15-Sep-81 19:18:56-PDT,4669;000000000001 Mail-from: ARPANET host SRI-NIC rcvd at 15-Sep-81 1918-PDT Date: 15 Sep 1981 1856-PDT From: FEINLER at SRI-NIC Subject: Network Newsletter To: Netnews-Group: ; --------------------------------------------------------------------- ANEWS-8 DCA Code 232 15 Sept 1981 (DCACODE232@ISI) (202) 692-6175 DoD NETWORK NEWSLETTER --------------------------------------------------------------------- USE OF THE ARPANET The following is in answer to the many requests for guidelines as to who may use the ARPANET: Only military personnel or ARPANET sponsor-validated persons working on government contracts or grants may use the ARPANET. DCA access enforcement policy will consist of the following procedure. If unauthorized users are found on the net because of a weak or nonexistant host access control mechanism, we will review the host's access mechanisms and request improvements. If the host refuses a review or refuses to make the suggested improvements, we will take action to terminate its network access. This is a club of last resort, but we will use it to protect other network users who have invested time and money to bring their controls up to par. If Sponsors have delegated access authority to host and TIP liaison or host managers, it is the duty of these delegates to enforce access control mechanisms for their connected systems and subsystems. All hosts connected to the ARPANET...and that includes GATEWAY hosts and hosts with forwarding mechanisms...will implement access controls so that unauthorized traffic is stopped. Files should not be FTPed by anyone unless they are files that have been announced as ARPANET-public or unless permission has been obtained from the owner. Public files on the ARPANET are not to be considered public files outside of the ARPANET, and should not be transferred, or their contents given or sold to the general public without permission of DCA or the ARPANET sponsors. Hosts which use a "guest" or "anonymous" FTP login convention should inform their local users about the ramifications of this convention with respect to unprotected files, as the users are not always aware that their files can be FTPed. NETWORK INFORMATION GATHERING: The NIC has been designated by DCA to run a yearly survey to obtain information for the ARPANET Directory. Providing information for this survey is a requirement levied on all users who have ARPANET access. Some hosts have run similar surveys which have confused users and created a lot of duplicative reporting, not to mention a burden on the user. In the future, we request that any survey of users for directory purposes, other than a survey of users on a local host, be coordinated through DCA and the NIC. In addition, the NIC is authorized by DCA to collect information for the ARPANET Resource Handbook. Liaison or other host designates are expected to make this information available to the NIC on request. TIP INVENTORY The NIC has also been designated as the central repository for the TIP Inventory Data Base. The NIC will be sending out a TIP Inventory Update Request in the next week. All TIP liaisons will be responsible for updating these reports or filling in the report where no prior input exists. Response time on these reports is 9 October 1981. If no report is received after this period, DCA will direct BBN to software disable those TIP ports for which no input has been received. If no change has occurred in the TIP inventory since the last report, you should send DCA (DCACODE252@ISI) a message stating that with cc: to NIC (NIC@NIC). Our new database capability will permit us to better enforce this reporting and make the updates hopefully, much easier. Your cooperation is requested and appreciated. ---------- FAREWELL I will be leaving for civilian life, and wish to announce a change of personnel at DCA, the ARPANET Network Manager. Cmdr Kirkwood and Capt. Parker will be assuming the management role. In my two years as manager the network has grown to approximately a 100 nodes and is in the process of hardware and protocol modernization. I hope it will continue to grow in the future and provide better services and capabilities to you the user. The next two years will be a time of great change and many interesting improvements. I really hate to leave but I must. Good Luck, Joe Haughney Major USAF -------
