Design, deployment, migration and troubleshooting of Usenet infrastructure based on INN and standard NNTP workflows, from public reader systems to transit, peering and long-term archival environments.
Usenet infrastructure has very different requirements depending on whether a server is serving readers, moving articles between peers, or preserving large historical collections. The architecture should reflect those roles instead of forcing everything into one spool and one policy.
I can help with INN configuration, feed topology, storage, filtering, overview, retention, migrations and the operational details required to keep an NNTP service predictable over time.
Separate roles and policies according to how the server is expected to receive, store and serve articles.
Configure peer relationships, feed patterns, routing and acceptance policy around the traffic a server should carry.
Deploy and tune Cleanfeed-NG, Postfilter-NG and related policy so unwanted traffic is controlled without hiding operational problems.
Recover and normalize old article collections, deduplicate them and import them safely into modern INN storage.
The work is based on operating real NNTP systems rather than treating Usenet as an abstract protocol. That includes throughput, retention, filtering behavior, peer relationships, old article formats and failure recovery.
Software projects such as Cleanfeed-NG, Postfilter-NG and NNTPSwitch grow out of the same operational requirements and can be integrated where appropriate.
Whether you are deploying a new INN server, migrating an existing installation, arranging peering or importing historical material, start with a description of the current environment and the goal.
