Re: NCC#2005110645 [ris] IPv6 bug fix patch for libbgpdump-1.4
by RIPE NCC RIS 09 Nov '05

Hi Young, Thanks a lot for the feedback. I totally understand your point. We have some internal stuff that needs to be changed in addition to Quagga fix. I'm adding it into our ToDo list. Whenever we will have time, we will look into it. In general, if you will have any other comments about the RIS services, we will be happy to hear it. Regards.

AS3333 <> RIS problems over the weekend?
by Rene Wilhelm 08 Nov '05

08 Nov '05

One of those rare occasions where someone from Nanog uses RIS, but now he got confused by the vast number of updates coming to RIS from RIPE NCC (AS3333) over the weekend. Could one of you enlighten him (or the list at large) what caused this? -- Rene ---------- Forwarded message ---------- Message-ID: <2ed0bc680511061121v288974f9jdf3bf99466bb6568(a)mail.gmail.com> From: NetSecGuy <netsecguy(a)gmail.com> Sender: owner-nanog(a)merit.edu To: nanog(a)merit.edu Date: Sun, 6 Nov 2005 14:21:00 -0500 Subject: Re: BGP terminology question At the risk of sounding like a total moron, can anyone explain what is happening here?

Shane, > Rene, in future maybe you should be clear who you expect to handle an > issue. "someone" sometimes resolves things, but not always and you can > never be sure. sorry, at the time of writing I wasn't sure what caused this and who was best to answer (ops not having send or me having missed an update on the router upgrade state). Meanwhile, I found another, probably related, issue which I'm again not sure if people (ris ops ?) know about and whether it's on SED or OPS to check: RIS DB insertion for rrc00 is running 3+ days behind: http://www.ris.ripe.net/cgi-bin/rrcstatus.cgi ---> rrc00 - last DB insertion - 2005-11-04 19:45:00 A quick look on halfweg showed the rrc00 update files (one every five minutes) which usually were 10-30 kilobyte had grown to order(8 MB) from friday evening to sunday evening. I can imagine this takes a long time to process (if the DB can store it at all). -- Rene

Hi Arife, Thank you very much. If the public CVS is available, it will be very convenient if there are any further more patches.
