man7.org Overview

Description of man7.org

man7.org appears to be the personal and professional website of Michael Kerrisk, a well-known Linux author and trainer. Based on the page title, navigation, and visible content, the site provides access to Linux programming training courses, conference presentations, articles, a blog, and online manual pages related to Unix/Linux systems programming.

The homepage also references The Linux Programming Interface and the man-pages project, suggesting the site serves as an educational and technical resource for developers, system programmers, and students. Its classification across multiple web-categorization sources as information technology and education is consistent with the content shown in the scan.

Safety Assessment for man7.org

The available scan data is strongly reassuring. At the time of this scan, 0 out of 91 security engines flagged the domain, the malware scan reported 0 flagged files out of 52 checked, and major threat-database checks did not indicate phishing, malware, or blacklist listings. The domain is also long-established, with an age of about 20 years, and it has a meaningful traffic presence based on its Tranco ranking.

The only minor caution in the scan is that a few referenced external domains were marked by a malware scanner, but these appear to be third-party links embedded or cited by the site rather than malicious files hosted on man7.org itself. In addition, the malware scan output included generic heuristic labels, which are lower-confidence signals when not supported by broader detection consensus. Based on available data, no threats were detected at the time of this scan.

Technical Description

The site uses a valid Let's Encrypt SSL/TLS certificate with an expiry in September 2026. It is hosted on IP address 45.84.74.9 in Munich, Germany, with Apache/2.4.58 running on Ubuntu, and the registrar is Gandi SAS. The domain has been registered since 2005 and is configured with Gandi nameservers.

DNSSEC appears to be unsigned, which is not uncommon but means DNS responses do not benefit from DNSSEC validation. No major technical security concerns are evident from the provided scan data beyond that minor hardening observation.
