********************************************************************** DDN MGT Bulletin 76 DCA DDN Defense Communications System 24 Aug 90 Published by: DDN Network Info Center (NIC@NIC.DDN.MIL) (800) 235-3155 DEFENSE DATA NETWORK MANAGEMENT BULLETIN The DDN MANAGEMENT BULLETIN is distributed online by the DDN Network Information Center under DCA contract as a means of communicating official policy, procedures and other information of concern to management personnel at DDN facilities. Back issues may be read through the TACNEWS server ("@n" command at the TAC) or may be obtained by FTP (or Kermit) from the NIC.DDN.MIL host [192.67.67.20] using login="anonymous" and password="guest". The pathname for bulletins is DDN-NEWS:DDN-MGT-BULLETIN-nn.TXT (where "nn" is the bulletin number). ********************************************************************** TAC User Registration Clarification DDN instituted Usage Sensitive Billing (USB) in October 1989 as a more equitable method of cost recovery than the prior flat rate billing method. Under USB, TAC user traffic and connection time are charged to the authorizing host. In order to ensure complete and accurate billing of these users, controls on user registration were instituted. It has always been the policy that only adminstrators of hosts directly connected to the MILNET could authorize TAC access for their users. This bulletin is issued as clarification for those host administrators of hosts that are changing their connection pathways to the MILNET. Thus, you as a host administrator can only authorize users for TAC access if your host remains directly connected to the MILNET. If your host is moved behind a concentrator or gateway, you will no longer be able to authorize users for TAC access. In addition, you will need to transfer your jurisdiction over existing users to a host administrator associated with a directly connected MILNET host. If you have questions about TAC user registration, please send a message to REGISTRAR@NIC.DDN.MIL or call 1-800-235-3155.
