intel e1000e driver (used by Intel Ethernet SFP+ adapters), the Intel ixgbe driver (used by Intel 10Gb SFP+ adapters), the VIA Networking Technologies VN-Net 10G driver, the Chelsio T5 driver, and the Chelsio T6 driver, and the Generic Driver for Ethernet Networking Devices.

While the HBA port speed can be changed from the HBA driver’s default setting. The driver might not support the new setting. Before you change the port speed of an HBA, you must first determine whether the HBA and its driver support the new port speed.

Final words: A word of caution

In short, the increasing popularity of data centers has created a need for high-speed host bus adapters to support higher data transfer rates. In addition, host bus adapters with a 10GBASE-T Ethernet transmission speed. Also, it allows for data transmission at 40 gigabits per second, providing a significant boost in performance.

After all, with the increased demand for data services, along with the need for high-speed transmission, it’s important to keep an eye on the latest HBA technologies and how they can be used to improve data center operations.

How To Harden Linux Mint?

How To Harden Linux Mint?

There are various ways to harden Linux Mint. Many users recommend installing and using YaST or the mint-update command-line utility. Others recommend creating a passwordless sudo user, disabling root login, and running security updates and antivirus software.

Linux Mint is one of the most popular distributions of Linux. It is based in Ubuntu, but with a different desktop environment and some other differences.

One of the advantages of Linux Mint is that it is relatively easy to install and use. However, this also means that it is not as secure as some other distributions. In this article, we will show you how to harden Linux Mint so that it is more secure.

Before we start, we should mention that hardening Linux Mint is not a silver bullet. It will not make your system completely secure.

However, it will make it more difficult for attackers to compromise your system.

Use a strong password

This is probably the most important thing you can do to secure your system. Make sure to use a strong password for your user account and the root account. A strong password is at least 8 characters long and contains a mix of upper and lower case letters, numbers, and special characters.

Install a firewall

A firewall is software that allows or blocks network traffic based on a set of rules. By default, Linux Mint does not come with a firewall installed. However, it is very easy to install one.

We recommend using the UFW (Uncomplicated Firewall). To install it, open a terminal and type:

sudo apt install ufw

Once it is installed, you can enable it by typing:

sudo ufw enable

Keep your system up to date

One of the most important things you can do to secure your system is to keep it up to date. New security vulnerabilities are discovered all the time. By keeping your system up to date, you can make sure that these vulnerabilities are patched as soon as possible.

To update your system, open a terminal and type:

sudo apt update && sudo apt upgrade

Use encrypted disks

If you are using Linux Mint on a laptop, it is a good idea to encrypt your disk. This way, if your laptop is stolen, the data on it will be much more difficult to access.

To encrypt your disk, you can use the LUKS (Linux Unified Key Setup) system. To encrypt your main system drive, you will need to use the command line. However, there is a graphical tool that can be used to encrypt other drives, such as USB drives.

Use a VPN

A VPN (Virtual Private Network) is a way to encrypt your internet traffic and route it through a server in another location. This can be useful for many reasons, including security and privacy.

There are some different VPN software that you can use on Linux Mint. We recommend using OpenVPN. To install it, open a terminal and type:

sudo apt install openvpn

Once it is installed, you can connect to a VPN server by following the instructions on the OpenVPN website.

Disable unnecessary services

If a service is not being used, it is a good idea to disable it. This way, it cannot be exploited by an attacker.

To list all the services that are running on your system, open a terminal and type:

sudo systemctl list-units --type=service

This will list all the services, along with their status. To disable a service, type:

sudo systemctl disable [service name]

Use AppArmor

AppArmor is a security system that can be used to restrict the capabilities of programs. This can be useful for preventing malicious programs from doing things that they should not be doing.

AppArmor is not installed by default on Linux Mint. However, it is available in the repositories. To install it, open a terminal and type:

sudo apt install apparmor

Once it is installed, you will need to configure it. The AppArmor website has a good tutorial on how to do this.

Use a security-focused browser

There are several different browsers that you can use on Linux Mint. However, not all of them are created equal when it comes to security.

We recommend using the Tor Browser. It is based on the Firefox browser and is designed to provide a high level of security.

To install the Tor Browser, open a terminal and type:

sudo apt install tor-browser

Once it is installed, you can launch it from the menu.

Use a password manager

Above all, a password manager is a software that allows you to store your passwords in a secure location. This can be useful for several reasons, including security and convenience.

Firstly, there are several different password managers you can use on Linux Mint. We recommend using KeePassXC. It is a free and open-source password manager that is available in the repositories.

To install KeePassXC, open a terminal and type:

sudo apt install keepassxc

Once it is installed, you can launch it from the menu.

Conclusion on Harden/Secure Linux mint

So, we have shown you how to harden Linux Mint. By following the tips in this article, you can make your system more secure. However, it is important to remember that no system is completely secure. After all, there is always a risk of being compromised, no matter how secure your system is.

How To Install Linux On Windows Without Admin Rights?

How To Install Linux On Windows Without Admin Rights?

Installing Linux on Windows without admin rights can be a little challenging if you don’t have administrator access to the computer. Most computers come with Windows pre-installed, and it usually requires administrator privileges to install software on it.

However, many users or home users may not have administrator access. If you find yourself in such a position, then you won’t be able to install most versions of Linux on your computer. That said, there are still a few ways that you can work around this issue and get around the restrictions built into Windows so that you can still install Linux on your computer.

In this article, we will look at some of these strategies for how to install Linux on Windows without administrative rights.

Run Linux in a Virtual Environment

One of the easiest ways to install Linux on Windows without administrative rights is to run it inside of a virtual environment. By installing a virtualization program like VirtualBox, you can create a virtual machine and install a virtual version of Linux on that virtual machine.

As long as the virtual machine has the software you need, you can use it to run any program that would normally require administrative access. This includes installing Linux on Windows 10.

One thing to keep in mind is that virtual machines take some time to fully boot, so they might not be the best option if you need to use the computer for other purposes at the same time.

Once the virtual machine is up and running, it should function just like any other computer. You can install software and access files just like you would be able to do on a normal computer. This makes virtual machines an excellent option for installing Linux on a computer with Windows 10.

Install Linux on a USB Drive

Another way to install Linux on Windows 10 without administrative access is to install it directly to a USB drive. While this is perhaps not the most practical solution, it can be helpful in certain situations.

If you just need to install Linux for one specific purpose, a USB drive may be the best solution. In the past, this was a common solution for installing Linux on computers that didn’t have enough CPU or RAM to run Linux properly.

However, modern computers can handle Linux installs just fine, so this is more of a way to work around the restrictions of Windows. As a bonus, you can use the USB drive to boot Linux on Windows 10. This can be helpful if you just need to do one specific thing that requires Linux.

Install Linux Using Windows 10’s Continuum

Continuum is a feature built into Windows 10 that allows you to switch between a desktop computer and a touchscreen-friendly mode. This can be helpful if you’re using a laptop or tablet.

Once you switch to this mode, you can use your computer as if it were a touchscreen computer. You can do things like drag and drop files and open apps. Unfortunately, this mode doesn’t support Linux. Fortunately, you can install Linux in desktop mode, and then switch to Continuum, and it should work just like it did before you installed Linux on Windows 10. This is helpful if you just need Windows to run a few programs.

Just be aware that this method only works for certain Linux distributions. Another option is to use the Windows 10 Subsystem for Linux. This feature allows you to run a full Linux environment on Windows 10. While it isn’t the same as installing Linux, it does give you the full Linux experience without any of the restrictions that come with running Linux on Windows. This feature isn’t available on every version of Windows 10, though.

Install Linux on Windows with Recalbox

Another option is to install Recalbox, an emulation console that allows you to play retro games on your computer. While the emulator is mostly used to play retro games, you can also install Linux on your computer and use it as an operating system.

For those who just want to play around with Linux or learn more about it, Recalbox can be a fun and easy way to install Linux. It doesn’t offer the same functionality as some of the other solutions on this list, but it is a fun way to experiment with Linux on Windows.

Installing Linux on Windows 10 With WSL (Windows Subsystem for Linux) and Bash

For those who want to get the Linux experience, there are a few solutions that let you install Linux inside Windows. The Windows Subsystem for Linux (WSL) allows you to run a Linux Bash shell on Windows. While it isn’t the same as installing Linux, it does give you the Linux experience.

You can run Linux programs, edit files using a Linux-like command line, and access Linux files from Windows. This can be helpful if you just want to use Linux for certain tasks without having a full Linux installed on your computer.

Conclusion

Installing Linux on Windows can be a challenge, especially if you don’t have administrator access to the computer.

Fortunately, there are a few solutions that allow you to install Linux while still running Windows. These solutions include running Linux in a virtual environment and installing it on a USB drive. Or install it on Windows with WSL or Bash.
