Minutes of Working Group Meeting

IfA Facility, Hilo

December 9, 2004




  1. Current Network Status
  2. On October 30 at 8:15 PM, a flash flood caused extensive damage on the UH Manoa campus, devastating the UH library and interrupting power to 35 buildings. Running the network core from 4 portable generators, UH-ITS was able to restore the Internet and services to the Big Island around 2:00pm on Oct 31. DNS service was also restored later that day.

    In the next few days, there were small interuptions as UH-ITS disconnected the generators and returned power to the Hawaiian Electric Grid.

    The JAC summit router, running an old version of IOS, was exhibiting the same symptoms as the old CFHT router. The JAC network traffic has been rerouted through their Hilo router awaiting an upgrade to their summit router.

  3. Wireless on the summit
  4. Pui Hin has received a complaint of an oberservatory using wireless equipment on the summit and reminded everyone that wireless is not allowed on the summit. Everyone can help keep the summit wireless free by notifying the network administrator of the offending observatory. Sometimes users might be using wireless equipment without the knowledge of the administrator.

    There was a discussion on whether the Bluetooth technology -- which functions at 2.4 gigahertz, even though it's designed for short range and low power -- will be harmful to the radio and submillimeter telescopes. Mac Cooper from SMA was asked to look into the possibility of a study on this, perhaps in cooperation with VLBA.

  5. Southern Cross 10Gbps dual rings - connection to MK Observatories
  6. The NSF proposal, submitted by UH-ITS in conjunction with USC and UW in May, has been selected for an award. However, the amount awarded is much less than requested. Also NSF Cyberinfrastructure -- which is part of Computer, Information Sciences, Engineering Group -- is clear that they are funding backbones for science; not local connections. The current plan for Hawaii is to first establish the connection point at Spencer Beach while looking for alternate funding for the connection to MK. CANARIE, a funding agency in Canada was interested in providing funding for high speed connection to CFHT. Since this will involve cooperation among UH-ITS, AARNet, and CANARIE, a meeting has been planned for February 1st at CFHT to talk about the possible ways to utilize the AARNet 10Gb for the CFHT connection, how it might benefit the rest of MK, and the costs in preparation for a proposal to CANARIE.

  7. Extension of Mauna Kea Observatiories DS-3 Verizon Services Agreement
  8. Pui Hin distributed new pricing from Verizon which includes rates for 300Mbps and 1000Mbps bandwidths.

  9. Report from MKO Users' Meeting
  10. As done last year, Pui Hin presented statistics on the reliability of the network. Between October 2003 and September 2004, there was a total system-wide downtime of 30 hours. That makes 99.65% availability compared to 99.8% the year before. This year's downtime includes a 21 hour outage caused by fiber damage along the Saddle Road.

    On behalf of the MKOCN working group, Pui Hin recommended to the committee the installation of fiber between the main building and the dormitory buildings at HP and Cat6 cable into the rooms for Internet Access.

    Also Pui Hin reported on the Verizon network rate reduction on Mauna Kea and the lauching of the Southern Cross Cable Network. She alerted the directors of a February meeting for CANARIE, NRC, AARNet, UH to meet and discuss with the observatories ways to upgrade the network bandwidth to the summit of Mauna Kea.

  11. Other Discussions
  12. An incident occurred where UH-ITS blocking of TCP port 53 was suspected to have affected email delivery for CFHT. It is UH's policy to block the port unless there is a special request with source and destination, mainly for DNS zone transfer only. Pui Hin will ask UH-ITS for a list of filtered ports for future reference.

    There was a discussion on whether the implementation of NAT is necessary for the wireless network at HP. There were diverse opinions: Ryu Ogasawara, for example, would like the extra security; while Kevin Cornwell thought that all PCs should have their own firewall protection anyway. Pui Hin will look into a small router to be used for NAT only.

    There was a discussion on how DNS secondaries should behave when the network is down.

  13. Next meeting
  14. March 10th Thursday, 10:00 AM at CSO, Hilo

    Note: This meeting has been rescheduled for April 7th.
