How to use port call waiting to secure an SSH service on Linux

Image
  Port call waiting is a great technique for controlling access to a port by allowing only legitimate users to access the service running on the server. It works in such a way that when the correct connection attempt sequence is established, the firewall will preferably open a closed port. The logic of port knocking is to protect your Linux system from automatic port scanners barking at open ports. In this guide, we will look at how to set up port call waiting and how to configure it to secure your SSH service. For demonstration purposes we use Ubuntu 18.04 . Step 1: Install and configure knockd To get started, log in to your Linux system and install knockd daemon as shown. $ sudo apt install knockd Once installed, open knockd.conf configuration with the desired text editor. Here we use the vim command line text editor. $ sudo vim /etc/knockd.conf The default configuration file is displayed as follows. knockd configuration file   Below [openSSH] section, we need to ch

How to install the latest LXQt desktop in Ubuntu and Fedora

Image
  LXQt developed from popular components LXDE and Razor Qt LXQt is a free, open source, lightweight, and fast desktop environment for Linux and BSD distributions. It has several cool and well-known features borrowed from the LXDE desktop, such as low system resource utilization and sleek and neat interfaces. In addition, one of its distinctive features is the high level of customization to meet desktop usability requirements. The default desktop environment Knoppix, Lubuntu, and a few other lesser-known Linux distributions have had a default desktop environment.

Hot new renders showcase the Samsung Galaxy Watch4 in all its bezel-less glory

Image
  At the moment, it seems that everyone looking to buy a smartwatch is looking forward to the Galaxy Watch4. Samsung wearables have leaked countless times this year, even before the company teamed up with Google to help reinvent Wear OS. With several new leaks, we can get a better look at the Watch4, as well as some of its fitness potential. With new renders courtesy of 91mobiles We take a close look at Samsung’s first Wear OS device in years. In a weird turn of events, it turns out that the renders of the Galaxy Watch Active4 that we saw a couple of days ago actually showcase the Galaxy Watch4. This design seems like a significant departure from the look of the Watch3, ditching the signature rotating bezel to make it look much closer to the Watch Active2. Judging from the images we saw, this could be a rebranding of Samsung’s smartwatch line, with the Watch4 being presented in both classic and active form factors and thus completely abandoning the Active3 model. If this is true, t

Samsung's color choices in new Galaxy Buds2 leaks have a distinct Barney Dinosaur vibe

  True wireless earbuds may have to do with sound first, but the devil, as always, is in the details and they involve aesthetics. More of these details – in particular the expected colors – came from conventional sources. 91mobiles got what appear to be the official close-ups of the buds in black, white and purple, and the cases they will appear in. Notably, the two-tone combination of gloss and matte surfaces of the original Galaxy Buds appears to be missing, while the Galaxy Buds2 has a uniform surface. Recent FCC filings included photographs of the headphones. Another recovered asset appears to be green, which may also appear. All that said, though, availability is likely to be market dependent, so if you’re aiming for purple or green, be prepared to “clean up, clean up everyone, everywhere”. Yes, that’s Barney’s link, it’s here to live up to our headline. Galaxy Buds2 are likely to replace the original Galaxy buds as an entry-level TWE option, so most observers would not

Galaxy F22 isn't a cool fighter, it's just a stupid phone

Image
  The part of my brain that never reached the age of seven knows that two things are cool: fighters and Sonic the Hedgehog. The latter has had a hard time since 1994 but supersonic planes always stay cool. So when I saw the Galaxy F22, I had a fleeting idea that perhaps Samsung had made a tiny fighter jet, or perhaps just a phone styled as a fighter jet. Like there were exhaust stickers around the speakers or something. No, it’s just a dumb phone. It doesn’t have jet engines, it doesn’t fire rockets, it doesn’t even fly, unless you throw it like a flying saucer. And it’s such a shame that you can do just that. SamMobile Records that the Galaxy F22 (UGH) will be more or less identical to the non-5G A22 variant based on a series of regulatory rosters just renamed for the Indian market. This means it will use a 6.4-inch AMOLED screen with 720p @ 90Hz, a MediaTek Helio G80 processor, 4GB of RAM and 64GB of storage with a possible 6GB / 128GB version. It uses a quad rear camera with S

How to install and setup IPTV on Apple TV? 2021

  IPTV is one of the best ways to transmit and broadcast TV programs over the Internet using the TCP/IP protocol suite. When compared to traditional streaming services, IPTV offers more unique dynamic features to enhance user experience. IPTV is usually provided by the service provider, and it offers all kinds of live TV programs and video-on-demand content to its users. Here broadband connection acts as a means of data transmission and is an effective means of transmission while comparing with previous transmission modes. Running  IPTV  is not the same as traditional TV broadcasting as it only offers one program at a time. While changing channels,  a  new  broadcast  from the provider’s server will be made available to viewers directly. You can easily install IPTV on Apple TV, iOS, iPhone, iPad and macOS as well. IPTV uses IP multicasting along with Internet Group Management Protocol (IGMP) to broadcast live TV programming and uses Real-time Broadcasting Protocol (RTSP) to broadca
