One of the fundamental requirements of the Kubernetes networking model is that each pod must have its own IP address, and any other […]
IT environments are becoming increasingly complex. In these conditions, having up-to-date information about the nodes present in the network and subject to processing is critically important for IT automation systems. In Red Hat Ansible Automation Platform, this issue is addressed through so-called inventories — lists of managed nodes. In its simplest form, an inventory is a static file. This is the ideal […]
Today, several major DNS services and DNS server manufacturers will hold a joint event, DNS flag day 2020, aimed at focusing attention on resolving issues with IP fragmentation when processing large DNS messages. This is the second such event; last year's 'DNS flag day' concentrated on the correct handling of EDNS requests. Participants in the DNS flag day 2020 initiative urge to establish recommended buffer sizes […]
GitHub has announced the availability of Code scanning for all users, a feature that was previously offered only to participants in a limited testing program for new experimental capabilities. The service scans every 'git push' operation for potential vulnerabilities. The results are attached directly to the pull request. The checks are performed using the CodeQL engine, which analyzes patterns with typical examples of vulnerable code (CodeQL allows creating a pattern for vulnerable […]
