Adib is waiting to hear from colleague (Dr. Nordin: chair of ISTT2014), there was no update as of this meeting. The conference is 2 days so the workshop may be squeezed to one day. The conference will be held in Langkawi between 24-26 Nov.
Hopefully, this will help us to attract good number of participants and get sponsor/support to cover our expenditure. Other option is to conduct the workshop in UUM, we are ready to provide Local Arrangement (lab, local transportation, and food). But there is no funding provided by the school to support the transportation/accommodation of the speakers.
- Anjum reports (6/23/2014) that "the proposal for conference has been submitted for approval and Pinger has been added in the agenda. Travel expenses for you and Bebo have also been included in the conference proposal. We are awaiting the proposal approval. If the proposal gets approved, we can then decide on wether to actually conduct the Pinger Workshop at UM or at another place. I am saying this because I believe a stand alone pinger workshop will be more preferable.
As discussed earlier, the only twist here is that Pinger will be seen as a case study for big data. This is good in a sense that people interested in doing research in the domain of big data can deploy pinger monitoring nodes at their respective universities/organisations and in return, play around with the data.
We have to wait for the approval of proposal for conducting the workshop at UM. Tentative Dates are 24th and 25th November 2014." Les will be in Burkina Faso Nov 13-21. He flies back to London on Nov 22nd. He can get to Malaysia mid morning November 24th. Thus the workshop should be at the end of the ISTT2014 meeting if Les is to attend.
- Bebo will be Western Australia, Okinawa and possibly Singapore in November. Bebo is in the UK and will send his expected dates/finalize his travel plans this week and send an itinerary.
- Anjum suggested putting together a paper on metrics provided by PingER for Sigmetrix. The due date is in November.

Ridzuan has put together a rough proposal to use Hadoop to store and make available PingER data. He is evaluating several vendors version of Hadoop 2.0 installations to decide which is the right one to adopt. Last time he successfully installed and tried Hadoop 1.0 but then it has many drawbacks such as no real-time streaming processing. Johari sent information on the Myren Cloud. The web site is as follows: https://cloud.myren.net.my/. It gives information about the service and how to apply, plus user guide is available from the website. As for Ridzuan, he should be eligible to register for the service, but he needs to check with UM (University Malaya) procedures for applying for the service. No No word from Ridzuan 6/4/2014.Requested update 6/23/2014
Ibrahim Abaker is planning to work on a topic initially entitled " leveraging pingER big data with a modified pingtable for event-correlation and clustering". Ibrahim has a proposal, see https://confluence.slac.stanford.edu/download/attachments/17162/leveraging+pingER+big+data+with+a+modified+pingtable+for+event-correlation+and+clustering.docx. He is currently spending time reading about RDF storage and its retrieval, also he is trying to setup Hadoop clusters for the experiment. He is in email discussion with Renan on which part to work on first. He plans to collaborate with Renan to make the pinger store and process more efficient. Les has sent him documentation of PinGER which is very helpful. Ridzuans' work is more to do with hosting the data and stream data analysis. Ibrahim is looking more at applying MapReduce ( programming model for processing large data sets with a parallel, distributed algorithm on a cluster), reducing the storage needs and providing querying of the data. No word from Ibrahim 6/4/2014. Requested update 6/23/2014.
UNIMAS
Dr. Adnan Shahid Khan who recently joined UNIMAS, will be joining our PingER group and will help with the current PingER initiative in UNIMAS. Once he is up to speed on PingER he will join the group.
The Raspberry Pi is at the data centre and has a public IP address. It was working last week, until the UPS failed over the weekend. It did mnot not reboot itself. Johari will look at the problem.
The tool to enable synchronizing Malaysian monitors is completed. It has been tested by Saqib. Saqib requested to add sorting the HostList by country, Johari will add this.
The traceroute server at http://pinger2.unimas.my/cgi-bin/traceroute.pl has the same problem as before. They know (sort of) the problem but haven't got the chance to rectify it (mapping NAT address, needs to be added). There is no progress 12/4/2013, 1/8/2013, 1.22.2014, 2/5/2014, 3/26/2014, 4/8/2014, 4/23/2014, 6/4/2014. Now that the historical traceroutes are working for UM (see below) there is an extra incentive to get the reverse traceroute working at UTM and UNIMAS
Johari has a research student who finalized a proposal in order to officially apply for his masters. He will start in February. He is currently working on threshold/anomaly detection, and will extend to correlating performance over multiple routes. He will share the proposal with Les and others April. No progress 6/4/2014.
UTM
No updates regarding traceroute problem at UTM. However, Saqib thinks the problem is still in CICT firewall or router as tcp traceroute command works fine from UTM.

The latter two report a problems problem with accessing the httpd file on the latter two. However, this does not interfere with their correct working. The issue is quite strange. For some reason apache can't access the /etc/httpd/ directory when ping_data.pl is called from the web but from the terminal it works just fine (both as root and apache).
