How to Install Google Chrome on Debian

Posted by Kiran.BL on Wednesday, August 21, 2019 in

Google Chrome is one of the most popular web browsers among users. The most common default web browser of a Linux operating system is Firefox. But most of them use Google Chrome because of its user-friendliness and its features.

In this article, let us discuss on how you can install Google Chrome on Debian.

Note: Google Chrome is not available on Debian's repository. We need to download Chrome from Google's repository.


Download Google Chrome:

-> Launch Terminal
-> Update and upgrade the system repositories by running:

# apt update

# apt upgrade

-> We can get Google Chrome from its official repository using the wget command:




Note: By default wget tool will not be installed in the system to and you will get an error like you see the below screenshot.



The GNU Wget is a free and open source tool for non-interactive download of files from the Web. It supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies and much more.

To get the wget tool to your system please follow the following command:

# sudo apt-get install wget

Or # sudo apt install wget


Once you make sure that you have wget tool installed in your system, then use the command to download Google Chrome from its official repository




Install Google Chrome on Debian:

To install Google Chrome alongside all the dependencies, run the command:

# sudo apt install ./google-chrome-stable_current_amd64.deb




Once installed, you can launch it by clicking on Activities > Google Chrome.

You can also launch from your terminal using the command:

# google-chrome

When launching Chrome for the first time, you will get a pop-up notification as shown in the below.




Choose according to your preference and click the OK button.

This will open Google Chrome's browser default page.


Removing Google Chrome

If you are not happy with this browser, you'd rather use another browser instead.

Uninstall Google Chrome using the command

# sudo apt purge google-chrome-stable

Next, run

# sudo apt autoremove

The second command clears away any residual packages and helps free space.

Conclusion

Give it a try and give us your experience. If you like this post, please like and share this post. Thank you for your time.

How to set the root password

Posted by Kiran.BL on Sunday, July 21, 2019 in










Debian is the oldest Linux distribution. Debian is one of the most popular Linux distributions. As of 2018, DistroWatch lists 141 active Debian derivatives using Debian codebase. The most popular ones are Ubuntu, Linux Mint Debian project, Knoppix, Deepin and so on.

 When we install a fresh copy of this operating system, the root password is not set by default. So, in this article, we will be discussing how to set the root password.

Note:

1. Directly logging in as root is like playing with fire. Because one little typo is enough to lose critical data or make your system unbootable.

2. Note that desktop environments will function differently if you log in to them as root.

 3.This article holds good for Debian and Debian based Linux distributions

To set a root password, run the following command:

$ sudo passwd

Type in the password for your logged in user and press <Enter> to continue.







Now type in your desired root password and press <Enter>.



Retype the root password and press <Enter>.






The following message will appear:

 passwd: password updated successfully






You have successfully set your password. Now you can log in as root using your root password.

 If the above message showed up on your terminal, then you can now use the root privileges by typing:

 su

And then type the password you have chosen. That's it!

Else, start over the steps of the answer, you probably typed something wrong.

If you wish to change the root password, all you need to do is to run the command again:

 $ sudo passwd

Now do the same things as discussed in this article.

 If you have any questions about it please do not hesitate to comment below.

Enable desktop icons and right click on Elementary OS

Posted by Kiran.BL on Friday, January 26, 2018 in


Elementary is an elegant operating system. It resembles like a Mac operating system. When you install Elementary OS afresh, you will not see icons on the desktop. If we right-click on the desktop, you will not get the right-click menu as in other operating systems. 
This guide will help you to enable desktop icons and desktop right-click in Elementary OS. 
Step 1. Install Nautilus dconf-tools:
Open terminal and type the following command.
sudo apt update.
sudo apt install --no-install-recommends nautilus dconf-tools.

Step 2. Choose what you want to view on your Desktop:
Run dconf editor from Slingshot.

Go to Org -> gnome -> nautilus -> desktop in the left menu tree, check the necessary parts.

Step 3. Edit:
Go to Org -> pantheon -> desktop -> Cerbere and add as shown below.
 Edit the 'Monitored-process' as ['wingpanel', 'plank', 'slingshot-launcher --silent', 'nautilus -n']

Step 4. Config Again:
 Go back to Org -> gnome -> desktop -> background and check the box next to "show-desktop-icons" in the right menu. 

Step 5. Run Command:
 Open terminal and type following command 'nautilus -n'.

You will see that there are icons on the screen and the right-click menu also works.
To add an icon, click "Applications" in the upper left corner and drag it to the desktop.

Note: If there any problem, you can log out and log in again to see the changes. You can also reboot the system.
                                                                                OR

You can install "Desktop folder" from the Github page or Appcenter and restart your computer.

 Github link: https://github.com/spheras/desktopfolder
Appcenter link: https://appcenter.elementary.io/com.github.spheras.desktopfolder 

 This application will enable your desktop and right click functions

Posted by Kiran.BL on Sunday, November 19, 2017 in

Wireshark

Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions.

Features (as listed on the website)

Wireshark has a rich feature set which includes the following:

  •     Deep inspection of hundreds of protocols, with more being added all the time
  •     Live capture and offline analysis
  •     Standard three-pane packet browser
  •     Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others
  •     Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
  •     The most powerful display filters in the industry
  •     Rich VoIP analysis
  •     Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
  •     Capture files compressed with gzip can be decompressed on the fly
  •     Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform)
  •     Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
  •     Coloring rules can be applied to the packet list for quick, intuitive analysis
  •     Output can be exported to XML, PostScript®, CSV, or plain text
