The PSRG reviewed the preparations for the Internet Society Symposium on Network and Distributed System Security, sceheduled for February 16-17, 1995 in San Diego. Jim Ellis, the symposium general chair, joined the discussion via phone from Pittsburg, and provided a status update. The group also recieved briefings my members on various topics, including the ACM Crypto Policy panel, DoD Goal Security Architecture documents, Secure HTTP, a software key escrow proposal from TIS, the SILS (IEEE 802.10) key management protocol, and the followon to the RACE program in the EU. The group reviewed the status of the Internet Security Architecture document and made plans to revise and release several of the chapters of this document later in 1994. Finally, the PSRG devoted some time to discussion of security requirements and mechanisms for use with autonomous information retrieval agents (e.g., Knowbots), and made plans to continue discussion of that topic in the future. The next meeting of the PSRG is schedule for late September or early October at NIST. Steve Kent INTERNET ENGINEERING REPORTS ---------------------------- 1.

The process of CIDR aggregation continued in June. An increase in the ANSnet forwarding table size of 1% was observed during the month of June. April Backbone Traffic Statistics ============================== The total inbound packet count for the ANSnet (measured using SNMP interface counters) was 61,782,591,066 on T3 ENSS interfaces, up 2.62% from May. The total packet count into the network including all ENSS serial interfaces was 70,462,985,795 down .81% from May. Router Forwarding Table Statistics ================================ The maximum number of destinations announced to the ANSnet during June was 17,791 up 1% from May. This modest increase in the monthly forwarding table size indicates the possible slowing of CIDR aggregation. The number of network destinations configured for announcement to the ANSnet but never announced (silent nets) during June was 14,265. BGP-4/CIDR Deployment Status ============================ No new autonomous systems began exchanging routing information with ANSnet via the BGP-4 protocol during June. As of July 6 '94, we have observed the withdrawal of 6,081 class based destinations from the ANSnet router forwarding tables that are now represented by 952 configured aggregates. Among these configured aggregates: Cooper [Page 9] Internet Monthly Report June 1994 862 of these are top-level aggregates (not nested in another ggregate). 751 of these are actively announced to ANSnet. 653 of these have at least one subnet configured (the other 98 may be saving the Internet future subnet announcements). 540 of these have resulted in the withdrawal of at least one configured more specific route. 526 of these have resulted in the withdrawal of 50% of their configured more specific routes. 510 of these have resulted in the withdrawal of most (80%+) of their more specific routes. For up-to-date information is available from merit.edu: pub/nsfnet/cidr/cidr-savings. For further details on these CIDR aggregates, see merit.edu:pub/nsfnet/cidr/nestings.announced for full listings. Routing Stability Measured on the T3 Network ============================================ Internal routing stability measurements are made by monitoring short term disconnect times (disconnects of five minutes duration or less). This is intended as a measure of overall system stability rather than complete connectivity. These measurements had previously been based on rcp_routing logs and had not been collected since February '94 when gated was deployed. The month of June is the first complete month to be covered by this report since then. June was the most stable month recorded since this data was collected (since January 1993).

This was due to there being no new router system software deployment, no new routing software deployment, fully dynamic reconfiguration, and no major circuit or equipment problems in the ANS backbone. External route flap reports have been completely rewritten to accomodate differences in the way routes are withdrawn in BGP-4 (there is never an AS path included) and the support of CIDR. The previous reports are described in: ftp.ans.net:/pub/info/routing-stats/ExternalRouteFlapReports The improved reports have been sent to AS~s bordering AS 690 since late May. Reliable data is available for Jun 8th on. The monthly summary reporting programs have not yet been fully converted. Summaries will be available in the July report. A brief description file and the notable unstable networks for each day Cooper [Page 11] Internet Monthly Report June 1994 from June 8th on can be found in the directory: ftp.ans.net:/pub/info/routing-stats/daily-reports Notable Outages for June '94 ============================ UNAM suffered extended circuit outages on 06/06 and 06/18. E222 (InterNIC) suffered an extended circuit outage on 06/17. E158 (MHPCC) suffered an extended outage due to site maintenance on 06/18. E138 (Atlanta) lost T3 connectivity due to hardware problems on 06/25. UNAM suffered an extended outage due to site maintenance on 06/29.

Point of contact: Craig Partridge, craig@bbn.com More complete reports of the above projects will be provided in the future. This month, BBN provides a more elaborate report of its Scalability project. The goals of this project are to study the internetworking requirements of distributed interactive simulation (DIS) and the capabilities of alternative internet technologies/architectures to fulfill these requirements. Scalability With the pressing need to ensure that the Defense Simulation Internet (DSI) is ready to support this Fall's STOW-Europe (STOW-E) exercises, emphasis on BBN's Scalability Task has shifted. Earlier, we were focusing almost exclusively on the long-term networking requirements of distributed interactive simulation (DIS). These days, we are focusing on finding the convergence between current DSI capabilities and STOW-E capacity and latency requirements. The DSI is complex and has many configuration options. Moreover, it is undergoing multiple upgrades. The bandwidth of the U.S. backbone has recently been doubled (to 2xT1), and there are plans to increase the bandwidth of the European segment, so that it will be uniformly provisioned with links of at least T1 capacity. The NES end-to-end encryption units are being upgraded to enable an approximate 50% increase in throughput capacity. New software is being deployed in the BBN T/20 gateways, and one of the benefits of this new software is the ability to use multiple NESes in parallel, thereby further increasing the capacity of the simulation site access links. While these changes are occurring, BBN is testing the performance of DSI technology in the laboratory. Over the past month, we have been subjecting individual DSI components to throughput testing in which we have identified both unidirectional and bidirectional throughput limits for a variety of packet sizes. Currently, testbed configurations of typical DSI end-to-end paths are being assembled, and traffic generators are being used to find the upper limits of loss-free throughput. We are also recommending additional changes to DSI configuration to enable the accommodation of greater numbers of participating sites and higher volumes of traffic. In early July, we will be constructing traffic generators that represent the Government's best predictions of actual STOW-E traffic volumes, packet sizes, and arrival behavior. These will be applied to laboratory set-ups to further tune DSI capacity to meet Cooper [Page 13] Internet Monthly Report June 1994 the needs of STOW-E.

Frazer DIRECTORY AND DATABASE SERVICES ------------------------------- Our users frequently ask us why various well-known organizations cannot be found in our whitepages directory services. We use a number of different tools to provide whitepages service. They have various advantages, but they also have some disadvantages. One of the tools we use is X.500. X.500 is a directory service based on international standards. Its model of the world is a tree - the top of the tree consists of entries for countries, and organizations can be entered under the countries. In some countries, there are entries for geographical subdivisions (e.g. states in the USA), and organizations can be entered under these subdivisions. Our X.500 server is part of a world-wide directory tree that includes more than 1 million entries for individuals. Still, we must remember that these 1,000,000+ entries do not contain everyone on the Internet. These entries are maintained by various organizations that run X.500 servers for their own users. Since not every organization on the Internet runs an X.500 server, there are many people who cannot be found in X.500. If you have tried to find someone in X.500 and received a message saying that the organization cannot be found, it does not mean that the organization does not exist or that it is not connected to the Internet - it probably just means that the organization does not support an X.500 server. Another popular tool we support is Netfind. Netfind was developed at the University of Colorado by Mike Schwartz, and makes use of common Internet tools like "finger" to find people. It does not depend on directories that have been built by organizations connected to the Internet; rather, it searches through a number of machines on the net, looking for a machine that knows about the target person of the search. It uses various rules and information it has gathered to narrow the search to a likely set of machines. Because Netfind does not depend on directories set up by organizations attached to the Internet, it can find people that aren't in any directory. However, Netfind does depend on tools like finger, and many installations have turned off finger for because of privacy or security concerns. For this reason, Netfind Cooper [Page 18] Internet Monthly Report June 1994 too can fail to find people even though they are connected to the Internet. A reminder - if you would like to help the Internet community find a resource that you offer, send mail to admin@ds.internic.net and we will send information about listing your resource in the Directory of Directories. by Rick Huber REGISTRATIONS SERVICES ---------------------- I.

Display Server Investigation ---------------------------- A graduate student, Munnangi S. K. Reddy, was hired to investigate how to partition the X11 Display Server. The objective is to split the server into two parts: "higher" and "lower". He will them implement a server along those lines. The "lower", or more fundamental bitmap manipulation portion of the server, we desire to closely associate with the frame buffer, interfacing it to the network, so that the physical display device becomes a network peripheral. The analogy would be to transform the bitmap-manipulation procedures within the X-server into remote procedure calls (RPCs). With the advent of gigabit LANs, the focus on minimizing network traffic is no longer as important. One of the research questions that we are asking is: Is it practical to substitute a gigabit LAN for a system bus? In terms of a display interface design, this asks whether or not the raster-op level routines can be called via RPCs. Evidently, X is not ideally partitioned for this as was the Sun Pixrect display driver. However, X has become a standard and it does not seem realistic to use anything but X at this juncture. The implementation will not be strightforward. Many procedures need to be ported and the server partition made at a point where few up-calls will occur from the lower part of the server to the upper part, yet the partition must be low enough to fairly test bus substitution. LANai 1.1 Software Development ------------------------------ The focus of LANai development during the past month has been on implementing a light-weight reliable-packet protocol. In this case, the protocol executes "inside" the LAN. A higher-layer protocol that passes a packet to it, inherits reliable transmission properties. This offloads that task from the host itself. Cooper [Page 20] Internet Monthly Report June 1994 This work is designed to test the proposition that a better approach to obtaining higher RPC performance within a gigabit LAN may be to perform the reliability function within the LAN itself, with the retransmission timeout and retransmission taking place underneath the host. Since RPCs are the cornerstone of message- based distributed computing, the success of this approach would have strong positive effect on cluster computing. RPCs tend to be small packets. The focus of performance here shifts from TCP's focus on reliability and high bandwidth, to a focus on reliability and a high number of packets per second. This partitioning is made possible with the new facilites of the LANai. It is accomplished by utilizing a time-event driven facility within the LANai, which was discussed last month, and by adopting a light-weight source-interface to destination-interface protocol that allows one unacknowledged reliable message packet to be outstanding on a connection. While that is not a good idea on slower or long-haul networks due to its negative effect upon throughput, for a gigabit LAN the round-trip delay can be sufficiently short that for RPCs the limitation may be more theoretical than practical. The merits/failings of this approach will be closely tied to the performance of the system. Implementation is more or less complete and debugging is underway. Performance figures should be available by the time the next monthly report is written. Greg Finn Eight RFCs were published this month. RFC 1625: St. Pierre, M., (WAIS,Inc.), J. Fullton (CNIDR), K.

THE US DOMAIN Domain Names for Local Government Agencies The locality based domain names are the fundamental concept for naming in the US Domain. ...US. Within the locality namespace are cities and counties. .CI...US. .CO...US. A "CI" branch was created for city government agencies, and "CO" was created for county government agencies. Due to the fact that GOV is designed for Federal agencies only, many local governments have already begun registering in the US Domain.

NYSERNET SPONSORED PROJECT UPDATE NYSERNet initiated Project C.A.R.E. (Community Accessible Rural Education) through funding provided through the offices of State Senator Charles D. Cook. With this project, NYSERNet will coordinate the provision of Internet connections and training to [eight] schools in New York's 40th district to ensure that rural schools can offer the same opportunities currently enjoyed by larger and more [a]ffluent school districts. Cooper [Page 29] Internet Monthly Report June 1994 NYSERNet also coordinates a variety of K-12 projects. One that has received considerable media coverage and nationwide interest is the Women In Science, Engineering, and Math Mentors Program. The program was piloted last spring and is concluding its first full school year program on June 7th, 1994. Through the program, high school girls are electronically connected to a multitude of professional women for a five month period of interviewing and dialogue. They also meet in person for a day of shadowing in the workplace and for the opening and closing luncheon activities and training. The program has recently received a grant from the American Association for the Advancement of Science (AAAS) to expand this year's program to include young women from the government housing projects in Rochester. There are plans to extend this program to statewide participants regionally through our affiliates.

John Crowcroft (j.crowcroft@CS.UCL.AC.UK) Cooper [Page 31] Internet Monthly Report June 1994 USER SERVICES REPORT -------------------- Trip Report 17th RIPE Meeting - Amsterdam, The Netherlands January 24-26, 1994 Joyce K. Reynolds USC/Information Sciences Institute The 17th RIPE Meeting The 17th RIPE Meeting was held in January 1994 in Amsterdam, The Netherlands. Review and approval of the agenda and minutes of the last meeting was first, with parallel sessions starting after general plenaries. 1. RIPE NCC Report by Daniel Karrenberg During the last quarter, the RIPE NCC Staff included Daniel, Anne Lord, Tony Bates, and Marten Tempstra, with NCC funding. Now, the RIPE NCC also has PRIDE (Policy Based Routing Implementation and Deployment in Europe) funding (January 1994). New staffers include Geza Terchany and Geert Jan de Groot. The RIPE NCC basically works as one team, despite the funding situation. There are no split personalities. Since the NOC operations started two years ago, the Internet has tripled in size. The number of Internet service providers has increased by that factor, also. The number of books on the Internet has grown even faster. Meanwhile, the staffing of the NCC core of services has stayed the same. There is a problem with this. The NCC core of services needs more staff in 1994. Geza is only a six months hire. The RIPE NCC needs more trained staff. The RIPE NCC Internet Registry (IR) Registry - revised registration procedures - application for blocks of Class Cs need extra checking - RIPE handles will happen Address Space - approximately 18 per week - approximately 100 Class Cs per working day Cooper [Page 32] Internet Monthly Report June 1994 Local Registry - 83 registries (24 "last resort") - still do most of the work - more large requests Database Objects Processed Quarter 1 Quarter 2 Quarter 3 Quarter 4 27938 28110 58189 42767 The new "automatic" software has proven itself. There has been excellent feedback from the community. There has been an increase in the update frequency. A database is needed to provide documentation and software release. On the other hand, coverage still needs to be improved. Document Store The document store is well used, with continuing efforts to improve the presentation. Presentations and publications for a wide audience are requested and welcomed. Joint Projects GISD (Generic Interface Service Description) needs continuation. An editor is being sought (funding is available). The PRIDE project is going very well. Tools have been released (prtractroute, prcheck). There is a prpath prototype and documentation being created (guides, courses). Infrastructure work is going on, with additional office space being provided this month (January 1994). The computing center is utilizing used SUN ELCs. There has been an increase in incoming faxes and electronic mail. Odds and Ends NCC Connectivity: NCC --> NIKHEF --> SURFNET-EMPS Concerns within the community include: universal connectivity commercial advantage of NCC proposals NCC neutrality Cooper [Page 33] Internet Monthly Report June 1994 These problems are being addressed. 2. RIPE NCC Funding - Rob Blokzijl Not all funds have been secured yet. Service providers are urged to contact the RIPE NCC. Daniel Karrenberg needs an increase in staff. This must be resolved this year. The RIPE NCC Activity Plan (1994-1995) is still being worked on. One or two comments have been received. Basically, those comments pointed out spelling and grammatical errors, and that's it. A short discussion could be worth while, but approval should come back by this coming Wednesday (see Appendix for the Draft plan). 3. Policy Based Routing Implementation and Deployment in Europe (PRIDE) - Tony Bates The organization of PRIDE consists of only one FTE for the first three months. One-third of the time is allotted to Daniel. The second position is filled by Marten Tempstra, which started January 1994. The PRIDE plan is available. Tool Status The current release of PRIDE Tools is 1.0.3. There have been general fixes. Keep those suggestions coming. The PRIDE mailing list is set up, including an archive. The general PRIDE FTP directory: ftp.ripe.net: pride/tools : pride/docs : pride/reports The Future The first PRIDE Guide and Course is due in week ten (10). It is on schedule, and general discussion and ideas have begun. The structure is related to RIPE-81++. An alpha version of the "prpath" tools is in test mode at the NCC. PRIDE will detail all possible paths from A to B, according to information compiled. Related Activities The RIPE PR/Database and the software and documents are an integral part of the PRIDE work. The population of the RIPE RR (Routing Registry) is by non-RIPE service providers. There has been a pilot set up with Alternet. More are needed. Daniel Cooper [Page 34] Internet Monthly Report June 1994 and Tony will attend the regional techs meeting to discuss PRIDE and related issues. Quick Summary The Route Server (RS) project is officially over, but the PRIDE project is operating the RS. The Route Server itself is fully operational. The new "gated" is a considerable improvement in both performance and stability. It also contains support for BGP4 in detail. - A large amount of alpha testing done in "Kludge" mode as per RIPE-03. - All working automatically. Is it doing anything? Yes. It is acting in "pilot" mode for NORDUNET for over two months as the secondary NEXT_HOP provider for updates to AS690. What's Next? - Use of PRIDE tools to build RS configurations - Work on CIX RS/RR - Possible project to set up a second European route server at the GIX. - Combined as an RR. - D-GIXs, et al? 4. Network Information Discovery for Users Support (NIDUS WG) The NIDUS WG, chaired by Nandor Hovarth, held a session at this RIPE meeting. A. Blasco Bonito lead a continued discussion regarding GARR's Network Resource Guide. At the last RIPE meeting, the group felt that this resource guide could have two paths to follow. -continue building on the guide as is and keep enhancing it -find out if a pilot project group needs to be started to help in the development of the specialization of each item within the guide -would RIPE be the forum for this pilot or RARE? A. Blasco Bonito updated the group that this effort has now included discussion on an on-line modified WAIS server. The reaction so far has been positive. This work has been shown to RARE, but no one from GARR had a chance to attend the RARE meetings in Warsaw, so there has not been any opportunity to continue talks with RARE. Meanwhile, Cooper [Page 35] Internet Monthly Report June 1994 GARR has decided to go ahead with the document at the national level. This includes setting up a WAIS/Gopher server, developing a simple to use template on a national level and circulating it. A question was raised, "Are people following through and filling out and returning the template?" Yes. Response has been positive. Joyce Reynolds presented a report on the IETF User Services Area activities and meetings held during the Houston IETF in November. She also reported on the EARN Network Services Conference, the EARNINFO Group, and the RARE ISUS WG meeting, all held in Warsaw, Poland in October (see Appendix). 5. Connectivity Working Group (Status Report on Russia) - Rob Blokzijl Three different endeavors that are currently going on in Russia with the help from outside organizations were discussed at this session. Rob provided information on the RELCOM, FREENET, EUnet, and NSF. A description of the Radio-MSU Network effort (DESY-Germany) was discussed, as were the efforts of the NASA Goddard Space Flight Center's (GSFC) involvement in Russia. RELCOM/FREENET/EUnet/NSF RELCOM is the commercial line from Moscow to St. Petersburg. The RELCOM node is only a copper wire connection. It will be fiber in a few weeks (60Km in length). The first stage will include fifteen nodes (Steve Goldstein and NSF helped). FREENET, EUnet, RELCOM, NSF are all trying for more fiber instead of copper wire. The figure below shows the current schema. There have been attempts to link fiber to the southern area (M9), but there are problems with the length of cable. Rob (as a NSF representative) is waiting for a proposal from Russia regarding expanding the cable. Rob mentioned that Russia has certain components that are still missing which are critical to their connectivity. They need full completion of the project before connectivity can become a reality. Cooper [Page 36] Internet Monthly Report June 1994 ------------ | EUnet | | (256Kbps)| ------------ o St. Pete \ \ \ o Kiev ------- o T1 \ / \ / o Moscow / \ / \ / \ / \ / \ /-------------ITEP \ / o M9 In the figure above, Rob mentioned that the first working connection was the RELCOM/St. Pete line. The speed of the modems ranges from 2Mb up to 8Mb (they are mostly 4Mb). The routers have not been ordered yet. Once they are ordered, it will take up to six months for them to arrive. The routers are an integral part to the connectivity. Currently, there is just a point to point connection. Radio-MSU Network Radio-MSU Network, which is a combined satellite/microwave network has been set up between three institutes in the Moscow region and DESY (Germany). Cooper [Page 37] Internet Monthly Report June 1994 ------------ | Internet | ------------ | | ------------- | DESY | | Germany | | (Hamburg) | ------------- \ \ \ \ \ 256Kbps links (December 1993) \ \ \ \ \ ---------- | Moscow | ---------- | | ---------- | Moscow | ---------- | | ---------- | Moscow | ---------- The problem of getting the low speed for the Moscow region is that it has very cheap satellite links from the former Soviet Union. Rob has letters from five separate institutions to work on the satellite links. Yet, what will be the reliability of the routers? Another problem for discussion is the commercial versus the non-commercial ideas. The funding by DESY/DFN (the Germany Ministry of Research and Technology) is improving network connectivity. Work is in process of cleaning up the other lines. The NASA Goddard Space Flight Center (GSFC) is working on a project with a Russian project, called "IKI", with a 256Kbps link. This project is very heavily space science oriented on the first tier. Low speed, high speed is all NASA has planned in conducting space Cooper [Page 38] Internet Monthly Report June 1994 science projects between NASA and IKI. Currently, NASA's lines are all synchronous. The Russians have suggested using asynchronous lines, as there are problems in Moscow with synchronous. The big question, "Will it ever work?" Cooper [Page 39] Internet Monthly Report June 1994 Appendix RIPE NCC Activity Plan DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT DRAFT R.Blokzijl 1 January 1994 Version 2 1. Introduction The RIPE NCC has been working since 1 April 1992 on the basis of an Activity Plan defined by RIPE in 1991. In September 1993 the work of the RIPE NCC has been reviewed by a RIPE panel; the results of the review have been approved by RIPE, and have been published as document ripe-099. Based upon the review activity, the review panel recommended that a new RIPE NCC Activity Plan should be adopted, better reflecting the actual work of the RIPE NCC. This has resulted in the current document which constitutes the RIPE NCC Activity Plan for 1994 and 1995. Subsequent sections give background information on RIPE and the RIPE NCC. A full description of RIPE NCC activities is given, together with reporting mechanisms. Finally, administrative procedures for change control of the Activity Plan are defined. 2. Background 2.1 About RIPE RIPE (Reseaux IP Europeens) is a collaborative organisation open to all European Internet service providers. The objective of RIPE is to ensure the necessary administrative and technical coordination to allow the operation of a pan-European IP network. RIPE does not operate a network of its own. RIPE has been functioning since 1989. Currently more then 60 organisations participate in the work. The result of the RIPE coordination effort is that the individual end-user is presented on his desktop with a uniform IP service, irrespective of the particular network his or her workstation is attached to. In December 1993, more than 500,000 hosts throughout Europe are reachable via networks coordinated by RIPE. The total number of systems reachable worldwide is estimated at close to two million. Cooper [Page 40] Internet Monthly Report June 1994 2.2 About the RIPE NCC The RIPE Network Coordination Centre supports all those RIPE activities which cannot be effectively performed by volunteers from the participating organisations. Besides supporting RIPE activities in general, the RIPE NCC provides the following services to network operators: o network management database containing information about IP networks, DNS domains, IP routing policies and contact information o delegated Internet registry, a clearing house distributing Internet numbers (most importantly address space) o domain name system (DNS) coordination o graphical maps of IP networks o repository for network operations software o RIPE document store o interactive information service The RIPE NCC started operations on April 1st, 1992, and currently has 3 permanent staff members. The RIPE NCC is embedded in RIPE. This means that the RIPE NCC Activity Plan is defined by RIPE, and that the RIPE NCC reports, at least, to RIPE on a regular basis. The RARE association provides the formal framework for the RIPE NCC. 3. Technical - Coordination Activities 3.1 Internet Registry for Europe The RIPE NCC will will act as the European registry for the delegation of Internet numbers. The RIPE NCC will perform this function in close cooperation and coordination with a. The Internet Assigned Numbers Authority (IANA) b. The global Internet Registry (currently the Internic) c. Local Registries of European service providers In exceptional cases the NCC can act as the Registry of last Cooper [Page 41] Internet Monthly Report June 1994 resort for European organisations. 3.2 Maintain a database of European IP networks and their management information. The database to be maintained will contain several classes of objects. These objects are described in detail in ripe-13. At the moment the following object classes have been defined: a. Networks b. Responsible persons c. Domains d. Routers e. International lines f. Name Servers The NCC will be responsible for the database entries; this includes a. collection of database entries b. checking of individual entries c. checking of consistency and integrity of the database Quarterly reports on changes in the contents of the database will be produced, together with statistics about the number of database entries. 3.3. Distribution of the database. Secondary copies of the database can be installed at other sites upon request. It is the responsibility of the NCC to keep track of such secondaries. The RIPE NCC will provide assistance to local registries in setting up secondary database servers. An up to date record of secondary sites will be maintained on line. 3.4. Coordination of database exchange with other organisations. The NCC will coordinate and execute the exchange of database information with NCC's outside Europe. The result will be that for the end user of the database one uniform set of global information will be available. Cooper [Page 42] Internet Monthly Report June 1994 3.5. Keep a record of operational contact points. This will consist of a list of NOC's and responsible people that will be used as a reference list for the individual NOC's to be used in case of network related incidents, including security incidents. Individual NOC's will be able to subscribe to a weekly update service. 3.6. Placement of name servers and backup servers in Europe, and beyond. On a regular basis the interworking between the DNS name servers in Europe, and their connections to name servers outside Europe, must be checked. Detected errors and inconsistencies must be reported. Corrective actions must be followed in case of severe problems. The result will be a consistent set of name servers. 3.7. Referral Services. The RIPE NCC will perform a Referral Service for Internet Service providers. The NCC will do this in a fair and impartial way. 3.8 Coordination with Local Registries. The RIPE NCC will keep close contact with Local Registries in Europe. The RIPE NCC will assist such registries in setting up and maintaining their services. This activity may include presentations on the work of the RIPE NCC for broader audiences, such as relevant conferences and workshops. It may also include coordinated development of common tools. 4. Technical - Development Activities NICs and NOCs and the NCC need special purpose software tools for their work. While some of these tools are available commercially others will have to either be obtained from the public domain or specially developed to suit local needs. The NCC will collect, develop, document and test such tools in order to make them available to the RIPE community. While some basic support will be given the NCC will not provide full support for these tools. Cooper [Page 43] Internet Monthly Report June 1994 4.1. Database management tools. Tools for management of the database and their maintenance are an important work item for the NCC. The result will be the availability of a consistent database. 4.2. Database querying tools. Development and maintenance of the whois utility. The result will be a program, available from a file server, that permits remote interrogation of the database. 4.3. DNS quality control tools. Utilities for quality control of the interworking of the DNS name servers will be developed and maintained. The result will be a set of software and documentation, available from a server. On an ad hoc basis special projects are taking place inside the RIPE NCC. These projects are funded separately, but the NCC may give administrative, management and technical support. Therefore the following activity is defined: 4.4. Special projects. The RIPE NCC can participate in special projects that have been approved by at least the RIPE community. The nature of the participation can be administrative, managerial or technical. The total amount of NCC participation should not exceed 20% of the NCC resources. Results of the special projects will be publicly available. 5. Administrative - RIPE Activity Support The NCC will give the following support to the RIPE activities: 5.1. Keeping the RIPE document store. The NCC will keep RIPE documents online and easily accessible to the RIPE community. Copies of other document stores relevant to the RIPE community, such as the repository of RFCs, will equally be provided. Modern document retrieval utilities will be installed and maintained to facilitate access to the document store. Cooper [Page 44] Internet Monthly Report June 1994 5.2. Technical and secretarial support for studies undertaken by RIPE. The NCC will provide technical and clerical support for RIPE studies and working groups in order to enhance continuity and coordination of the work between RIPE meetings. 5.3. Organisational support for RIPE meetings. RIPE meeting attendance is expected to be on the order of 80 persons, meeting three times a year. The NCC will provide clerical support to organise these meetings in order to keep them productive. 6. Administrative - Reporting The NCC will follow the following general reporting procedures: 6.1. Quarterly reports an all activities will be produced for the RIPE participating organisations and the RIPE NCC funding organisations. 6.2. Quarterly reports on outstanding problems will be produced for the RIPE participating organisations and the RIPE NCC funding organisations. 6.3. The NCC reports on its ongoing work and outstanding problems also to each RIPE meeting. These meetings take currently place three times a year. 6.4. The NCC will produce annual reports. These will be available on the 31st of January following the year to be reported on. The annual report will contain a summary of the activities and an overview of the financial situation. All reports produced by the RIPE NCC will be publicly available. 7. Review and Change Control The functioning of the RIPE NCC based on the current activity plan shall be reviewed in the fourth quarter of 1995. The review panel will consist of at least the Chairs of RIPE and the RIPE Working Groups. The current Activity Plan can be amended on request by a full RIPE meeting which includes the organisations that are funding the RIPE NCC. Cooper [Page 45] Internet Monthly Report June 1994 Report on the Current Activities of the Following Groups: - IETF User Services Area - RARE ISUS Working Group - EARN's EARNINFO Group Joyce K. Reynolds, 25th January 1994 IETF - User Services Area Last Meeting: Houston, Texas November 1993 Area Director: Joyce K. Reynolds - The User Services Area of the IETF is a second level group - providing help to teachers, trainers, etc., in the form of documentation to take to their end-users - the first level. - The IETF is an open, technical group which defines and develops protocols for the Internet. - Current User Services Area Working Groups include: - Integrated Directory Services (IDS) - Integration of Internet Information Resources (IIIR) - Internet School Networking (ISN) - Networked Information Retrieval (NIR) - Network Information Services Infrastructure (NISI) - Network Training Materials (TRAINMAT) - User Documentation (USERDOC2) - Universal Resource Identifiers (URI) - User Services (USWG) - Whois and Network Information Lookup Service (WNILS) - The User Services Area Council (USAC) "FYI RFCs" For Your Information - Request for Comments - FYIs are a subseries of RFCs. Cooper [Page 46] Internet Monthly Report June 1994 - FYIs are introductory and overview documents for ALL LEVELS of network users. - Purpose to make available general information, rather than protocol specifications. - Currently, 21 FYI RFCs. - Two new - ready to be published: 1) ISN - FAQ for Primary and Secondary Schools 2) Update to FYI4. - IETF User Services Area and RARE ISUS continue to work in parallel and in a complimentary fashion, with coordination between Jill Foster and Joyce Reynolds. RARE WG3 - RARE ISUS Working Group Last Meeting: Warsaw, Poland October 1993 Chair: Jill Foster - RARE ISUS covers a broad range of people and activities where most of the work is done in task forces. - It is a volunteer effort and is open to everyone interested in participating. - Current activities and Task Forces include: - RARE Technical Report 1 - UNITE - User Network Interface to Everything - Multimedia Information Services - Networked Information Retrieval (NIR) - Coordination of NIR in Europe - User Documentation - Document Delivery - Network Training Materials - Support for Special Interest Groups - User Requirements of Automatic Mail-Based Servers - At the RARE ISUS meetings in Warsaw, two announcements were made: Cooper [Page 47] Internet Monthly Report June 1994 1) Jill appointed to chair INET/JENC94 User and Applications Support Track. 2) Jill resigned from ISUS as Chair. EARN - EARNINFO Last Meeting: Warsaw, Poland October 1993 Chair: David Sitman - EARN covers a larger geographical area than RARE, which includes Europe, the Middle East, and Africa. - EARNINFO meetings are usually attended by those attending the EARN technical meetings, not specifically made up of user support people. - The "real work" is performed by a paid staff. - EARNINFO focuses on general end user issues. - Two interesting projects in process: 1) NETFIND - EARN Pilot 2) "Guide to Network Resource Tools" - EARN/RARE ISUS Cooperation Issues? A merger between EARN and RARE is not impossible and could be desirable, but on the other hand, something may also be said of healthy competition. For Further Information: 1) Trip Report was filed in the Internet Monthly Report (IMR). 2) IETF User Services Area Report (see below). Cooper [Page 48] Internet Monthly Report June 1994 IETF User Services Area Report Houston, Texas Joyce K. Reynolds (USAD) November 1993 10 working groups in the User Services Area of the IETF met in Houston, Texas. Integrated Directory Services (IDS), chaired by Tim Howes and Chris Weider. (Summary reported by Tim Howes.) The IDS Working Group is chartered to facilitate the integration and interoperability of current and future directory services into a unified directory service. This work will unite directory services based on a heterogeneous set of directory services protocols (X.500, WHOIS++, etc.). In addition to specifying technical requirements for the integration, the IDS Group will also contribute to the administrative and maintenance issues of directory service offerings by publishing guidelines on directory data integrity, maintenance, security, and privacy and legal issues for users and administrators of directories. The IDS WG reviewed, discussed and/or progressed the following documents. Held up, pending more vendor responses, "X.500 Implementation Survey". Held up, pending a query to Paradise, "X.500 Pilot Project Catalog". Coming "soon" (within the next month), "WHOIS++ Implementation Catalog", "Model for Information Privacy of Directories", Legal Issues for Directories in Europe", "Data Management Issues", and "Overview of Directory Services". Also discussed was the inclusion of the CSO nameserver protocol in the IDS effort (consensus was to include it), and the more general issue of how do we make all these directory services work together (lots of ideas, but no solid conclusions, yet). Integration of Internet Information Resources Working Group (IIIR), chaired by Kevin Gamiel and Chris Weider. (Summary reported by Kevin Gamiel.) IIIR is chartered to facilitate interoperability between Internet Information Services, and to develop, specify, and align protocols designed to integrate the plethora of Internet information services (WAIS, archie, Prospero, etc.) into a single "virtually unified information service". Cooper [Page 49] Internet Monthly Report June 1994 Clifford Lynch discussed his paper on using the Z39.50. Margaret St. Pierre discussed the Internet-Draft, "WAIS over Z39.50 1988" (St. Pierre et al). This draft is being considered as an informational RFC profiling the use of Z39.50 version 1988 by the traditional WAIS protocol. The idea of quality assurance was discussed. Quality assurance in this context addresses such issues as invalid pointers to data objects, interoperability among the current information systems and the ability to contact information maintenance personnel. A mailing list is now established called quality@sunsite.unc.edu. The idea of a data types registry was discussed and Greg Vaudreuil agreed to write a document on using the MIME content type registry in Amsterdam, but that document was never posted to the IIIR list. Applications Co-Area Director John Klensin indicated that the document had been denied by the IESG based on the fact that it undermined an existing RFC. Internet School Networking (ISN) session chaired by Jennifer Sellers (NASA) and Art St. George (NSF). (Summary reported by Jennifer Sellers.) The Internet School Networking Working Group is chartered to facilitate the connection of the United States' K-12 (Kindergarten-12th Grade) schools, public and private, to the Internet, and school networking in general. After a period for introductions of those attending and a statement of their interest in ISN, the group launched into a discussion of whether it should continue to exist. With a tentative decision to continue activities, a revision of the body of the charter began. This was accomplished, and minor refinements and word-smithing will take place on the list. April Marine reported on her action item to investigate the InterNIC's ability and willingness to maintain a directory of people in primary and secondary school education who are involved in networking. The group then defined a set of milestones which will take the group through March, 1995 and was therefore permitted to go to lunch. April's report was considered in crafting the milestones. Networked Information Retrieval (NIR), chaired by Jill Foster and George Brett. (Summary reported by Kevin Gamiel.) NIR is chartered to increase the useful base of information about networked information retrieval tools, their developers, interested organizations, and other activities that relate to the production, dissemination, and support of NIR tools. NIR is a cooperative effort of the IETF, RARE, and CNI. Cooper [Page 50] Internet Monthly Report June 1994 Jim Fullton gave the current status of CNIDR. Jill Foster gave an overview of RARE activities in this area. The working group split into small groups to discuss each section of the NIR status report as a final review. Section 5, mailing lists and gopher among the major areas changed. It will be sent to the list for final comments. April Marine discussed the "checklist" history. She has put together a simple NIR tool checklist. The Network Information Services Infrastructure Working Group (NISI), chaired by April Marine and Pat Smith. (Summary reported by Pat Smith.) NISI is exploring the requirements for common, shared Internet-wide network information services. The goal is to develop an understanding for what is required to implement an information services "infrastructure" for the Internet. Documents: The Internet-Draft on international NIC structures and RFC 1302/FYI 12 will be completed/revised by the Seattle meeting. NIC-Profiles: This information will be revived, working in cooperation with the InterNIC. NISI Future: Good discussion about the scope and role of NISI including possible future projects. Various plans discussed, including possibility of ending the group and having a new group emerge if needed, with different name and focus. Further discussion to take place on the list followed by action in Seattle. Network Training Materials (TRAINMAT), chaired by Jill Foster. (Summary reported by Ellen Hoffman.) The Network Training Materials Working Group is chartered to enable the research community to make better use of the networked services. Towards this end, the Working Group will work to provide a comprehensive package of "mix and match" training materials for the broad academic community which will: 1) enable user support staff to train users to use the networked services and 2) provide users with self-paced learning material. In the first instance, it will not deal with operational training. This Working Group is the IETF component of a joint RARE/IETF group working on Network Training Materials. The ongoing work towards a training materials catalog was reviewed. The template for materials was reviewed, with recent changes suggested by Pete Percival incorporated. The WG agreed with the newest version. Sample entries developed by a team working with Margaret Isaacs was Cooper [Page 51] Internet Monthly Report June 1994 reviewed, and the WG agreed that the focus should be on training rather than documentation or resource guides, the latter which could be included in a bibliography rather than in the main part of the document. Sample subject headings were reviewed, with the agreement that these might change if documentation and guides were removed from the body of the catalog. Additional volunteers were recruited to complete putting materials from the University of Newcastle catalog into template form, with the goal of adding new materials once this task is completed--about half the original Newcastle entries are already in template form. Updates will be sent to the email list. Discussion also focused on materials which might need to be developed in the training area, particularly the usefulness of videos. The final segment of the session included discussion of efforts by other groups, and a roundtable on what attendees are doing in the training area. User-Doc2, chaired by Ellen Hoffman and Lenore Jackson. (Summary reported by Ellen Hoffman.) The User-Doc2 Working Group is preparing a revised bibliography of on-line and hard copy documents, reference materials, and training tools addressing general networking information and how to use the Internet. The target audience includes those individuals who provide services to end users and end users themselves. The User-Doc2 WG had a small but enthusiastic set of attendees due to a conflicting applications group meeting that many of the usual suspects attended. The UD group set a new record by having everyone in the room volunteer to assist in writing and reviewing documents in progress! A "Not Quite an Internet Draft" bibliography was distributed and discussed which will update RFC 1175. The new document will focus on books, journals and other bibliographies rather than all possible documentation. A section will be developed to cover RFCs and FYIs. The final document is scheduled to be completed before the next IETF. A second document covering Internet connectivity is almost ready for review, and will be distributed to the WG list. This is a joint project with the ISN WG. Uniform Resource Identifiers (URI), chaired by Alan Emtage and Jim Fullton. (Summary reported by Alan Emtage.) URI is chartered to define a set of standards for the encoding of system independent Resource Location and Identification information for the use of Internet information services. The URI WG had three sessions in Houston. The first two were Cooper [Page 52] Internet Monthly Report June 1994 dedicated to closing work on the Uniform Resource Locators, which seems to have occurred. The final session worked on Uniform Resource Names. Document drafts have been commissioned to reflect those discussions. User Services Working Group (USWG) chaired by Joyce K. Reynolds. (Summary reported by JKRey.) The USWG provides a regular forum for people interested in all user services to identify and initiate projects designed to improve the quality of information available to end-users of the Internet. Gary Malkin briefly discussed the "DAWG" (Distribution and Announcement WG) idea that has been sitting on the USWG's backburner for awhile. A BOF will be held at the next IETF to see if there is further interest in this topic. Ann Cooper led a talk and discussion on the US Domain. Jill Foster and Joyce Reynolds reported on the RARE ISUS meetings and the EARN Network Services Conference which they participated in, which was held in Warsaw, Poland. Jill announced the INET94/JENC5 Call For Papers - User Information Track to the USWG. Jill was asked to run this track, and asked Joyce if she would be co-track leader. There was continued discussion from the Amsterdam IETF on Bill Manning's thoughts about how to "empower" users to utilize and document tools. WHOIS and Network Information Lookup Service (WNILS), chaired by Joan Gargano. (Summary reported by Joan Gargano.) The purpose of WNILS is to expand and define the standard for WHOIS services, to resolve issues associated with the variations in access, and to promote a consistent and predictable service across the network. Peter Deutsch led a discussion on the status of the WHOIS Architecture. Chris Weider and Simon Spero led a discussion on the status of the distributed WHOIS++ model and centroids. Chris described changes to the draft WHOIS++ document. Simon Spero described the mechanism for searching a centroid tree from the bottom, up. Jim Fullton described the status of WHOIS ++ Clients. Jim mentioned the use of WHOIS++ in support of networked information retrieval and the type of client development that is occurring as part of other application development. The session concluded with a discussion on the recommendations and modifications to the WHOIS Protocol and a discussion of WHOIS++ Implementations by Joan Gargano.

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 0016ielrtn.com.cn
