Actual attendees: Anjum, Kashif, Raja, Ridzuan, Saqib, Belo, Les
Hassaan was not notified about the meeting since he is not on the pinger-my email list. Les will send email to Badrul to get him added.
Administration
Anjum is at UM. He does have access to the Internet from the Lab but its a shared place and he cannot attend meetings while in the Lab. For meetings, either he shall attend it from his home, or from the common room of the building.
- UUM are interested to host a PingER workshop at UUM in 2014. However, they have two issues, one is the budget (they need to run this workshop on cost recovery basis); second is their commitment to MYIGF which is hosted by UUM (btw 12-13 august). There was no update 3/5/2014.

Ridzuan successfully setup hadoop environment for the servers. He is now looking into how best to input the pinger data to the environment and type of analytics that can be done. . Ridzuan is working through some issues due to lack of IPv4 addresses and the need to use IPv6.
Ibrahim Abaker is planning to work on a topic initially entitled " leveraging pingER big data with a modified pingtable for event-correlation and clustering", The purpose of this project is to make Pinger more efficient and more scalable to retrieve and analysis pingER raw data. Consequently it may improve pinger data store. He is planning to use key-value store model with high expandability and shorter query response time. The benefit of such project will help in the design of real time analysis and distributed pinger data across multiple servers for analysis. Les has sent him a pointer to documentation on the data flow at SLAC and also listings of pingtable.pl and associated script. He is currently writing a proposal, which will contain a problem statement, objectives, scope and the approach to tackle the problem. He asked: how much PingER data is captured and stored so far (~ 1TByte)? Is there a published paper (see http://www-iepm.slac.stanford.edu/paperwork/ieee/ieee.pdf)?
UNIMAS
Bebo & Les will set up a Skype meeting with Renan to get an update and see about setting up direct contact between Renan and Ibrahim. Ibrahim provided a copy of his proposal (see https://confluence.slac.stanford.edu/download/attachments/17162/leveraging%20pingER%20big%20data%20with%20a%20modified%20pingtable%20for%20event-correlation%20and%20clustering.docx).
UNIMAS
No No progress 2/19/2014. Johari was not on the call.
The The Raspberry Pi is at the data centre, but due to miscommunication, the public ip which was previously assigned to the rasp pi unit has been assigned to another server. So now Johari has to wait for the ip to be reassigned back to rasp pi unit and give new ip to the other server. They suggested a new ip for the rasp pi unit but Johari wanted to have the old one so that we do not have to update the record at slac for the archival process, etc

The PingER monitor at SEECS/NUST (maggie1) is being rebuilt on a different computer following a crash.
At the Connect Asia Pacific Summit in Bangkok in Januaryt and seeing the project "Mapping the pan Asia Pacific information Superhighway and closing gaps in infrastructure connectivity" Shahryar found that very much related to the work in the PingER project. So Shahryar sent email to a UN agency for a possible collaboration with them on PingER project. He has heard nothing so he will write a detailed proposal and then should contact them again. No update 2/5/2014.
Hassaan reports that they have established contact with people in Bahawalpur. The contact person forwarded the request to higher authorities for approval of PingER deployment.
The contact at Sahiwal did the installation of PingER node by himself but data is not being collected, so we are in contact to resolve the issue. Kashif believes he missed some Linux updates. Today is holiday here and he will do the trouble shooting on 6th Feb.
We were gathering data from Pingerisl-air (this is continuing to work), and Quest (stopped working Feb 13)
We are still unable to gather data from airuniversity, buitms, cae, duhs, pingerisl-qau, sau.seecs.edu.pk , uaf.
Monitors Status
Airuniversity New installation will be install in a week
Buitms Problem in hardware, they are trying to fix it. System Replacement Required
Cae Problem with IP, they are trying to resolve it
Duhs They are purchasing new servers in two week time
pinger.pern.edu.pk Fixed Feb 19.
Pingerisl-qau Contact person is still on leave. He is now busy in other pending works.
There are 2 approaches thta can be tried in parallel:
- Rebuild from scratch. in the initial case Umar took 2-3 weeks. he wrote documentation, so this will be a test of the documentation. This could be valuable should Malaysia or another site decide to set up an archive. kashif and Joun are ready to start on this.
- Dump and restore the database. This is much easier. However it requires the database password. Les will contact Umar to see if he can provide the password. Umar canot logon to maggie1 since it is blocked by the firewall.
The BeaconList at NUST and SLAC are out of sync. Raja will compare the two pinger.xml files. It turns out NUST was not using the HostList for the non Beacons and so had ane xpanded BeaconList which was updated from SEECS. Raja has explained this to NUST and believe it will be easy to synchronize.

The installation of PingER at sSahiwal is complete. It just needs the Beacon List.

Uaf Problem in system, visit approval for Faisalabad University in progress. Approved for 12th Feb, visit approval for Faisalabad University in progress. Approved for 12th Feb
Kashif reports (2/19/2014): "We are in a process of shifting us along with equipment to another lab from a week. Due to this transition process and new installations, Joun could not contact further to the contact persons about the down PingER Nodes. This shifting process will complete on coming Friday and after that i will be able to update you about the task on NUST part."
TULIP - Raja
Please try out http://www-wanmon.slac.stanford.edu/cgi-wrap/reflector.cgi?function=vtrace It is a visual traceroute. It uses TULIP to locate the routers. It is in beta test and needs testing by friendly users. We are looking to add a link to it from the perfSONAR home page.
...
Raja has also re-written the historical traceroute facility that takes nightly traceroutes and allows one to retrieve and compare them. He then extended it to use the reverse traceroute facility to provide histories for NUST, CERN, UM as well as SLAC. When the UNIMAS and UTM traceroutes work, we can include them. See for example http://www-wanmon.slac.stanford.edu/cgi-wrap/traceroutearchive.cgi
Three is an empty pinger/xml file at ICTP. Les & Raja are studying. The Pinger hosts at FIU in Florida is now restored. Les is contacting the Jordanian PingER monitor contact to restore it.
