system security Linux network The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Server Securityopen-source Linux administration
open-source Linux administration Cron has existed in Unix and Linux environments for decades, handling backups, cleanup scripts, patching jobs, log rotation, monitoring tasks, and other maintenance work that administrators do not want to run manually. Most Linux servers rely on it constantly, which is exactly why attackers continue abusing it for persistence after a system has already been compromised. . Persistence through cron is not complicated. Attackers do not need a rootkit or advanced malware framework to maintain...

security breach linux A major internal repository breach at GitHub has exposed a critical and overlooked blind spot in Linux supply chain security. Kernel exploits, exposed SSH services, weak firewall rules, and vulnerable daemons dominated the Linux threat model for years, and in many environments, they still matter. But recent supply-chain incidents involving GitHub ecosystems, npm packages, and malicious developer tooling point somewhere else entirely: the developer workstation. . The breach matters because...

Security Trends access control multi-tenant
access control multi-tenant Linux administrators often face an ugly choice in the cloud: prioritize convenience and cost-efficiency by sharing infrastructure, or sacrifice those benefits for the sake of total isolation. Most modern Linux workloads don't live on their own private servers anymore. They live in shared environments like Kubernetes clusters, where multiple teams and services run side-by-side. It sounds efficient, and it usually is. . But cloud isolation isn't as ironclad as it looks on the diagram. If you...

ftp serverproftpdfile transferComparing the Differences Between Vsftpd and ProFTPd FTP Servers
FTP is a standard protocol that is used to transfer files widely, and FTP servers like Vsftpd and ProFTPd provide a way to use that protocol and access plus transfer files stored on a remote server. Here we quickly learn the difference between Vsftpd and ProFTPd. . vsftpd (Very Secure FTP Daemon) is a GPL-licensed FTP server software developed to provide a secure but fast way to transfer files. It is popular among Linux users because of its simplicity and efficient use of system resources. That’s the reason why most Linux distros such as Redhat, Fedora, Ubuntu, Debian, and more offer this FTP server package to install directly from the base repository of the system. Learn – How to install VSFTPD to Setup FTP Server on Ubuntu 22.04. ProFTPd (Pro FTP daemon) is also an open-source FTP server just like Vsftpd but comes highly customizable and extensible. It offers a wide range of advanced features like virtual hosts, SSL/TLS encryption, and LDAP authentication. It is designed to be a highly feature-rich FTP server. .

encryptionopen sourcefile transferCroc: Secure File Transfers With Encryption Across Platforms
croc is a free and open-source command line tool for secure file transfers between computers. It uses relay-assisted peer-to-peer transactions and end-to-end encryption via password-authenticated key exchange. The program is written in Go and is available for Linux, Windows, macOS and *BSD. Learn about croc's key features and see how easy it is to use croc to send a file or folder in this Linux Uprising tutorial. . The idea behind croc is being able to transfer files and folders between cross-platform computers securely, fast and easy. With support for resumable, peer-to-peer transfers. As a bonus feature, croc is also able to securely transfer a short text or URL directly. The data transfer is done using a relay, either using raw TCP sockets or websockets. When the sender and the receiver are on the same LAN, croc uses a local relay, otherwise a public relay is used. Thanks to this, croc can send files between computers in the same LAN, or over the Internet, without having port-forwarding enabled. The data going through the relay is encrypted using a PAKE -generated session key. For this, croc uses code phrases, a combination of three random words. By default, a code phrase can only be used once between two parties, so an attacker would have a chance of less than 1 in 4 billion to guess the code phrase correctly to steal the data. . Explore croc, a powerful command-line tool crafted for secure and efficient file transfers across multiple platforms, featuring advanced encryption for superior data safety.

file transferSSHSFTPHow To Securely Transfer Files Using SFTP And SCP Over SSH
File Transfer Protocol (FTP) was once the most widely used protocol for transferring files between computers. However, because FTP sends authentication information and file contents over the wire unencrypted, it's not a secure way to communicate. Secure Copy (SCP) and the more robust SSH File Transfer Protocol (SFTP) address this security concern by providing data transfer over a fully encrypted channel. You can use these alternatives for transferring files securely over the Internet or any other untrusted network. . Both SCP and SFTP rely on Secure Shell (SSH) as their underlying protocol. SSH establishes a secure and encrypted channel of communication between computers using authentication and encryption based on Public Key Infrastructure. SSH uses encryption for the authentication data exchanged to set up the session and the subsequent data transfer. The link for this article located at Linux.com is no longer available. .

I recently ran into the problem of not having enough hard drive space on my slackware linux laptop, but was lucky enough to have a much bigger drive sitting around from before and wanted a way to perform a hassle free seamless upgrade. i had this idea and it worked pretty well so i thought i would share it since i think it's pretty cool and only requires the use of two tools that should be included with all distributions. sometimes you won't find netcat (known as nc, or ncat as it is sometimes named) and if bash incorporated my server redirections patch that i posted before you wouldn't need it at all, but for now it's required to listen for the incoming connections over the net. .

We've covered SSH before in CLI Magic, but this week let's look at some additional SSH features that new users might not be aware of. For the purpose of this article, we'll be looking specifically at OpenSSH, but many of these features apply to other SSH variants as well. SSH is the best way to establish a secure connection to a remote networked machine. Whether you want to transfer files, encrypt traffic, or just log in to a remote machine, SSH is the way to go. . Let's start with one of the basics. If you log into a remote machine frequently, you might be tired of typing your password over and over again. You can set up SSH so that you can authenticate without typing a password. First, you'll need to create an authentication key for SSH. This will actually consist of a key pair: a private key and a public key. To create your keys, run the command: ssh-keygen -t dsa The link for this article located at Linux.com is no longer available. .
