  • How to get Battery status notification when a battery is full or low

    Linux laptops are good for Nix users, but it often drains the battery.

    I tried many Linux operating systems, but did not have a long battery life like Windows.

    Charging a battery for a longer duration will damage your battery, so unplug the power cable when it is 100% charged.

    There is no default application to notify when the battery charged or discharged, and you need to install a third-party application to notify you.

    For this, I usually install the Battery Monitor app, but it was deprecated, so I created a shell script to get the notification.

    Laptop battery charging and discharging status can be identified using the following two commands.

  • 5 advanced rsync tips for Linux sysadmins | Enable Sysadmin

    In a previous article entitled Sysadmin tools: Using rsync to manage backup, restore, and file synchronization, I discussed cp and sftp, and looked at the basics of rsync for moving files around. There are also a couple of other great articles here on Enable Sysadmin on tar and SSH you should take a look at. Copying files to and from remote systems and having an easy way to run a backup of something you're working on (or, for that matter, critical company data) are basic, useful tools in the sysadmin toolbox that I use again and again. Sometimes, however, you may want to do something a little more sophisticated, like move data across a less trusted or slower link. Rsync can provide encryption to protect it in transit, compression to make it flow better, and checksums to ensure you get what you were expecting.

  • How to Create a file in Ubuntu Linux using command & GUI - Linux Shout

  • How to install Virtualmin on Ubuntu 20.04 for a cPanel/CentOS-like web hosting control panel - TechRepublic

    For many, Red Hat pulling support from the standard CentOS releases had some serious side effects. One of the biggest dominoes to fall was cPanel--for many web hosting companies, cPanel is the de facto standard control panel. It offers absolutely everything necessary to manage the hosting of your every client's needs.

    Once Red Hat pulled the plug on CentOS 8, cPanel announced they wouldn't be supporting CentOS Stream. The good news is that the company is accelerating their efforts to support Ubuntu Server LTS, and should have that ready to ship by late 2021.

    For those looking to either migrate away from CentOS or are looking for something that can be used on the Ubuntu platform for now (or for good), there's always Virtualmin.

  • New coalition aims to combat growing wave of ransomware attacks [iophk: Windows TCO]

    The California-based nonprofit aims to produce recommendations that will help governments and the private sector tackle the scourge of ransomware attacks.

    [Attackers] have increasingly used these types of attacks -- which involve accessing and encrypting the victim’s network and demanding payment to allow access again -- to hit major targets, with city governments in Atlanta, Baltimore and New Orleans severely impaired by ransomware attacks over the past two years.

    More recently, hospitals have become a target during the COVID-19 pandemic, with cyber criminals seeing vulnerable hospitals as easy targets more likely to pay a quick ransom as health care systems struggle to keep up with coronavirus cases. In some instances, the cyberattacks have been blamed for deaths due to delayed care.

  • This tiny shortcut can completely crash your Windows 10 device

    A zero-day exploit has been discovered that can crash your Windows 10 device – and, even more worrying, can be delivered inside a seemingly harmless shortcut file. The vulnerability can corrupt any NTFS-formatted hard drive and even be exploited by standard and low privilege user accounts.

    Security researcher Jonas Lykkegaard referenced the vulnerability on Twitter last week and had previously drawn attention to the issue on two previous occasions last year. Despite this, the NTFS vulnerability remains unpatched.

    There are various ways to trigger the vulnerability that involve trying to access the $i30 NTFS attribute on a folder in a particular way. One such exploit involves the creation of a Windows shortcut file that has its icon location set to C:\:$i30:$bitmap. Bleeping Computer found that this triggered the vulnerability even if users did not attempt to click on the file in question. Windows Explorer’s attempts to access the icon path in the background would be enough to corrupt the NTFS hard drive.

  • This Easily-Exploitable Windows 10 NTFS Bug Can Instantly Corrupt Your Hard Drives

    Jonas says that this Windows 10 bug isn't new and has been around since the release of Windows 10 April 2018 Update, and remains exploitable on the latest versions, as well. BleepingComputer shared that the problematic command includes $i30 string, a Windows NTFS Index Attribute associated with directories.

    [...]

    After running the command, Windows 10 will start displaying prompts to restart the device and repair the corrupted drive. Apparently, the issue also impacts some Windows XP versions and similar NTFS bugs have been known for years but are yet to be addressed by the Windows maker.
