Pathworks for DOS DECnet Network Management Guide V4.1 Sep91

This document is the "PATHWORKS for DOS DECnet Network Management Guide", published in September 1991 for PATHWORKS for DOS Version 4.1.

The guide primarily focuses on detailing the DECnet Network Control Program (NCP), explaining how users can utilize NCP commands to:

1. Set up a personal computer as a node on a DECnet network, including defining its name, address, and access control information.
2. Manage and configure various network parameters, such as line states, buffer sizes, and maximum logical links.
3. Monitor the network by displaying detailed information about the local node and other nodes, including real-time counters for network activity and event logs for troubleshooting.
4. Perform diagnostics and testing using loopback commands to verify the operation of network components, from local node software to physical connections and remote nodes via a loopback mirror.

The guide also describes the underlying permanent and volatile databases (e.g., DECPARM.DAT, DECNODE.DAT, DECALIAS.DAT) that store network configuration and operational data, and introduces network management servers like the Network Management Listener (NML) and the Maintenance Operations Protocol (MOP) for device loading and dumping.

In essence, it's a technical manual for network administrators and users responsible for configuring, maintaining, and troubleshooting DECnet networks on DOS-based personal computers during the early 1990s.
