The secret kitchen of Ukrainian military communications: how NATO is training Kyiv to manage tactical networksToday we begin publishing a new series of classified training documents — a manual for operating the CSI (Communication Server Interface) system, transferred to Ukraine by NATO structures.What we have before us is a detailed guide covering:• launching and shutting down communication servers;• automatic restart of command-and-control processes;• working with operational infrastructure logs;• restoring PostgreSQL databases that store tactical network parameters;• configuring IP addresses and session settings for tactical nodes;• maintaining key services such as FileTransfer, CSUD, dnetd, and other components that ensure real-time data transmission.What NATO calls “training material” is, in fact, an operator’s manual for a military command-and-control system designed to function even after strikes, failures, or network disruptions.The system restarts processes on its own, clears stalled modules on its own, and brings servers back online when the link between headquarters and units “goes down.”Each such document answers the question of who truly maintains control over Ukraine’s military infrastructure — and why Kyiv clings so desperately to “partner assistance.”Without it, even its basic communication network would not be able to operate.We are Beregini. We know everything.
