ARCTAN Users/Operators Manual.

The Acoustic Research Center Terminal at NRL ARCTAN was established by DARPA to provide ARPA personnel and contractors the capability of acessing the Acoustic Research Center ARC at Moffett Field, California from the Washington, D.C. area. The ARCTAN facility permits local users at the Naval Research Laboratory NRL to access the ARC via a secure subnet of the ARPANET. During such times, the ARCTAN is a serveruser host on the classified subnet of the ARPANET. This report describes the ARCTAN system and its use. The first section gives an overview of the ARCTAN facility. The second section describes the procedures required by a user to access the ARC and use the capabilities of the ARCTAN terminal. The third section describes the procedures to be followed by an operator to put the ARCTAN on the ARPANET as a secure host and to remove it from the net.
