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...

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...

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...

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...

Managed Extended Detection and Response (MXDR) has become one of the most sought-after security services in the enterprise market — and with good reason. It promises the holy grail: broad visibility across endpoints, network, cloud, email, and identity, combined with the 24/7 human expertise most organizations simply cannot build in-house. . However, the rapid growth of the market has produced a wide range of providers whose capabilities vary considerably beneath the surface. Choosing the...

Implementing IPsec Tunnels for Secure Network Communication

I started this project because I was using a number of IPIP tunnels to connect a number of private networks over the Internet, and I needed encryption for a few resons.

I started this project because I was using a number of IPIP tunnels to connect a number of private networks over the Internet, and I needed encryption for a few resons. Above all I wanted to be able to use standard protocols such as FTP and NFS without having to worry about cleartext passwords and snooping. I knew that I needed IPsec, and the only free implementation under active development I could find for Linux was FreeSWAN, but looking closer it seemed too much for my simple case. My first impression was that it was hard to understand and hard to configure, especially for the simple case of manually configured tunnels with fixed keys. Routing was also strange. I wanted something resembling the standard IPIP tunnel, but when I could not find it, I printed out the IPsec RFCs and started reading, and after that I started coding. I decided to use the cryptoapi patches for the encryption/decryption algorithms, which really gave me a head start on the hard stuff. The code has been running on my netword for some time now, and I feel that it's time to share the code to the rest of the community. Please try it out and let me know what you think!
