HEPiX IPv6 Working Group - Meeting using Vidyo 13 Feb 2014 Present: Keith Chadwick, Alastair Dewhurst, Simon Fayer, Thomas Finnern, Costin Grigoras, Bruno Hoeft, Dave Kelsey (Chair), Ewan MacMahon, Edoardo Martelli, Mark Mitchell, Francesco Prelz, Duncan Rand, Ulf Tigerstedt, Chris Walker, Tony Wildish. Apologies: Fernando Lopez Munoz. 1. Dave welcomed all to the meeting. The agenda was agreed. 2. Minutes of January F2F meeting. Dave thanked Ulf and Francesco for producing the minutes of the F2F. Comments or updates are still welcome. 3. News. Dave reported that our CHEP2013 paper revisions had been accepted. The proposal for a pre-GDB day on IPV6 on 10th June 2014 at CERN has been approved. 4. Roundtable reports. a) Imperial. Duncan reports that he has entered info about FTS3 configuration on our web. He has also made updates to other software asset entries to best of his knowledge. b) INFN. Francesco reports that the patch to the ISC DHCP server is finished and it works. There is no more news from CNAF. c) Nordic. Ulf has today started testing dCache with xrootd (a pre-release version) but is waiting for the patch for xrootd client version 4). The discussion on FTP protocols in dCache has the good attention of the dCache developers. The errors are now in xrootd rather than IPv6. d) DESY. Thomas reports the installation of a new certificate and a reboot. e) Oxford. Welcome to Ewan M. Ewan reports that they are starting to rollout IPv6 with a test setup from their local network team. They have a dual-stack UI running EMI3 on SL6 and a handful of UK/GridPP people have accounts. He offers others to ask for accounts should they wish them. They also have an IPv6-only DPM server, a CE and some dual-stack worker nodes. f) FNAL. Keith reports that their local network team will shortly reorganise the IPv6 address space. g) ALICA. Costin reports that they have deployed IPv6 fully on ALICE central services. This does not break IPv4. They are waiting for xrootd V4 before trying to use IPv6 clients. h) Queen Mary UL. Chris reports some progress with STORM on a VM but it is not quite there yet. He has also been looking at PerfSONAR. i) KIT. Bruno reports that they now have a dCache V2.8 system and will shortly start testing. They will also configure CREAM and BDII. j) PIC. Fernando reported by email before the meeting. We joined the IPv6 perfSONAR bandwidth and latency mesh done by Duncan Rand. http://netmon02.grid.hep.ph.ic.ac.uk:8080/maddash-webui/index.cgi?grid=HEPiX%20IPv6%20sites%20-%20IPv6%20throughput%20test The dual stack perfSONAR bandwidth is as today a virtual machine. We will activate (reinstall) the production perfSONAR in dual stack next week. 5. Testing status and plans. Tony reports that there is nothing much new since the January meeting. Still many transfer problems. It had been thought that KIT problems had been solved but these are still not fully resolved. NDGF traffic is not seen. ACTION: Can all sites check whether they are receiving IPv6 traffic from the testbed. If not please contact Tony. Note that Marek's NAGIOS box is testing GridFTP hosts. Alastair reports progress inside ATLAS. He has been informing them of the IPv6 work and will talk with developers soon. They are starting to develop testing plans and he will give a talk on IPv6 at the ATLAS software week at CERN. Glasgow, Oxford and FZU Prague have been added to AGIS as dual-stack to allow some testing. Would like to add the Imperial CE and WN to ATLAS. Noted that we need more IPv6 CEs. Mark comments that Glasgow is willing to provide IPv6 services for testing. Ewan adds that Oxford is also happy to join. Next meetings: 10-11 Apr 2014 F2F meeting at CERN Notes by Dave Kelsey. 13 Mar 2014
