Inverse Query Failures
by Daniel Karrenberg 17 Jan '97

17 Jan '97

I was asked to look into invers queries going wrong in order to determine which additional indices might be useful. I looked at 5245997 recent queries 6236 (0.11%) of which were reverse. Of these 1428 (24.72%) failed because no match could be found and 461 (7.39%) failed because either no attribute name was given or an attribute name which does not have an inverse index was given. Unfortunately no more details are logged about the latter type of failures. We will change that a.s.a.p. and report back if there are signigficant findings. I have looked at the data that was logged and could detect no clear trends pointing to the need for additional indices. Daniel

RE: Immediate - Date in Changed field
by Wilfried Woeber, UniVie/ACOnet 17 Jan '97

17 Jan '97

Hi DB-folks! On a slightly different aspect, and assuming that we change things anyway... How about running the RIPE-DB (and maybe gradually all the others :-) on a UTC basis, according to some recent suggestions? Just for a sneak preview on one of the small agenda items for the DB WG :-) Wilfried. ~~~~~~~~~~ Dear Database WG members, We have been requested to ease the restrictions on the date in the "changed" attribute to allow for dates with 4 digit years specifically those starting with "19" and eventually "20". For obvious reasons, we agree with this proposition. However, we also understand that some of you may have software which presumes the date has the yymmdd format. If anyone has a serious problem with this change, please notify me personally (orange(a)ripe.net) before the end of the week. If we don't hear any show stoppers before the end of the week, we will proceed. Thereafter, the following will be acceptable formats: 19yymmdd 20yymmdd (eventually) yymmdd Thanks for your ear, -- Carol Orange --------------------------------------------------------------------------------

As an example we ourselves register all our objects (inetnum, routes, persons...) in RIPE database (because we are in Europe). However, among others we peer with MCI and MCI insists on having route objects in their registry in order to allow routing. If the route objects are secured by hierarchical authorisation in the RIPE database we would also like to have them secured in the MCI registry. Following the scheme above MCI would have to include inetnums (while it is a pure routing registry) *and* would have to generate top level route objects allowing specific access by us to our route objects (this is a very tiring job especially regarding "the swamp" 192.x). Of course, they could copy from RIPE database... (ask them why they don't...) I guess, this problem may only be resolved by the GRR (which is yet to come) From the ongoing disussion I conclude for myself (at the current state of the discussion) that we can not impose a strict security mechanism at the time being without breaking too many things. Maybe, I am too dumb to see a simple solution which might be just at hand... I will summarise the things said here on the mailing list for the routing wg session next week and try to think some more about it (I guess, Daniel was right from the start when he said that we should begin with a bare notification mechanism...)

An AUP for the RIPE DB ?!
by Daniel Karrenberg 16 Jan '97

16 Jan '97

Another short discussion paper. As you see I'd like to keep this general issue separate from the immediate measures discussed in the other paper. Again comments are welcome. Daniel Some Toughts about an Acceptable Use Policy for the RIPE Database Scope This is a discussion paper intended to lay the groundwork for the development of a more explicit acceptable use policy (AUP) for the RIPE database. Motivation For the past six years we have been able to avoid the issue of codifying acceptable use of the RIPE database because the user community was limited. Conventions and peer pressure were sufficient to prevent abuse. This is changing rapidly. Therefore I believe we have to develop a written AUP and enforce it. Format As with any AUP is it difficult to anticipate any potential usage. It is even impractical to codify something for all usages that can be envisioned. In our case a good approach would be to list a number of common usages that are clearly acceptable, such as searching for contact points in case of operational problems or access by routing policy tools. Subsequently we can list a number of usages that are clearly not acceptable such as obtaining addresses for mass mailings or unauthorised changing of data. I think it will be rela- tively easy to obtain consensus about that. One can then state that any use which is comparable to one of those listed falls under the policy for the listed use. Any use not comparable at all will need to be determined by the database WG and added to the AUP. Enforcement If we have a written AUP and consensus that it should be enforced the NCC can get legal advice on how to best enforce it. However I would like to have the AUP defined first because otherwise thinking about enforcement tends to be less effective and also influences our goals, e.g. the desired AUP. Further Steps I'd like to see some discussion and resolution on two issues: Is an explicit AUP needed? and Is the format sug- gested above appropriate?

Preventing Abuse of Postal&Email Address Info
by Daniel Karrenberg 16 Jan '97

16 Jan '97

Dear colleagues, below you find a short discussion paper with concrete proposals to address some abuse of the RIPE DB which we start seeing. It is input for that point at the meeting next week. Comments welcome. Daniel Short Term Measures to Protect Postal and E-Mail Address Information in the RIPE Database Against Abuse Scope This is a discussion paper about immediate measures to pro- tect postal and e-mail address information stored in the RIPE database against abuse. Mass mailings are the kind of abuse we are focussing on. There is consensus that these activities clearly constitute abuse of the RIPE database. An general acceptable use policy is a separate issue that needs to be addresses separately. Current Situation The database can currently be accessed by WHOIS, WAIS and as FTPable files. A copyright notice appears at the top of the FTPable files: Copyright (c)1992/.../1997 by Daniel Karrenberg and TERENA Restricted rights. Except for agreed Internet operational purposes, no part of this publication may be reproduced, stored in a retrieval system, or transmitted, in any form or by any means, electronic, mechanical, recording, or otherwise, without prior permission of the RIPE NCC on behalf of the copyright holders. Any use of this material to target advertising or similar activities are explicitly forbidden and will be prosecuted. The RIPE NCC requests to be notified of any such activities or suspicions thereof. The access methods most suitable to obtain mass mailing data are the FTP and WAIS access methods. New Trend During first six years of operation no significant abuses of the database have come to our attention. In the past few months however there have been at least two instances where addresses from the have been sold or otherwise re-dis- tributed to address mailings. The NCC has taken appropriate action in these cases. I believe that this is a significant trend and we have to take measures to prevent such abuse in the future. In the following paragraphs I will outline pos- sible measures to that end. Assert Copyright More Prominently Currently the database copyright is asserted only in the FTPable files. Therefore any user of data obtained via other services may claim not to be aware of the copyright. In past discussions I have argued against cluttering WHOIS output with copyright notices. In the light of developments I now recommend to insert a one line copyright notice at the top of each WHOIS response roughly like: % Copyright (c)1997, see http://www.ripe.net/.... for details I have not checked yet whether this is sufficient notice in terms of legal procedures. However a user can then no longer claim ignorance. A similar solution needs to be implemented for the WAIS service. Remove Person Objects from FTP Access Person objects should be removed from public FTP access. This means both removing the person.db file and the person objects from the ripe.db file. The main purpose of these files is to allow mirroring of the database and convenient local access for various purposes. The mirroring function- ality has to be maintained differently. See below for details. The convenience of other uses in my opinion does no longer justify the potential for abuse this convenient public access has. Of course individual access can be granted if the user has a valid reason and agrees not to further distribute. Restrict Access if Abuse is Suspected I would like the database WG to explicitly authorise the NCC to restrict access to the database if abuse is suspected. The restrictions I envisage are artificial exponential delays if query patterns suggest abuse and blocking access for individual users as an ultimate measure. Of course any such measures will be reported back to the database WG. Consequences for Mirror Sites All these measures have little effect if any mirror site does not implement them. Therefore I propose that mirror sites will have to agree formally to implement any restric- tions the RIPE NCC has to implement. Further the mirror sites will have to change the procedure to obtain the person information to a restricted method. Further Steps I encourage everyone to critically read the proposals above and give me feedback, especially on aspects not considered. I ask the database WG to endorse the measures proposed and to give guidance on how they should be published, i.e. does this need to be written up as a RIPE document or is it suf- ficient in the database WG minutes/archives.

Person-Objects with multiple adresses + phones
by Nacamar AS Guardian 15 Jan '97

15 Jan '97

Hello, there are a number of persons with multiple _entries_ in the RIPE-Database, because they have multiple _adresses_, and I think, this is not handled well with our current implementation. To make this more acceptable for such people, something like the following should be possible: >>> person: Thomas Peters remarks: -- #1 - Main office: address: Thomas Peters address: Nacamar Data Communications GmbH address: Frankfurter Strasse 141 address: D-63303 Dreieich address: Germany phone: +49 6103 9901 14 fax-no: +49 6103 9901 18 e-mail: info(a)nacamar.net remarks: -- #2 - South office: address: Thomas Peters address: Herd-Weg 8 address: D-69198 Schriesheim OT. Ursenbach address: Germany phone: +49 6220 9111 25 fax-no: +49 6220 9111 259 e-mail: peters(a)nacamar.net remarks: -- #3 ... nic-hdl: TP65-RIPE ... <<< This applies too for people working as tech-c for several companies. It should be possible for each address-block to have its own phone/fax/eMail with it. As I understand the operation of the database now, all phone-numbers etc. are collected together, so the relationship to the addresses are lost.
