Documentation Improvement and AI

By Rainer GerhardsPosted on Posted in News, rsyslog documentation

For a long time, I struggled with the daunting task of enhancing the documentation for Rsyslog. My extensive knowledge of Rsyslog technology often made it challenging for me to create user-friendly documentation, especially for individuals with little to no syslog background. Additionally, as a non-native English speaker, I was aware that some of my sentences might be harder to understand than desired. But thanks to the breakthroughs in generative artificial intelligence (AI), the game has changed, and a new era of documentation improvement has begun.

Elevating Syslog Security: RSyslog Introduces DTLS Plugins for UDP

By Rainer GerhardsPosted on Posted in News

We at the RSyslog project are excited to share our recent advancements in syslog security. We have introduced initial plugins for Datagram Transport Layer Security (DTLS) syslog, namely imdtls (input module) and omdtls (output module). This development, which aligns with RFC 6012, represents a significant enhancement, albeit not a game-changer, in our continuous efforts to improve secure log transmission.
