IAB/IETF NOW PART OF ISOC Meeting in Kobe, Japan, on June 15, 1992, the Board of Trustees of the Internet Society voted to accept a recommendation from the Internet Activities Board to bring the IAB and all of its activities into the Internet Society, with the IAB serving as a technical advisory group of the ISOC. The IETF will continue to pursue standards-setting and other engineering activities under this new umbrella, and the IRTF will continue to pursue research questions of importance to the Internet. The IAB was renamed the Internet Architecture Board. B. NEW POLICY ON POSTSCRIPT FOR STANDARDS DOCUMENTS Since 1989, the Internet policy set by the IAB has allowed Postscript RFC's but required that parallel ASCII versions exist as well. The ASCII versions of Postscript have been allowed to be substandard, e.g., missing diagrams and not meeting the customary standards on format. Experience has shown that that the results have been less than satisfactory, and the IAB is now amending the policy in the following manner: RFCs that document standards-track specifications MUST have their reference text in ASCII. That is, the ASCII version of standards-track specifications must be complete and properly formatted. A secondary version in Postscript is still allowed, but its Status of Memo will note that it is not primary. No policy can be universal. If the drafters of a standards specification RFC feel they have a legitimate need for using Postscript for the reference version of a specification, they should discuss this with the IESG, preferably early in the process. Exceptions will not be granted lightly, but nothing is impossible. This policy change affects only standards-track specifications; other RFC's will continue to follow the former rules. HISTORY AND BACKGROUND In 1989, there was a raging discussion on the question of Postscript RFCs, both on public mailing lists and within the IAB. Based upon the public discussion, the IAB at its July 1989 meeting agreed upon a dual-version policy. This was reflected in the Instructions for RFC Authors and announced in the IAB REPORT Cooper [Page 3] Internet Monthly Report June 1992 [Internet Monthly Report, October 1989]: "The IAB has noted the intense concern in the community about Postscript-only RFC's; unfortunately, there is no ideal solution for this problem. Until ODA or its equivalent is widely available, some combination of ASCII and Postscript is the best we can do. The IAB has instructed the RFC Editor to obtain an ASCII version from the author of any Postscript-only document whenever possible, and both versions are to be made publically available. Although the dual versions may cause significant extra work for both authors and editor, this appears to be the only feasible compromise." In the succeeding three years, the situation has not improved. ODA has not saved us, and the drawbacks of Postscript noted in July 1989: 1) printing capability is not universal 2) difficult to cut and paste 3) difficult to search 4) file sizes are too large 5) unable to view from a terminal are unchanged. Typically, we have found that the ASCII versions of Postscript specifications have been derived mechanically, with minimal or no editorial effort. The result has been unreadability at best and at worst typographic errors in specifications where precision is required and expected. What has changed in three years is the economic significance of the Internet standards process. As a result, the Internet community in general and the IAB in particular have lavished a great deal of time and effort to improve the quality of our standards process while attempting to preserve its manifest virtues. There is no question in anyone's mind that Postscript documents are prettier and perhaps easier to read than corresponding ASCII documents. However, we believe that other issues are paramount for the formal specification of protocols and procedures. In particular, a reference specification must be universally printable, and it must be possible to cut-and-paste machine- processable program fragments from the text. It should be possible to easily search for desired text. When fancy explanatory diagrams are desired, it may be appropriate to create two documents, an introductory document in Postscript and the formal specification in ASCII. We have a great deal of experience with using ASCII to effectively document Internet Cooper [Page 4] Internet Monthly Report June 1992 protocols and procedures, and we believe that a carefully written ASCII document can convey the desired information clearly and precisely. It may be hoped that the restriction to a single font will encourage authors to make every word count. This policy was proposed to the IETF on May 28, 1992, and was very extensively discussed on the IETF mailing list. The great majority of comments received by the IAB were strongly in favor of this change. Therefore, it was formally adopted by the IAB at its Kobe meeting. C.

Deborah Estrin (Estrin@USC.EDU) END-TO-END SERVICES ------------------- No progress to report this month. Bob Braden (Braden@ISI.EDU) RESOURCE DISCOVERY AND DIRECTORY SERVICE ---------------------------------------- Several members of the research group have been discussing conceptual and implementation relationships between Internet resource discovery systems, towards the goal of supporting seamless interoperation of resource discovery using multiple underlying systems. To help analyze the problem, we are developing a taxonomy with dimensions concerning resource granularity, distribution, interconnection topology, and data integration mechanism. This taxonomy provides inferences about the ability of a system to support organizing, browsing, and searching operations, and about what is needed to provide gateways between individual systems. Mike Schwartz schwartz@cs.colorado.edu Cooper [Page 7] Internet Monthly Report June 1992 INTERNET ENGINEERING REPORTS ---------------------------- 1. The Fall IETF is scheduled for November 16-20, 1992 in Washington, DC. Our local host is U.S. Sprint. The Spring 1993 IETF will be held in Columbus, Ohio, March 28th - April 2nd, hosted by OARnet and The Ohio State University. 2. The IESG received one request to consider the following Internet Draft as a standards track item: a. "BGP OSPF Interaction" be published as a Proposed Standard. Additionally, the IESG is considering RFC 1144 "Compressing TCP/IP headers for low-speed serial links" for Draft Standard status. RFC 1144 was published as a Proposed Standard in December 1990. Last Call notifications were sent to the IETF list on both items. 3. The IESG made the following recommendations to the IAB during the month of June 1992: a. RFC0734 (SUPDUP), RFC0913 (Simple File Transfer Protocol), RFC0953 (Hostname Server), and RFC1037 (NFILE - a file access protocol) be moved to Historical Standard status. b. RFC1139 (Echo function for ISO 8473) remain a Proposed Standard c. RFC783 (THE TFTP PROTOCOL-REVISION 2) as documented/updated in , be published as an Internet Standard. d.

Test conferences were run almost daily to bring up new sites, rehearse for demos, do communications testing for exercises, and field test new software. Floor control software has been deployed to 8 of the 18 video gateway sites on the TWB. Deployments to the remaining sites are continuing, although some sites have not yet provided Suns at their locations, and so are unable to use floor control locally. The first operational use of floor control was unsuccessful, due to an incorrect hostname configured on a Sun at DARPA. DARPA subsequently changed the hostname, and additional testing showed no other problems. Three TWB sites have been converted to secure installations for demonstrations of E3 simulation and conferencing. These sites (IDA, Ft. Rucker, and BBN-DWS) are no longer available for regular conferencing on an ad-hoc basis. We do have the ability to switch these sites, with appropriate warning, when necessary for important non-secure activities. During a demonstration in June, IDA and BBN-DWS successfully conducted a secure simulation demonstration for a group at IDA. During June, Ft. Knox, Ft. Rucker, and RADC converted from butterfly to T/20 gateways. These were the last conferencing/simulation sites to make the switch. Only two butterfly gateways remain on the TWB.

Mark Fedor (fedor@uu.psi.com) CONCERT ------- MCNC has developed a draft document for remote conferencing architecture. It will be presented for review in the Remote Conferencing BOF at the July IETF meeting at Boston. The document can be accessed through anonymous ftp from ftp.concert.net. The document is /doc/pv_arch.ps (in Postscript format). CONCERT received an NSF grant providing funds for connecting nine North Carolina Universities/Colleges to the network. Tom Sandoski Cooper [Page 14] Internet Monthly Report June 1992 ISI --- GIGABIT NETWORKING ATOMIC The ATOMIC project took delivery of its first 3-by-3 interhost router (Mosaic mesh) board. Functioning 8-by-8 mesh boards are also now being tested at Caltech. This 3-by-3 router can directly interconnect twelve hosts and should provide approximately 5 Gb/s of routing capacity. AC, Mosiac and UNIX kernel work was done to prepare for the use of N-by-N mesh routers in the ATOMIC network. Router enclosure design and channel-cable adaptor board fabrication were completed earlier this year. Assembly and initial testing of the ATOMIC router prototype will begin in July. Testing will determine mesh router capacity and will provide more interesting topology for the ATOMIC discovery and routing database program, the Address Consultant (AC). Work on the AC in June centered on the automatic discovery and display of network topology and detection/prevention of deadlocks. The AC can now dynamically map the topology of ATOMIC networks and create complete source-routing tables. Automatic interrogation of the AC is implemented within the BSD UNIX kernel, to provide hosts with source routes. Multiple ACs can run simultaneously in different hosts. A distributed election mechanism ensures that only one AC becomes the "controlling" AC. The remainder remain dormant awaiting the possible failure of the controlling AC, at which point a new election occurs. The issue of fault isolation for Mosaic channels in an office environment was considered during June. A document that outlines one approach toward isolation of channel faults was sent to Caltech, where the Mosaic project is designing and prototyping a many-meter Mosaic channel transmission chip. Fault isolation is important since power failures, bugs, attacks and hardware failures are a part of the real networking world.

Ann Cooper (Cooper@ISI.EDU) MULTIMEDIA CONFERENCING The initial implementation of the Connection Control Protocol (CCP) was completed this month and will now be tested over DARTnet. CCP is an experimental application layer protocol designed to facilitate multimedia teleconferencing over the Internet. It orchestrates multiple-user, multiple-media sessions in a distributed manner, providing among other functions a flexible group transaction service, robustness mechanisms for WAN operation Cooper [Page 16] Internet Monthly Report June 1992 and negotiation for heterogeneous end system configurations. We are working with students from USC on software decoding of the compressed video used in DARTnet experiments. Displaying video in a workstation window rather than on a separate monitor facilitates a "personal conferencing" mode. Software decoding will also enable DARTnet experiments employing a larger number of receivers without additional hardware cost. We have completed the decoding routines which will be integrated with packet reception and X-window display software by the students. An article was submitted to Computer Communications Review on the first IETF meeting "audiocast" from San Diego. Meanwhile, preparations are underway for a second audiocast from the Boston IETF in July, this time also including video and expected to reach a much larger audience.

NETLOG, the JvNCnet Trouble Ticket System "Netlog v2.0", a UNIX-based trouble-ticketing system, is now in the public domain and available from anonymous ftp: (Username: your email address and no password). ftp.jvnc.net under 'pub/netlog-tt.tar.Z' All bug reports to "netlog-bugs@jvnc.net". Send email to "netlog-users-request@jvnc.net" if you use this software and want to receive software update notification. Running on Unix systems, Netlog, not based on any database, stores all logs as ASCII text files and its own index system processes the logs. Length of log entry is unrestricted. Netlog uses an open, update, close-ticketing, and informational mechanism. In use at JvNCnet since 1990, the system is fast and efficient. Netlog provides the following functions: Create entry, edit log, read log, list open tickets, search logs, process tickets D. NOCOL, JvNCnet's Network Operation Center On-Line NOCOL v2.0 is available in the public domain via anonymous ftp from: ftp.jvnc.net (128.121.50.7) under ~ftp/pub/nocol.tar.Z. For addition to the updates and bug fixes mailing list, please send email to: "nocol-users-request@jvnc.net". Send comments to: "nocol-info@jvnc.net" Send bugs to: "nocol-bugs@jvnc.net". NOCOL, a collection of network monitoring programs, is designed to run on Unix systems primarily for IP networks. Monitoring agents poll various parameters from any system and appropriately format the data for post-processing. Post processors may be a display agent, automated troubleshooting program, or event-logging program. The display module (nocol) with the monitoring agents is presently available. Cooper [Page 19] Internet Monthly Report June 1992 The monitoring agents can monitor any entity, protocol, or variable. To date, the monitoring agents developed are: IP ICMP monitor (ping or multiping) OSI reachability monitor (OSI ping) SNMP trap monitor IP data throughput monitor Nameserver (named) monitor Monitor for number of terminal server lines in use (for cisco terminal servers using xtacacs) The software is flexible and permits enhancements and development with minimal effort. It is easy to add monitors for DECnet and/or other protocols. The program was evaluated on SUNOS4.1.1, Ultrix, and NeXT. Documentation is under "src/docs". The JvNCnet display can be seen by logging into "nocol.jvnc.net" as user 'nocol'. A "1 4" will give a full display and 'h' will show a brief help screen. Rochelle Hammer (hammer@jvnc.net) LOS NETTOS ---------- We experienced an extended T1 outage on a redundant link because GTE used type A Westel demarc's which would not respond to telco loop up commands. GTE therefore wasted a lot of time trying to repair the wrong end of the line. GTE swapped out the type A Westels for a newer model that responds to remote loop up commands.

The NNSC (NSF Network Service Center) has begun a thorough-going update of the Internet Resource Guide. In June, we distributed 18 new and updated entries. We are sending requests to our contributors to revise and update their entries in the Guide, beginning, with the oldest entries. The NNSC is actively seeking new entries for the Resource Guide. If you know of a resource that should be included, please send a message to "resource- guide@nnsc.nsf.net" and we will be happy to send instructions and a template to the address you suggest. Cooper [Page 21] Internet Monthly Report June 1992 We plan to produce a short version of the Guide as a companion to the present guide. We will also continue the present format with the modifications noted below. For the Compact Internet Resource Guide, we are asking each contributor to prepare a ONE-LINER -- a summary containing only the most essential description of the Resource, in 72 characters or less. The Introduction to the Compact Guide will direct the user who wishes to learn more to the Resource Guide itself, and, at the contributor's option, to longer documents. The Internet Resource Guide has been very well received in the Internet community. The Compact Guide should make it easier for users to get an idea of the Resources that are available, and encourage other Resource providers to contribute entries to the Guide. The NNSC is collecting updates from the mid-level networks for the NSFNET site list for the next issue of the NSF Network Newsletter. On June 8th, the Washington Post published an article on the Internet. The NNSC Staff has received more than fifty requests for information as a result of that article and we are still receiving requests from the article "Applying the Internet" that appeared in Byte Magazine last February.

With the completion of the RS/960 DS3 interface upgrade in May, the cutover of additional traffic from the T1 to the T3 network resumed in June and is proceeding as quickly as possible. The number of networks configured and announced to the T3 network continues to increase. Midlevel traffic cut over from the T1 to the T3 backbone included NorthWestNet, Sprint/International Connections Manager, and Alternet. The T3 backbone is now carrying nearly double the packet load of that of the T1 backbone. With the upgrade complete and the T3 network stable, several performance and functional enhancements have been administered during June. Improvements to the routing daemon and SNMP daemon were made. A remaining problem on the T3 network is the FDDI adapter performance and stability. Due to the complexity of the T3 adapter upgrade, we chose to defer the FDDI upgrade until August to ensure operational stability. Cooper [Page 23] Internet Monthly Report June 1992 Statistics on network traffic and configured networks ===================================================== The total inbound packet count for the T3 network was 10,736,059,912,up 29% from April. 220,593,003 of these packets entered from the T1 network. The total inbound packet count for the T1 network was 5,761,976,518, down 16.7% from May. 536,009,585 of these packets entered from the T3 network. The combined total inbound packet count for the T1 and T3 networks (less cross network traffic) was 15,741,433,842, up 0.9% from April. Currently there are 5801 IP networks configured in the policy routing database for the T1 network, and 3966 for the T3 network. Actual announced networks to the backbone varies and is currently 2750 for T3 and 4425 for T1. NOC Problem Reports =================== The number of problem reports that result in NOC trouble tickets (total all priority classes) for the T3 network remains constant at 10-20 per week, and for the T1 network it remains at the 15-20 rate per week. T1 Backbone Status ================== The T1 backbone's reliability is not as good as T3, due largely to increased route processing on the RCP nodes. The full load of routes is still being carried by these machines, and they are experiencing congestion and performance problems to some degree. Improvements have been made to the routing software to accomodate protocol upgrades (ie. BGP2). T3 Routing Daemon Software Status ================================= Activities related to the rcp_routed software in June emphasized correcting software problems involving routing instability, and monitoring & correcting routing table integrity problems. There were many bug fixes applied to the routing daemon over the last three months. Monitoring of routing integrity consists of data collection of the full netstat table to find route flapping problems within the backbone and within peer networks, BGP disconnect problems, and external network metric problems. Additional work is underway to collect full routing tables from backbone nodes to be processed Cooper [Page 24] Internet Monthly Report June 1992 using a relational database system. This system generates reports on the statistical use of primary routes, reliability of network announcements to the backbone, and long term statistics on inter- domain routing announcements and growth. A number of improvements and bug fixes have been made to the T3 routing software over the last two months. Highlights included: fix to allow an ENSS that is isolated from the backbone to stop announcing default to peers, better handling of router adapter failures, preventing overruns of external BGP messages sent to external peer routers, gracefully dropping bogus external routes to backbone ENSS nodes, correct response to external metric selection problem for nets announced at same metric from multiple peers, problem with interaction between BGP and EGP for peers in the same Autonomous System, hashing route table efficiency improvements, two routes with same AS path are now both installed to allow backup, BGP-2 PDU size increased from 1024 to 4096 bytes, route from BGP and EGP with same metric now prefers BGP route, better handling of next hop behind peer router and shared network, BGP update packet format fix, fix to BGP 1-2 version negotiation, eliminated chance of BGP disconnects during IGP transitions, eliminating BGP disconnects if peer router is too busy, better response to route instabilities upon failure of T1 interconnect or ENSS, and autorestart of the routing daemon in the event of a crash. As a result of the monitoring and analysis effort along with the actual software changes, reliability and route integrity has improved dramatically on the T3 network over the last month. RS/960 DS3 On-Card Memory Problem ================================= A batch of bad memory chips have been found to result in memory parity errors on a few interfaces. Five of these cards have been replaced as the problems have been identified. Diagnostic microcode has been developed to detect the problems in advance, and nodes are being scheduled for diagnostics to be run over the next few weeks during routing configuration update scheduled windows. DSU Synchronization and CRC/alignment Problem ============================================= A problem that causes logical link failures has been traced to a clock synchronization problem on the T3 Technologies DSU's during clock master/slave transitions. This problem occurs very infrequently and has been reproduced using a newly installed circuit on the T3 research network. Enhanced instrumentation has been added to detect this problem, and work is in progress to Cooper [Page 25] Internet Monthly Report June 1992 correct it. End-To-End Packet Loss Analysis =============================== Researchers at University of Maryland recently conducted some experiments and noticed periodic and random packet loss and packet duplicates when using the T3 network. There were two problems traced to a bridge device and an ethernet problem on the SURAnet ethernet. Peer router problems causing some packet loss during routing updates at NEARnet were identified and are being corrected. Also some packet loss on the T3 ENSS FDDI interface at Stanford was identified. This is due to an FDDI card output buffering problem and might be addressed prior to the FDDI upgrade in August. FDDI Adapter Upgrade ==================== Although the T3 adapters have been upgraded from older technology to the new RS960 adapter technology, the FDDI adapters in the ENSS nodes have not yet been upgraded. The older FDDI adapters continue to suffer from performance on reliability problems. The new RS960 FDDI adapter is scheduled to be installed as part of a field trial on July 20th. Following this field trial, we expect to upgrade the older FDDI interfaces with the new RS960 interface adapters in early August. There are currently five T3 ENSS sites that are using FDDI interfaces in production. SNMP Daemon Changes =================== A new version of the SNMP daemon for the T3 network was installed on June 26. This version supports MIB-II variables for the T/960 ethernet cards (ifInUcastPkts, ifOutUcastPkts, and ifInErrors), and also includes enhanced configuration support for monitoring T3 DSUs. A new SNMP client for the NOC to control the T1 Cylink ACSUs which are part of the T3 backbone has been implemented. This avoids use of a separate dial-in connection to these CSUs. New SNMP variables have been added to furthermonitor the DSU synchronization problem mentioned above. Mark Knopper (mak@merit.edu) Jordan Becker (becker@ans.net) Cooper [Page 26] Internet Monthly Report June 1992 NSFNET/INFORMATION SERVICES --------------------------- NSFNET Project Information Services At the close of June, 5739 networks are announced via the NSFNET infrastructures. Of this total, 3920 nets are announced via the T3 backbone, and 2002 nets have foreign locations. Guests at the Merit Network Operations Center (NOC) included Mr. Tadeusz Wegrzynowski, Managing Director of the Warsaw University Computer Center and Administrator of the PLEARN Node, and members of the Department of Defense Security Administration. The Information Infrastructure and Technology Act of 1992 was introduced in the U.S. Senate by Al Gore (D-TN) on 1 July. This act builds on the High-Performance Computing Act introduced by Senator Gore in 1988 and signed into law last year. The new bill would ensure that the technology developed by the High-Performance Computing Program is applied widely in K-12 education, libraries, health care, and industry, particularly manufacturing. The text of this legislation is available for anonymous ftp from the host nic.merit.edu in the directory /nren/iita.1992 as the file gorebill.1992.txt. This bill is also available via electronic mail by sending e-mail to nis-info@nic.merit.edu: ignore the subject field, and specify send gorebill.1992.txt as the first line of text. "Making Your NSFNET Connection Count," sponsored by Merit Network, Inc. and hosted by NevadaNet on June 1 and 2 in Las Vegas, was well received by 105 attendees. The keynote address, "Supercomputer Visualization and Networking," was given by Donna Cox, Director of Numerical Lab Programs at the National Center for Supercomputer Applications.

Merit K-12 Outreach Coordinator, Dana Sitzler, participated in a break-out session on networking for K-12 education. Elise Gerich of Merit Internet Engineering introduced "Internetworking with TCP/IP." Pat Smith, Steve Burdick, Susan R. Harris, and Fred Swartz, all of the Information Services staff, attended the proceedings and were instrumental in the organization and success of the seminar. The next Merit Networking Seminar is Cooper [Page 27] Internet Monthly Report June 1992 scheduled for October 19 and 20 in Ann Arbor, MI. Electronic mail inquiries may be sent to seminar@merit.edu or phone 1-800-66-MERIT for further information. Laura Kelleher, Merit/NSFNET Information Services, and Rick Schmalgemeier, Merit Technical Support Group, met in Bloomington, Indiana with other members of the TopNode initiative from the Coalition for Networked Information (CNI) and Indiana University. TopNode is an Internet directory project, with current efforts focused on defining the data elements for cataloguing directory and application information about Internet resources. Pat Smith, Merit/NSFNET Information Services, and Elise Gerich, Merit Internet Engineering, participated in the Canadian National Networking 1992 conference held in St. John's, Newfoundland. Smith's presentation cruised the resources of the Internet, while Gerich gave a technical overview of the NSFNET. As the NSFNET representative to the CA*net meeting which convened in Montreal, Quebec, Gerich gave the NSFNET update. Gerich and Jim Williams, Merit Associate Director for National Networking, traveled to Tokyo, Japan for the International Networking Conference, INET '92. Gerich participated on the policy panel discussing international connections. Gerich also represented Merit/NSFNET at the FEPG/EOWG meeting in Washington, D.C. at the end of June. A fact finding meeting to discuss NSFNET requirements for connectivity to Russia was sponsored by the High Energy Physics group at SDSC. Mark Knopper, Manager of Merit Internet Engineering, and Enke Chen of IE attended. Jo Ann Ward (jward@merit.edu) SAIC ---- The GATED implementation of IDPR has been completed. An end document describing the available functionality, differences from the spec, and needed future development will be forthcoming. The release will be made available pending coordination with Cornell. Extensive testing with SRI shook loose several bugs, but also raised some architectural questions. These will be discussed at the upcoming IETF. Planned Activities: Completion of end documents and release of the software to Cornell. Robert "Woody" Woodburn, Cooper [Page 28] Internet Monthly Report June 1992 UCL ---- Ian Wakeman and Mark Handley attended INET 92 in Kobe, Japan, and gave papers on "Analysis of UK-US Transatlantic Traffic" and "Multimedia Conferencing: From Prototype to National Pilot". These can be ftp'd from cs.ucl.ac.uk:docs/rntraffic.ps.Z and cs.ucl.ac.uk:car/car-inet92.ps.Z both (Unix) compressed (Adobe)postscript Peter Kirstein, Paul Tsuchiya and Steve Hardcastle-Kille also attended. Work is in hand on a new multicast routing algorithm, called Core Based Trees (crowcroft, ballardie, tsuchiya). John Crowcroft (j.crowcroft@CS.UCL.AC.UK) UNIVERSITY OF DELAWARE ---------------------- 1. The end2end research group meeting was held at the University of Delaware on 9-10 June. 2. Measurements continue with the NTP version-3 daemon for Unix as modified to support a one-pulse-per-second signal generated by some timecode receivers and precision oscillators. Preliminary results were presented at the end2end research meeting. While incidental jitter has been reduced to a few tens of microseconds, the frequency stability, typically a few parts in 10**7, is limited by the oscillator wander and crystal aging found in typical computer clocks. 3. A comprehensive technical report on precision computer timekeeping can be found on louie.udel.edu in the compressed tar archive pub/ntp/doc/timex.tar.Z. The files included are in PostScript format and are rich in diagrams and equations. 4. Our burgeoning antenna farm at two sites now feeds two WWVB timecode receivers, three WWV receivers, two GPS receivers, two LORAN-C receivers and a CHU receiver. Aging fuzzball primary time server dcn1.udel.edu has been replaced by a dedicated Sun IPC at the same address and synchronized to WWVB. Senile fuzzball primary time server dcn5.udel.edu has been replaced by a dedicated Bancomm bc700LAN integrated NTP time server at the same address and synchronized to GPS.

section of the Internet Monthly is devoted to efforts working to develop directory services that are for, or effect, the Internet. We would like to encourage any organization with news about directory service activities to use this forum for publishing brief monthly news items. The current reporters list includes: o IETF OSIDS Working Group [no] o IETF DISI Working Group [no] o Field Operational X.500 Project [no] - ISI - Merit - PSI - SRI o National Institute of Standards and Technology [included] o North American Directory Forum [no] o OSI Implementor's Workshop [no] o PARADISE Project [no] o PSI DARPA/NNT X.500 Project [no] o PSI WHITE PAGES PILOT [no] o Registration Authority Committee (ANSI USA RAC) [no] o U.S. Department of State, Study Group D, [no] MHS Management Domain subcommittee (SG-D MHS-MD) Tom Tignor (tpt2@isi.edu) DS Report Coordinator NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY ---------------------------------------------- During June the Pilot DSA was up and running almost continuously. Starting in July, we will collect statistics on Pilot usage. These will be reported beginning in August. Work has progressed on extending the scope and accessibility of the Pilot. An account has been set up to enable dialup DUA access for other agency staff. On login, the Widget DUA user interface is automatically brought up, providing access to the Pilot DSA. Some details remain to be worked out, but dial-up access is expected to begin by the end of July. We are continuing to pursue TP4/CLNP accessibility to the Pilot DSA over FTS A and B. The impediments have to do with establishing an OSI routing path from the NIST FTS access machine to the machine running the Pilot DSA. Cooper [Page 35] Internet Monthly Report June 1992 NIST X.500 Implementation ------------------------- Improvements were caried out in two areas of the Custos code during June. A problem with the result of the List operation, in which the origin of the information carried in the result was incorrectly flagged, was corrected, and the code for the Search operation was enhanced to enable Search to operate on all naming contexts, regardless of whether the naming context has been loaded into memory at startup. Future Plans ------------ We have continued our work with NASA, DHHS, and other agencies to establish Internet and FTS2000 connectivity to the pilot DSA. We have begun a dialog with Dallas Day of Wright-Patterson AFB on the integration of his base's OSIWare DSA into the Pilot, and have had similar discussions with Doug Harsha from the Department of Agriculture in Ft. Collins, CO. We have also initiated discussions with NIST's Computing and Applied Mathematics Laboratory on a collaborative venture to provide a NIST-wide white pages directory service. The plan is to provide telephone/email/addressing information on NIST staff to the desktop, via PC and Macintosh based DUA packages. We expect that this can serve as a model for other agencies interested in deploying the OSI Directory.

A gleam of pale sand, a whisper of deep flowing waters, and a farther glimmer of more sands beyond them challenged our advance. We had come to a "grapevine ferry." The scow was on the other side, the water too shoal for the horses to swim, and the bottom, most likely, quicksand. Out of the blackness of the opposite shore came a soft, high-pitched, quavering, long-drawn, smothered moan of woe, the call of that snivelling little sinner the screech-owl. Ferry murmured to me to answer it and I sent the same faint horror-stricken tremolo back. Again it came to us, from not farther than one might toss his cap, and I followed Ferry down to the water's edge. The grapevine guy swayed at our side, we heard the scow slide from the sands, and in a few moments, moved by two videttes, it touched our shore. Soon we were across, the two videttes riding with us, and beyond a sharp rise, in an old opening made by the swoop of a hurricane, we entered the silent unlighted bivouac of Ferry's scouts. Ferry got down and sat on the earth talking with Quinn, while the sergeants quietly roused the sleepers to horse. Plotinus is driven by this perplexity to reconsider the whole theory of Matter.477 He takes Aristotle¡¯s doctrine as the groundwork of his investigation. According to this, all existence is divided into Matter and Form. What we know of things¡ªin other words, the sum of their differential characteristics¡ªis their Form. Take away this, and the unknowable residuum is their Matter. Again, Matter is the vague indeterminate something out of which particular Forms are developed. The two are related as Possibility to Actuality, as the more generic to the more specific substance through every grade of classification and composition. Thus there are two Matters, the one sensible and the other intelligible. The former constitutes the common substratum of bodies, the other the common element of ideas.478 The general distinction between Matter and Form was originally suggested to Aristotle by Plato¡¯s remarks on the same subject; but he differs325 from his master in two important particulars. Plato, in his Timaeus, seems to identify Matter with space.479 So far, it is a much more positive conception than the ?λη of the Metaphysics. On the other hand, he constantly opposes it to reality as something non-existent; and he at least implies that it is opposed to absolute good as a principle of absolute evil.480 Thus while the Aristotelian world is formed by the development of Power into Actuality, the Platonic world is composed by the union of Being and not-Being, of the Same and the Different, of the One and the Many, of the Limit and the Unlimited, of Good and Evil, in varying proportions with each other. The Lawton woman had heard of an officer's family at Grant, which was in need of a cook, and had gone there. [See larger version] On the 8th of July an extraordinary Privy Council was summoned. All the members, of whatever party, were desired to attend, and many were the speculations as to the object of their meeting. The general notion was that it involved the continuing or the ending of the war. It turned out to be for the announcement of the king's intended marriage. The lady selected was Charlotte, the second sister of the Duke of Mecklenburg-Strelitz. Apart from the narrowness of her education, the young princess had a considerable amount of amiability, good sense, and domestic taste. These she shared with her intended husband, and whilst they made the royal couple always retiring, at the same time they caused them to give, during their lives, a moral air to their court. On the 8th of September Charlotte arrived at St. James's, and that afternoon the marriage took place, the ceremony being performed by the Archbishop of Canterbury. On the 22nd the coronation took place with the greatest splendour. Mother and girls were inconsolable, for each had something that they were sure "Si would like," and would "do him good," but they knew Josiah Klegg, Sr., well enough to understand what was the condition when he had once made up his mind. CHAPTER V. THE YOUNG RECRUITS Si proceeded to deftly construct a litter out of the two guns, with some sticks that he cut with a knife, and bound with pawpaw strips. His voice had sunk very low, almost to sweetness. A soft flurry of pink went over her face, and her eyelids drooped. Then suddenly she braced herself, pulled herself taut, grew combative again, though her voice shook. HoME²Ô¾®Ïè̫ʲôÐÇ×ù ENTER NUMBET 0016www.ff951.com.cn
