  • Network Security Rocky Linux/Centos/RHEL 8 - Unixcop

    Hardening network security devices minimize the risk of unauthorized access into a network’s infrastructure. Vulnerabilities in device management and configurations exploit weaknesses for a malicious cyber actor to exploit in order to gain presence and maintain persistence within a network.

    In addition to, Hackers have shifted their focus from exclusively exploiting traditional endpoints to increasingly exploiting specialized and devices, including routers and switches. They do this through common weaknesses in configurations, specific routing protocols, and implanting malware in the OS.

    So Ensure that all network security configurations are correct. Including static IP address assignments, DNS, WINS, whether or not to register a specific interface, binding order, and disabling settings on DMZ, 00B management, or backup networks. Also, check CSF configuration.

  • How to see grep output in color with highlighting feature

    The grep command is the de facto tool for searching text files. However, when there are too many matches, finding the requested text in the search results can be difficult. So grep comes with --color='auto' option. It surrounds the matching string with the colour, thus resulting in enhanced output.Now you know grep can color-highlighting the matched text or words in its output. However, by default, that option is turned off. So let us see how to colorized grep by default for viewing the entire file with highlighted matches on Linux or Unix-like systems.

  • Linux Fu: User Space File Systems — Now For Windows, Too! | Hackaday [Ed: Better just use the real thing -- without NSA back doors and recurring data losses]

    One of the nice things about the Unix philosophy that Linux inherited is that the filesystem is very modular. That’s good, too, because a typical system might want a choice of filesystems like ext4, reiserfs, btrfs, and even network systems like nfs. Besides that, there are fake file systems like /sys and /dev that help Linux make everything look like a file. The downside is that building a filesystem required changing the kernel or, at least, writing a loadable module. That’s not as hard as it sounds, but it is a little more difficult than writing a normal program. Then came FUSE — file system in user space. This is a single file system module that allows you to create new file systems by writing ordinary code.

  • Yet another gremlin: the zero-width space

    The gremlin detector script in A Data Cleaner's Cookbook now looks for zero width spaces (U+200B, hex e2 80 8b, ​).

    Like a soft hyphen (SHY), a zero-width space (ZWSP) is usually non-printing and invisible, and indicates for a Web browser or word-processing program where a string of visible characters can be broken when wrapping a line. With SHY, the program will add a hyphen at the end of the wrapped line, while a ZWSP just means "You can break the string here when wrapping".

    Also like a SHY (and a no-break space (NBSP)), a ZWSP can cause problems where it isn't needed. A quick googling for "problem with zero width space" turned up ZWSP-caused issues with

Jam: The time for Open-source Clubhouse and Twitter Spaces Alternative

Filed under
Software

For someone who witnessed the old golden days of PalTalk, Clubhouse is a modern version of PalTalk with social networking characteristics rather than chat and messaging channels.

In different words, it is a social network which focuses on real-time voice conversations for groups. Although, it was first lunched for iOS users and with invites, many users could not join unless with workaround, it gained popularity among the new generation, especially for discussing politics.

But what about if a certain community wants to setup its own voice-based private social network? Here, the decision makers will face a problem with limited options: the idea is rather new and open-source developers need time to create the alternatives.

Which is better; Ubuntu or Debian

Filed under
Debian
Ubuntu

Linux is a widely used open-source operating system; it manages the connection between applications/programs and hardware like other Operating Systems. Applications make the requests, and operating systems map those requests to the hardware components. Linux operating systems have hundreds of distributions (distros); a Linux distribution is also an operating system made using Software collections based on Linux Kernel. The well-known distros of Linux OS include Debian, Ubuntu, Linux Mint, Fedora, MX Linux, Deepin, etc. The notable information is that Debian is a Linux-based distribution, and Ubuntu is a distribution based on Debian. Ubuntu and Debian are almost similar, but they have few differences, such as Ubuntu is inclined towards user-friendliness and Debian is more concerned with software freedom. In this piece of writing, we will present the difference between two distros, Ubuntu and Debian, and analyze which Linux distribution is better.

Debian

Debian is an old but very stable Linux distro: the initial version of Debian was released in 1993. In 1993, software engineer Ian Murdock issued an open invitation to various developers to develop a relatively new operating system based on the Linux kernel. This invitation was called the Debian Project; therefore, the development phenomenon of Debian is known as the Debian Project that includes hundreds of developers who contribute towards the development of Debian. Moreover, its features and stability forced the developers to consider it a benchmark for a few other Linux distributions such as Ubuntu, Linux Mint. It is noted that more than 100 distributions of Linux are derived from Debian. It is developed by hundreds of developers that form the Debian project.

Ubuntu

Ubuntu is marked as the most popular Linux distro and was firstly released in the year 2004. Ubuntu is designed for computers, smartphones, and network servers, and it is used globally, such as in offices, homes, programming, IoT devices, TV OS, etc. It releases twice (April and October) a year with a gap of 6months. The exciting thing about Ubuntu is that it is based on the Debian distro of Linux: this relationship between Ubuntu and Debian makes them similar in many features and functionality.

Rspamd 3.0 Spam Filtering System Released with Reworked HTML Parser

Filed under
Software
Security

Rspamd 3.0 has been released as the newest version of this leading open-source spam filtering software and it’s coming with plenty of changes.

Rspamd is an advanced high-performance spam scan software for Linux and Unix servers which delivers very accurate filter results. It is fast, open source, and designed to process hundreds of messages per second simultaneously.

Rspamd 3.0 can work with the most popular mail transfer systems, such as Postfix, Exim, or Sendmail. Each message is analyzed by Rspamd and given a spam score. The higher the score – the more likely the email should be considered unsolicited.

Compared to SpamAssassin, Rspamd is more actively maintained. Because it is written in C, Rspamd is much faster than Spamassassin which is written in Perl. Rspamd has a number of features that allow it to filter email on average 10 times faster than SpamAssassin, as well as provide better quality filtering. On top on that, Rspamd comes with a DKIM signing module so you will not have to use another software to sign your outgoing emails.

Astro Pi 2: New Raspberry Pi hardware with updated camera, sensors to head to the ISS this year

Good news for earthbound Pi-tinkerers hoping to get their code into orbit: a follow-up to 2015's Astro Pi is due to head to the International Space Station (ISS) this year. Time has moved on a bit since the Principia mission of Tim Peake where the first units were installed aboard the orbiting outpost. While over 54,000 participants from 26 countries have since had code run on the hardware, the kit has fallen somewhat behind what is available on Earth. To that end, some new units are due to be launched, replete with updated hardware. In this case, heading to orbit will be Raspberry Pi 4 Model B units with 8GB RAM, the Raspberry Pi High Quality Camera (a 12.3MP device) and the usual complement of gyroscope, accelerometer, magnetometer, humidity, temperature and pressure sensors for users to code against.
