Actual attendees:

General

Johari is setting up a web landing site for the Malaysian collaboration.  The start is at http://pinger.unimas.my/pinger. It will contain:

• brief history, description of the project and the objectives
• link to main SLAC page and also NUST
• list of names, contact details (email, etc), their affiliation, and they scope of job in the project
• a link to the data collected from UNIMAS and also other hosts in UM, USM, and UTM when they have their monitoring host running
• link to meeting minutes in Confluence
• we need to add Bebo as an advisor

It would help to have an MoU between SLAC and the UTM. Les has sent a request to his legal folks to ask how to proceed and whether he can share the UNIMAS MoU with UTM and UM.  He hopes to hear back in the coming 10 days. We will also need agreement to share from UNIMAS.

Workshops

Johari is putting together a web site for the workshop at UNIMAS.

Johari recommended a future PingER workshop later this year. This time it would be in a Peninsular Malaysia site hosted at either UTM or UM. Hanan at UTM has agreed to take the lead.  We need to get 4 or 5 universities involved. We will need travel funding to fund Les. Les has provided his CV to assist in the paper work. This may be associated with a thesis review or something similar. Update?

We need to set some dates. Anjum prefers it to be out of semester time but that is not critical. Les has a constraint  starting July 12th through August 4th. Hanan may have a constraint early June.  Malaysia has a lot of public holiday. What is the period that we are looking at? (June - July?), 

A quick list: 10th July to 8th August is fasting month (Ramadhan); 25.05.2013 - 09.06.2013  School Holiday in Malaysia. 

Apart from that, if we target a lot of academicians, then the best time would be during semester break, we will get the dates for that.

*Should we set up a Doodle page, see http://doodle.com/?locale=en*. ?

Funding

Johari has submitted a proposal for FRGS (Fundamental Research Grant Scheme). There are 5 members of the proposal (5 is the max). Johari decided to get 2 more people from the group in UNIMAS to join the PingER project, thus we are unable to include our counterparts in UM and UTM (Dr Abdullah and Prof Hanan). We can go for a bigger project such as the eScience or LRGS (Long-term Research Grant Scheme) which can accommodate a larger number of people, more funding and encourage cross institutions collaboration.

At a later stage the infrastructure and data can be used for research in: anomaly detection; correlation of performance across multiple routes; and for GeoLocation. Johari would like to see UM and UTM, which are research universities, strongly engaged in the next round of research proposals. Anjum mentioned a paper on Evaluation of IP Geolocation Algorithms on PingER and PlanetLab Infrastructures, by Fida Gilani et. al. submitted to IEEE INFOCOM 2011UNIMAS. This could be updated with new data and maybe submitted to a different venue. Anjum forwarded a copy of the paper to Johari, Abdullah and Hanan with copies to the team. The idea is to see whether there is interest at UTM, UM or UNIMAS. Johari has put together a draft that has been reviewed by Anjum. It will need to be shared when closer to completion. Update?

UNIMAS

There is a problem with the UNIMAS traceroute. It appears pinger.unimas.my is behind a NAT that is not passing the traceroute UDP probes. Other hosts at UNIMAS are not seeing the problem, so Johari believes it may have to do with the IPTABLES in pinger.unimas.my. Traceroute using the -I option (send the probes using ICMP rather than UDP) seems to work (but needs root access). Thus it would appear not to be in the return (ICMP "time exceeded") response. The probes (when not using the -I option are UDP packets using sequentially ports 33434 - 33465 for up to 30 hops). It is possible that ports > some number may be blocked.

Johari has set up a guest account for Anjum. Anjum logged on and reported some concerns about addresses and interfaces not matching. The traceroute/ping server is important for the TULIP trilateration project and also understanding routing within and from Malaysia.

Johari was out of town and had limited Internet connection until 21st feb 2013. Also he realized that the ssh and ftp server is not running since the previous reboot, thus he was not able to make any changes to the UNIMAS website until he gets back and manually start those two services.

UTM

The UTM Pinger site is http://pinger.fsksm.utm.my/cgi-bin/ping_data.pl to get the data. .  

The traceroute server is also running. It is at: http://pinger.fsksm.utm.my/cgi-bin/traceroute.pl. Saqib discovered the problem was a timeout in traceroute.pl. Saqib has extended the timeout and it works.

Saqib is starting to look at Pingtable.pl anomalies as a start in a case study for Malaysia and S.E Asia. The general idea of the case study is to be found at: https://confluence.slac.stanford.edu/display/IEPM/Malaysian+Case+study. Saqib is making up a list of hosts in Malaysian states that respond to pings.

UM

Dr Nor Badrul Anuar Jumaat has installedl PingER on a cloud at UM. The machines are virtualized and  running Ubuntu Linux. Anjum pointed out that at NUST they are having a problem with a virtual machine running pinger2.pl and the /tmp/ disk space filling up. Anjum is exploring this in more detail, so at the moment it is just a head's up. Johari has sent Kashif's workshop presentations to Dr. Nor.   The name and address of the server is  pinger.fsktm.um.edu.my (202.185.107.238). The UM monitoring host has been added to the NODELIST PingER meta data base at SLAC a nd the <HostList> for Malaysian and S.E Asian hosts has been added to the pinger.xml file at UM. We need to get the latest pinger2.pl installed. Since the traceroute is working, "we" can start to make a routing study similar to https://confluence.slac.stanford.edu/display/IEPM/Routing+from+UNIMAS.

NUST

From Arshad: Rector has agreed to support one person visit to SLAC. Raja has been nominated.  Cybersecurity wanted a rsiks and  mitigations document. It has been created and accepted. Raja's invitation letter has been signed by the CIO. It was sent to the Associate lab Director last Friday.  It should be sent soon. 

*Arshad and the NUST Rector visited UM and UTM earlier this week. They visited *UM Monday at about 1030AM along with the NUST Pakistan delegation. They visited the Deputy Vice Chancellor and the EE Dept in Faculty of Engineering. At this occasion they also sent email to Abdullah, Fidah, Badrul, and Salwa, to engage in a discussion on  collaboration in the PingER project being pursued by NUST team in partnership with Stanford Linear Accelerator Center (SLAC) USA. 

It will be an honor to meet all the colleagues at this occassion. Look forward seeing you all.

Any feed back?

Kashif reports that the  Multan PoP node was under observation for many days. Now its working fine with little bit of un-reachability. It has been added back to the list of Monitors in the meta database.

Potential projects

See list of Projects

Ipv6

With Malaysia moving quickly to IPv6 (already Nava at USM has sent Les an IPv6 address that he recommends monitoring), converting PingER (especially the gathering, analysis) work with IPv6 is an interesting problem. Anjum believes he could provide an undergraduate to start on this.

Bebo's suggestions

(1) Creative visualization of PINGer data including rich interaction;

(2) Publication of PINGer data in Linked Open Data formats thereby increasing its usefulness to other researchers.

If these are of interest, Bebo is willing to work with students who come to SLAC and remotely with students at UNIMAS and NUST. Bebo believes that both of these areas have great potential for papers within the conference communities with which he is directly involved. 

With PingER going back over a decade, its presentation tools tend to be a  bit jaded having in some cases been developed in the 90's. New, modern ways to access display and navigate the data would be a  big plus.

Coordinate and lead the installation of PingER monitoring at multiple Malayisan sites

Build and install a new http://www-iepm.slac.stanford.edu/pinger/tools/pingER-2.0.2.tar.gz file with the improved version of pinger2.pl

PingER at SLAC

The annual report to the International Committee for Future Accelerators (ICFA) Standing Committee on Inter-regional Connectivity (SCIC) has also been completed. 

TULIP

Raja has completed the MATLAB script and used it to generate some input files for Pakistan and Europe. However using the alpha values (function of both region and RTT value) found through the alpha analysis the distances were underestimates in some cases. He is working on finding the cause and possible solution.
