Hi guys I don't really have any opinion either way as to whether this list is discontinued. But as it is a RIPE list and not a RIPE NCC list I think it should at least be proposed to close it with some justification rather than an announcement of a decision. I can see from the archive that it has not been used very much recently, but maybe that is because it is already shown on the web site as an inactive list. Just for some historical background, this list was intended as a self help forum on database issues. Users of the RIPE Database could ask questions about specific problems or more general issues about usage of the RIPE Database, how other members interact with the database and what tools, if any, they use. Other users could offer advice and the RIPE NCC would only contribute if any questions were left unanswered. So is it considered that there is no need now for a self help forum? Should all questions be directed straight to the RIPE NCC via ripe-dbm or should such questions now go to the DB-WG? If the latter then the description of the DB-WG mailing list should be amended to reflect this. (btw the web site still lists Wilfried as the chair :) ) cheersdenis From: Alex Band <alexb(a)ripe.net> To: db-help(a)ripe.net Sent: Wednesday, 16 September 2015, 13:27 Subject: This db-help list will be discontinued Dear colleagues, We are going to discontinue this mailing list, db-help.

Hi Reihane I don't think anyone monitors this db-help list now. I have seen several questions go unanswered on here. But I can answer the question for you. You are trying to create the object 2.179.95.128 - 2.179.95.255 with status 'ASSIGNED PA'. The parent object is 2.179.95.96 - 2.179.96.127 and this also has status 'ASSIGNED PA'. You cannot create a hierarchy of objects all with status 'ASSIGNED PA'. The parent object range is assigned to Islamic-Azad-University-Of-Ashtian. That is part of an allocation range 2.176.0.0 - 2.191.255.255 made to Information Technology Company (ITC). If you have been assigned the sub range 2.179.95.128 - 2.179.95.255 then you need to ask ITC to split the parent object into separate assignments. Otherwise you need to ask ITC to assign you a different range. Either way as ITC controls this block you need to talk to them. cheersdenis From: Javidi <ripe(a)dci.ir> To: db-help(a)ripe.net Sent: Tuesday, 8 September 2015, 12:29 Subject: FW: FAILED: arak1 Why does this object not create? 2.179.95.128 - 2.179.95.255 Error: inetnum parent has incorrect status: ASSIGNED PA But this is not coorect Please advise me Regards Reihane -----Original Message----- From: RIPE Database Administration local [mailto:unread@ripe.net] Sent: Tuesday, September 08, 2015 11:58 AM To: ripe(a)dci.ir Subject: FAILED: arak1 > From: Javidi <ripe(a)dci.ir> > Subject: arak1 > Date: Tue, 08 Sep 2015 10:27:40 +0200 > Reply-To: Javidi <ripe(a)dci.ir> > Message-ID: <002001d0ea18$1e780080$5b680180$(a)dci.ir> SUMMARY OF UPDATE: Number of objects found: 2 Number of objects processed successfully: 1 Create: 1 Modify: 0 Delete: 0 No Operation: 0 Number of objects processed with errors: 1 Create: 1 Modify: 0 Delete: 0 DETAILED EXPLANATION: ***Warning: Invalid keyword(s) found: arak1 ***Warning: All keywords were ignored ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The following object(s) were found to have ERRORS: --- Create FAILED: [inetnum] 2.179.95.128 - 2.179.95.255 inetnum: 2.179.95.128 - 2.179.95.255 netname: Telecommunication-of-Markazi descr: Telecommunication Company country: IR admin-c: AUTO-1 tech-c: AUTO-1 status: ASSIGNED PA mnt-by: AS12880-MNT changed: ripe(a)dci.ir 20150908 source: RIPE ***Error: inetnum parent has incorrect status: ASSIGNED PA ***Warning: Deprecated attribute "changed".

Database release 1.81 deployed to RC environment
by Alex Band 08 Sep '15

08 Sep '15

Dear colleagues, We are happy to announce the deployment of RIPE Database software release 1.81 to the Release Candidate (RC) environment. This release extends and fixes some of the functionality changes that were part of the 1.80 release, especially with regards to authenticating and creating objects. This is why we urge you, again, to thoroughly test the RC environment to make sure nothing in your workflow breaks: https://www.ripe.net/data-tools/db/release-notes/rc-release-candidate-envir… Here are the most notable changes I'd like to highlight. When using the RC environment, please focus on using webupdates to test these features: - We added auto-complete for attributes such as maintainers. This means you can start typing a maintainer name and webupdates will suggest existing maintainers, along with their associated authentication. - Webupdates tries to be smarter about deleting objects. When, for example, you want to delete a person object, webupdates will suggest you also delete the associated maintainer, if it is not referenced anywhere else. - "Create a new person and maintainer pair" (previously known as the New Organisation Startup Form) has been redesigned. After logging in with your RIPE NCC Access account, you just need to enter four fields to get going. Because webupdates contains such fundamental user interface changes, gathering your feedback has been cumbersome at times. This is why we added the Usersnap feedback widget to the RC environment, so you can highlight and annotate the page you are providing feedback on. It will make it easier for us to process your comments and implement fixes and changes. From all of us at the Database team, we are looking forward to your comments and we hope you enjoy this release! Kind regards, Alex Band Product Manager RIPE NCC

Updating maintainer objects with filtered auth lines
by Daniel Stolpe 24 Aug '15

24 Aug '15

I just had a very specific experience but this is a general problem. What I wanted to do was update a maintainer object in the database. No problems since I was authorized via a PGP key. The problem was that one of the lines looked like: auth: MD5-PW # Filtered And although I have no personal use for the md5 hash I did not want to disturb users who might have. I asked the NCC for advice and the answers were like "if you have an access account" (yes) you can add a line "auth: SSO xxxx(a)xxxx.xx" (yes). Still not a solution to my problem since adding the SSO line would just break the md5 anyway. The solution this time was that I eventually found a local copy of the object with the md5 hash unfiltered. I know the md5 hashes are a security problem and I do not recommend anyone using them but as long as they are there the filtering causes trouble. And by the way, we now see a lot of auth: SSO # Filtered What I am looking for is a way to retrieve the whole unfiltered object for anyone authorized, or, at least, a possibility to updated the object without touching the filtered lines. Maybe you could send a PGP signed request, not for updating but just for viewing the complete object?

call for application authorisation ideas
by Job Snijders 24 Aug '15

24 Aug '15

Hi group, I know all of you have automated their interactions with the RIPE database entirely. :-) As it currently stands, there are two ways to automate interaction with the RIPE DB: a) send GPG signed emails (and wait for the dumb greylisting to clear) b) call the http://rest.db.ripe.net/{source}/{objecttype}/{key}?password=XXX restful API Option A works, but is not very nice if you want something done immediatly and require a confirmation that the operation succeeded. The advantage of option A is that you don't need any auth: MD5-PW lines in your mntner object and RIPE stores no sensitive data. Option B goes very well with modern programming paradigms, but the disadvantage is that you need to have an "auth: MD5-PW XXX" line in your maintainer, and should that pass ever leak somehow it could be used through webupdates / email / api, from any location. I think all in the group agree that it would be very nice if you can perform 100% of all operations without the need for any MD5-PW. I'll even go as far as stating that we should not be looking at successors such as SHA3-PW, let's leap forward and make the PW auth concept entirely obsolete. :-) CALL FOR IDEAS ============== Now that personalised authorisation is covered and in progress, what about our poor applications? How should they authenticate with the RIPE DB? I see value in stuff like signalling to RIPE "this token can only be used for the API from this source IP address", I've also heard that OAUTH2 is magic and populair for app2app auth. Or maybe all of this is is overkill and we just need to GPG sign the payload of the requests to rest.db.ripe.net and call it a day? DB-WG, please speak up and voice your ideas! Kind regards, Job

Re: [db-wg] [opensource-wg] Question for RPSL Parser
by Stavros Konstantaras 20 Aug '15

Shane is right, I don’t have the intention to shuffle the project with Bison and Flex because 1) I don’t have the knowledge of these technologies 2) I don’t have the time to learn them 3) I want to Pythonize as much as I can and be independent as much as possible (OK maybe a little bit dependent from other Python Libraries but this is the boundary). I am sure that you guys made a great job 14 years before but now or soon RPSL will be replaced with something else so I still want my toolset to be alive by easily and quickly replacing 1-2 Python libraries. What my prototype does now is extract the attributes and values by using Regular Expressions, a solution that has already been proposed in this discussion and I think this is the way to go. In theory, it can be an easy parser based on Python’s RE but complexity starts when -for example- RPSL says “accept as-set BLABLA” instead of “accept 10.100.200.0/16" and that as-set needs to be resolved (another query to RIPE DB). But anyway, thanks for your ideas. Crazy or not, I don’t mind everyone is welcome. If I still need to reply to Tomas last e-mail but I am quite busy today.

Re: [db-wg] [opensource-wg] Question for RPSL Parser
by Stavros Konstantaras 20 Aug '15

Hi Thomas and others, thanks for your quick replies. To make things more clear, our project at NLnet Labs is the development of "a modern IRRtoolset" written in Python and targeting any operator, not just another homemade tool for our own needs. Or to say in more detail the creation of a tool that is able to configure BGP routers directly+automatically by extracting the policies from RIPE DB. This means that I am struggling to avoid the (re)use of any past or legacy software that exists, otherwise we loose independency and inherit restrictions from the past. Currently, I do have a working proof of concept with a simple RPSL parser written in Python which is able to parse simple policies with (v6)import(s)-(v6)export(s)-accept-announce-action-pref-med-coomunity attributes. Convenient I would say for many existing policies like KPN’s, RIPE’s etc. but definitely it will crash in complex policy files like GRNET’s. My current solution uses also BGPq3 to translate AS, AS-SET and ROUTE-SET and this is also something that I want to ged rid of. So I was looking for the existence of a Python Library which can do a complete job and translate any existing policy in an intermediate data structure like XML (this is what I do now). I was hoping to find one, adopt it and present our (completed) work in the next RIPE meeting (yes I know I am very ambitious, I need to slow down). * Masimo, I already checked rpsltool and discarded it. But thanks for your super-fast reply. * Tomas, thanks for pointing me to your library. I will have a look at it and check if it is convenient for our project. * George, yes you are right. This should be the #1 step, take corresponding RPSL RFCs and implement them in Python. However, that would take too much time and will not allow us to work on other missing functionalities of the prototype. And we would like to have something ready at the beginning of November. However, I will check your solution as well. I hope now that I made myself more clear. Big thanks to everyone, every help, info or idea is kindly appreciated.

Hi all WG members, For my project at NLnet Labs I would like to ask you if you know any (relatively) complete RPSL parser written in Python. I searched around and I didn’t find anything. Does someone know any repository where I can get one or maybe contact someone who has written one? Thanks in advance.
